John Baez does network theory

I love John Baez’s blog that was a blog before we called things blogs, This Week’s Finds. (He also writes the Azimuth blog, linked in our blogroll below. And I tip my hat to my father-in-law, who first introduced me to Baez’s blog.)

Baez is now writing on network theory. Baez typically focuses on math and physics, but this series is great for biologists:

I wish there were a branch of mathematics—in my dreams I call it green mathematics—that would interact with biology and ecology just as fruitfully as traditional mathematics interacts with physics. If the 20th century was the century of physics, while the 21st is the century of biology, shouldn’t mathematics change too? As we struggle to understand and improve humanity’s interaction with the biosphere, shouldn’t mathematicians have some role to play?
