1890 | https://en.wikipedia.org/wiki/American%20English | American English | American English (AmE, AE, AmEng, USEng, en-US), sometimes called United States English or U.S. English, is the set of varieties of the English language native to the United States. English is the most widely spoken language in the United States and in most circumstances is the de facto common language used in government, education, and commerce. Currently, American English is the most influential form of English worldwide. |
1893 | https://en.wikipedia.org/wiki/Albert%20Spalding | Albert Spalding | Albert Goodwill Spalding (September 2, 1849 – September 9, 1915) was an American pitcher, manager, and executive in the early years of professional baseball, and the co-founder of A.G. Spalding sporting goods company. He was born and raised in Byron, Illinois yet graduated from Rockford Central High School in Rockford, Illinois. He played major league baseball between 1871 and 1878. Spalding set a trend when he started wearing a baseball glove. |
1894 | https://en.wikipedia.org/wiki/Africa%20Alphabet | Africa Alphabet | The Africa Alphabet (also International African Alphabet or IAI alphabet) was developed by the International Institute of African Languages and Cultures in 1928, with the help of some Africans led by Diedrich Hermann Westermann, who served as director of the organization from 1926 until 1939. Meanwhile, the aim of the International Institute of African Languages and Cultures, later known as International African Institute (IAI), was to enable people to write all the African languages for practical and scientific purposes without the need of diacritics. It is based on the International Phonetic Alphabet with a few differences, such as j and y, which instead have the same (consonant) sound values as in English. |
1896 | https://en.wikipedia.org/wiki/Acquire | Acquire | Acquire is a multi-player mergers and acquisitions themed board game. It is played with tiles representing hotels that are arranged on the board, play money and stock certificates. The object of the game is to earn the most money by developing and merging hotel chains. When a chain in which a player owns stock is acquired by a larger chain, players earn money based on the size of the acquired chain. At the end of the game, all players liquidate their stock in order to determine which player has the most money. It was one of the most popular games in the 1960s 3M bookshelf game series, and the only one still published in the United States. |
1897 | https://en.wikipedia.org/wiki/Australian%20English | Australian English | Australian English (AusE, AusEng, AuE, AuEng, en-AU) is the set of varieties of the English language native to Australia. It is the country's common language and de facto national language; while Australia has no official language, English is the first language of the majority of the population, being the only language spoken in the home for about 72.7% of Australians. It is also the main language used in compulsory education, as well as federal, state and territorial legislatures and courts. |
1902 | https://en.wikipedia.org/wiki/American%20Airlines%20Flight%2077 | American Airlines Flight 77 | American Airlines Flight 77 was a scheduled American Airlines domestic transcontinental passenger flight from Washington Dulles International Airport in Dulles, Virginia, to Los Angeles International Airport in Los Angeles, California. The Boeing 757-223 aircraft serving the flight was hijacked by five Saudi men affiliated with al-Qaeda on the morning of September 11, 2001, as part of the September 11 attacks. They deliberately crashed the plane into the Pentagon in Arlington County, Virginia, near Washington, D.C., killing all 64 aboard (including six crew and themselves) and another 125 in the building. |
1905 | https://en.wikipedia.org/wiki/Ambush | Ambush | An ambush is a long-established military tactic in which combatants take advantage of concealment or the element of surprise to attack unsuspecting enemy combatants from concealed positions, such as among dense underbrush or behind hilltops. Ambushes have been used consistently throughout history, from ancient to modern warfare. In the 20th century, an ambush might involve thousands of soldiers on a large scale, such as over a choke point such as a mountain pass, or a small irregular band or insurgent group attacking a regular armed force patrol. Theoretically, a single well-armed and concealed soldier could ambush other troops in a surprise attack. Sometimes an ambush can involve the exclusive or combined use of improvised explosive devices, that allow the attackers to hit enemy convoys or patrols while minimizing the risk of being exposed to return fire. |
1908 | https://en.wikipedia.org/wiki/Abzyme | Abzyme | An abzyme (from antibody and enzyme), also called catmab (from catalytic monoclonal antibody), and most often called catalytic antibody, is a monoclonal antibody with catalytic activity. Abzymes are usually raised in lab animals immunized against synthetic haptens, but some natural abzymes can be found in normal humans (anti-vasoactive intestinal peptide autoantibodies) and in patients with autoimmune diseases such as systemic lupus erythematosus, where they can bind to and hydrolyze DNA. To date abzymes display only weak, modest catalytic activity and have not proved to be of any practical use. They are, however, subjects of considerable academic interest. Studying them has yielded important insights into reaction mechanisms, enzyme structure and function, catalysis, and the immune system itself. |
