This class is really really easy and really really boring. The only grades is from homework that is due once a week that is not hard at all (just trying to find the answers online) that he grades for completion and a PowerPoint project that you can do on whatever you want in relation to space. The actual class is rather pointless and you just have to sit thru 2 hours and pay attention. Mr. Celli is extremely intelligent and knows a lot about a lot of things and he is a nice guy too.

Very easy class but kind of boring, especially if you don't actively participate in the class discussions. Celli seems knowledgable about the material. For the grading, every week you get a "problem set" which is extremely easy, and you have to do one in-class presentation. Everyone who turns in all the assignments gets an A.

I LOVE THIS CLASS SO MUCH

This is a very easy class, but it can be rather boring. If you're really interested in cosmology and relativity and quantum mechanics, it's great, but for most people, you will find it difficult to understand and to pay attention. However, it is not graded based on your understanding of the material, so you can still get an A if you have no idea what's going on. Grade is based on weekly HW (graded for completion) and final PPT presentation or paper on topic of your choice.
