...Hahn bombarded his bit of uranium with neutrons in order to obtain ekarhenium, a heavy element similarly created some years ago by Italian Physicist Enrico Fermi. Hahn obtained ekarhenium, all right, and something else he did not expect, which he identified as atoms of barium and krypton. He applied the principles of quantum mechanics (atomic mathematics) to find out how much of a tempest in a test tube occurs when ekarhenium breaks up into barium and krypton. Answer: 200,000,000 volts...
Meanwhile, the Hahn report must have brought commingled pleasure and discomfiture to his colleague, crusty old Physicist Johannes Stark, who heads the Reich Physical-Technical Institute. Johannes Stark whoops up the Nazi idea that physical experiment is better than theory, regards theory as "Jewish" in spirit. Hahn's high-voltage explosion was produced by experiment, but accidentally; and it could never have been evaluated or even recognized without the help of theory...
...development of Alnico and other "age-hardening" alloys like it, permanent magnets were all quenched steels. In the newer alloys "magnetic hardness" is obtained by slow, controlled cooling. They provide more magnetic force at lower cost. The increased power of the Alnico magnet shown last week, designed by Physicist Wayne E. (for nothing) McKibben, is due to a steel sheath around it, which efficiently concentrates the magnetic flux very much as an optical lens focuses rays of light...
...state of U. S. psychological opinion on ESP was clarified last week by the results of a questionnaire published in Duke University's Journal of Parapsychology. Physicist Clarence C. Clark of New York University and a collaborator questioned 603 members of the American Psychological Association, got replies from 352. Of these, five agreed with Rhine that ESP was "an established fact." Of the remaining 347 who did not regard it as such, 142 voted it "merely an unknown," 51 "an impossibility," 128 "a remote possibility," 26 "a likely possibility...
Metallurgist L. R. Jackson and Physicist Howard Willis Russell of the Battelle Memorial Institute (Columbus, Ohio) realized that if they could vary the ingredients of an alloy so as to set the Curie point at any desired temperature, they would have a highly sensitive substance for thermostatic control. Experimenting with several mixtures, they finally got what they wanted with an alloy of iron, nickel, chromium, silicon...
