Language Without Numbers

"An Amazonian language with only 300 speakers has no word to express the concept of "one" or any other specific number, according to a new study from an MIT-led team.

The team, led by MIT professor of brain and cognitive sciences Edward Gibson, found that members of the Piraha tribe in remote northwestern Brazil use language to express relative quantities such as "some" and "more," but not precise numbers..."

The Boy With The Incredible Brain

"In his mind, he says, each integer up to 10,000 has its own unique shape, colour, texture and feel.

He can intuitively "see" results of calculations as synesthesic landscapes without using conscious mental effort, and that he can "sense" whether a number is prime or composite.

He has described his visual image of 289 as particularly ugly, as particularly attractive, and pi as beautiful. 6 apparently has no distinct image. Tammet not only verbally describes these visions, but has also created artwork: a watercolour painting of Pi.

Tammet also holds the European record for reciting pi to 22,514 digits in five hours and nine minutes.

He speaks eleven languages including English, French, Finnish, German, Spanish, Lithuanian, Romanian, Estonian, Icelandic, Welsh and Esperanto."
