The emphasis is on developing some intuition about the role of symmetries in physics, rather than going through rigorous mathematical proofs. Theorems will be proved at the level of rigor customary among physicists.

He doesn't believe in shoes. He is great at explaining things from the ground up so lectures are very insightful but it's easy to get lost. The homework is wild but the quizzes are easy and the exam is based on the quizzes. It's a lot of work but he's amazing.

Though sometimes the explanation are a bit abstract and hard to understand, but he's accessible outside of class, so I can still understand most of the contents. Also, the homework and test have reasonable difficulty, which the class is enjoyable.

Excellent professor! Occasionally went a bit slow in lecture, and the homework was much harder than the quizzes or exams.

Great professor, not much else too say. You should expect a lot of work is Physics 20 series regardless of the professor.

Does not give the most clear answers to your questions. Pretty chill dude and his lectures were pretty good imo
