I took this guy for both 20B and 110A. I mean overall he is actually a nice guy and you can tell he cares about his students' sturies. However, he failed to explain concept during the class which sometimes leads the whole class in confusion. But his notes are incredible helpful so make sure you understand them. Also, remember those derivations since he likes to test on them. I managed to get A in both his class. If you study hard, you can also do that

His person: very unapproachable, he's too damn smart

Lecture: ZERO interaction with students, failed to explain things clearly most of the time

Midterm:
MT1)Avg: 63%
MT2)Avg: 49%
Final)Avg: 63%
My grade: A

MT1 covered the least amount of material so make sure you get good grade for it.

Proofs required!

He loves to put things up that are totally out of the blue, you can't do anything about it :(

Study tip:
1) Read course reader written by him, make sure you understand everything (quite readable)

2) Don't read textbook, only read section 2.9 and 3.4. Everything else in later chapters are pretty much useless & overly complicated

3) Again, concentrate on course reader & lecture notes NOT the text

4)Do extra problems that aren't assigned (esp. chpt 6,7,9,12)

5) Memorize proofs (the important ones). e.g. maxwell relation, derive equation for K & G for ideal gas, phase rule etc

There's a reader for this class. GET IT if you're taking this class with him. It's pretty helpful. The material for this class is very challenging. I think that's why a lot of people complain about him not being clear about thing during lecture. To do well in this class, you need to do more than attend lectures and doing the homework. Office hour is almost a must to do well. I learned a lot of interesting thing in this class and I really enjoyed it although I ended up with a B+ in the class. For the midterm, he gives you almost all the time there is in the world... well 3+ hrs. His final was a big challenging. But he's pretty fair at curving the class and such. Overall, this course was great, and I think Dr.Neuhauser does his best at teaching the subject. I would recommend taking the course with him.
