Interesting Facts about Pi.**

1. Pi is the most recognized mathematical constant in the world. Scholars often consider Pi the most important and intriguing number in all of mathematics.

*2. Pi has about 6.4 billion known digits which would take a person roughly 133 years to recite without stopping. The world record holder for the most memorized digits of Pi took nine hours to recite over 44,000 digits of Pi.*

*3. We can never truly measure the circumference or the area of a circle because we can never truly know the value of Pi. Pi is an irrational number, meaning its digits go on forever in a seemingly random sequence.4. The “squaring the circle” method of understanding pi has fascinated mathematicians because traditionally the circle represents the infinite, immeasurable, and even spiritual world while the square represents the manifest, measurable, and comprehensive world.5. Egyptologists and followers of mysticism have been fascinated for centuries by the fact that the Great Pyramid at Giza seems to approximate pi. The vertical height of the pyramid has the same relationship to the perimeter of its base as the radius of a circle has to its circumference.6. One of the earliest known records of pi was written by an Egyptian scribe named Ahmes (c. 1650 B.C.) on what is now known as the Rhind Papyrus. He was off by less than 1% of the modern approximation of pi (3.141592).7. In 2002, a Japanese scientist found 1.24 trillion digits of pi using a powerful computer called the Hitachi SR 8000, breaking all previous records.8. There are people who believe that Pi contains the answer to the universe, or that information is held in the digits. It has even been suggested it contains the Voice of God. In Carl Sagan’s book ‘Contact’ the places of Pi are found to contain a message from the beings that built the universe.*
