update:\nI found the university that MOOCOW was referring to:\nhttp://pi2.cc.u-tokyo.ac.jp/pi_current.html\n\nExcept that as of this past December 2002, their new record was over 1 TRILLION.\nIf you care to download the document, they say it is available on their FTP server\nftp://pi.super-computing.org/\n\nre: not needing the number posted on this site > That's good because the posted number I found took up more than 1,800 pages in my word document with 1/2" margins.\nThe longest PI I was able to find was 5,001,002 characters on this site;\n\nhttp://www.hepl.phys.nagoya-u.ac.jp/docs/pif500.text.gz

No, it's an infinite decimal sequence (as far as we know) so far Pi has over 400,000,000 digits, you can see them over on this page, http://www.hepl.phys.nagoya-u.ac.jp/docs/pif500.text.gz

everything has a sqare root , archimedes was said to be the first to discover the square root to everything by using the simplest mathmaticial soloution even used today wihch goes 1,2,3,5,8,13,21 and on and on and on forever just like the universe and i am no "string theorist" either ... as for symmetry well thats another story.... pie is what im sure you know as 3.14 and is used to measure any size of circles and is used to proove that the universe is infinate because pie is infinate, take a look at this cut and paste and then veiw the proof on the link i have provided about it.... o.k here it is... \n\nFrom the definition, π can be found by taking a circle (any circle at all) and dividing the length of its circumference3 by the length of its diameter4. This will give you a value close to the number stated below, depending on how accurate your measurements are.\n\nWhat Exactly is the Value of π?\n\nπ, to 2,000 decimal places, is:\n\n3.1415926535897932384626433832795028841971693993751058209749445\n923078164062862089986280348253421170679821480865132823066470938\n446095505822317253594081284811174502841027019385211055596446229\n489549303819644288109756659334461284756482337867831652712019091\n456485669234603486104543266482133936072602491412737245870066063\n155881748815209209628292540917153643678925903600113305305488204\n665213841469519415116094330572703657595919530921861173819326117\n931051185480744623799627495673518857527248912279381830119491298\n336733624406566430860213949463952247371907021798609437027705392\n171762931767523846748184676694051320005681271452635608277857713\n427577896091736371787214684409012249534301465495853710507922796\n892589235420199561121290219608640344181598136297747713099605187\n072113499999983729780499510597317328160963185950244594553469083\n026425223082533446850352619311881710100031378387528865875332083\n814206171776691473035982534904287554687311595628638823537875937\n519577818577805321712268066130019278766111959092164201989380952\n572010654858632788659361533818279682303019520353018529689957736\n225994138912497217752834791315155748572424541506959508295331168\n617278558890750983817546374649393192550604009277016711390098488\n240128583616035637076601047101819429555961989467678374494482553\n797747268471040475346462080466842590694912933136770289891521047\n521620569660240580381501935112533824300355876402474964732639141\n992726042699227967823547816360093417216412199245863150302861829\n745557067498385054945885869269956909272107975093029553211653449\n872027559602364806654991198818347977535663698074265425278625518\n184175746728909777727938000816470600161452491921732172147723501\n414419735685481613611573525521334757418494684385233239073941433\n345477624168625189835694855620992192221842725502542568876717904\n946016534668049886272327917860857843838279679766814541009538837\n863609506800642251252051173929848960841284886269456042419652850\n222106611863067442786220391949450471237137869609563643719172874\n677646575739624138908658326459958133904780275901\nOf course, that's not where it ends. π continues for an infinite number of decimal places, and there is no pattern to the order of the digits. Any pattern that you may think is emerging is just an illusion, and will quickly disappear to be replaced by another 'pattern'. For ease of mathematical calculations, π is usually reduced to 3.142, or 3.14159 for a more accurate result.

Don't use 3.142.Use 22/7 as the value of Pi.Its "pi" not "pie".Pi=3.142 (approx.).In reality it goes into hundreds of decimal points without terminating.However "pi" is also equal to the fraction 22/7.If you have trouble with the decimals substitute the fraction as the value of pi-it is acceptable.This way it will be easier for you to calculate sums without a calculator.Pi is basically just the constant ratio that exists between the circumference and radius of any circle.C/R=22/7.

