Hello, I am currently a high school senior. I've been admitted for university to study electrical engineering and possibly nuclear engineering. I also enjoy learning about topics including quantum mechanics and special relativity. I would major in physics except it's not a career I want to...

As I am currently a high school senior with basic experience in physics and calculus, and much of this terminology flies over my head, would you know any good places where I can break this down so I can understand it?

This is Immortalis. I am an engineering student who joined so that I can learn more about physics. I am particularly interested in GR and QED.

I am trying to learn about Feynman diagrams and am confused by some of the notation. In particular, what do matrices, in particular the Dirac adjoint, have to do with Feynman propogators and why are they in imaginary terms?
