I consider myself pretty well-read on science topics — I took a couple of quantum mechanics classes in college. But then I come across articles like this which completely humble me, reminding me just how much depth of knowledge there is in our world.
I looked it up after reading that rotating a particle by 360 degrees doesn’t get back to where it started, but instead you need 720 degrees of rotation. Some of the math in this article looks familiar to me but most of it is incomprehensible to me today.
And this is from a free, volunteer-written encyclopedia that I can access from a phone. That by itself is amazing.
