Always helpful, tries to make you understand.

Sebastian's lectures are hardcore and derivation-heavy, which I like a lot. He is very happy to answer questions and clarify things. The tests are not hard, and he would brief you before midterms and finals, which are not cumulative.

One of the best! Very thoughtful, open to questions, wants you to understand and appreciate the material, extremely accommodating. His lectures can be hard to follow at times, make sure to ask questions about the proofs if you're lost. He's happy to clarify in office hours too. He'll tell you exactly what topics will be on exams.

I took 23, 24, and 104 with Prof. Streichan and he was a gem in all three. One of the few physics professors who you can tell truly cares about teaching and his students. His homework is manageable and exams are easy (in the context of the department, of course). Lectures can be derivation heavy, but he never fails to make the material digestible.

Good lectures, but does not cover all contents needed for homework so a bit confusing and need self study

Professor Streichan is great. Homeworks are from Taylor, he is very fond of derivations, so expect one on the midterm and another on the final. They are pulled straight from his lecture notes. He posts his notes on guachospace, but his writing can be difficult to read at times. So its best to go to lecture. He is also very accessible in his office.

To my knowledge, this quarter (Fall 2018) was prof. Streichans first time teaching 103, so we were the guinea pigs. The midterm average was 50%. The curve helps a lot so its kinda hard to fail. He is a super nice guy who actually cares about students. Grade breakdown: Midterm 25%, HW 30%, Final 40%, Participation 5% (Section) + 5% extra credit.

Best ever
