|| | ||1839: William 'Strata' Smith dies ... was an English geologist, credited with creating the first nationwide geological map. At the time his map was first published he was overlooked by the scientific community; his relatively humble education and family connections prevented him from mixing easily in learned society. Financially ruined, Smith spent time in debtors' prison. It was only late in his life that Smith received recognition for his accomplishments, and became known as the "Father of English Geology". Pic. | ||
|| | ||1845: The first issue of ''Scientific American'' magazine is published ... published by Rufus Porter (1792-1884), a versatile if eccentric Yankee, who was by turns a portrait-painter, schoolmaster, inventor and editor. While the paper was still a small weekly journal with a circulation less than 300, he offered it for sale. It was bought for $800 in July 1846 by 20-year-old Alfred Ely Beach (1826-1896) as editor, and Orson Desaix Munn (1824-1907). Together, they built it over the years into a great and unique periodical. Their circulation reached 10,000 by 1848, 20,000 by 1852, and 30,000 by 1853. Pic. | ||
||1850: First submarine cable laid: ''Goliath'' laid the cable between Dover and Cap Gris Nez in France on 28 August 1850. Unlike later submarine cables, this one had no armouring to protect it. The single copper wire was protected only by the layer of gutta-percha insulation around it. This made it very light, and it was necessary to attach periodic lead weights to make it sink. Messages sent across the cable were unintelligible due to dispersion of the signal, a phenomenon which was not understood at the time, and would be an even greater problem to the first transatlantic telegraph cable. Dispersion was a problem not fully solved on submarine cables until loading started to be used at the beginning of the 20th century. Both ends of the communication assumed that the messages did not make sense because the other end was in the midst of drunken celebrations of their success. It was decided to try again in the morning. During the night a French fishing boat accidentally pulled up the cable. Thinking the cable was a strange form of seaweed, the fisherman cut a piece out of it. He believed the metal inside was gold. The cable was never put back into service. https://en.wikipedia.org/wiki/Submarine_Telegraph_Company Pic. | |||
|| | ||1853: Vladimir Shukhov born ... architect and engineer, designed the Adziogol Lighthouse. | ||
|| | ||1863: Eilhard Mitscherlich dies ... chemist, who is perhaps best remembered today for his discovery of the phenomenon of isomorphism (crystallography) in 1819. | ||
|| | ||1863: André-Eugène Blondel born ... engineer and physicist. He is the inventor of the electromechanical oscillograph and a system of photometric units of measurement. Pic. | ||
|| | ||1867: Maxime Bôcher born ... mathematician who published about 100 papers on differential equations, series, and algebra. He also wrote elementary texts such as Trigonometry and Analytic Geometry. Bôcher's theorem, Bôcher's equation, and the Bôcher Memorial Prize are named after him. Pic. | ||
|| | ||1880: Charles Thomas Jackson dies ... physician, chemist, and pioneer geologist and mineralogist. Jackson's professional career consisted of a series of spectacular claims to the work of others which continued until he finally became insane in 1873. In 1832, during a voyage, he discussed with the portrait painter Samuel Morse the possibilities of electric telegraphy. Morse exhibited his telegraph to Congress in 1837 but had to spend seven years to establish a right to his own invention against Jackson's claim that Morse had stolen it from him. Jackson similarly claimed priority in the idea of use of ether as an anaesthetic, which he had suggested to a dentist, William Morton. Though the effects of ether were somewhat known at the time, it was Morton who made the idea practical. Pic. | ||
|| | ||1883: Jan Arnoldus Schouten born ... mathematician and Professor at the Delft University of Technology. He was an important contributor to the development of tensor calculus and Ricci calculus. Pic. | ||
||1892: Thomas Henry Moray born ... inventor from Salt Lake City, Utah. He received a US patent 2,460,707 in February 1949, after a process of 17 years in discussions with the patent office. The main components of the patent were an LC circuit resonator and a set of vacuum power tubes of diode type using uranium and radium power sources and doped germanium semiconductors on the cathodes. It was an early example of doped semiconductors and a forerunner of radioactive power supplies using radioactive isotopes in space research. Moray's device followed other work on nuclear batteries first done in 1913 by Henry Moseley using a radium source. | |||

||1940: William Bowie dies ... geodesist who investigated isostasy (a principle that dense crustal rocks to tend cause topographic depressions and light crustal rocks cause topographic elevations). He made measured gravity anomalies on land and obtained gravity surveys in the oceans. These observations correlated the anomalies with topographic features and validated the geological concept of isostasy. With John F. Hayford, his predecessor at the Coast and Geodetic Survey, he computed tables of the depth of isostatic compensation (the surface above which the weight of the crust per unit area is equalized). Bowie felt that this zone would occur at a uniform depth as predicted by John Henry Pratt, rather than at the varying depth predicted by Sir George Airy. He wrote Isostasy (1927). Pic. | |||
||1941: Peter Manfred Gruber born ... mathematician working in geometric number theory as well as in convex and discrete geometry. Pic. | |||
||1963: Julius Edgar Lilienfeld dies ... physicist and electronic engineer, credited with the first patents on the field-effect transistor (FET) (1925) and electrolytic capacitor (1931). Pic. | |||

||1993: Edward Palmer Thompson dies ... historian, writer, socialist and peace campaigner. Pic (megaphone). | |||
||1993: The asteroid 243 Ida became the first found to have a moon when it was visited by NASA's Galileo probe. The asteroid 243 Ida and its newly-discovered moon, Dactyl was imaged by NASA's Galileo spacecraft, about 14 minutes before its closest approach (within 2,400-km or 1,500 miles) to the asteroid. Ida is about 52 km (32 mi) in length and is irregularly shaped. It shows numerous craters, including many degraded craters, indicating Ida's surface is older than previously thought. Dactyl is only about 1.4-km in diameter, and it is spectrally different from Ida data. The picture was released on 26 Mar 1994. Galileo had encountered the first asteroid - 951 Gaspra - on 29 Oct 1991. Galileo continued on its mission to study Jupiter, beginning its orbit of the planet on 7 Dec 1995. | |||
||1995: Gerard A. "Gerry" Salton dies ... Professor of Computer Science at Cornell University. Salton was perhaps the leading computer scientist working in the field of information retrieval during his time, and "the father of Information Retrieval". His group at Cornell developed the SMART Information Retrieval System, which he initiated when he was at Harvard. Pic: http://www.cs.cornell.edu/Info/Department/Annual95/Faculty/Salton.html | |||
||2005: George Szekeres dies ... mathematician. He will discover the Szekeres snark, a snark with 50 vertices and 75 edges. Pic. | |||
||2006: Melvin Schwartz dies ... physicist. He shared the 1988 Nobel Prize in Physics with Leon M. Lederman and Jack Steinberger for their development of the neutrino beam method and their demonstration of the doublet structure of the leptons through the discovery of the muon neutrino. Pic. | |||
||2007: Paul B. MacCready Jr. dies ... aeronautical engineer. He was the founder of AeroVironment and the designer of the human-powered aircraft that won the first Kremer prize. He devoted his life to developing more efficient transportation vehicles that could "Do more with less". Pic. | |||
