There have been a number of issues raised in the learning of quantum mechanics that i am unsure of.
1. How can you explain electron spin in terms of waves?
2.How and when do photons interact with 'virtual' electrons in a vacuum?
3.How do photons interact when they are travelling away from each other i.e. at 2c
4.There is a way of describing electrons interacting with each other that means they travel back in time (this is deep QED) can anybody explain it to me?
5. I understand the purpose in QFD, but can somebody explain why is involves bosons, and more deep explaination?
