Hello! This is John Baez’s new blog.
I’m a mathematical physicist. I teach at U.C. Riverside, but tonight my wife and I are flying to Singapore. For two years she’ll be teaching at the philosophy department of the National University of Singapore, and I’ll be working at the Centre for Quantum Technologies. This will be a good time to change gears and try something new. I’ve been working 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 the Earth is in serious trouble! The deep secrets of math and physics are endlessly engrossing — but they can wait, and other things can’t.
I hope we talk about many things here: from math to physics to earth science, biology, computer science, economics, and the technologies of today and tomorrow – but in general, centered around the theme of what scientists can do to help save the planet.
That sounds pretty ambitious, verging on pompous. Right now, though, it’s midnight and I’m sitting in the airport lounge in Los Angeles waiting for a 1:40 am flight to Hong Kong, and then a connection to Singapore. So, that’s all for now. I just felt like kicking off this new blog…
