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

while he may be a good physics lecturer he makes his tests extremely difficult. you can do all the homework and problems in the book but he throws a curve ball at you on the tests presenting you with problems that are 10 times more difficult than the ones in the book/hw.

Geller's lectures are very interesting and he is extremely good at clarifying difficult concepts. The course will be extremely easy if you are math oriented, but not impossible if you aren't. Weekly homework from the textbook, i-Clicker during lecture. 90% of test material is from lecture. I got an A without doing much textbook reading.

Geller's great! His lectures are clear, and he keeps astronomy pretty interesting/fun. The class isn't that difficult if you start the homework early and if you have some interest in science/space. Make sure you understand basic concepts before tests. I never went to section and still got an A-. Still wish he curved though!

Seemed like a nice guy and performed some interesting demos in class, but other than that his class was extremely boring. Class was also very hard. there were weekly hw assignments that took a long time to do. i assumed all this work would prepare me for the midterm and final but those were still extremely hard. DONT TAKE THIS CLASS!!!

BEWARE: Geller is a nice guy and is very helpful. However, if you're thinking about taking Astro for a GE, don't. The class is VERY challenging. Attendance is mandatory (for clarity on complex concepts and iclicker). He gives weekly HW assignments and CLAS is absolutely neccesary. Class average for midterm was a D-/C- and he didnt curve.

Geller is awesome. He's funny, teaches fairly well, and keeps the class light-hearted. The material may seem a bit daunting at first, but if you read the book and go to lecture, it's quite easy and interesting.

Geller was a good teacher. Material was a little hard but he made it much easier. Do the homeowrk and the class is fairly simple.

I found Geller very likable. He really seemed passionate about the subject. Although I found this class difficult, with concepts that were sometimes hard to grasp, I felt Geller was very fair with grading and his overall expectations. I did not find section very helpful.

Astro 1: Interesting class most of the time. Sections are optional and help sometimes. Pay more attention to conceptual ideas rather than math realated problems. Make sure to go to lecture because he does iClicker questions.

Class is easy if you pay attention and thoroughly complete homework. CLAS was very helpful. Geller is passionate and a good teacher. I am the opposite of a science student and I found his class doable and even interesting. He is laid back too, which is nice for a high-stress class

I had him for Astro. Great professor interested in the subject and makes his lectures very interesting. Important to attend every lecture. Understanding concepts is more important than knowing the math, although there's still math. CLAS helps. His tests are pretty straightforward, just study.

Geller is extremely helpful and clear. He strives to make certain that he is clear about what will be on the exams and gives a fair review before every test. It is very very important to go to class and take notes and later study the notes while doing homework. He is also very sociable and enjoys visits from students who are truthly interested.

Geller is a great lecturer who can really engage people in the material. He understands that many of the students are not physics majors, so he does make concessions for them. Tests are not easy, but are fair, as long as you do the homework and understand it.

I liked him up until he gave us a ridiculous final...and only ONE midterm???? Give us a break! I will be taking a different professor next quarter

I don't really enjoy physics so its made it hard for me to concentrate in this class. He is a very good teacher though and although I never passed a test, I still ended up passing the class. He curves when necessary. He's a nice and fun teacher. I, actually, enjoyed lectures.

His lectures are very useful, attend every lecture. His tests are fair and there is a curve for his class.

I really don't understand why he has good ratings. From the first day he set us up to fail, letting us know that we probably wouldn't get into grad school if we didn't pass the class. He's a horrible lecturer and I couldn't follow anything he said. Take CLAS.

Gellar is awesome. definitely reccommend taking him for the whole physics series. very fair and understanding- changing due dates if he feels we are too busy. Makes class very fun and interesting. In love with rockclimbing and has crazy hair... haha

he really cares about his students doing well, and tries hard to make the class interesting (and succeeds at this with his demonstrations!)there are weekly homework assignments online, 2 midterms and a final. he curves the tests so the average is around C+/B-. to do well make sure you go to lecture and UNDERSTAND the homework problems
