Reddit mentions of Uncle Albert and Quantum Quest

I don't know. I studied Quantum mechanics at university (albeit briefly - I switched to another course two years in), and my opinion of qCraft has always been quite negative. It's a weird mod, and QM is definitely weird, and there are some roughly similar concepts (many QM "oddities" are based on measurement, and qCraft largely deals with observational changes)... but it just feels like it doesn't represent QM from a scientific point of view, but rather from a layman's point of view. It's the sort of education, which, while I guess technically not wrong, might also instil a lot of bad conceptions of QM.

I can't really pin down what good teaching of QM would look like, although if anyone is interested in trying to explain it to children, I'd highly recommend taking a look at Uncle Albert's Quantum Quest. I guess the two things that I'd really want to see in a Minecraft mod that tried to properly teach QM would be a) something akin to the double slit experiment (which - in it's many variations - explains a lot of what QM comes down to), and b) probability waves and distributions. Sure, there are mathematical and rigorous ways of teaching these that probably aren't appropriate for children, but most kids can comprehend the concept of things being more likely to end up in one place than another.

tl;dr - I'm not a fan of qCraft, because I don't think it teaches QM, but rather it tells everyone that QM is weird, which is not in of itself worthy of teaching.
