...hero, Lewis writes little of the spectacular deeds of heroism that usually fill such memoirs. He loved flying for its own sake-to get up above the clouds and stare at the "level plain of radiant whiteness, sparkling in the sun" when the unearthly light seemed to permeate every atom of air in the "dazzling, perfect basin of blue." Then he was as happy, he felt, as he could ever be. A rainbow at that height was not an arc but a perfect circle. He could dive and turn to watch the shadow of his plane on the clouds. Down...
Dangerous Molecule. Prime concern of physicists is the atom, of chemists the molecule. But whereas the batches of atoms created or transmuted by physicists cannot even be seen under the microscope, chemists now synthesize molecules after Nature's pattern in quantities that keep factories humming and salesmen humping. Molecules are groups of atoms which act as chemical units. The vast importance of molecular structure is well illustrated by the case of ozone, which is a modification of oxygen having three atoms in its molecule instead of the ordinary two. In the popular mind "ozone" has long been a synonym...
...Paris delivered an important paper on "The Extension of Tensor Analysis to Non-Affine Geometries." Speaking in French, bouncing with animation, gesturing with vehemence, this tanned, fox-bearded little man suggested a new mathematical approach to the great problem of a unified field theory which would embrace both the atom and the universe-a theory for which Professor Einstein has long been the No. i searcher. Roughly speaking, "non-affine" space is undistorted space. Dr. Cartan finds that some of the "vectors" with which Relativists play have a dual existence-in distorted Einstein space and in undistorted Euclidean space. These...
...substituted for "Hello" as a telephone salutation, life insurance be abolished. Father Divine habitually ends his letters: "This leaves ME Well, Healthy, Joyful, Peaceful, Lively, Loving, Successful, Prosperous and Happy in Spirit, Body and Mind and in every organ, muscle, sinew, vein and bone and even in every atom, fiber and cell of MY bodily form...
Neutrons have about the same mass as the heart of a hydrogen atom, but they are much smaller. Dr. George Braxton Pegram and his associates at Columbia have set the neutron diameter at one ten-trillionth of an inch. Unlike electrons, positrons, protons and deuterons, neutrons have no electric charge. Hence they make splendid projectiles for bombardment since they are not repelled by the positive charges on the atomic nuclei. Alpha particles knock neutrons in quantity out of beryllium and other light elements at speeds up to 30,000 miles per second. When the neutron hits a nucleus it either...
