...become an elaborate science using small, costly, natural crystals like Iceland spar. Polaroid's sponsors say that it will do anything expensive crystals will, can be inexpensively manufactured in any size. Actual cost figures will probably not be available until large-scale equipment is set up. Developed by Physicist Edwin H. Land, senior partner of an independent Boston laboratory, Polaroid's synthetic organic crystals are bound in a plastic film of cellulose acetate. The tiny crystals are pulled into parallel alignment by stretching the film. The material polarizes about 99.9% of the transmitted light. Other uses for Physicist...
Their enthusiasm provoked Dr. Gertrude Siegmond Nielsen, 41, Norman, Okla. child specialist, wife of a University of Oklahoma physicist and mother of three, to pop up at an A. M. A. section meeting and cry: "Child bearing is so essential an experience for a woman that the thwarting of its normal course by the excessive use of analgesics may cause great damage to her personality. If she is carried through delivery in an unconscious state, she is deprived of the experience of giving birth to her child and in some cases will pay for this escape from reality by nervous...
Even with diamond-pointed ruling machines it is extremely difficult to rule hundreds of thousands of such infinitesimal lines accurately on hard metal or glass. Last week at the Washington meeting of the National Academy of Sciences (see above), Physicist Robert Williams Wood of Johns Hopkins showed how a brilliant scientist may adapt for his own use a technique worked out for a wholly differ ent purpose. At California Institute of Technology, Dr. John Donovan Strong has been coating telescope mirrors with a thin, even layer of aluminum by placing the glass in a vacuum tank, boiling the aluminum...
...Gorrie was a good enough physicist to know that expanding air absorbs heat from its surroundings. Accordingly he built a steam-driven pump which packed air to ten times atmospheric pressure. The released air chilled water until it froze. Dr. Gorrie was granted U. S. Patent...
...Princeton 500 well-behaved demonstrators gathered to hear a pacifist message from Physicist Albert Einstein, a speech by Columnist Dorothy Thompson Lewis who advised: "Go into politics, young men. There's plenty to do in this country, getting it back from the pioneers who nearly ruined...
