I loved this class! Not everyone did, but he was fair and made it really easy to get a good grade if you put the work in; weekly assignments that reinforce material were a huge portion of your grade, so just read the textbook and do your homework. lectures were boring but he was a cool guy and funny, either way the textbook covers the material.

Astro1was such a fun course to take if you want to know more about the universe in a very generic way. There were a couple of topics that we went super deep into, but nothing too bad. There is math involved, however it is very basic plug in equations. Reading the textbook is a must. Geller was a great lecturer and I enjoyed learning in his course.

I made a big mistake taking this class as a GE when I hate math, this class involves physics. He has his on own book which you must purchase online to access homework. TEST HEAVY your graded on the homework that is so easy to do because its online and everyone uses sources to do it, professor even pointed it out. Don't recommend taking this.

I can't understand why people would rate him badly. I think he is amazing, despite of what other people think. He is cool, does some amazing demos, and gives us quizzes on Achieve that let you earn an A on it. I do believe it is a easy A, as long as you show up to sections and the lectures, study hard and then it will pay off in the end. Love this!

Geller's lecture style manages to make concepts that are easy to understand in pre-lecture assignments much harder to grasp during lectures. From my experience, if you ask for help after class he's going to respond as if it's insane you aren't grasping the subject. You're essentially teaching yourself physics which is already hard enough as it is.

This man is a king. No exams or final this quarter just quizzes and homework. Although online, lectures are as interesting as they are helpful. Geller is not only an extremely capable lecturer, but is overall just a nice, cool guy who cares about his students' success. I could not recommend him more, the best professor I've had at UCSB.

Nobody enjoyed this class at all. Long and boring lectures that are extremely off-topic. Barely any material is actually covered, only broad and off-topic discussions. Lots of "rambling" in a sense. Class was mostly empty. The final was extremely difficult and the average was very low compared to him praising 6C and saying how easy it was vs 6A & B

I adore Geller! there are a lot of topics to cover but he tries to trim down as much material as he can. The final is a heavy portion of the grade and hard. But the midterms are usually easier as he gives practice midterms. Homework problems don't help/aren't on exams but saves your grade as its are worth as much as the final.

The physics is tough, but Geller shows true interest in his field is fair with the curve. I personally thought the tests were hard but the online Achieve homework is CLUTCH when it comes to grading. It is a good proportion of our total grade and makes up for the -in my opinion- hard tests. Only issue is that lectures are broad compared to Hw.

So this is a hybrid class because covid messed everything up. His lectures are terrible. Conceptual examples, no further examples or questions. You have to teach yourself. The homework is heavy but it helps with practice. Fingers crossed I pass this class, but the person teaching me this material is myself.

He gives extremely easy conceptual based questions in class during lectures, the hw is hard and there are at least 5 things due every week, then comes the tests covering only math problems that he never taught in class That we have to teach ourselves !! We frustrating class felt prepared for exams and it was never enough

At first I wasn't sure what to think of Prof. Geller - His lectures were super fast paced and at times a bit disorganized, but over the 10 weeks of the course, I developed a lot of respect for him, and came to actually really enjoy his lectures. It's definitely a tough class, I won't lie, but he is encouraging and supportive with his students

Geller is genuinely a horrible professor. Although you can tell he knows a lot about the topics and wants the students to be interested, his lectures are horrible. All he talks about is conceptual ideas when the exams were all math problems. Basically had to teach myself everything for the midterm and final. Do not take this class with him.

this is a horrible professor just because his final exam is so difficult. The average score of the final exam just 57%, but this is just an introductory Course of physic. I am studying economic, I choose this course just want to satisfy my ge requirement. so, I cannot understand why he make this introductory course final so difficult.

He's great, class was terrible.

I see a lot of people giving rave reviews and then 3/5 stars. He deserves a 5/5 rating on rmp based on those people's comments and my personal experience. He was on top of any issues that arose technologically as well as responding surprisingly quickly to my emails when I had questions on class concepts. I enjoyed this class because he taught it.

He is an easygoing prof with understandable lectures. Pretty easy class with no exams, and HW was 75% of your grade (sadly homework deducts you if you get an answer wrong which is annoying), quizzes 25%. I would much rather have him for 6B than Freund. Oh well, I don't get a choice.

Took his class for Physics 6A &C. Such a empathetic professor and very understanding of his students especially in this pandemic. He drops your lowest quiz/ hw & curves hw. I like how the quizzes arent worth majority of your grade. I used to dislike physics but Geller def made me like it a lot more.

He's a solid choice. He's not gonna inspire in you a firey, lifelong passion for physics, but you probably have to take 6ABC for your major, so he fills that role quite functionally. He doesn't make things harder than they have to be, which is prob what you're looking for.

Geller is an excellent professor. I took him for PHY 6A and 6C during the pandemic switch to online learning and he was very accommodating and made the class manageable in an online format. He's a funny guy and is very passionate about physics and astronomy. He makes the material understandable and grades mostly on homework and weekly quizzes

Prof. Geller is great! His lectures are pretty interesting, but he does speak really slowly in them so make sure to speed up the video. Since the class was all online, he didn't make us do a midterm or final, so our grade was dependent on Sapling homework and quizzes only, which really decreased my stress level.

Geller was very considerate with his grading policy, 75% sapling hw and 25% weekly quiz. You can leave the quiz open the whole week which allows you to answer the questions gradually. The hw isn't hard at all and enough time is given. He also dropped the lowest scores in each category. Overall an easy A if you put in minimal effort

Homie a real goat, very understanding and he explained things in a way I understood easily. Also is very understanding when it comes to bad life circumstances.

Took the class online. Your grade is 75% homework and 25% weekly quizzes. The quizzes were pretty easy as there was no time limit once you started the quiz and while the questions were specific they are all from the lectures. He's really fair and accomodating and you can tell he really cares about the class/his students. He even gave a 2% curve.
