Famous quotes containing the words grown and/or crystals:
“I pray we are still a young and courageous nation, that we have not grown so old and so fat and so prosperous that all we can think about is to sit back with our arms around our money bags. If we choose to do that I have no doubt that the smoldering fires will burst into flame and consume us—dollars and all.”
—Lyndon Baines Johnson (1908–1973)
“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)
