10 interesting facts about Pi
- π (Pi) is an irrational number, which means that its value cannot be expressed exactly as a fraction m/n, where m and n are integers. Consequently, its decimal representation never ends or repeats.
- It is also a transcendental number, which implies, among other things, that no finite sequence of algebraic operations on integers (powers, roots, sums, etc.) can be equal to its value.
- The Greek letter π, often spelled out pi in text, was adopted for the number from the Greek word for perimeter "περίμετρος", first by William Jones in 1707, and popularized by Leonhard Euler in 1737.
- In 1737, Euler used the symbol for pi to be equal to the ratio of the circumference to the diameter in a circle.
- The value of pi with first 100 decimal places is: 3.1415926535897932384626433832795028841971693993751058209749445923078164062862089986280348253421170679.
- The name of the Greek letter π is pi, and this spelling is commonly used in typographical contexts when the Greek letter is not available or its usage could be problematic.
- Satan doesn’t appear in Pi to quick, the first time 666 appears is at position 2440.
- Throughout the history of mathematics, there has been much effort to determine π more accurately and to understand its nature; fascination with the number has even carried over into non-mathematical culture.
- Pi has no zeros in the first 31 digits.
- No-one and no machine has been able to find out the exact value of Pi; people have been trying to pin an exact value to Pi for thousands of years.
