I'd like to give you my two cents as well on how to proceed here. If nothing else, this will be a second opinion. If I could redo my physics education, this is how I'd want it done.

If you are truly wanting to learn these fields in depth I cannot stress how important it is to actually work problems out of these books, not just read them. There is a certain understanding that comes from struggling with problems that you just can't get by reading the material. On that note, I would recommend getting the Schaum's outline to whatever subject you are studying if you can find one. They are great books with hundreds of solved problems and sample problems for you to try with the answers in the back. When you get to the point you can't find Schaums anymore, I would recommend getting as many solutions manuals as possible. The problems will get very tough, and it's nice to verify that you did the problem correctly or are on the right track, or even just look over solutions to problems you decide not to try.

Basics

I second Stewart's Calculus cover to cover (except the final chapter on differential equations) and Halliday, Resnick and Walker's Fundamentals of Physics. Not all sections from HRW are necessary, but be sure you have the fundamentals of mechanics, electromagnetism, optics, and thermal physics down at the level of HRW.

Once you're done with this move on to studying differential equations. Many physics theorems are stated in terms of differential equations so really getting the hang of these is key to moving on. Differential equations are often taught as two separate classes, one covering ordinary differential equations and one covering partial differential equations. In my opinion, a good introductory textbook to ODEs is one by Morris Tenenbaum and Harry Pollard. That said, there is another book by V. I. Arnold that I would recommend you get as well. The Arnold book may be a bit more mathematical than you are looking for, but it was written as an introductory text to ODEs and you will have a deeper understanding of ODEs after reading it than your typical introductory textbook. This deeper understanding will be useful if you delve into the nitty-gritty parts of classical mechanics. For partial differential equations I recommend the book by Haberman. It will give you a good understanding of different methods you can use to solve PDEs, and is very much geared towards problem-solving.

From there, I would get a decent book on Linear Algebra. I used the one by Leon. I can't guarantee that it's the best book out there, but I think it will get the job done.

This should cover most of the mathematical training you need to move onto the intermediate level physics textbooks. There will be some things that are missing, but those are usually covered explicitly in the intermediate texts that use them (i.e. the Delta function). Still, if you're looking for a good mathematical reference, my recommendation is Lua. It may be a good idea to go over some basic complex analysis from this book, though it is not necessary to move on.

Intermediate

At this stage you need to do intermediate level classical mechanics, electromagnetism, quantum mechanics, and thermal physics at the very least. For electromagnetism, Griffiths hands down. In my opinion, the best pedagogical book for intermediate classical mechanics is Fowles and Cassidy. Once you've read these two books you will have a much deeper understanding of the stuff you learned in HRW. When you're going through the mechanics book pay particular attention to generalized coordinates and Lagrangians. Those become pretty central later on. There is also a very old book by Robert Becker that I think is great. It's problems are tough, and it goes into concepts that aren't typically covered much in depth in other intermediate mechanics books such as statics. I don't think you'll find a torrent for this, but it is 5 bucks on Amazon. That said, I don't think Becker is necessary. For quantum, I cannot recommend Zettili highly enough. Get this book. Tons of worked out examples. In my opinion, Zettili is the best quantum book out there at this level. Finally for thermal physics I would use Mandl. This book is merely sufficient, but I don't know of a book that I liked better.

This is the bare minimum. However, if you find a particular subject interesting, delve into it at this point. If you want to learn Solid State physics there's Kittel. Want to do more Optics? How about Hecht. General relativity? Even that should be accessible with Schutz. Play around here before moving on. A lot of very fascinating things should be accessible to you, at least to a degree, at this point.

Advanced

Before moving on to physics, it is once again time to take up the mathematics. Pick up Arfken and Weber. It covers a great many topics. However, at times it is not the best pedagogical book so you may need some supplemental material on whatever it is you are studying. I would at least read the sections on coordinate transformations, vector analysis, tensors, complex analysis, Green's functions, and the various special functions. Some of this may be a bit of a review, but there are some things Arfken and Weber go into that I didn't see during my undergraduate education even with the topics that I was reviewing. Hell, it may be a good idea to go through the differential equations material in there as well. Again, you may need some supplemental material while doing this. For special functions, a great little book to go along with this is Lebedev.

Beyond this, I think every physicist at the bare minimum needs to take graduate level quantum mechanics, classical mechanics, electromagnetism, and statistical mechanics. For quantum, I recommend Cohen-Tannoudji. This is a great book. It's easy to understand, has many supplemental sections to help further your understanding, is pretty comprehensive, and has more worked examples than a vast majority of graduate text-books. That said, the problems in this book are LONG. Not horrendously hard, mind you, but they do take a long time.

Unfortunately, Cohen-Tannoudji is the only great graduate-level text I can think of. The textbooks in other subjects just don't measure up in my opinion. When you take Classical mechanics I would get Goldstein as a reference but a better book in my opinion is Jose/Saletan as it takes a geometrical approach to the subject from the very beginning. At some point I also think it's worth going through Arnold's treatise on Classical. It's very mathematical and very difficult, but I think once you make it through you will have as deep an understanding as you could hope for in the subject.

These are some very broad questions, and some (like the age of the Earth) are outside the scope of biology but you are not alone and your questions, unfortunately, are common, especially for those coming from religiously fundamentalist backgrounds like yourself.

> I need to see evidence for myself.

If I showed you a murder weapon, a fingerprint that was lifted from it, and the finger print of a suspect, and you knew nothing about finger prints then the evidence, even in your hands, physically, wouldn't mean much to you. What's far more important than the evidence itself are the inferences we make from it, based on an understanding of how that evidence matters in some investigation. The same is true in biology and other fields of science.

So while you can certainly visit natural history museums and view their collections (like this or this), just seeing specimens won't really give you the whole story.

> Why should I, personally, be convinced that the Earth is billions of years old?

If you care about having beliefs that are true, then you should devote some time to understanding how we know the true age of the Earth, and the many different methods we use to demonstrate that it is indeed very old.

Wikipedia would be a great start:

• https://en.wikipedia.org/wiki/Age_of_the_Earth
  
• https://en.wikipedia.org/wiki/Radiometric_dating
  
  As is typically the case, the sources are the the bottom of each page. If you're like me and you enjoy pop-science documentaries, you might enjoy episode 7 of Cosmos: A Spacetime Odyssey, titled The Clean Room which deals with how Clair Patterson became involved with one of the first accurate methods of dating the Earth, using uranium-lead dating. It does a good job of explaining the basics of radiometric dating, why it's accurate, and why we can trust it the way we trust other scientific processes to give us good answers.
  
  > How can I better understand the Fossil record, which supposedly somehow tells us that humans and dinosaurs were not in the same time period?
  
  You likely already know that sedimentary rocks are formed in layers, with newer rocks being deposited on top of older rocks. So while there are processes that tilt distort rocks, we don't find examples of older rocks being found on top of younger rocks, and we don't find examples of rabbit fossils being in the same layers as velociraptors, for example. A lot of the evidence you're likely to encounter is a variation on this theme: things that happened a long time ago leave evidence that is separate from the evidence from things that happened more recently.
  
  While I've not personally read it, I hear it being recommended by people from fundamentalist backgrounds saying that it helped them: The Rocks Don't Lie: A Geologist Investigates Noah's Flood.
  
  > And though I get it as a concept, natural selection has always been confusing to me; I can't see how it would practically happen in real life.
  
  It might be that you're used to thinking on time scales you are familiar with. A billion years is an incredibly long time. An analogy here that is often useful is to think of the entire history of the universe, mapped onto a single calendar year, with 00:00 January 1st being the first meaningful moment after the Big Bang, and December 31st at 23:59:59 being now. In this analogy, our planet did not appear until the first week of September, and the first life appearing sometime around the middle of September. The first amphibians, descendants of lobe-finned fish, appeared around December 22nd, and the first mammals appeared December 26th. Anatomically modern humans appeared about 8 minutes before midnight on Dec 31st. You can see more examples here. I know that for me, this really helps me conceptualise deep time.
  
  Dogs are descended from wolves, and they domesticated themselves beginning a few tens of thousands of years ago. Most of the breeds of dogs you are familiar with appeared only in the last few centuries, through artificial selection. If we can go from wolves to chihuahuas in hundreds or thousands of years, it is not a huge stretch to imagine what natural selection could do over millions of years. And, we have lots of evidence to support this idea.
  
  > Because of the way I was raised, a lot of this sounds like science fiction to me.
  
  The difference between any holy book you'll read, and what we know from science, is that behind the person saying it, there is an answer to the question "how did it happen?" At most, a religious answer will involve some shrugging of the shoulders, and what frankly amounts to "magic".

Hmm, that's the thing, how to plan for... collapse? extinction? I mean, maybe some parts of the developed world can muddle through for a few decades, a little warming we can handle, but it's not a little warming we're in for- we're talking about changes that will awaken the sleeping dune seas in the American heartland- see those? A few thousand years ago, when the global average temp was about 1 degree higher than today, those dunes were alive, marching blindly across the heartland.

When we start talking about 4 degrees C average global temp, which its likely that we'll reach in maybe 5 or 6 decades barring radical GHG reduction, that's more like 9 C over land, or 16 degrees F slapped across average temperatures- here's what summer highs look like across the US as we go through the 21st century: imagine that Fargo, North Dakota is like Phoenix. Do you think they are making this up for shits and giggles? They are trying their damned best to warn us of what's coming down the pike.

Many of the coastal cities will be wrecked. Maybe you don't care about coastal liberal elites or whatever, but the fact is those blue states generate the vast majority of GDP that American power rests on. A diminishment of one is diminishment of all. American security will be further threatened as rising seas cripple American naval bases: take a walk with Rear Admiral Jonathan White down to Norfolk

Outside the borders of America, the world's economies and societies will be facing greater and greater pressures. An increase in the global average temperature of 4 degrees C has been described by scientists as "beyond the limits of adaptation" and "incompatible with organized global society." Like it or not, when America's trading partners are suffering chaos and instability, America's economy will not be immune. I personally doubt that America's constitutional order would survive the turmoil- I think America would devolve into authoritarian dictatorship under the economic strain in an attempt to guarantee a semblance of stability. As we've seen across the world and across the 20th century, once that happens, all bets for civil rights and human rights are off.

And it doesn't stop at 4 degrees- a 4 degree world has a very high chance of not being stable, because numerous feedbacks that add more and more carbon to the atmosphere will begin to engage the higher in temperature we go. There are vast stores of carbon locked away in the soil- as it warms, that carbon will be released to the air through accelerated metabolism. We will lose the Amazon, as it dies back to savanna and scrub, as well as countless other species and ecosystems absolutely unique in this universe. Dying forest will pour their carbon into the air, along with methane from the melting permafrost and shallow arctic seas- we will lose the arctic polar ice cap and its stabilizing influence on the Northern hemisphere's weather. All told these feedbacks, once engaged, are calculated to push average global temps inescapably beyond 5, 6, 7, 8 degrees C after 2100- and remember, the rise will be higher over land, 12 degrees F ? 20? There were once palm trees and alligators in the Arctic, millions of years ago, before humankind awoke. Earth's been there before, we can certainly go back.

We might revisit the ecological collapse of the End Permian extinction, when global average temperatures rose 6 degrees C. It's also called "The Great Dying"- nearly 95% of all species were wiped out, including all terrestrial vertebrates larger than about 100 lbs.
Any humans who survive the intervening chaos would watch the sun rise over stagnant, anoxic oceans largely devoid of multicellular life, outgassing toxic hydrogen sulfide.

If you think your descendants might admire that view and if you want to get a head up on your neighbors and plan for dangerous global warming I encourage you to check out Mark Lynas' Six Degrees: Our Future on a Hotter Planet. He did the work of reading through several hundred scientific research papers on the subject and collected them into a well referenced summary. Here's an incomplete synopsis: A degree by degree explanation of what will happen when the earth warms.
Try and read it soon, though- at current rates, we are closely approaching ambient CO2 concentrations that negatively affect human cognition.

So what's all this for? I mean, it must be something really precious to sacrifice our planet and our species' future for, right? Material wealth? The American way of life? What do we really want? To sit in traffic in the latest model automobile? To spend our lives accumulating imaginary points in a game where all we have to trade away is the future of the planet? Is this wealth, or is it profound poverty? Maybe it is possible, perhaps quite common actually, to live an impoverished life of material affluence, and it is quite possible, and necessary actually, for us to live rich lives of material simplicity, with ample free time to flourish in the things that make a life truly rich- love, community, friendship, knowledge, and health.

