What do I need to know before I can study Cosmology. I think I'm going to read this text: http://www.amazon.com/Cosmology-Ste...6822/ref=sr_1_1?ie=UTF8&qid=1328767963&sr=8-1 Cosmology by Steven Weinberg. I'm going to read this College Physics text first by Serway http://www.amazon.com/College-Physi...=sr_1_1?s=books&ie=UTF8&qid=1328767998&sr=1-1 And I will have a good grasp of calculus soon. What other math and physics do I need to know? Also what math does Cosmology employ most?
