JANUARY 13 – BIRTHS – Scientists born on January 13th
  Sydney Brenner
baby icon  Born 13 Jan 1927.  quotes button quotes
South African biologist who shared (with H. Robert Horvitz and John E. Sulston) the Nobel Prize in Physiology or Medicine for 2002 for their discoveries concerning how the genes regulate organ development and programmed cell death (apoptosis). Brenner established Caenorhabditis elegans as a model organism for the investigation of animal development including neural development. He chose this organism, a 1-mm-long soil roundworm, because of its simple structure, ease to grow in bulk populations, and finding that it is convenient for genetic analysis.

Austrian-American philosopher of science.
  Ross Granville Harrison
baby icon  Born 13 Jan 1870; died 30 Sep 1959 at age 89.
American zoologist who developed the first successful animal-tissue cultures and pioneered organ transplantation techniques. In an early experiment, using tissue grafting techniques, he joined parts of embryos from differently coloured frogs to observe the movement of cells during the subsequent development of the embryos produced in this way. In another experiment, he took tissue from an amphibian embryo that would have formed a left limb, inverted and transferred it to the embryo's right side, where it formed a right limb. He discovered the hanging-drop culture method (1907), a new method of studying cells, by which he kept fragments of living tissue alive in suitable media and watch them multiply. Using this technique, he settled a controversy about the embryonic origins of nerve fibres. The hanging-drop method has also been valuable in oncology, genetics, virology and other fields.
  Wilhelm Wien
baby icon  Born 13 Jan 1864; died 30 Aug 1928 at age 64.  quotes button quotes
German physicist who received the Nobel Prize for Physics in 1911 for his displacement law concerning the radiation emitted by the perfectly efficient blackbody (a surface that absorbs all radiant energy falling on it). While studying streams of ionized gas Wien, in 1898, identified a positive particle equal in mass to the hydrogen atom. Wien, with this work, laid the foundation of mass spectroscopy. J. J. Thomson refined Wien's apparatus and conducted further experiments in 1913 then, after work by Ernest Rutherford in 1919, Wien's particle was accepted and named the proton. Wien also made important contributions to the study of cathode rays, X-rays and canal rays.
  Oskar Minkowski
baby icon  Born 13 Jan 1858; died 18 Jul 1931 at age 73.
German physiologist and pathologist who introduced the concept that diabetes results from suppression of a pancreatic substance (later found to be the hormone insulin). After studying how fat is metabolized by the body, in 1889, Oskar Minkowski and Joseph von Mering uncovered the role of the pancreas in diabetes. In an experiment in which they removed the pancreas from a dog, it consequently developed diabetes. He was the brother of mathematician Hermann Minkowski (whose idea of a four-dimensional or "Minkowski space", laid the mathematical foundation of Albert Einstein's general theory of relativity). Oskar's son, Rudolf Minkowski was a physicist and astronomer.
  Fιlix Tisserand
baby icon  Born 13 Jan 1845; died 20 Oct 1896 at age 51.
Franηois-Fιlix Tisserand was a French astronomer whose 4-volume textbook Traité de mécanique céleste (1889-96; "Treatise on Celestial Mechanics") updated Pierre-Simon Laplace's work. At age 28, he was named Director at Toulouse Observatory (1873-78). He went to Japan to observe the 1874 transit of Venus. The 83-cm telescope he installed at the Toulouse Observatory in 1875 had a wooden base insufficiently stable for photographic work, but he was able to use it for observation of the satellites of Jupiter and of Saturn. From 1892 until his death he was director of the Paris Observatory, where he completed the major work, Catalogue photographique de la carte du ciel, and arranged for its publication.« [Image right: Tisserands's 83-cm telescope.]

baby icon  Born 13 Jan 1804; died 19 Sep 1859 at age 55.  quotes button quotes
Scottish astronomer and author who, after a few years early in his career as a teacher and headmaster, was appointed in 1836 as Regius Professor of Practical Astronomy at the University of Glasgow, where he spent the rest of his life. While in this position, he also became a popular public lecturer on astronomy and wrote a number of books on science. His fund-raising efforts paid for a new observatory at Horeslethill (1841), which was acquired by the University in 1845. While giving lectures in Natural Philosophy during the two-year absence during the illness of a colleague, it is said he inspired William Thomson as a young student who later became the famed Lord Kelvin. Nichols' last complete work was a Dictionary of the Physical Sciences.