1909 | https://en.wikipedia.org/wiki/Adaptive%20radiation | Adaptive radiation | In evolutionary biology, adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms, particularly when a change in the environment makes new resources available, alters biotic interactions or opens new environmental niches. Starting with a single ancestor, this process results in the speciation and phenotypic adaptation of an array of species exhibiting different morphological and physiological traits. The prototypical example of adaptive radiation is finch speciation on the Galapagos ("Darwin's finches"), but examples are known from around the world. |
1910 | https://en.wikipedia.org/wiki/Agarose%20gel%20electrophoresis | Agarose gel electrophoresis | Agarose gel electrophoresis is a method of gel electrophoresis used in biochemistry, molecular biology, genetics, and clinical chemistry to separate a mixed population of macromolecules such as DNA or proteins in a matrix of agarose, one of the two main components of agar. The proteins may be separated by charge and/or size (isoelectric focusing agarose electrophoresis is essentially size independent), and the DNA and RNA fragments by length. Biomolecules are separated by applying an electric field to move the charged molecules through an agarose matrix, and the biomolecules are separated by size in the agarose gel matrix. |
1911 | https://en.wikipedia.org/wiki/Allele | Allele | The term allele (, ; ; modern formation from Greek ἄλλος állos, "other") |
1912 | https://en.wikipedia.org/wiki/Ampicillin | Ampicillin | Ampicillin is an antibiotic used to prevent and treat a number of bacterial infections, such as respiratory tract infections, urinary tract infections, meningitis, salmonellosis, and endocarditis. It may also be used to prevent group B streptococcal infection in newborns. It is used by mouth, by injection into a muscle, or intravenously. |
1913 | https://en.wikipedia.org/wiki/Annealing | Annealing | Annealing may refer to: |
1914 | https://en.wikipedia.org/wiki/Antimicrobial%20resistance | Antimicrobial resistance | Antimicrobial resistance (AMR) occurs when microbes evolve mechanisms that protect them from the effects of antimicrobials. Antibiotic resistance is a subset of AMR, that applies specifically to bacteria that become resistant to antibiotics. |
1915 | https://en.wikipedia.org/wiki/Antigen | Antigen | In immunology, an antigen (Ag) is a molecule or molecular structure or any foreign particulate matter or a pollen grain that can bind to a specific antibody or T-cell receptor. The presence of antigens in the body may trigger an immune response. The term antigen originally referred to a substance that is an antibody generator. Antigens can be proteins, peptides (amino acid chains), polysaccharides (chains of monosaccharides/simple sugars), lipids, or nucleic acids. |
1916 | https://en.wikipedia.org/wiki/Autosome | Autosome | An autosome is any chromosome that is not a sex chromosome. The members of an autosome pair in a diploid cell have the same morphology, unlike those in allosome pairs which may have different structures. The DNA in autosomes is collectively known as atDNA or auDNA. |
1919 | https://en.wikipedia.org/wiki/Antwerp%20%28disambiguation%29 | Antwerp (disambiguation) | Antwerp is a city in Belgium and capital of the Antwerp province. |

1921 | https://en.wikipedia.org/wiki/Al-Qaeda | Al-Qaeda | Al-Qaeda (; , , translation: "the Base", "the Foundation", alternatively spelled al-Qaida and al-Qa'ida), officially known as Qaedat al-Jihad, is a multinational militant Sunni Islamic extremist network composed of Salafist jihadists. It was founded in 1988 by Osama bin Laden, Abdullah Azzam, and several other Arab volunteers during the Soviet–Afghan War. |
1923 | https://en.wikipedia.org/wiki/Alessandro%20Volta | Alessandro Volta | Alessandro Giuseppe Antonio Anastasio Volta (, ; 18 February 1745 – 5 March 1827) was an Italian physicist, chemist and lay Catholic who was a pioneer of electricity and power who is credited as the inventor of the electric battery and the discoverer of methane. He invented the voltaic pile in 1799, and reported the results of his experiments in 1800 in a two-part letter to the President of the Royal Society. With this invention Volta proved that electricity could be generated chemically and debunked the prevalent theory that electricity was generated solely by living beings. Volta's invention sparked a great amount of scientific excitement and led others to conduct similar experiments, which eventually led to the development of the field of electrochemistry. |
1924 | https://en.wikipedia.org/wiki/Argo%20Navis | Argo Navis | Argo Navis (the Ship Argo), or simply Argo, was a large constellation in the southern sky. The genitive was "Argus Navis", abbreviated "Arg". Flamsteed and other early modern astronomers called it Navis (the Ship), genitive "Navis", abbreviated "Nav". |
1925 | https://en.wikipedia.org/wiki/Andromeda%20%28mythology%29 | Andromeda (mythology) | In Greek mythology, Andromeda (; Greek: Ἀνδρομέδα, Androméda or Ἀνδρομέδη, Andromédē) is the daughter of the king of Aethiopia, Cepheus, and his wife, Cassiopeia. When Cassiopeia boasts that she is more beautiful than the Nereids, Poseidon sends the sea monster Cetus to ravage the coast of Aethiopia as divine punishment. Andromeda is chained to a rock as a sacrifice to sate the monster, but is saved from death by Perseus, who marries her and takes her to Greece to reign as his queen. |
