This distinction led to nearly disastrous consequences during hurricane Katrina as pilots flying into unfamiliar airports did not properly interpret their sectional map and communicated on the wrong frequency. UNICOM airports never have an operating control tower.

Famous quotes containing the word world:
“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)
“At present, man applies to nature but half his force. He works on the world with his understanding alone. He lives in it, and masters it by a penny-wisdom; and he that works most in it, is but a half-man, and whilst his arms are strong and his digestion good, his mind is imbruted, and he is a selfish savage.”
—Ralph Waldo Emerson (1803–1882)
