World's best mathlete

What?!?

Weird term for this guy, but then, he's a weird unique guy.

LONDON (AFP) - The world's fastest human calculator on Tuesday broke his own record for working out a 200-digit number using nothing but brain power to produce the answer in just over 70 seconds.

Alexis Lemaire, a 27-year-old Frenchman, correctly calculated the 13th root of a random 200-digit number from a possible 393 trillion answers.

The so-called 'mathlete' produced the answer of 2,407,899,893,032,210 in 70.2 seconds, beating his previous record of 72.4 seconds, at London's Science Museum.

A computer was used to produce a random 200-digit number before he sat down to calculate the answer in his head.
...
Lemaire, who attends the University of Reims in northern France, began demonstrating his prowess by finding the 13th root of a random 100-digit number but gave up trying to improve his performance when he calculated an answer in under four seconds in 2004.

Like an athlete, he trains his brain daily for the far harder task of finding the 13th root of 200-digit numbers.

Just try to fathom that. Try to comprehend finding a root, much less the 13th root, of a 200-digit number. I can't even fathom a 200-digit number, much less its root!!

I suddenly feel very mentally small.
