The word 'revolution' is fundamentally paradoxical: it literally means 'coming full circle' but is used to describe sudden, radical change into something new.
The host notes that the word 'revolution,' popularized by Copernicus to mean completing an orbit or coming full circle, is used to describe the opposite — overthrowing the old regime and setting out on a new path. He also corrects his earlier claim that Copernicus coined the word, noting pre-Copernican usage in Latin and Old French from 1390.

Mike Duncan: Because first of all, the word revolution, coined by Copernicus in 1543, is supposed to mean completing an orbit, coming full circle. Okay, so right off the bat, I would rewrite this opening to say something like, popularized by Copernicus, not coined by Copernicus. I'm looking at the Oxford English Dictionary right now, and they've got the first references to revolution coming out of Latin and Old French as early as 1390, with smatterings of additional references in the 1400s and early 1500s, all predating Copernicus.
