Famous quotes containing the words single and/or crystals:
“After that came commencement day—that great day for which all other days were made. And it went. And that night I felt of myself all over, and to my astonishment, I found ‘twas the same old Rud. Not a single cubit added to my stature; not a hair’s breadth to my girth. If anything, on the contrary, I felt more lank and gaunt than common, much as if a load were off my stomach.”
—Rutherford Birchard Hayes (1822–1893)
“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)
