An airport is an aerodrome with facilities for flights to take off and land. Airports often have facilities to store and maintain aircraft, and a control tower. An airport consists of a landing area, which comprises an aerially accessible open space including at least one operationally active surface such as a runway for a plane to take off or a helipad, and often includes adjacent utility buildings such as control towers, hangars and terminals.
An eponym is a person, a place, or a thing after which or for which someone or something is, or is believed to be, named. Adjectives derived from the word eponym include eponymous and eponymic.
Murphy's law is an adage or epigram that is typically stated as: "Anything that can go wrong will go wrong.".
A syndrome is a set of medical signs and symptoms which are correlated with each other and often associated with a particular disease or disorder. The word derives from the Greek σύνδρομον, meaning "concurrence". When a syndrome is paired with a definite cause this becomes a disease. In some instances, a syndrome is so closely linked with a pathogenesis or cause that the words syndrome, disease, and disorder end up being used interchangeably for them. This substitution of terminology often confuses the reality and meaning of medical diagnoses. This is especially true of inherited syndromes. About one third of all phenotypes that are listed in OMIM are described as dysmorphic, which usually refers to the facial gestalt. For example, Down syndrome, Wolf–Hirschhorn syndrome, and Andersen–Tawil syndrome are disorders with known pathogeneses, so each is more than just a set of signs and symptoms, despite the syndrome nomenclature. In other instances, a syndrome is not specific to only one disease. For example, toxic shock syndrome can be caused by various toxins; another medical syndrome named as premotor syndrome can be caused by various brain lesions; and premenstrual syndrome is not a disease but simply a set of symptoms.
Lists of mathematics topics cover a variety of topics related to mathematics. Some of these lists link to hundreds of articles; some link only to a few. The template to the right includes links to alphabetical lists of all mathematical articles. This article brings together the same content organized in a manner better suited for browsing. Lists cover aspects of basic and advanced mathematics, methodology, mathematical statements, integrals, general concepts, mathematical objects, and reference tables. They also cover equations named after people, societies, mathematicians, journals, and meta-lists.
Stigler's law of eponymy, proposed by University of Chicago statistics professor Stephen Stigler in his 1980 publication "Stigler's law of eponymy", states that no scientific discovery is named after its original discoverer. Examples include Hubble's law, which was derived by Georges Lemaître two years before Edwin Hubble; the Pythagorean theorem, which was known to Babylonian mathematicians before Pythagoras; and Halley's Comet, which was observed by astronomers since at least 240 BC.
Medical eponyms are terms used in medicine which are named after people. In 1975, the Canadian National Institutes of Health held a conference that discussed the naming of diseases and conditions. The conclusion, as summarized in The Lancet, was this: "The possessive use of an eponym should be discontinued, since the author neither had nor owned the disorder."
In the history of Assyria, the eponym dating system was a calendar system for Assyria, for a period of over one thousand years. Every year was associated with the name, an eponym, of the Limmu, the official who led that year's New Year festival.
The Japanese red-backed vole, Wakayama red-backed vole, or Anderson's red-backed vole is a species of rodent in the family Cricetidae. It is found only on the island of Honshu in Japan. It was first described by the British zoologist Oldfield Thomas in 1905. Thomas named it in honor of scientific collector Malcolm Playfair Anderson. The International Union for Conservation of Nature lists it as "least concern".
Keppel Harcourt Barnard was a South African zoologist and museum director. He was the only son of Harcourt George Barnard, a solicitor from Lambeth, and Anne Elizabeth Porter of Royston.
Bird Names for Birds is a campaign to change the common names of American birds named after people, and to redress the recognition in ornithology of figures with racist or colonial pasts. Launched in June 2020 by ornithologists Jordan E. Rutter and Gabriel Foley with a public petition, in the midst of the George Floyd protests and in the aftermath of an incident in Central Park that paved the way to Black Birders Week, the movement emerged after several years of social activism by multiple American ornithologists and birders, many of whom are not affiliated with Bird Names for Birds but remain devoted to the cause. The inaugural petition, dated June 22, 2020, and co-signed by 182 individuals, urged the American Ornithological Society (AOS) to "acknowledge the issue of eponymous and honorific common names, to outline a plan to change harmful common names, and to prioritize the implementation of this plan". In 2023, the AOS formally announced that it would change all English-language bird names that are named directly after people.
