History of Pi
The history of Pi is as infinite as the number itself. The earliest known approximations date back to ancient civilizations. The Egyptians and Babylonians, around 2000 BC, used values of Pi ranging from 3.125 to 3.16. However, it was the ancient Greeks who significantly contributed to the understanding of Pi.
Archimedes of Syracuse, a Greek mathematician, is often credited with the first rigorous calculation of Pi. He approximated Pi by inscribing and circumscribing polygons around a circle, eventually arriving at a value between 3.1408 and 3.1429. This method laid the groundwork for future mathematicians.
Over the centuries, various cultures continued to refine the value of Pi. In the 17th century, mathematicians like John Wallis and Isaac Newton began using infinite series to calculate Pi more accurately. Today, we have computed Pi to trillions of digits with the aid of modern technology.
