Suppose you want to be a great archeologist, and you join a successful archeologist as a student assistant, and he tells you where to dig. You dig up a marvelous discovery. Now I ask you, who should get the credit: the director or the digger?

I think the intuitive processes of discovery are the same, very much the same, in the arts as in the sciences.

The artist must ask you to think of the world in a different way, and sometimes it's a more abstract way; sometimes it's a completely different kind of colouring.

The problem is how do molecules react. Because if you want to transform a molecule into something useful or something you're interested in, it helps a lot to understand the structure. That means you can explore much more complicated systems, much more complicated reactions.
