17559 | Is one atom a piece of gold, or is a sizable group of atoms required? [Inwagen] |
Full Idea: A physicist once told me that of course a gold atom was a piece of gold, and a physical chemist has assured me that the smallest possible piece of gold would have to be composed of sixteen or seventeen atoms. | |
From: Peter van Inwagen (Material Beings [1990], 01) | |
A reaction: The issue is at what point all the properties that we normally begin to associate with gold begin to appear. One water molecule can hardly have a degree of viscosity or liquidity. |
