https://en.wikipedia.org/wiki/Angle
Angle
In Euclidean geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. Angles formed by two rays lie in the plane that contains the rays. Angles are also formed by the intersection of two planes. These are called dihedral angles. Two intersecting curves may also define an angle, which is the angle of the rays lying tangent to the respective curves at their point of intersection.

https://en.wikipedia.org/wiki/Acoustics
Acoustics
Acoustics is a branch of physics that deals with the study of mechanical waves in gases, liquids, and solids including topics such as vibration, sound, ultrasound and infrasound. A scientist who works in the field of acoustics is an acoustician while someone working in the field of acoustics technology may be called an acoustical engineer. The application of acoustics is present in almost all aspects of modern society with the most obvious being the audio and noise control industries.

https://en.wikipedia.org/wiki/Atomic%20physics
Atomic physics
Atomic physics is the field of physics that studies atoms as an isolated system of electrons and an atomic nucleus. Atomic physics typically refers to the study of atomic structure and the interaction between atoms. It is primarily concerned with the way in which electrons are arranged around the nucleus and the processes by which these arrangements change. This comprises ions, neutral atoms and, unless otherwise stated, it can be assumed that the term atom includes ions.

https://en.wikipedia.org/wiki/American%20Sign%20Language
American Sign Language
American Sign Language (ASL) is a natural language that serves as the predominant sign language of Deaf communities in the United States and most of Anglophone Canada. ASL is a complete and organized visual language that is expressed by facial expression as well as movements and motions with the hands. Besides North America, dialects of ASL and ASL-based creoles are used in many countries around the world, including much of West Africa and parts of Southeast Asia. ASL is also widely learned as a second language, serving as a lingua franca. ASL is most closely related to French Sign Language (LSF). It has been proposed that ASL is a creole language of LSF, although ASL shows features atypical of creole languages, such as agglutinative morphology.

Applet
In computing, an applet is any small application that performs one specific task that runs within the scope of a dedicated widget engine or a larger program, often as a plug-in. The term is frequently used to refer to a Java applet, a program written in the Java programming language that is designed to be placed on a web page. Applets are typical examples of transient and auxiliary applications that don't monopolize the user's attention. Applets are not full-featured application programs, and are intended to be easily accessible.

https://en.wikipedia.org/wiki/Alternate%20history
Alternate history
Alternate history (also alternative history, althist, AH) is a genre of speculative fiction of stories in which one or more historical events occur and are resolved differently than in real life. As conjecture based upon historical fact, alternative history stories propose What if? scenarios about crucial events in human history, and present outcomes very different from the historical record. Alternate history also is a subgenre of literary fiction, science fiction, and historical fiction; as literature, alternate history uses the tropes of the genre to answer the What if? speculations of the story.

https://en.wikipedia.org/wiki/Atomic%20orbital
Atomic orbital
In atomic theory and quantum mechanics, an atomic orbital is a mathematical function describing the location and wave-like behavior of an electron in an atom. This function can be used to calculate the probability of finding any electron of an atom in any specific region around the atom's nucleus. The term atomic orbital may also refer to the physical region or space where the electron can be calculated to be present, as predicted by the particular mathematical form of the orbital.

https://en.wikipedia.org/wiki/Amino%20acid
Amino acid
Amino acids are organic compounds that contain amino () and carboxylate functional groups, along with a side chain (R group) specific to each amino acid. The elements present in every amino acid are carbon (C), hydrogen (H), oxygen (O), and nitrogen (N); in addition sulfur (S) is present in the side chains of cysteine and methionine, and selenium (Se) in the less common amino acid selenocysteine. More than 500 naturally occurring amino acids are known to constitute monomer units of peptides, including proteins, (though only 20 appear in the genetic code, plus selenocysteine, which is encoded in a special way).

https://en.wikipedia.org/wiki/Area
Area
Area is the quantity that expresses the extent of a two-dimensional region, shape, or planar lamina, in the plane. Surface area is its analog on the two-dimensional surface of a three-dimensional object. Area can be understood as the amount of material with a given thickness that would be necessary to fashion a model of the shape, or the amount of paint necessary to cover the surface with a single coat. It is the two-dimensional analog of the length of a curve (a one-dimensional concept) or the volume of a solid (a three-dimensional concept).

