Absolute dating is the process of determining an age on a specified chronology in archaeology and geology. Some scientists prefer the terms chronometric or calendar dating, as use of the word "absolute" implies an unwarranted certainty of accuracy. [1] [2] Absolute dating provides a numerical age or range, in contrast with relative dating ...
Category. v. t. e. Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha, beta, and gamma ...
Urban decay (also known as urban rot, urban death or urban blight) is the sociological process by which a previously functioning city, or part of a city, falls into ...
Antiphrasis. Antiphrasis is the rhetorical device of saying the opposite of what is actually meant in such a way that it is obvious what the true intention is. [1] Some authors treat and use antiphrasis just as irony, euphemism or litotes. [2]
Exponential decay is a scalar multiple of the exponential distribution (i.e. the individual lifetime of each object is exponentially distributed), which has a well-known expected value. We can compute it here using integration by parts .
Enshittification. Enshittification is the pattern of decreasing quality observed in online services and products such as Amazon, Facebook, Google Search, Twitter, Bandcamp, Reddit, Uber, and Unity. The term was used by writer Cory Doctorow in November 2022, and the American Dialect Society selected it as its 2023 Word of the Year.
A nuclide (or nucleide, from nucleus, also known as nuclear species) is a class of atoms characterized by their number of protons, Z, their number of neutrons, N, and their nuclear energy state. [1] The word nuclide was coined by the American nuclear physicist Truman P. Kohman in 1947. [2] [3] Kohman defined nuclide as a "species of atom ...
The dominant muon decay mode (sometimes called the Michel decay after Louis Michel) is the simplest possible: the muon decays to an electron, an electron antineutrino, and a muon neutrino. Antimuons, in mirror fashion, most often decay to the corresponding antiparticles: a positron, an electron neutrino, and a muon antineutrino. In formulaic ...