Pi's digits have many interesting properties, although not very much is known about their analytic properties. Spigot (Rabinowitz and Wagon 1995; Arndt and Haenel 2001; Borwein and Bailey 2003, pp. 140-141) and digit-extraction algorithms (the BBP formula) are known for pi.\nPi's continued fraction is given by [3, 7, 15, 1, 292, 1, 1, 1, ...] (Sloane's A001203). Its Engel expansion is 1, 1, 1, 8, 8, 17, 19, 300, 1991, 2492, ... (Sloane's A006784). \n\n Pi is known to be irrational (Lambert 1761; Legendre 1794; Hermite 1873; Nagell 1951; Niven 1956; Struik 1969; Königsberger 1990; Schröder 1993; Stevens 1999; Borwein and Bailey 2003, pp. 139-140). In 1794, Legendre  also proved that  is irrational (Wells 1986, p. 76). Pi is also transcendental (Lindemann 1882). An immediate consequence of Lindemann's proof of the transcendence of  pi also proved that the geometric problem of antiquity known as circle squaring is impossible. A simplified, but still difficult, version of Lindemann's proof is given by Klein (1955). \nIt is also known that  pi is not a Liouville number (Mahler 1953), but it is not known if  pi is normal to any base (Stoneham 1970). It is not known if pi+e, pi/e or  natural log of pi are irrational. However, it is known that they cannot satisfy any polynomial equation of degree  less than or equal to 8 with integer coefficients of average size 10 raised to the power 9. Pi crops up in all sorts of unexpected places in mathematics besides circles and spheres. For example, it occurs in the normalization of the normal distribution, in the distribution of primes, in the construction of numbers which are very close to integers (the Ramanujan constant), and in the probability that a pin dropped on a set of parallel lines intersects a line (Buffon's needle problem). Pi also appears as the average ratio of the actual length and the direct distance between source and mouth in a meandering river (Stølum 1996, Singh 1997). \n\nA brief history of notation for pi is given by Castellanos (1988).Pi is sometimes known as Ludolph's constant after Ludolph van Ceulen (1539-1610), a Dutch  calculator. The symbol  was first used by Welsh mathematician William Jones  in 1706, and subsequently adopted by Euler . In Measurement of a Circle, Archimedes  (ca. 225 BC ) obtained the first rigorous approximation by inscribing and circumscribing  6* 2^n-gons on a circle using the Archimedes algorithm. Using  n=4 (a 96-gon), Archimedes  obtained that 3+ 10/71 < pi < 3+ 1/7......(Wells 1986, p. 49; Shanks 1993, p. 140; Borwein et al. 2004, pp. 1-3). \n\nThe Bible contains two references (I Kings 7:23 and Chronicles 4:2) which give a value of 3 for  pi (Wells 1986, p. 48). It should be mentioned, however, that both instances refer to a value obtained from physical measurements and, as such, are probably well within the bounds of experimental uncertainty. I Kings 7:23 states, "Also he made a molten sea of ten cubits from brim to brim, round in compass, and fiv

not sure--The first one million digits of π and 1/π are available from Project Gutenberg (see external links below). The current record (December 2002) by Yasumasa Kanada of Tokyo University stands at 1,241,100,000,000 digits, which were computed in September 2002 on a 64-node Hitachi supercomputer with 1 terabyte of main memory, which carries out 2 trillion operations per second, nearly twice as many as the computer used for the previous record (206 billion digits). http://en.wikipedia.org/wiki/Pi still not sure-2002 was 4 years ago there maybe a larger number. http://directory.google.com/Top/Science/Math/Recreations/Specific_Numbers/Pi/Digits/

Pi is the ratio of a circle's circumference to its diameter (it's the same for every circle). It's an irrational number, which means that it repeats infinitely, and so far no one has been able to find a pattern in the digits. It's also a transcendental number, which means that it is not possible to construct a polynomial function f with integer coefficients such that f(pi) = 0.\n\nBecause of all that, it's not possible to come up with all the digits of pi, at least not unless someone finds a pattern to them. The world record for most digits of pi calculated is 1,241,100,000,000, which is held by Yasumasa Kanada (or, more accurately, by his computer).\n\nThe formula that Kanada used to calculate pi is large, and kind of cumbersome for anyone but a computer to use. It is, however, very efficient, which is why he used it.\n\nThe simplest formula for calculating pi is to use the arctan series. We know that arctan (pi/4) = 1, by definition of arctan. Using the Taylor Series expansion, we find\n\narctan (t) = t - t^3/3 + t^5/5  - t^7/7 + t^9/9 - ...\n\nThat series does go on forever, but so does pi, and so you can use it to calculate pi/4, by putting in 1 for x:\n\narctan (1) = 1 - 1/3 + 1/5 - 1/7 + 1/9...\n\nThis will give you an approximation of one fourth of pi. With those first five terms, we get about 0.83492 for pi/4, which gives the value of pi as about 3.33968. The real first 6 digits of pi are 3.14159, so you can see that this method needs a lot of terms to be accurate. But it is both conceptually easy and simple to remember.\n\nIf you want to learn more, try http://www.escape.com/~paulg53/math/pi/index.html , which has some other methods for how to calculate pi. The wikipedia article on pi (http://en.wikipedia.org/wiki/Pi ) also has other formulae, including some very modern ones.
