Lucy Mensing
Lucy Mensing (also Lucie), later Mensing-Schütz or Schütz, (11 March 1901 - 28 April 1995) was a German physicist and a pioneer of quantum mechanics. Scientific career Mensing studied mathematics, physics and chemistry at the University of Hamburg. During her studies she specialized in theoretical physics. In 1923/24 she wrote a thesis in which she applied the older quantum hypothesis based on Bohr-Sommerfeld's theory, which assumes electron trajectories, to diatomic molecules. This work was published in the Zeitschrift für Physik in 1925. In 1925 she received her doctorate under Wilhelm Lenz with a thesis on the influence of electric fields on the width of spectral lines. After her doctorate, she got the opportunity to come to Göttingen and take part in the development of quantum mechanics, where she was advised by Pascual Jordan. She studied the rotational spectrum of diatomic molecules using the methods of matrix mechanics. After Wolfgang Pauli's treatment of the hydroge ...

Quantum Mechanics
Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles. It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science. Classical physics, the collection of theories that existed before the advent of quantum mechanics, describes many aspects of nature at an ordinary (macroscopic) scale, but is not sufficient for describing them at small (atomic and subatomic) scales. Most theories in classical physics can be derived from quantum mechanics as an approximation valid at large (macroscopic) scale. Quantum mechanics differs from classical physics in that energy, momentum, angular momentum, and other quantities of a bound system are restricted to discrete values ( quantization); objects have characteristics of both particles and waves (wave–particle duality); and there are limits to ...

Helmut Rechenberg
Helmut Rechenberg (born November 6, 1937, in Berlin; died November 10, 2016, in Munich) was a German physicist and science historian. Rechenberg studied mathematics, physics and astronomy at the University of Munich and graduated in 1964. At Munich, his work was in experimental physics, studying the magnetism of solids. He moved to the Max Planck Institute for Physics in Munich, where he became Werner Heisenberg's doctoral student. In 1968, he graduated with a doctorate on quantum field theory. From 1970 to 1972 he worked at the University of Texas at Austin, collaborating with George Sudarshan on quantum field theory and with Jagdish Mehra on science history. He then returned to Germany and the Max Planck Institute, from which he officially retired in 2002. His six-volume work with Jagdish Mehra on the history of quantum mechanics has been described as "an extraordinary amount of painstaking scholarship". Rechenberg also co-edited Werner Heisenberg's collected works and from 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Operation Osoaviakhim
Operation Osoaviakhim () was a secret Soviet operation under which more than 2,500 former Nazi German specialists (; i.e. scientists, engineers and technicians who worked in specialist areas) from companies and institutions relevant to military and economic policy in the Soviet occupation zone of Germany (SBZ) and the Soviet sector of Berlin, as well as around 4,000 more family members, totalling more than 6,000 people, were transported from former Nazi Germany as war reparations in the Soviet Union. It took place in the early morning hours of October 22, 1946 when MVD (previously NKVD) and Soviet Army units under the direction of the Soviet Military Administration in Germany (SMAD), headed by Ivan Serov. Much related equipment was also moved, the aim being to literally transplant research and production research centers such as the relocated V-2 rocket center of Mittelwerk, from Germany to the Soviet Union, and collect as much material as possible from test centers such as the ...
