I'm a math major and a professor in a philosophy class I was in recently discussed this as an example of a definition or assumption that mathemeticians use. My question is, since this is true for lower level math courses (I've only taken up to Lin. Alg.), is it still a definition, or has a proof been offered for it?

(Again, this is question has mostly a kind of a graduate-level audience. Please don't respond with some stupid crap about how 1+1 can't equal 3, therefore it's true, or anything like that.)

Ok. So, at 2am daylight savings ends. Do I set my clock back to 1 am or do I put it at 3 am? I have to be at work at 7am.... so would I really show up at 6 or 8 actual time. (before changing the clock) Sorry, it's confusing, but I don't know which way to change my clock. If it's 7.... Should I turn it to 6 or 8? Thanks

I live in New York. I hate the cold more than ANYTHING. I hate it so much I want to cry every day because I can't be outside or else I will freeze. I hate it. I want to move to Aulstralia or New Zealand soooo badly. How can I be happy with snow and cold? It just makes me depressed to look outside at bare trees and dead plants. I miss the spring and summer veryyyy much.
