I learned to distrust all physical concepts as the basis for a theory. Instead one should put one's trust in a mathematical scheme, even if the scheme does not appear at first sight to be connected with physics. One should concentrate on getting interesting mathematics.
~ Paul DiracThe 153rd day of the year. 153 is the fixed point attractor of any multiple of three under the process of summing the cubes of the digits. For more detail and explanation see,"The Cubic Attractiveness of 153" ,
13+53 + 33 = 153. There are only three other numbers which are the sum of the cubes of their digits (Go fourth and seek them.) This makes 153 a narcissistic number. A number of n digits which is equal to the sum of the nth powers of its digits. There are 88 narcissistic numbers in base 10, but only 11 in base 4.
ALSO, 153 = 1! + 2! + 3! +4! +5!, *Jim Wilder@wilderlab
EVENTS1661 An eager Isaac Newton departs his farm home at Woolsthorpe for Trinity College, Cambridge, although the term would not begin until September. He would remain at Trinity for thirty-five years. He took almost nothing with him. *Thomas Levenson, Newton and The Counterfeiter
In 1686, the publication of Newton's Principia was arranged in London at the Royal Society. The minutes of the meeting record that the astronomer Edmund Halley would "undertake the business of looking after it and printing it at his own charge."
1692 – Bridget Bishop is the first person to go to trial in the Salem witch trials in Salem, Massachusetts. Found guilty, she is hanged on June 10.
In 1858, the Donati Comet was first seen and named after its discoverer, Giovanni Battista Donati, at Florence. It was the second-brightest comet of the nineteenth century It reached perihelion on 30 Sep 1858. When nearest the earth on 9 Oct 1858, it was about 0.5 AU away, and had developed a scimitar-shaped triple tail. At that time, its very prominent dust tail had with an apparent length of 50°, more than half the distance from the horizon to the zenith, a linear distance of over 72 million km (about 45 million mi). It was the first comet to be photographed. With an orbital period estimated at more than 2000 years, it will not return until about the year 4000. An astronomical unit, AU, equals 93 million miles, the Sun-Earth distance.
1913 Millikan announced the results of his experiment to measure the electron charge. *VFR
1924 – U.S. President Calvin Coolidge signs the Indian Citizenship Act into law, granting citizenship to all Native Americans born within the territorial limits of the United States.
1925 – Because of a lineup revision by Miller Huggins, Wally Pipp is replaced by Lou Gehrig at first base for the New York Yankees, beginning a streak of 2,130 consecutive games played, topped only by Cal Ripken, Jr. in 1995. Exactly 16 years later to the day, in 1941, Gehrig dies from Amyotropic lateral sclerosis (ALS).
1963 Between May 11 and June 2, Donald B. Gillies found three new primes. When the primes were confirmed the UIUC Math dept (which has a postal branch) used this cancellation stamp on all mail from roughly 1964 - 1976, when Appel and Haken proved the four color theorem ("Four Colors Suffice") and a new stamp was created. Trivia question : how far away from Gillies did Appel live in Urbana Illinois ??
Answer : He lived 3 houses away. *Wik

1966 Surveyor 1 Makes soft-landing on the moon. It was the first lunar soft-lander in the unmanned Surveyor program of the National Aeronautics and Space Administration (NASA, United States). It gathered data about the lunar surface that would be needed for the manned Apollo Moon landings that began in 1969. The successful soft landing of Surveyor 1 on the Ocean of Storms was the first by an American space probe onto any extraterrestrial body, and it occurred just four months after the first Moon landing by the Soviet Union's Luna 9 probe.
Surveyor 1 was launched May 30, 1966 and landed on the Moon on June 2, 1966. It transmitted 11,237 still photos of the lunar surface to the Earth by using a television camera and a sophisticated radio-telemetry system. *Wik
BIRTHS1884 Henry Thomas Herbert Piaggio(2 June 1884–26 June 1967) graduated from Cambridge and then worked at the University of Nottingham. He is best known for his text-book on Differential Equations.
1895 Tibor Radó (June 2, 1895 – December 29, 1965) was a Hungarian mathematician who moved to the USA after World War I. He was born in Budapest and between 1913 and 1915 attended the Polytechnic Institute. In World War I, he became a First Lieutenant in the Hungarian Army and was captured on the Russian Front. He escaped from a Siberian prisoner camp and, traveling thousands of miles across Arctic wasteland, managed to return to Hungary.
He received a doctorate from the University of Szeged in 1923. He taught briefly at the university and then became a research fellow in Germany for the Rockefeller Foundation. In 1929, he moved to the United States and lectured at Harvard University and the Rice Institute before obtaining a faculty position in the Department of Mathematics at Ohio State University in 1930. In 1935 he was granted American citizenship.
In the 1920s, he proved that surfaces have an essentially unique triangulation.
