Mental Calculator

150_alexis-lemaireAlexis Lemaire is a human calculator. He broke his own record for mental computing at the Science Museum in London by finding the 13th root of a 200-digit random number in 70.2 seconds.
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.

"It's quite remarkable to see it happen. A very small number of people have this extraordinary ability.

"I believe that it is the highest sum calculated mentally."
