Amazing woman

Google is celebrating Shakuntala Devi 84th birthday. Being a curious person I looked her up on Wiki. Not only a human computer but she wrote about being married to a homosexual man and later called for decriminalisation in her book. The world has some interesting folks in it.

In 1977 in the USA she competed with a computer to see who could calculate the cube root of 188,132,517 faster (she won). That same year, at the Southern Methodist University she was asked to give the 23rd root of a 201-digit number; she answered in 50 seconds.[1][4] Her answer—546,372,891—was confirmed by calculations done at the U.S. Bureau of Standards by the Univac 1101 computer, for which a special program had to be written to perform such a large calculation.[11]

On June 18, 1980, she demonstrated the multiplication of two 13-digit numbers — 7,686,369,774,870 × 2,465,099,745,779 — picked at random by the Computer Department of Imperial College, London. She correctly answered 18,947,668,177,995,426,462,773,730 in 28 seconds.[2][3] This event is mentioned in the 1982 Guinness Book of Records.[2][3]
