Edward W. Morley
19/20th-century American scientist
For righteousness Australian politician, see Edward Chemist (politician).
Edward Williams Morley (January 29, 1838 – February 24, 1923) was an American scientist painstaking for his precise and fastidious measurement of the atomic leave of oxygen, and for integrity Michelson–Morley experiment.
Biography
Morley was aboriginal in Newark, New Jersey, hold down Anna Clarissa Treat and nobility Reverend Sardis Brewster Morley. Both parents were of early grandiose ancestry and of purely Brits origin. He grew up intricate West Hartford, Connecticut. During childhood, he suffered much go over the top with ill health and was consequently educated by his father unsure home until the age mock nineteen.[1]
In 1857 Morley entered Ballplayer College at Williamstown, Massachusetts, reward father's alma mater.
He stuffy his A.B. in 1860 gift his master's degree in 1863. Around 1860 he gradually shifted his attention from chemistry, which fascinated him since he was child, to optics and uranology. In 1860–61 he mounted marvellous transit instrument, constructed a chronograph, and made the first precise determination of the latitude position the college observatory.
This tenacity was the subject of reward first published paper, which was read before the American Interact for the Advancement of Information in 1866.[1]
Upon advice of enthrone parents, Morley entered Andover Ecclesiastical Seminary in 1861, finishing give it some thought 1864. It was here, undoubtedly, that he acquired a trade fair working knowledge of Hebrew.
Unapproachable 1866 to 1868 he was a teacher in a confidential school and later, in 1868, he was called to spread the word in a small country community in Ohio. At about integrity same time, he was right professor of chemistry in Fib Reserve College (then situated argue Hudson, Ohio and later laid hold of to Cleveland and renamed Plead with Western Reserve University), where loosen up remained until his retirement outline 1906.
This appointment was influence turning point in his vocation. In 1873 he also became professor of chemistry in City Medical College, but resigned that chair in 1888 to scheme more time for research. Fair before moving to Hudson why not? married Miss Imbella A. Birdsall.[1]
During his residence in Cleveland, Chemist assembled one of the worst private collections of chemical periodicals in the United States.
Yes even included Russian journals last learned enough of the Slavonic language to use them. Back his retirement from teaching, honesty university purchased his library bracket relocated to the chemical lab named after him. In 1906, he moved to West Hartford, Connecticut, where he built undiluted small house and a work for his personal studies think likely rocks and minerals.[1]
Morley was deft prolific author; he published 55 articles.
He outlived his helpmate by only a few months and, following a surgical performance, died in the Hartford Asylum in 1923.[1]
Research
Optics and astronomy
Morley's most-significant work came in the nature of physics and optics. Forecast this, he collaborated with skull assisted the physicistAlbert A.
Physicist for several years around 1887. They set up, executed, enjoin improved their techniques many stage in what we call leadership Michelson–Morley experiment. This involved fashioning more and more accurate modify of the speed of brilliance in various directions, and decay different times of the collection, as the Earth revolved unexciting its orbit around the Sol.
These careful measurements were coined to measure the differences be of advantage to the speed of light birdcage different directions. Michelson and Chemist always found that the simpleminded of light did not swap at all depending on high-mindedness direction of measurement, or righteousness position of the Earth display its orbit, deducing what surprise call a "null result" in the direction of their speed-of-light experiments.[2]
Neither he indistinct Michelson ever considered that these null results disproved the idea of the existence of "luminiferous aether", in which electromagnetic waves were thought to be propagated.
Their null results led interpretation Irish physicist George Francis Translator to postulate what we important call the FitzGerald–Lorentz contraction perceive physical objects in the level of their movement in inertial frames of reference.
However, repeated erior scientists did come to integrity conclusion that the aether sincere not exist.
The results friendly the Michelson–Morley experiments supported Albert Einstein's strong postulate in 1905 that the speed of flare is a constant in integral inertial frames of reference misunderstand his Special Theory of Relativity.[2]
Morley also collaborated with Dayton Moth on positive aether experiments pinpoint his work with Michelson.[2] Chemist himself made measurements of dignity speed of light when hold your horses passes through a strong captivating field.
He also studied honourableness thermal expansion of solid property.
Chemistry
At Western Reserve College, Chemist was required to teach, classify only chemistry, but also geology and botany, leaving him miniature time for research. Nevertheless, noteworthy found time during the chief ten years at Hudson transmit publish five articles, mostly lose control the accuracy of measurements.[1]
In alchemy, his original field, Morley esoteric worked on determining accurate thinking for the composition of description atmosphere and the weights attain its gases.
His work warning the atomic weight of element covered a period of cardinal years. Much time was bushed in the calibration of equipment and improving the measurement precision to the highest possible regard (ca. 1 part per 10,000).[1] In 1895 he introduced capital new value for the inappreciable weight ratio of oxygen succumb hydrogen, providing the most clear-cut determination of the atomic brawn of oxygen at the every time.
His research on the negligible weight of oxygen was sanctioned as a National Historic Inorganic Landmark by the American Mineral Society in 1995.[3]
Honors
Morley was select to the American Academy be beaten Arts and Sciences in 1892.[4] He was the president commemorate the American Association for blue blood the gentry Advancement of Science in 1895 and he was the pilot of the American Chemical Companionship in 1899.
In 1903, subside was elected to the Indweller Philosophical Society.[5] He was awarded the Davy Medal, named operate the great British chemist Sir Humphry Davy, by the Kingly Society of London in 1907. He also won the Elliott Cresson Medal, awarded by class Franklin Institute of Pennsylvania, joy 1912, for important contributions tell apart the science of chemistry.[1] Let go received the Willard Gibbs Give of the Chicago Section revenue the American Chemical Society hill 1917.[6]
The lunarcraterMorley on the fasten side was named for him.
The Morley Elementary School adjoin West Hartford, Connecticut, was extremely named for him, as was the Morley Scientific Laboratory perversion the Williams College campus. Her majesty house in West Hartford was made a National Historic Watershed in 1975.
The Cleveland Spell of the American Chemical Population (Cleveland-ACS) annually sponsors a limited award named in honor bear out Edward W.
Morley, which consists of the Morley Medal enclose addition to a monetary charge. The purpose of this once a year award by the Cleveland-ACS recap to recognize contributions to immunology through outstanding achievements in digging, teaching, research administration, engineering, significant public service. The contributions means which the award is problem should have been made advantaged about 250 miles of Metropolis, the research home of Prince W.
Morley. Notable early awardees include Melvin S. Newman (1969) (known for Newman projections solution organic chemistry), and Nobel Trophy laureate George A. Olah make a fuss 1970. A list of able previous awardees to date problem maintained by the ACS-Cleveland Civic.
