Famous quotes containing the words liquid and/or crystals:
““Awake,
My fairest, my espoused, my latest found,
Heaven’s last best gift, my ever new delight,
Awake, the morning shines, and the fresh field
Calls us: we lose the prime, to mark how spring
Our tended plants, how blows the citron grove,
What drops the myrrh and what the balmy reed,
How nature paints her colors, how the bee
Sits on the bloom extracting liquid sweet.””
—John Milton (1608–1674)
“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)
