Shakuntala Devi : Human Computer
January 24, 1977. A cold and windy Monday afternoon at Southern Methodist University in Dallas, Texas. A beautiful young lady smartly clad in a sari, walks up to the stage. She sits down on a chair smiling at the hundreds of students and professors assembled in the hall. A scholarly professor writes a 201 digit long number on the black board at her side. The number occupies 10 lines and takes four minutes to write. After finishing the number, the professor takes out a stopwatch from his pocket and with a nod at the lady he starts the timer. There is absolute silence in the hall.
The young lady takes one long look at the number and closes her eyes. Seconds tick by. In deep concentration she appears to have gone into a trance. At the fifty-second mark, the lady opens her eyes and slowly pronounces the answer, ?546372891?. The professor checks it with the result given by the computer. Yes, she is correct. It is the 23rd root of the 201 digit long number. Earlier that day, the fastest computer of the time, Univac 1108, had taken 62 seconds to give the answer. Every member of the audience jumped to their feet and applauded the genius who has beaten the computer.In Dallas she competed with a computer to see who give the cube root of 188138517 faster, she won.
In 1977 At university of USA she was asked to give mentally the 23rd root of 91674867692003915809866092758538016248310668014430862240712651642793465704086709659 32792057674808067900227830163549248523803357453169351119035965775473400756818688305 620821016129132845564895780158806771 (201-digit number).
She answered in 50seconds. The answer is 546372891. It took a UNIVAC 1108 computer, full one minute and 2 seconds (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.
Her correct answer was 18,947,668,177,995,426,462,773,730. This event is mentioned on page 26 of the 1995 Guinness Book of Records.
