Hi, I am a guy from Norway who loves physics, specifically Quantum Physics, and I hope that one day I'll be physics teacher. I've spent some time here before, but didn't make an account before now. I hope I can help others who pursue science and hope others can help me as well.

Hello, I am a Junior Math and Physics undergraduate and I just wanted to get involved in this community. Thanks, -E

Hi all, I have an undergraduate degree in Physics, but I've since specialized in more environmental applications of Physics. I've taken a few quantum Physics courses as part of my degree, but, if I'm being honest, what I took from those courses was more of a mathematical view of the field, such...

I came here after noticing a thread I found amusing where someone named "vanesch" said in this post that theories like SED are unneccessary ontological "toy worlds" for people who need to have an explanation behind the formalism of QM, to make themselves feel better. Mainly I just wanted to...

Can anyone recommend a good Introduction to Numbertheory with excercises and of course proofs Thanks for any recomendations.
