The shortest path between two truths in the real domain passes through the complex domain.~Jacques Salomon Hadamard
The 309th day of the year; 3095= 2,817,036,000,549. It is the smallest number whose fifth power contains all the digits 0 to 9. (Students, is there a smaller number that contains all the digits for some other power?)
In 1845, Michael Faraday, working in his laboratory at the Royal Institution, hung a piece of heavy glass between the poles of an electro-magnet and observed that the glass aligned itself across the lines of force of the magnet. He further experimented on many other substances, with similar results, a phenomena that he named diamagnetism. These investigations showed Faraday that magnetism was inherent within matter. This led to his lecture "Thoughts on Ray-vibrations" in April 1846, which he expanded in the following years into his field theory of electro-magnetism. This was the progenitor for mathematical descriptions formed by Thomson, and especially for the seminal work of James Clerk Maxwell. *TIS
In 1869, the first issue was published of the journal Nature, editted by astronomer Sir Norman Lockyer. The first issue included articles on astronomy, plants, moths, science teaching in schools, an obituary for Thomas Graham, paleontology and meeting notices. Nature remains one of the most popular and well respected science journals in the world, printing research articles from across a wide range of scientific fields. *TIS
1943 Robert Oppenheimer, working on the Manhatten Project, is so impressed by Richard Feynman that he writes his Physics dept chair at Berkeley to recommend that they hire him after the war. He includes in the recommendation, two comments by others of note; Hans Bethe stated that he would rather lose any two other men than Feynman from the project, and Wigner stated, "He is a second Dirac, only this time human." *Shaun Usher, Letters of Note web site
1952 Television makes its first foray into predicting a presidential election based on computer analysis of early returns. The Univac computer makes an incredibly accurate projection that the network doesn't think credible. Pre-election polls had predicted anything from a Democratic landslide to a tight race with the Demo candidate, Illinois Gov. Adlai Stevenson, slightly ahead of the Republican, five-star Gen. Dwight D. Eisenhower, Supreme Commander of Allied Forces in Europe in World War II. So it was a surprise at 8:30 p.m. Eastern time when Univac predicted Eisenhower would pile up 438 electoral votes to Stevenson's 93.
In New York, news boss Mickelson scoffed at putting the improbable prediction on air. In Philadelphia, Woodbury added new data to the mix. At 9 p.m. correspondent Charles Collingwood announced to the audience that Univac was predicting 8-7 odds for an Eisenhower win.
But wait! Back in Philly, Woodbury discovered that he'd mistakenly added a zero to Stevenson's totals from New York state. When he entered the correct data and ran it through Univac, he got the same prediction as before: Ike 438, Adlai 93,
As the evening wore on, an Eisenhower landslide gathered momentum. The final vote was 442 to 89. Univac was less than 1 percent off. *Wired.com
1969 Pakistan issued a stamp honoring Alhazen (ab¯u-‘Al¯ıal-Hasan ibn al-Hasan ibn al-Haytham) (965–c. 1040), astronomer and optician. Pictured is a diagram showing the reﬂection of light. [Scott #281]. *VFR
1652 Jan-Karel della Faille or Jean Charles de La Faille (1 March 1597 in Antwerp, Belgium - 4 Nov 1652 in Barcelona, Spain) was a Flemish Jesuit who was the first to determine the center of gravity of the sector of a circle. He proved that the centers of gravity of a sector of a circle, of a regular figure inscribed in it, of a segment of a circle, or of an ellipse lie on the diameter of the figure. These theorems are founded on a postulate from Luca Valerio's De centro gravitatis solidorum (1604). ... La Faille ended his work with four corollaries which revealed his ultimate goal: an examination of the quadrature of the circle. *SAU
1744 Johann(III) Bernoulli (4 Nov 1744 in Basel, Switzerland
- 13 July 1807 in Berlin, Germany) wrote a number of works on astronomy and probability theory. Bernoulli wrote a number of works on astronomy, reporting on astronomical observations and calculations, but these are of little importance. Strangely his most important contributions were the accounts of his travels in Germany which were to have a historical impact.
