Search Engine Giant Google has paid tribute to renowned Indian Mathematician Shakuntala Devi (also called Human Computer) by incorporating a doodle on its Homepage today, marking her 84th Birthday. Devi passed away in April this year at Bangalore.
Shakuntala Devi was regarded a a Rare Human Genius
The Black and White Doodle has a portrait of Shakuntala Devi with the word Google written in LED Styled Display, similar to that in Calculators. This is quite reasonable because Ms. Devi held a Guinness World Record for her lightning-speed calculations.
In 1977 in USA she competed with a computer to see who gives the cube root of 188132517 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. 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.
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.  This event is mentioned in the 1982 Guinness Book of Records.
In 1988,  she visited US to have her abilities studied by Arthur Jensen, a professor of psychology at the University of California, Berkeley. Jensen tested her performance at several tasks, including the calculations of large numbers; Examples of the problems presented to Devi were calculating the cube root of 61,629,875, and the seventh root of 170,859,375 Jensen reported that Devi was able to provide the solution to the aforementioned problems (the answers being 395 and 15 respectively) before Jensen was able to copy them down in his notebook.  Jensen published his findings in the academic journal Intelligence in 1990.
Due to her extra-ordinary ability in Calculations, she was given the title of Human Computer and Mental Calculator by fans.
Born in Bangalore in  1929, to a Circus Artist, Shakuntala was a prodigy since Childhood. By age six she demonstrated her calculation and memorization abilities at the University of Mysore.
Professionally, she was a Mathematician, wrote several books on Mathematics, Computing, Riddles and Novels. She also practiced Astrology in part times.
She was married to an IAS Officer Paritosh Bannerji, with whom she had a daughter.
She passed away on April 21, 2013 at Bangalore after being admitted to Hospital for 2 weeks owing to respiratory problems and complications of the heart and kidneys.
