Words followed words. "Four dimension vector . . direct from Lorentz transformation . . . sum of impulses before and after collision . . . relative to all systems of coordinates. . . ." Sometimes the speaker lapsed into German, once or twice asked his hearers to translate a German technical word...
...Health to follow the lead of Dr. Kenneth Fuller Maxcy, who had left the Institute to become professor of public health and hygiene at the University of Virginia. Dr. Maxcy knew that U. S. inhabitants are seldom lousy, suspected that some other blood-sucking insect might be the vector of mild U. S. typhus. Dr. Dyer, who in his career had dealt with rat-borne bubonic plague, suspected rat fleas, proved his hypothesis correct-first on guinea pigs, next (by accident) on two assistants, Martin Joseph Mannix and Dr. Elmer Theodore Ceder, lastly upon himself. "Where," he demanded...
...appear to be responsible for the long preservation of the typhus virus in those limited districts. That agency, be it insect alone or an insect which feeds on some host other than man, must be correspondingly limited in its distribution. Or at least its capacity for acting as a vector to man must be so limited...
Talking Machines. When the cinema, café dancings, low-rate orchestra entertainments and radio decoyed people from the musical whirrings of their household phonographs, the Vector Talking Machine officials developed a new machine, the orthophonic; advertised so well that within two weeks of first announcement orders of $20,000,000 came in. People liked the machine, liked the prices. So the stockholders in meeting last week learned that their factory production-schedule the first quarter of this year was the highest in history, that their biggest business year lies before them...
...prize, for the most valuable contribution to science presented at the current meetings, was awarded to Dr. Leonard E. Dickson, Professor of Mathematics at the University of Chicago. His achievement was a general mathematical theory including as special cases certain fundamental branches, such as quaternions and vector analysis. It is comparable in importance to the so-called calculus of Ricci and Levi Civita, which formed the mathematical basis for Einstein's general relativity theory. Unfortunately, these theories are so abstruse that only the trained mathematician can penetrate their mysteries. Laymen must take on faith the fact that all branches...
