Daniel Tammet did this.
he is from Britain and has a rare combination of asbergers and synthesia. he says that when does calculations and long memorization that he is not consciensly doing it, that instead he sees an pictographic representation of the quantity.
Tammet recited only 22, 514 digits.
Hiroyuki Goto from Japan in 1995 was the first to do 42195 digits . This number has since been surpassed.
There are too many digits, but I'll give you the ones I've memorized: 3.141592653589793238462643383279502884197169399375105820974944... ~ To the above answer: That's not what the question is asking. Answer: Digits of pi used to be calculated by dividing the circumference by the diameter of a circle. The same answer will come out for all circles. Now, we have machines that can crunch up millions of digits in a relatively short amount of time.
Because Pi is known to be an irrational number it means that the digits never end or repeat in any known way. But calculating the digits of Pi has proven to be an fascination for mathematicians throughout history. Some spent their lives calculating the digits of Pi, but until computers, less than 1,000 digits had been calculated. In 1949, a computer calculated 2,000 digits and the race was on. Millions of digits have been calculated, with the record held (as of September 1999) by a supercomputer at the University of Tokyo that calculated 206,158,430,000 digits. (first 1,000 digits). However, learning 3.141, is all that is necessary. But you can go on and on, to infinity, and never find the exact circumference of a circle. I have only memorized 205 digits of pi; and yes I do use it to find the circumference of a circle.
1.2411 trillion digits (1,241,100,000,000) digits of pi have been dicovered.
3.14159265358979323864062384626238832795028841971693939937510582097494459230781640628620898628034825342117067 These are the hundred digits of pi
The first 55 digits of pi after the decimal point are: 3.1415926535897932384626433832795028841971693993751058209
Hiroyuki Goto memorized 42195 digits of pi on 2-18-95 where... i dont know in his office ? at his house ?
Goto, Hiroyuki
Bobby Joe the second
Hiroyuki Goto Hiroyuki Goto
it was a Japanese man named Hiroyuki Goto.
Janae Hewlett from Richmond Illinois. Hiroyuki Goto is the one who is recognized for this feat.
The man was Chuck Norris. Don't ask where he is from, or he will find you.
42195
Hiroyuki Goto from Japan did that on February 18,1995 according to the related link. Since then, Lu Chao from China and Krishan Chahal have recited 678.90 and 43000 digits respectively.
A Japanese psychiatrist memorized 83,431 digits of pi. This man is Akira Haraguchi.
It was Hiroyuki Goto, of Japan. He set the world record which remained unbroken until 2005. The current record (as at April 2018) is held by Suresh Kumar Sharma of India who, on 21 October 2015 recited pi to 70030 digits.