Mechanical engineer, here. There is no substitute for actually building something, which it seems you're already doing. Outside of coursework and training, I would recommend the following resources:

FUNdaMENTALS of Design: You can download the PDF here. Tons of pictures and equations. This was the "course book" I used in undergrad @ MIT, and you can get it for free! Not really organized, per se, but one cool thing about it is that it's meant to be flipped through and printed double-sided. One side is always a birds-eye or holistic view, and the opposite side is always an in-depth and theoretical treatment of the topics. This is a great way to find out, "Wow! This exists, and here's what it's called!"

Mechanical Engineering Design: This is a pretty good primer on mechanical "stuff."

Mechanisms and Mechanical Devices Sourcebook: This is a great resource to keep handy. I look at this ALL the time, especially when I hit brick walls and need inspiration or fresh ideas.

Misumi: Pretty good place to get industrial-grade mechanical components... not sure about the prices for hobby-level stuff. They also have some good literature and tutorials here.


Hope it helps, and feel free to PM me if you have any questions.

Saff and Snider is great for applied complex analysis. In my opinion it strikes a perfect balance between accessibility and rigor for a first course on the subject.

Visual Complex Analysis is another good choice, but it might be a little more advanced than what you're interested in.

The first half of Lang might also be a good choice, but Lang takes a slightly more formal, proof-based approach.

I've also skimmed through Brown and Churchill, which looks quite good but is prohibitively expensive.

Finally, you can find many cheap (~$10) books on the subject by Dover. The only one I've looked at is Knopp, which is quite formal and light on computation, but might be a good supplement. Here's another Dover book with outstanding Amazon reviews.

Complex analysis is both very elegant and very useful. Best of luck with your class!

I've worked with some designers who had books like these:

Mechanisms and Mechanical Devices

[507 Mechanical Movements and Designs]
(https://www.amazon.com/507-Mechanical-Movements-Mechanisms-Devices/dp/0486443604/ref=sr_1_2?ie=UTF8&qid=1484237480&sr=8-2&keywords=mechanisms)

Honestly though, these books might be good bathroom reading, but design comes down to experience. The more problems you solve, and the more things you make, the better your designs will be.

Having been a design engineer for a while now, the absolute best advice I can give you is to talk to the other people who will be using the stuff you design. Starting out, your designs aren't going to be the most elegant. Focus on getting something that is functional.

Then, talk to the machinist who is making the parts. He'll have some advice on what features are difficult to machine, or some features you could include that make your parts easier to manufacture, such as adding a flat surface to use as a datum for machining setups, or "bonus holes" that can be used for lifting or securing the parts on the machine. Maybe if you loosen some tolerances, he can order a piece of mill standard pipe instead of having to hog out a huge piece of round stock. Maybe if you tweak the geometry just a little bit, the part can be made on a manual machine instead of having to wait for the 5 axis CNC to open up.

Talk to the techs who have to operate or maintain the machines. What makes their jobs difficult? They'll know best what parts are hard to access, or which tightly packed assemblies don't have clearances to fit tools in, or what's constantly breaking and needs to be replaced often. They'll show you the "custom made tools" that they improvise so that they can actually work with your equipment.

Talk to the people in procurement, or your suppliers and vendors. Is there cheaper hardware you could use? Maybe switching materials would make it easier to source raw stock. Maybe there's an off-the-shelf coupling you could use instead of machining a custom bracket to join two components. These guys work with lots of other people in your industry, and will gladly share "how the other guy did it".

Set up the guitar so it's coming in orange... In general, yes, this is what you're doing to all inputs. An example of when not to do this might be if you know a musician will get hit with adrenaline and play twice as loud during the show as they might at soundcheck.

A caveat: signal coming in nice and hot at your preamp will NOT optimize your signal to noise ratio if you compensate by turning your output faders way down. This still means your PA will amplify however much Johnson noise is contributed by your mixer. Run your faders at unity, but turn down your PA if necessary. I know I've said it before but so many people refuse to follow this practice that it makes my head spin.

Methinks you went to school for this... Nope! My formal training in sound amounts to a two-day lecture on system optimization using Smaart.

I work in IT, so part of this is very similar to what I do. Awesome! I'm working on my Network+ certification right now. Being able to set up a reliable LAN for your PA control/monitoring is a requirement for professionals these days. I rarely put more than 20 devices on network, but I want to make sure I'm ready for the phone call asking me to do something ten times bigger. A lot of IT people I know (my father among them) are fantastic autodidacts thanks to a career of keeping up with the newest technology, so you likely have what it takes if you're interested enough to put in the work here.

Are there online resources for system optimization? Well, yes, there are always online resources. I'm sure there are some regulars on this sub who can direct you to some, but I can't offhand. Personally, and for most people you'd ask, the best resource for this is Bob McCarthy's book on the subject. Not an online resource, but you'd be selling yourself short if you didn't read it from the man who started it all.

Ah, sorry - I mean that's a pretty sufficient TL;DR, but if you want more of a story, I was never really a great Mormon - I always had my issues with the doctrine, only went semi-actively, and never served a mission, but after moving to SLC for a job I needed friends so I began attending a YSA ward and I was all-in. I met my wife and we became engaged. I went through the temple for the first time at 27 - it disturbed me. I never went back (other than for the wedding) and became an active NOM at that point.

Then one night, in 2014, I was on field assignment in Northern Canada. I was working night shift logging drill core and reading a book about the implausibility of Noah's Flood during my down time. I decided to see how this jived with Mormon beliefs. Well, one thing led to another and I stumbled across the CES Letter. Suddenly it all made sense - why I could never be the good Mormon I was raised to be. Why I had so many issues with the one true church.

I got home, let her know what I had discovered. She was not happy. We argued a lot over religion. A few months later we discovered we were having a little boy. She made it clear our son would be raised Mormon. I hated that because I knew he would be raised to see me as a sinner. I knew she was not a huge fan of Utah, so I decided applying for work anywhere. I ran this across her and she agreed. I figured Godless New England would be our best bet - I must've sent out 100 resumes. No luck for a year. We had our baby, I blessed him in our house, they'd go to church without me. I kept sending resumes and started expanding my locations. Seattle, Portland, Pittsburgh, New York, ... Then finally, at long last I got a job offer! ... The offer was in Detroit. I knew nothing about Detroit other than abandoned homes, but... we needed a new home, and Detroit needs new people, so it sounded perfect!

So we packed up everything, sold our house, and moved 2,000 miles to the Great Lakes State and settled in a little suburb of Detroit. She relaxed the Mormon-image that she was keeping for her family and friends over the first few months. A sleeveless shirt here, a Sunday at the park there, but yes we still argued about church and she still attended most of the time.

One Sunday morning we had an argument about the November 2015 policy. I knew her acceptance of LGBT rights and I knew this terrible policy had to bother her as much as it did me. She left for church angry and texted me about 60 minutes later, "You're right. I don't believe it anymore."

I felt so bad, but so relieved at the same time. Today we go to church on occasion, but for cultural/familial reasons; neither of us believe - though I believe she still maintains a minor NOM aspect and maintains firm belief in Christianity while I'm a bit more Agnostic. Our little boy has never been to nursery and never will. We'll be having a second kid in a few weeks and they'll never know anything of Mormonism other than, "Oh, that's that thing Grandma and Grandpa do on Sundays."

Oh, and did I mention we love Detroit? It's an incredible city! Not just because we moved here, but the history, the arts, the culture, the sports, the cuisine - it's a real big city, but at a discount price. Plus, neighbors don't judge us for not being at church. We just bought a house, and I think we may just make it a long term home.

I am not in California, but I might be able to offer some general knowledge.

> It seems like California wants us to first apply and pass the PE, and then apply for the license. Should I go ahead and start filling out all my applications and get my references ready or should I wait until I've passed to do so? I plan on taking the test in May 2018.

I would be very surprised if you were allowed to take the test without presenting your qualifications. From what I've seen in other states, qualifying for and passing the test are the major hurdles. Applying for the license is just filling out another form and paying another fee.

> The FAQ regarding EITs and other states is ambiguous. My state's EIT "License" number isn't on the NCEES website, it simply says I've passed the FE exam.

NCEES is not an official entity. They will not have any information that you don't give them. You will be applying for your license through the California Board for Professional Engineers, Land Surveyors. NCEES is sometimes used as a common application form (especially when PE's want to extend their licenses to other states), but each state sets their own rules, so you should default to the state site.

The state where you took your EIT should have a similar Board for Professional Engineers with your EIT number.

> My school's education is also unverified - does this matter?

If you apply to take your test through NCEES (I am not certain that it is possible to do so), then you will need to verify your education through NCEES. If you apply directly through the California Board for Professional Engineers, then they will have to verify your education.

> Do I need to apply for an EIT with California to take the exam/get the Cali PE or am I good to simply apply for the next exam available?

Your EIT should carry over from another state, although California has weird rules, so there is a chance that it doesn't. Check the Board of Engineering website or give them a call.

> What's the best study material for the PE exam? Has it changed out in the past few years like the FE exam has? I'll probably take a course since I've always found it helps. I didn't study for the FE since I was just coming out of school but I've heard the PE is a different animal.

I found the PE to be easier than the FE, and have heard the same from others. I just bought the reference manual and made sure that I was familiar with it. Careful, there are different versions for different subject matter. Make sure that you don't have to buy it twice to get everything that you want.

But don't worry about it too much; for now, just look at the Sample handout to get a sense for what good design looks like.

I mention AoPS because they have good problem-solving books and will deepen your understanding of the material, plus there is an emphasis on proof-writing when solving USA(J)MO and harder problems. Their community and resources tabs have many useful things, including a LaTeX tutorial.

Free intro to proofs books/course notes are a google search away and videos on youtube/etc too. You can also get a free library membership as a community member at a nearby university to check out books. Consider Aluffi's notes, Chartrand, Smith et al, etc.

You can also look into Analysis with intro to proof, a student-friendly approach to abstract algebra, an illustrated theory of numbers, visual group theory, and visual complex analysis to get some motivation. It is difficult to learn math on your own, but it is fulfilling once you get it. Read a proof, try to break it down into your own words, then connect it with what you already know.

Feel free to PM me v2 of your proof :)

> You seem to be forgetting the minor point of agriculture failing -- or is that no longer "your point"?

How is this not willfully obtuse, if not an outright misrepresentation?

I was the one suggesting that more northerly locations would be better situated to avoid temperatures driven to 45°C+, and you responded by pointing out that even Moscow "gets heatwaves" too.

I then demonstrated that Moscow has never experienced temperatures in the 40s. Ever.

A perfectly relevant refutation of your generalised exaggeration. That's all.

> water is going to vanish, everywhere?

Obviously not what I'm saying.

Some won't get enough, and some will get far too much. And some will even get just the right amount for some time - but at some point in a collapsing biosphere, not reliably enough in any one place to ensure sufficient crop survival and reliable harvesting to make agriculture viable.

No, I don't have a crystal ball, and can't tell you exactly where that point will be, but this extinction event is unfolding with unprecedented speed, and we are still accelerating it, so I really don't believe that ignoring uncomfortably pessimistic sources is a wise strategy.

> You're now blaming me for not engaging in threads I wasn't involved in?

Sorry, I was getting it confused with the other thread we're discussing similar matters in. I have to do all this on a crappy, broken smartphone since I don't use a computer, so no split-screen windows/advanced clipboard functionality/fancy keyboard for me.

It was referenced in this thread, not the other one.

> On the contrary, I've pointed out the "links" (really one link posted multiple times)

Since /u/Goochymayn posted the link to the projected effects here, I have posted a dozen different links that weren't this one in this thread.

> Man, you people are obsessed with this one website

Far from it, though a little stubborn in trying to encourage some sort of engagement with it on your part - it's sort of the opposite of cherry picking, to go on blithely claiming that it doesn't say what it does, and that the whole thing's just too silly to even acknowledge.

I read many websites, have read the book this summarises by Mark Lunas (FWIW, it won the 2008 Royal Society Book Prize and was turned into a National Geographic TV series, so it's not just some crappy little blog.)

