Simple, isn’t it?
Pi has been an important part of mathematics for centuries, and there have been many thinkers who have tried to calculate its exact form. The first mathematician to calculate pi to several decimal places was a Greek in ancient times . By calculating the circumference of more and more polygons drawn in a circle, he was able to narrow down the ratio of pi with astonishing precision. In the 5th century, the Chinese mathematician Zu Chongzhi specified pi to seven decimal places. But do you know the name of the Greek mathematician?
Incidentally, the Greek letter π only really became popular in the 18th century thanks to the famous mathematician. Before the Swiss used the letter, there were various other symbols and spellings for pi. He first used the Greek letter π in his works in 1737 to represent the ratio of the circumference of a circle to its diameter. The symbol quickly became the standard term in mathematics. Do you know which famous mathematician this is?
