Talk:Metric space

From AoPSWiki

Amazingly enough, I can't think of a good way to "intuitively" explain why a metric space should possess symmetry (yet, it seems the most obvious of the properties). Anyone care to add it in? We should also create the sections on Euclidean and Discrete metrics (p-adic metrics too? Not sure if that applies much to problem solving though...). ~eyefragment
