By suppressing undesirable recessive characteristics in the crossed plants, hybridization produces hardier, more vigorous offspring. Crossbreeding has been extended to other...
Operation Crossroads had been ballyhooed as the greatest laboratory experiment in all history. To the listening world, it sounded like an animal circus at feeding time. Static almost drowned out other sound effects: a dozen Donald Ducks quacked endlessly and often pointlessly.
The modern theory of wave mechanics, which holds that units of matter (e.g., electrons and protons) behave partly like particles, partly like waves, rests on a revolutionary electron experiment performed by Clinton J. Davisson and Lester H. Germer in 1927. Their experiment, done with crystals, was analogous to shooting a...
To the great surprise of classical physicists, the electrons, recorded on a screen after they went through the holes, made a wave "interference" pattern. The experiment proved that, somehow, each electron went through both holes at once. The discovery, a great blow to the notion that matter is indivisible, led...
From the viewpoint of practical Washington politics, it is paradoxical that reciprocal trade agreements are signed with Czechoslovakia that put Czech shoes in competition with Massachusetts shoes, while this same type economic fillip is denied a country linked to the U.
