## The mathematics of human knots

Have you ever played “human knot”? It seems to be a common icebreaker/team-building sort of exercise (just do a Google search for “human knot” and you’ll find quite a few pages discussing it). Everyone stands in a circle, then reaches … Continue reading

## Hyperbinary conjecture seeking proof for a good time, long walks on the beach

Here’s the latest progress on the hyperbinary sequence. We’re trying to figure out the inverse relation of the function : given a particular number , where does it occur in the hyperbinary sequence? That is, what are the values of … Continue reading

## New bookshelf entry: The Annotated Turing

For my birthday I got, among other things, a copy of The Annotated Turing: A Guided Tour Through Alan Turing’s Historic Paper on Computability and the Turing Machine, by Charles Petzold. I haven’t finished reading it yet, but so far, … Continue reading

## Fun "mathemagic" video

For something on the lighter side, here’s a fun video that I’ve seen linked to from a number of places. It’s a video of Arthur Benjamin, a math professor at Harvey Mudd College, performing a fifteen-minute “mathemagics” show. He multiplies … Continue reading
