Where does Pac-Man live?
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 [...]

Finding a good question
I just met with my advisor, Sandor Kovacs. Meeting with him is great, and I walk out excited to get to work. No exception today, but my work feels particularly slippery at the moment. The reason is that I don’t yet have a good question. [...]
