...Gamma chapter of Tau Beta Pi, the honorary society of the Engineering School, announced last night the election of six members of the Faculty of the School to its membership. The new members are Professors C. A. Adams, G. '92, H. E. Clifford '89, H. N. Davis, G. '02, L. J. Johnson '87, L. S. Marks, and Albert Sauveur...
Election of six members of the class of 1929, to the Gamma chapter of Tau Beta Pi, the honorary society of the Engineering School, was announced last night. Those to receive the honor are Grover Aruel Chenoweth '29, of Arlington; Frank Holton Elberfield '29, of South Boston; Malcolm Osborne Gibson '29, of Joplin, Missouri; Don Swint Greer '29, of Cambridge; Philip Ernest Nokes '29, of Boston; and George Alfred Sawin, Jr., '29, of Edgewood, Pennsylvania...
...nickel 1/2000 of an inch thin. (Human hair varies between 6/1000 and 126/10,000 of an inch in diameter.) And he used 350,000 volts of current. Electrons hurtled through the nickel foil, speeding about 150,000 miles a second (four-fifths the speed of light). As beta and gamma rays, similar to the offshoots from radium, they turned acetylene gas into a yellow powder such as scientists never before had seen. They made minerals fluoresce, killed bacteria and insects, burned a rabbit's ears (TIME...
Tandem Tubes. To get gamma rays to rush as fast from his tube as they do from radium, Dr. Coolidge would need about 2,000,000 volts of electricity. To get beta rays as penetrating as those from radium, he would need 3,000,000 volts. If he could create such voltages and if he could direct them properly, he would be, according to Philosopher Henri Bergson, at the heart of the world. Dr. Coolidge has succeeded in using 900,000 volts effectively. How he worked, he described to the engineers at Manhattan last week after receiving his latest medal...
