...polite truth or a romantic stage presence which melts in the wings into a conservative reality. If this is what the American people want there are American "folk singers" who chant Russian peasant songs to the accompaniment of periodic taps on the dashboard of a Mercedes sedan, or emit plantation work songs out over the violin section from the confines of tight black pants and silk shirts. These are the part-time romantics who make their deliveries without the "Alice-in-Wonderland logic" and with all the power and effectiveness of half the critical mass. The public, in its approach...
...physical bodies emit heat in the form of infra-red rays invisible to the human eye. Out of this simple scientific fact has grown an exciting and important new industry that is already big in missile and space work. Unlike more familiar uses of infra-red-which use it as a heat source to cook foods quickly-the new applications need supersensitive detection equipment to receive infra-red and "see" the source it comes from. Infra-red detection now adds a new dimension to sight...
Like the creak of wheels on a horse-drawn cart or the dry wheeze of a hand-cranked auto engine, the familiar ring-a-ling of the telephone will soon be only an echo of the past. The telephone of the future will emit four staccato baritone beeps-and this week, in the homes of 300 residents of Morris, Ill., a farming center 75 miles southwest of Chicago, the beep of tomorrow could already be heard. Using Morris as a pilot project, Bell Telephone Laboratories have installed telephones that...
...about 4 trillion particles enter the bulb in one second, the agitated gas gets dense enough to support a sort of chain reaction. A few atoms spontaneously lose their extra energy, which they emit in the form of photons (units) of radio microwaves about 21 cm. (8.3 in.) long. The newborn photons hit other hydrogen atoms and make them emit photons too. Then a pulse of microwaves bursts from the bulb and is gathered as high-frequency current by apparatus outside...
Then a sort of chain reaction happens. A few atoms drop spontaneously to the lowest energy level, emitting photons (units) of deep red light. The photons hit other chromium atoms, knocking them off their energy shelf and making them emit more photons of red light. The photons that move sideways escape from the rod, but a few of them hit its polished ends, which the scientists have covered with a thin film of silver that reflects nearly all of them back into the rod. This reflected light moves lengthwise between the two end mirrors, traversing .all of the ruby...
