Abstract: 

At my previous talk, we defined and topoligized profinite groups as the inverse limit of finite groups. Today we will give the inverse limit construction of the p-adic integers and explore the p-adic metric. Results will include a one-line irrationality proof, a homeomorphism to the Cantor set missing a point, and the consequences of an ultrametric.
