10 interesting facts about Pi


1) Pi is the most recognized mathematical constant in the world, being considered the most important and intriguing number in all mathematics.

2) The symbol for pi () has been used regularly in its mathematical sense only for the last 250 years.

3) We cannot accurately measure the circumference or area of ​​a circle because we will never truly know the value of pi. Pi is an irrational number, so its digits are a seemingly random sequence.

4) In the Star Trek episode, "Wolf in the Fold", Spock launches the evil computer by ordering it to compute the value of pi to the last digit.

5) Egyptologists were fascinated that the Great Pyramid of Giza seems to approach pi. The vertical height of the pyramid has the same relation to the perimeter of its base as the radius of a circle has to its circumference.

6) Darren Aronofsky's fascinating movie (Pi: Faith in Chaos) shows how the main character's attempt to find simple answers about pi (and, by extension, the universe) drives him crazy. The film won the Director Award at the 1988 Sundance Film Festival.

7) In the Greek alphabet, is the sixteenth letter. In the English alphabet, p is also the sixteenth letter.

8) In 1995, Hiroyuki Goto memorized 42,195 pi houses, setting a new world record at the time. Currently, another Japanese, Akira Haraguchi, has memorized 100,000 digits. Some scholars speculate that Japanese is better suited than other languages ​​for memorizing sequences of numbers.

9) The first 144 digits of pi add up to 666 (what many say is "the mark of the Beast"). E 144 = (6 + 6) x (6 + 6).

10) In 2002, a Japanese scientist found 1.24 trillion digits of pi using a powerful computer called Hitachi SR 8000, breaking all previous records. With our current technology, pi has been calculated to be more than eight quadrillion decimal places after the comma.
