Kekule, dream, and benzene

There’s an old story that Kekule dreamed of a snake swallowing its tail (an Ouroboros), and from that he made the creative jump that benzene is formed in the shape of a ring. There are quite a few articles on this, but the link shown at least attempts to put a little research behind this in the first few paragraphs.

I was reminded of this when reading this article where Isaac Asimov writes about what he thinks creativity is, or more accurately, how to create conditions where creativity might thrive.
