2/8/6- I Added a definition of int(A) so that our open set defintion would work, and I removed CZ's comment. In defining int(A) our class notes speak of B's intersection with M being a subset of A, for A being a subset of M. Is this necessary? Why include the M in the definition at all? -Aaron

2/9/6- Is the set of everything open? I remember talking about this in class, but forget how it went. The set of everything has an empty set as boundry, which it doesn't contain. So its open? Is that right? - Aaron