And I agree it would be better if the summary had hyperlinked references. I don't post it here much/ever myself, precisely because of the lack of easy to follow hyperlinks to make it easier for people to check sources online. The book is better (books are always better than this internet rubbish.)

OK, you don't recognise it or any of its sources (though they've been bandied around here often enough,) - I will add some more links tomorrow when I've had some sleep, though it will be at the expense of speedily responding to your other posts (lots of busy-ness ATM.) I will come to them when time allows.

I accept that the descriptions of the effects at each temperature band may not be accurate. Which is why it would be interesting and useful to discuss what it actually predicts, and how much, if any merit there is to their arguments (it would be even better to discuss the book, but that's less feasible online in the temporary conversation cloud that is Reddit, given how few people have probably read it.)

It's less productive in the extreme, to only ever see it analysed by McPhersonite fanboys, too busy obsessing about the doom to look at it with a critical eye. But if they are accurate, then farming will self-evidently NOT be possible, because we will all be too extinct to practice it.

Other interesting topics exist of course, but they're pretty academic if we're looking anything like +7°C by the end of the century.

That too is an interesting topic in itself, and one I would like to see more people engaging in disputing, rather than just avoiding having to consider it at all on the one hand, or obsessively and unproductively doom-mongering about on the other.

They both seem like less productive (if understandably human) approaches.

I find it convincing enough to have committed to taking the measures I have anyway, though I try to keep an open mind.

> doesn't say what they claim it does. It literally doesn't say it.

It doesn't say exactly QUOTE farming will not be possible UNQUOTE, but FFS, it's predicting the sky effectively catching fire because of the methane content, superstorms at least as extreme as the ones that caused the Permian-Triassic extinction, with ""super-hurricanes” hitting the coasts [that] would have triggered flash floods that no living thing could have survived."

It says: "That episode was the worst ever endured by life on Earth, the closest the planet has come to ending up a dead and desolate rock in space.” On land, the only winners were fungi that flourished on dying trees and shrubs."

And you think agriculture will be possible in this?

It is true, this is at 5+°C, but they also state "Chance of avoiding five degrees of global warming: negligible if the rise reaches four degrees and releases trapped methane from the sea bed."

You've made no effort to refute any of this - you just refuse to engage with this source.

It explains the inexorable runaway temperature effect that will be (possibly has already been,) initiated, and so 4°/5°/6°/7°/+ is largely irrelevant - it's going up, up, up.

And the methane is already being released in observably huge quantities already at <1.5°C, so this does not look so unlikely that it's sensible to simply dismiss it to me, considering the fucktons of the stuff there is down there.

But hey, you've got potatoes and trees, so you'll be fine.

I (and probably other less optimistically- inclined folk here,) would be really interested in knowing why you, or other more optimistic folk, think this is not going to happen.

IF (and I freely admit that is not certain, but if) we're looking at anything like these projections coming to pass this century, then at some point this century, agriculture WILL fail.

And IF the runaway effect from all these tipping points we're burning through is real, then over some timespan, that's inevitable.

> A little emotional, aren’t we? The part where "the world" = "modern civilization"?

No. The part where everything bigger than a lystrosaur, including very probably humanity, is rendered extinct.

And actually I don't get emotional about it - I'm past that.

I get stubborn, and start building an Ark.

> The article they keep linking to doesn't say what they claim it does.

It claims unsurvivable, extinction-level conditions are coming, so yes - it does say what they claim (whether or not it's well-founded - that is a different argument. One you seem unwilling to engage in.)

> I've said that multiple times to them. They have no response for me. And neither will you, I expect. Read the goddamn article.

I have. And I can understand what it's saying. I'd like a reason to disbelieve it, but you're evidently unable to provide one.

I recommend reading the book (I ought to buy another one - lent it out, and never got it back.)

Shigley's is great for learning how to design and why you design the way you do. It's the book I used in college and still reference at work. I'm not so sure it'd be great for a novice engineer. For a more practical approach, I'd recommend a few below (not necessarily in this order):

1. Machinery's Handbook - This is regularly seen as the [mechanical] engineer's bible. It has nearly everything you'd need to know for design. Most of the machinists used this in a shop I used to work in. Nearly every engineer in my current job (and there are a hundred or more) have a copy of this at their desk.
   
2. Pocket Reference - This is kind of (loosely) like Machinery's Handbook but much more broad. It covers a little bit of everything from engineering, to vehicle maintenance, to plumbing. I like it for it's all-around information.
   
3. Handyman In-Your-Pocket - this is by the same author as #2 but is tailored to the building trades. I also have this but I haven't used it much yet. Not because it's not useful, just because I haven't gotten around to it.
   
4. Marks' Standard Handbook for Mech. Engineers - I have an old copy of this book from the 80s, I believe, that my dad gave to me. It is also on the same order as Machinery's Handbook, but instead of covering EVERYTHING, it goes into more depth about the topics it does cover. If I remember correctly, it covers topics ranging from how to make a weldment to how to design a power generating steam boiler and turbine.
   
5. Solutions to Design of Weldments - This is a new one to me. I recently went to the Blodgett Welding Design Seminar and this was one of the reference materials they handed out. I had a few text book sized design guides by Omer Blodgett that I've often used, but this one seems to take all of the info from those books and condense it down to a handbook. Best part is that it's only $3.50 for a copy and I think (but I'm not sure) that it ships for free.
   
   A nice free reference manual that includes all sorts of design equations is the NCEES reference handbook. I used it back when I took my FE exam (the first exam you take before you become what's call a "Professional Engineer" in the US). It's a nice PDF to have around, though it doesn't go into a lot of explanation as to what the equations are.
   
   A few web resources I use are: http://www.engineeringtoolbox.com/, http://www.roymech.co.uk/
   
   I'm sure I'll think of some more and, if I do, I'll update this post.
   
   Hope that helps.
   
   

It sounds like you are looking at building a pair of speakers.

You need to buy the latest version of this book:

http://www.amazon.com/Loudspeaker-Design-Cookbook-Vance-Dickason/dp/1882580109

And read it front to back. Twice. It will answer many of your questions; it's well worth the price. I studied the first edition way way back.

Parts Express and Madisound are fine for parts.

Expensive? Let's put this in perspective. How many hours would it take you to build as good a set of cabinets as you can buy for $130 each on Parts Express? I assume that's what you're looking at. Trust me, unless you're a woodworker (or don't care what they look like) the cost in time is worth WAY more than that to get a good cabinet.

Want to 'cheat'? Get yourself a pair of cabinets from a thrift store or garage sale -some old pair with walnut veneer that are heavy and maybe have blown drivers. Seriously. You can ditch the drivers, add some material inside the cabinet to reduce the volume to what you need, put in a new front plate and drivers, and oil up that old walnut and you're in business.

What makes a speaker $10 and one $200? Engineering and quality construction and performance. Bear in mind that you reach a point of diminishing returns with drivers; you might get 95% of the performance of a $200 woofer with one that only costs $150. Is that extra 5% worth the cost?

Check out this man's work:

http://www.linkwitzlab.com/

Engineers don't come any finer than this man, he's amazing. Read everything he writes and check out his projects.

What you need to do to make your project sound good is do tons and tons of reading and research into what others have done. Find projects that have been built and refined and are known to be successful. Build one of those first. Remember, your time is valuable. You could waste a lot of money and time on something that sounds disappointing.

I built some speakers and subwoofers (more suited to DIY for beginners than 2-3 way designs) and came to realize that it's a mix of sound engineering and art. And lots of time.

Good luck!

I see a lot of parallels in your story to my own. I became an evangelical at 18 -- fully committed and ready to evangelize the world. I met a Christian girl and got married at 20. At 23, I went to Bible college with the intention of going into ministry. At 27, I graduated and attempted to plant a church (and failed badly). By 29, I was in a full depression because I realized that ministry was not for me and I had wasted my education. Also, I had rushed into a marriage with someone that I wasn't really compatible with; we believed that putting Jesus at the center of our marriage would solve all problems. It wasn't working. And on top of that, we had multiple miscarriages in our attempts to have children. I was pretty damn miserable all around, even though I'm pretty good at putting on a smiling face and soldiering on.

My religion was the one thing I sunk deeper and deeper into to find comfort. And the deeper I went, the more I alienated myself from society around me, and from reality.

I scuttled all ministry aspirations and found a much better career path. Things were turning around. We even managed to produce a couple of kids. That was when my wife of 15 years announced she was moving away and was going to take the kids. She had no career, no income, and no solid plan. Fortunately, I easily won the ensuing custody fight.

I found myself back in the dating scene as a middle aged man. After 15 years of married sex, there was no way I could just turn off sexual desire. I had several monogamous, adult relationships over the next decade.

Now, if I could draw a graph of my faith over time... the peak would be at age 18, with a gradual but noticeable decline over time. There would be peaks and valleys, but a steady, downward trend.

My prayer life, also over time, went from very complex, lofty prayers to increasingly simpler and more direct declarations. Towards the end, my most common prayer was a simple, "God help me," chanted over and over and over, because I had never really known God to answer my prayers in specific ways.

27 years after my profession of faith in a Baptist church, I find that my faith is completely bankrupt. I can't honestly say that the gospel of evangelicalism ever worked as promised.

I decided that I was going to put it all on the table and reboot. I would find out what was true and real in my faith, and start building from there. That meant reading material I had long avoided, and opening doors I had intentionally left shut.

I read this book about geology and the flood. I knew for a long time that the Bible accounts didn't line up with science. It was time to own up to it.

I watched this video about the real history of God and the Jews; that fucking blew me away. I had never heard of these things.

For about two weeks, I devoured every critical resource I could get my hands on. And like you, I knew that I had to follow truth, no matter where it led. By the end of those two weeks, I had nothing left to base my faith on.

That was four and a half years ago. The first few months were a little rough, but also exhilarating. But every day got a little better. Where I'm at now, I am so much happier.

It took me a few months to get the hang of what I look for. It's still hard for me to describe what I look for, but it's mostly small press (books they only printed a few of) and also very specific non-fiction books.

Like recently, I sold a cookbook for hyperactive children from 1979 for $35. If I look at textbooks, it's usually ones with very specific or rare subjects, like http://www.amazon.com/gp/product/1420062107 which I sold recently as well.

I don't just look for hardcovers or books that are in good condition. For me, it's all about subject matter. Paperbacks do just as well, as long as it's got information someone wants to read about. I've sold many discolored and loosely bound paged books, and haven't gotten a complaint because I mention everything wrong in the description.

It's so random when the books sell. I've had books sitting since I started, or I can sell a book the day I got it. I always try to make sure it's the cheapest or second cheapest on Amazon so that it will sell quicker.

I've only been doing it a few months, and it took a lot of trial and error, but it's become a lot easier for me to spot a book that may be worth a little something. Having a smart phone and the Amazon app helps, too. If it doesn't have a UPC code, I'll type the title into the app just so I don't have to lug every book home. Also having a Goodwill Outlet that charges 25 cents by the pound for books helps as well.

Well, the guy was not a real pro...

Like I said, it seems that you look more for feedback than for learning anything - there are enough free resources out there to learn anything.

Tutorials:

https://www.youtube.com/watch?v=TEjOdqZFvhY like this - it looks cheesy, but is most informative full course on youtube

Channels of plugin companies like Fab filter, Waves, Izotope etc.

Many genre producers have posted breakdowns of their tracks on youtube...

I suggest getting some stems of released tracks and analysing them.

https://www.amazon.com/Mixing-Audio-Concepts-Practices-Tools/dp/1138859788/ref=sr_1_1?s=books&ie=UTF8&qid=1540366561&sr=1-1&keywords=mixing+audio&dpID=41e%252BBcVrTZL&preST=_SY344_BO1,204,203,200_QL70_&dpSrc=srch

Btw, for the price of something like a berklee course you can get an album mixed in a "pro" studio (considering that you are noone, they shouldn't charge much - something like 100 usd per song).

I suggest focusing on the your music, you will get more from a composition course - see Avicii's early tracks were dogshit in terms of mixing, but they were good musically and later he could afford way better mixing engineers to do all the technical work. (From what I've heard, even the best mix won't get your posted songs to become excellent.)

BTW, many EDM songs are just layers upong layers of compression to get it loud, which is considered a bad mix. If you just want to get loud, learn more about limiters, multiband compression and clippers, and saturation.

