(self.showerthoughts)
A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.
So Descartes coined the term specifically as a dig because he didn't see any geometric possibilty to the concept. The concept seems to have roots going back to ancient Egypt, but the modern inquiry goes to the Renaissance. I think Gauss wanted to call them laterals.
Thank you for adding some facts to my vague conflated memories.
