Georg Joos ( 25.05. 1894 - 20.05.1959); full professor for experimental physics at Technical University of Munich. Georg Jakob Christof Joos (25 May 1894 in Bad Urach, German Empire – 20 May 1959 in Munich, West Germany) was a German experimental physicist.
By producing high-resolution diffraction gratings in a basement room at Zeiss, Franz Meyer came into contact with Georg Joos, who had been a professor of theoretical physics at the University of Jena since 1924. Joos wanted to experimentally prove that Einstein's theory of relativity was exactly valid despite apparently contradictory results.
The Vienna Ab initio Simulation Package, better known as VASP, is a package written primarily in Fortran for performing ab initio quantum mechanical calculations using either Vanderbilt pseudopotentials, or the projector augmented wave method, and a plane wave basis set. [2]
Theoretical physics is a branch of physics that employs mathematical models and abstractions of physical objects and systems to rationalize, explain, and predict natural phenomena. This is in contrast to experimental physics , which uses experimental tools to probe these phenomena.
Lectures on Theoretical Physics is a six-volume series of physics textbooks translated from Arnold Sommerfeld's classic German texts Vorlesungen über Theoretische Physik. The series includes the volumes Mechanics , Mechanics of Deformable Bodies , Electrodynamics , Optics , Thermodynamics and Statistical Mechanics , and Partial Differential ...
For example, Georg Joos reprised Miller's experiment using a very similar setup (the arms of his interferometer were 21 m vs. the 32 m in the Miller experiment) and obtained results that were 1/50 the magnitude of those from Miller's (see Michelson–Morley experiment#Subsequent experiments).
After this, informal work began at the Georg-August University of Göttingen by Joos, Hanle, and their colleague Reinhold Mannkopff. Formally the group of physicists was known as the Arbeitsgemeinschaft für Kernphysik (Nuclear Physics Association). This initial work at Göttingen lasted until the fall of 1939, when Joos and Hanle were drafted ...
He was born in Magheragall in County Antrim, the son of Hugh Larmor, a Belfast shopkeeper and his wife, Anna Wright. [3] The family moved to Belfast circa 1860, and he was educated at the Royal Belfast Academical Institution, and then studied mathematics and experimental science at Queen's College, Belfast (BA 1874, MA 1875), [4] where one of his teachers was John Purser.
