Among modern astronomers, an old theory of the origin of the solar system was back in fashion. German Philosopher Immanuel Kant had speculated in 1755 that the sun and its planets were formed by condensation out of a gaseous cloud. For a while astronomers supported Kant, but later his "nebula hypothesis" lost scientific favor. More modern astronomers, notably Sir James Jeans, have conceded that the sun may have been formed that way, but not the planets. To explain the planets, Jeans suggested that another star must have grazed the sun, pulling out a thread of sun-matter that gathered into...
...which differ only in atomic weight. Since the isotopes are identical chemically, they cannot be separated by chemical means. They must be separated by some process taking advantage of their slightly different atomic weights. The job is extremely difficult and laborious, but the U.S. developed two processes (gaseous diffusion and electromagnetic separation) that worked efficiently...
Some of the photographs show that the sun, though completely gaseous, has mountains-vast mounds of luminous gas as much as 100 miles high. The mounds seem to have some connection with sun spots (solar hurricanes), but they often appear before the spots break through the sun's surface and they persist long after the spots have disappeared. Around the peaks and valleys of these gaseous mountains blow winds whose speed may be greater than 300,000 m.p.h...
Each working day, Los Angeles oil refineries and other processing plants spew out a mixture of gaseous wastes containing about 800 tons of sulphur dioxide. As it rises into the air, the sulphur dioxide combines with water vapor and oxygen to form sulphuric acid. The minuscule droplets pick up more water and a variety of solid particles (e.g., soot, dust), until the City of the Angels wears, instead of a halo, a hat of dirty grey smog...
...beginning of the test, the gaseous outpourings of Alabama's man-made inferno were drawn off at Borehole No. 2, limiting the combustion to the first 300-ft. stretch. The underground temperature went up to 900° F. Later it might go as high as 3,000° F. No immediate attempt was made to produce a useful, combustible gas: the first thing was to see how steadily the coal could be made to burn. Later, hot air, steam or oxygen could be fed into Borehole No. 1 to make a variety of gases with different chemical and thermal...
