This is actually a fractal picture! There’s a gallery of them here. Gorgeous.

Here’s a question I’ve always liked: what kind of world does Pac-Man on? We know we live on a sphere, or course, or something close to it. But we often imagine our world on [...]

The other day a friend related a math nightmare. She was in a prison-like compound. People guarded the exits, and they wouldn’t let her out until she solved a calculus problem. She couldn’t ever do it, and her teeth started to fall [...]

Link: Mathematical Flimflam One thing that’s always struck me is how mathematics has been interpreted by so many people in so many contexts as a direct conduit to God’s thoughts. This link is a modern manifestation of that—but sadly [...]

Just had a fun little tutoring session with a new student. (How could it surprise you that I tutor?) She strikes me, happily, as one of the many people who have a decent aptitude for math but, sadly, don’t like it much and don’t think [...]
