With all due respect to Stephen Hawking, Bill Gates, and any living Nobel laureates, the most remarkable mind on the planet just might belong to Daniel Tammet, the 27-year-old author of Born on a Blue Day. One of only a handful of autistic savants (like Dustin Hoffman’s character in Rain Man), he’s been gifted with a phenomenal facility in math (memorizing pi to more than 22,000 places) and languages (conversant in at least 10). Also born with a rare neurogical condition called synesthesia, he perceives numbers and letters as shapes and colors (hence the title). Tammet displays a surprising level of sensitivity — and a refreshing lack of sentimentality — in an account that inspires even as it astonishes.
