Knowing well that the poll tax is the chief device whereby Southern Democrats prevent Negroes from voting, the wariest politician in the U.S. quickly added that in condemning the poll tax he was not talking about Negroes. They, he said, were a problem to be handled separately. At this remark, political ears pricked.

Main approach to the problem of utilization of solar energy has been study of green plants, which in their own simple and mysterious way utilize the energy of sunlight to convert carbon dioxide and water into food. Chief agent in this process of photosynthesis is chlorophyll, the green coloring-matter in leaves, which acts as a catalyst, speeding up the transformation, but undergoing no conversion itself. Since chlorophyll is not effective as a catalyst when extracted from the plant, chemists have been unable to study its action. It is composed of two separate pigments, blue-green chlorophyll A and yellow...

Harmonic analysis is that branch of mathematics concerned with the study of fluctuating or oscillating motions. Ever since the 18th Century mathematicians have occupied themselves with the hypothetical case of an infinite piece of string. In how many ways could such a string vibrate? Today the problem has taken a more practical turn. Mathematicians want to separate complex waves and oscillations into simpler movements. Chief use for harmonic analysis is study of the problems presented by the whirls and eddies of air around airplane wings. For example, harmonic analysis makes it possible to measure the varying speed at different points...
...framework of his philosophy is simple: Man, he says, is a product of his environment, and environment is "95% a shelter problem."
