The image is more than an idea. It is a vortex or cluster of fused ideas and is endowed with energy.
A single Dallas Cowboys football game uses up as much electricity as the entire nation of Liberia in those same three hours - one reason the globe, if looked at from a certain height, is a cluster of lights surrounded by enormous patches of dark.
The genesis of a poem for me is usually a cluster of words. The only good metaphor I can think of is a scientific one: dipping a thread into a supersaturated solution to induce crystal formation. I don't think I solve problems in my poetry; I think I uncover the problems.
The new industries are brainy industries and so-called knowledge workers tend to like to be near other people who are the same. Think of the City of Hollywood. People cluster. This means you have winning regions, such as London and Cambridge, and losing regions. The people who want to be top lawyers in Sunderland are hoovered up by London.
If you take a galaxy and try to make it bigger, it becomes a cluster of galaxies, not a galaxy. If you try to make it smaller than that, it seems to blow itself apart.
Most of us cluster somewhere in the middle of most statistical distributions. But there are lots of bell curves, and pretty much everyone is on a tail of at least one of them. We may collect strange memorabilia or read esoteric books, hold unusual religious beliefs or wear odd-sized shoes, suffer rare diseases or enjoy obscure movies.

Our financial services and insurance cluster is one of Delaware's key economic drivers in the state.
You cannot eat a cluster of grapes at once, but it is very easy if you eat them one by one.
