I remember taking the upper level thermo courses for my undergraduate. Through the semester, they introduced a handful of equations for specific scenarios. Then the final was like 4 questions in 3 hours and with the equation for Gibbs Free Energy.
Lowkey, just differential equations made me want to kms. Shrodingers equation was bad but not so difficult as to be singularly memorable. My memory of my physics courses are a void and I switched my major.
Honestly the math just took my passion out of physics. I love how physics explains the world and I love how strange everything is. I love learning about physics but doing it... I used to think I was good at math lol
Difeq is a horrible pain in the ass until it clicks and becomes easier than that stupid non vector geometric integration. Is it really too much to ask to be allowed to stick to matrices and vectors‽
