How the "revolution" came about

The ancient Babylonians estimated that it took 360 days for earth to complete one journey around the Sun. They made the year 360 days long. They said that one complete turn or revolution would be 360 degrees.

We still use the system introduced by the Babylonians to measure angles. Angles are measured in degrees.....One complete revolution is 360 degrees!!!
