New Delhi: Today Google is celebrating 84th birth anniversary of the legendary Indian mathematics wizard Shakuntala Devi who made complex mental calculations as a child prodigy and known as the world's fastest ‘human computer'. Shakuntala Devi was born on November 4, 1929 in Bangalore.
She demonstrated her calculation skills in her first major public performance at the age of six in University of Mysore.
She held a Guinness World Record for her lightning-speed calculations. Among her distinctions was her ability to, given a date in the last century, mentally ascertain the day.
In 1977, she calculated the 23rd root of a 201-digit number in just 50 seconds. In 1980, she multiplied two 13-digit numbers given to her randomly by the Computer Department of Imperial College, London.
