About Pi....

Pi was known by the Egyptians, who calculated it to be approximately (4/3)^4 which equals 3.1604. The earliest known reference to pi occurs in a Middle Kingdom papyrus scroll, written around 1650 BC by a scribe named Ahmes. He began the scroll with the words: "The Entrance Into the Knowledge of All Existing Things" and remarked in passing that he composed the scroll "in likeness to writings made of old." Toward the end of the scroll, which is composed of various mathematical problems and their solutions, the area of a circle is found using a rough sort of pi.

Around 200 BC, Archimedes of Syracuse found that pi is somewhere about 3.14 (in fractions; Greeks did not have decimals). Pi (which is a letter in the Greek alphabet) was discovered by a Greek mathematician named Archimedes. Archimedes wrote a book called The Measurement of a Circle. In the book he states that Pi is a number between 3 10/71 and 3 1/7. He figured this out by taking a polygon with 96 sides and inscribing a circle inside the polygon. That was Archemedes' concept of Pi.

New knowledge of Pi then bogged down until the 17th century. Pi was then called the Ludolphian number, after Ludolph van Ceulen, a German mathematician. The first person to use the Greek letter Pi for the number was William Jones, an English mathematician, who coined it in 1706.

In the 1800's people sat down for years on end to find the values of pi to about 1000 places. Imagine doing this by hand with no
calculators. This has become a thing of the past, since the tedium
that used to be done by hand is now done by computer.


Facts About Pi

- Pi is the ratio of the circumference of a circle to the diameter.

- 2 Pi in radians form is 360 degrees. Therefore Pi radians is 180 degrees and 1/2 Pi radians is 90 degrees.

- e raised to the i*pi power equals -1 (e is the base of the natural logarithm and i is the imaginary number which is the sqare root of -1).

- Pi day is celebrated on March 14 at the Exploratorium in San Francisco (March 14 is 3/14). (Bay...you should know... :o )

- All the digits of Pi can never be fully known.

I still dont get its significance though..why is it important to know the ratio of a circle's circumference to its diameter?

since we're discussing about Pi :P ...anyone read 'Life of Pi' by Yann Martel? your thoughts? :roll:

i'd like to read it...soon....:)

Pi is a mysterious constant that had baffled mathematicians for several centuries.

Whenever you draw a perfect circle, the circumference is always 3.14... times that of its diameter. You can test this using your bangle and a piece of thread. If the circumference divided by diameter is not equal to Pi, then it means your bangle is defective - not a perfect circle!

Pi is significant bcoz mathematicians believe its a sign of divine providence and "order among chaos" in materialist things. When the rule of Pi is broken, chaos overtakes order!

"Psi" is another sinister little-known cousin of Pi.

Read The Da Vinci Code for details about Psi.

If you believe in Pi, it means you are religious.
If you believe in Psi, it means you are fundamentalist.

Pi = π
Psi = Ψ

:P

Math Nerds Prepare To Celebrate Pi Day

Pi Day Tuesday honors the infinite numerical challenge whose first three numbers--314--connote March 14.

By W. David Gardner


Mar 13, 2006 12:43 PM

Math aficionados, nerds, and proud math geeks at high tech operations all over the world are preparing to celebrate Pi Day Tuesday to honor the infinite numerical challenge whose first three numbers --314 -- connote March 14.

Although professional and amateur mathematicians venerate Pi, they can take a light-hearted approach to the Pi phenomenon Tuesday.

"Pie-eating contests are very big," said Howard Greenspan, spokesman for MathematiciansPictures.com, a Pi-oriented Web site. "For math nerds and aficionados, it's like Christmas and New Year's all wrapped up into one. There's a lot of activity in high tech operations across-the-board -- major companies, search engines, students, professors."

Greenspan added that the pie-eating contests cover all flavors from apple to strawberry, while bar games often take place in bars and restaurants near high tech centers like Silicon Valley, Boston, and New York.

"There are contests to see who can reel off the biggest number of Pi -- sometimes more than 100 numbers," he added. "It's a popular bar game in some places. Computer guys are totally into these things."

While Pi Day activities have a light-hearted tone to them, Greenspan observed that there are many serious computer scientists who make a life's work out of working with Pi on supercomputers.

In cyberspace, a giant Pi facsimile will drop at exactly 1:59 pm Tuesday. In a nod to the first six digits of Pi, Greenspan said the Pi Drop will be repeated on the site in instant replay for those who miss the actual happening. And, he added there will be an interview with an animated Pi on the Web site.

Noting that Mathematicians Pictures is a business that focuses on "the rock stars of knowledge," Greenspan said the company markets an assortment of novelty items concerning famous scientists and mathematicians. They run the gamut from Ada, the mathematician many believe was the first software programmer, to Archimedes of Syracuse, the brilliant mathematician of ancient Greece.
