What is a whale's spout made of? One theory: the spout is condensed vapor from the whale's moist breath. But in the tropics, where breath does not condense, the whale's spout is just as visible as in arctic cold. In Britain's Nature, Dr. F. C. Fraser and P. E. Purves tackle the old controversy again...
Orange "G." As the rocket rose to almost 70 miles, the high-altitude winds distorted the sodium-vapor trail into a gigantic "G" 20 miles across. It remained visible for 15 minutes, until the shadow of the earth reached it, and was seen in Amarillo, Texas, 300 miles away...
...putting a known amount of sodium vapor into the atmosphere at a known altitude, the sodium rocket will enable scientists to learn more about the natural sodium that is already there. They can compare the air glow coming from the two lots of sodium, and since the amount of one is known, the amount of the other may be calculated...
...sodium vapor that the Air Force put into the atmosphere will drift with the winds. If it increases the normal air glow, it can be followed, perhaps for considerable distances. A cloud of sodium of known origin picked up by astronomers' instruments in the Eastern states will be a fine way to measure wind velocity at levels that no weather balloon can reach...
...week by Alco Products Inc. Alco and Manhattan's Stone & Webster Engineering Corp. will start building the $2,096,753 plant this year at Fort Belvoir, Va., where it will be used to train Army engineers in atomic power-station construction and maintenance. The reactor, housed in a vapor-tight steel shell, will turn water into steam, light 600 houses. A single charge of atomic fuel will run the reactor for 18 months. In an emergency, it can be hooked up to a conventional steam-generating plant...