1926 | https://en.wikipedia.org/wiki/Antlia | Antlia | Antlia (; from Ancient Greek ἀντλία) is a constellation in the Southern Celestial Hemisphere. Its name means "pump" in Latin and Greek; it represents an air pump. Originally Antlia Pneumatica, the constellation was established by Nicolas-Louis de Lacaille in the 18th century. Its non-specific (single-word) name, already in limited use, was preferred by John Herschel then welcomed by the astronomic community which officially accepted this. North of stars forming some of the sails of the ship Argo Navis (the constellation Vela), Antlia is completely visible from latitudes south of 49 degrees north. |
1927 | https://en.wikipedia.org/wiki/Ara%20%28constellation%29 | Ara (constellation) | Ara (Latin for "the Altar") is a southern constellation between Scorpius, Telescopium, Triangulum Australe, and Norma. It was (as ) one of the Greek bulk (namely 48) described by the 2nd-century astronomer Ptolemy, and it remains one of the 88 modern constellations designated by the International Astronomical Union. |
1928 | https://en.wikipedia.org/wiki/Auriga | Auriga | Auriga or AURIGA can refer to: |
1930 | https://en.wikipedia.org/wiki/Arkansas | Arkansas | Arkansas () is a landlocked state in the South Central region of the United States, home to more than three million people as of 2018. Its name is from the Osage language, a Dhegiha Siouan language, and referred to their relatives, the Quapaw people. The state's diverse geography ranges from the mountainous regions of the Ozark and Ouachita Mountains, which make up the U.S. Interior Highlands, to the densely forested land in the south known as the Arkansas Timberlands, to the eastern lowlands along the Mississippi River and the Arkansas Delta. |
1931 | https://en.wikipedia.org/wiki/Atmosphere%20%28disambiguation%29 | Atmosphere (disambiguation) | An atmosphere is a gas layer around a celestial body. |
1933 | https://en.wikipedia.org/wiki/Apus | Apus | Apus is a small constellation in the southern sky. It represents a bird-of-paradise, and its name means "without feet" in Greek because the bird-of-paradise was once wrongly believed to lack feet. First depicted on a celestial globe by Petrus Plancius in 1598, it was charted on a star atlas by Johann Bayer in his 1603 Uranometria. The French explorer and astronomer Nicolas Louis de Lacaille charted and gave the brighter stars their Bayer designations in 1756. |
1934 | https://en.wikipedia.org/wiki/Abadan%2C%20Iran | Abadan, Iran | Abadan ( Ābādān, ) is a city and capital of Abadan County, Khuzestan Province, which is located in the southwest of Iran. It lies on Abadan Island ( long, 3–19 km or 2–12 miles wide). The island is bounded in the west by the Arvand waterway and to the east by the Bahmanshir outlet of the Karun River (the Arvand Rood), from the Persian Gulf, near the Iran–Iraq border.

1937 | https://en.wikipedia.org/wiki/Alexander%20Fleming | Alexander Fleming | Sir Alexander Fleming (6 August 1881 – 11 March 1955) was a Scottish physician and microbiologist, best known for discovering the world's first broadly effective antibiotic substance, which he named penicillin. His discovery in 1928 of what was later named benzylpenicillin (or penicillin G) from the mould Penicillium rubens is described as the "single greatest victory ever achieved over disease." For this discovery, he shared the Nobel Prize in Physiology or Medicine in 1945 with Howard Florey and Ernst Boris Chain. |
1938 | https://en.wikipedia.org/wiki/Andrew%20Carnegie | Andrew Carnegie | Andrew Carnegie (, English approximation: ; November 25, 1835August 11, 1919) was a Scottish-American industrialist and philanthropist. Carnegie led the expansion of the American steel industry in the late 19th century and became one of the richest Americans in history. He became a leading philanthropist in the United States and in the British Empire. During the last 18 years of his life, he gave away around $350 million (roughly $ billion in ), almost 90 percent of his fortune, to charities, foundations and universities. His 1889 article proclaiming "The Gospel of Wealth" called on the rich to use their wealth to improve society, expressed support for progressive taxation and an estate tax, and stimulated a wave of philanthropy. |
1939 | https://en.wikipedia.org/wiki/Approximant | Approximant | Approximants are speech sounds that involve the articulators approaching each other but not narrowly enough nor with enough articulatory precision to create turbulent airflow. Therefore, approximants fall between fricatives, which do produce a turbulent airstream, and vowels, which produce no turbulence. This class is composed of sounds like (as in rest) and semivowels like and (as in yes and west, respectively), as well as lateral approximants like (as in less). |
1940 | https://en.wikipedia.org/wiki/Astronomer%20Royal | Astronomer Royal | Astronomer Royal is a senior post in the Royal Households of the United Kingdom. There are two officers, the senior being the Astronomer Royal dating from 22 June 1675; the second is the Astronomer Royal for Scotland dating from 1834. |
