...Says he: there is a strep-polio axis-somehow, in ways no doctor understands, streptococcus plays a malignant part in infantile paralysis. (A coccus is a round bacterium large enough to be seen with an ordinary microscope. A virus is so small it can be seen only with an electron microscope, has some bacteria-like and some protein-like qualities-no one knows for sure whether it is living matter or a chemical...
...respect: he was formerly director of the famed Physical Institute of the University of Vienna. He is also a noted heretic. In 1910 he tangled with Caltech's brilliant Robert Andrews Millikan, then a young professor at the University of Chicago, who had just isolated and measured the electron. Ehrenhaft said that he himself had isolated electrical particles of various sizes, many of them smaller than the electron. Millikan demolished Ehren-haft's proofs, won the Nobel Prize...
...current. His results suited another youngster, 27-year-old James T. Kendall of England's Metropolitan-Vickers laboratory. Dr. Kendall declared in Nature that Ehrenhaft's claims "may turn out to be no more valid than his previous claims of the existence of charges smaller than the electron...
Hillier's analyzer, like the electron microscope, does its job by bombarding a substance with electrons. It has an electron "needle" of extremely fine focus. Hillier first lines up his minute target (such as the head or tail of a virus) by means of the microscope, then needles it with an electron stream of some 50,000 volts. This dislodges electrons from the atoms in the target. Since the energy required to dislodge them varies with the kind of atoms present, the loss of energy in the bombarding electrons after they pass through the substance indicates the nature...
...full significance of the electron microanalyzer is not yet clear, but instruments opening new vistas into the infinitesimal have always led to practical results...
