Walther Nernst
Walther Hermann Nernst (; 25 June 1864 – 18 November 1941) was a German physical chemist known for his work in thermodynamics, physical chemistry, electrochemistry, and solid-state physics. His formulation of the Nernst heat theorem helped pave the way for the third law of thermodynamics, for which he won the 1920 Nobel Prize in Chemistry. He is also known for developing the Nernst equation in 1887. He studied physics and mathematics at the universities of Zürich, Berlin, Graz and Würzburg, where he received his doctorate 1887. In 1889, he finished his habilitation at University of Leipzig. Life and career Early years Nernst was born in Briesen, Germany (now Wąbrzeźno, Poland) to Gustav Nernst (1827–1888) and Ottilie Nerger (1833–1876). His father was a country judge. Nernst had three older sisters and one younger brother. His third sister died of cholera. Nernst went to elementary school at Graudenz, Germany (now Grudziądz, Poland). Studies Nernst started ...

Ludwig Boltzmann
Ludwig Eduard Boltzmann ( ; ; 20 February 1844 – 5 September 1906) was an Austrian mathematician and Theoretical physics, theoretical physicist. His greatest achievements were the development of statistical mechanics and the statistical explanation of the second law of thermodynamics. In 1877 he provided the current definition of entropy, S = k_ \ln \Omega, where Ω is the number of microstates whose energy equals the system's energy, interpreted as a measure of the statistical disorder of a system. Max Planck named the constant the Boltzmann constant. Statistical mechanics is one of the pillars of modern physics. It describes how macroscopic observations (such as temperature and pressure) are related to microscopic parameters that fluctuate around an average. It connects thermodynamic quantities (such as heat capacity) to microscopic behavior, whereas, in classical thermodynamics, the only available option would be to measure and tabulate such quantities for various mat ...

Robert Von Lieben
Robert von Lieben (September 5, 1878, in Vienna – February 20, 1913, in Vienna) was an Austrian entrepreneur, and self-taught physicist and inventor. Lieben and his associates Eugen Reisz and Siegmund Strauss invented and produced a gas-filled triode – the first thermionic valve with a control grid that was designed specifically for electronic amplifier, amplification rather than demodulation of signals, and is a distant ancestor of the thyratron. After Lieben's death, the "Lieben valve", which is also known in English as the "Lieben-Reisz valve" and in German as the "LRS-Relais" (Lieben-Reisz-Strauss relay), was used in the world's first continuous wave radio frequency generator designed for Radiotelephone, radio telephony. Biography Robert von Lieben was the fourth of five children born into a wealthy History of the Jews in Vienna, Viennese Jewish family who were related to the Auspitz, Gomperz, Todesco and Wertheimstein clans. His father Leopold von Lieben man ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Max Bodenstein
Max Ernst August Bodenstein (July 15, 1871 – September 3, 1942) was a German physical chemist known for his work in chemical kinetics. He was first to postulate a chain reaction mechanism and that explosions are branched chain reactions, later applied to the atomic bomb. Early life Max Bodenstein was born in Magdeburg on 15 July 1871 as the eldest son of Magdeburg merchant and brewer Franz Bodenstein (1834–1885) and his first wife Elise Meissner (1846–1876). Education In 1888, Max Bodenstein enrolled at the University of Heidelberg at the age of 17 to study chemistry with Carl Remigius Fresenius. On 25 October 1893, he received his PhD thesis: "''Über die Zersetzung des Jodwasserstoffes in der Hitze''" (On the degradation of hydrogen iodide in hot temperature), with Victor Meyer as his supervisor at the University of Heidelberg. Following graduation, Bodenstein received two years of additional training in Berlin-Charlottenburg and Göttingen. Bodenstein studied organic ...

Arnold Eucken
Arnold Thomas Eucken (; 3 July 1884 – 16 June 1950) was a German chemist and physicist. He is known for his contribution to thermodynamics and molecular physics, in particular, for the discovery of Eucken's law of thermal conductivity, the measurement of the heat capacity of hydrogen at low temperatures, and the development of the Eucken–Polanyi potential theory of adsorption.

Frederick Lindemann, 1st Viscount Cherwell
Frederick Alexander Lindemann, 1st Viscount Cherwell, ( ; 5 April 18863 July 1957) was a British physicist who was prime scientific adviser to Winston Churchill in World War II. He was involved in the development of radar and infra-red guidance systems. He was sceptical of the first reports of the enemy's V-weapons programme. He pressed the case for the strategic area bombing of cities. His abiding influence on Churchill stemmed from close personal friendship, as a member of the latter's country-house set. In Churchill's second government, he was given a seat in the cabinet, and later created Viscount Cherwell of Oxford. Early life, family and personality Lindemann was the second of three sons of Adolph Friedrich Lindemann, who had emigrated to the United Kingdom circa 1871 and became naturalised. – See especially p. 343.
