John Baez

John Baez talks about string theory and why more physicists should concentrate on the other approaches in his latest "This Week's Finds in Mathematical Physics" ([livejournal.com profile] john_baez):

The last part where he talks about "hill climbing" vs. "valley crossing" approaches to physics is especially interesting.

He also runs a very cool group blog together with David Corfield and Urs Schreiber called The n-Category Café. The latest entry is about a new attempt to formulate a topos foundation for theories of physics by Andreas Döring and Chris Isham.
