Eve Andersson (eve@eveandersson.com) Comments Pi page Just to say it's wonderful to find the Pi Page still going - as a young(ish) graduate in the early 1990s, the site probably did more than anything else to convince me that Mosaic (ask your grandparents) was useful for something other than downloading porn and spreading maliciously doctored photos worldwide. If there's ever an Internet Lifetime Achievement Award, I'll happily nominate Eve... And another thing - how come nowhere on this page can I find my favourite property of pi, our old friend e^(i*pi)-1? And another thing (part 2) - I just want to point out that I got 13/25 on the Pi Test - and am a qualified mathematician (who admittedly graduated 13 years ago but even so!) And (one last) thing - if the page needs a pompous slogan it should really be "One measures a circle beginning anywhere" (motto of the Fortean Society and all its spin-offs) - it may be meaningless but it sounds very impressive. Which in itself kinda sums up most mathematics. Aidan Merritt Updates Your Pi memorization and calculation records aren't up to date. I knew which records you were talking about, but I think that you should add the fact that 1.2411 trillion digits of pi have been calculated and that the Japanese guy has now memorized 60,000. Other than this you're site is great and I love the trivia game, thx.

The Topic: Pi Easier - Pi sounds like pie and is equal to about 3.1416. In math, this is the ratio of the circumference of a circle to its diameter. In other words, pi is a number that equals the quotient of the circumference of a circle divided by its diameter. Many people celebrate pi by holding a Pi Day on March 14th or 3/14. Harder - The Greek letter pi represents the number by which the diameter of a circle must be multiplied to obtain the circumference. Pi is an irrational number. That is, it cannot be written as a simple fraction or as an exact decimal with a finite number of decimal places. However, you can increase the number of digits until you reach a number as near to pi as needed. Mathematicians with computers have calculated pi to millions of decimal places. Pi is used in several mathematical calculations. The circumference of a circle can be found by multiplying the diameter by pi (c = pi X d). The area of a circle is yielded by multiplying pi by the radius squared (A = pi X r-squared). Pi is also used to calculate the area of a circle, and the volume of sphere or a cone.

...and continuing updates Why "The story of pi reflects the most seminal, the most serious and sometimes the silliest aspects of mathematics. A surprising amount of the most important mathematics and a significant number of the most important mathematicians have contributed to its unfolding directly or otherwise. Pi is one of the few concepts in mathematics whose mention evokes a response of recognition and interest in those not concerned professionally with the subject. It has been a part of human culture and the educated imagination for more than twenty five hundred years. The computation of Pi is virtually the only topic from the most ancient stratum of mathematics that is still of serious interest to modern mathematical research. And to pursue this topic as it developed throughout the millennia is to follow a thread through the history of mathematics that winds through geometry, analysis and special functions, numerical analysis, algebra and number theory. It offers a subject which provides mathematicians with examples of many current mathematical techniques as well as a palpable sense of their historical development." The above passage is taken from the introduction to "Pi : A Source Book" by L. Berggren, J. Borwein and P. Borwein. It is a large collection of papers on pi and will appear with Springer-Verlag sometime in 1997. Much additional material is available in the 1986 Wiley volume

29. The Amazing History Of Pi That the ratio of the circumference to the diameter of a circle is constant (namely, pi) has been recognized for as long as we have written records. http://ualr.edu/lasmoller/pi.html

Did you know . . .? has a long and interesting history! Ancient history More pi history A novel way to compute pi- The symbol for pi ... For more information That the ratio of the circumference to the diameter of a circle is constant (namely, pi) has been recognized for as long as we have written records. A ratio of 3:1 appears in the following biblical verse: And he made a molten sea, ten cubits from the one brim to the other: it was round all about, and his height was five cubits: and a line of thirty cubits did compass it about. (I Kings 7, 23; II Chronicles 4, 2.) The ancient Babylonians generally calculated the area of a circle by taking 3 times the square of its radius ( =3), but one Old Babylonian tablet (from ca. 1900-1680 BCE) indicates a value of 3.125 for pi. Ancient Egyptians calculated the area of a circle by the following formula (where d is the diameter of the circle): This yields an approximate value of 3.1605 for pi. Beginning with a hexagon, he worked all the way up to a ploygon with 96 sides! Archimedes's method for approximating the value of pi.

Peter Alfeld, Department of Mathematics, College of Science University of Utah Archimedes and the Computation of Pi Archimedes (approximately 285-212 B.C.) was the most famous ancient Greek mathematician and inventor. He invented the Screw of Archimedes , a device to lift water, and played a major role in the defense of Syracuse against a Roman Siege, inventing many war machines that were so effective that they long delayed the final sacking of the city. For a concise and yet informative discussion of Archimedes see the article "Archimedes" in the macropedia of the Encyclopedia Britannica. Here are some links to other Archimedes related web pages: Eratosthenes of Cyrene was a contemporary of Archimedes (Eratosthenes was about ten years younger), and the two corresponded on various matters.

34. Pi If pi were just 3, then we wouldn t have circles in threedimensional space as we know them. In a black hole, a point in space so dense that even light http://www.geocities.com/lady_lizzie/info.html

What is Pi? Welcome to the world of mathematics. Believe it or not, you have been living in a world synchronized by numbers for your entire life. Everything has a shape, and in order to get to that shape, numbers are needed. You might say that anything round is "pied" because in order to get the area of it, you need that special ratio. If pi were just 3, then we wouldn't have circles in three-dimensional space as we know them. In a black hole, a point in space so dense that even light deflects towards it and cannot escape, the ratio of circumference to diameter is closer to 4. We might have something like Edwin Abbott's Flatland if pi were less than its current value. A Brief History The first famous "pi people" in history were probably the very first people on the planet. They saw circles everywhere: in other people's eyes, the Moon, the Sun, etc. In order for these people to make the first step in determining pi, however, they had to understand the concept of magnitude. For example, the bigger a stone is, the heavier it is. The smaller the stone, the lighter it is. From these simple observations, prohuman then had to realize that some things have direct proportional relationships. He had to look at a circle and think, "The wider a circle is 'across', the longer it is 'around.'" From this, a very profound statement would be, "No matter how long or wide a circle is, the relationship between them is always the same." The first cultures given credit for finding a value of pi are the Babylonians and the Egyptians. In the year 2000 B.C.E., the Babylonians determined that pi is equal to 3 1/8 and the Egyptians arrived at 4(8/9). Both got these values, probably, by drawing a circle in the sand and measuring the distance around it with a rope. That point on the rope is then marked and then the distance across it is measured. To determine pi, the person would have to see that the circumference is about three times the length of the diameter, with a little bit left over. Obviously, it's impossible to tell just by looking that the little bit is really approximately .1415926535897932384626433832795028841971693993751058209749445923078164062862099, so the 1/8 (.125) that the Babylonians came up with is not very far off for that time period.
