On This Day in Math - May 14

 




“I have found a very great number of exceedingly beautiful theorems.”
 
Pierre de Fermat


The 134th day of the year; 134 has only two prime factors (67 and 2){called a bi-prime or a semiprime, it is the 45th semiprime of the year to date.} . Note that 1342 - 672 = 13467, which is the base numbers concatenated. *Prime Curios

134 is the sum of 8C1 + 8C3 + 8C4


134 is the 19th day of the year that is the sum of three positive cubes.


And 134 is the maximal number of regions the plane can be divided with 12 circles.

It is not possible to append a single digit to 134 and produce a prime. 

In this politically charged atmosphere, individuals in the military might want to be aware that, the American UCMJ; Article 134 is the catch-all article, for offences "not specifically mentioned in this chapter." Used to prosecute a wide variety of offences, from cohabitation by personnel not married to each other to statements critical of the U.S. President. Some prisoners, including Abu Ghraib were tagged with this number. Wik



EVENTS


May 14, 1230 "On the 14th May, which was the Tuesday in Rogation Week, the unusual eclipse of the Sun took place very early in the morning, immediately after sunrise; and it became so dark that the labourers, who had commenced their morning's work, were obliged to leave it, and returned again to their beds to sleep; but in about an hour's time, to the astonishment of many, the Sun regained its usual brightness." Refers to the total solar eclipse of 14 May 1230. From: Rogerus de Wendover, Flores Historiarum, vol.

1539 Georg Joachim Rheticus writes from Posen to his teacher/friend Johannes Schoener in Nuremberg to tell him he is on the way to visit Copernicus. It may well have been Schoener that urged him to visit Copernicus. No record of the letter itself exists, but it was mentioned in the dedication of the Narratio prima by Rheticus sent to Schoener in 1540 while Rheticus was still studying with Copernicus. *John W. Hessler, A Renaissance Globemaker's Toolbox


1607 The first permanent English settlement in American was founded at Jamestown, VA. *VFR


1631 Pierre de Fermat installed at Toulouse, at age 31, as commissioner of requests. *VFR He would retain the position until his death.


1743 In a letter to Nikolaus Bernoulli in 1743, Euler writes 1 + x + x2 + ... +  xn. One of the first uses of ellipses for series.  Cajori states earlier use was most commonly "etc." or "&c." 


1755 Joseph Louis Vincens de Mauleon, governor of the principality of Orange, published his “proof” that the circle could be squared. He claimed this proof enabled him to explain the mysteries of original sin and of the Holy Trinity.Although he offered a prize of 300,000 franks to anyone who could show his proof fallacious, it is pure nonsense. *VFR




1791, the twenty-one year old Alexander von Humboldt wrote a to the Prussian minister and director of the Mining and Smelting Department (Bergwerks- und Hüttendepartment) in Berlin. In the letter he described his ‘plan’ (Entwurf) for his ‘future public life.’ Young Humboldt had manifold interests, but in spring 1791 he had made up his mind. He wanted to serve his Fatherland, not as a member of the military, but as a scientifically trained, practical mining official.
‘I am of the age,’ he stated, ‘in which I must desire to enter a certain sphere of activity, and to become useful to my Fatherland through the minor forces I sense within me.’ His wish to join von Heynitz's mining department and to ‘undergo comprehensive training’ in his department, he further explained, was motivated by ‘the decisive inclination for mineralogy [and] for the science of salt works and mining (Salz- und Bergwerkskunde)’ along with ‘the hope, one day perhaps to contribute to the large and beneficial plans’ through which von Heynitz, based on the ‘principles of state economy,’ had ‘opened new sources of national wealth. *Ursula Klein,The Prussian Mining Official Alexander von Humboldt, Annals of Science, 2012




1832 "In March 1832 a cholera epidemic swept Paris and prisoners, including Galois, were transferred to the Pension Sieur Faultrier. There he apparently fell in love with Stephanie-Felice du Motel, the daughter of the resident physician. After he was released on 29 April Galois exchanged letters with Stephanie, and it is clear that she tried to distance herself from the affair. The name Stephanie appears several times as a marginal note in one of Galois' manuscripts." *SAU On May 14, Galois received a rejection letter from Stephanie. (Am I the only one who finds it funny that he met a woman named Motel in a Pension.)




