Lectures are mandatory because iClicker, but lectures are very pointless. If he is not ranting about something he is doing a demo. Little to no notes are taken during lecture. Exams are free game and formula sheet given is not helpful whatsoever. It is best to find your own resources and learn from the homework and CLAS

Geller does not teach his students at all. All he does is demos in class, and maybe covers 1 or 2 equations. He should stick to research and let someone who has a passion for teaching do the teaching. There's no clear level of expectations that he has. Be prepared to teach yourself everything, because he won't be the one to teach you.

Geller's lectures were really fun to attend because of the fact that he does a lot of demos and talks about real life applications of the physics. We do a lot of problem solving on Sapling so it's helpful to see why. He uses iClickers but that helps boost your grade. A lot of people don't like his lectures but they're also the ones who don't go.

Lecture is focused on concepts and demonstrations instead of problem solving which isnt for everyone. I personally think its better that way bc the math isnt hard but if you dont understand the concepts you wont know where to start. Read the textbook and do Vinces CLAS problems and its not too hard of a class.

Geller's lectures are pretty interesting but they wont help you pass the tests. Reading the book is a necessity in order to pass. CLAS is also super helpful, as Geller does not do practice problems in class and the tutors help fill in a lot of information he skips over. No curve but his test averages were quite high (78 on mideterm and 72 on final)

To be honest, Geller's lecture is boring, he doesn't talk a lot about problem-solving strategies but a lot of experiments and other stuff. So then you have to really read the textbook and do all the questions from CLAS. he doesn't even have practice exams which would make you feel very nervous before exams. His exams are way easier than homework.

Average was super high. Was hoping to get a B because the class has a historically nice curve but ended up with C+ because there was no curve in the course.

Geller's lectures are absolutely terrible, but you kinda feel the need to go anyway. Out of an entire quarter (TR lectures), he had three day's worth of iClicker. Doesn't teach, just talks about applications and astronomy. Also, he sounds like Bentley from the Sly games. Big oof.

Geller is an average professor. He is really passionate about physics which is great, but his lectures are very conceptual, and he doesn't cover much of the 'practical' stuff. The final only covered the concepts that he discussed in class, so just do problems to familiarize yourself with the equations and you'll be fine.

Lecture is mostly conceptual stuff that wont be test material, but still go for the equations and problems that he wants you to know. Practice hard problems and go to CLAS. Read the book. No curve or very little curve.

The test is much different from his class material.

Geller is a true gem. He really cares about his students and his passion shines through. Straightforward exams if you like physics.

Final harder than the midterm. Lectures are mostly applications, but the few problems he does are helpful for the exams. CLAS is useful. Practice doing hard problems to be ready.

He goes over more conceptual and application stuff in class, so some people didn't like that he doesn't really go over solving equations in class. The midterms and finals are based on the homework, so definitely study homework problem and you'll be fine. Also recommend going to CLAS.

You will have to do a lot of studying on your own just to pass the class. I Recommend taking any other professor. Never once did a practice problem in class with number figures(like they are on the tests).

I wanna attend any of his classes again. Each lecture he introduced only include a small part of chapter in the book. Sometimes when he had a cold he just skip the lecture and leave us to learn by ourselves. He always assign a lot of homework with tough and strange requirements. And what his lecture did little contribution and help for homework.

Geller is a great lecturer and person, but he also doesn't cover everything that you need to know in lecture. Reading the book, doing the homework, and going to CLAS will supplement his lectures in order to be prepared for tests. He only has two homework assignments a week. I really liked his class, but the set curve makes it difficult to get an A.

I dislike physics but Geller was such a good teacher. He doesn't try to trick you. I strongly recommend doing book problems because they really help you prepare for the midterm and final.

Took Geller for Phys6ABC because he's an amazing professor. Grading criteria is straightforward and almost everyone gets at least a B (75-89%) in the class. The tests will determine your grade in the class and there's only 2 or 3 so be well prepared. Vince Zacone's CLAS online material is your best friend. Geller is an awesome person, you willlearn

After taking Freund for 6C, I found Geller's class to be more challenging - I had to put more effort into studying and actually knowing the material, rather than memorizing equations. However, Geller's passion for physics and science in general made the class interesting, and I didn't mind going to lecture. Don't forget to bring your i-clicker!

Geller was alright but kinda boring sometimes. He really cares about his students.

Best physics teacher I've ever had. He doesn't do flipped classroom like other teachers which is helpful and takes tons of questions and does a ton of examples to make sure you understand. He is really funny. Tests are very fair compared to other teachers-doesn't trick you and tells you how many questions of what topic will be on there. One midterm

Most of the (many) issues I had with the course are due to the poor curriculum, which is set by the department and not the professor. However, Geller was often smug, condescending, and discouraged us from going to office hours for homework help. PHYS 1 is easy if you have taken AP Physics. If not, prepare for a long slog with little/no support.

Halfway through the quarter, and personally I dislike his teaching style. Lectures are pointless, only reason to go is because of iClicker points but otherwise you do not learn much through his lectures. The class is self-taught and he only provides demonstrations of the main concepts rather than actually going over what will be on tests.