https://en.wikipedia.org/wiki/Astronomical%20unit
Astronomical unit
The astronomical unit (symbol: au, or or AU) is a unit of length, roughly the distance from Earth to the Sun and equal to about or ~8 light minutes. The actual distance from Earth to the Sun varies by about 3% as Earth orbits the Sun, from a maximum (aphelion) to a minimum (perihelion) and back again once each year. The astronomical unit was originally conceived as the average of Earth's aphelion and perihelion; however, since 2012 it has been defined as exactly (see below for several conversions).

https://en.wikipedia.org/wiki/Artist
Artist
An artist is a person engaged in an activity related to creating art, practicing the arts, or demonstrating an art. The common usage in both everyday speech and academic discourse refers to a practitioner in the visual arts only. However, the term is also often used in the entertainment business, especially in a business context, for musicians and other performers (although less often for actors). "Artiste" (French for artist) is a variant used in English in this context, but this use has become rare. Use of the term "artist" to describe writers is valid, but less common, and mostly restricted to contexts like used in criticism.

Ashoka
Ashoka (; Brāhmi: 𑀅𑀲𑁄𑀓, Asoka, IAST: Aśoka), also known as Ashoka the Great, was an Indian emperor of the Maurya Dynasty, son of Bindusara, who ruled almost all of the Indian subcontinent from to 232 BCE. Ashoka promoted the spread of Buddhism across ancient Asia. Considered by many to be one of India's greatest emperors, Ashoka expanded Chandragupta's empire to reign over territory stretching from present-day Afghanistan in the west to present-day Bangladesh in the east. It covered the entire Indian subcontinent except for parts of present-day Tamil Nadu. The empire's capital was Pataliputra (in Magadha, present-day Patna), with provincial capitals at Takshashila (later Taxila) and Ujjain. Ashoka, after the war of Kalinga, got upset with the bloodshed and vowed to never fight again. He patronized Buddhism during his reign.

https://en.wikipedia.org/wiki/Arianism
Arianism
Arianism (, ) is a Christological doctrine first attributed to Arius (), a Christian presbyter from Ptolemais, Libya Arian theology holds that Jesus Christ is the Son of God, who was begotten by God the Father with the difference that the Son of God did not always exist but was begotten within time by God the Father, therefore Jesus was not co-eternal with God the Father. With regard to the Trinity, there are, theoretically speaking, two possibilities: Either to affirm unity and deny plurality in God, and vice versa. All trinitarian heresies are but variations on these two "choices" ('choices' being the meaning of the Greek ).

https://en.wikipedia.org/wiki/Alpha%20decay
Alpha decay
Alpha decay or α-decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle (helium nucleus) and thereby transforms or 'decays' into a different atomic nucleus, with a mass number that is reduced by four and an atomic number that is reduced by two. An alpha particle is identical to the nucleus of a helium-4 atom, which consists of two protons and two neutrons. It has a charge of and a mass of . For example, uranium-238 decays to form thorium-234.

Augustus
Caesar Augustus (23 September 63 BC – 19 August AD 14), also known as Octavian, was the first Roman emperor, reigning from 27 BC until his death in AD 14. His status as the founder of the Roman Principate (the first phase of the Roman Empire) has consolidated a legacy as one of the most effective leaders in human history. The reign of Augustus initiated an era of relative peace known as the Pax Romana. The Roman world was largely free from large-scale conflict for more than two centuries, despite continuous wars of imperial expansion on the Empire's frontiers and the year-long civil war known as the "Year of the Four Emperors" over the imperial succession.

https://en.wikipedia.org/wiki/Transport%20in%20Antarctica
Transport in Antarctica
Transport in Antarctica has transformed from explorers crossing the isolated remote area of Antarctica by foot to a more open era due to human technologies enabling more convenient and faster transport, predominantly by air and water, but also by land as well. Transportation technologies on a remote area like Antarctica need to be able to deal with extremely low temperatures and continuous winds to ensure the travelers' safety. Due to the fragility of the Antarctic environment, only a limited amount of transport movements can take place and sustainable transportation technologies have to be used to reduce the ecological footprint. The infrastructure of land, water and air transport needs to be safe and sustainable. Currently thousands of tourists and hundreds of scientists a year depend on the Antarctic transportation system.

