...radio fans of the Island Empire " listened in " on their radio sets to a polysyllabic discourse on " why inexhaustible light and power can never be provided by the harnessed energy of the elusive atom." Great was the uproar next day from thousands of radioites. " Why did you do it ?" the director of the broadcasting programs was asked. His answer was as abstruse as the subject that prompted the question. Henceforth the radio fans are eager to receive jazz. (For a scientific account of this speech, see page...
...clock tonight in the large lecture room of the Jefferson Physical Laboratory, Dr. E. C. Kemble, G. '14, will give the second of a series of three lectures on Physics, taking for his subject, "Atomic Explosions". This particular phase of Physics has been chosen on account of the wide interest taken by the public in the recent important discoveries which have thrown light on the composition and behavior of the atom. Dr. Kemble is well fitted to discuss the subject, having done much advanced research work in this field...
...matter is made up of "electrons," particles of negative electricity, and "protons," particles of positive electricity. The smallness of the electron is beyond human comprehension. Its diameter is about 30 trillionths of an inch. The most powerful microscope known would barely enable us to see an object 200 atoms wide, and if an atom were about the size of a large office building, an electron would be the size of a pinhead. Professor Thomson was Cavendish professor of experimental physics in Cambridge University from 1884 un- til 1918. During that time he developed a great research laboratory which attracted workers...
Professor Sommerfeld first described the Rutherford idea of the structure of the atom following which he compared the atom to the stellar and solar system. He pointed out that, in general, material that is amassed is qualitative rather than quantitative except in the cases of hydrogen and helium...
...consider "Science 1"; ultimately it would probably cover, under the general topic "the structure of matter", the electron, the atom, the molecule, and all the various phenomena that are classified under such heads. And in addition it would point out the relationship between these phenomena and the phenomena of astronomy. "Science 2" would be concerned essentially with evolution, both of organic and inorganic substances. These are fields of so great importance and such large scope that the course could easily include as well the main principles of botany and zoology...
