Shakuntala Devi [4th Nov 1939 ]

Shakuntala Devi is also a south India. She was born on
4th nov 1939 in our garden city Bangalore. This Indian legend is known as Indian Human Computer….
Once again all Indians and South Indians can feel proud about her…

Shakuntala Devi is an Indian calculating genius. Shakuntala Devi was born on November 4, 1939 in Bangalore,India.
Her father worked in a "Brahmin circus”. Her calculating gifts first demonstrated themselves while she was doing card tricks with her father when she was three.
They report she "beat" them by memorization of cards rather than by sleight of hand. By age six she demonstrated her calculation and memorization abilities at the University of Mysore. 
At the age of eight she had success at Annamalai University by doing the same. In 2006 she released a new book called In the
Wonderland of Numbers with Orient Paperbacks which talks about
a girl Neha and her fascination for numbers.



Achievements:

§  In 1977 In Dallas she competed with a computer to see who
give the cube root of 188138517 faster, she won. At university of
USA she was asked to give the 23rd root of
91674867692003915809866092758538016248310668014430862240712651642793465704086709659 32792057674808067900227830163549248523803357453169351119035965775473400756818688305 620821016129132845564895780158806771.
She answered in 50seconds. The answer is 546372891. It took a UNIVAC 1108 computer, full one minute (10 seconds more) to confirm that she was right after it was fed with 13000 instructions.
§  On June 18, 1980 she demonstrated the multiplication of two 13-digit numbers 7,686,369,774,870 x 2,465,099,745,779 picked at random by the Computer Department of Imperial College, London. She answered the question in 28 seconds. However, this time is more likely the time for dictating the answer (a 26-digit number) than the time for the mental calculation (the time of 28 seconds was quoted on her own website). Her correct answer was 18,947,668,177,995,426,462,773,730.
