Medieval man knew of only four elements-earth, air, fire and water. By 1940, scientists knew of 92 elements-ranging from lightweight hydrogen, whose atom has only one electron, to heavy uranium, with 92 electrons. Many chemists thought that their long search for elements was ended, and then the University of California's powerful cyclotron got busy...
...laymen "h" (Planck's constant) is a tiny number (.000 000 000 000 000 000 000 000 006 6 . . .), but it shook the scientific world. The little quanta of energy are the building stones of the universe, far more fundamental than big, clumsy atoms or even protons or electrons. Out of their discovery grew Einstein's relativity, including his historic proof, not then considered fraught with danger to civilization, that matter is equivalent to energy. Out of it grew Niels Bohr's description of the atom as a sort of sun surrounded by electron planets which jump...
...electrically charged particle from outer space) approaches the earth, it is deflected by the earth's magnetic field. If it is speeding fast enough, it slams through this interference and plunges into the atmosphere. The most powerful particles, whose speed gives them an energy of 14 billion electron-volts, can reach the earth at the equator, where the magnetism is strongest. At the latitude of Philadelphia, two billion volts is enough...
...learn the molecular inwardness of the matter, the kinetic mechanism with all its defects serving as a ladder toward specific experimental inquiry. He is not so crude as to look for a nexus of springs pulling dashpots through baths of hydraulic oil when he peers at muscle fibers in electron microscope pictures, though this kind of model has had brilliant uses for some purposes. On the other hand he knows in a practical way, as the logician knows, that reasoning by analogy from dynamical properties of the model is liable to stumble over imperfections in the analogy...
...hospital is the first unit in the $8,500,000 cancer center which will be completed in 1951. The second unit will be the Atomic Energy Commission's Argonne Cancer Research Hospital. Also under construction are a $2,200,000 synchrocyclotron and a 400-million electron-volt cyclotron in the new Accelerator Building. The complete project will be the first university center devoted exclusively to the study of cancer...
