In seven minutes my Harvard ID should not, if what they threaten is true, allow me into Leverett any longer. Even so, I can’t muster the necessary fear that would otherwise inspire me to get the last few things out of my room so the next kid can take it. Instead, I’d like to post this very silly graphic explaining the three possible geometries of the universe without much introduction or explanation. Notice that it is unduly funny. [I stole it from NASA’s WMAP page.]
