Max Abraham (German: [ˈaːbʀaham] ; 26 March 1875 – 16 November 1922) was a German physicist. Abraham was born in Danzig, Imperial Germany (now Gdańsk in Poland) to a family of Jewish merchants. His father was Moritz Abraham and his mother was Selma Moritzsohn. Attending the University of Berlin, he studied under Max Planck. He graduated in 1897. For the next three years, Abraham worked as Planck's assistant.[ citation needed ].
From 1900 to 1909, Abraham worked at Göttingen as a privatdozent, an unpaid lecturing position.
Abraham developed his theory of the electron in 1902, in which he hypothesized that the electron was a perfect sphere with a charge divided evenly around its surface. Abraham's model was competing with that developed by Hendrik Lorentz (1899, 1904) and Albert Einstein (1905) which seem to have become more widely accepted; nevertheless, Abraham never gave up his model, since he considered it was based on "common sense".
In 1909 Abraham travelled to the United States to accept a position at the University of Illinois, but ended up returning to Göttingen after a few months. He was later invited to Italy by Tullio Levi-Civita, and found work as the professor of rational mechanics at the Politecnico di Milano university until 1914.
When World War I started, Abraham was forced to return to Germany. During this time he worked on the theory of radio transmission. After the war, he still was not allowed back into Milan, so until 1921 he worked at Stuttgart as the professor of physics at Technische Hochschule.
After his work at Stuttgart, Abraham accepted the position of chair in Aachen; however, before he started his work there he was diagnosed with a brain tumor. He died on 16 November 1922 in Munich, Germany.
After his death, Max Born and Max von Laue wrote about him in an obituary: He loved his absolute aether, his field equations, his rigid electron just as a youth loves his first flame, whose memory no later experience can extinguish.
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.
Friedrich Hermann Hund was a German physicist from Karlsruhe known for his work on atoms and molecules.
Eduard Study, more properly Christian Hugo Eduard Study, was a German mathematician known for work on invariant theory of ternary forms (1889) and for the study of spherical trigonometry. He is also known for contributions to space geometry, hypercomplex numbers, and criticism of early physical chemistry.
Gustav Adolf Feodor Wilhelm Ludwig Mie was a German physicist.
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.).
Adolf Kneser was a German mathematician.
Friedrich Hasenöhrl, was an Austrian physicist.
The history of special relativity consists of many theoretical results and empirical findings obtained by Albert A. Michelson, Hendrik Lorentz, Henri Poincaré and others. It culminated in the theory of special relativity proposed by Albert Einstein and subsequent work of Max Planck, Hermann Minkowski and others.
Electromagnetic mass was initially a concept of classical mechanics, denoting as to how much the electromagnetic field, or the self-energy, is contributing to the mass of charged particles. It was first derived by J. J. Thomson in 1881 and was for some time also considered as a dynamical explanation of inertial mass per se. Today, the relation of mass, momentum, velocity, and all forms of energy – including electromagnetic energy – is analyzed on the basis of Albert Einstein's special relativity and mass–energy equivalence. As to the cause of mass of elementary particles, the Higgs mechanism in the framework of the relativistic Standard Model is currently used. In addition, some problems concerning the electromagnetic mass and self-energy of charged particles are still studied.
The Kaufmann–Bucherer–Neumann experiments measured the dependence of the inertial mass of an object on its velocity. The historical importance of this series of experiments performed by various physicists between 1901 and 1915 is due to the results being used to test the predictions of special relativity. The developing precision and data analysis of these experiments and the resulting influence on theoretical physics during those years is still a topic of active historical discussion, since the early experimental results at first contradicted Einstein's then newly published theory, but later versions of this experiment confirmed it. For modern experiments of that kind, see Tests of relativistic energy and momentum, for general information see Tests of special relativity.
Gustav Herglotz was a German Bohemian physicist. He is best known for his works on the theory of relativity and seismology.
Fritz Eduard Josef Maria Sauter was an Austrian-German physicist who worked mostly in quantum electrodynamics and solid-state physics.
Richard Becker was a German theoretical physicist who made contributions in thermodynamics, statistical mechanics, superconductivity, and quantum electrodynamics.
Kurd Friedrich Rudolf von Mosengeil, also Curd Friedrich Rudolf von Mosengeil, was a German physicist.
Jakob Johann Laub was a physicist from Austria-Hungary, who is best known for his work with Albert Einstein in the early period of special relativity.
Alfred Heinrich Bucherer was a German physicist, who is known for his experiments on relativistic mass. He also was the first who used the phrase "theory of relativity" for Einstein's theory of special relativity.
Vladimir Sergeyevitch Ignatowski, or Waldemar Sergius von Ignatowsky and similar names in other publications, was a Russian physicist.
In physics, a quantum is the minimum amount of any physical entity involved in an interaction. The fundamental notion that a physical property can be "quantized" is referred to as "the hypothesis of quantization". This means that the magnitude of the physical property can take on only discrete values consisting of integer multiples of one quantum.
