...casing-head process," next by "cracking," finally by hydrogenation. Cracking, of which hydrogenation is a continuation, consists of breaking down the molecular structure of heavy crude oil into a number of lighter, more salable derivatives such as kerosene and gasoline. Polymerization is the reverse; it takes the very lightweight, gaseous fractions of petroleum, which were formerly wasted or used only in restricted ways,* and through pressure, heat and catalytic agents builds them into heavier molecules for high-test (antiknock) gasoline...
...life of planetary nebulae has been found by Fred L. Whipple, instructor in Astronomy, to be, on the average, about 30,000 years. These bright bodies with their large and rapidly expanding gaseous envelopes, develop in the manner of exceptionally slow novae...
...than average luminosity, is rather on the small side as stars go, being officially classed as a "yellow dwarf." For a really big star astronomers look to Antares, a red supergiant 400,000,000 miles in diameter. All stars are globes of hot gas. Antares is relatively cool, its gaseous density very low. Thirty-seven thousand cubic feet of its star-stuff, if concentrated and brought to earth, would weigh only one pound. Yet up to last week it held rank as the largest star known to astronomy...
...associates have produced 20 grams of heavy nitrogen in 2½% concentration, 400 grams of lower concentrations. To obtain it they used a 35-ft. vertical tube designed by Columbia's George B. Pegram for the separation of heavy oxygen. The tube contains 1,200 steel cones. A gaseous compound of ammonia, rich in nitrogen, passes up through the tube; some condenses, trickles down and with each fall from cone to cone the concentration of heavy nitrogen becomes richer...
...believes that the whole Milky Way; was once a nebulous cloud of gas in random motion, in which large clumps condensed because of differences in the gaseous viscosity. Thus a sun and its planets might be formed at the same time, and the original motion of the gas plus the forces of gravitational attraction would provide the motion for planetary revolution...
