Pi, represented by the Greek letter π, is a mathematical constant approximately equal to 3.14159. It's the ratio of a circle's circumference to its diameter and appears in many mathematical and physics formulas.

*Key Properties:*

- *Irrationality*: Pi is an irrational number, meaning it can't be expressed exactly as a ratio of two integers.

- *Transcendence*: Pi is a transcendental number, making it impossible to solve the ancient challenge of squaring the circle with a compass and straightedge.

- *Random Digit Distribution*: Pi's decimal digits appear randomly distributed, but no proof of this conjecture has been found.

*Approximations:*

- *Integers*: 3

- *Fractions*: 22/7, 333/106, 355/113

- *Decimal Digits*: 3.14159 26535 89793 23846 26433...

*History:*

- Ancient civilizations, including Egyptians and Babylonians, approximated Pi for practical computations.

- Greek mathematician Archimedes developed a polygonal approach to approximate Pi around 250 BC.

- Mathematicians have attempted to extend their understanding of Pi for thousands of years ¹#NewsTrade