Arminianism
Arminianism is a branch of Protestantism based on the theological ideas of the Dutch Reformed theologian Jacobus Arminius (1560–1609) and his historic supporters known as Remonstrants. Dutch Arminianism was originally articulated in the Remonstrance (1610), a theological statement submitted to the States General of the Netherlands. This expressed an attempt to moderate the doctrines of Calvinism related to its interpretation of predestination. The Synod of Dort (1618–19) was called by the States General to consider the Five Articles of Remonstrance.

https://en.wikipedia.org/wiki/Aromatic%20compound
Aromatic compound
Aromatic compounds are those chemical compounds (most commonly organic) that contain one or more rings with pi electrons delocalized all the way around them. In contrast to compounds that exhibit aromaticity, aliphatic compounds lack this delocalization. The term "aromatic" was assigned before the physical mechanism determining aromaticity was discovered, and referred simply to the fact that many such compounds have a sweet or pleasant odour; however, not all aromatic compounds have a sweet odour, and not all compounds with a sweet odour are aromatic compounds. Aromatic hydrocarbons, or arenes, are aromatic organic compounds containing solely carbon and hydrogen atoms. The configuration of six carbon atoms in aromatic compounds is called a "benzene ring", after the simple aromatic compound benzene, or a phenyl group when part of a larger compound.

https://en.wikipedia.org/wiki/Antiparticle
Antiparticle
In particle physics, every type of particle is associated with an antiparticle with the same mass but with opposite physical charges (such as electric charge). For example, the antiparticle of the electron is the antielectron (which is often referred to as positron). While the electron has a negative electric charge, the positron has a positive electric charge, and is produced naturally in certain types of radioactive decay. The opposite is also true: the antiparticle of the positron is the electron.

Allosaurus
Allosaurus () is a genus of large carnosaurian theropod dinosaur that lived 155 to 145 million years ago during the Late Jurassic epoch (Kimmeridgian to late Tithonian). The name "Allosaurus" means "different lizard" alluding to its unique (at the time of its discovery) concave vertebrae. It is derived from the Greek () ("different, other") and () ("lizard / generic reptile"). The first fossil remains that could definitively be ascribed to this genus were described in 1877 by paleontologist Othniel Charles Marsh. As one of the first well-known theropod dinosaurs, it has long attracted attention outside of paleontological circles.

Atanasoff–Berry computer
The Atanasoff–Berry computer (ABC) was the first automatic electronic digital computer. Limited by the technology of the day, and execution, the device has remained somewhat obscure. The ABC's priority is debated among historians of computer technology, because it was neither programmable, nor Turing-complete. Conventionally, the ABC would be considered the first electronic ALU (arithmetic logic unit) which is integrated into every modern processor's design.

Ancylopoda
Ancylopoda is a group of browsing, herbivorous, mammals in the Perissodactyla that show long, curved and cleft claws. Morphological evidence indicates the Ancylopoda diverged from the tapirs, rhinoceroses and horses (Euperissodactyla) after the Brontotheria, however earlier authorities such as Osborn sometimes considered the Ancylopoda to be outside Perissodactyla or, as was popular more recently, to be related to Brontotheria.

Ammonia is a compound of nitrogen and hydrogen with the formula NH3. A stable binary hydride, and the simplest pnictogen hydride, ammonia is a colourless gas with a distinct pungent smell. It is a common nitrogenous waste, particularly among aquatic organisms, and it contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to 45 percent of the world's food and fertilizers. Ammonia, either directly or indirectly, is also a building block for the synthesis of many pharmaceutical products and is used in many commercial cleaning products. It is mainly collected by downward displacement of both air and water.

Albertosaurus
Albertosaurus (; meaning "Alberta lizard") is a genus of tyrannosaurid theropod dinosaurs that lived in western North America during the Late Cretaceous Period, about 71 million years ago. The type species, A. sarcophagus, was apparently restricted in range to the modern-day Canadian province of Alberta, after which the genus is named, although an indeterminate species ("cf. Albertosaurus sp.") has been discovered in the Corral de Enmedio and Packard Formations in Mexico. Scientists disagree on the content of the genus, with some recognizing Gorgosaurus libratus as a second species.

https://en.wikipedia.org/wiki/Alphorn
Alphorn
The alphorn or alpenhorn or alpine horn is a labrophone, consisting of a straight several-meter-long wooden natural horn of conical bore, with a wooden cup-shaped mouthpiece. Traditionally the Alphorn was made of one single piece, or two parts at most, and made from the wood of a red pine tree. Sometimes the trees would bend from the weight of snow during the wintertime, and this caused them to have the larger and bent mouthpiece at their ends. Modern Alphorns are sometimes made from three distinct parts that can be stuck together, this is to make them easier to transport via automobile, or even carried by hand, and today are more frequently made from the wood of a spruce tree or fir tree. It is used by mountain dwellers in the Swiss Alps. Similar wooden horns were used for communication in most mountainous regions of Europe, from the Alps to the Carpathians. Alphorns are today used as musical instruments.
