Throughout history mankind has used pi, the ratio between a circle’s circumference and its
diameter. 4,000 years ago pi was discovered and today is applied to everyday life. Pi
can be applied to things in many different ways and the early calculations were different
depending on the culture.



In 2,000 b.c. the Babylonians recognized pi. They estimated pi at 3.1250. Later the
Egyptians and Chinese would continue the research of Pi and calculate pi as 3.1605 and
3.0. 1,500 years later (500 B.C.) the Greeks began an extensive research on geometry.

Johann Hienrich Lambert proved that Pi was irrational and couldn’t be calculated exactly.
In Present day, Pi is calculated near 3.14.
