General Science History
In 1871, the American Museum of Natural History opened to the public in New York City. With a series of exhibits, the Museum’s collection Went on view for the first time in the Central Park Arsenal, the Museum’s original home, on the eastern side of Central Park. The museum began from the efforts of Albert Smith Bickmore, one-time student of Harvard zoologist Louis Agassiz, who was successful in his proposal to create a natural history museum in Central Park, New York City, with the support of William E. Dodge, Jr., Theodore Roosevelt, Sr., Joseph Choate, and J. Pierpont Morgan. The Governor of New York, John Thompson Hoffman, signed a bill officially creating the American Museum of Natural History on 6 Apr 1869.
In 1878, Louis Pasteur lectured at the French Academy of Science in support of his germ theory of disease, in which he held that many diseases were caused by tiny organisms. Since he still met with opposition from some scientists, he called their contrary opinions “fatal to medical progress.” Pasteur also described ways to prevent infection, and provided the skeptics with an experiment with which to prove the theory to themselves.
In 1955, the element 101, a new artificial element was announced. It was synthesized by bombardment of Es-253 with helium nuclei using the cyclotron at the Radiation Laboratory of the University of California by Albert Ghiorso, Bernard G. Harvey, G.R. Choppin and S.G. Thompson, research chemists, headed by the Nobel laureate Glenn T. Seaborg. Being radioactive, with a half-life of between a half hour to several hours, this transuranic element cannot exist in nature since it decays so rapidly into lighter elements. It was named mendelevium, named in honor of Dmitry Mendeleev, the Russian chemist who worked on the periodic classification of the elements.
In 1926, the term “wave mechanics” was coined by nuclear physicist Erwin Schrödinger in a letter he sent to Albert Einstein. The term was applied to the newly emerging branch of physics which interprets the behaviors of subatomic particles according to a mathematical description in terms of a wave motion.
In 1930, the first U.S. motion picture of the 1.5 minute totality of an eclipse of the sun was taken from an airplane flying about 18,000 feet over at Honey Lake, California. The flight was sponsored by the U.S. Naval Observatory, and carried out by Lt. Leslie E. Gehres amd Chief Photographer J.M.F. Haase of the U.S. Navy. An attempt made during an earlier eclipse had been made by the same photographer on 10 Sep 1923, but was unsuccessful due to cloudy conditions. A U.S. Navy dirigible was first used to make a motion film of an eclipse on 24 Jan 1925. The dirigible was about 4,500 feet above a point almost 19 miles east of Monauk Point, New York, which it filmed the 2-min 5-sec eclipse.
