Due to popular demand, I have decided to put the page from my old website onto here too..... For those who don't know, I once memorized pi to 2002 decimal places (you can say I was bored). I am even listed on the 1000-Club on Olle the Great's web site. I have now forgotten all but around the first 100 decimal places or so. A Treatise on Pi The number has always been my favourite number because of its unparalleled aesthetic beauty. On this page, I shall provide an overview of this extraordinary number: its history, properties, and its interesting facts. History of Pi Ancient History is perhaps the most famous ratio in mathematics. It is defined as the ratio between the circumference of a circle and its diameter. Throughout the ages, mathematicians have strived to find the value of . One of the earliest reference to was recorded in the Rhind Papyrus during the Egyptian Middle Kingdom, and was written by a scribe named Ahmes around 1650 BC. Ahmes began the scroll with the words: "The Entrance Into the Knowledge of All Existing Things", and made passing remarks that he composed the scroll "in likeness to writings made of old." Towards the end of the scroll, which comprises of various mathematical problems and their solutions, the area of a circle is found using a rough sort of It is interesting to note that the number is also indrectly quoted in the Bible. There is a little-known verse that reads

Music by numbers On this page Some books tying music and mathematics together (reviews in the order I wrote them) Robert Osserman - "Poetry of the Universe" Jamie James - "The Music of the Spheres" Thomas Levenson - "Measure for Measure" I was partly spurred into thinking about this by some nonsense I found about crop circles and "diatonic ratios". Claims that "no-one had ever previously linked mathematics to music" and stuff like that. Jamie James' book is the best to read as an antidote. Osserman is a close second, and Levenson a near miss. "Only gather 2, 3, 4, and 5 together, and the mumbo-jumbo artists of the world will construct a theory, a conspiracy, or a piece of magick." Making scales - Honest, yet ill-fitting work on the numbers Semitone calculator - Converts frequency (and harmonic) ratios to semitones The pentatonic scale - How is it really built? Crop circles - "Diatonic ratios" perhaps, but fairly obviously bogus Robert Osserman "Euler and Bach lived in the eighteenth century and, as was traditional at the time, they worked under the patronage of the nobility or royalty." "Beethoven and Gauss, by contrast, personified the romantic ideals of the early nineteenth century."

45. Sci-Philately - A History Of Science On Stamps tsu Ch ung chi (430501) was a chinese mathematician and astronomer. His approximationof pi was 355/113, which is correct to six decimal places. http://ublib.buffalo.edu/libraries/asl/exhibits/stamps/math1.html

MATHEMATICS AND COMPUTATION I The beginning of mathematics was primitive man's discovery of counting; adding one and one to make two is pictured on this stamp. Upon seeing two birds, an Egyptian makes the cerebral leap to count them on his fingers. ( Detail ) This stamp is the first in a set of ten issued by Nicaragua in 1970 which features important mathematical formulas that changed the face of the earth. Besides showing the law, equation, or formula, the name of its originator, and an application, the reverse of each stamp is printed with a brief paragraph in Spanish explaining the significance of the formula and its far-reaching applications in modern life. Presumably the user can ponder this educational message while licking the stamp; whether the recipient would appreciate it or be aware of it is another matter. The illustrations contain a wealth of interesting detail, and the sci-philatelic sleuth can enjoy identifying the many clues and their relationship to the original formula. A well-known theorem in geometry is named after Pythagoras, who flourished in the 6th century BC, and was a teacher in Samos, Babylon, and Egypt: the sum of the squares of the sides of a right triangle equals the square of the hypotenuse. Actually, the so-called Pythagorean triples were known already in Babylonian times. The striking design of the Greek stamp is a visual representation of the theorem. (

A competition to find the best approximations for pi W I N I O N O W PI Competition The Contest Center 59 DeGarmo Hills Road Wappingers Falls, NY 12590 W I N I O N O W Like this site? Please tell a friend Please sign our Guestbook This is an open-ended competition to find the best possible approximations to pi (about 3.14159 26535 89793 23846 26433). A good approximation would be an expression which matches pi to more significant digits than the number of digits contained in that expression. For example, the most common approximation to pi is 22/7 which is about 3.14286. This contains 3 digits, and matches the first 3 digits of pi, so it is a fair approximation. We will consider 4 types of approximations. The first type uses only the mathematical operations of addition, subtraction, multiplication, division, and square root. It may not use other operations such as decimal fractions, exponentiation, logarithms, or any trig functions. For example, 355/113 (approximately pi+0.00000 0266) would be a valid expression, but 2 arcsin(1) would not. These approximations can be constructed with ruler and compass. The second type adds exponentiation and higher roots to the list of allowed operators. For example 7

48. Yet Another Story Of Pi About 150 AD, Ptolemy of Alexandria (Egypt) gave its value as 377/120 and inabout 500 AD the chinese tsu Ch ungchi gave the value as 355/113. http://www.geocities.com/CapeCanaveral/Lab/3550/pi.htm

The story of pi by Lazarus Mudehwe Undoubtedly, pi is one of the most famous and most remarkable numbers you have ever met. The number, which is the ratio of circumference of a circle to its diameter, has a long story about its value. Even nowadays supercomputers are used to try and find its decimal expansion to as many places as possible. For pi is one of those numbers that cannot be evaluated exactly as a decimal - it is in that class of numbers called irrationals. The hunt for pi began in Egypt and in Babylon about two thousand years before Christ. The Egyptians obtained the value (4/3)^4 and the Babylonians the value 3 1/8 for pi. About the same time, the Indians used the square root of 10 for pi. These approximations to pi had an error only as from the second decimal place. (4/3)^4 = 3,160493827... 3 1/8 = 3.125 root 10 = 3,16227766... pi = 3,1415926535... The next indication of the value of pi occurs in the Bible. It is found in 1 Kings chapter 7 verse 23, where using the Authorised Version, it is written "... and he made a molten sea, ten cubits from one brim to the other : it was round about ... and a line of thirty cubits did compass it round about." Thus their value of pi was approximately 3. Even though this is not as accurate as values obtained by the Egyptians, Babylonians and Indians, it was good enough for measurements needed at that time. Jewish rabbinical tradition asserts that there is a much more accurate approximation for pi hidden in the original Hebrew text of the said verse and 2 Chronicles 4:2. In English, the word 'round' is used in both verses. But in the original Hebrew, the words meaning 'round' are different. Now, in Hebrew, etters of the alphabet represent numbers. Thus the two words represent two numbers. And - wait for this - the ratio of the two numbers represents a very accurate continued fraction representation of pi! Question is, is that a coincidence or ...