Nature bears long with those who wrong her. She is patient under abuse. But when abuse has gone too far, when the time of reckoning finally comes, she is equally slow to be appeased and to turn away her wrath. (1882) -- Nathaniel Egleston, who was writing then about deforestation, but speaks equally well about the danger of climate change today.
Carl Sagan Thumbnail Carl Sagan: In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) ...(more by Sagan)

Albert Einstein: I used to wonder how it comes about that the electron is negative. Negative-positive—these are perfectly symmetric in physics. There is no reason whatever to prefer one to the other. Then why is the electron negative? I thought about this for a long time and at last all I could think was “It won the fight!” ...(more by Einstein)

Richard Feynman: It is the facts that matter, not the proofs. Physics can progress without the proofs, but we can't go on without the facts ... if the facts are right, then the proofs are a matter of playing around with the algebra correctly. ...(more by Feynman)

JANUARY 13 – DEATHS – Scientists died on January 13th
  Paul Niggli
gravestone icon  Died 13 Jan 1953 at age 64 (born 26 Jun 1888).
Swiss mineralogist who originated the idea of a systematic deduction of the patterns in the internal structure of crystals by means of X-ray data. He supplied a complete outline of methods that have since been used to determine these patterns. There are 230 possible different internal patterns for different crystals. Because the patterns describe a three-dimensional arrangement, they are known as space groups. Niggli also developed a notation that described the individual space groups, and co-authored a definitive set of tables describing them.  read more button more
  Paul Urich Villard
gravestone icon  Died 13 Jan 1934 at age 73 (born 28 Sep 1860).
Paul-Urich Villard was a French physicist and chemist who in 1900 identified a third kind of natural radiation, later called gamma rays. He was studying the radiations from uranium salts discovered by Henri Becquerel four years before. Charged particles whose paths were bent in a magnetic field were known, but Villard found a form of penetrating radiation that was not deviated, but it drew little attention from contemporary scientists. A year before, in 1899,  Ernest Rutherford named the first two kinds of natural radiation—positive alpha particles and negative beta rays. The third kind became known as gamma rays—with energy higher than X-rays, weak power of ionization, and which Rutherford characterized (1914) as a form of electromagnetic radiation, like light. Villard invented several radiological instruments, including the osmoregulator and Villard's valve. He researched hydrates, and discovered silver hydrate. He wrote Les Rayons Cathodiques (1900).« [Ref: 'Les rayons cathodiques et les rayons Roentgen', Bulletin de la Sociιtι Internationale des Electriciens, XVII/I (1900), 169-184. He read his paper to the society in Apr 1900.]
  Sebastian Ziani de Ferranti
gravestone icon  Died 13 Jan 1930 at age 65 (born 9 Apr 1864).
English electrical engineer who promoted the installation of large electrical generating stations and alternating current distribution networks in England. He was interested in electrical and mechanical devices as a youth, and in 1881, began such employment while in his late teens. In his 20's, he began planning an ambitious generating station about 8 miles outside London, to use transmission at an unprecedented 10,000 volts - four times greater than previously practical. For this he began designing suitable cables, transformers and generators. His idea of making high voltage flexible cables using wax-impregnated paper for insulation was a landmark development used exclusively until the advent of synthetic materials. His 176 patents cover varied inventions.

