Thermal equilibrium

Two physical systems are in thermal equilibrium if there is no net flow of thermal energy between them when they are connected by a path permeable to heat. Thermal equilibrium obeys the zeroth law of thermodynamics. A system is said to be in thermal equilibrium with itself if the temperature within the system is spatially uniform and temporally constant.

Systems in thermodynamic equilibrium are always in thermal equilibrium, but the converse is not always true. If the connection between the systems allows transfer of energy as ‘change in internal energy‘ but does not allow transfer of matter or transfer of energy as work, the two systems may reach thermal equilibrium without reaching thermodynamic equilibrium.

Wilhelm Wien

Wilhelm Carl Werner Otto Fritz Franz Wien (German pronunciation: [ˈvɪlhɛlm ˈviːn] (listen); 13 January 1864 – 30 August 1928) was a German physicist who, in 1893, used theories about heat and electromagnetism to deduce Wien’s displacement law, which calculates the emission of a blackbody at any temperature from the emission at any one reference temperature.

He also formulated an expression for the black-body radiation, which is correct in the photon-gas limit. His arguments were based on the notion of adiabatic invariance, and were instrumental for the formulation of quantum mechanics. Wien received the 1911 Nobel Prize for his work on heat radiation.

He was a cousin of Max Wien, inventor of the Wien bridge.

Frank Wilczek

Frank Anthony Wilczek (/ˈwɪltʃɛk/; born May 15, 1951) is an American theoretical physicistmathematician and Nobel laureate. He is currently the Herman Feshbach Professor of Physics at the Massachusetts Institute of Technology (MIT), Founding Director of T. D. Lee Institute and Chief Scientist at the Wilczek Quantum Center, Shanghai Jiao Tong University (SJTU), distinguished professor at Arizona State University (ASU) and full professor at Stockholm University.

Wilczek, along with David Gross and H. David Politzer, was awarded the Nobel Prize in Physics in 2004 “for the discovery of asymptotic freedom in the theory of the strong interaction“. In May 2022, he was awarded the Templeton Prize for Progress Toward Research or Discoveries about Spiritual Realities.

David Bohm

David Joseph Bohm FRS (/boʊm/; 20 December 1917 – 27 October 1992) was an American-Brazilian-British scientist who has been described as one of the most significant theoretical physicists of the 20th century and who contributed unorthodox ideas to quantum theory, neuropsychology and the philosophy of mind. Among his many contributions to physics is his causal and deterministic interpretation of quantum theory, now known as De Broglie–Bohm theory.

Bohm advanced the view that quantum physics meant that the old Cartesian model of reality—that there are two kinds of substance, the mental and the physical, that somehow interact—was too limited. To complement it, he developed a mathematical and physical theory of “implicate” and “explicate” order. He also believed that the brain, at the cellular level, works according to the mathematics of some quantum effects, and postulated that thought is distributed and non-localised just as quantum entities are. Bohm’s main concern was with understanding the nature of reality in general and of consciousness in particular as a coherent whole, which according to Bohm is never static or complete.

Bohm warned of the dangers of rampant reason and technology, advocating instead the need for genuine supportive dialogue, which he claimed could broaden and unify conflicting and troublesome divisions in the social world. In this, his epistemology mirrored his ontology.

Born in the United States, Bohm obtained his Ph.D. under J. Robert Oppenheimer at the University of California, Berkeley. Due to his Communist affiliations, he was the subject of a federal government investigation in 1949, prompting him to leave the U.S. He pursued his career in several countries, becoming first a Brazilian and then a British citizen. He abandoned Marxism in the wake of the Hungarian Uprising in 1956.

Grete Hermann

Grete Hermann (2 March 1901 – 15 April 1984) was a German mathematician and philosopher noted for her work in mathematics, physics, philosophy and education. She is noted for her early philosophical work on the foundations of quantum mechanics, and is now known most of all for an early, but long-ignored critique of a “no hidden-variables theorem” by John von Neumann. It has been suggested that, had her critique not remained nearly unknown for decades, the historical development of quantum mechanics might have been very different.
