Identify him. This one is probably a bit too geeky even by my standards.Answer: The man is British mathematician and physicist Roger Penrose. He is standing on a floor tiled with an aperiodic tiling pattern that he discovered in the 70s. While it is trivial to tile a space with periodic tilings (square tiles for example), Penrose found a family of aperiodic tiles that have no translational symmetry. Raghu, Rajesh, hotmanoj and Amresh got it. Well done.

Roger Penrose. The tiles around him show the famous "Penrose tiling" which is a way of tesselating an infinite plane using non-periodic tiles.

@Raghu: The pic is from the wiki page for Penrose tilings.
