PAGE 2 Autistic genius - Daniel Tammet On the outside, 31-year- old Daniel Tammet is an unremarkable young man. But behind Tam- met's bookish exterior lies a superhuman gift: one of the most extraordinary brains our planet has ever seen. He is a mathematical genius, capa- ble of astro- nomical calcu- lations in the blink of an eye. And he's a gift- ed linguist, speaking nine languages, including one he created called Manti. Tammet says he was born with the ability to experi- ence numbers in an ex- ceptionally vivid way. "The numbers are moving in my mind," he says. "Sometimes they're fast, sometimes they're slow. Sometimes they're dark. Sometimes they're bright. That emotion, that motion, that texture will be highly memorable for me." The phenomenon is called synaesthesia, a mixture of the senses that results in a heightened sensory experience. Tam- met is able to see and feel numbers. In his mind's eye, every digit from zero to 10,000 is pictured as a 3-dimensional shape with a unique colour and tex- ture. For example, he says, the number fifteen is white, yellow, lumpy and round. Synaesthesia occurs when DIG IT AL MAGAZINE regions of the brain asso- ciated with different abili- ties are able to form unu- sual connections. In most people's brains, the recognition of colours, which is longer a little bit like an hourglass. And there's a space that's cre- ated in between. That shape is the solution. 6,943!" Tammet first discov- ered his mathemati- cal abilities as a child, the eldest of nine children in his family in England. the ability to manipulate numbers, or language capacity all work differ- ently in separate parts, and the information is generally kept divided to prevent information over- load. But in synesthetes, the brain communicates between the regions. Tammet doesn't need a calculator to solve expo- nential math problems such as 27 to the 7th pow- er -- that's 27 multiplied by itself seven times -- he'll come up with the answer, 10,460,353,203, in a few seconds. Tammet visualizes num- bers in their unique forms and then melds them to- gether to create a new image for the solution. When asked to multiply 53 by 131, he explains the solution in shapes and textures: "Fifty-three, which is round, very round...and larger at the bottom. Then you've got another number 131, "I learned to count, like anyone else, at a young age, and when I did I would see colours," he said. "I would see pictures in my mind. I assumed at the time that everyone saw numbers as I did." Tammet didn't do math as it was taught in school. Instead, the answers just came to him. It was Tammet's obses- sion with numbers that led to an incredible feat on March 14, 2004, known as Pi Day, when Tammet broke the European rec- ord for reciting the num- ber Pi from memory. Pi, the ratio a circle's cir- cumference to its diame- ter is considered an "irrational" number in mathematics because it does not end. You may be able to remember the first few digits -- 3.14159 - - but not more. Tammet says he only read through the digits once and was able to re- member 22,514 of them. After a couple weeks to practice reciting the num- bers back, in order, it
