Professor Samani is by far the best professor I've ever had. The content is quite difficult, but he makes it approachable and interesting. I look forward to this class every day. The homework is tailored well to the tests, and office hours are informative and fun. He has two regular office hours weekly that are always really interesting, and one open office hour per week, which is not strictly physics-focused, but always has very thought-provoking conversations.
Overall, you should absolutely take this class with Professor Samani if you can.
