...sensitive, as interpretative as painting, etching or engraving. Out of the confused mass of forms in the visible world he selected serene or startling shapes and contours, the tense grace of sewing fingers, the slopes and rotundities of the nude. These he rendered with the infinite photographic spectrum, ranging from dead white to midnight blackness through numberless greys, catching both gleams and shadows. Sometimes he intellectualized this sensuous process, as in his symbolic expression of a short-skirted girl-a picture of a leg superimposed upon the dim image of a face. There is nothing documentary about Stieglitz photographs; they...
...motes, beams, the subtle tones of shadows. More than any other man, Monet epitomizes the impressionist movement, the realization that perceptual reality is not composed of insulated objects each of characteristic colors, but is rather a play of shapes at once defined and related by the one blazing spectrum...
...times greater than those emitted by the Cooper-Hewitt arc. Having measured the ray, Dr. Millikan sat down to figure out its importance. He turned to Einstein's theories. He found, using the Einstein equation (M C 2-E), that the most conspicuous band in the cosmic ray spectrum is probably the same band that would be formed by the monochromatic ether wave of the radiant energy which is liberated when hydrogen unites to form an atom of helium. Einstein's figure was reached by calculation: he reasoned that if 4 atoms of hydrogen united to form helium...
...Physicist Millikan directly observed the absorption coefficient of the most conspicuous band in the cosmic ray spectrum. It was within a few per cent .305. Things equal to the same thing being equal to each other, it seems that positive and negative electrons are daily uniting in the heavens to form helium and sending us a free cosmic ray as an announcement...
...veritable dynamo. The powerful magnetic field thus developed extends out into space and often disturbs radio, cable, and telegraph lines of the earth. Within recent years it has become possible to actually measure the field strength of these solar storms by means of a careful analysis of the spectrum of the sun spots...
