Professor Geller is a very interesting and funny lecturer. His class is fascinating and a fun GE to take. He is passionate about the subject. There is quite a bit of textbook readings and weekly homework assignments, but overall, an enjoyable class.

great lecturer, loves to talk about astronomy. Very friendly guy, but gives a lot of textbook readings and assignments on a weekly basis. All in all, not that challenging of a class. Enjoyable GE.

This class can be a lot of work for non stem majors but is very fascinating. He is super funny and very passionate about all things astronomy so his lectures are always interesting. Exams are multiple choice and very straightforward. He is happy to go down any rabbit hole about physics.

Honestly I'm not sure why Geller gets so much hate. I find him to be quite entertaining and his commentary in his lecture videos makes me laugh. He is a good professor and I feel like I've learned the most physics than the other two classes in the series. I strongly dislike physics but I will say that Geller definitely does keep me engaged.

Geller is a good professor. Not gonna change your life but he is super into astro and the class is generally fun and basic. He will not teach you the math, however there is very little math and you are probably fine if you know basic algebra and memorize what each variable means (T for time etc.) Just be ready to read and do constant achieve work

Geller teaches in a conceptual way. The pro about this teaching style is you're likely to understand how the world works better. The con is that learning problem-solving that matters for MT's is done on your own time. He gives you all the tools though. Know how to do the BP's (which aren't a lot) by heart and look at "good-student" notes. (6.75/10)

A funny dude but his lectures are very heavy, not to mention the huge study load which included homework and 8 sections of reading a week. His sections are where you are graded (weekly quizzes), which can mess you up because his grading is weird. Just not my cup of tea.

Amazing lectures, is always communicating with students about questions before, after and with emails. Essays in sections are usually straightforward, and multiple-choice exams. Geller also loves answering questions about random topics.

Lectures are packed with info but if you find astronomy, math, geology, etc interesting then it will be a fun but semi-hard class. Lots of reading, minimal math, mostly memorization.

professor seems chill, but too too much homework. As a summer online course, it takes about at least 3 hours per day.

Lots of homework which make up a lot of your grade which is super nice. Exams are hard but fair, if you keep up with the homework and do the practice problems he gives you will be fine. His lectures are super entertaining and interesting, always doing some fun demos.

geller is very passionate about astronomy but you have to stay on top of the lectures and assigned reading or the concepts will be hard to understand. homework was online but easy, sections were essay questions (also easy), but some midterm/final questions were tricky and weren't covered in lecture.

Geller is a good lecturer but PHYSICS IS HARD. Test averages are pretty low, but Geller always sets reasonable curves to ensure the success of his students. The online homework is tedious, but a big grade booster and good for practice. Downside to taking Geller is you don't know what to expect on exams since he only has 5 practice questions total.

He's a chill guy. He loves Astro which makes it fun to hear him talk about things like the multiverse. Hw is through Achieve which is not my favorite but its manageable although kinda annoying. For a GE though, it does take a lot of time for reading and then rereading to study.

Class average for the Midterm and Final were 57%. Multiple students emailed him and his only reply was "you should try harder". The same class with Freund had an 85% average.

fun lectures that are both interesting and informative. cool demos. focuses more on the concepts rather than how to solve a problem in lectures, but it works b/c the textbook. tests are reasonably difficult. only dropped due to a medical emergency and not Geller himself

On your next pass time look at Geller vs. Freund on gold. Freund's class will likely already be full. Geller's will have 300 open seats. That says enough, doesn't it.

Prof Geller was very thorough with his lectures, you should go to lecture if you want to understand the material fully, along with reading all the chapters assigned. If you're interested in this topic, its not hard to pay attention and grasp the concepts, if you're not interested, its probably going to be rlly hard. Lots of hw too, but easy.

Bro loves Achieve, and while it's irritating, I learned more from Achieve than I did from him. You gotta teach yourself. He's passionate, but lectures are highly conceptual and fairly disorganized, with very few examples. Tests are all MCQ and mostly fair; you just have to practice. CLAS helped a lot, and so did the practice problems and exams

I was placed into his class because the other sections were full and was a little nervous due to the other rate my professor ratings. However! Geller is my favorite teacher at UCSB so far, even as someone who isn't fond of physics. You will succeed if you understand problems from HW, textbook, and assigned practice problems (not rote memory).

Not very good at teaching, but I was fine because I took physics in high school. The content is essentially the same as AP Physics 1. There's also a few homework assignments due every week and they're graded by accuracy. Start learning the content before the quarter starts and be prepared to teach yourself almost everything.

Conflicting feelings. Lectures are pretty useless, purely conceptual. Homework is a large percent of your grade, so failing is pretty impossible, but that's offset by the low test averages (71, 60, 57). These were his highest averages ever, according to him. You have homework due every day. Take Freud if you can't take a mild hit to your GPA.

I adored Geller's Astro 1 class. You can tell he loves teaching it. The class was thought-provoking and made me appreciate life more. If understanding the universe, stars, planets, and other celestial phenomena sounds boring to you don't take the class. His physics courses artificially lower his rating. Don't let that deter you from taking Astro 1!

He's is SO DISORGANIZED and BAD. He openly stated on the first day that his class wasn't meant to be a weeder course, but it definitely felt like one. He also mentioned that the department was unhappy with the discrepancy between his class and Freund's. His teaching made class impossible. He gives 3 question practice exams with no explanations. .
