India! The country with amazing diversity and wonders has many champions. All these are real facts and real records. Most of them are certified by authentic record books like Guiness Book of Records & Limca Book of Records. I am trying to tabulate as many as I can. Please help me in my efforts by adding more facts and records.

MEMORISING MOST PLACES OF e


The mathematical constant e is one of the most important numbers in mathematics, along with the constant π(pi), and the imaginary unit i. The mathematical constant e is the unique real number such that the function e to the power of x has the same value as the slope of the tangent line, for all values of x. The number e is sometimes called Euler's number after the Swiss mathematician Leonhard Euler.

Since e is transcendental, and therefore irrational, its value cannot be given exactly as a finite or eventually repeating decimal. The numerical value of e truncated to 20 decimal places is:

2.71828 18284 59045 23536...

Bhaskar Karmakar of India created world record by reciting e to an astonishing 5,002 decimal places. He performed his world record breaking feat on 25 November 2007, taking a time of just 1 hour 29 minutes 52 seconds. He also recited the value backwards to 5002 decimal places in 1 hr 48 min 45 seconds.
