I'm John C. Baez. I'm a mathematical physicist. I teach in the math department at the University of California, Riverside and also work at the Centre for Quantum Technologies in Singapore.
I like quantum field theory, general relativity, n-categories, and other things that seem scary at first but turn out to be simple and beautiful when you understand them. Since I enjoy these things so much, I can't help but feel that everyone else will too. So, I like to explain stuff on my website. In 2003, I added a diary, where I can be a bit more random and diverse. In August 2006, I joined David Corfield and Urs Schreiber on a group blog: the n-Category Café.
Lately, however, I'm mainly concerned with developing a general theory of networks and getting mathematicians interested in applying their brilliance to the global ecological crisis.
