Terrible lectures and section don't bother attending he really does not know how to teach. Ridiculously hard midterm and final. My advice switch professors or take it a different quarter just avoid him.

I came back to write a review after taking 120B again this quarter with a different professor and honestly this material is easy Oh made it unnecessarily hard. He is bottom line a horrible professor: lectures are confusing, homework is graded way too toughly, midterms were extremely difficult for no reason. You'll regret it if you take 120B with Oh

I had Oh for PSTAT131. He's a wonderful professor who explains details clearly. One thing that you should be pay attention to is his pop quiz, which is harder than I imagine.

Very poor professor, really failed to make concepts clear or explain the subject well. Homework was graded way too toughly instead of checking for completeness and effort. The midterm average was far below failing and yet there was no curve. Final was unfair as well. Bottom line don't take this professor. Got an A in 120 just to fail this class.

VERY HARD professor. I got an A in 120A and I had no idea what he was talking about half the time. His midterm had a class average of far below failing, unreasonably hard tests, difficult to follow during lecture. Very nice guy though, he is definitely just new and trying

I had Oh for PSTAT 120B and I thought he was unfairly tough in that class. However, he has made a dramatic improvement in 131. The material is pretty dense, but he does his best in lecture to break it down. There is no midterm or final, the final project takes up 50% of your grade and it's pretty straightforward. Homeworks are partner assignments.

Great professor. The best one in UCSB phys department

Professor Blaes might just be my favorite professor I've had at UCSB. He's incredibly knowledgable and an excellent lecture who's able to break down very complex topics in an organized and (relatively) easy to follow way. He made use of many demonstrations as well, which kept class interesting and engaging. In office hours he's approachable and helpful and more than willing to walk through any topics, and I highly recommend going to his office hours. All in all, if you have the opportunity to take a class with Omer Blaes you absolutely should. You can tell he's in love with what he does and his enthusiasm is infectious.

DO NOT take courses of this professor Exam was verrrrrry hard and grade was given toughly even if you work really hard

Overall a really good instructor,; does his best to try to make sure his students understand the material. Class is only 1 midterm, 1 final, and HW -- HW is pretty fair and only a few problems each week.

His lectures are often boring but he does go through a lot of examples. The homeworks are really hard but are also much more difficult than the exams. He's a young guy so will probably (hopefully) get better.

The lectures were unclear at times, however, Oh is extremely helpful in clarifying topics in office hours. Oh gets a bad rap from students who most likely didn't put in the time to read and go to office hours. Read the book, ask questions, go to s office hours, and you'll do fine. Don't expect a good grade if you aren't willing to work for it...

The class is extremely tough. He moves very quickly in the lectures and it's hard to keep up, and a lot of it relies on you already knowing most of the definitions and theorems in 120A. He's a nice guy though, but the lecture and the material is dry and difficult.

This is a pointlessly difficult class. The professor is a nice guy, but is new to teaching. He doesn't know how to explain examples while he is doing them, and assumes the students are already familiar with the terminology. The midterm average was around a 34%. There is no way to pass this class with out reading very thoroughly and analytically.

He looks nice and he is a nice person. This is his first time teaching and the midterm average is like 30 % something, it scars most of the people. the lecture is useless you pretty much study on your own , there is like no point to go to his class. think twice before you take it.

Terrible lecturer. Tests are impossibly hard. The class average on the midterm was a 30% and the highest grade was a C. Lectures are irrevlant to subject matter and the material is really difficult. He is a really approachable and friendly guy so it's shame that he is so poor at teaching. I don't not recommend taking him.

Useless lecture. not making any sense. You have to study on your own and test is totally irrelevant with homework or lecture.

Prof. Blaes is the best professor you will have at UCSB. I took 4 classes with him and he is an amazing professor and person. Go to his office hours he is very helpful and incredibly knowledgeable. He has a really good grading scheme which always helps the students.

I once heard a quote that a bad teacher tells, a good teacher explains, a superior teacher demonstrates and that a great teacher inspires. And in that regard, I think he's a great teacher.

Great Professor. Interesting lectures and very clear and helpful. Very fair grading scale. Is clear about what we are expected to know, fair tests.

Best professor I've ever had. He made me love Physics again. Take California Physics with him. He posts all the lecture notes online. After the midterm, we only had a final paper and homework--in any other physics class attendance would drop to zero at that point. In this class, everyone went out of respect for the most interesting prof at UCSB

Best teacher I've ever had. He'll work you hard though.

HE IS SO HARD. But also, incredibly compelling and inspiring. Going to class was something that I was excited to do. Weekly homework. Truth be told, the exams were brutal. Not to mention the textbook was only fractionally useful. You love Physics? Take Blaes, but kiss your sleeping hours goodbye..if you'd like to pass the course with a D or better.

Blaes is amazing. He is a wonderful teacher-- very enthusiastic, very approachable, very clear. I'd take any class he taught just because of him.
