...British concluded that magnesium incendiary bombs would behave the same way. But the metal in real bombs is only 80% magnesium. The rest is an alloy to make them tough enough to penetrate roofs. The alloyed magnesium burns much less intensely than the pure metal, which can take oxygen as readily from water as from...
...reported to the American Astronomical Society last week that star "shells" are made of the same elements as stars themselves. They found that the planetary nebulae, which are great clouds of gas surrounding the very hot O-type stars, are composed chiefly of hydrogen, helium, carbon nitrogen, and oxygen...
...same five elements which play the important role of furnace men in the sun and most other stars. In the well-established carbon cycle, originally proposed by Dr. Hans Bethe of Cornell University, hydrogen is the fuel and helium the ash of stars, while carbon, nitrogen, and oxygen are the elements which keep the process going...
...make sponge iron, ore is not smelted. It is mixed with pulverized coal (natural gas can also be used) and coke, then fed to a large rotary kiln. When the kiln is heated to 1,800°F., the powdered coal first robs the ore (iron oxide) of its oxygen, then turns into gas, leaving fairly pure iron granules which have a spongy texture. This stuff can then be fed to the steel furnaces...
...insects, as Naturalist Julian Huxley explains, microscopic air tubes carry oxygen "directly to and from the tissues instead of using dual mechanisms of lungs and blood stream. Laws of gaseous diffusion are such that [this system] is extremely efficient for very small animals, but becomes rapidly less efficient with increase of size, until it ceases to be of use at a bulk below that of a house mouse. [So] no insect has become moderately large by vertebrate standards or moderately intelligent." If the termite had a proper trachea, man might never have appeared on earth...
