Daniel Tammet holds the European record for reciting the first 22,514 digits of the mathematical constant
pi.
From the May, 2009 issue of Scientific American Mind, p.61-63
I am unusually creative - from visualizing numerical landscapes composed of random strings of digits to the invention
of my own words and concepts in numerous languages. Where does this creativity come from?
In most people, the brain's major functions are performed separately and not allowed to interfere with one another. Scientists
have found that in some brain disorders, however, including autism and epilepsy, cross-communication can occur between normally
distinct brain regions.
My theory is that rare forms of creative imagination are the result of an extraordinary convergence of normally disconnected
thoughts, memories, feelings and ideas. Indeed, such hyperconnectivity within the brain may well lie at the heart
of all forms of exceptional creativity.
Various studies have long demonstrated that being able to visualize information makes it easier to remember.
Where you might see an endless string of random digits when looking at the decimals of pi, my mind is able to "chunk"
groups of these numbers spontaneously into meaningful visual images that constitute their own hierarchy of associations.
