This is an in-depth look at the astonishing mental capabilities of Daniel Tammet, born in Britain, and from a young age able to do extraordinary calculations in his head. Skeptics have thrown a number of challenges at him, for instance testing his ability to recite to 22,500 decimal points the calculation of Pi, as well as learning a language in a week. Tammet, in his gentle unassuming way, has passed all the tests and offers this concluding statement about the phenomenon of savants: "The line between profound talent and profound disability is a surprisingly thin one."
