In physics, Hofstadter's butterfly is a mathematical object describing the theorised behaviour of electrons in a magnetic field.
 It was discovered in 1976 by Douglas Hofstadter, who later abandoned physics research and became notable as a cognitive scientist and author.
 It takes its name from its visual resemblance to a butterfly.
 It is a fractal structure and as such it shows self-similarity, meaning that small fragments of the structure contain a (distorted) copy of the entire structure.
 It is one of the rare non-random fractal structures discovered in physics, along with KAM theorem.

Question: Which literature prize did the scientist who discovered Hofstadter's butterfly win ?
Answer: the Pulitzer Prize
