General Public Lectures
MoMath – “Fractal Beauty” – July 2015
It suddenly struck me that that tiny pea, pretty and blue, was the Earth. I put up my thumb and shut one eye, and my thumb blotted out the planet Earth. I didn’t feel like a giant. I felt very, very small.

The airman’s earth, if free men make it, will be truly round: a globe in practice, not in theory.
