(200 words excerpt, click title or image to see full post)

A short two-person dance, with a twist. Or more accurately, a shear: time is remapped so that there is a delay that increases as you move from the top of the frame down to the bottom. Or in math: (x’, y’, t’) = (x, y, t – y), in some units. Via Terence Tao and Alex Fink.
