Shakuntala Devi was a calculating child prodigy who was born on November 4, 1939 in Bangalore, India.  Her calculating talents first known while she was doing card tricks with her father when she was three.  Shakuntala Devi was born in Bangalore, India to an orthodox  priestly Brahmin family.  At the age of three she manifested an extraordinary love for numbers and by the time she was five years old, Shakuntala became an expert in Complex Mental Arithmetic. With a divine skill in numbers from the age of three, she has been stunning the whole world with her uncanny skill in computing the most intricate problems mentally, even quicker than the highly sophisticated computers in the world.


Hailed as a “Human Computer” because of her extraordinary talents in solving complex mathematical problems.  Shakuntala Devi also found her place in the Guinness Book of World Records.  She has astonished scientists across the world by her capacity to solve mathematical problems in a jiffy without any mechanical aid.  Usually these complex mathematical calculations are carried at lightning speed on computers.  It can be said that Shakuntala Devi is Blessed with God’s Gift.  Apart from mathematical problems, she is utilizing her amazing talent in the field of astrology.



She was born with this extraordinary talent as from the very childhood; she used to solve arithmetical problems orally in no time.   Manifested an extraordinary love for numbers at the age of 3, she became an expert in complex mental arithmetic at 5.  She had not even the formal education.  On the other hand her father took her to different places to exhibit her prowess.  Soon, her reputation spread all over the country and finally her fame crossed the borders of the country.  Today, she is acclaimed as an accomplished mathematician.  By age six she demonst rated her calculation and memorization abilities at the University of Mysore. At the age of eight she performed her unique gift at the Annamalai University in Southern India and the then Vice Chancellor of the University Rt Hon. V.S. Srinivasa Shastriar P.C., CH, LX.D. called her a “living wonder”. Around the same time she performed in the Osmania University in Hyderabad and the Vizag University. Soon Shakuntala, who displayed her talents to gatherings of distinguished people all over India, came to be acclaimed as a Child Prodigy.   



BBC London, invited her to give her demonstration on television.  Many other countries also invited her.  She was asked very complex questions, solvable by computers only.  But, Shakuntala Devi never faltered and gave the answer after mental calculations.  On June 18, 1980, Shakuntala Devi gave a product of two thirteen-digit figures after multiplying them within only 28 seconds.  The figures were 1894766817799 and 5426462773730, asked by the computer department of Imperial College, London.  In 1976, she amazed the US scientists by giving immediate answers to complex arithmetical problems by her conventional approach.  Shakuntala Devi has delighted world audiences with her lightning-fast computation and her infectious enthusiasm and love for numbers.

Still in her early ages, Shakuntala sailed to Europe in 1950. In London on the 5th of October, 1950, the BBC presented Shakuntala to the viewers of Great Britain. Shakuntala gave quick answers to problems posed by the BBC, but when further questions were given, she challenged the problem as set and said it was worked out wrongly. Mr. Leslie Mitchell, the BBC's interviewer did some quick checking and confessed that Shakuntala was right and the BBC wrong!



At the University of Rome one of her answers to the problems was found to be wrong by the calculating machine, but after re-checking it was found that the machine had made the mistake and not Shakuntala!
In Sydney, Australia, Shakuntala matched her wits against their most sophisticated Computer at that time, "UTECOM" of the University of New South Wales. Questions were set by the then well known Professors Mr. R.G. Smart and Mr. Barry Thornton, the Chief Mathematicians, Seconds before the questions were fed to the computer, Shakuntala had the answers. "It's frightening" remarked Mr. Thornton. Throughout her tours around the world, Shakuntala has performed in Universities, Colleges, Schools, Theatres, and on Television with great distinction. In England on the 27th of September 1973, Shakuntala appeared on the BBC programme "Nationwide" with the distinguished Bob Wellings on the popular ITV programme "Today" and the Televiewers of Great Britain were left in a daze by the "mind-collapsing" performance of Shakuntala Devi. She has received accolades and high letters of appreciation from all these Universities. Shakuntala Devi has also performed in the World Bank - Washington D.C. and the United Nation in the year 1977.

CHANAKYA

  Name           :  Chanakya

 

 

Country        :  India

Period           :  Born :  350 B.C.E.                   

                      :  Died  :  275 B.C.E.

Age               :  75  years

Alma Mater : Takshashila
Profession    : Teacher, Advisor of Chandragupta Maurya
Famous for   : Foundation for Mauryan Empire
Teachings     : Artha Shaastra, Ethics of Political Rules (Chanakya Neeti)

 

   

Chanakya is famous in history of India as a sage-like person who by his political shrewdness and expediency helped in the establishment of the mighty Mauryan empire.  Chanakya was wise, clever, foresighted, determined and deeply read in economics, diplomacy and politics. 

 


There is a legend that Chanakya was once invited to the court of the Nanda rulers of Magadha where he was insulted.  Chanakya took a vow to cause the downfall of the Nanda dynasty.  With the help of a brave and capable general, Chandragupta, he succeeded in fulfilling his vow and founded a new Mauryan dynasty in Magadha.

 

 

Chanakya expelled the Greek invaders from India with his help again.  Chanakya served as a friend, philosopher, and guide to Chandragupta Maurya.  Chanakya is alsobelieved to be the author of  "Artha Shaastra", the classical Indian treatise on statecraft.  It lays down rules of government and also gives a detailed account of the contemporary state administration.




Chanakya was born in a poor Brahmin family of Takshashila.  His real name was Vishnugupta.  Chanakya is also known as Kautilya, because of his "Kut-Niti" or diplomacy.  He was educated at Takshashila, a great educational centre in those times. 


 

 

In his personal life, Chanakya was like an ascetic and the legend goes that he lived in a mud-hut near the royal palace.  A very famous Sanskrit play, "Mudrarakshasa", has for its theme one of the diplomatic feats of Chanakya.

 

 

Two books are attributed to Chanakya:
1. Arthashastra and
2. Chanakya Niti, also known as Chanakya Neeti-shastra.

The Arthashastra discusses monetary and fiscal policies, welfare, international relations, and war strategies in detail. The text also outlines the duties of a ruler.

Chanakya Niti is a collection of aphorisms, said to be selected by Chanakya from the various shastras.


Chanakya is regarded as a great thinker and diplomat in India. Many Indian nationalists regard him as one of the earliest people who envisaged the united India spanning the entire subcontinent.



The diplomatic enclave in New Delhi is named Chanakyapuri in honour of Chanakya. Institutes named after him include Training Ship Chanakya, Chanakya National Law University and Chanakya Institute of Public Leadership. Chanakya circle in Mysore has been named after him.
