Wilhelm Robert Karl Anderson (28 October [ O.S. 16 October] 1880 – 26 March 1940) was a Russian-Estonian astrophysicist of Baltic German descent who studied the physical structure of the stars.

Life

Wilhelm Anderson was born in Minsk (now in Belarus) into a Baltic German family. [1] His younger brothers were the well known mathematician Oskar Anderson (1887–1960) and the folklorist Walter Anderson (1885–1962). Anderson spent some of his youth in Kazan, where his father Nikolai Anderson (1845–1905) was a university professor for Finno-Ugric languages. [2]

He studied at the University of Kazan, where he graduated from the department of mathematics and science in 1909. Between 1910 and 1920, he worked as a physics teacher first in Samara and then from 1918 in Minsk. [3] Together with his brother Walter Anderson, he moved to Tartu (Estonia) in 1920. At the University of Tartu, he first gained a Masters degree in Astronomy in 1923 and then a Doctorate in 1927. [4] In 1934 he became a habilitation candidate at the university, and in 1936 he received an assistant professorship there, but early in 1939 he suffered a mental breakdown which left him unable to work. [1] . Like the majority of Baltic Germans, he was resettled to Germany in late 1939, where he died in the Sanatorium of Meseritz-Obrawalde, shortly thereafter. It has been suggested that Anderson may have been a victim of the National Socialist "euthanasia" program. [1]

Anderson is probably best known for his work on the mass limit for a white dwarf (one of the final evolutionary states of a star), [5] extending Edmund Stoner's earlier work [6] by relativistic amplification (1929, Tartu), [7] [8] [1] which was in turn further improved by Stoner. [9] [10] The Stoner-Anderson equation of state, a result of Anderson's correspondence with Stoner, is named after him. [11] The white dwarf mass limit was further refined by Subrahmanyan Chandrasekhar and is now known as the Chandrasekhar limit. [12] [9]

The Chandrasekhar limit is the maximum mass of a stable white dwarf star. The currently accepted value of the Chandrasekhar limit is about 1.4 M (2.765×1030 kg).

Werner Heisenberg German theoretical physicist

Werner Karl Heisenberg was a German theoretical physicist and one of the key pioneers of quantum mechanics. He published his work in 1925 in a breakthrough paper. In the subsequent series of papers with Max Born and Pascual Jordan, during the same year, this matrix formulation of quantum mechanics was substantially elaborated. He is known for the Heisenberg uncertainty principle, which he published in 1927. Heisenberg was awarded the 1932 Nobel Prize in Physics "for the creation of quantum mechanics".

Wilhelm Wien German physicist

Wilhelm Carl Werner Otto Fritz Franz Wien was a German physicist who, in 1893, used theories about heat and electromagnetism to deduce Wien's displacement law, which calculates the emission of a blackbody at any temperature from the emission at any one reference temperature.

<i>Annalen der Physik</i> German physics journal

Annalen der Physik is one of the oldest scientific journals on physics and has been published since 1799. The journal publishes original, peer-reviewed papers in the areas of experimental, theoretical, applied, and mathematical physics and related areas. The current editor-in-chief is Stefan Hildebrandt. Prior to 2008, its ISO 4 abbreviation was Ann. Phys. (Leipzig), and after 2008 Ann. Phys. (Berl.).

Magnon physics term

A magnon is a quasiparticle, a collective excitation of the electrons' spin structure in a crystal lattice. In the equivalent wave picture of quantum mechanics, a magnon can be viewed as a quantized spin wave. Magnons carry a fixed amount of energy and lattice momentum, and are spin-1, indicating they obey boson behavior.

Pascual Jordan German physicist and politician

Ernst Pascual Jordan was a German theoretical and mathematical physicist who made significant contributions to quantum mechanics and quantum field theory. He contributed much to the mathematical form of matrix mechanics, and developed canonical anticommutation relations for fermions. Jordan algebra is employed for and is still used in studying the mathematical and conceptual foundations of quantum theory, and has found other mathematical applications.

Walter Friedrich Karl Weizel was a German theoretical physicist and politician. As a result of his opposition to National Socialism in Germany, he was forced into early retirement for a short duration in 1933. He was a full at the University of Bonn, from 1936 to 1969. After World War II, he helped to establish the Jülich Research Center, and he was a state representative of the Social Democratic Party of Germany.

Zeitschrift für Physik is a defunct series of German peer-reviewed German scientific journal of physics established in 1920 by Springer Berlin Heidelberg. The series stopped publication in 1997, when they merged with other journals to form the new European Physical Journal series. It had grown to four parts over the years.

The Hanle effect, also known as zero-field level crossing, is a reduction in the polarization of light when the atoms emitting the light are subject to a magnetic field in a particular direction, and when they have themselves been excited by polarized light.

Fritz Weigert was a German physical chemist. Weigert has made major contributions in the field of photochemistry. He was born in Berlin. He was the nephew of both Karl Weigert and Paul Ehrlich. He was married to Margarete Behmer. Around 1908, he began teaching and conducting research at Berlin University - after studying there. He was a photochemistry professor at Leipzig University from 1914 until being forced out by the Nazis in 1934. On January 1st, 1935, he immigrated to England and in 1936 was director of the Physiochemical Department of the Cancer Research Institute at Mount Vernon Hospital, Northwood.

Myron Mathisson was a theoretical physicist of Polish and Jewish descent. He is known for his work in general relativity, for developing a new method to analyze the properties of fundamental solutions of linear hyperbolic partial differential equations, and proved, in a special case, the Hadamard conjecture on the class of equations that satisfy the Huygens principle.