1910 Halley's comet was big news during its visible period in New York City. Beginning with the Saturday edition of May 14 and continuing on through the Sunday edition of May 22, the comet was given top billing in the New York Times. This was the period when the comet was at the height of its brilliance and activity and the coverage clearly reflected this. "May 14: NYC hotel roofs being used for comet parties; Professor S. A. Mitchell tells of superstitions surrounding comets through the ages in NYC speech." *Joseph M. Laufer, Halley's Comet Society - USA

Mary Proctor FRAS FRMetS (1 April 1862 – 11 September 1957) was a British-American popularizer of astronomy. While not a professional astronomer, Proctor became well known for her books and articles written for the public – particularly her children's fiction.





1953 Results of the third annual MAA Mathematics Contest for high school students were announced. Tied for fourth place was Geraldine Anne Ferraro who later became the first woman vice-presidential nominee of a major political party. *VFR



1963  Yvonne Choquet-Bruhat became the first woman full member of the French Academy of Sciences.  She was a French mathematician and physicist who made important contributions to the general theory of relativity.

 She has made seminal contributions to the study of Einstein's general theory of relativity, by showing that the Einstein equations can be put into the form of an initial value problem which is well-posed. In 2015, her breakthrough paper was listed by the journal Classical and Quantum Gravity as one of thirteen 'milestone' results in the study of general relativity, across the hundred years in which it had been studied.




BIRTHS

1679 Peder [Nielsen] Horrebow (Horrebov) (14 May 1679; Løgstør, Jutland – 15 April 1764; Copenhagen) From 1703 to 1707, he served as an assistant to Ole Rømer and lived in Rømer's home. He worked as a household tutor from 1707 to 1711 to a Danish baron, and entered the governmental bureaucracy as an excise writer in 1711.
After repeatedly petitioning King Frederick IV, Horrebow became professor of mathematics at the University of Copenhagen in 1714. He also became director of the university's observatory (called the Rundetårn, "the Round Tower"). His son Christian succeeded him in this position. Horrebow and his wife, Anne Margrethe Rossing, had a total of 20 children.
In 1728, the great fire of Copenhagen destroyed all of the papers and observations made by Rømer, who had died in 1710. Horrebow wrote the Basis Astronomiae (1734–35), which describes the scientific achievements made by Rømer. Horrebow's own papers and instruments were destroyed in the same fire. Horrebow was given a special grant from the government to repair the observatory and instruments. Horrebow received further support from a wealthy patron.
Horrebow invented a way to determine a place's latitude from the stars. The method fixed latitude by observing differences of zenith distances of stars culminating within a short time of each other, and at nearly the same altitude, on opposite sides of the zenith. The method was soon forgotten despite its value until it was rediscovered by the American Andrew Talcott in 1833. It is now called the Horrebow-Talcott Method.
He wrote on navigation and determined the sun parallax, 9", an approximative solution to the Kepler equation. Horrebow also learned how to correct inherent flaws in instruments. This preceded Tobias Mayer's theory of correction of 1756.
Horrebow was a member of a number of scientific societies, including the Académie des Sciences (from 1746). He also worked as a medical doctor and as an academic notary (from 1720). *Wik




1701 William Emerson (14 May 1701 – 20 May 1782), English mathematician, was born at Hurworth, near Darlington, where his father, Dudley Emerson, also a mathematician, taught a school. William himself had a small estate in Weardale called Castle Gate situated not far from Eastgate where he would repair to work throughout the Summer on projects as disparate as stonemasonry and watchmaking. Unsuccessful as a teacher, he devoted himself entirely to studious retirement. Possessed of remarkable energy and forthrightness of speech, Emerson published many works which are singularly free from errata.

