Ancient astronomers noticed that the stars in the sky, which circle the celestial pole every day, seem to advance in that circle by approximately one-360th of a circle, i.e. one degree, each day. Primitive calendars, such as the Persian Calendar used 360 days for a year. Its application to measuring angles in geometry can possibly be traced to Thales who popularized geometry among the Greeks and lived in Anatolia (modern western Turkey) among people who had dealings with Egypt and Babylon.
That means a complete turnaround

Hmmm. That must be an American expression. I've always said that "a complete turnaround" is 180 degrees. For example, your football team sucks, but they improved drastically (to the exact opposite of the circle, or 180 degrees). If they do a 360, they go past being better and end up where they started, sucking.
Interesting.
