My remaining ties to the physics department resulted in me running two different workshop series for the undergraduate physics society back in 2023/2024. The first was entirely focused on building up the fundamentals of linear algebra and applying them to quantum mechanics. For the second we decided to go with a series of lectures on a variety of topics including fourier series, quantum entanglement, real manifolds, 4-vectors, and computational methods. The compiled notes for both series are linked above.
Of course, I did not put these together alone. Credit goes to the entire Physsoc team of the time along with Morgan Arnold and Rio Weil.
