She is Human calculator...

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, walked up to the stage. She sat down on a chair smiling at the hundreds of students and professors assembled in the hall. A scholarly professor wrote a 201 digit long number on the black board at her side. The number occupied 10 lines and took four minutes to write. After finishing the number, the professor took out a stopwatch from his pocket and with a nod at the lady he started the timer. There was absolute silence in the hall.

The young lady took one long look at the number and closed her eyes. Seconds ticked by. In deep concentration she appeared to have gone into a trance. At the fifty-second mark, the lady opened her eyes and slowly pronounced the answer, '546372891'. The professor then checked it with the result given by the computer. Yes, she was correct. The number given by her 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 beat the computer.

She was born in Bangalore, and that lady was Shakuntala Devi...........
