Famous quotes containing the words grown and/or crystals:
“There’s in people simply an urge to destroy, an urge to kill, to murder and rage, and until all mankind, without exception, undergoes a great change, wars will be waged, everything that has been built up, cultivated, and grown will be destroyed and disfigured, after which mankind will have to begin all over again.”
—Anne Frank (1929–1945)
“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)
