...principal reason for the belittling of this rumor was the ease with which radio waves, short enough to transmit sufficient power to effect a magneto, could be shielded. These waves are of optical range, that is to say, their power of penetration is little better than that of light. This means that the hood of a car would be more than sufficient to render them impotent...
...first describes an early trans-continental flight to Australia, and it illustrates abundantly the devotion of Day Lewis to a strictly contemporary poetic diction, which takes account of the machine and the effect of machinery upon modern life. There is mention, for example, of 'petrol pump,' 'hangar,' 'filter,' 'magneto,' and other technical expressions. Dr. Johnson's strictures on this kind of poetic diction appear in his discussion of Dryden's "Annus Mirabilis," and though they posses a universal validity, they do not apply, with any exactness, to Day Lewis, for that poet has worked them into his verses in such...
...case of tritium, triple-weight hydrogen, is different. Its discovery was foreshadowed by the somewhat dubious magneto-optic method which anticipated the identification of deuterium. Then, in England, Lord Rutherford bounced deutons (deuterium nuclei) together, got protons and something of mass three which he thought was either an unknown form of helium or triple-weight hydrogen. Cautious Lord Rutherford took his time ascertaining that the new particles were both helium and tritium. Meantime Dr. Merle Antony Tuve and his associates at the Carnegie Institution of Washington had identified tritium particles by measuring their mass as indicated by the curvature...
...more isotopes of its own. Birge of the University of California and Menzel of Harvard showed that the difference would be erased if one atom of hydrogen in every 4,500 had a nucleus twice the weight of the common nuclei. Allison of Alabama Polytechnic Institute found some curious magneto-optic effects in hydrogen which he chose to explain by the presence of a double-weight isotope...
...there has been talk of a third isotope of hydrogen whose atomic weight should be approximately 3 as against deuterium's 2 and hydrogen's 1. Two members of Dean Lewis's staff reported finding it last autumn (TIME, Nov. 20). But they used the same magneto-optic method by which Professor Allison predicted deuterium, and among scientists the worth of this procedure is debatable. In England Lord Rutherford (who calls deuterium diplogen and its nucleus the diplon) bounced deutons against deutons. Each collision produced a proton and something new of atomic weight 3. But cautious Lord...
