	Pi - Wikipedia, the free encyclopedia (Site not responding. Last check: 2007-11-06)
		In Euclidean plane geometry, π may be defined either as the ratio of a circle's circumference to its diameter, or as the ratio of a circle's area to the area of a square whose side is the radius.
		Pi is also known as Archimedes' constant (not to be confused with Archimedes' number) and Ludolph's number.
		There is an entire field of humorous yet serious study that involves the use of mnemonic techniques to remember the digits of π, which is known as piphilology.

	Buffon's needle - Wikipedia, the free encyclopedia
		Using integral geometry, the problem can be solved to get a Monte Carlo method to approximate π.
		Mario Lazzarini, an Italian mathematician, performed the Buffon's needle experiment in 1901.
		Tossing a needle 3408 times, he attained the well-known estimate 355/113 for π, which is a very accurate value, differing from π by no more than 3×10

	PI (Site not responding. Last check: 2007-11-06)
		Pi is a name given to the ratio of the circumference of a circle to the diameter.
		In 1761 Lambert proved that Pi was irrational, that is, that it can't be written as a ratio of integer numbers.
		Because Pi is known to be an irrational number it means that the digits never end or repeat in any known way.

		Pi is an irrational number: that is, it cannot be written as the ratio of two integers.
		While the original Greek letter for pi was phonetically equivalent to the English letter p, it has now evolved to be pronounced like the word pie in most circles.

	Station Information - Pi through experiment
		The number Pi (π) can be found through experiment by drawing parallel lines a constant distance apart and then randomly dropping matches half that length.
		So if you change the probability to radians by multiplying by half pi and the perpendicualar distance / 2 to sin x by multyplying by 2 you find that the area under a sine graph which uses radians is 1.
		Area under sinegraph until half pi under a sine graph is the same as that in a cosine graph as same as working back form half pi radians for sine.

	Pi and its approximations (Site not responding. Last check: 2007-11-06)
		Pi is an irrational number, but it must be noted that this was not actually proved until Lambert came along in 1761.
		This means that pi is a number that will go on forever and ever, and so no matter how good a degree of accuracy you come up with it will always only be an approximate.
		As pi has been sought after for over 3500 years and many brilliant minds have been confronting the problem of pi, you would have thought that it has always been progress.

	Pi through the ages
		The transcendentality of pi means that there is no ruler and compass construction to construct a square equal in area to a given circle.
		It is almost unbelievable that a definition of pi was used, at least as an excuse, for a racial attack on the eminent mathematician Edmund Landau in 1934.
		Landau had defined pi in this textbook published in Göttingen in that year by the, now fairly usual, method of saying that pi/2 is the value of x between 1 and 2 for which cos x vanishes.

		While Pi is comprised of an infinite number of decimal digits, I have seen no proof that these digits do not repeat.
		If that is the case, then Pi might still encapsulate the sum of all human knowledge, since the sum of all human knowledge is certainly finite.

		They are also interested in the Guinness Book of World Records and the places that pi has been divided out to and the number of places that pi has been memorized to - I just want to tell then how to find this.
		Pi doesn't have this property, and in fact, it's not even a predictable sequence like.10110011100011110000..., which, though not rational, is very easily characterized.
		Evaluation of pi has an extremely interesting history; the Egyptians and Greeks had decent approximations to it (I believe 22/7 and 3.2), which were actually better than the one used by medieval Europeans, 3.

	The Validity of Pi
		Equipment: Needed for this experiment is one circle, one cylindrical object capable of having it's volume measured, a measuring tape, pen, paper, and a calculator is optional.
		The formula given for the circumfrance of a circle is given by C = 2(pi)r, By dividing the measured circumfrance by twice the value of the radius, the value of Pi should be determined.
		Conclusion: Based on the percent error of roughly 3-4% it is safe to say that Pi is an adequate approximation in dealing with circles, and furthermore, it would be tough to argue against all of science that the value of Pi is wrong based on it being only 3% off.
