The Muse
Here is what Rick looks like as he walks in circles around his office's office space: the extremity of his clock's second-hand.
Here is what else Rick looks like, as he continues this circle or more-or-less circular movement: a planet or moon, orbitting a star or planet.
Where is Rick's centre of gravity, if this last analogy is continued? - A spot slightly offset from the room's centre.
Where is the centre of gravity of the second-hand's extremity?: The clock's own centre, the only spot on its face to which no implication of time can be imputed.
What is Rick's own centre of gravity, around which he orbits?
