...this hypothesis can be found on all sides. On the side of the sun, for instance, there is an extraordinary abundance of both hydrogen and helium. What is more plausible than that the one should be created from the other? On the side of physics, there are no other nuclear changes which could take place, as far as science knows now, that would be powerful enough to produce the cosmic ray discovered by Dr. Millikan. On the side of philosophy, the tearing-down process of radio activity represented by the disintegration of heavy atoms into lighter ones, has been known...
...nucleus with a positive charge of electricity and one or more electrons with negative charges. The electrons (they are all the same size no matter what the element) revolve around their nucleus in a symmetrical pattern. Hydrogen, lightest of elements, has only one electron whirling around its nuclear "sun." Heavy metals, like lead, radium and uranium, have many electrons. In some elements some of the electrons pop away from their atoms. Such elements are radioactive. X-rays can make them pop away violently. When x-rays act so, Professor Compton learned, their wave lengths, thousand millionths of an inch long...
From this data it is apparent that the nuclear group of 500 eaters, declared to be essential to the success of any Common dining hall by the Comptroller's Office, can be recruited from a roving force of 6000. The Harvard Union has demonstrated that a University Dining hall based on voluntary attendance can succeed in spite of cafeteria competition. The Union attracts only a portion of the nomad horde; the majority wanders, at large inadequately and irregularly food...
