Today's Google doodle pays tribute to an Indian woman who could perform superhuman mathematical feats, such as finding the 23rd root of a 201-digit number in just 50 seconds. Shakuntala Devi, nicknamed the "Human Computer," died earlier this year at age 83 in her hometown of Bangalore. Monday (Nov. 4) would have been her 84th birthday.
Devi's father was a trapeze artist and lion tamer in the circus who started arranging road shows to demonstrate his young daughter's incredible calculating skills. Throughout her lifetime, she toured the world, stunning audiences and beating computers. Devi landed in the Guinness Book of World Records in 1982 after acing a daunting feat: multiplying two 13-digit numbers in her head, and reciting the 26-digit answer in 28 seconds flat. (That problem, by the way, was 7,686,369,774,870 x 2,465,099,745,779. The answer was 18,947,668,177,995,426,462,773,730.)
