Notes from a mathematical physics degree

I took many notes throughout my undergraduate degree in mathematical physics at the University of Waterloo. Once I finished my last exam, I decided to digitize all of my notes and discarding the physical copies. Below, you can find all my notes from all of my classes at the time.

Anti-curl and Poincare's lemma

A brief look at potential functions in 3 dimensions, and how Poincare's lemma can make it easier to solve for vector potentials.

Physical symmetries result from what we think good scientific theories are

Why do physicists talk about symmetries and conservation laws all the time? It's because that's what a good scientific theory looks like.
