is a professor of mathematics at U.C. Riverside who also works at the Centre for Quantum Technologies
in Singapore. Until recently he worked on higher category theory and quantum gravity. His internet column This Week's Finds
dates back to to 1993 and is sometimes called the world's first blog.
In 2010, concerned about climate change and the future of the planet, he switched to working on more practical topics and started the Azimuth Project
, an international collaboration to create a focal point for scientists and engineers interested in saving the planet. But Baez continues to enjoy explaining mathematics, and Visual Insight
is one way to do that.