  Alexander Stepanovich Popov
gravestone icon  Died 13 Jan 1906 at age 46 (born 16 Mar 1859).
Russian physicist.
  Peter Waage
gravestone icon  Died 13 Jan 1900 at age 66 (born 29 Jun 1833).
Norwegian chemist who, with his brother-in-law Cato Guldberg published the mass action law in 1864. The law states that the rate of a chemical change depends on the concentrations of the reactants. Thus for a reaction: A + B —> C the rate of reaction is proportional to [A][B], where [A] and [B] are concentrations. They also investigated the effects of temperature. Their work did not gain full credit at the time, partly due to their first publishing the law in Norwegian. Even when published in French (1867) the law received little attention. Waage later turned to practical problems relating to nutrition and public health, and he also engaged in social and religious work. (The law was rediscovered by William Esson and Vernon Harcourt.)
  Robert Adams
gravestone icon  Died 13 Jan 1875 (born c. 1791).
Irish surgeon known for his contributions to the knowledge of heart, respiratory, vascular and joint diseases, particularly on gout (which he suffered himself). In 1827 he described a condition characterized by a very slow pulse and by transient giddiness or convulsive seizures, now known as the Adams-Stokes disease or syndrome.
  Henri Braconnot

glucose

gravestone icon  Died 13 Jan 1855 at age 73 (born 29 May 1781).
French naturalist and chemist known for isolating glucose, a simple sugar, directly from such plant material as sawdust, linen or bark by boiling them with acid (1819). Previously, glucose had only been derived from starch. In 1811, he was the first to find fungtine - in mushrooms. (It was named chitin in the 1830's when it was also isolated in insects.) Chitin is one of the most abundant polysaccharides found in nature. In 1832, Braconnot prepared “xyloidine” by treating starch, sawdust, and cotton with nitric acid. He found that this material was soluble in wood vinegar and attempted to make coatings, films, and shaped articles from it. This was an early discovery preceding the work of other scientists with nitrocellulose that led to the advent of plastics and rayon.
  Jeremiah Horrocks
gravestone icon  Died 13 Jan 1641 (born 1618).
English astronomer and clergyman who applied Johannes Kepler's laws of planetary motion to observations of the Moon and Venus. Once Horrocks managed to obtain a small telescope, his observations convinced him that Lansberg's tables were incorrect. He accepted Kepler's elliptical orbits, and in working on the moon he applied an elliptical orbit to it and established that the line of apsides precessed, an effect which he ascribed to the influence of the sun. Horrocks predicted and observed a transit of Venus on 24 Nov 1639, the first one ever observed, and from the observation he corrected the solar parallax, indicating a much greater distance of the sun than anyone before him had admitted. He died at age only 22. [DSB gives dates as 1618 - 13 Jan 1641. EB gives 1617 - 3 Jan 1641.]

JANUARY 13 – EVENTS – Science events on January 13th
  Female astronauts
calendar icon   In 1978, NASA selected its first U.S. women astronauts.
  Reading for the blind
calendar icon   In 1976, the first machine for reading printed matter aloud was given its first public demonstration, by its inventor, Raymond Kurzwell. Using a camera with a computer, pages of printed matter could be scanned, the letters analysed, and reproduced in synthesized English speech at 150 words per minute. The material used could be books, magazines or typewritten correspondence. The machine was manufactured by the Kurzwell Computer Products, Inc., and was tested by the National Federation for the Blind.
  Petition
Thumbnail - Petition
Pauling
calendar icon   In 1958, Linus Pauling (1901-1994) presented the petition of 9,000 scientists to the U.N., asking to halt the testing of nuclear bombs. Pauling, together with his wife, was instrumental in collecting thousands of signatures from scientists all over the world for the petition to end nuclear bomb testing, which was presented to Dag Hammarskjöld, secretary general of the United Nations. A few months later the Soviet Union called for an immediate halt to nuclear testing, and in October, after more tests by both sides that added markedly to world concern about fallout, talks began in Geneva to discuss details of a possible test ban.