In The Principles of Mechanics (1754) he shows a wind-powered vehicle in which the vertically mounted propeller gives direct power to the front wheels via a system of cogs. In mechanics he never advanced a proposition which he had not previously tested in practice, nor published an invention without first proving its effects by a model. He was skilled in the science of music, the theory of sounds, and the ancient and modern scales; but he never attained any excellence as a performer. He died on 20 May 1782 at his native village, where his gravestone bears epitaphs in Latin and Hebrew.

Emerson dressed in old clothes and his manners were uncouth. He wore his shirt back to front and his legs wrapped in sacking so as not to scorch them as he sat over the fire. He declined an offer to become FRS because it would cost too much after all the expense of farthing candles he had been put to in the course of his life of study. Emerson rode regularly into Darlington on a horse like Don Quixote's, led by a hired small boy. In old age, plagued by the stone, he would alternately pray and curse, wishing his soul 'could shake off the rags of mortality without such a clitter-me-clatter.' *Wik





1832 Rudolf Otto Sigismund Lipschitz (14 May 1832 – 7 October 1903)  is remembered for the "Lipschitz condition", an inequality that guarantees a unique solution to the differential equation y' = f (x, y). *SAU
Lipschitz discovered Clifford algebras in 1880, two years after William K. Clifford (1845–1879) and independently of him, and he was the first to use them in the study of orthogonal transformations. Up to 1950 people mentioned “Clifford-Lipschitz numbers” when they referred to this discovery of Lipschitz. Yet Lipschitz’s name suddenly disappeared from the publications involving Clifford algebras; for instance Claude Chevalley (1909–1984) gave the name “Clifford group” to an object that is never mentioned in Clifford’s works, but stems from Lipschitz’s. Pertti Lounesto (1945–2002) contributed greatly to recalling the importance of Lipschitz’s role. *Wik




1863 John Charles Fields (May 14, 1863 - August 9, 1932) born in Toronto, Canada. After earning his Ph.D. at Johns Hopkins in 1887, he taught at Allegheny College (1889-1892) before going to Europe for a decade to study in Paris and Berlin. In 1902 he joined the faculty at the University of Toronto, where he remained until his death on 9 August 1932. *VFR
He originated the idea, posthumously given his name - for the Fields Medal. It became the most prestigious award for mathematicians, often referred to as the equivalent of a Nobel Prize for mathematicians. As a professor at the University of Toronto, he had worked to bring the International Congress of Mathematicians to Toronto (1924). The Congress was so successful that afterward there was a surplus of about \($2,500\) which Fields, as chairman of the organizing committee, proposed be used to fund two medals to be awarded at each of future Congresses. This was approved on 24 Feb 1931. He died the following year, leaving \($47,000\) as additional funding for the medals, which have been awarded since 1936. *TIS






1875  Beppo Levi (14 May 1875 – 28 August 1961) was an Italian mathematician. He published high-level academic articles and books, not only on mathematics, but also on physics, history, philosophy, and pedagogy. Levi was a member of the Bologna Academy of Sciences and of the Accademia dei Lincei.

His early work studied singularities on algebraic curves and surfaces. In particular, he supplied a proof (questioned by some) that a procedure for resolution of singularities on algebraic surfaces terminates in finitely many steps. Later he proved some foundational results concerning Lebesgue integration, including what is commonly known as Beppo Levi's lemma.



1878  Roland George Dwight Richardson (born May 14, 1878, Dartmouth, Nova Scotia; died July 17, 1949, Antigonish, Nova Scotia) was a prominent Canadian-American mathematician chiefly known for his work building the math department at Brown University and as Secretary of the American Mathematical Society.

Richardson was the Secretary of the American Mathematical Society in 1921 and held the job until 1940. During his time, Raymond Clare Archibald wrote in his article on Richardson, "No American mathematician was more widely known among his colleagues and the careers of scores of them were notably promoted by his time-consuming activities in their behalf." He was credited with helping many European mathematicians concerned about conditions in Europe move to America during the 1930s.

At the start of World War II Richardson organized accelerated applied mathematics courses at Brown for servicemen as the "Program of Advanced Instruction and Research in Applied Mechanics", recruiting German mathematician William Prager to lead it. This led to the founding of a new "Quarterly of Applied Mathematics" edited at Brown in 1943. After the war the program was converted into a new graduate division of applied mathematics. From 1943 to 1946 he was a member of the applied mathematics panel of the National Defense Research Committee.