In the field of mathematics he worked on probability, recurring decimals and the theory of equations. As in his astronomical work there was little of lasting importance. He did, however, publish the Leipzig Journal for Pure and Applied Mathematics between 1776 and 1789.
He was well aware of the famous mathematical line from which he was descended and he looked after the wealth of mathematical writings that had passed between members of the family. He sold the letters to the Stockholm Academy where they remained forgotten about until 1877. At that time when these treasures were examined, 2800 letters written by Johann(III) Bernoulli himself were found in the collection. *SAU (See "A Confusion of Bernoulli's" by the Renaissance Mathematicus.)
1765 Pierre-Simon Girard (Caen, 4 November 1765 – Paris, 30 November 1836) was a French mathematician and engineer, who worked on fluids. A prodigy who invented a water turbine at age 10, Girard worked as an engineer at the École Nationale des Ponts et Chaussées. He was in charge of planning and construction of the Amiens canal and the Ourcq canal. He collaborated with Gaspard de Prony on the Dictionnaire des Ponts et Chaussées (Dictionary of Bridges and Highways). He wrote works on fluids and on the strength of materials.*Wik
1908 Viktor Vladimirovich Wagner, also Vagner (4 November 1908 – 15 August 1981) was a Russian mathematician, best known for his work in differential geometry and on semigroups. *Wik
1921 Andrew Mattei Gleason (November 4, 1921 – October 17, 2008) was an American mathematician and the eponym of Gleason's theorem and the Greenwood–Gleason graph. After briefly attending Berkeley High School (Berkeley, California) he graduated from Roosevelt High School in Yonkers, then Yale University in 1942, where he became a Putnam Fellow. He subsequently joined the United States Navy, where he was part of a team responsible for breaking Japanese codes during World War II. He was appointed a Junior Fellow at Harvard in 1946, and later joined the faculty there where he was the Hollis Professor of Mathematicks and Natural Philosophy. He had the rare distinction among Harvard professors of having never obtained a doctorate. He retired in 1992. He is well-known for his work on Hilbert's fifth problem.*Wik
1933 The Honorable Sir Charles Kuen Kao,(4 November 1933) is a Chinese-born American and British physicist who pioneered in the development and use of fiber optics in telecommunications. Kao, known as the "Godfather of Broadband", "Father of Fiber Optics" or "Father of Fiber Optic Communications", was awarded half of the 2009 Nobel Prize in Physics for "groundbreaking achievements concerning the transmission of light in fibers for optical communication". Kao holds dual citizenship in Great Britain and the United States. *Wik

1698 Erasmus Bartholin (13 Aug 1625, 4 Nov 1698) Danish physician, mathematician , physicist, died in Copenhagen. He discovered the optical phenomenon of double refraction. In 1669, Bartholin observed that images seen through Icelandic feldspar (calcite) were doubled and that, when the crystal was rotated, one image remained stationary while the other rotated with the crystal. Such behaviour of light could not be explained using Isaac Newton's optical theories of the time. Subsequently, this was explained as the effect of the polarisation of the light. Bartholin wrote a large number of mathematical works, and made astronomical observations, including the comets of 1665. He is also famed for his medical work, in particular his introduction of quinine in the fight against malaria.*TIS
1917 William Du Bois Duddell (1872- 4 Nov 1917) English electrical engineer who invented the sensitive moving coil oscillograph able to photographically record a light spot tracing the oscillations of an electrical voltage, and other electrical instruments. He devised what may be regarded as the first electric musical instrument, the Singing Arc (1899), based on the sounds emitted by an electric carbon arc lamp when its supply voltage was varied. It was an outcome of his investigation to solve the problem of the undesirable humming or whining noises generated by carbon arc street lighting. This research discovered an associated principle of negative resistance. The audio frequencies were generated by switching suitable resonant circuits to the arc. Duddell died aged only 45 years old. *TIS
1954 Archibald Read Richardson (21 Aug 1881 in London, England - 4 Nov 1954 in Cape Town, South Africa) graduated from Imperial College London and then taught at the college. He was badly wounded in World War I. He became Professor of Mathematics at Swansea. His main interests were in algebra. *SAU
