I work on mathematical physics — which I interpret broadly as ‘math that could be of interest in physics, and physics that could be of interest in math’. I’ve spent a lot of time on $n$-categories and fundamental physics, but now I want to work on more practical things, too.

Why? I keep realizing more and more that our little planet is in deep trouble! The deep secrets of math and physics are endlessly engrossing — but they can wait, and other things can’t.

It’s working pretty well: check out all our members. But saving the planet is far from easy, so I really hope you join and help out.

Website and email

My website is here. It’s packed with interesting stuff on math and science.

My email address is baez@math.removethis.ucr.andthis.edu. Not really — but if you’re not smart enough to guess my real address from what I just said, I don’t want to hear from you.