1941 | https://en.wikipedia.org/wiki/Aeon | Aeon | The word aeon , also spelled eon (in American and Australian English), originally meant "life", "vital force" or "being", "generation" or "a period of time", though it tended to be translated as "age" in the sense of "ages", "forever", "timeless" or "for eternity". It is a Latin transliteration from the koine Greek word (ho aion), from the archaic (aiwon). In Homer it typically refers to life or lifespan. Its latest meaning is more or less similar to the Sanskrit word kalpa and Hebrew word olam. A cognate Latin word aevum or aeuum (cf. ) for "age" is present in words such as longevity and mediaeval. |
1942 | https://en.wikipedia.org/wiki/Airline | Airline | An airline is a company that provides air transport services for traveling passengers and freight. Airlines use aircraft to supply these services and may form partnerships or alliances with other airlines for codeshare agreements, in which they both offer and operate the same flight. Generally, airline companies are recognized with an air operating certificate or license issued by a governmental aviation body. Airlines may be scheduled or charter operators. |
1943 | https://en.wikipedia.org/wiki/Australian%20Democrats | Australian Democrats | The Australian Democrats is a centrist political party in Australia. Founded in 1977 from a merger of the Australia Party and the New Liberal Movement, both of which were descended from Liberal Party dissenting splinter groups, it was Australia's largest minor party from its formation in 1977 through to 2004 and frequently held the balance of power in the Senate during that time. |
1944 | https://en.wikipedia.org/wiki/Australian%20Capital%20Territory | Australian Capital Territory | The Australian Capital Territory (commonly abbreviated as ACT), known as the Federal Capital Territory (FCT) until 1938, is a landlocked federal territory of Australia containing the national capital Canberra and some surrounding townships.

Aotus (plant), one of the plant genera commonly known as golden peas in the family Fabaceae (bean family)
Aotus (monkey), the genus of night monkeys in the family Aotidae
AOTUS, the acronym for the Archivist of the United States |
1948 | https://en.wikipedia.org/wiki/Ally%20McBeal | Ally McBeal | Ally McBeal is an American legal comedy-drama television series, originally aired on Fox from September 8, 1997, to May 20, 2002. Created by David E. Kelley, the series stars Calista Flockhart in the title role as a lawyer working in the Boston law firm Cage and Fish, with other lawyers whose lives and loves are eccentric, humorous, and dramatic. The series received critical acclaim in its early seasons, winning the Golden Globe Award for Best Television Series – Musical or Comedy in 1997 and 1998, and also winning the Emmy Award for Outstanding Comedy Series in 1999. As of 2021, a revival is possibly in development. |
1949 | https://en.wikipedia.org/wiki/Andreas%20Capellanus | Andreas Capellanus | Andreas Capellanus (Capellanus meaning "chaplain"), also known as Andrew the Chaplain, and occasionally by a French translation of his name, André le Chapelain, was the 12th-century author of a treatise commonly known as De amore ("About Love"), and often known in English, somewhat misleadingly, as The Art of Courtly Love, though its realistic, somewhat cynical tone suggests that it is in some measure an antidote to courtly love. Little is known of Andreas Capellanus's life, but he is presumed to have been a courtier of Marie de Champagne, and probably of French origin. |
1950 | https://en.wikipedia.org/wiki/American%20Civil%20Liberties%20Union | American Civil Liberties Union | The American Civil Liberties Union (ACLU) is a nonprofit organization founded in 1920 "to defend and preserve the individual rights and liberties guaranteed to every person in this country by the Constitution and laws of the United States". The ACLU works through litigation and lobbying, and has over 1,200,000 members, with an annual budget of over $300 million. Affiliates of the ACLU are active in all 50 states, the District of Columbia, and Puerto Rico. The ACLU provides legal assistance in cases where it considers civil liberties to be at risk. Legal support from the ACLU can take the form of direct legal representation or preparation of amicus curiae briefs expressing legal arguments when another law firm is already providing representation. |
1955 | https://en.wikipedia.org/wiki/Adobe%20Inc. | Adobe Inc. | Adobe Inc. ( ), originally called Adobe Systems Incorporated, is an American multinational computer software company incorporated in Delaware

1957 | https://en.wikipedia.org/wiki/Alexander%20Technique | Alexander Technique | The Alexander Technique, named after its developer Frederick Matthias Alexander (1869–1955), is a popular type of alternative therapy based on the idea that poor posture gives rise to a range of health problems. |
1960 | https://en.wikipedia.org/wiki/Andrea%20Alciato | Andrea Alciato | Andrea Alciato (8 May 149212 January 1550), commonly known as Alciati (Andreas Alciatus), was an Italian jurist and writer. He is regarded as the founder of the French school of legal humanists. |
1962 | https://en.wikipedia.org/wiki/Apparent%20magnitude | Apparent magnitude | Apparent magnitude () is a measure of the brightness of a star or other astronomical object observed from Earth. An object's apparent magnitude depends on its intrinsic luminosity, its distance from Earth, and any extinction of the object's light caused by interstellar dust along the line of sight to the observer. |
