The most exciting phrase to hear in science, the one that heralds new discoveries, is not “Eureka!” (I found it!) but “That’s funny ...”

Our scientific power has outrun our spiritual power. We have guided missiles and misguided men.

Science is not ... a perfect instrument, but it is a superb and invaluable tool that works harm only when taken as an end in itself.

After a certain high level of technical skill is achieved, science and art tend to coalesce in esthetics, plasticity, and form. The greatest scientists are always artists as well.
