Dense Sets - 7

With our understanding of closures of sets, we are now able to define the idea of a dense set more precisely than what we’ve seen previously. We’ll discuss sets that are dense, not dense, and nowhere-dense in the reals. This leads us to our first meeting of Baire’s Theorem, another interesting perspective on the reals as a “large” infinite set.
