Title: “The Most Interesting Dimension”

 

Description: At least on the scale of classical physics, we inhabit a four dimensional
world (three dimensions of space and one of time).  I’m going to explain why it is that
a four dimensional world is the most interesting possible world for a topologist.  Four
dimensions give just enough room for some interesting geometry to get “wound up”, but
in any higher dimension there is so much room that it can get “unwound” again.
