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.

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

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.
