The Beauty of a Circle
While I was running this evening, and my mind was wandering, I thought about the phrase a nice round number. I wondered to myself why we call them round numbers. And then almost straight away I answered my own question and said that it’s obviously because of the zero. Which is round. And round numbers always end in a zero.
Well, that’s that. Sometimes the answer is just that simple, and I’m even able to figure it out myself. Not that that stopped me thinking about numbers, and roundness of course.
