Lemaire
[Dec 12]LONDON, UK--"Mathlete" Alexis Lemaire
,
27, found the answer to the 13th root of a random 200-digit number
in 70.2 seconds by sheer brain power - beating his own world record
of 72.4 seconds he set in November.

He
used a computer package which randomly generated a 200-digit number.
As soon as the number appeared, he began to calculate its 13th root.
When he had the answer, he typed it into the computer, which told
him he had the right answer and how fast he made his calculation.
Jane Wess, curator of mathematics at the London Science
Museum said: “He sat down and it was all very quiet - and all of
a sudden he amazingly just cracked it. “He seems to have a large
memory and he’s made this his life’s ambition. It’s quite remarkable
to see it happen. "A very small number of people have this extraordinary
ability; nowadays there is only a handful. “I believe that it is
the highest sum calculated mentally.”

Nowadays he tries to find the 13th root of a random
200-digit number to train his brain.
Lemaire broke the record in the Science Museum’s History
of Computing galley. It is the home of Charles Babbage’s Difference
Engine No.2, the world’s first successful mechanical calculator,
designed in the 1840s.
Lemaire had said before he smashed the world record:
“I am pleased to be able to make my latest world-record attempt
at the Science Museum. “I have been training very hard and I am
confident I can break the world record.”