  Frisbee
Thumbnail - Frisbee
calendar icon   In 1957, the Wham-O Company developed the first frisbee. A representative of the company got the idea for the product when he saw some truck drivers from the Frisbee Pie Co. of Connecticut showing Yale students how to throw pie pins in the air. On 26 Dec 1967, a U.S. patent was issued to the Wham-O Mfg. Co. for their improvement of the Frisbee (U.S. No. 3,359,678) - an “aerodynamic toy to be thrown through the air … in throwing games.” It was described as a saucer shaped throwing implement with a series of concentric discontinuities adjacent the rim on its convex side. Image: patent diagrams of the Frisbee.
  Ejection seat first used
calendar icon   In 1942, the first use of an ejection seat to save a pilot was made. Helmut Schenk, a German test pilot, required its use when his Heinkel He 280 refused to separate from the tow aircraft due to the cable release mechanism icing up. As a precaution, Schenk ejected and landed safely. The tow was being made because the He-280 was powered by two Argus pulse-jets that required a high forward speed to start up. The first ejection seat was made by Heinkel, for the He 280. It was powered by compressed air, and accelerated the pilot upwards at between seven-g and nine-g. The He-280 was the first twin-jet engined aircraft and the first jet aircraft to go beyond prototype stage. The earliest known experiment to produce an airplane ejection seat took place on 12 Dec 1912. [Image: Heinkel He-162 ejection seat.]

  Plastic automobile patent
calendar icon   In 1942, the first U.S. patent for construction of an automobile using plastic was issued to Henry Ford of Dearborn, Mich. It covered an automobile body construction, an auto body chassis frame made of steel tubes or pipes designed for use with automobiles made from plastics. The first such car manufactured in the U.S. was produced by the Ford Motor Company, Dearborn, Mich. in Aug 1941. Fourteen plastic panels were mounted on a tubular welded frame. Together with windows and windshield made of acrylic sheets, a decrease in weight of approximately 30 percent was accomplished. (No. 2,269,451)
  Experimental TV sets installed
calendar icon   In 1928, three television sets were installed by RCA and GE in homes in Schenectady, New York. American inventor E.F.W. Alexanderson demonstrated the first home television receiver which delivered a poor and unsteady picture only 1.5 inches square. The picture, with 48 lines at 16 frames per second, was transmitted over 2XAF on 37.8 meters and the sound was transmitted over WGY radio station. The sets were in the homes of Alexanderson and two board members. On 28 May 1928, the first television station WGY began broadcasting regular programs on Tuesday, Thursday, and Friday afternoons from 1:30 to 3:30 pm, using 24 lines. Sets were built and distributed by General Electric in Schenectady.
  First one-kilometer circuit flight
calendar icon   In 1908, Henry Farman, an English-born Frenchman, flew the first one-kilometer circuit, winning the Grand Prix de Aviation and its 50,000 franc purse. He crossed the starting poles about 4-m (13-ft) in the air, then flew straight out for about 500-m. Slowly climbing to 12-m (40-ft) he then made a wide, flat turn, using rudder alone to slide around the marker. He came back and made another turn, crossed the point at which he started, and landed gently. The entire flight lasted 28-sec, and covered the prescribed kilometer. Although the Wrights may have accomplished this at an earlier date, this was the first such flight in front of official witnesses.
  First U.S. advertisement for a radio receiver
calendar icon   In 1906, this date is sometimes given for the first U.S. advertisement for a radio receiver. However, the earliest one-inch advertisement for the Telimco appeared in the 25 Nov 1905 issue of the Scientific American. Both these, and several similar weekly advertisements in between, were run by Hugo Gernsback of The Electro Importing Company of New York. It seems that Gernsback himself appeared to have forgotten the exact date on which the first Telimco advertisement appeared. The Electro Importing catalogs from the mid-teens state that the ads premiered in Scientific American in Nov 1905. However, in a special issue of Radio Craft published in Mar 1938, Gernsback gave the date as 13 Jan 1906.
  Granville Woods patent
calendar icon   In 1903, Black American inventor, Granville T. Woods, was issued a U.S. patent for an "Electric Railway System." of the type that "current for the car-motor is taken from working contacts or conductors along the road bed." The object of Woods' invention was to "insure safety from shock at the working conductor or contacts, reduce leakage to a minimum, economize current in the operation of the system, and at the same time provide a system which can be easily constructed and perfectly controlled." He assigned the right to the General Electric Company of New York. Woods produced many inventions relating to railways. (No. 718,183)

