Famous quotes containing the words world and/or tour:
“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)
“Left Washington, September 6, on a tour through Ohio, Kentucky, Tennessee, Georgia, and Virginia.... Absent nineteen days. Received every where heartily. The country is again one and united! I am very happy to be able to feel that the course taken has turned out so well.”
—Rutherford Birchard Hayes (1822–1893)
