It's here!!!!

It's here!!!!

March 14, 2011, also known as pi day, is almost upon us.  It is called pi day because if you write it out in numbers it is 3.14, which is the commonly used abbreviation for pi (Π).  So in honor of pi day I thought I would do 50 fun facts about pi (this is also my homework for Ms.Miskelly, but I only need 1 fact for that so yeah. Do I get extra credit?) so here they are:

  1. Pi is the number of times a circle’s diameter will fit around a circles circumference.
  2. Circles have an infinite number of corners unlike people say.
  3. Pi’s number sequence has passed all randomness tests (in plain English: it’s not random)
  4. 22/7, a commonly used fraction for pi, is equal to .04025%
  5. A Fraction used as an approximation to pi is 355/113 which is accurate to 00000849%
  6. The most accurate fraction of Pi is104348/33215. This is equal to 00000001056%.
  7. The first 31 digits of pi contain no zeroes.
  8. Hundreds of equations include pi, including those that explain the double helix in DNA, the way water ripples when hit with a rain drop, and the distributing of factors. 
  9. Pi is an irrational number.
  10. In 1991 the first 2,260,321,363 numbers were found.  That was as far as they got.
  11. Pi is the 16th number in the Greek alphabet.
  12. If one billion digits of pi were printed in average it would go from NYC to the middle of Kansas (this has been tested).
  13. The Feynman Point has 6   9’s in a row.
  14. If you take 10 million digits of pi (in order) you will get exactly 200 sets of 5 didets that are the same in a row.
  15. Pi and the letter “p” are both 16 th letters, just in different alphabets.
  16. The first 144 digits in pi add up to 666
  17. A British crop circle in 1998 depicted a coded image that represented the first 10 digits of pi.
  18. Plato found a fairly accurate formula for pi:√2+√3=3.146
  19. Albert Einstein was born on pi day (3/14/1879)
  20. The official celebration of pi day starts at 1:59 to represent 3.14159.
  21. The earliest record of pi is on the Rhind Papyrus and is only 1% off of today’s calculation.
  22. Pi has been studied by humans for almost 4000 years.
  23. The 359-340 digits are the numbers 360 which is equal to the number of degrees in a circle.
  24. Even computers can’t compute pi, so don’t feel bad if you can’t.
  25. The current pi champ memorized 42,195 digits in 1995.
  26. The vertical height of the Great Pyramid of Giza times 3.14 equals the perimeter of the base.
  27. If you tried to calculate the circumference of the earth using π rounded to only the ninth decimal place, a mistake of less than one quarter of an inch in 25,000 miles would occur.
  28. It is impossible to find the circumference of a circle without knowing the true value of pi.
  29. During famous O.J. Simpson trial, there were fights between defense attorney Robert Blasier and an FBI agent about the actual value of pi, that seemed to reveal mistakes in the FBI agent’s smarts.
  30. A fancy cologne named Pi is marketed as highlighting the attraction to smart guys.
  31. The symbol for pi has been used in math for only 250 years.
  32. The comedian John Evans once said: “What do you get if you divide the circumference of a jack-o’-lantern by its diameter? Pumpkin π.”
  33. In one episode of Star Trek, Spock fools a computer by asking it what the last digit of pi was.
  34. Pi is the most recognized math symbol in the world.
  35. Pi is also a food, but that is spelled p-i-e.
  36. It took a Hitachi SR 8000 supercomputer over 400 hours to compute pi to 1.24 trillion digits.
  37. Some scientists believe Japanese is the best language to memorize pi.
  38. Pi is mentioned in the bible 1 Kings 7:23.
  39. Pi was first intensely studied by one of the greatest mathematicians of the ancient world, Archimedes of Syracuse. Archimedes was so engrossed in his work that he did not notice that Rome had taken Syracuse. When a Roman soldier approached him, he yelled in Greek “Do not touch my circles!” The Roman soldier simply cut off his head and went on his business.
  40. Ancient mathematicians tried to compute pi by inscribing polygons with more and more sides that would more closely approach the area of a circle. Archimedes used a 96-sided polygon. Chinese mathematicians Liu Hui inscribed a 192-sided polygon and then a 3,072-sided polygon to calculate pi to 3.14159. Tsu Ch’ung and his son inscribed polygons with as many as 24,576 sides to calculate pi (the result had only an 8-millionth of 1% difference from the now accepted value of pi)
  41. William Jones introduced the symbol “π” in the 1706. But Leonhard Euler made it popular in 1737.
  42. Before the π symbol was used, mathematicians would describe pi in round-about ways like “the quantity which, when the diameter is multiplied by, yields the circumference.
  43. Some people claim that we are programmed to find patterns in the world because it’s the only way we can give meaning to the world and ourselves. Hence, the obsessive search to find patterns in pi.
  44. Pi is also referred to as the “circular constant,” “Archimedes’ constant,” or “Ludolph’s number.”
  45. The first six digits of pi (314159) appear in order at least six times among the first 10 million decimal places.
  46. John Donne’s (1572-1631) poem “Upon the Translations of the Psalms by Sir Philip Sidney, and the Countess of Pembroke, His Sister” condemns attempts to find an exact value of pi, or to “square a circle,” which Donne views as an attempt to rationalize God:

    Eternal God—for whom who ever dare
    Seek new expressions, do the circle square,
    And thrust into straight corners of poor wit
    Thee, who art cornerless and infinite—
  47. Thirty-nine decimal places of pi suffice for computing the circumference of a circle girding the known universe with an error no greater than the radius of a hydrogen atom.
  48. 3.141592653589793238462643383279502884197169399375105820974944592307816406286208998628034825342117067 is the first 100 decimal places in pi.
  49. A businessman in Cleveland, US published a book in 1931 to announce the value of pi is 256/81.
  50. In the first 6,000,000,000 numbers of pi
  • 0 occurs 599,963,005 times
  • 1 occurs 600,033260 times
  • 2 occurs 599,999,169 times

Those are my 50 fun facts about pi.