1963 | https://en.wikipedia.org/wiki/Absolute%20magnitude | Absolute magnitude | Absolute magnitude () is a measure of the luminosity of a celestial object, on an inverse logarithmic astronomical magnitude scale. An object's absolute magnitude is defined to be equal to the apparent magnitude that the object would have if it were viewed from a distance of exactly , without extinction (or dimming) of its light due to absorption by interstellar matter and cosmic dust. By hypothetically placing all objects at a standard reference distance from the observer, their luminosities can be directly compared among each other on a magnitude scale. |
1965 | https://en.wikipedia.org/wiki/Apollo%201 | Apollo 1 | Apollo 1, initially designated AS-204, was the first crewed mission of the United States Apollo program, the undertaking to land the first man on the Moon. It was planned to launch on February 21, 1967, as the first low Earth orbital test of the Apollo command and service module. The mission never flew; a cabin fire during a launch rehearsal test at Cape Kennedy Air Force Station Launch Complex 34 on January 27 killed all three crew members—Command Pilot Gus Grissom, Senior Pilot Ed White, and Pilot Roger B. Chaffee—and destroyed the command module (CM). The name Apollo1, chosen by the crew, was made official by NASA in their honor after the fire. |
1966 | https://en.wikipedia.org/wiki/Apollo%2010 | Apollo 10 | Apollo 10 (May 1826, 1969) was a human spaceflight, the fourth crewed mission in the United States Apollo program, and the second (after Apollo8) to orbit the Moon. It was the Fmission: a "dress rehearsal" for the first Moon landing, testing all the components and procedures just short of actually landing. While astronaut John Young remained in the Command Module orbiting the Moon, astronauts Thomas Stafford and Gene Cernan flew the Apollo Lunar Module (LM) to a descent orbit within of the lunar surface, the point where powered descent for landing would begin. After orbiting the Moon 31 times, Apollo 10 returned safely to Earth, and its success enabled the first actual landing (Apollo 11) two months later. |
1967 | https://en.wikipedia.org/wiki/Apollo%2012 | Apollo 12 | Apollo 12 (November 1424, 1969) was the sixth crewed flight in the United States Apollo program and the second to land on the Moon. It was launched on November 14, 1969, from the Kennedy Space Center, Florida. Commander Charles "Pete" Conrad and Lunar Module Pilot Alan L. Bean performed just over one day and seven hours of lunar surface activity while Command Module Pilot Richard F. Gordon remained in lunar orbit. |
1968 | https://en.wikipedia.org/wiki/Apollo%2014 | Apollo 14 | Apollo 14 (January 31, 1971February 9, 1971) was the eighth crewed mission in the United States Apollo program, the third to land on the Moon, and the first to land in the lunar highlands. It was the last of the "H missions", landings at specific sites of scientific interest on the Moon for two-day stays with two lunar extravehicular activities (EVAs or moonwalks). |
1969 | https://en.wikipedia.org/wiki/Apollo%2015 | Apollo 15 | Apollo 15 (July 26August 7, 1971) was the ninth crewed mission in the United States' Apollo program and the fourth to land on the Moon. It was the first J mission, with a longer stay on the Moon and a greater focus on science than earlier landings. Apollo 15 saw the first use of the Lunar Roving Vehicle. |
1970 | https://en.wikipedia.org/wiki/Apollo%2016 | Apollo 16 | Apollo 16 (April 1627, 1972) was the tenth crewed mission in the United States Apollo space program, administered by NASA, and the fifth and next-to-last to land on the Moon. It was the second of Apollo's "J missions", with an extended stay on the lunar surface, a focus on science, and the use of the Lunar Roving Vehicle (LRV). The landing and exploration were in the Descartes Highlands, a site chosen because some scientists expected it to be an area formed by volcanic action, though this proved to not be the case. |
1971 | https://en.wikipedia.org/wiki/Apollo%2017 | Apollo 17 | Apollo 17 (December 719, 1972) was the final mission of NASA's Apollo program, the most recent time humans have set foot on the Moon or traveled beyond low Earth orbit. Commander Eugene Cernan and Lunar Module Pilot Harrison Schmitt walked on the Moon, while Command Module Pilot Ronald Evans orbited above. Schmitt was the only professional geologist to land on the Moon, selected in place of Joe Engle with NASA under pressure to send a scientist to the Moon. The mission's heavy emphasis on science meant the inclusion of a number of new experiments, including a biological experiment containing five mice carried in the command module. |
1973 | https://en.wikipedia.org/wiki/American%20Revolution | American Revolution | The American Revolution was an ideological and political revolution that occurred in British America between 1765 and 1791. The Americans in the Thirteen Colonies formed independent states that defeated the British in the American Revolutionary War (1775–1783), gaining independence from the British Crown, establishing the constitution that created the United States of America, the first modern constitutional liberal democracy. |

1975 | https://en.wikipedia.org/wiki/Alan%20Ayckbourn | Alan Ayckbourn | Sir Alan Ayckbourn (born 12 April 1939) is a prolific British playwright and director. He has written and produced as of 2021, more than eighty full-length plays in Scarborough and London and was, between 1972 and 2009, the artistic director of the Stephen Joseph Theatre in Scarborough, where all but four of his plays have received their first performance. More than 40 have subsequently been produced in the West End, at the Royal National Theatre or by the Royal Shakespeare Company since his first hit Relatively Speaking opened at the Duke of York's Theatre in 1969. |
