A high school student Tuesday recited 8,784 digits of Pi — the non-repeating and non-terminating decimal — likely placing him among the top Pi-reciters in the world.

He was hoping to get 10,790 digits.

I'm lucky if I can remember 4 digits. [Razz]

I found the last digit of pi the other day. It's not as long as everyone thinks.

(For those of you who are interested, the last digit is a 9).

That beats the crap out of my friend who thought he was pretty BA because he could recite 40 digits of pi.

I am so emailing him that link right now... [Razz]

Meh. I'm lucky if I can remember where the Pi key is on my scientific calculator...

and I'm doing even better if I can remember where I put said scientific calculator... [Big Grin]

Snaggy____________Years ago when I was a math pup there was a book of math tables and standards I believe it was published by the Chemical Rubber company, In their disclaimer at the front they had Pi to one hundred and ten places quite good for 1962, however the next line was the best, these tables are proofed against many sources and notice of any errors will be appreciated.

Sometimes I wonder if this is what the general public thinks that mathematicians do. While impressive, this is not a "mathematical accomplishment", as the article states.

Metasquares________________I wonder how many people know that Pi is the area of the incribed circle of unit one radius, as compared to the area of the two unit square. Who needs that level of accuracy, they hit the moon with 3 digits and mid course corrections.

Jenny what is that number?
You've gotta' keep it in mind.
Jenny write down this number:
three point one four one five nine
(three point one four one five nine)

Thank you, thank you very much.

3.1415926535897 ... dang, I can never remember the next one. I think it's either 4, or it rounds to 4, though.

I'm told the "thing to do" for incoming freshmen at Caltech is to memorize as many digits of pi as possible in an attempt to impress the current students. They're *weird* over their, eh? [Razz]

extended digits of pi are useless from an engineering standpoint. pi out to 40 digits describes the ratio of a circle of radius 13.7 billion ly (the universe-circle) accurate to an hydrogen atomic diameter. (ish)

[ohwell] I think that although for a human being is pretty hard to remember that length of digits, I'd leave this job to a computer... but this is
still quite amusing after all.

PS: I didn't knew there was a difference in pronunciation between π and pie. [Razz]

PPS: As far as my calculator knows, I know...

THANK YOU! [thumbsup] [Big Grin]

Yes I have to scream it. I find this whole "let's find as many digits of Pi we can" stuff stupid. I heard they finds digits with some kind of algorithm, but what if the algorithm is flawed comparatively to the definition of Pi? To me, Pi is the ratio between the circumference of a circle and its radius. So has someone drawn/taken a perfect circle, measured its circumference an radius, taken into consideration the uncertainty of the measuring tool, did the division, and confirmed every new digit found? (Or am I just ignorant of the certainity level of the algorithm used?)

Back when I was in school, my book of mathematical tables (now that's showing my age, have todays school kids even seen a book of maths tables?) had 2 pages of 'random digits', which began
14 15 92 65 35.....

Look familiar?

Digits of pi are a high-quality source of 'random' numbers.

Pi is the integral of the curve x^2 + y^2 = 1

It was actually one of the first integrals ever calculated, Archimedes used 2 96-sided polygons to calculate 223/71 < pi < 22/7, long before the 'invention' of calculus.

Funny how a few of the posts looked familiar....

Then, I saw one post and thought "Hmm...that's awfully pedantic - who wrote that?"
(But not nearly as pedantic as some awesome posts there. [Smile] )
I looked up and to the left and realized "Oh, that was me!" [Razz] Finally, I spotted the dates on the posts...

I know the distance from New York City to the Sea of Tranquility on the Moon to the nearest 1/10,000th of an inch.

It is exact, precise and irrefutable.

But then, who wants that information?

What is the purpose of human life?

Is anyone out there?

I don't know what I was thinking... it seemed like a good idea at the time.
