Discovery is the act of detecting something new, or something previously unrecognized as meaningful, "portal". In sciences and academic disciplines, discovery is the observation of new phenomena, new actions, or new events and involves providing new reasoning to explain the knowledge gathered through such observations, using knowledge previously acquired through abstract thought and from ...
Response surface: A designed experiment that models the quantitative response, especially for the short-term goal of improving a process and the longer-term goal of finding optimum factor-values. Traditionally, response-surfaces have been modeled with quadratic-polynomials, whose estimation requires that every factor have three levels.
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
Robert K. Merton defined such "multiples" as instances in which similar discoveries are made by scientists working independently of each other. [1] "Sometimes", writes Merton, "the discoveries are simultaneous or almost so; sometimes a scientist will make a new discovery which, unknown to him, somebody else has made years before." [2]

Time-independent plastic flow in both single crystals and polycrystals is defined by a critical/maximum resolved shear stress (τ CRSS), initiating dislocation migration along parallel slip planes of a single slip system, thereby defining the transition from elastic to plastic deformation behavior in crystalline materials.
“The only answer to plastic pollution is to reduce the amount of plastics entering the environment,” a State College resident writes. Letters: Finding solutions to the plastic problem; Take ...
In the modern era, cheaper plastic items often attempt to mimic more expensive wooden and metal products, [16] though they are only skeuomorphic if new ornamentation references the original functionality, [17] such as molded screw heads in molded plastic items. Another well-known skeuomorph is the plastic Adirondack chair. [18]
