Freeman J. Dyson (physicist)

Some quotes: "Superstrings and butterflies are examples illustrating two different aspects of the universe and two different notions of beauty. Butterflies are at the extreme of concreteness, superstrings at the extreme of abstraction. They mark the extreme limits of the territory over which science claims jurisdiction. Both are, in their different ways, beautiful. Both are, from a scientific point of view, poorly understood. Scientifically speaking, a butterfly is as least as mysterious as a superstring. Almost all the things scientists think and dream about are mysterious."
