Elias Gyftopoulos
Elias Panayiotis Gyftopoulos (; July 4, 1927June 23, 2012) was a Greek-American engineer who contributed to thermodynamics both in its general formulation and its quantum foundations. Gyftopoulos received an undergraduate degree in mechanical and electrical engineering in 1953 at the National Technical University of Athens, and a Doctor of Science degree in electrical engineering at the Massachusetts Institute of Technology in 1958. At MIT, he initially focused on nuclear reactor safety and control. After meeting professors George N. Hatsopoulos and Joseph H. Keenan, ISBN 9780471359999 his interests moved towards thermodynamics, in an attempt to give a consistent and rigorous exposition, free of the logical flaws and the limitations commonly associated with this discipline: his contribution culminated with reference textbook which completely reformulates the foundations of the subject, offering a general non-statistical definition of entropy applicable to both macroscopic and mi ...

MIT School Of Engineering Alumni
The Massachusetts Institute of Technology (MIT) is a private research university in Cambridge, Massachusetts, United States. Established in 1861, MIT has played a significant role in the development of many areas of modern technology and science. In response to the increasing industrialization of the United States, William Barton Rogers organized a school in Boston to create "useful knowledge." Initially funded by a federal land grant, the institute adopted a polytechnic model that stressed laboratory instruction in applied science and engineering. MIT moved from Boston to Cambridge in 1916 and grew rapidly through collaboration with private industry, military branches, and new federal basic research agencies, the formation of which was influenced by MIT faculty like Vannevar Bush. In the late twentieth century, MIT became a leading center for research in computer science, digital technology, artificial intelligence and big science initiatives like the Human Genome Pr ...

Quantum Mechanics
Quantum mechanics is the fundamental physical Scientific theory, theory that describes the behavior of matter and of light; its unusual characteristics typically occur at and below the scale of atoms. Reprinted, Addison-Wesley, 1989, It is the foundation of all quantum physics, which includes quantum chemistry, quantum field theory, quantum technology, and quantum information science. Quantum mechanics can describe many systems that classical physics cannot. Classical physics can describe many aspects of nature at an ordinary (macroscopic and Microscopic scale, (optical) microscopic) scale, but is not sufficient for describing them at very small submicroscopic (atomic and subatomic) scales. Classical mechanics can be derived from quantum mechanics as an approximation that is valid at ordinary scales. Quantum systems have Bound state, bound states that are Quantization (physics), quantized to Discrete mathematics, discrete values of energy, momentum, angular momentum, and ot ...

Quantum Thermodynamics
Quantum thermodynamics is the study of the relations between two independent physical theories: thermodynamics and quantum mechanics. The two independent theories address the physical phenomena of light and matter. In 1905, Albert Einstein argued that the requirement of consistency between thermodynamics and electromagnetism leads to the conclusion that light is quantized, obtaining the relation E= h \nu . This paper is the dawn of quantum theory. In a few decades quantum theory became established with an independent set of rules. Currently quantum thermodynamics addresses the emergence of thermodynamic laws from quantum mechanics. It differs from quantum statistical mechanics in the emphasis on dynamical processes out of equilibrium. In addition, there is a quest for the theory to be relevant for a single individual quantum system. Dynamical view There is an intimate connection of quantum thermodynamics with the theory of open quantum systems. Quantum mechanics inserts dynamics ...

Joseph Henry Keenan
Joseph Henry Keenan (August 24, 1900 – July 17, 1977) was an American thermodynamicist and mechanical engineer noted for his work in the calculation of steam tables, research in jet-rocket propulsion, and his work in furthering the development in the understanding of the laws of thermodynamics in the mid 20th century. His classic 1941 textbook ''Thermodynamics'' served as a fundamental teaching tool in various engineering curricula during the 1940s and 1950s. He earned a bachelor's degree in naval architecture and marine engineering at the Massachusetts Institute of Technology in 1922. After working as a design engineer on steam turbines for General Electric Company, Keenan became an assistant professor of mechanical engineering at the Stevens Institute of Technology in 1928. In 1934, he became an associate professor of mechanical engineering at the Massachusetts Institute of Technology. He was promoted to professor in 1939. He served as Head of the Department of Mechanical En ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Reactor
A nuclear reactor is a device used to initiate and control a Nuclear fission, fission nuclear chain reaction. They are used for Nuclear power, commercial electricity, nuclear marine propulsion, marine propulsion, Weapons-grade plutonium, weapons production and Research reactor, research. Fissile material, Fissile nuclei (primarily uranium-235 or plutonium-239) absorb single neutron, neutrons and split, releasing energy and multiple neutrons, which can induce further fission. Reactors stabilize this, regulating Neutron absorber, neutron absorbers and neutron moderator, moderators in the core. Fuel efficiency is exceptionally high; Enriched uranium#Low-enriched uranium (LEU), low-enriched uranium is 120,000 times more energy dense than coal. Heat from nuclear fission is passed to a working fluid Nuclear reactor#By coolant, coolant. In commercial reactors, this drives Turbine, turbines and electrical generator shafts. Some reactors are used for district heating, and isotopes, isoto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
