This talk was the first of the Leverhulme Lectures, for the Leverhulme Visiting Professorship scheme.

In this century, progress in fundamental physics has been slow. The Large Hadron Collider hasn't yet found any surprises, attempts to directly detect dark matter have been unsuccessful, string theory hasn't made any successful predictions, and nobody really knows what to do about any of this. But there is no shortage of problems, and clues. After a quick review of our best theories of physics so far - general relativity and the Standard Model - Baez will list some of the main open problems.
