Reddit mentions of The Language of Physics: A Foundation for University Study

The Feynman Lectures are a perfect introduction to physics from high school level all the way up to degree level.

A good understanding of maths is essential to more advanced physics and there is an excellent textbook written by two extremely qualified headmaster's called The Language Of Physics: A Foundation for University Study which is what's recommended to first year University students and poses questions at the end of each chapter.

If you're looking for something a little less intimidating, then the A Very Short Introduction series have a perfect range of short (and cheap!) books on Physics: [Quantum Theory]
(https://www.amazon.co.uk/gp/product/0192802526/ref=pd_sim_14_4?ie=UTF8&psc=1&refRID=9A3MSV2XSQRYF880MYP6), Relativity, Particle Physics, Cosmology, Nuclear Physics, Black Holes, Thermodynamics, Astrophysics, Light and Magnetism. These are great little books that don't blow your head off!

Physics is an extremely interesting subject to read around and I wish you the best with it :)

Here are some Math-related books on my shelves:

• OUP - The Language of Physics (Loan; do NOT buy a copy of this. But do have one read through this. Only high-school maths necessary, and gives you a nice overview.)
  
• Kreyszig - Advanced Engineering Mathematics (I highly recommend this book. Read the first few chapters of each section for now (e.g: Ch 1, 2, 6, 7, 8, 11, 13, 15, 19, 24) since those are likely to be what you'll be covering first.)
  
• Stephenson - Mathematical Methods of Science Students (Others recommend this. I have a copy, but it's not something to pick up and read through. Quite dense and compact, more of a reference book that happens to include exercise problems with answers.)
  
• Kasdin & Paley - Engineering Dynamics (Not a maths book, but hey, if you've done Physics in HS, you pretty much get the grounding to do this stuff, especially after brushing up on ODEs. Take a look through Appendices A-C first, and use Kreyszig if you don't understand the maths.)
  
  I haven't read every introductory book in existence (neither have I had to), so these aren't necessarily the best ones.

Hi, what I am doing is plotting the probability of an electron in ay given position and seeing how changing its energy, spin projection and magnetic orientation.

The other side of my project, which I did not discuss there, was investigating quantum harmonic oscillators.

The books that I learned this from were A Cavendish Quantum Mechanics Primer and the language of physics; I think the former is better than the latter.

Also, try to read through the comments on that thread and come back with any questions. I am currently doing a writeup for the whole thing, so once I have that finished I'll see if I can share it.
