...Harvard clock a thin trickle of hydrogen gas flows through an apparatus that splits its two-atom molecules into single atoms. Each of these atoms has one proton and one electron, but some of them have slightly more energy than the others because their electrons are spinning in a different way. When the atom stream shoots through a system of magnets, the low-energy atoms in it are deflected sideways while the high-energy ones converge, pass through a small hole in a 6-in. quartz bulb. The bulb is lined with paraffin which does not affect the atom...
...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...
...proposal calls primarily for common ownership of expensive theatrical equipment, such as lighting apparatus, stage risers, and stage construction tools. By combining their efforts, House societies could reduce budgets and thus expand programs, Phillips said...
Professor Groth says that existing centrifuges require only one-tenth as much electric power as diffusion apparatus of the same capacity. The present Degussa model can be built for about $1,000. and according to Zippe, it will produce in one year about one pound of U-235. Improvements already in sight will increase this figure. Both Groth and Zippe believe that centrifuges will eventually compete economically with gaseous diffusion in making nuclear fuel, enriched in U-235, for atomic power plants...
Blood-Red Heart. Light and radio waves are both electromagnetic. But light waves are very much shorter and therefore have much higher frequency. They cannot be generated, tuned, filtered or amplified by the handy electronic apparatus used for radio waves. The new maser techniques promise, at least theoretically, to harness light waves just as radio waves have been harnessed...