I'm an aero engineer and not a CivE, but I did take the general-discipline EIT exam after college and I can tell you that it's as easy as everyone says. If you've been working with a construction company and have an engineering mentor, you could probably study ~200 hours with a companion such as Lindeburg's FE Civil Review Manual and pass the exam. Obviously YMMV depending on how good you are with math and critical thinking skills, but the caliber of the FE/EIT exam is nowhere near the PE one.

As for a second Bachelors degree, it's never too late to get one and I highly encourage you to do it if that's what interests you and it's within your financial means to do so. When I was getting my B.S. in aerospace I went to school with dudes in their 30's and 40's (military vets) and they were able to succeed in getting their degree and compete with their younger peers in the job market. I'm a big advocate of community colleges because that's what I did before transferring to an engineering college.

Last but not least, our Frequently Asked Questions page has a lot of good information on Civil/Structural engineering so I would read some of the responses there to get a sense of what engineers do for work. Even though you've had some exposure to engineering, there's quite a bit of job variety and you should investigate what direction you want to head before doing it.

If you have any followup questions, the users here and in r/engineering are more than happy to answer them.

Well the whole field of what you are delving into is categorized as Kinematics and Dynamics, which is enormous.

​

There are very many types of mechanical devices designed by various people throughout the world which can accomplish what you need.

​

Many of them could be applied to your system and only you can fully determine what the "best" one is, depending on your requirements.

​

This is a nice book to look through for ideas:

​

https://www.amazon.com/Mechanisms-Mechanical-Devices-Sourcebook-5th/dp/0071704426/ref=sr_1_1?crid=2CRBTTO3RT6RC&keywords=mechanisms+and+mechanical+devices+sourcebook&qid=1557683532&s=gateway&sprefix=mechanisms+and+mechanical+%2Caps%2C143&sr=8-1

​

As far as calculating things, it's extremely difficult without some knowledge of math and a little experience in applying said math to your design. This is pretty hard to do without formal education of at least the basics of these fields.

​

For example, do you know how to isolate the elements of your design and draw a free body diagram of each of them, without making logical errors (which are pretty easy to do by the way).

​

This is a basic engineering design method you need to use to perform calculations on your proposed designs. I don't think it could be well explained through a forum post. It would go much faster by having somebody help you out in person, or if you can do this, pick up an engineering book and read the relevant sections carefully so you understand them enough to apply them. This tool is initially learned in the fields of Statics, so you'd need a Statics book first. Then you'd need a Kinematics and Dynamics book to determine forces due to acceleration.

​

Looking briefly at your design, my first impression is that it can work. However, make sure that the linkage attached to the servo and the push rod and control horn never fully go parallel to each other. If that happens, you have no guarantee that the mechanism will return to its original proper position.

​

I can explain with a very disturbing analogy. Imagine your elbow can rotate 180 degrees so you can bend your arm backward fully, and for our sake, lets also imagine that this is totally normal and is not damaging.

​

Now imagine you are holding your arm straight against a wall so that the two linkages of your arm, the (1) forearm part and (2) bicep part are in alignment.

​

When you push against the wall, will your arm bend one way, or the other way? The arm has three options, depending on minute and uncontrollable differences: (1) If the force is perfectly horizontal your arm will not move at all and will continue to push against the wall (2) the forearm moves "up" and bends as normal and (3) the forearm moves "down" and bends backwards.

​

The same will happen in linkages if the they all line up. Since we want the linkage to always move the way we want it to move, we have to prevent this special position form occurring.

​

That's a common problem that people who have never designed linkages easily run into.

I have two recommendations:

http://www.amazon.com/Differential-Equations-Scientists-Engineers-Mathematics/dp/048667620X/

This is an excellent survey that saved my bacon as a physics BS student transitioning to graduate PDE in math. The text is clear and divided into easily consumable lectures. It's also available for $10, a bargain.

http://www.amazon.com/Partial-Differential-Equations-Action-Universitext/dp/8847007518

This is the book I would recommend as a "second pass" through PDE. If you pursue the subject as a graduate student, this will give you information necessary as you transition to applying real analysis and basic functional analysis ideas to solving PDEs. It has a very holistic approach, but uses a lot of ideas and tools that I didn't see until graduate school. It's a great self-study (but definitely higher level than Farlow), and would be an excellent book to convince your graduate level PDE teacher to give a two semester course from(assuming they were of a more cooperative disposition).

I'm not sure what's specifically standard for those types of applications and what sorts of cases are run, but industry standard changes a lot even in single industries.

CFD is often the long pole in the tent because of the plethora of assumptions made on the flow physics. We don't have computers fast enough to resolve everything easily so generally engineers use lots of models which don't always work. Good boundary condition data is often hard to come by, complex geometry is hard to mesh well, and you end up in a position where lots of subtle things can make everything go wrong.

It sounds like you're doing a sort of aero analysis, which often are very costly computationally because the mesh requirements are so large. If you want to buy hardware you're looking at $2-3k minimum in equipment to get the job done very slowly. Which doesn't include the software, if you want a commercial package those are very, very costly, typically far outside hobbyist range. Open-source packages exist but you have to be willing to put a lot of effort into them, since they often lack good documentation and training. You may be able to limit the size of the case to save yourself computational cost, but then see my comment about assumptions above.

If your work has a commercial package onsite that you're allowed to play with on company hardware this is your best entry route. The two most common packages are Fluent from ANSYS and STAR-CCM+ from Siemens PLM. They will have good documentation and step-by-step tutorials.

If you really want to delve into things yourself, you can download OpenFOAM, which is an open-source package. It has a steep learning curve, but tutorials exist with varying quality on youtube and elsewhere.

CFD is not really something to jump in to without learning theory, though. I would recommend you pick up a book or two. My recommendation for your sort of scenario would be this one: https://www.amazon.com/Introduction-Computational-Fluid-Dynamics-Finite/dp/0131274988 though you may be able to find PDF copies on the internet. You really need to learn what the buttons do before you press them, else you can easily land yourself in a position with good-looking pictures that are nonsense.

Introduction to Robotics: Mechanics and Control by Craig (http://www.ashkanheydarian.com/images/introduction_to_robotics_mechanics_and_control_3rd_edition.pdf)
That will get you a good reference, good explanations of transformation matrices, etc. Examples and exercises use Matlab, which is pretty standard in industry for robot control development, at least in R&D. If you use python instead, its pretty easy to go back and forth.

If you can find a cheap copy of http://www.amazon.com/Ingenious-Mechanisms-Designers-Inventors/dp/0831110848, get it, its a pretty cool book. You can also google things like this, so it isn't essential, just a nice to have. When you are trying to figure out how to get a certain motion, chances are someone has already figured it out and you don't need to re-invent.

It is also essential to understand, on a deep level, how any sensors and A/D hardware you are using works. Always be very careful to make sure you are measuring what you want to measure and what you think you are measuring. I don't have any good books for that, but the interwebs are good for researching sensors and wikipedia's entries on A/D conversion are good.

r/robotics
r/mechatronics
r/mechanicalengineering
r/ECE
r/arduino
etc...

On the home hobby side, you can always get into Arduino and/or raspberry pi projects. There are a ton of kits, open source hardware, and open source software available for both. When you get a job, budget for side projects :)

I do highly recommend Genome by Matt Ridley and A History of God by Karen Armstrong. It looks like Before the Big Bang might be a great idea too.

However, I'm noticing a bit of redundancy in your stacks and don't want you to get bored! In the presence of the other books, I would recommend Dawkins' The Ancestor's Tale in lieu of The Greatest Show on Earth. (Although, if you're actually not going to read all the other books, I would actually go the other way.) Similarly, I would probably choose either to read the God Delusion or a few of the other books there.

Other recommendations: how about The Red Queen by Matt Ridley, and The Seven Daughters of Eve by Bryan Sykes? These occupy niches not covered by the others.

The popular expositions on cosmology all look supremely awesome, but you should probably choose half of them. Another idea: read just The Fabric of the Cosmos by Greene, and if you love it, go ahead and learn mechanics, vector calculus, Electrodynamics, linear algebra, and Quantum Mechanics! Hmm...on second thought, that might actually take longer than just reading those books :)

I heard good things about it, but honestly as an applied mathematician I found its table of contents too lackluster. Its coverage appears to be in a weird spot between "for physicists" and "for mathematicians" and I don't know who its target audience is. I think the standard recommendation for classical mechanics from the physics side is Goldstein, which is a perfectly good book with plenty of math!

For an actual mathematicians' take on classical mechanics, you'll have to wait until you take more advanced math, namely real analysis and differential geometry. Common references are Spivak and Tu. When you have that background, I think Arnold has the best mathematical treatment of classical mechanics.

The mixing part is the same. If you are solely the FOH mixer, and you don't want to be in charge of the bigger picture, you have no concerns - just make it sound good and know the consoles you are working on. The system tech is there to make sure that the rig sounds good everywhere in the room, and the PM and riggers are there to make sure it is run and hung safely and efficiently.

If you want to PM on bigger rigs like that, you need to start learning the details of all those people's jobs - not necessarily so you can tell them what to do, but so that you can spot safety issues and inefficiencies, and work hand-in-hand with them to meet your goals.

Here's a good book to start on power: https://www.amazon.com/Electricity-Entertainment-Electrician-Technician-Richard/dp/0415714834

And here is a good book on audio systems: https://www.amazon.com/gp/product/0415731011/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1

I haven't read this one on networks yet, but it's probably my next read...maybe others can chime in on wether it is a good one.

https://www.amazon.com/Show-Networks-Control-Systems-Entertainment/dp/0692958738/ref=asc_df_0692958738/?tag=hyprod-20&linkCode=df0&hvadid=312115090752&hvpos=1o1&hvnetw=g&hvrand=449842820588414772&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9061129&hvtargid=pla-415287733133&psc=1

​

And of course, nothing beats experience, so weasel your way into bigger jobs and watch what everyone is doing.

​

Absolutely. Thermodynamics and Kinetics are two massive fields in materials science and chemistry that are used to determine rates of growth, shape, and more. Crystal growth depends on a slew of things including temperature, concentrations, size of atoms, free energy, entropy, enthalpy, and more.


For example, a TTT diagram (temperature, time, transition digram) can be used to determine the crystalline phase of a material when cooling from a melt with some cooling rate: http://www.sv.vt.edu/classes/MSE2094_NoteBook/96ClassProj/examples/kimttt.html





Of course, doing it by hand would be pretty hard, but modeling has become much more prevalent over the past decade. For example: http://psoup.math.wisc.edu/papers/h3l.pdf

If you want an excellent book on the subject, I wholly recommend this book right here: http://www.amazon.com/Transformations-Metals-Edition-Revised-Reprint/dp/1420062107

This is the book I used in my phase transformations class and it's one of the best texts I have ever read

you may be able to find an older edition for cheaper, or simply get the international edition for ~$25: http://www.alibris.com/Phase-transformations-in-metals-and-alloys-David-A-Porter/book/5096543?matches=55


--------------------------------------

and I just realized after writing this that you probably wanted more in a earth science context. Nonetheless, the ideas from materials science and chemistry remain the same, even in earth sceinces

https://en.wikipedia.org/wiki/Affine_transformation

https://www.math.tamu.edu/~stecher/LinearAlgebraPdfFiles/chapterThree.pdf

https://www.khanacademy.org/math/linear-algebra/matrix-transformations/linear-transformations/v/linear-transformations

A linear time-invariant circuit system is a linear system. You can represent it as a linear matrix - which is what SPICE does to solve circuits: V = Z I or I = Z^(-1) V.

An affine transform is merely a form of linear matrix transformation that has particular constraints on its elements that cause it to be "affine". Without more information this makes no sense to do on a circuit but maybe there's a case I don't know about.

There are issues with general circuit representation in this form so systems like SPICE do NOT use these in this form but in a combined matrix form (so you can have zero or infinite values of V or I or Z without blowing things up).

A really, really amazing book on linear transformations and how they tie to complex math is Tristan Needham's Visual Complex Analysis.

If you've ever been fascinated by circuit theory with regards to linear algebra, Fourier transforms, Euler's Identity, Stability Analysis, etc., and wanted to understand the underlying math better, this is the book to read. It's easy to read but has plenty of rigor. Also highly relevant to graphics transformations used in GPUs.

