Visual Insight

John Baez

August 13, 2013 - January 1, 2017

For several years I ran a blog for the American Mathematical Society called Visual Insight. The idea is that it was a place to share striking images that help explain advanced topics in mathematics. I put out two issues a month. The blog is still there, but I've decided to copy the posts here. As time goes on I may make them easier to navigate. Here they are:
