Born in a poor family, Shakuntala had to drop out of school because her father, a circus worker, could not afford the monthly school fee of Rs 2.
Shakuntala Devi, born on 4 November 1929, was an Indian writer who was famously known as ‘mental calculator’ & ‘human computer’. As child prodigy, she was even named in the 1982 edition of The Guinness Book of World Records.
During her childhood, her father was surprised to see how Shakuntala could win game of cards every time. He found out that she was memorizing all the card numbers and their sequence. She was able to predict the sequence of cards in the subsequent rounds of the game and thus wait to pick cards strategically.
Therefore, he decided to teach her mathematical operations like multiplication, division & square root. Later she started accompanying him to circus and did shows mesmerizing everyone. At the age of 6, she gave her first major show at Mysore University. After that, tours to Europe and Americas became common.
There are more such stories:
- In 1980 at the Computer Department of Imperial College, London, Shakuntala demonstrated the multiplication of two 13-digit numbers 7,686,369,774,870 × 2,465,099,745,779. She calculated the answer 18,947,668,177,995,426,462,773,730 in 28 seconds. This was the event mentioned in the Guinness Book of Records.
- In 1988, she calculated the cube root of 61,629,875, and the seventh root of 170,859,375 without writing it down or using a calculator which was noticed by the famous professor Arthur Jensen. These findings were published in the academic journal Intelligence in 1990.
In 1977, she even wrote a book on homosexuality called ‘The World of Homosexuals’, which is considered to be the first study of homosexuality in India. She once said she studied this topic closely after she got married to a homosexual man.
In 2013, Shakuntala Devi passed away at the age of 83. Her books were all about mathematics, puzzles, and astrology. To name a couple of them: ‘Fun with Numbers’ and ‘Puzzles to Puzzle You’. We feel so proud while writing her story! 🙂