1979 | https://en.wikipedia.org/wiki/Alpha%20Centauri | Alpha Centauri | Alpha Centauri is a gravitationally bound system of the closest stars and exoplanets to our Solar System at 4.37 light-years (1.34 parsecs) from the Sun. The name is Latinized from α Centauri, and abbreviated Alpha Cen or α Cen. It is a triple star system consisting of α Centauri A (officially Rigil Kentaurus), α Centauri B (officially Toliman), and the closest star α Centauri C (officially Proxima Centauri). |
1980 | https://en.wikipedia.org/wiki/Amiga | Amiga | The Amiga is a family of personal computers introduced by Commodore in 1985. The original model is one of a number of computers with 16- or 32-bit processors, 256 KB or more of RAM, mouse-based GUIs, and significantly improved graphics and audio compared to previous 8-bit systems. This includes the Atari ST – released earlier the same year – as well as the Macintosh and Acorn Archimedes. Based on the Motorola 68000 microprocessor, the Amiga differs from its contemporaries through the inclusion of custom hardware to accelerate graphics and sound, including sprites and a blitter, and a pre-emptive multitasking operating system called AmigaOS. |

1986 | https://en.wikipedia.org/wiki/Actinophryid | Actinophryid | The actinophryids are an order of heliozoa, a polyphyletic array of protists. The actinophryids are stramenopiles, having a close relationship with pedinellids and Ciliophrys. They are common in fresh water and occasionally found in marine and soil habitats. Actinophryids are unicellular and roughly spherical in shape, with many axopodia that radiate outward from the cell body. Axopodia are a type of pseudopodia that are supported by hundreds of microtubules arranged in interlocking spirals and forming a needle-like internal structure or axoneme. Small granules, extrusomes, that lie under the membrane of the body and axopodia capture flagellates, ciliates and small metazoa that make contact with the arms. |
1988 | https://en.wikipedia.org/wiki/Abel%20Tasman | Abel Tasman | Abel Janszoon Tasman (; 160310 October 1659) was a Dutch seafarer, explorer, and merchant, best known for his voyages of 1642 and 1644 in the service of the Dutch East India Company (VOC). He was the first known European explorer to reach New Zealand and the islands of Fiji and Van Diemen's Land (now Tasmania). |

1997 | https://en.wikipedia.org/wiki/Algebraic%20geometry | Algebraic geometry | Algebraic geometry is a branch of mathematics, classically studying zeros of multivariate polynomials. Modern algebraic geometry is based on the use of abstract algebraic techniques, mainly from commutative algebra, for solving geometrical problems about these sets of zeros. |
1998 | https://en.wikipedia.org/wiki/Austin%2C%20Texas | Austin, Texas | Austin is the capital city of the U.S. state of Texas, as well as the seat and largest city of Travis County, with portions extending into Hays and Williamson counties. Incorporated on December 27, 1839, it is the 11th-most populous city in the United States, the fourth-most-populous city in Texas, the second-most-populous state capital city after Phoenix, Arizona, and the most populous state capital that is not also the most populous city in its state. It has been one of the fastest growing large cities in the United States since 2010. The Greater Austin and Greater San Antonio areas are separated from each other by approximately along Interstate 35. It is anticipated that both regions may form a new metroplex similar to Dallas and Fort Worth. Austin is the southernmost state capital in the contiguous United States and is considered a "Beta −" global city as categorized by the Globalization and World Cities Research Network. |
2003 | https://en.wikipedia.org/wiki/Argument%20from%20morality | Argument from morality | The argument from morality is an argument for the existence of God. Arguments from morality tend to be based on moral normativity or moral order. Arguments from moral normativity observe some aspect of morality and argue that God is the best or only explanation for this, concluding that God must exist. Arguments from moral order are based on the asserted need for moral order to exist in the universe. They claim that, for this moral order to exist, God must exist to support it. The argument from morality is noteworthy in that one cannot evaluate the soundness of the argument without attending to almost every important philosophical issue in meta-ethics. |

2006 | https://en.wikipedia.org/wiki/Auschwitz%20concentration%20camp | Auschwitz concentration camp | Auschwitz concentration camp ( (); also or ) was a complex of over 40 concentration and extermination camps operated by Nazi Germany in occupied Poland (in a portion annexed into Germany in 1939) during World War II and the Holocaust. It consisted of Auschwitz I, the main camp (Stammlager) in Oświęcim; Auschwitz II-Birkenau, a concentration and extermination camp with gas chambers; Auschwitz III-Monowitz, a labor camp for the chemical conglomerate IG Farben; and dozens of subcamps. The camps became a major site of the Nazis' final solution to the Jewish question. |
