Contronym. A contronym is a word with two opposite meanings; such a word is also known as an antagonym, autoantonym, contranym, or Janus word. [ 1][ 2] For example, the word cleave can mean "to cut apart" or "to bind together". This feature is also called enantiosemy, [ 3][ 4] enantionymy ( enantio- means "opposite"), antilogy or autoantonymy.
As a response to an unlikely proposition, "when pigs fly", "when pigs have wings", or simply "pigs might fly".[1]"When Hell freezes over" [2] and "on a cold day in Hell" [3] are based on the understanding that Hell is eternally an extremely hot place.
Mutations can involve the duplication of large sections of DNA, usually through genetic recombination. [ 9] These duplications are a major source of raw material for evolving new genes, with tens to hundreds of genes duplicated in animal genomes every million years. [ 10] Most genes belong to larger gene families of shared ancestry, detectable ...
Aphantasia ( / ˌeɪfænˈteɪʒə / AY-fan-TAY-zhə, / ˌæfænˈteɪʒə / AF-an-TAY-zhə) is the inability to visualize. [ 1] The phenomenon was first described by Francis Galton in 1880, [ 2] but has remained relatively unstudied. Interest in the phenomenon renewed after the publication of a study in 2015 conducted by a team led by Adam ...
The expected utility of the above bet (with a 50% chance of receiving 100 and a 50% chance of receiving 0) is = (() + ()) /, and if the person has the utility function with u(0)=0, u(40)=5, and u(100)=10 then the expected utility of the bet equals 5, which is the same as the known utility of the amount 40. Hence the certainty equivalent is 40.
Willard Gibbs, Graphical Methods in the Thermodynamics of Fluids The concept of entropy is described by two principal approaches, the macroscopic perspective of classical thermodynamics, and the microscopic description central to statistical mechanics. The classical approach defines entropy in terms of macroscopically measurable physical properties, such as bulk mass, volume, pressure, and ...
The term "serendipity" is often applied to inventions made by chance rather than intent. Andrew Smith, editor of The Oxford Companion to American Food and Drink, has speculated that most everyday products had serendipitous roots, with many early ones related to animals. The origin of cheese, for example, possibly originated in the nomad ...
Opposite (semantics) In lexical semantics, opposites are words lying in an inherently incompatible binary relationship. For example, something that is male entails that it is not female. It is referred to as a 'binary' relationship because there are two members in a set of opposites. The relationship between opposites is known as opposition.
