Exhibit A: Mathlete Breaks Own Record:
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.
The museum’s curator of mathematics, Jane Wess, said: “He sat down and it was all very quiet — and all of a sudden he amazingly just cracked it.
“I believe that it is the highest sum calculated mentally.”
