Extractions: from GE Review , December 1932. "The causes which have made it necessary to operate tungsten lamps at such relatively low efficiencies as one watt per candle have been little understood. It seemed, therefore, that an investigation of the phenomena occurring in tungsten lamps, carried out with a view of reaching a clear understanding of the causes of the failure of the lamps, might possibly open the way to the discovery of methods by which the efficiency could be greatly improved." October 1913. Irving Langmuir received a Ph.D. in physical chemistry in 1906 from the University of Göttingen. He studied under Walther Nernst who had invented a new type of incandescent lamp only a few years before. After graduating, Langmuir took a teaching position at the Stevens Institute of Technology but left in 1909 to accept a position at the General Electric Research Lab. Ironically, he soon invented a lamp that made the Nernst Lamp (among others) obsolete. In 1910 Langmuir began to experiment with bendable tungsten wire developed by his colleague William Coolidge. Langmuir's goal was to find a way to keep tungsten lamps from "blackening," or growing dim as the inside of the bulb became coated with evaporated tungsten. Though his work did not solve this problem it did result in a coiled tungsten filament mounted in a gas-filled lamp the same design still used today.

Extractions: The specific project was conducted by Dr. Irving Langmuir's research group (including Dr. Bernard Vonnegut) at the General Electric Company, under contract to the U.S. Military. As part of this project, Dr. Vonnegut released AgI from a generator on the ground at Socorro, NM on Tuesday, Wednesday, and Thursday of each week during 6 Nov 1949 to 27 April 1950. (Langmuir's Collected Works, Vol. 11, p. 217) Langmuir claimed that this release of AgI modified the weather, not only in the state of New Mexico, but also more than 1000 kilometers downwind. Langmuir's evidence was a seven-day periodicity found in meteorological records in the Ohio River Valley, the Wabash River Valley, as well as in New England. Annotated Bibliography Langmuir made a few public presentations of his claims at meetings of various scientific societies, and brief versions of his claims were published at:

Extractions: Cientista norte-americano nascido em Brooklyn, Nova Iorque, a 31 de Janeiro de 1881 e falecido no Massachussets a 16 de Agosto de 1957. Estudou na Universidade de Columbia, dedicando-se à investigação na General Electric Co. entre 1909 e 1950. Dedicou um interesse especial à Quimica das superfícies, formulando o princípio da acção superficial, que lhe mereceu o Prémio Nobel da Química em 1932. Inventou as lâmpadas eléctricas em atmosfera gasosa, mediu a temperatura de fusão dos sólidos refractários e descobriu o hidrogénio atómico. Como resultado das suas investigações sobre a cinética das reacções gasosas e em especial sobre a velocidade de adsorção das moléculas dos gases a baixas pressões, deduziu a isotérmica de adsorção a que foi dado o seu nome. Ocupou-se ainda da produção de chuva artificial (1946).

Born January 31 in Brooklyn, New York - Died August 16 in Woods Hole, Massachusetts He graduated with a B.S. from the Columbia University School of Mines in 1903 and did postgraduate work in chemistry under Nobel laureate Walther Nernst in Göttingen and earned his Ph.D. degree in 1906. Langmuir then taught at Stevens Institute of Technology[?] in Hoboken, New Jersey , until 1909, when he began working at the General Electric research laboratory ( Schenectady, New York ). While at G.E., from 1909-1950, Langmuir advanced several basic fields of physics and chemistry , invented the gas filled incandescent lamp, the hydrogen welding technique, and was awarded the 1932 Nobel Prize for Chemistry for his work in surface chemistry His initial contributions to science came from his study of light bulbs (which was a continuation of his Ph.D. work). First his improvement of vacuum techniques led to the invention of the high- vacuum tube . A year later he discovered that the lifetime of a tungsten filament was greatly lengthened by filling the bulb with an inert gas, such as

Extractions: Click to order from Amazon "Pathological science" is a term coined by Nobel-laureate in chemistry Irving Langmuir in a presentation he made at General Electric's Knolls Atomic Power Laboratory a few years before his death in 1957. Langmuir described typical cases as involving such things as barely detectable causal agents observed near the threshold of sensation which are nevertheless asserted to have been detected with great accuracy. The supporters offer fantastic theories that are contrary to experience and meet criticisms with ad hoc excuses. And, most telling, only supporters can reproduce the results. Critics can't duplicate the experiments. He gave several examples, including ESP experiments and Blondlot's N-rays , and stated that These are cases where there is no dishonesty involved but where people are tricked into false results by a lack of understanding about what human beings can do to themselves in the way of being led astray by subjective effects, wishful thinking or threshold interactions. These are examples of pathological science. These are things that attracted a great deal of attention. Usually hundreds of papers have been published on them. Sometimes they have lasted for 15 or 20 years and then gradually have died away. Langumuir visited J.B. Rhine's lab at Duke University where Rhine was claiming results of ESP experiments that could not be predicted by chance and were probably due to some sort of psychic power. Langmuir found that Rhine was not counting all his data, however. He was leaving out the scores of those he believed were guessing their