Climate scientist Michael Mann criticizes several of the claims in the article as overstated in this facebook post, though like most scientists he agrees with the general point that the consequences of climate change will be dire unless we take serious action (he has a book for non-scientists outlining the dangers and the politicization of the issue, The Madhouse Effect). And if anyone's interested in a book focused specifically on the best scientific predictions about the consequences of various amounts of warming, you could check out Six Degrees: Our Future on a Hotter Planet (see this post from one of the climate scientists on the realclimate.org blog, which gives it a positive review and says it accurately reflects the scientific literature on future scenarios).

I think our best chance of avoiding disaster lies in some combination of moving over to renewables and/or nuclear within the next few decades combined with massive production of carbon capture devices in the second half of the century, which could allow us to keep the warming to around 2 degrees or less. One important point is that without such massive deployment of carbon capture we don't really stand a chance of keeping it that low--check out the graphs here where the first two graphs show how fast carbon emissions would have to go to zero without any carbon capture if we want to keep warming to 1.5 degrees or less, along with a third graph showing how the decline can be more gradual if we have negative emissions later. The graphs are based on the "carbon quotas" for different amounts of warming on p. 64 of this IPCC report, and the quota for 2 degrees is not that much larger than 1.5 degrees (2900 gigatons vs. 2250 gigatons, only 29% larger) so the corresponding graphs for keeping it under 2 degrees wouldn't look too different.

The cause for hope here is that prototypes for carbon capture devices that remove CO2 much more efficiently than trees have already been built, see this article and this one, along with this interview with a physicist involved in the research where he makes the following point:

>My hope would be that we then would have a device that can take out a ton a day of carbon from the atmosphere. If you take out a ton a day, you would need 100 million air capture devices to take out all the C02 that we putting into the atmosphere today. And I would argue that it would be a lot less than that because we would also be capturing carbon at the flue stack, and not making the C02 in the first place by developing solar and wind technologies. ... There are about 1 billion cars out there. We are building 70 million cars and light trucks a year. So that kind of industrial production is quite possible. Eventually we should be able to produce an air capture device for roughly what it costs to manufacture a car.

I also think that another reason to be hopeful is that we may in the not-too-distant future achieve full automation of the production process for most mass-produced goods, leading to the possibility of self-replicating robot factories (what Eric Drexler calls clanking replicators), and I think the effect of this would tend to drive down the prices of all mass-produced goods--including things like carbon capture devices and solar panels--down to barely more than the cost of the raw materials and energy that went into them, so large-scale production of any good would be much cheaper. I talked more about this idea here.

Im a sophomore EE but I love books. Check out
Code
as well as classic physics books such as Theory of Relativity.
And a solid up to date formula handbook

and then specific books to your sub-field/concentration. I worked at a library and Barnes & Noble for a few years, and I highly suggest just living in the science department there when not at school and find books you love.

Complex analysis, my friend. If you can understand even the basics intuitively it can smooth out a lot of the higher classes. I like Needham's Visual Complex Analysis but I've been told it's not a good introduction. I'm not really sure what would be, but you might want to look at Introductory Complex Analysis by Silverman (Dover books are cheap and awesome).

Graph theory certainly wouldn't be too bad either. It's actually pretty fun and has applications in programming and algorithms. Dover publishes this book which I expect would be excellent to read at work (pretty basic, moves slowly). Same goes for linear algebra if you can find a book on it (look for one with "matrix analysis" in the title).

Learning advanced set theory or category theory will probably not be useful at all. (*ducks*).

The overall goal of system optimization is to reduce variance over the space. That is, we want everyone in the audience area to hear the same show, with the same spectral (tonal) balance, at the same level.

The audio analyzer is a tool that plays a major role in that process, but it is primarily a matter of being able to diagnose problems and knowing how to fix them.

I wrote this post to explain the different types of audio analyzers and each type's strengths and weaknesses. Of those you mention, all are dual-channel FFT platforms, with the exception of Room EQ Wizard, which is a TDS system. Those terms are explained in the post. Rita and REW are freeware. Smaart and Systune are relatively expensive tools but both offer a free 30-day trial. If you understand the principles of measurement theory and how to read the analyzers, you can "get there" will all of them, because the underlying math is the same. It just comes down to feature set and a workflow you find comfortable. I would advise not making a purchase right away until you've had some experience with the tools, to prevent yourself wasting a lot of money on something you don't like or won't use.

In terms of resources:

• The Smaart v8 manual [PDF] is probably the most well-written and least mathematical overview of all the concepts of measurement theory.
  
• Here is a one-hour webinar that goes through the whole concept, although it moves kinda fast.
  
• I have a series of articles here that goes through some measurement theory and applications.
  
• This book by Bob McCarthy is the current industry-standard resource. It is not a light read but is a good representation of the current state of the field.
  
  Hopefully that is enough to get you started. I am happy to answer any questions. There are also many practictioners in r/smaart and r/livesound who can jump in and offer their thoughts as well.

A wonderful source for those that want to know questions better: Naive Lie Theory by John Stillwell

(Google excerpts)

This book is a wonderful read and it jumps into quaternions very early on. It really helps one learn about them and other spaces. Is also a remarkably Easy to access book on Lie Theory — (basic calculus, linear algebra only real read. Having seen group theory before is nice, but not necessary)

I’m about half way through and just love it.

Also, somewhat related, Visual Complex Analysis by Tristan Needham is a ridiculously good and powerful book.

(Google excerpts)

Anyone that has to interact with complex numbers should read at least the first two chapters in my opinion.

Your post has too little context/content for anyone to give you particularly relevant or specific advice. You should list what you know already and what you’re trying to learn. I find it’s easiest to research a new subject when I have a concrete problem I’m trying to solve.

But anyway, I’m going to assume you studied up through single variable calculus and are reasonably motivated to put some effort in with your reading. Here are some books which you might enjoy, depending on your interests. All should be reasonably accessible (to, say, a sharp and motivated undergraduate), but they’ll all take some work:

I really enjoyed "Rocks Don't Lie: A Geologist Investigates Noah's Flood", which I don't think I've ever seen mentioned here (I only heard about it myself because it was a local author).

It's been a while since I read it, but what I remember enjoying was how the religious beliefs of our earliest geologists influenced their understanding of what they were discovering in the field. The early explorers set out to find evidence for Noah's flood, so it was amusing seeing them trying to wrap their heads around things like finding mammoths in Siberia, that were obviously washed away in the deluge!

I've not read it myself, but I really enjoyed the Your Inner Fish documentary series and have been reading to pick this one up.

Shigley is good. Free if you google hard enough.
Machinerys Handbook is the Bible( get an older edition or e-version to save money). Might be able to fing it free online with good enough google-fu.
These are great too Ingenious Mechanisms: (Four Volume Set) (Ingenious Mechanisms for Designers & Inventors) https://www.amazon.com/dp/0831110848/ref=cm_sw_r_cp_apa_i_JKLzCbREGJJW9
Again get used or e-version.

A few degrees warmer is about how much we can stand. So, with that few degrees comes at least a few feet of sea level rise, likely more. So coastal areas that tend to be the highest populated, are going to need to retreat from the coast. That's going to be a huge economic burden. How is that burden born? Best left to economists I suppose....

Also, California and the west will tend to get drier, which will affect agriculture and I would venture agricultural costs. The mid-west is also slated to become drier, this is at a time when the Ogallala aquifer is being sucked dry, so we are going to be running out of a pretty precious resource in large chunks of the US. Further abroad, with melting glaciers hundreds of millions may be left without water. The middle east is supposed to also dry up. This is likely to create a humanitarian crisis.

There could be significant changes in disease distributions as well. With things like malaria, Zika, etc. becoming more prevalent in the US because of a spread of their vektors (e.g., certain tropical mosquito species).

Depending on the severity, much of the Amazon rain forest may dry out, though there is some good debate around that topic. Coral reefs laregly won't be able to keep up, which could crash some fisheries and ecosystems. Forest diseases may be more prevalent (e.g., emerald ash borer in the eastern US that is wiping out ash trees), and extinction rates are thought to spike, with 20-30% of species at risk of extinction.

Check out a book 6 degrees. I haven't read it yet, but it's on my wish list - supposed to be a good run down of the catastrphe that 6 degrees of warming will bring - basically an end of civilization as we know it. Some respected scientists think that the population will end up crashing to 1 billion in the next century..... that will cause some chaos...

The Mis-Education of Mathematics Teachers made a huge impression on me, in particular its emphasis on content knowledge and the fundamental principles of mathematics. More recently, the following comment by Ian Stewart has persuaded me to put more emphasis on the visual aspects of the subjects I teach:

> One of the saddest developments in school mathematics has been the downgrading of the visual for the formal. I'm not lamenting the loss of traditional Euclidean geometry, despite its virtues, because it too emphasised stilted formalities. But to replace our rich visual tradition by silly games with 2x2 matrices has always seemed to me to be the height of folly. It is therefore a special pleasure to see Tristan Needham's Visual Complex Analysis with its elegantly illustrated visual approach. Yes, he has 2x2 matrices―but his are interesting. (Ian Stewart, New Scientist, 11 October 1997) (source)

At least read Why your first speaker should be a proven design. If your goal is not to embark on speaker design as a hobby, but to build one pair of kick-ass speakers for personal use, build a kit.

Now if your goal is to learn speaker design, go for it. Here's a book that's frequently recommended. This is a "read a book" topic, not an ask on Reddit and then do some google searches topic.

I'd like to suggest that you go with an active crossover. A miniDSP will allow you to do a lot of tweaking of your crossover without spending a ton of money on different passive components that you won't use. Once you have finalized on something you like you can always build a passive equivalent and use the miniDSP for your next project.

Ok, here's a list of books that might interest you.

• [Introductory Mining Engineering] (http://www.amazon.com/Introductory-Mining-Engineering-Howard-Hartman/dp/0471348511/ref=sr_1_1?s=books&ie=UTF8&qid=1412111081&sr=1-1&keywords=introductory+mining+engineering) as others have mentioned is a good, not too technical introduction to mining engineering and the industry as a whole.
  
  
• [Mining Explained] (http://www.smenet.org/store/mining-books.cfm/Mining-Explained%2C-11th-Edition/9041) is a good little overview of the industry, I believe it was written as an introductory guide for investors.
  
  
• [The Deep Dark] (http://www.amazon.com/The-Deep-Dark-Disaster-Redemption/dp/0307238776) is about the Sunshine Mine disaster. It is a well written book that reads like a novel. It gives a good overview of hardrock mining techniques in northern Idaho, but is more focused on the people, the disaster and the recovery efforts.
  
  
• [The World of Mining] (http://www.amazon.com/World-Mining-Richard-Woldendorp/dp/0415671892/ref=sr_1_1?s=books&ie=UTF8&qid=1412111733&sr=1-1&keywords=the+world+of+mining) is more of a photography book, but it has a lot of great contemporary pictures from mines around the world.
  
  
• [Deep Enough] (http://www.amazon.com/Deep-Enough-Working-Stiff-Western/dp/0806125292/ref=sr_1_1?s=books&ie=UTF8&qid=1412110097&sr=1-1&keywords=deep+enough) is the memoir of a man from an affluent New York family that decides to go to the western US in the early 1900's, where he ends up working in mining. This is a good one if you're interested the culture of a 1900's mining camp as well as the technical aspects.
  
  
• [Trapped] (http://www.amazon.com/Trapped-1909-Cherry-Mine-Disaster/dp/0743421957) is about the 1909 Cherry Creek mine disaster at a coal mine in Illinois.
  
  
• [The Making of a Hardrock Miner] (http://www.amazon.com/making-hardrock-miner-experiences-molybdenum/dp/0831071168/ref=sr_1_1?s=books&ie=UTF8&qid=1412110431&sr=1-1&keywords=the+making+of+a+hard+rock+miner) is similar to Deep Enough, but written in the 1970's.
  
  
• [Mines, mules and me in Mexico] (http://www.amazon.com/Mules-Mines-Me-Mexico-1895-1932/dp/0816506264/ref=sr_1_1?s=books&ie=UTF8&qid=1412110933&sr=1-1&keywords=mines+mules+and+me+in+mexico) similar in style to Deep Enough, it was written by a mining engineer that was working in Mexico before and during the Mexican Revolution.
  
