When a piece of iron or other substance is magnetized, the molecules yank one way. When the substance is demagnetized the molecules jerk helter-skelter. The magnetic yanking causes molecular friction and produces an appreciable amount of heat which Professor Wrilliam F. Giauque, University of California chemist, used last week to reach the lowest degree of cold yet attained...
...noticed that an extremely bright, fiery thread extended backward from the main mass before it spread out into the gaseous brilliantly shaded tail, which may have been between 50 and 100 miles long." One million meteors enter the earth's atmosphere each hour, become incandescent from friction. But rarely are astronomers able to photograph the hot spots and analyze the spectra. Last week Harvard's Dr. Peter Mackenzie Millman proudly reported that he had spectral pictures of nine meteors. Six, possibly seven were mostly stone. All contained some iron (heated to vapors of between...
...burly, booming old Captain Robert Abram ("Bob") Bartlett, who while visiting Alaska is acting correspondent for the New York Times. Dr. Maris expounded: "The earth in its motion through space occasionally passes through streams of gas, debris of comets, etc. It is entirely within the realms of possibility that friction between the atmosphere of the earth and these very rare gas clouds should leave the earth with a positive charge...
...difficult to get all the facts underlying the drastic action taken by the faculty in one case and the student council in the other. But it seems plain enough that the subsequent situations were both handled with complete lack of tack, and in a way calculated to promote friction. When five hundred students of City College attempted to present a petition to their president, they were refused admittance. No effort was or has been made to settle the matter in a sensible manner with some regard for the feeling of the undergraduates. To deny them the privillege of petition...
...Spanish and French were attempting to crush the Riffs. In 1923 the Italians bombarded Corfu. In 1929 the Chinese and Russians saw action in Manchuria. For the last few years Japan has been grappling with China in the same region; while in South America there has been continual friction. At the present moment Bolivia and Paraguay are in opposite trenches, Peru and Colombia began offensive operations, yesterday. All these minor wars, plus the Big Blow of 1914-1918, are well within the twenty years of progress mentioned by President Hoover...
