...faculty of Washington University at St. Louis. Recently at a convention of scientists in Indianapolis, Dr. Jauncey described experiments which convinced him that the rest-masses of beta rays (fast electrons) shooting out of Radium E were variable (TIME, Jan. 17). He passed his electrons through a velocity selector, then estimated their masses by their behavior in electrical and magnetic fields. Since then Dr. Jauncey has bombarded the Physical Review with numerous communications backing up his announcement, has reproduced a film on which electrons apparently of varying mass made divergent tracks...
...Jauncey cudgeled his brain for some way to verify experimentally the variable mass of electrons. On December 18 he hit on the idea of passing the electrons from Radium E through a velocity selector, then into a magnetic field. If the particles, selected for uniform velocity, were also of uniform mass, they should be uniformly curved by the field and would strike a photographic film in the same place. By that time the physics department at Washington University was so excited that Jauncey was offered the run of the laboratory and all the help he wanted. He stayed...
...Selector for Book Digest is Donald Leonard Gordon, long a consulting expert to the book trade. Mr. Black's book career began in 1923 when he was salesman for a company publishing a one-volume Shakespeare. Launching out for himself on a $500 stake, Bookseller Black became Publisher Black with a one-volume Shakespeare of his own. Since then, Publisher Black has issued over 70 "classics," spent upwards of $1,000,000 advertising them...
...happens after his return from the men's room is a four-cornered chase. Oiwin is trying to write 67 Mother's Day greeting-card orders for delivery to his employer, Mr. Carver (Guy Kibbee), Charlie, Patsy and Frankie are trying to capitalize Oiwin as a race-selector. Mr. Carver is combating the horse-players, whom he mistakes for a rival greeting-card combine, and Oiwin's wife, in Ozone Heights, is getting the police to find her husband...
...before them. The scene was not a highway but the psychological laboratory of Massachusetts State College at Amherst, or the 1935 Boston automobile show, or the 1934 Eastern States Exposition at Springfield, Mass. When the person being tested put his foot on the accelerator, the cam of a motor selector switch was set revolving, turning the green light to amber in two seconds. Thereafter, at an unpredictable interval, the amber light turned red. As soon as he saw the red light the subject removed his foot from the accelerator, applied the brake. The time interval was electrically measured. The average...