1917 William Thomas Tutte FRS (May 14, 1917 – May 2, 2002) was a British, later Canadian codebreaker and mathematician. During World War II he broke a major German code system, which had a significant impact on the Allied invasion of Europe. He also had a number of significant mathematical accomplishments, including foundation work in the fields of combinatorics and graph theory. *Wik;




1925 Yuval Ne'eman (14 May 1925 – 26 April 2006) was an Israeli theoretical physicist, military scientist, and politician. 
An Israeli theoretical physicist, who worked independently of Gell-Mann but almost simultaneously (1961) devised a method of grouping baryons in such a way that they fell into logical families. Now known as the Eightfold Way (after Buddha's Eightfold Path to Enlightenment and bliss), the scheme grouped mesons and baryons (e.g., protons and neutrons) into multiplets of 1, 8, 10, or 27 members on the basis of various properties. He had served as the head of his Israel's atomic energy commission, and  founded the country's space program.



DEATHS

1669 Denis de Sallo, Sieur de la Coudraye (1626 - May 14, 1669) was a French writer and lawyer from Paris, known as the founder of the first French literary and scientific journal - the Journal des sçavans.
De Sallo obtained classical education and was admitted to the Paris bar in 1652, although he later devoted himself to scholarly aspects of the law rather than active practice, serving also as a counsel in the French government. He belonged to the clique of Jean-Baptiste Colbert, minister of finance under Louis XIV, and had active contacts with other prominent European scholars.
In 1665 he published the first issue of the Journal des sçavans under the pseudonym Sieur d'Hédouville. The idea for the journal was similar in scope to an outline written by the historian François Eudes de Mézeray who also belonged to the Colbert's clique and briefly lived in the same household as de Sallo. It included recording news and inventions in the various arts and sciences, decisions of secular and ecclesiastical courts, reviews of new scholarly books and other items of broader interest to a modern scholar.
De Sallo's health deteriorated in his final years so that he was unable to walk; his condition has been attributed to diabetes. *Wik




1761 Thomas Simpson (20 August 1710 – 14 May 1761) is best remembered for his work on interpolation and numerical methods of integration. However the numerical method known today as "Simpson's rule", although it did appear in his work, was something he learned from Newton as Simpson himself acknowledged. By way of compensation, however, the Newton-Raphson method for solving the equation f (x) = 0 is, in its present form, due to Simpson. Newton described an algebraic process for solving polynomial equations which Raphson later improved. The method of approximating the roots did not use the differential calculus. The modern iterative form xn+1 = xn - f (xn) / f '(xn) is due to Simpson, who published it in 1740. *SAU





1797 Giovanni Francesco Fagnano dei Toschi (31 Jan 1715 in Sinigaglia, Italy - 14 May 1797 in Sinigaglia, Italy) He proved that the triangle which has as its vertices the bases of the altitudes of any triangle has those altitudes as its bisectors. *VFR Of all the triangles that could be inscribed in a given triangle, the one with the smallest perimeter is the orthic triangle. This has sometimes been called Fagnano's Problem since it was first posed and answered by Giovanni Francesco Fagnano dei Toschi. Fagnano also was the first to show that the altitudes of the original triangle are the angle bisectors of the orhtic triangle, so the incenter of the orthic triangle is the orthocenter of the original triangle.*pb





1893 Ernst Eduard Kummer (29 January 1810 – 14 May 1893)  He was professor at the University of BRESLAU (now WROCLAW, Poland) in 1842-1855 and developed his theory of ideals here. KRONECKER studied with him. Later he replaced Dirichlet at The University of Berlin. He died at age 83, after a short attack of influenza. German mathematician whose introduction of ideal numbers, which are defined as a special subgroup of a ring, extended the fundamental theorem of arithmetic to complex number fields. He worked on Function theory, and  extended Gauss's work on hypergeometric series, giving developments that are useful in the theory of differential equations. He was the first to compute the monodromy groups of these series. Later. Kummer

