A fact in itself is nothing. It is valuable only for the idea attached to it, or for the proof which it furnishes.

Claude Bernard

We achieve more than we know. We know more than we understand. We understand more than we can explain.

A great discovery is a fact whose appearance in science gives rise to shining ideas, whose light dispels many obscurities and shows us new paths.
