Born in Bangalore (India), Shakuntala Devi was, from a young age, a prodigy in mathematics. Often called the Human Computer, Shakuntala had calculation capabilities only seen on computers.

In 1977, Shakuntala was able to mentally calculate the twenty-third root of a number of more than 200 digits in less than one minute. At the time, it was 12 seconds faster than the most powerful computers available at that time. In the same year, Shakuntala was able to mentally calculate the cube root of 188,132,517 faster than a computer.

But their deeds do not stop there. Three years later, Shakuntala mentally calculated the product of two numbers chosen randomly, each with 13 digits.

The true genius of maths mental calculation died last year, 2013, in April.
