Geller's a downright awful lecturer, but at least he shows enthusiasm for it. He focuses too much on applications and not enough on the theoretical aspects of physics. That being said, do the book problems and use lecture as a test to make sure you're on track, not very useful otherwise. Could've had potential, but interesting topics nonetheless

Prof Geller is a great teacher. He lectures on exactly whats going to be on the test. His tests are basically the Sapling assignments so be sure to go through them before each test. I got an A just by going to lecture and review notes and Sapling the day before the test.

Geller is eager to answer questions during lecture, and although there is assigned reading, the lectures cover most of the material so the textbook is only necessary for some terms or concept that you don't understand, and the homework. The class was pretty interesting

Just as Professor Geller said from day one, this class had a good ratio of easy and interesting. Super cool class, great professor! Highly recommend.

Robert Geller is a solid teacher. His lectures are not too boring and he encourages questions. If you pay attention and take notes you can do well. I felt like I really learned the material in the class.

Geller's like your cool traditional Isla Vista teacher from the 90's. He teaches you the basic 6C concepts using compelling demos that will stimulate the Gaucho mind (e.g. the hallucinogenic appearance of soap) albeit still using overhead projectors. He's funny, his teaching emanates passion in his teaching, but watch out, his tests can get you!

He is an interested and goo-natured professor. He is supportive of all students and he will reassure students that are struggling. I really appreciated that because I am not the best at physics. He had iClicker a few times and his tests were very similar to the Sapling assignments.

Professor Geller is awesome. The man is a genius and is a fantastic instructor. He is very reasonable when it comes to expectations of students, but he also loves to push them.

Just an average physics class. If you took physics in high school, you'll be okay with just doing the homework and practice problems. I didn't buy the textbook and I got by just fine. Geller has really interesting in-class demonstrations. He's a funny guy, but his teaching lacks clarity. He makes lots of mistakes in lecture too. (iClicker needed)

Professor Geller is great! He conducts his lectures at a steady pace, and he loves answering student questions. Attending lectures was necessary for comprehension, and CLAS helped a lot too, but overall class was fair. No surprises on tests.

Professor a fraud and un trustworthy beware

Geller has my respect above most professors. He is very understanding. He cares about his students truly wants them to do well. However, that does not mean his class is easy it is sometimes not that interesting either I am not a fan of physics, nor am I very good at it.. But he made it so worth it and this was by far my favorite physics class.

Though the material is not that hard, Prof. Geller makes the class annoyingly more difficult. He grades homework based on accuracy, which is somewhat annoying. The lectures are pretty helpful, and he doesn't assign insane amounts of homework, but the fact that he grades homework and uses iClicker means attendance is pretty much mandatory.

I thoroughly enjoyed Geller as a professor. I think he was one of my favorite professors at UCSB. There were some very challenging concepts, but Geller had a way of making them seem simple enough for me to understand for the test. He was very generous to us this quarter regarding the events that occurred. Also, homework and iClicker help a lot.

Professor Geller is great! He's a very kind person and makes lectures interesting by focusing on more interesting topics and frequently using demonstrations. Super fortunate to have him for Physics.

Super helpful and understanding professor. He makes the lectures interesting. Homework and exams are fair. You can tell he cares about his students a lot.

Awesome professor and you only spend about 2 hours a week on the class.

Geller is one of the best professors I've had at ucsb. I hate physics but he makes it as clear as possible and his exams are fair.

DONT LET THE NAME FOOL YOU. Its a really hard class and the Geller is just a horrible teacher. He speeds throughout the lecture and expects us to already understand the concepts without him really explaining them. He shows no interest in having his students succeed and his midterm was ridiculous. DO NOT TAKE THIS CLASS! NOT FUN!!!

Professor Geller is a great professor. He is so willing to answer questions that he would often stop lecture just so we could ask questions. For the midterm and final, really understand the CONCEPTS he teaches in class, and keep an ongoing list of equations, you get to use a cheat sheet for both tests. By far my favorite professor

Cool professor that really tries to do his best to engage his students in the material. If you pay attention and do the homework you'll do fine

Geller is a good professor but you will have to study for his tests. He provides plenty of demos to reinforce the general concepts of physics and as long as you can understand these principles, you should do well. The tests are difficult, but are manageable if you study both the book examples and the homework assignments, you should be fine.

There is no way to prepare for his midterm and final. The only reason why you need to go to lecture is for the iClicker because the rest of it is full of pointless demos. Do the mastering physics and understand it, and hopefully make some good guesses on the test and you will be okay. Just don't expect an A.

Geller is a nice person not a good teacher.I felt like I exhausted all my options with this class & still did not pass.I attended clas,did the homework & studied for the exams.The midterm and the final were very difficult,no way he prepares us for the exams.He does some cool demos but I mean I don't think I could've done anything else to do better.
