I paint in oil and watercolor. Generally I paint on a very small scale.

People sometimes ask why I don't produce mathematically themed art. The reason is that painting is something I do to obtain release from the logical rigors of mathematics. In his "Ode on a Grecian Urn," Keats famously wrote, "Beauty is truth, truth beauty." This is correct, I think, but imprecise. Mathematics concerns the beauty of truth, whereas art concerns the truth of beauty.

All that said, I do in fact produce some mathematical art, but it seems more appropriate somehow to make it digitally, through programming and algorithms; the pleasure I obtain from creating such pieces is quite distinct from my enjoyment of painting.
