During the weekend I have finished the book “Born on a Blue Day” by Daniel Tammet
This unique first-person story opens a window into the mind of a 27-year-old autistic savant with Asperger’s syndrome.
Daniel is capable of incredible feats of memorization and mental calculation. Besides being able to effortlessly multiply and divide huge sums in his head with the speed and accuracy of a computer; Daniel, learned Icelandic in a single week and recited the number Pi up to the 22,514 digit, breaking the European record (3-14-2004 Pi Day)
Daniel also experiences synesthesia which is an unusual neurological syndrome that enables him to experience numbers and words as shapes, colors, textures and motions.
“I was born on January 31, 1979 — a Wednesday. I know it was a Wednesday, because the date is blue in my mind and Wednesdays are always blue, like the number 9 or the sound of loud voices arguing. I like my birth date; because of the way I’m able to visualize most of the numbers in it as smooth and round shapes, similar to pebbles on a beach. That’s because they are prime numbers: 31, 19, 197, 97, 79 and 1979 are all divisible only by themselves and 1. I can recognize every prime up to 9,973 by their “pebble-like” quality. It’s just the way my brain works.”
“The number 11 is friendly and 5 is loud, whereas 4 is both shy and quiet — it’s my favorite number, perhaps because it reminds me of myself. Some are big — 23, 667, 1,179 — while others are small: 6, 13, 581. Some are beautiful, like 333, and some are ugly, like 289″
“One of the most common questions I was asked … was: Why learn a number like pi to so many decimal places? The answer I gave then as I do now is that pi is for me an extremely beautiful and utterly unique thing. Like The Mona Lisa or a Mozart symphony, pi is its own reason for loving it.“
Daniel stated in his book that it wasn’t easy to find enough (digits) Pi in the web, so inspired from his book, I have created an online “backup”* for the first 10 million digits of Pi @ http://pi.karmona.com
* During August 1995, Dr.Takahashi and Dr. Y.Kanada have managed to calculate pi up to 4,294,960,000 decimal digits (current world record) using a supercomputer at the University of Tokyo – The University ftp server was Daniel’s (& my backup) source…
