...London insurance corporation famed for willingness to write a policy on anything, upped its rates last week on insurance against twins. Reason for the upping, according to a Lloyd's spokesman, was Mrs. William H. Vanderbilt's recent success in finding out by means of X-ray that she would have twins- (TIME, Feb. 16). Hereafter Lloyd's will ensure against twins, triplets or other multiple births at the new high rate only if a policy is sought in earliest stages. "Much of our business of this character," said Lloyd's spokesman, "comes from the United...
...lengths of the radio waves used in ordinary U. S. broadcasting range between 200 and 547 metres. Short-wave broadcasting uses waves around 50 metres in length. Last week "micro" rays only 18 centimetres (7.09 in.) long carried two-way conversations across the English Channel. International Telephone & Telegraph Laboratories and Le Matériel Télephonique of France made the test. Simple equipment did the work. Sending and receiving devices were practically the same. Each device consisted of a vacuum tube which transformed telephone frequency into the high micro-ray frequency of 1,600,000,000 oscillations a second...
...strikes the moving figure will differ from the speed of the ball as it rebounds. By calculating with the two speeds it is possible to compute the merry-go-round's rate of revolution. What Caltech's du Mond and Kirkpatrick did was to shoot X-rays of known wavelength at the atoms of various elements. When an X-ray strikes an atom, the X-ray presumably hits and bounces off the orbital electrons, which are moving so fast that they give the effect of an impervious surface. The impact of the electrons alters the length...
Most active of the consulting physicians at present is Secretary of the Interior Ray Lyman Wilbur, M. D. Last week Dr. Wilbur was glad to announce that one of the giant's pains has been partially, temporarily, deadened. For Standard Oil Co. of Indiana finally agreed that for 90 days it will curtail its Venezuela production and imports by 23%. This compares to a 25% reduction by Royal Dutch-Shell. Although independent oilmen have wanted a total embargo or at least a tariff, this voluntary partial curtailment of imports was welcomed by them. Coming a week before the meeting...
...wished with electrons and protons. At that temperature matter's subunits dance around each other and coalesce as atoms; atoms break up into their electron and proton elements; and every explosion, every coalescence scatters atomic energy. Professor Compton cannot duplicate solar heat, but with a mighty X-ray tube, he calculates, he can drive particles of matter at speeds so nearly solar that new atoms will result. His tool will be a 10,000-volt tube, five times the size of the tube whose description won the American Association for the Advancement of Science's $1,000 prize...
