Shakuntala Devi was an Indian writer and mental calculator , popularly known as the “human computer”.  A child prodigy , her talents eventually earned her a place in the 1982 edition of
The Guinness Book of World Records ” . As a writer, Devi wrote a number of books, including novels as well as texts about mathematics, puzzles, and astrology. 

EARLY LIFE :-
              Shakuntala Devi was born in Bengaluru , India to an orthodox Kannada Brahmin family. Her father rebelled against becoming a temple priest and instead joined a  circus where he worked as a trapeze artist, lion tamer,
tightrope walker and magician . He discovered his daughter’s ability to memorise numbers while teaching her a card trick when she was about three years old. Her father left the circus and took her on road shows that displayed her ability at calculation.  She did this without any formal education.  By the age of six she demonstrated her calculation and memorisation abilities at the University of Mysore .  In 1944, Devi moved to London with her father.

MENTAL CALCULATION :-
    Devi travelled the world demonstrating her arithmetic talents, including a tour of Europe in 1950 and a performance in New York City in 1976. In 1988, she travelled to the US to have her abilities studied by Arthur Jensen, a professor of psychology at the University of California, Berkeley. Jensen tested her performance of several tasks, including the calculation of large numbers.
Examples of the problems presented to Devi included calculating the cube root of 61,629,875 and the seventh root of 170,859,375. Jensen reported that Devi provided the solution to the aforementioned problems (395 and 15, respectively) before Jensen could copy them down in his notebook. Jensen published his findings in the academic journal Intelligence in 1990.  In 1977, at Southern Methodist University , she was asked to give the 23rd root of a 201-digit number; she answered in 50 second  Her answer—546,372,891 was confirmed by calculations done at the US Bureau of Standards by the UNIVAC 1101 computer, for which a special program had to be written to perform such a large calculation.
On 18 June 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 . Writer Steven Smith states that the result is “so far superior to anything
previously reported that it can only be described as unbelievable”.
      
In addition to her work as a mental calculator, Devi was an astrologer and an author of several books, including
cookbooks and novels.

LAST PART OF LIFE :-
      In April 2013, Devi was admitted to a hospital in Bengaluru with respiratory problems. Over the following two weeks she suffered from complications of
the heart and kidneys. She died in the hospital on 21 April 2013. She was 83 years old then.  She is survived by her daughter, Anupama Banerji.
On 4 November 2013, Devi was honoured with a Google Doodle for what would have been her 84th birthday.