devoted himself to the study of the ray systems, but treated these geometrical problems algebraically. He also discovered the fourth order surface based on the singular surface of the quadratic line complex. This Kummer surface has 16 isolated conical double points and 16 singular tangent planes.  *TIS and others   An oft told, and almost certianly untrue anecdote is told about Kummer: Kummer was so inept at simple arithmetic that he often asked students to help him in class. On one occasion, Kummer sought the result of a simple multiplication. "Seven times nine," he began. "Seven times nine is er - ah - ah - seven times nine is..." "Sixty-one," a mischievous student suggested and Kummer wrote the "answer" on the blackboard. "Sir," another one interjected, "it should be sixty-seven." "Come,  gentlemen, it can't be both," Kummer exclaimed. "It must be one or the other!" According to Erdos, Kumer reasoned out the answer as follows, -It can't be 61 as that is prime, as is 67, and 65 is a multiple of five, and 69 is too big, so it must be 63.


1924 Enrico Barone (December 22, 1859, Naples – May 14, 1924, Rome) Italian mathematical economist who built on the general equilibrium theory of Léon Walras and was instrumental in convincing Walras to incorporate variable production techniques - and, by extension, marginal productivity theory - into the Walras theory. Barone's greatest contribution was in getting the "Socialist Calculation" debate started with his famous 1908 article. His position was that it was indeed possible in a collectivist state for a planning agency to calculate prices for maximum efficiency. He was the first to apply indifference curve analysis to compare the relative burdens of income taxes and excise taxes (1912). He opposed "progressive" taxation schemes as based on dubious utilitarian calculations. *TIS




1985 Charles Leonard Hamblin (20 November 1922 – 14 May 1985) was an Australian philosopher, logician, and computer pioneer, as well as a professor of philosophy at the New South Wales University of Technology (now the University of New South Wales) in Sydney.
Among his most well-known achievements in the area of computer science was the introduction of Reverse Polish Notation and the use in 1957 of a push-down pop-up stack. This preceded the work of Friedrich Ludwig Bauer and Klaus Samelson on use of a push-pop stack. The stack had been invented by Alan Turing in 1946 when he introduced such a stack in his design of the ACE computer. Hamblin's most well-known contribution to philosophy is his book Fallacies, a standard work in the area of the false conclusions in logic. *Wik





2021 Yuan Wang (29 April 1930 in Lanhsi, Zhejiang province, China - 14 May 2021) )Most of Wang Yuan's research has been in the area of number theory. He looked at sieve methods and applied them to the Goldbach Conjecture. He also applied circle methods to the Goldbach Conjecture. In 1956 he published (in Chinese) On the representation of large even integer as a sum of a prime and a product of at most 4 primes in which he assumed the truth of the Riemann hypothesis and with that assumption proved that every large even integer is the sum of a prime and of a product of at most 4 primes. He also proved that there are infinitely many primes p such that p + 2 is a product of at most 4 primes. In 1957 Wang Yuan published four papers: On sieve methods and some of their applications; On some properties of integral valued polynomials; On the representation of large even number as a sum of two almost-primes; and On sieve methods and some of the related problems.*SAU



1923 Alexander Murray Macbeath (30 June 1923 Glasgow – 14 May 2014 Warwick)was a mathematician who worked on Riemann surfaces. Macbeath surfaces and Macbeath regions are named after him.

During World War II, he worked in Hut 7 of the Government Code and Cypher School at Bletchley Park, breaking ciphers used for military communications by the Japanese navy and, later, the army.

After the war he earned an M.A. (again with honours) from Clare College, Cambridge. With a Commonwealth Fund fellowship, he then attended Princeton University, where he earned his Ph.D. in 1950 under the supervision of Emil Artin.
He taught at Keele University and the University of Dundee before moving to the University of Birmingham in 1963 where he stayed until 1979 as Mason Professor,[3] then moved back to the University of Pittsburgh in the United States until he reached their statutory retirement age of 60.

He subsequently took up a position at the University of Dundee where he remained for a number of years, before moving to Warwickshire where at the University of Warwick he held the position of Emeritus Professor of Mathematics.*Wik
