This delightful animation by Stefan Nadelman depicts “the additive evolution of prime numbers“, set to Lost Lander’s song “Wonderful World”: http://www.youtube.com/watch?v=TZkQ65WAa2Q. (If you haven’t watched it, you may want to do so before reading the rest of the question.) Counting $1$ as prime, the video shows a prime number growing up to $23$ by absorbing […]

I’ve been giving a public talk about Art and Mathematics for a few years now as part of my University’s outreach program. Audience members are usually well-educated but may not have much knowledge of math. I’ve been concentrating on explaining Richard Taylor’s analysis of Jackson Pollock’s work using fractal dimension, but I’m looking to revise […]

You are probably familiar with “mirror anamorphosis,” the rendering in a painting of a distorted figure that can be undistorted by viewing in an appropriately tilted or curved mirror. The skull in the Hans Holbein painting (the streak at bottom center) is perhaps the most famous example: (Image from Wikipedia article.) My question is: […]