  
• [Grasberg] (http://www.amazon.com/Grasberg-richest-deposit-mountains-Indonesia/dp/0965289001) is a historical account of the discovery and development of the Grasberg mine in Indonesia.
  
  
• [The Roar and the Silence] (http://www.amazon.com/The-Roar-And-Silence-Shepperson/dp/0874173205) is a historical account of Virginia City, Nevada which was the most advanced and affluent mining camp of its day. It follows Virginia City from a gritty mining camp, to a city whose influence rivaled some of the biggest cities of its day, through its slow fade into obscurity.
  
  
• [Out of the Fiery Furnace] (http://www.amazon.com/Out-Fiery-Furnace-History-Mankind/dp/027100441X/ref=sr_1_1?s=books&ie=UTF8&qid=1412110707&sr=1-1&keywords=out+of+the+fiery+furnace) is a look at how world history was shaped by mankind's discovery and utilization of different metals. It discusses how mining techniques have evolved over time.

I don't have any PDFs, but here is a good one you can get for pretty cheap. I used it as an undergrad and still refer back to it.

You might also try this Dover book.

Hope that helps.

I recommend reading books. I personally work a very difficult engineering job, where I'm under-educated for the tasks I'm given (it's a startup company). So I just keep buying books, and read them constantly. 30 minute carpool? Flip through a textbook and see what catches my eye. I think it's important to find it interesting, otherwise it would become unbearable to study that much, after college. I have a total hard-on for engineering, so I get excited about a textbook I just ordered on Amazon from my own paycheck, and can't wait for it to show up.

Engineering Formulas

Engineer to Win

Aircraft Structures

These are a handful of examples of books I just pick up and browse through regularly. "Engineering Formulas" is very dense obviously, I just flip through it randomly, and go "ohhhhh yeah yeah, I forgot about that equation/concept from school", which prompts me to hit up Wikipedia (please donate!), then maybe buy a related book. "Engineer to Win" is geared towards race car engineering, but it's 90% structures/bolts/metallurgy, and I apply nearly all of it into aerospace easily. It's a GREAT read too, the guy is a salty old bastard that swears mid-paragraph during a technical explanation, I find it hilarious.

I highly recommend Ingenious Mechanisms for Designers & Inventors by Franklin Jones. It's about $120, but it is a four-volume set of hardcover books. I have it and I love it.

While you're on that page check out the "frequently bought together" links, there are some interesting titles there. I haven't actually read any of them, but they look interesting.

While Anderson's book is pretty good, I wouldn't recommend it in this case. He writes primarily from an aerodynamics view, with the assumption that the Mach number will be important, and deals mainly with density based solvers. None of that is going to be relevant to most hydrodynamics situations. I would instead recommend something that focuses more on pressure based solvers and low Mach number flows, like Ferziger & Peric, or Versteeg & Malalakesera if you want something that is a bit more of a hand book. I find Ferziger & Peric especially helpful for dealing with OpenFOAM because so much of the terminology is similar.

To add to this, always have a personal goal of improvement. Something about yourself you are improving.

The easiest thing to do is study for your job or future job. Once a week should be spent improving your professional life. This could mean going to conferences, seminars, or society meetings, but it could also simply mean sitting down and reading "Never Eat Alone" before going to bed.

The monotony of work isn't so bad when you can look back every month and know you are better than you were.

For example, my last goal was "Lose 25 pounds", I did it in a couple of months. The goal before that was "Buy a house." My current goal is studying a specific book for work. The next one is improving my handwriting.

The thing about the goals though, is they cannot simply be thrown away, they must be things that stay with you. So here are my goals again, but with small things that stick with me:

1. Buy a house and improve it.
   
   
2. Lose 25 pounds and keep it off.
   
   
3. Study this book and continue to study at least once a week.
   
   
4. improve my handwriting and don't regress.
   

Congratulations are in order, to you as well as lysa_m, shizzy0 and all the other helpful redditors here. It must feel really great to get over this hurdle!

I just wanted to add a link to the book of Tristram Needham, Visual Complex Analysis. As lysa_m pointed out, you are not the first person in history to find "imaginary" numbers baffling. You can read the first 5 or 6 pages of Needham's book online at the Amazon page above. There he outlines the history of the subject and explains some of the same points made in the comments here.

Check out what your local university or college has listed for their physical geology text book(s), visit their book store and see if they fit the bill. A very useful book for identification, surprisingly, can be in the form of a lab book as well. If those are too costly, perhaps they would make a good future investment or you can find them online as pdf's, or e-books. In the mean time, there are also plenty of field guides, for example that may interest you, or even that you can print out (pdf) for basic identification.

There are some great suggestions here, and I would include The Rocks Don't Lie.

It does a great job recounting the history of geology as the science evolved, and how it affected culture. I different take than the other suggestions, but certainly relevant and well worth the read.

The author is a well known geomorphology expert.

I can't give you numbers, although others have made such attempts. There is a book available called Six Degrees that attempts to describe the impacts of climate change over 100 years at different levels (1 degree C change; 2 degree C change; etc.). It has numbers, although I can't suggest how accurate they are (those kinds of numerical forecasting exercises are virtually impossible to do with accuracy in complex systems).

Another pop-science but seemingly sound exploration of likely effects (and current conditions) is Hot, Flat, and Crowded by Friedman. It definitely has a "position," but it is a good qualitative place to start if you want an entryway into global environmental change dynamics.

Book of proof is a more gentle introduction to proofs then How to Prove it.

​

No bullshit guide to linear algebra is a gentle introduction to linear algebra when compared to the popular Linear Algebra Done Right.

​

An Illustrated Theory of Numbers is a fantastic introduction book to number theory in a similar style to the popular Visual Complex Analysis.

tl;dr: you need to learn proofs to read most math books, but if nothing else there's a book at the bottom of this post that you can probably dive into with nothing beyond basic calculus skills.

Are you proficient in reading and writing proofs?

If you aren't, this is the single biggest skill that you need to learn (and, strangely, a skill that gets almost no attention in school unless you seek it out as an undergraduate). There are books devoted to developing this skill—How to Prove It is one.

After you've learned about proof (or while you're still learning about it), you can cut your teeth on some basic real analysis. Basic Elements of Real Analysis by Protter is a book that I'm familiar with, but there are tons of others. Ask around.

You don't have to start with analysis; you could start with algebra (Algebra and Geometry by Beardon is a nice little book I stumbled upon) or discrete (sorry, don't know any books to recommend), or something else. Topology probably requires at least a little familiarity with analysis, though.

The other thing to realize is that math books at upper-level undergraduate and beyond are usually terse and leave a lot to the reader (Rudin is famous for this). You should expect to have to sit down with pencil and paper and fill in gaps in explanations and proofs in order to keep up. This is in contrast to high-school/freshman/sophomore-style books like Stewart's Calculus where everything is spelled out on glossy pages with color pictures (and where proofs are mostly absent).

And just because: Visual Complex Analysis is a really great book. Complex numbers, functions and calculus with complex numbers, connections to geometry, non-Euclidean geometry, and more. Lots of explanation, and you don't really need to know how to do proofs.

Lindeburg book is very good. Also use the NCEES practice exam. Lucky you that geotech is a big portion of the exam. For extra help on cross over topics like math, stat, statics, dynamics, economic, mech of mats, materials, ethics you can use mech/other discipline books to get more review.

Jeff Bagby has a good excel spreadsheet with baked-in formulas. However, it's difficult to use unless you have a good base understanding of what you're doing. Some good books to get you started are the Loudspeaker Design Cookbook and Speaker Building 201.
Keep in mind that it is absolutely necessary to have measurement equipment if you want to design anything and be able to point out what is wrong. Even if you have perfect pitch, actually quantifying what you're hearing in a speaker is really hard to do, and honestly can probably only come from lots of experience listening and then measuring to be able to recognize what is off.

Still, I recommend you just build an existing design.

The popular books seem to be:

• Lindeburg FE Civil Review Manual
  
• Lindeburg FE Civil Practice Problems
  
• PPI FE Civil Exam Prep Workbook (600 Q and A)
  
• Anthem Publishing FE Civil Practice Exam (110 Q and A)
  
  Lindeburg FE Review Manual: nice if you want short concise information about each subject and topic. I hear the practice problems book are a bit harder than the exam but good prep all the same.
  
  PPI 600 Q and A: I've been using it and like it but having the solution directly under the question makes it cumbersome trying to not see the answer when you the flip the page. Still a decent book but there are some mistakes.
  
  Anthem Publishing Exam Book: seems similar to the NCEES Practice Exam. I bought it cause it was recommended and I wanted a another practice exam.
  
  Bottom line the FE Reference Handbook 9.4 from NCEES, knowing your calculator, and a couple practice question books should get you where you need to be.

0.005" is a standard engineering tolerance, it is by no means "incredibly precise", you can do that with a WWII bridgeport.

An excellent resource for mechanisms of all sorts: http://www.amazon.com/Ingenious-Mechanisms-Designers-Inventors/dp/0831110848

Perhaps a local library would have one you could take a look at?

Failing that, there a lot of considerations going into a cam design. The acceleration of the follower is important. Having a ramp like you have drawn will make the follower want to skip off the cam at high speeds. You want to have smooth acceleration of the follower by having gradual ups and downs.

It would be easier to help with more information. How many followers are there? How fast does it need to go? How long does it need to last? What forces are involved?

As it stands the design you have posted would work with a roller follower and at slow speeds.

Someone mentioned 507 movements which is really good. Also if you want something a little more detailed, the book Ingenious Mechanisms is pretty good as well.

Here's my rough list of textbook recommendations. There are a ton of Dover paperbacks that I didn't put on here, since they're not as widely used, but they are really great and really cheap.

I've glanced through Taylor and it is a bit low, but I might give it a chance again. I was thinking of a book like http://www.amazon.com/Mathematical-Classical-Mechanics-Graduate-Mathematics/dp/0387968903 but it's too mathematically sophisticated for me right now. Any other recommendations for a grad level book?

What book have you been using? My undergraduate course is using Brown & Churchill, which a lot of people seem to really like, and I've also heard really great things about Tristan Needham's Visual Complex Analysis and I've loved what I've seen of it (mostly just the chapter on winding numbers and the argument principle from a geometric viewpoint).

What is the square root of i? If it takes you longer than .5 seconds to figure this in your head, you are blind.

You need to read visual complex analysis by Tristan Needham. This book utterly opened my eyes to what complex number actually are (hint: The correct question is "what is multiplication?"). I used to be mystified by them, as you are. No more. They are as unmystical as anything in math. I also gained a supreme ability to use them, in practice. Read the book, and you will join the ranks of the enlightened.

Pick up the book Visual Complex Analysis by Tristan Needham. You can probably find a free copy online, but this one is, I assure you, worth every penny. Not only is it the most intuitive book on complex analysis ever written in my opinion; it is probably among the very best mathematical books in general.

Let me put it this way. I happened upon that book in high school and was so captivated that I read it cover to cover. Upon entering college, my understanding of the subject was so strong and intuitive I could jump into graduate-level complex analysis with little to no difficulty.

This book is really great for mixing. Currently making my way through it. It is very dense and thorough


This book has been recommended to me a lot for mastering. A very good producer told me this was the standard for wanting to learn proper mastering techniques. I haven’t read it yet

A book about the history of fraud, treachery and thieves in the industry can be found here:A hole in the ground with a liar at the top

There's also another title that tells more stories about the workers in artisan diamond mining: Diamond a journey into the heart of an obsession

As far as books that get more technical, Introductory Mining Engineering would be a good start.

If the business and economics are more what you're interested in, a quick google search for "mining white papers" should yield a whole pile of results. Most of them being written by some consulting houses such as E&Y, KPMG, McKinsey, et al.

Let me know more what you're looking for. Mining Engineer here who loves to read. =)

Hi Alex. As far as dividing my time, I really just read the question over and then decided the likelihood I could solve it in a minute and a half. If I knew where the equation was for it in the manual and I knew that the math was straight forward I would just do it. If not, I would try to solve it quickly and if I couldn't I would mark it to solve at the end.


As far as solids and HW:

  This one is expensive and very small in size. It consists of two practice exams and a brief explanation of the formulas used. It wasn't really a good tool to learn new material, but it has some good solid questions in it. I would suggest taking this timed and give yourself ~2 mins per question with only your manual to try and solve it. the biggest problem in studying for the environmental one is that there is so few resources available.
  
