Fredrik Posted December 7, 2002 Pi is very interesting. The last few days I've come up with a couple of approximations, for example: 1977646078/629504298 8769956796^(1/20) 789578687047901181^(1/36) and 68342776146017258398967520978^(1/58) I also have a file with 50,000,000 digits of Pi which I calculated with PiFast in some 15 minutes. 0 Share this post Link to post
Fletcher` Posted December 7, 2002 I'm sorry, but who exactly needs a number that precise? 0 Share this post Link to post

Grazza Posted December 7, 2002 For practical purposes, 355/113 is quite good, and easy to remember. The next fraction that is more accurate involves, IIRC, two five-digit numbers. DooMBoy: before you ask, I remember that from a boring textbook on number theory I skimmed through when I was a maths undergraduate. I decided to skip that course. :) 0 Share this post Link to post
Remilia Scarlet Posted December 7, 2002 I memorized it this far: 3.1415926535829. Don't ask how, as I'm not sure. To get it, don't you just take some measurements off a real, true circle, and devide? Or is this wishful thinking? 0 Share this post Link to post

DOOM Anomaly Posted December 7, 2002 "The Joy of Pi" Well, what a uncanny term as I see it. "It's been a fellow traveler in mathematical history," said Peter Borwein, a mathematics professor at Simon Fraser University in Burnaby, British Columbia, who once held the record for calculating pi to about 2 billion decimal places. "It isn't so much, 'Does anyone really care what the 1.24 trillionth decimal place is?' -- probably not -- but the stuff that's been discovered in the process."...And I thought I needed a life... 0 Share this post Link to post

Grazza Posted December 7, 2002 Fredrik said:68342776146017258398967520978^(1/58) ... etc.Fredrik, if you're going to waste your time on stuff like this, at least devote it to a useful number, such as koppa: 2 x (sum for r even and positive of r^-r) = koppa = integral from 0 to 1 of (x^-x) - (x^x) wrt x [I wish the forum software had an equation editor.] It starts off 0.507855... And yes, the fact that the two quantities are equal has been proven analytically. I'm not sure whether the integral or the sum will provide a quicker method for evaluating it to many decimal places. If you find a use for koppa, give me some credit, OK? 0 Share this post Link to post

IMJack Posted December 8, 2002 Y'know, I bought this calculator (scientific, double display) at the beginning of the semester. It has like a dozen physical constants accessbile from a function key, crap that would have been really useful to me for my Physics class (stuff like Avagrado's number, or the charge of an electron, or the mass of elementary particles). And yet I idn't realize that thing was there until the fourth midterm exam. Go figure. Anyway, back on topic. 0 Share this post Link to post

Ichor Posted December 8, 2002 The fun thing about pi is that you could make up any digits you want for its decimal places (for instance, the 461 millionth place is a 6), and all but the biggest geeks on the planet will never know the difference. 0 Share this post Link to post

Wobbo Posted December 8, 2002 Fredrik said:Here is a very interesting page. Thats the most insane thing ive seen ever since the alternate quadratic fomula almost destroyed my brain. I know a guy whos memorized the thing up to 250 places. Theres really no point unless they figure out a pattern, unfortunateley theres very little that can be done about finding patterns no matter how much raw power you put into it 0 Share this post Link to post
