Math proofs vs physics "proofs" I'm a senior level physics major interested in taking a 400-level class in the math department for which I do not meet a prereq for (Graph Theory requires Intro to Abstract Math). I emailed the professor, and he stressed to me that a very important part of the class is doing math proofs, and that a physics major might not have the "mathematical sophistication" necessary to do well. Now, I have seen a lot of derivations in my upper level physics classes, but I have no idea how they compare to math proofs, or if they're even close to the same thing. For those that have taken both upper level physics and upper level math classes, will any of the skills translate from physics to math? Will the class be completely alien to me, or will I have a chance to understand it with some hard work?
