...tests involving 32 different strains of bacteria, Cornell University Biologist Martin Alexander and General Electric Chemist John Gould have found that each excretes metabolic wastes that are chemically distinct. When the waste products of a single strain are passed through a laboratory chromatograph. a device that separates chemical compounds, they produce a distinctive graph with characteristic peaks and valleys. Thus the graphs or chromatograms of unidentified bacteria can be com pared with those of known bacteria and-like fingerprints-be used to establish their exact identity...
...drug was developed in 1938 by Dr. Albert Hofmann, a research chemist at the Sandoz laboratories at Basel, Switzerland, who was trying to find a new stimulant for the nervous system. He did not know what he had done, however, until five years later, when he accidentally inhaled a minute amount and became dizzy and delirious, with "fantastic visions of extraordinary vividness accompanied by a kaleidoscopic play of intense coloration...
...also honored three prominent scientists: John Rock '15, Clinical Professor of Gynecology, Emeritus and a pioneer in birth control (LL.D.); John H. Van Vleck, former dean of the Division of Engineering and Applied Physics and a forerunner in discoveries in quantum theory, who received a Doctor of Science; and chemist Manfred Eigen, division director at Max Planck Institute for Physical Chemistry at Goettingen, Germany, a pioneer in perfecting techniques to measure chemical reactions to a minute fraction of a second, who also received a Doctor of Science...
Fascinated by the color theories of the French chemist, Michel Eugène Chevreul, La Farge searched along the same lines that the impressionists were to follow. He wrote: "I wished to apply principles of light and color of which I had learned a little. I wished my studies of nature to indicate very carefully, in every part, the exact time of day and circumstance of light." It was the same route that Monet, slightly his junior in age, was to follow to perfection. In practice, La Farge is more similar to that French loner, Puvis de Chavannes, who also...
...effort to clear up the confusion, Kuppermann and Chemist John White have taken an impressive step toward making chemistry exact and predictable: they have made the first direct measurement of the minimum energy required to cause one of the simplest chemical reactions known to science. An absolute minimum of one-third of an electron volt is needed, they discovered, to split a hydrogen molecule into two hydrogen atoms and to combine one of them with a deuterium atom to form deuterium hydride. An addition of any less energy and the reaction will not occur...