  Chenille manufacturing machine patented
calendar icon   In 1863, the first U.S. patent for a chenille manufacturing machine was issued to William Canter of New York City, who made the first such machine in the U.S. (No. 37,415)
  Railway track scale patent
calendar icon   In 1857, the first U.S. patent for a railway track scale was issued to Thaddeus Fairbanks (No. 16,381). Such a platform scale was introduced by the E. and T. Fairbanks and Company of St. Johnsbury, Vermont. It was designed to weigh railway cars either alone or in train. The platform of the scale was fitted with two rails arranged in line with the railway track such that cars and carriages could readily be rolled on and off. The mechanism beneath was set in a pit. It was constructed with suitable levers and bearings to permit weighing a great range of loads accurately. Thaddeus and his brother built their company's scale business starting over two decades earlier with their invention of a platform scale for merchandise, which they patented 30 Jun 1831.
  Accordion patent
calendar icon   In 1854, the first U.S. patent for an accordion was issued to Anthony Faas of Philadephia. Pa. (No. 11,062). Faas claimed two improvements. First, he combined with the diatonic scale of the large keys two other scales, namely, one for producing all the intermediate notes, or semitones, and the other founded upon the subdominant of said diatonic scale, and both arranged so as to be fingered by a single set of small keys for the purpose of enabling the instrument to produce full and correct harmony in any key. His second improvement consisted in providing the accordion with a sound-board, for the purpose of producing more strength, fullness and resonance of tone with the instrument.
  Postal scale
calendar icon   In 1840, a postal scale was registered by R.W. Winfield, of Birmingham. This “candlestick” pattern of spring scale was introduced at the same time as the penny post. R.W. Winfield & Co. was a large manufacturer of brass bedsteads, cots, sofas, chairs gas fittings, chandeliers and general brassfounder's items. The vertical scale on the left was calibrated up to 4 “oz,” with half-ounce divisions, and on the right  in "D" from up to 8d, since the postal rate was one penny per half ounce. Now, as an antique, a good specimen might auction for up to £500. [Image: a detail is inset, with a red mark added to highlight the scale pointer.]

  Callisto
Thumbnail - Callisto
(NASA)
calendar icon   In 1610, Galileo Galilei discovered Callisto, the fourth satellite of Jupiter. Galileo originally called the Jupiter's moons the “Medicean planets,” after the Medici family and referred to the individual moons numerically as I, II, III and IV. Galileo's naming system would be used for a couple of centuries. It wouldn't be until the mid-1800's that the names of the Galilean moons, Io, Europa, Ganymede and Callisto, would be officially adopted, and only after it became apparent that naming moons by number would be very confusing as new additional moons were being discovered. It is now known that Callisto is larger than the planet Mercury, and composed mostly of water and water ice with large quantities of ice exposed on the surface.

  Alchemy
calendar icon   In 1404, English alchemists were forbidden to use their knowledge to create precious metals. Since the time of Roger Bacon, it had fascinated the imagination of many ardent men in England. During the reign of Henry IV, the Act of Multipliers was passed by the Parliament, declaring the use of transmutation to “multiply” gold and silver to be felony. Great alarm was felt at that time lest any alchemist should succeed in his projects, and perhaps bring ruin upon the state, by furnishing boundless wealth to some designing tyrant, who would make use of it to enslave his country. In 1689, Robert Boyle lobbied for repeal of the Act.
