Otto Stern (; 17 February 1888 – 17 August 1969) was a German-American physicist and Nobel laureate in physics. He was the second most nominated person for a Nobel Prize, with 82 nominations in the years 1925–1945 (most times nominated is Arnold Sommerfeld with 84 nominations), ultimately winning in 1943. Biography Stern was born into a Jewish family in Sohrau (now Żory) in the Province of Silesia, the German Empire's Kingdom of Prussia. His father was Oskar Stern (1850–1919), a mill owner, who had been living in Breslau (now Wrocław) since 1892. His mother Eugenia née Rosenthal (1863–1907) was from Rawitsch (now Rawicz) in the Prussian Province of Posen.

Louise Otto-Peters
Louise Otto-Peters (26 March 1819, Meissen – 13 March 1895, Leipzig) was a German suffragist and women's rights movement activist who wrote novels, poetry, essays, and libretti. She wrote for ''Der Wandelstern'' he Wandering Starand ''Sächsische Vaterlandsblätter'' axon Fatherland Pages and founded ''Frauen-Zeitung'' and ''Neue Bahnen'' specifically for women. She is best known as the founder in 1865 of the General German Women's Association ('' Allgemeiner Deutscher Frauenverein''). Life Louise Otto was born in Meissen, the daughter of Charlotte and Wilhelm Otto, a successful lawyer. She was educated by private tutors. In 1835, when she was 16, both her parents and an older sister died. Otto-Peters thereafter lived with her two older sisters.

She additionally worked as a journalist from 1843 "with articles about her concept of femininity, as well as women and politics". ...

Spin (physics)
Spin is a conserved quantity carried by elementary particles, and thus by composite particles (hadrons) and atomic nucleus, atomic nuclei. Spin is one of two types of angular momentum in quantum mechanics, the other being ''orbital angular momentum''. The orbital angular momentum operator is the quantum-mechanical counterpart to the classical angular momentum of orbital revolution and appears when there is periodic structure to its wavefunction as the angle varies. For photons, spin is the quantum-mechanical counterpart of the Polarization (waves), polarization of light; for electrons, the spin has no classical counterpart. The existence of electron spin angular momentum is inferred from experiments, such as the Stern–Gerlach experiment, in which silver atoms were observed to possess two possible discrete angular momenta despite having no orbital angular momentum. The existence of the electron spin can also be inferred theoretically from the spin–statistics theorem and from th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freiburg Im Breisgau
Freiburg im Breisgau (; abbreviated as Freiburg i. Br. or Freiburg i. B.; Low Alemannic German, Low Alemannic: ''Friburg im Brisgau''), commonly referred to as Freiburg, is an independent city in Baden-Württemberg, Germany.

Province Of Posen
The Province of Posen (german: Provinz Posen, pl, Prowincja Poznańska) was a province of the Kingdom of Prussia from 1848 to 1920. Posen was established in 1848 following the Greater Poland Uprising as a successor to the Grand Duchy of Posen, which in turn was annexed by Prussia in 1815 from Napoleon's Duchy of Warsaw. It became part of the German Empire in 1871. After World War I, Posen was briefly part of the Free State of Prussia within Weimar Germany, but was dissolved in 1920 when most of its territory was ceded to the Second Polish Republic by the Treaty of Versailles, and the remaining German territory was later re-organized into Posen-West Prussia in 1922. Posen (present-day Poznań, Poland) was the provincial capital. Geography The land is mostly flat, drained by two major watershed systems; the Noteć (German: ''Netze'') in the north and the Warta (''Warthe'') in the center. Ice Age glaciers left moraine deposits and the land is speckled with hundreds of "finger l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arnold Sommerfeld
Arnold Johannes Wilhelm Sommerfeld, (; 5 December 1868 – 26 April 1951) was a German theoretical physicist who pioneered developments in atomic and quantum physics, and also educated and mentored many students for the new era of theoretical physics. He served as doctoral supervisor for many Nobel Prize winners in physics and chemistry (only J. J. Thomson's record of mentorship is comparable to his). He introduced the second quantum number (azimuthal quantum number) and the third quantum number (magnetic quantum number). He also introduced the fine-structure constant and pioneered X-ray wave theory. Early life and education Sommerfeld was born in 1868 to a family with deep ancestral roots in Prussia. His mother Cäcilie Matthias (1839–1902) was the daughter of a Potsdam builder. His father Franz Sommerfeld (1820–1906) was a physician from a leading family in Königsberg, where Arnold's grandfather had resettled from the hinterland in 1822 for a career as Court Postal ...
