Daniel Tammet is a 27 year-old math and memory wizard. He can calculate numbers to hundreds of decimal points in seconds and learn new languages in a week. He is a savant... with a difference. Unlike most savants, he shows no obvious mental disability, and most importantly, he can describe his own thought process.

Daniel Tammet first came to worldwide attention in March 2004 on International Pi Day (3/14, of course) when he recited, from memory, Pi to 22,514 decimal places. It took over five hours and set a new European record. The event, which Daniel named "Pi in the Sky", coincided with Einstein's birthday and took place in front of Einstein's blackboard at the Museum of the History of Science in Oxford, England.