In 1933, Radó published "On the Problem of Plateau" in which he gave a solution to Plateau's problem, and in 1935, "Subharmonic Functions".
In World War II he was science consultant to the United States government, interrupting his academic career.
He became Chairman of the Department of Mathematics at Ohio State University in 1948.
His work focused on computer science in the last decade of his life and in May 1962 he published one of his most famous results in the Bell System Technical Journal: the Busy Beaver function and its non-computability ("On Non-Computable Functions").
In computability theory, a busy beaver (from the colloquial expression for an "industrious person") is a Turing machine that attains the maximum "operational busyness" (such as measured by the number of steps performed, or the number of nonblank symbols finally on the tape) among all the Turing machines in a certain class. The Turing machines in this class must meet certain design specifications and are required to eventually halt after being started with a blank tape. *Wik
1916 Abraham Seidenbergwas (June 2, 1916 – May 3, 1988) known for his research to commutative algebra, algebraic geometry, differential algebra, and the history of mathematics. He published Prime ideals and integral dependence written jointly with I S Cohen which greatly simplified the existing proofs of the going-up and going-down theorems of ideal theory. He also made important contributions to algebraic geometry. In 1950, he published a paper called The hyperplane sections of normal varieties which has proved fundamental in later advances. In 1968, he wrote Elements of the theory of algebraic curves, a book on algebraic geometry. He published several important papers.*Wik
DEATHS1785 Jean Paul de Gua de Malves, (1713, Carcassonne – June 2, 1785, Paris) In 1740 he published a work on analytic geometry which, without the differential calculus, he found tangents, asymptotes, and various singular points of an algebraic function. He gave the proof of Descartes rule of signs which is found in modern texts. It is not known if Descartes ever proved it, and Newton seemed to think it was "obvious". (A short account of the history of mathematics By Walter William Rouse Ball)
1929 Otto Schreier (3 March 1901 in Vienna, Austria - 2 June 1929 in Hamburg, Germany) He will be best remembered for his work on subgroups of free groups which he studied in his habilitation thesis. He published the results in 1927 in the paper Die Untergruppen der freien Gruppe which is described as "... one of the most important papers ever published on combinatorial group theory. It took a long time for all its aspects to become effective, and it contains much more than the title indicates. "
In January 1926 Schreier attended a lecture given by Reidemeister in Hamburg on finding presentations for normal subgroups of finitely presented groups. Reidemeister published his method later in 1926. Schreier, who took a more algebraic approach compared to Reidemeister's geometrical approach, was able to extend Reidemeister's method to arbitrary subgroups and, by cleverly choosing generators for the subgroup, was able to greatly simplify the presentation obtained. Schreier published his method in his 1927 paper Die Untergruppen der freien Gruppe.
Other work of Schreier is described as follows:
... Schreier made important contributions to other parts of group theory. The classical Lie groups ... can be considered as topological spaces. Schreier (1927) showed that the fundamental group of such a space is always abelian. Schreier (1928) found an important refinement of the fundamental Jordan-Hölder theorem, 39 years after the publication of Hölder's paper. It is rare that such a widely used and basic theorem can be deepened after such a long time. (In this case, something even more unusual happened. Zassenhaus (1934) discovered a second improvement of the theorem.)*SAU
1942 Andrew Russell Forsyth (18 June 1858, Glasgow – 2 June 1942, South Kensington) was a Scottish mathematician. He worked in diﬀerential equations, and function theory.
He studied at Liverpool College and was tutored by Richard Pendlebury before entering Trinity College, Cambridge, graduating senior wrangler in 1881. He was elected a fellow of Trinity and then appointed to the chair of mathematics at the University of Liverpool at the age of 24. He returned to Cambridge as a lecturer in 1884 and became Sadleirian Professor of Pure Mathematics in 1895. He resigned his chair in 1910 after an affair with Marion Amelia Boys, the wife of C. V. Boys, who divorced her husband to marry him: this was unacceptable in Edwardian Cambridge. He became professor at the Imperial College of Science in 1913 and retired in 1923, remaining mathematically active into his seventies. He was elected a Fellow of the Royal Society in 1886 and won its Royal Medal in 1897.
He is now remembered much more as an author of treatises, than as an original researcher. His books have, however, often been criticized (for example by J. E. Littlewood, in his Mathematician's Miscellany). E. T. Whittaker was his only official student, according to the Mathematical Genealogy site. *Wik
1946 William Peddie (31 May 1861 in Papa Westray, Orkney, Scotland - 2 June 1946 in Ninewells, Dundee, Scotland) graduated from Edinburgh University and then lectured in Physics. He was appointed Professor of Physics at Queen's College Dundee and held this post for 37 years. He was a founder member of the EMS and became President in 1895 and 1932. *SAU