  I also just saw this:

  They are both new and I don't know anything about them, but they may be worthwhile if you check them out.
  
  
  

An Introduction to Ordinary Differential Equations - $7.62

Ordinary Differential Equations - $14.74

Partial Differential Equations for Scientists and Engineers - $11.01

Dover books on mathematics have great books for very cheap. I personally own the second and third book on this list and I thought they were a great resource, especially for the price.

You have rolled the high pass up to 335Hz @ 12dB per octave. Good, Let's get that whole low end spectrum out of there!

Next, you have a 9dB cut at 300hZ, just in case that roll off to 355hz didn't cover it all.

You are, at this point, either mic'ing Darth Vader ,Marsellus Wallace, or a Moog but want none of that "Anything below 1kHz" spectrum. You have taken the rumble, the low end, the woofy and the honky-ness out of their voice.

Next you have a couple of notch filters at a 6 & 9dB reduction with a tight Q, probably to stop feedback. I'd imagine you pulled these back this far to make sure you had no feedback problems. I'd bet -3dB would work just fine. If it is for tone shaping and not feedback problems, you really aren't hearing that result due to the tight Q.

Lastly, you have a 9dB boost, 9 friction' Decibels! Holy hell, does this guy sing in to a pillow as a pop filter? 9 dB's, maybe a little bit of overkill. Oh who am I kidding, 9dB's of gain is total overkill or your mic is a piece of crap.

I could try to explain to you why you are most likely having to gain up the mic, why were pushing the fader to +8, just trying to get it in to the mix but what I'd really love to explain is how you ruined the phase of this signal. I'd also imagine that if you had 3 more sets of PEQ that they would also be fully engaged, knocking out more pesky frequencies.

Maybe your FOH / Monitors graph is all pulled out or not being used at all, I could see either happening here.

Problems I see:

• You are trying too hard with this channel, you really are!
  
  
• Over EQ'd to say the least
  
  
• Signal is shot to hell
  
  
• or your mic sucks.
  
  Solutions:
  
  
• Just go back to flat at this point
  
  
• OK, HPF to maybe 100-120Hz
  
  
• Notch out 350-400hz, medium Q, maybe 2-3dB
  
  
• Don't turn it up until it feeds back and try to fix it, turn it up, if it feeds back, just turn it down a little.
  
  This is my recommendation, my junior engineers have the same situations pop up. Less really is more…usually.
  
  Recommended Reading
  
  
• Sound System Engineering
  
  
• Sound Systems: Design and Optimization
  
  
• The Sound Reinforcement Handbook
  
  The first two are text books to say the least, you will read them, not really understand them, read them again, catch a little bit, put them away, read them again and slowly start understanding it. I have had these books for years and get as much from them each time as a good novel. The third book is super simple but still awesome essential information.
  
  TLDR
  Start over, Turn it down.
  
  Yeah, this is a TLDR, but you really need to read some of this every now and then. Your ears fool your brain, and so can your eyes.
  
  

Thanks, my main interest seems to lie in petrology/lithology, mostly of sedimentary rocks at the moment, so I've been eyeing up a copy of Sedminetary Rocks in the Field once I have some spare cash. =)

Climate change is a matter of degrees, literally, and the big unknown is at what point do we really start to suffer negative consequences.

Scientists and world leaders so far have a consensus that 2 degrees Celsius is safe. Some scientists say it should be even lower, but that's what most of the negotiations are assuming. 3-4 degrees Celsius is likely what's going to happen unless we make some real aggressive moves soon, which will most likely exacerbate some of the things we see already, which are sea level rises, ocean acidification (leading to fish extinctions), melting of the ice caps and glaciers, and weather changes (drought, desertification, melting tundra). 6 degrees is where most people think we're headed if we can't get our act together and there are a whole bunch of hypotheses about what may happen then: http://www.amazon.com/Six-Degrees-Future-Hotter-Planet/dp/1426203853 . Of course, then there's always the risk of runaway climate change, where we reach a point where warming begets more warming: https://en.wikipedia.org/wiki/Runaway_climate_change and we eventually end up like Venus, although that particular outcome is still up for debate.

So to your point, is this all a futile exercise? I'm not sure we can hit 2 degrees, honestly, at this point. But if we hit 3, the earth our grand children (speaking as someone without kids yet) will live most of their lives in will most likely be similar to the one we live in and the one our parents live in. If we let it get to 5 or 6, then all bets are off. You might be right that they'll come up with some kind of Manhattan project to solve it, but there's no guarantee.

I'm a climate change natalist - I recognize that civilization is over and humanity might be too. Our grandkids won't have electricity and may not have agriculture. Our great-gradkids may not have enough oxygen. Anyways given the coming crash I had a kid that I'm raising to make it through the bottleneck with good wholesome values intact. I'm raising her competent and co-operative.

If you're feeling down about working retail you should read this book. It's about the expected results of each degree of climate warming. It's 10 years old. The changes predicted here are actually mild compared to the changes we've seen, suggesting that we may be on track for a 4° warmer world (mass extinction, complete desertion of the mid-latitudes, the amazon first burning then drying to a desert, human fight toward the poles, endemic drought throughout asia, most crop-land blowing away as dust). Capitalism can't survive that!!

"If engineering were easy, they would have sent a boy with a note."

Seriously there aren't any shortcuts. Either you learn the fundamentals or you don't. But if you want a really good general reference book, get The Mechanical Engineering Reference Manual


Other useful references:

• The Machinery's Handbook
  
  
• Glover's Pocket Reference
  
  
• Mark's Standard Handbook
  
  In actual practice, unless we are launching things into space or making them fly through the air, a lot of engineering is just picking thinks that we know will work by experience (if a 1" square tube will work let's use a 2") or by consulting with vendors.

I don't think this is quite what you're looking for, but I love this as a reference guide for sed deposits. Not a bad price point for a full colour guide. https://www.amazon.com/Sedimentary-Rocks-Field-Colour-Guide/dp/1874545693

I have these two text books on PDE's

https://www.amazon.com/Partial-Differential-Equations-Bleecker-University/dp/1571460365

https://www.amazon.com/Differential-Equations-Scientists-Engineers-Mathematics/dp/048667620X/

The second book is more of a stereotypical cook-book math text. Idk if that's what you're looking for or not but it's inexpensive anyways and does a good job for its purpose.

The first textbook is very well done and is for beginners. However right now it's on the expensive side but when I bought it it was only 30 dollars. So if you wait a little bit the price may drop.

Also one last comment about the first textbook is that the order of the topics is abnormal. The first chapter does a summary of ODE which makes sense. However the first PDE material in the book covers first order PDE's which in my experience is not normal. Usually when people first learn PDE they learn about the heat and wave equations which are second-order PDE's. Idk if you care but I thought I'd just comment on that.

This what I’m hoping for Christmas if you want to get me it that’ll be great!
Marks standard handbook for mechanical engineers

Marks' Handbook for Engineers - Great specific reference for tolerances and fits, also has good general design "common knowledge", formulas, and practice.

Machine Design by Norton
Theory of Machines and Mechanisms by Shigley
are considered the two bibles on machine design and are common in machine design courses.

Materials Selection in Mechanical Design by Ashby

The Machinery's Handbook is a must have and I assume you already know about this.

Mechanisms and Mechanical Designs Sourcebook is good to help spark ideas or solve problems. There are other books along the same lines.

There's information on tolerancing and machining in The Machinery's Handbook especially. I'm not sure on other resources for those. There are books on manufacturing processes that'll discuss the tolerances capable and design limitations.

> So he can get to the unsolvability of the general degree five polynomials in half a year, so what? In my undergrad algebra course it's taken us 2 and a half months to get there, from axioms.

He was talking about teaching that material to schoolchildren, not university students. I'd say that dictates a different pace.

> The value of concise, direct communication is lost on this individual.

He's an internationally renowned mathematician who is considered a very concise and clear writer. His books Mathematical Methods of Classical Mechanics and Ordinary Differential Equations are universally regarded as masterpieces in their fields.

Yeah, there is a $25 review book with over 100 practice problems and solutions on Amazon that I will be going over this week. I also really need to study some topics like statistics so I may look into getting some review booklets about that topic.

Check this review book out: https://www.amazon.com/Environmental-Engineering-Preparation-Questions-Solutions/dp/1532827237/ref=sr_1_2?s=books&ie=UTF8&qid=1480357826&sr=1-2&keywords=environmental+engineering+fe

I found it on another post from this sub and it has good reviews. For $25 it can't hurt.

https://www.amazon.com/Civil-Review-Manual-Michael-Lindeburg/dp/1591264391/ref=sr_1_1?ie=UTF8&qid=1467983879&sr=8-1&keywords=fe+civil+review+manual

Buy the best condition used one you can find! I got mine for like $75 and it's brand new.

There's an awesome, down to earth explanation of this in the mechanics book by Kleppner and Kolenkow. I really recommend checking it out if you have access to it at a library, etc.

> BTW, that wiki song structure article is a mess

Agreed. I linked to that wiki article without even really looking. Personally, I like the following books that go into a lot more detail in regards to production and EDM:

• Music Theory for Computer Musicians
  
• Composition for Computer Musicians
  
• Harmony for Computer Musicians
  
• Dance Music Manual
  
• The Drummers Bible
  
• Mixing Audio: Concepts, Practices, and Tools
  
• Making Music: 74 Creative Strategies for Electronic Music Producers
  
  All the above are solid books.

Mechanisms and Mechanical Devices Sourcebook might be nice.

Its like a museum of mechanisms. I like the 2nd Edition cover for a "coffee table book".

I don't know if complex analysis is your cup of tea but Visual Complex Analysis by Needham is probably the best math book I've bought in a long time.

That's like asking "how many different ways can you prepare, cook, and present a steak dinner".

One good read if you are curious in the "loud speaker design cook book" https://www.amazon.com/Loudspeaker-Design-Cookbook-Vance-Dickason/dp/1882580109

I remember literally wearing the cover off of that book back in the olden days..:)

> The global temperature is increasing wildly

Define wildly. Since 1975 it's increased by an average of about .15 to .2 ^o C per decade and it's increased about 0.8^o C overall since 1880, with about 2/3 of that coming since 1975. It's probably increasing by a bit more than that now because global emissions keep increasing.

> in a few years many heavily populated areas will exceed "wet bulb" temperature, meaning they will become so hot that it would be impossible for human life to exist there

That doesn't seem to fit Wikipedia's definition of wet-bulb temperature, although I'll admit to being very unfamiliar with the term; do you know in what context McPherson used it?

It would help to know exactly what McPherson's temperature projections are. To me, the notion that the usual projections could render places currently supporting hundreds of millions of people uninhabitable within the next few years, or even decades, is tough to believe without hard numbers to back it up.

If you're curious for other sources, my impressions are based roughly on Six Degrees, by Mark Lynas and Introduction to Modern Climate Change, by Andrew Dessler. I think climate change is definitely capable of causing our extinction eventually, but it would require a lot of inaction on our part, and it would still take several centuries at least.

https://www.amazon.com/Sound-Systems-Optimization-Techniques-Alignment/dp/0415731011

I have not read this edition, but the previous was great.

Watch this video clip, based on actual facts.

My top book recommendation:

Six Degrees: Our Future on a Hotter Planet by Mark Lynas

It paints a picture in a real nice way and serves as a good guide for thinking about various degrees.

As mentioned by /u/extinction6 watch Kevin Anderson.

https://www.amazon.co.uk/Introduction-Computational-Fluid-Dynamics-Finite/dp/0131274988

This book is great for starting out. There are others more suited to aerodynamics but that book is a good starting point.

Like most people here have already said Halliday and Resnick are very good.

If you want something a bit more rigorous and thorough, I recommend An Introduction to Mechanics. We are using both these texts for my first year physics course.

For even more help there's MIT Lectures, complete with practice problems and tests, and Khan Academy.

All this should be more than enough to keep you busy until college.

Thanks, I'm actually currently reading Mixing Audio: Concepts, Practices, and Tools.

Any feedback on what I could do to improve the mix? Did anything sound off in particular?

If you're starting out, I'd start with NASA's Indices for propulsion and aerodynamics to get familiarized with everything.

