Heliomera is an extinct genus of trilobite in the order Phacopida. It contains two species. H. albata and H. sol.
Calculus is the mathematical study of continuous change, in the same way that geometry is the study of shape, and algebra is the study of generalizations of arithmetic operations.
In mathematics, the derivative is a fundamental tool that quantifies the sensitivity of change of a function's output with respect to its input. The derivative of a function of a single variable at a chosen input value, when it exists, is the slope of the tangent line to the graph of the function at that point. The tangent line is the best linear approximation of the function near that input value. For this reason, the derivative is often described as the instantaneous rate of change, the ratio of the instantaneous change in the dependent variable to that of the independent variable. The process of finding a derivative is called differentiation.
George Herbert Walker Bush was an American politician, diplomat, and businessman who served as the 41st president of the United States from 1989 to 1993. A member of the Republican Party, he also served as the 43rd vice president from 1981 to 1989 under Ronald Reagan and previously in various other federal positions.
Herbert George Wells was an English writer, prolific in many genres. He wrote more than fifty novels and dozens of short stories. His non-fiction output included works of social commentary, politics, history, popular science, satire, biography, and autobiography. Wells' science fiction novels are so well regarded that he has been called the "father of science fiction".
H, or h, is the eighth letter of the Latin alphabet, used in the modern English alphabet, including the alphabets of other western European languages and others worldwide. Its name in English is aitch, or regionally haitch, plural haitches.
Howard Phillips Lovecraft was an American writer of weird, science, fantasy, and horror fiction. He is best known for his creation of the Cthulhu Mythos.
In chemistry, pH, also referred to as acidity or basicity, historically denotes "potential of hydrogen". It is a logarithmic scale used to specify the acidity or basicity of aqueous solutions. Acidic solutions are measured to have lower pH values than basic or alkaline solutions.
Quantum mechanics is a fundamental theory that describes the behavior of nature at and below the scale of atoms. It is the foundation of all quantum physics, which includes quantum chemistry, quantum field theory, quantum technology, and quantum information science.
A magnetic field is a physical field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field. A permanent magnet's magnetic field pulls on ferromagnetic materials such as iron, and attracts or repels other magnets. In addition, a nonuniform magnetic field exerts minuscule forces on "nonmagnetic" materials by three other magnetic effects: paramagnetism, diamagnetism, and antiferromagnetism, although these forces are usually so small they can only be detected by laboratory equipment. Magnetic fields surround magnetized materials, electric currents, and electric fields varying in time. Since both strength and direction of a magnetic field may vary with location, it is described mathematically by a function assigning a vector to each point of space, called a vector field.
Atmospheric pressure, also known as air pressure or barometric pressure, is the pressure within the atmosphere of Earth. The standard atmosphere is a unit of pressure defined as 101,325 Pa (1,013.25 hPa), which is equivalent to 1,013.25 millibars, 760 mm Hg, 29.9212 inches Hg, or 14.696 psi. The atm unit is roughly equivalent to the mean sea-level atmospheric pressure on Earth; that is, the Earth's atmospheric pressure at sea level is approximately 1 atm.
M*A*S*H is an American war comedy drama television series that aired on CBS from September 17, 1972, to February 28, 1983. It was developed by Larry Gelbart as the first original spin-off series adapted from the 1970 feature film M*A*S*H, which, in turn, was based on Richard Hooker's 1968 novel MASH: A Novel About Three Army Doctors. The series, produced by 20th Century Fox Television for CBS, follows a team of doctors and support staff stationed at the "4077th Mobile Army Surgical Hospital" in Uijeongbu, South Korea, during the Korean War (1950–53).
Helicobacter pylori, previously known as Campylobacter pylori, is a gram-negative, flagellated, helical bacterium. Mutants can have a rod or curved rod shape that exhibits less virulence. Its helical body is thought to have evolved to penetrate the mucous lining of the stomach, helped by its flagella, and thereby establish infection. The bacterium was first identified as the causal agent of gastric ulcers in 1983 by Australian physician-scientists Barry Marshall and Robin Warren. In 2005, they were awarded the Nobel Prize in Physiology or Medicine for their discovery.
H & M Hennes & Mauritz AB, commonly known by its brand name H&M, is a multinational fashion retailer headquartered in Stockholm, Sweden.
Paul Michael Levesque, better known by the ring name Triple H, is an American business executive, actor, and retired professional wrestler. Regarded as one of the greatest professional wrestlers of all time, he is the Chief Content Officer for WWE, a subsidiary of TKO Group Holdings.
Stephanie Marie McMahon Levesque is an American businesswoman and retired professional wrestler. She is known for her various roles within WWE between 1998 and 2023.
Homo is a genus of great ape that emerged from the genus Australopithecus and encompasses only a single extant species, Homo sapiens, along with a number of extinct species classified as either ancestral or closely related to modern humans; these include Homo erectus and Homo neanderthalensis. The oldest member of the genus is Homo habilis, with records of just over 2 million years ago. Homo, together with the genus Paranthropus, is probably most closely related to the species Australopithecus africanus within Australopithecus. The closest living relatives of Homo are of the genus Pan, with the ancestors of Pan and Homo estimated to have diverged around 5.7-11 million years ago during the Late Miocene.
The WWE Championship is a men's professional wrestling world heavyweight championship created and promoted by the American promotion WWE, defended on the SmackDown brand division. Since April 2022, the title has been jointly held and defended with the WWE Universal Championship as the Undisputed WWE Championship, but both titles have maintained their individual lineages. It is one of three world titles in WWE, alongside its companion Universal Championship on SmackDown, and the World Heavyweight Championship on Raw. The current champion is Cody Rhodes, who is in his first reign. He won the undisputed title by defeating previous champion Roman Reigns in a Bloodline Rules match at WrestleMania XL Night 2 on April 7, 2024.
Cheiruridae is a family of phacopid trilobites of the suborder Cheirurina. Its members, as with other members of the suborder, had distinctive pygidial modified into finger-like spines. They first appeared in the uppermost Cambrian, and persisted until the end of the Middle Devonian (Givetian). Currently about 657 species assigned to 99 genera are included.
Heliomeroides is a trilobite in the order Phacopida, that existed during the upper Ordovician in what is now the United States. It was described by Evitt in 1951, and the type species is Heliomeroides teres. The type locality was the Lincolnshire Formation in Virginia.
The Planck constant, or Planck's constant, denoted by , is a fundamental physical constant of foundational importance in quantum mechanics: a photon's energy is equal to its frequency multiplied by the Planck constant, and the wavelength of a matter wave equals the Planck constant divided by the associated particle momentum. The closely related reduced Planck constant, equal to and denoted is commonly used in quantum physics equations.
