...little symbol e representing a quantum began seriously to restrict the old free & easy mechanics. Nevertheless the work of reconciliation began. Denmark's Niels Bohr ingeniously yoked classical laws and quantum laws to predict the probable interorbital jumps of electrons. His famed Correspondence Principle was postulated in 1913, was later abandoned when it was found not to work for atoms having more than one electron...
...Speed Sirs: Your account of Professor Bohr's application of Professor Werner Heisenberg's concept of uncertainty to "everyday existence, where an inch is an inch, and a gallon is a gallon" (TIME, July 3, p. 40) recalled to mind an entertaining bit og testimony given in a lawsuit in which my father was counsel for one of the litigants. The case involved an automobile collision. Immediately before the collision, one of the automobiles had struck a cow; and during the trial it became important for the plaintiff to bring out the speed with which this...
Since this essential duality is true for atoms, reasoned Theorist Bohr, it must be true of all things out of which atoms are made. This general duality he called "complementarity," and proceeded to elaborate his thesis abstrusely. The net of his discourse was that if you live inside a ball, you cannot have any conception of its outside convexity, until you get outside. Then you cannot be sure of the internal concavity. Likewise you never can know all the causes of a specific result or all the effects of a single action. With uncertainty of cause & effect goes uncertainty...
...audience felt better when Professor Bohr, fiddling with a loudspeaker cord, short-circuited the apparatus and made it blare. It was much easier, and more pleasant, to understand round-faced young Professor Ernest Orlando Lawrence of the University of California tell how he transmuted elements with "deuton" bullets...