NASA Propulsion Index

NASA Aerodynamics Index

Once you get into it and have the physics and math foundation you can get into the weeds:

Fundamentals of Aerodynamics

This is more of a reference than a learning tool:
NACA airfoil generator

And then if you get into CFD/simulation An Introduction to Computational Fluid Dynamics and Computational Methods for Fluid Dynamics are pretty good.

I liked this one:
https://www.amazon.com/Environmental-Engineering-FE-Review-Manual/dp/1683380142/ref=sr_1_4?s=books&ie=UTF8&qid=1480357826&sr=1-4&keywords=environmental+engineering+fe

After I finish it, I will work through this one:
https://www.amazon.com/Environmental-Engineering-Preparation-Questions-Solutions/dp/1532827237/ref=sr_1_2?s=books&ie=UTF8&qid=1480357826&sr=1-2&keywords=environmental+engineering+fe

Everyone in my class used the former, and I have heard good reviews of the latter on this page.

This is a good book for you to start: An Introduction to Computational Fluid Dynamics: The Finite Volume Method

You will find the definition of some terms and how the different models work. I think it is important for you to get acquaintance with RANS equations. If I can suggest you one more thing it is to look for an publication of a similar work, even if the focus is different than yours, you can find some tips of how to run your simulations.

One of my sources is the book Six Degrees by Mark Lynas, who reviewed several thousand papers on the projected impacts of climate change, many of them based on geological evidence. That's the one that mentions the 500-year dustbowl. It's extensively referenced.

For a discussion of the paleoclimate evidence, that book is good but the best I've found is Storms of My Grandchildren by James Hansen. He goes into the geological evidence and the physical arguments in detail.

The claims I made are not projections of the future. They're simple accountings of the fossil record. Unless you're the type of person who thinks fossils are a hoax, there's no getting around it. Nevertheless I'm sure neither of these will qualify as "sound" since they don't agree with your opinions, but perhaps someone else will be interested.

I have this book and I love it

https://www.amazon.com/Mechanisms-Mechanical-Devices-Sourcebook-5th/dp/0071704426/ref=sr_1_1?ie=UTF8&qid=1542986124&sr=8-1&keywords=mechanisms

I loved learning newtonian mechanics from Kleppner and Kolenkow link. The problems are creative and interesting, which is something that a lot of mechanics books seem to lack.

I am pretty sure op is talking about the book by Mark Lynas.

SME Handbook

Hartman Book

Used both while getting my Mining Engineering degree. They are both really great for what you want but I would go with the Hartman Book. It's cheaper and does just as well.

I would say don't throw out the baby with the bath water. Yes, in the US, you have some bat shit crazy christians that take a literal view of the bible. Go back in time a century or two to any of the universities that the major churches were sponsoring, and they'd laugh at the suggestion that the bible should be taken literally, even in the theology department. Yes, they tried to view the evidence they had through a prism that presumed the bible was in some way true, but they were willing to reject the idea that each word was litterally true. "The Rocks Don't lie" gives a pretty interesting account of that from a geology perspective https://www.amazon.co.uk/Rocks-Dont-Lie-Geologist-Investigates/dp/0393346242/

​

The Modern Catholic church doesn't reject science. The pope worked in Chemistry, evolution and the big bang are accepted as facts, even if again the religious prism is applied to map that to "how God did it". The Catholic church still does a lot scientific research, recognising "How" and "Why/Who" are different questions. (Thats not dimiss the major, major issues with the modern Catholic Church, but their treatment of science isn't one of them).

​

At the risk of invoking the no true scotsman theory, a lot of the stuff that American preachers today are saying, were rejected a long, long time ago by theologans.

You might like this book by Coxeter, who also co-wrote Geometry Revisited. Tristan Needham covers a bit of non-Euclidean geometry in Visual Complex Analysis. Really though I believe non-Euclidean geometry isn't a discipline of its own; it's part of differential geometry, so you might be better served looking for differential geometry references.

I think you are after something along the lines of Porter, Easterling, and Sherif. This book bridges thermodynamics and "pure" solidification theory pretty well.

As another option, a relatively easy-to-read book is Farlow's book on PDEs for Scientists and Engineers. It breaks up a bunch of PDE topics (everything from the Heat Equation to perturbation methods) into short lessons using a relatively informal, non-rigorous approach. I'd highly recommend it for beginners and for those who'd like a quick overview of the applications of PDEs to areas in Physics/Engineering.

It's not a purely mechanical orientated book but I have found the Gieck Engineering Formulas book to be quite useful and it doesn't go off the rails with any differential calculus.
(http://www.amazon.co.uk/dp/0071457747)

It also is an actual handbook you can carry with you; if anyone on here has seen the Perry's Chemical Engineering Handbook in the flesh you will understand.

It's the best I can do.

> what's supposed to be nice about a math book is that the author distills the content down to the bare essentials with nothing necessary omitted and nothing unnecessary included (this makes time spent reading the book and doing problems from it fulfilling and efficient)

I disagree. That's what's nice about math. What's nice about a math book is that it teaches you math. If you're taking lectures and seminars at a university and discussing the subject with other students then a minimal, rigorous and terse textbook maybe just what you need. However, if you're learning math as a hobby in your spare time and on your own, a book that gives copious examples, and motivates the subject from many angles, is much more useful.

Visual complex analysis is a shining example of this kind of writing http://www.amazon.com/gp/product/0198534469/103-9283683-9227825?v=glance&n=283155

I just got this book a few weeks ago, it is full of awesome mechanisms.

Neither of those is the complex plane. The first is 3-dimensional in the real manifold sense and the latter is 4-dimensional.

It seems that you are confused about what the complex plane is, so I would suggest that you read Needham's Visual Complex Analysis. It's a very gentle introduction to complex analysis that also conveys very good visual intuition for what is going on.

A really fascinating book about the history of geology (with a focus on how much of it was shaped in relation to a cultural belief in the Noachian Flood) is The Rocks Don't Lie

Can't recommend it enough. It really puts modern flood geology in perspective.

I have the Mechanisms and Mechanical Devices Sourcebook, Amazon. I have the fourth edition, but the link is the fifth. It's a good book showing how to design them and has a ton of examples.

Just get yourself a copy of this and celebrate with beer.

My professor wrote this this book. It is excellent if you already have a memory of PDE's. It is also inexpensive.

Check out Partial Differential Equations for Scientists and Engineers by Stanley Farlow. I've recommended it to another engineer in the past and he seemed to find it useful.

I haven't read it yet, but Six Degrees: Our Future on a Hotter Planet by Mark Lynas is on my wish list.

Quantum Computing Since Democritus by Scott Aaronson.

A Friendly Introduction to Number Theory by Silverman.

Visual Complex Analysis by Needham.

Marks Standard Handbook for Mechanical Engineers

So good. Fascinating. Put it this way: if you don't end-up loving (loving!) this book, then Mech certainly isn't for you. So worst case scenario, this is a cheap way to find that out.

I use this one a lot for inspiration when I need to design new mechanisms.

https://www.amazon.com/Mechanisms-Mechanical-Devices-Sourcebook-5th/dp/0071704426

I used this book for my PDE class. It's meant to be supplemented with notes, but it does a decent job explaining material on it's own. That and it's super cheap for a math book.

Note that it has several errors in the answer key.

Mark's Standard Handbook for Mechanical Engineers.
At least it is a good reference whenever you want to remember how to do something, and learn some things you didn't learn in school.

https://www.amazon.com/Marks-Standard-Handbook-Mechanical-Engineers/dp/0071428674

You can look for an old copy of Mark's Handbook. This is a handy guide to pretty much everything to do with mechanical engineering.

Buy her this:
http://www.eetusa.com/civil-pe-catalog

And this:
https://www.amazon.com/Civil-Engineering-Reference-Manual-Exam/dp/1591265088

This is pretty much all you need to pass.

Read a book like that a few years ago. Six Degrees. It's about global warming and its likely effects.

Hey, how did you end up liking the book? I'm thinking of getting it myself. Also did the book have practice problems, or did you find them elsewhere?

edit: What do you think of this book as well? It was suggested to me by a professor: http://www.amazon.com/Civil-Review-Manual-Michael-Lindeburg/dp/1591264391?ie=UTF8&*Version*=1&*entries*=0

When you've gotten through those, and have a handle on the material, I'd recommend Bob McCarthy's Sound System Design and Optimization, Davis' Sound System Engineering, and Ballou's Handbook for Sound Engineers.

Try ingenious mechanisms
https://www.amazon.com/Ingenious-Mechanisms-Designers-Inventors-Set/dp/0831110848

Also look use NASA Technical Reports Server to look up papers that are available.

There's many good books/papers out there on these kinds of things.

The FE review manual (https://www.amazon.com/Civil-Review-Manual-Michael-Lindeburg/dp/1591264391/ref=sr_1_1?s=books&ie=UTF8&qid=1483628512&sr=1-1&keywords=fe+civil+review+manual) has a decent basic review of RC design. Plus this is helpful if you plan on taking the FE at some point. I think reading through the RC sections will give you enough prep to better understand the more technical literature in the textbooks you have.

Check out Visual Complex Analysis by T. Needham . This covers complex analysis in a very original and vivid way!

Visual Complex Analysis looks interesting, haven't read it yet.

Get yourself a student edition of some Autodesk products - AutoCad and Inventor at the least - to practice CAD and drafting skills.

For your particular case I highly recommend the textbook Visual Complex Analysis. Helped bring the "math talk" down to earth for me at least.

I recommend you to take a look at Visual Complex Analysis in particular the chapter on differentiation. In the first sections he explains the rationale for this restriction.

I like this book.

I like Partial Differential Equations for Scientists and Engineers.

>tl;dr recommend me a book

https://www.amazon.com/Six-Degrees-Future-Hotter-Planet/dp/1426203853/ref=asap_bc?ie=UTF8

There's "A Mathematical Coloring Book": http://www.lulu.com/content/4858716 (free download!)

Somewhat more serious, I like "Visual Complex Analysis": http://www.amazon.com/Visual-Complex-Analysis-Tristan-Needham/dp/0198534469/

If you have a chance, checkout the book Six Degrees: Our Future on a Hotter Planet takes an interesting look not only at what happens at four degrees, but also temperatures lower and higher. Essentially the book starts low and grows to the scenario of what would happen when we've reached six degrees by looking at evidence published in respectable journals such as Science and Nature

Mark's Standard Handbook is basically every MechE textbook crammed into 1. It is pretty expensive, but a PDF can be found with some googling.

http://www.amazon.com/gp/aw/d/0071428674/ref=mp_s_a_1_1?qid=1418950920&sr=8-1&dpPl=1&dpID=51X0PIIJgKL&ref=plSrch&pi=AC_SY200_QL40

For complex analysis, Visual Complex Analysis by Needham is often recommended along these lines. I haven't read it though, so I can't vouch for it.

It's Marks' handbook!

Search the right places and you can find non-official digital copies, if you know what I mean...

If you want to buy it, it's edited every ten years, and luckly, next year they will launch the 12th edition.

I've used this one by Farlow in the past. It's got solutions to most of the common PDE's you'll find in other books, but it's a lot cheaper. It's also less formal than a lot of other books, which may be good or bad depending on your taste.

If you're looking for something that covers a bit more than just PDE's, O'Niel's book isn't too bad.

So one of the huge things I did was before I even started practice problems I watched Marshall University lectures on most of the subjects. The lectures were from a FE review class and the teacher would step through practice problems and where the exact equations were. The most helpful ones were probably the math and probability ones where he would explain how you could pump out most of them using calculator functions in 30 seconds. Here's a link to the series: https://www.youtube.com/playlist?list=PLCV9OyAY5K-VOJjVCbvlDpvni2n3dG7jl

After watching all of these I then did the diagnostic exams for all sections from this book and did more practice problems if I felt I needed it.https://www.amazon.com/Civil-Review-Manual-Michael-Lindeburg/dp/1591264391

Something that also helped was I used a ABC format of studying. So section A was subjects I was confident I could answer a large majority correct. B were subjects I would probably nail like 60% of the time, and C's were kinda crap shoots.

That book is quite dry and abstract.

If you want more "why" and applications, try a book aimed at physicists or engineers.

Maybe this one for example

Look at Sound Systems Design & Optimization If you're looking for theory behind how sound systems work.

Graduate or undergraduate level?


If graduate, this is THE book to get.

This is much more applied.
