How did he prove it? If he were to recite it at one digit per second, it would take a little over a day.

And that was from memory.
Back in school, we had this thing called Pie Day. It was on March 14. In numerical terms thats 3.14 or pi. Anyway, whoever could list the most pi digits won a... yep you guessed it, a pie. I won it in eighth grade, and the pie was great. I don't remember any of the numbers now so I can't contribute. Sorry.
I can't remember anything...
i only know 3.14... that's it. LOL!
Well I'm studying engineering , so thank god we let the scientists bother with the numbers after the decimal. 3 is sufficiently close for pi :)

This would be difficult... Not cheating would require you to calculate each consecutive digit of pi in your head (or, at most on a piece of paper). Probably by using some Taylor series, that you derived from first principles (looking up the series would also be cheating).
Unless you memorised pi before the question was stated.
Penalty for cheating: Six lashes with a straw over the bridge of the nose.
Detecting it: Ask Big Brother
I once memorized all the digits of pi. It was easy.

Yes,the Greek symbol pi..Nice article.A number with huge role at mathematics.Ancient Greeks had found many things about maths.The Guinness-recognized record for remembered digits of π is 67,890 digits, held by Lu Chao, a 24-year-old graduate student from China. It took him 24 hours and 4 minutes to recite to the 67,890th decimal place of π without an error.But very soon i will write you to see an impressive video from Youtube about pi..

pi is irrational. you can't memorize all the digits because they never repeat and they never terminate

The first 100 digits of pi are sufficient to calculate within the size of a proton the circumference from the radius of any circle that fits in our universe.
Not necessarily. Firstly we don't know how big the universe is. Secondly this will depend on the true geometry of the universe. Since there is mass in the universe the geometry is not Euclidean.

I used to know it to 60 d.p. Now it has fallen to 32, but I manage to get by.

Wow, convicts have no sense of humor.

This is only a theory. Next month, someone could show Einstein to be misguided, and show that Euclidean geometry makes a lot more sense.

I am sorry to say that but Euclidean geometry it's not stands because at nature all these perfect geometry shapes simply does not exist.We don't have perfect circles for example.Chaos theory explanes better nature and fractal geometry is more specific and realistic(and weird also,a geometry that says a dimension of a thing is 2,4 or 1,6!!).But Euclidean geometry is a simple and easy tool to understand many basic things about his geometry shapes.
?
Euclidean geometry explains much more than perfect geometrical shapes. There are some aspects of this system that are generally regarded as flawed nowadays. However, the reason Euclidean geometry is not accepted is not because perfect circles don't exist. It is because we have been presented with better explanations; namely, the theory of general relativity.

I mean this thread is for posting digits of pi, but it's obviously not a big performance when someone just uses a calculator (which will soon be insufficient) or a site that has the first billion digits of pi. It's about repeating the digits of pi without looking at the answers, is it not?
And I'm not saying one should be punished for cheating on this. It's just... what's the point of such a thread if everyone just uses the internet to find the digits of pi and just copies them here?
But how about the number 10/9. Let me start with the first few digits: 1.111111... Who else knows more digits?
