https://en.wikipedia.org/wiki/Numbers%20in%20Egyptian%20mythology | Certain numbers were considered sacred, holy, or magical by the ancient Egyptians, particularly 2, 3, 4, 7, and their multiples and sums.
Three: symbol of plurality
The basic symbol for plurality among the ancient Egyptians was the number three: even the way they wrote the word for "plurality" in hieroglyphics consist... |
https://en.wikipedia.org/wiki/Symmetric%20equilibrium | In game theory, a symmetric equilibrium is an equilibrium where all players use the same strategy (possibly mixed) in the equilibrium. In the Prisoner's Dilemma game pictured to the right, the only Nash equilibrium is (D, D). Since both players use the same strategy, the equilibrium is symmetric.
Symmetric equilibri... |
https://en.wikipedia.org/wiki/DPLL%20algorithm | In logic and computer science, the Davis–Putnam–Logemann–Loveland (DPLL) algorithm is a complete, backtracking-based search algorithm for deciding the satisfiability of propositional logic formulae in conjunctive normal form, i.e. for solving the CNF-SAT problem.
It was introduced in 1961 by Martin Davis, George Logem... |
https://en.wikipedia.org/wiki/X-ray%20absorption%20spectroscopy | X-ray absorption spectroscopy (XAS) is a widely used technique for determining the local geometric and/or electronic structure of matter. The experiment is usually performed at synchrotron radiation facilities, which provide intense and tunable X-ray beams. Samples can be in the gas phase, solutions, or solids.

https://en.wikipedia.org/wiki/American%20National%20Corpus | The American National Corpus (ANC) is a text corpus of American English containing 22 million words of written and spoken data produced since 1990. Currently, the ANC includes a range of genres, including emerging genres such as email, tweets, and web data that are not included in earlier corpora such as the British N... |
https://en.wikipedia.org/wiki/Turbo%20Dispatch | Turbo Dispatch is a public domain standard for the electronic transfer of job details, initially using packet radio, but now also using the internet. It is used throughout the United Kingdom to pass the details of stranded motorists between all the major UK motoring organisations and their 400 plus vehicle recovery age... |
https://en.wikipedia.org/wiki/Articulated%20robot | An articulated robot is a robot with rotary joints (e.g. a legged robot or an industrial robot). Articulated robots can range from simple two-jointed structures to systems with 10 or more interacting joints and materials.
They are powered by a variety of means, including electric motors.
Some types of robots, such as... |
https://en.wikipedia.org/wiki/Thermodynamic%20state | In thermodynamics, a thermodynamic state of a system is its condition at a specific time; that is, fully identified by values of a suitable set of parameters known as state variables, state parameters or thermodynamic variables. Once such a set of values of thermodynamic variables has been specified for a system, the v... |
https://en.wikipedia.org/wiki/Biological%20thermodynamics | Biological thermodynamics (Thermodynamics of biological systems) is a science that explains the nature and general laws of thermodynamic processes occurring in living organisms as nonequilibrium thermodynamic systems that convert the energy of the Sun and food into other types of energy. The nonequilibrium thermodynami... |
https://en.wikipedia.org/wiki/Synergetics%20%28Haken%29 | Synergetics is an interdisciplinary science explaining the formation and self-organization of patterns and structures in open systems far from thermodynamic equilibrium. It is founded by Hermann Haken, inspired by the laser theory. Haken's interpretation of the laser principles as self-organization of non-equilibrium s... |
https://en.wikipedia.org/wiki/Quasi-invariant%20measure | In mathematics, a quasi-invariant measure μ with respect to a transformation T, from a measure space X to itself, is a measure which, roughly speaking, is multiplied by a numerical function of T. An important class of examples occurs when X is a smooth manifold M, T is a diffeomorphism of M, and μ is any measure that l... |
