Circles and PiBabylon

As it happens, 360 degrees are one of the oldest concepts in mathematics we still use today. They were developed in ancient Babylon, more than 5000 years ago!

At that time, one of the most important applications of mathematics was in astronomy. The sun determines the four seasons, which farmers have to know about when growing crops. Similarly, the moon determines the tides, which was important for fishers. People also studied the stars to predict the future, or to communicate with gods.
