Mathematics, Symmetry and Reality

Physicists Max Tegmark (MIT) and Dave Goldberg (Drexel) talk about their books ("Our Mathematical Universe: My Quest for the Ultimate Nature of Reality" and "The Universe in the Rearview Mirror: How Hidden Symmetries Shape Reality", respectively) at the Free Library.

I probably won't be able to attend - especially if I see Goldberg on the previous evening, but I thought it might be of interest to the group.