2007 | https://en.wikipedia.org/wiki/Archery | Archery | Archery is the sport, practice, or skill of using a bow to shoot arrows. The word comes from the Latin arcus, meaning bow. Historically, archery has been used for hunting and combat. In modern times, it is mainly a competitive sport and recreational activity. A person who practices archery is typically called an archer or a bowman, and a person who is fond of or an expert at archery is sometimes called a toxophilite or a marksman. |
2009 | https://en.wikipedia.org/wiki/Alvar%20Aalto | Alvar Aalto | Hugo Alvar Henrik Aalto (; 3 February 1898 – 11 May 1976) was a Finnish architect and designer. His work includes architecture, furniture, textiles and glassware, as well as sculptures and paintings. He never regarded himself as an artist, seeing painting and sculpture as "branches of the tree whose trunk is architecture." Aalto's early career ran in parallel with the rapid economic growth and industrialization of Finland during the first half of the 20th century. Many of his clients were industrialists, among them the Ahlström-Gullichsen family. The span of his career, from the 1920s to the 1970s, is reflected in the styles of his work, ranging from Nordic Classicism of the early work, to a rational International Style Modernism during the 1930s to a more organic modernist style from the 1940s onwards. |
2011 | https://en.wikipedia.org/wiki/Comparison%20of%20American%20and%20British%20English | Comparison of American and British English | The English language was introduced to the Americas by British colonisation, beginning in the late 16th and early 17th centuries. The language also spread to numerous other parts of the world as a result of British trade and colonisation and the spread of the former British Empire, which, by 1921, included 470–570 million people, about a quarter of the world's population. Written forms of British and American English as found in newspapers and textbooks vary little in their essential features, with only occasional noticeable differences. |
2014 | https://en.wikipedia.org/wiki/Atomic%20semantics | Atomic semantics | Atomic semantics is a type of guarantee provided by a data register shared by several processors in a parallel machine or in a network of computers working together.
Atomic semantics are very strong. An atomic register provides strong guarantees even when there is concurrency and failures. |
2015 | https://en.wikipedia.org/wiki/Antarctic%20Circumpolar%20Current | Antarctic Circumpolar Current | The Antarctic Circumpolar Current (ACC) is an ocean current that flows clockwise (as seen from the South Pole) from west to east around Antarctica. An alternative name for the ACC is the West Wind Drift. The ACC is the dominant circulation feature of the Southern Ocean and has a mean transport estimated at 100–150 Sverdrups (Sv, million m3/s), or possibly even higher, making it the largest ocean current. The current is circumpolar due to the lack of any landmass connecting with Antarctica and this keeps warm ocean waters away from Antarctica, enabling that continent to maintain its huge ice sheet. |
2017 | https://en.wikipedia.org/wiki/Arbor%20Day | Arbor Day | Arbor Day (or Arbour in some countries) is a secular day of observance in which individuals and groups are encouraged to plant trees. Today, many countries observe such a holiday. Though usually observed in the spring, the date varies, depending on climate and suitable planting season. |
2018 | https://en.wikipedia.org/wiki/A.%20J.%20Ayer | A. J. Ayer | Sir Alfred Jules "Freddie" Ayer (; 29 October 1910 – 27 June 1989), usually cited as A. J. Ayer, was an English philosopher known for his promotion of logical positivism, particularly in his books Language, Truth, and Logic (1936) and The Problem of Knowledge (1956). |

He was a founding member and the de facto early leader of the mathematical Bourbaki group. The philosopher Simone Weil was his sister. The writer Sylvie Weil is his daughter. |
2020 | https://en.wikipedia.org/wiki/Achaeans%20%28Homer%29 | Achaeans (Homer) | The Achaeans (; Akhaioí, "the Achaeans" or "of Achaea") constitute one of the collective names for the Greeks in Homer's Iliad (used 598 times) and Odyssey. The other common names are Danaans (; Danaoi; used 138 times in the Iliad) and Argives (; ; used 182 times in the Iliad) while Panhellenes ( Panhellenes, "All of the Greeks") and Hellenes (; Hellenes) both appear only once; all of the aforementioned terms were used synonymously to denote a common Greek civilizational identity. In the historical period, the Achaeans were the inhabitants of the region of Achaea, a region in the north-central part of the Peloponnese. The city-states of this region later formed a confederation known as the Achaean League, which was influential during the 3rd and 2nd centuries BC. |
2021 | https://en.wikipedia.org/wiki/Atle%20Selberg | Atle Selberg | Atle Selberg (14 June 1917 – 6 August 2007) was a Norwegian mathematician known for his work in analytic number theory and the theory of automorphic forms, and in particular for bringing them into relation with spectral theory. He was awarded the Fields Medal in 1950 and an honorary Abel Prize in 2002. |
2023 | https://en.wikipedia.org/wiki/Aeschylus | Aeschylus | Aeschylus (, ; ; c. 525/524 – c. 456/455 BC) was an ancient Greek tragedian, and is often described as the father of tragedy. Academic knowledge of the genre begins with his work, and understanding of earlier Greek tragedy is largely based on inferences made from reading his surviving plays. According to Aristotle, he expanded the number of characters in the theatre and allowed conflict among them. Formerly, characters interacted only with the chorus. |
