Super mathematician

Daniel Tammet is an English writer, essayist, translator, and autistic savant gifted with a facility for mathematical calculations, sequence memory, and natural language learning. In his mind, Tammet says, each positive integer up to 10,000 has its own unique shape, color, texture and feel. He holds the European record for reciting pi from memory to 22,514 digits in five hours and nine minutes. Tammet also speaks ten languages.
