Henry A. Bumstead

Henry A. Bumstead Henry Andrews Bumstead (March 12, 1870 – December 31, 1920) was an American physicist and professor at Yale University. He was elected in 1913 to the U.S. National Academy of Sciences, in 1914 to the American Academy of Arts and Sciences, and in 1918 to the American Philosophical Society. Quotes ... I believe that engaging in research is the best way and the only certain way for a teacher to keep himself alive intellectually and to retain his spirit and enthusiasm to the end. And even if the college he serves regards teaching and not research as its chief business, even then, I contend, he must be given a reasonable amount of time and reasonable opportunities for research in order that he may keep his intellectural health, just as he is given time for physical exercise in order that he may maintain his bodily health. The Functions of a University Laboratory Science 31 793 March 11, 1910 361–370 10.1126/science.31.793.361 quote from p. 370 Chapter II. Physics in The Development of the Sciences (1923) For some unknown psychological reason, the appreciation of the possibilities of experiment as an intellectual tool and the ability to make use of its technique appear very late in the history of human development. A few individuals like Archimedes understood and practiced it, and it is difficult to understand why the seed which they sowed proved sterile. Chapter II. Physics "'The Development of the Sciences'' 43–73 1923 6 chapters from 6 different lectures delivered in 1920 at Yale University by Ernest William Brown, Henry Andrews Bumstead, John Johnston, Frank Schlesinger, Herbert Ernest Gregory, & Lorande Loss Woodruff Yale University Press https://books.google.com/books?id=xNi4AAAAIAAJ&pg=PA43 (327 pages; edited by Lorande Loss Woodruff; quote from pp. 43–44) In the eighteenth century the development of mechanics and of History of gravitational theory gravitational theory was carried on by the three Bernoullis, Euler, Alexis Clairaut Clairaut, d'Alembert, and others. This development reached its culmination near the end of the century in the publication of Lagrange's Mécanique_analytique ’’Mécanique Analytique’’ and of the Traité_de_mécanique_céleste ’’Mécanique Céleste’’ of Laplace—works which for completeness and finish have seldom, if ever, been excelled. p. 50 During the eighteenth century the experimental knowledge of both electricity and magnetism progressed rapidly. The conduction of the electrified state by metals was discovered by Stephen Gray (scientist) Stephen Gray; the Leyden jar was invented; Charles_François_de_Cisternay_du_Fay du Fay found that there existed two opposite states of electrification which he called vitreous and resinous and that these behaved, as to attractions and repulsions, like the two poles of a magnet. America made her first contribution to physics in the very important work of Benjamin Franklin. pp. 51–52 External links Category:1870 births Category:1920 deaths Category:Academics from the United States Category:Fellows of the American Academy of Arts and Sciences Category:Johns Hopkins University alumni Category:Members of the American Philosophical Society Category:Members of the United States National Academy of Sciences Category:People from Illinois Category:Physicists from the United States Category:Yale University alumni Category:Yale University faculty
