...Suits passed a brilliant arc between two electrodes of a welding torch in an atmosphere of hydrogen. This was magnified and projected in color on a frosted glass screen. The engineers saw the images of the electrodes three inches apart, with the broad, vivid flow of the arc two inches wide. Then Dr. Suits produced an arc in an atmosphere of nitrogen. The arc band was pale, thin. But when he stepped up the nitrogen pressure to 1,200 Ib. per sq. in., the arc thickened and brightened until it was indistinguishable from that produced in hydrogen...
Stanley showed. The biggest known, they weigh 17 million times as much as a hydrogen atom, nearly one million times as much as a molecule of water. Left by themselves they are inert. But in contact with living plant or animal material they multiply incessantly. Under some conditions the virus protein molecule changes its inner structure all by itself. It then causes a totally different disease...
...living cell. The high energy carried on the photon swings the electrons of the cell up to correspondingly high energy levels which represent temperatures of 1,000,000°. This lasts for only some .00001 sec., but large protein molecules may be broken up, carbon dioxide and hydrogen given off, and water molecules in the cell oxidized to hydrogen peroxide. The cell may then sicken and die. If it is a cell in the reproductive germ plasm, a mutation or hereditary change may occur...
...Birkhoff system, the hydrogen atom is contemplated as a mixture of two "perfect fluids"-the positive electricity of the nucleus, the negative electricity of the surrounding electron. The disturbance created in the fluids by a particle or light rav from outside can be expressed, very roughly speaking, as though they were water rippled by a falling stone. Furthermore, the expression can be formulated in Relativistic terms. Whether atoms with more than one electron can be crammed into the same mold remains to be seen...
...imaginative persons have suggested that the outpouring of injurious ultraviolet radiation may be so strong that human beings would have to carry umbrellas coated with lead before venturing under the glare of "Nova Cassiopeiae." Other highlights of the astronomers' convention: Nos- 60, 61, 62. In the sun hydrogen, helium, calcium, sodium, carbon, nitrogen, and many another terrestrial element have been identified by comparing the solar spectrum with very clear spectra of substances photographed in the laboratory...
