...helium ship Dessau, with 486 steel cylinders aboard, each accommodating 5,600 cu. ft. of highly compressed gas, docked at Houston, Tex., ready to take back to Germany the first installment. Ambassador Wilson was reminded that Germany had gone to "considerable expense" to revamp the LZ-130 from hydrogen to helium. Last week it became known in Washington that President Roosevelt had taken the question under personal consideration after the Departments of State and the Interior had split...
...produced a chemical known as methylcholanthrene, a complex compound of hydrogen and carbon which is very powerful in producing cancer in test animals. This chemical can also be obtained from the bile acids of the human body; therefore, cancer cay be the result of abnormal physiological actions which lead to the manufacture within the body of some chemical of the methylcholanthrene type...
Colorless, odorless, non-inflammable helium gas, with 92% of hydrogen's lifting power, is so far produced in large commercial quantities only at the 18-acre Government plant at Soncy, seven miles from Amarillo, Tex. There by a complicated process of washing, cooling, and separation it is extracted from the natural gas underlying that area. Present production is about 5,000,000 cubic feet out of a 24,000,000 cubic foot annual capacity-with reserves estimated at enough for the next 5,000 years. Two other small plants in the U. S. at Dexter, Kans. and Thatcher, Colo...
Physicists probing within the atom toward the ultimate constitution of matter already had their hands full with positive and negative electrons, neutrons (uncharged particles), protons (nuclei of hydrogen atoms), deuterons (nuclei of doubleweight hydrogen), tritons (nuclei of tripleweight hydrogen), alpha particles (nuclei of helium), and the theoretical but necessary neutrino (little neutron...
Some scientific discoveries are made because they were theoretically predicted and diligently looked for. Such was the discovery of the planet Pluto whose existence and probable orbit were indicated by irregularities in the orbits of other planets. So, too, deuterium (heavy hydrogen) was identified because its discoverer already had intimations of its existence, and the positive electron was foreshadowed in the cogitations of at least one mathematician before its track turned up in the laboratory. In fact, some things are made use of even before they are discovered - e.g., the little uncharged particle called the neutrino which atomic physicists need...
