...thyroid enlargement. To the thyroid function cheery Dr. Crile has tried to apply his electronic theory of life (TIME, Dec. 5. et ante), a theory to which his colleagues listen with aseptic indulgence. Said Dr. Crile in Memphis: "What we eat is radiation. Our food is so much quanta of energy, not in that inert word calories, but quanta. The sun shines upon our food products, and the sun shines secondarily within us. in the body's protoplasm. Energy contained in food is put there by the sun's radiation on the atoms of plants. Atoms...
...alpha particles, and they have great penetrating powers. They can travel through a mile of air, several feet of lead. They apparently weigh 200,000,000,000,000,000,000,000 to the ounce. It is only by the finest of discernment that they can be distinguished from unentangled quanta of energy. Streams of them may be what Dr. Robert Andrews Millikan calls cosmic rays. But Dr. Chadwick doubts that. Neutrons may be, because they have opposite poles, the long sought units of magnetism. Whatever they are, neutrons are fine things for physicists to play with and to guess about...
...many, General Smuts's scientific philosophy is comfortingly anthropocentric. The universe of 20th Century physics he accepts completely. It is for him a stupendous organization of atoms, electrons, protons, radiations and quanta. From this "uncertain nebulous underworld, there seems to crystallize out, or literally to materialize, the macroscopic world. . . . We rise to new levels as later on we pass from the physical to the biological level, and again from the latter to the conscious mind. But-and this is the significant fact-all these levels are genetically related and form an evolutionary series; and underlying the differences...
Light is a stream of particles, which may be called quanta or photons. Each particle twirls as it moves away from its source...
...Nature's great book is written in mathematical language.' So true is it that no one except a mathematician need ever hope fully to understand those branches of science which try to un ravel universe-the theory fundamental of nature of relativity, the the theory of quanta and the wave-mechanics...
