In theoretical physics, a Feynman diagram is a pictorial representation of the mathematical expressions describing the behavior and interaction of subatomic particles. The scheme is named after American physicist Richard Feynman, who introduced the diagrams in 1948. The interaction of subatomic particles can be complex and difficult to understand; Feynman diagrams give a simple visualization of what would otherwise be an arcane and abstract formula. According to David Kaiser, "Since the middle of the 20th century, theoretical physicists have increasingly turned to this tool to help them undertake critical calculations. Feynman diagrams have revolutionized nearly every aspect of theoretical physics." While the diagrams are applied primarily to quantum field theory, they can also be used in other areas of physics, such as solid-state theory. Frank Wilczek wrote that the calculations that won him the 2004 Nobel Prize in Physics "would have been literally unthinkable without Feynman diagrams, as would [Wilczek's] calculations that established a route to production and observation of the Higgs particle."
Half-life is the time required for a quantity to reduce to half of its initial value. The term is commonly used in nuclear physics to describe how quickly unstable atoms undergo radioactive decay or how long stable atoms survive. The term is also used more generally to characterize any type of exponential decay. For example, the medical sciences refer to the biological half-life of drugs and other chemicals in the human body. The converse of half-life is doubling time.
A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. The reverse operation is performed by an inverter.
Radioactive decay 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 decay. The weak force is the mechanism that is responsible for beta decay, while the other two are governed by the electromagnetism and nuclear force.
A galvanic cell or voltaic cell, named after the scientists Luigi Galvani and Alessandro Volta, respectively, is an electrochemical cell in which an electric current is generated from spontaneous Oxidation-Reduction reactions. A common apparatus generally consists of two different metals, each immersed in separate beakers containing their respective metal ions in solution that are connected by a salt bridge or separated by a porous membrane.
A quantity is subject to exponential decay if it decreases at a rate proportional to its current value. Symbolically, this process can be expressed by the following differential equation, where N is the quantity and λ (lambda) is a positive rate called the exponential decay constant, disintegration constant, rate constant, or transformation constant:
The Mississippi River Alluvial Plain is an alluvial plain created by the Mississippi River on which lie parts of seven U.S. states, from southern Louisiana to southern Illinois.
In sports, a winning percentage is the fraction of games or matches a team or individual has won. The statistic is commonly used in standings or rankings to compare teams or individuals. It is defined as wins divided by the total number of matches played. A draw counts as a 1⁄2 win.
Thorium (90Th) has seven naturally occurring isotopes but none are stable. One isotope, 232Th, is relatively stable, with a half-life of 1.405×1010 years, considerably longer than the age of the Earth, and even slightly longer than the generally accepted age of the universe. This isotope makes up nearly all natural thorium, so thorium was considered to be mononuclidic. However, in 2013, IUPAC reclassified thorium as binuclidic, due to large amounts of 230Th in deep seawater. Thorium has a characteristic terrestrial isotopic composition and thus a standard atomic weight can be given.
Biological half-life is the time taken for concentration of a biological substance to decrease from its maximum concentration (Cmax) to half of Cmax in the blood plasma. It is denoted by the abbreviation .
Garrowhill railway station serves the Garrowhill and Barlanark areas of Glasgow, Scotland. The railway station is 4¾ miles (7 km) east of Glasgow Queen Street railway station on the North Clyde Line and is managed by ScotRail.
Wetarese is an Austronesian language of Wetar, an island in the south Maluku, Indonesia, and of the nearby islands Liran and Atauro, the latter island separate from the mainland of East Timor, north of Dili.
The United Provinces of Armagh and Tuam, commonly called the Province of Armagh, and also known as the Northern Province, is one of the two ecclesiastical provinces that together form the Anglican Church of Ireland; the other is the Province of Dublin. The province has existed since 1833, when the ancient Province of Armagh was merged with the Province of Tuam. The Archbishop of Armagh is its metropolitan bishop.
Ghanongga, or Ganoqa, is an Oceanic language spoken by about 2,500 people on the northern half of Ranongga Island, Solomon Islands.
The 1892 Boston Beaneaters season was the 22nd season of the franchise. The Beaneaters won their second straight and fifth overall National League pennant. In the league's first split season, the Beaneaters finished first in the first half, and three games behind the Cleveland Spiders in the second half. After the season, the two teams played a "World's Championship Series", which the Beaneaters won, five games to none. The National League did not play another split season until 1981.
In geometry, the major axis of an ellipse is its longest diameter: a line segment that runs through the center and both foci, with ends at the two most widely separated points of the perimeter. The semi-major axis is the longest semidiameter or one half of the major axis, and thus runs from the centre, through a focus, and to the perimeter. The semi-minor axis of an ellipse or hyperbola is a line segment that is at right angles with the semi-major axis and has one end at the center of the conic section. For the special case of a circle, the lengths of the semi-axes are both equal to the radius of the circle.
SS Thesis was a steamship which was wrecked in October 1889 in the Sound of Mull, on Scotland's west coast. She is now a popular dive site with scuba divers.
Esmirtazapine (ORG-50,081) is a tetracyclic antidepressant drug that was under development by Organon for the treatment of insomnia and vasomotor symptoms (e.g., hot flashes) associated with menopause. Esmirtazapine is the (S)-(+)-enantiomer of mirtazapine and possesses similar overall pharmacology, including inverse agonist actions at H1 and 5-HT2 receptors and antagonist actions at α2-adrenergic receptors.
Keihin is a Japanese automotive and motorcycle parts brand of Hitachi Astemo. At the past times, Keihin was a major supplier to Honda, who owned nearly half of Keihin's shares, but also supplies other motorcycle manufacturers, among them Triumph, Suzuki, Kawasaki, KTM, Royal Enfield and Harley-Davidson. In addition to carburetors, Keihin supplies the automotive industry with engine, transmission, and climate control products, including intake manifold assemblies, HVAC assemblies, compressors, valves, solenoids, and engine control units.
