Popper Pack

Famous quotes containing the words popper and/or pack:

“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)

“What’s the use of worrying?
It never was worth while,
So, pack up your troubles in your old kit-bag,
And smile, smile, smile.”
—George Asaf (1880–1951)
