"The philistine fixation with temporary utility is swamped in the long run by the enduring power of ideas. And just one discovery such as calculus, gravity or democracy will pay for a lot of research.
"Of course, there is a lot of bad and useless research. But as the Polish example illustrates, it is difficult to decide which research is useless or how research will influence our lives."
-John Kay, as excerpted from this article