2024 | https://en.wikipedia.org/wiki/Amber%20Road | Amber Road | The Amber Road was an ancient trade route for the transfer of amber from the coastal areas of Sicily and later from the North Sea and the Baltic Sea to the Mediterranean Sea. Prehistoric trade routes between Northern and Southern Europe were defined by the amber trade. |

2039 | https://en.wikipedia.org/wiki/Avionics | Avionics | Avionics (a blend of aviation and electronics) are the electronic systems used on aircraft, artificial satellites, and spacecraft. Avionic systems include communications, navigation, the display and management of multiple systems, and the hundreds of systems that are fitted to aircraft to perform individual functions. These can be as simple as a searchlight for a police helicopter or as complicated as the tactical system for an airborne early warning platform. |
2041 | https://en.wikipedia.org/wiki/Ares | Ares | Ares (; , Árēs ) is the Greek god of courage and war. He is one of the Twelve Olympians, and the son of Zeus and Hera. The Greeks were ambivalent toward him. He embodies the physical valor necessary for success in war but can also personify sheer brutality and bloodlust, in contrast to his sister, the armored Athena, whose martial functions include military strategy and generalship. An association with Ares endows places, objects and other deities with a savage, dangerous, or militarized quality. |
2042 | https://en.wikipedia.org/wiki/Alexander%20Grothendieck | Alexander Grothendieck | Alexander Grothendieck (; ; ; 28 March 1928 – 13 November 2014) was a stateless and then French mathematician who became the leading figure in the creation of modern algebraic geometry. His research extended the scope of the field and added elements of commutative algebra, homological algebra, sheaf theory and category theory to its foundations, while his so-called "relative" perspective led to revolutionary advances in many areas of pure mathematics. He is considered by many to be the greatest mathematician of the 20th century. |
2047 | https://en.wikipedia.org/wiki/Alcoholics%20Anonymous | Alcoholics Anonymous | Alcoholics Anonymous (AA) is an abstinence based international fellowship of dedicated to sobriety and recovery from alcoholism through its spiritually inclined Twelve Step program. As prescribed by its Twelve Traditions, AA supports itself through the strictly voluntary donations from members only. The Traditions also establish that AA as non-professional, non-denominational, and apolitical, with an avowed desire to stop drinking as its sole requirement for membership. Though AA has not endorsed the disease model of alcoholism, to which its program is nonetheless sympathetic, its wider acceptance is partly due to many members independently promulgating it. A recent scientific review shows that by many measures AA does as well or better than other clinical interventions. In particular, AA has better abstinence rates with lower medical costs than no treatment or other clinical interventions. As of 2020, having spread to diverse cultures, including geopolitical areas normally resistant to grassroots movements, AA estimated its worldwide membership to be over two million with 75% of those in the U.S. and Canada. |
2049 | https://en.wikipedia.org/wiki/Alpha%20compositing | Alpha compositing | In computer graphics, alpha compositing or alpha blending is the process of combining one image with a background to create the appearance of partial or full transparency. It is often useful to render picture elements (pixels) in separate passes or layers and then combine the resulting 2D images into a single, final image called the composite. Compositing is used extensively in film when combining computer-rendered image elements with live footage. Alpha blending is also used in 2D computer graphics to put rasterized foreground elements over a background. |
2052 | https://en.wikipedia.org/wiki/Array%20data%20structure | Array data structure | In computer science, an array data structure, or simply an array, is a data structure consisting of a collection of elements (values or variables), each identified by at least one array index or key. An array is stored such that the position of each element can be computed from its index tuple by a mathematical formula. The simplest type of data structure is a linear array, also called one-dimensional array. |
2053 | https://en.wikipedia.org/wiki/Advance%20Australia%20Fair | Advance Australia Fair | "Advance Australia Fair" is the national anthem of Australia. Written by Scottish-born composer Peter Dodds McCormick, the song was first performed in 1878, sung in Australia as a patriotic song. It first replaced "God Save the Queen" as the official national anthem in 1974, following a nationwide opinion survey. "God Save the Queen" was reinstated in January 1976, but a plebiscite to choose the national song in 1977 preferred "Advance Australia Fair", which was restored in 1984. "God Save the Queen" became known as the royal anthem, which is used at public engagements attended by the Queen or members of the Royal Family. The 1984 version of "Advance Australia Fair" has lyrics modified from McCormick's original and verses trimmed down from four to two. In January 2021 the lyrics were changed again. |
