Wilhelm Lenz

Wilhelm Lenz ( born February 8, 1888 in Frankfurt am Main, Bock Home, † April 30, 1957 in Hamburg ) was a German physicist and taught at the University of Hamburg.

Life

Wilhelm Lenz studied after attending the secondary school physics and mathematics at the universities of Göttingen ( 1906-08 ) and Munich ( 1908-11 ). It was founded in 1911 by Arnold Sommerfeld in Munich doctorate ( About the alternating electromagnetic field of the coil and the AC resistance, inductance and capacitance ) and was then until 1920 his assistant. During the First World War he served as a radio operator at the front in northern France. The reputation as ao. Professor of Theoretical Physics at the University of Rostock in 1920 followed a year later, the Ordinariate of the new University of Hamburg until 1956. Together with Otto Stern built Lenz in Hamburg a center of nuclear physics in close scientific contact with Munich ( Sommerfeld), Göttingen ( Max Born and James Franck ) and Copenhagen ( Niels Bohr) on. His assistants were in 1922 Wolfgang Pauli, later, Walter Gordon ( 1927), Pascual Jordan (1927) and Albrecht Unsold ( 1930). He was succeeded by Harry Lehmann ( 1956).

Lenz signed in November 1933, the commitment of the professors at German universities and colleges to Adolf Hitler.

During his studies he became a member of the country team Cimbria Göttingen.

His doctoral include Johannes Hans Daniel Jensen, Ernst Ising, Hans -Jürgen Borchers and Lucie Mensing.

Services

In 1920 he led to the declaration of paramagnetic properties of a solid body umklapp processes. Reflections on the pressure broadening of the spectral lines employed him in the context of quantum mechanics. He researched the balance between radiation and matter in Einstein's " static ", closed, matter- filled cosmological model (1926 ), on issues of gas degeneracy (1929, 1938), the theory of ion lattice (1932 ) and produced by ships water waves (1947). He succeeded in solving the problem of the hydrogen atom in crossed fields by introducing the Runge -Lenz vector.

He is also co-inventor of the Ising model, whose doctoral thesis ( 1924) about the model he suggested. He also published in 1920 ..
