While it might seem strange at first, the connection lies in the idea of "turning around" or "circling."
* Revolution refers to a significant change or upheaval, often involving a complete overthrow of a system or government.
* Revolve literally means to move in a circle around a central point, like a planet revolving around the sun.
The link is metaphorical: a revolution is a turning point, a complete change in direction, much like a revolving object changing its position in space.
