Famous quotes containing the words single and/or crystals:
“Sheriff, have you ever watched a friend dying before your eyes and not been able to help? That’s the worst of it. Being helpless. It’s particularly tough when you’re a physician and you know what’s wrong with him, and there isn’t a single solitary thing you or anyone else can do.”
—Robert M. Fresco. Jack Arnold. Prof. Gerald Deemer (Leo G. Carroll)
“It is clear that everybody interested in science must be interested in world 3 objects. A physical scientist, to start with, may be interested mainly in world 1 objects—say crystals and X-rays. But very soon he must realize how much depends on our interpretation of the facts, that is, on our theories, and so on world 3 objects. Similarly, a historian of science, or a philosopher interested in science must be largely a student of world 3 objects.”
—Karl Popper (1902–1994)
