...following the clues of radio-activity that Drs. Pauli and Chadwick separately reached their conclusions. Recently Professor Walther Bothe of Giessen, Germany, bombarded the element beryllium with alpha particles. Something happened to the alpha particles. The particles contained four units of positive electricity (protons) and two of negative electricity (electrons) when they crashed into the beryllium. Two protons of an alpha particle seemed to cling to the nucleus of a beryllium atom (thereby theoretically transmuting that atom of beryllium into an atom of carbon). The particle's other two protons and the two electrons seemed changed into what Professor...
Secretary Hurley: I mean it hasn't one element of courage. It's neither fish nor fowl...
...medium isotopes not so far, the heavy "grapefruit" isotopes, a still shorter distance. By measuring the distances between them on the plate Dr. Bainbridge could calculate the relative weights of Ne20, Ne21, and Ne22. He thinks he can do the same for many another isotope of many another element, including the isotope of hydrogen, found last December (TIME, Dec. 21). By weighing the hydrogen isotope he thinks he may be able to throw some light on what happens to .0308 of hydrogen's atomic weight (1.0077) when four atoms of it combine to form one atom of helium (atomic weight...
...over ten years Leverett become more and more popular," said Professor Morison, "and seen the leader of the liberal element at Harvard. He and his supporters were opposed by licensee Mather 1606 then rector (president) of the University. This bitter struggle between the conservative and liberal causes, which involved particularly the fields of theology and education, spread all over New England. Leverett finally left Harvard, and within a few years became a justice of the Supreme Court of Massachusetts...
...current of electricity into the magnets. Their opposite fields wrench the light beam. The twisting follows the throwing of the switch by a time interval which must be measured in billionths of a second. Because that infinitesimal measurement is possible and because the time lag is different for every element and every form of every element, it is a delicate analyzer of unknown substances. It can discern one trillionth of a part of a foreign substance in anything presented to its wrenching beam. Last week's triumph of Professor Allison was his ability to state that eka-cesium...
