Evangelista Torricelli
Evangelista Torricelli ( ; ; 15 October 160825 October 1647) was an Italian people, Italian physicist and mathematician, and a student of Benedetto Castelli. He is best known for his invention of the barometer, but is also known for his advances in optics and work on the method of indivisibles. The torr is named after him. Biography Early life Torricelli was born on 15 October 1608 in Rome, the firstborn child of Gaspare Ruberti and Giacoma Torricelli. His family was from Faenza in the Province of Ravenna, then part of the Papal States. His father was a textile worker and the family was very poor. Seeing his talents, his parents sent him to be educated in Faenza, under the care of his uncle, Giacomo (James), a Camaldolese monk, who first ensured that his nephew was given a sound basic education. He then entered young Torricelli into a Jesuit College in 1624, possibly the one in Faenza itself, to study mathematics and philosophy until 1626, by which time his father, Gaspare, had di ...

Robert Torricelli
Robert Guy Torricelli (born August 27, 1951) is an American attorney and former politician. A Democrat, Torricelli served as a member of the U.S. House of Representatives from New Jersey's 9th district from 1983 to 1997 and as a United States senator from New Jersey from 1997 to 2003. He is notable for his tenure as chair of the Democratic Senatorial Campaign Committee. In September 2002, Torricelli ended his Senate re-election campaign after having been formally admonished by the U.S. Senate in connection with a campaign finance scandal.

Torricelli Languages
The Torricelli languages are a family of about fifty languages of the northern Papua New Guinea coast, spoken by about 80,000 people. They are named after the Torricelli Mountains. The most populous and best known Torricelli language is Arapesh, with about 30,000 speakers. They are not clearly related to other Papuan language families; however, attempts have been made to establish external links. The most promising external relationship for the Torricelli family is the Sepik languages. (In reconstructions of both families, the pronouns have a plural suffix ''*-m'' and a dual suffix ''*-p''.) C.L. Voorhoeve (1987) has proposed that they are related to the North Halmahera languages and most of the languages of the Bird’s Head Peninsula, thus forming the easternmost extension of the postulated West Papuan family. History The Torricelli languages occupy three geographically separated areas, evidently separated by later migrations of Sepik-language speakers several centuries ...

Torricelli's Law
Torricelli's law, also known as Torricelli's theorem, is a theorem in fluid dynamics relating the speed of fluid flowing from a hole to the height of fluid above the hole. The law states that the speed v of efflux of a fluid through a sharp-edged hole in the wall of the tank filled to a height h above the hole is the same as the speed that a body would acquire in falling freely from a height h, v = \sqrt where g is the Gravity of Earth, acceleration due to gravity. This expression comes from equating the kinetic energy gained, \tfrac mv^2, with the potential energy lost, mgh, and solving for v. The law was discovered (though not in this form) by the Italian scientist Evangelista Torricelli, in 1643. It was later shown to be a particular case of Bernoulli's principle. Derivation Under the assumptions of an Incompressible flow, incompressible fluid with negligible viscosity, Bernoulli's principle states that the hydraulic energy is uniform :\frac + \frac + g y_1 = \frac + \fra ...

Torricelli's Experiment
Torricelli's experiment was invented in Pisa in 1643 by the Italian scientist Evangelista Torricelli (1608-1647). The purpose of his experiment is to prove that the source of Horror vacui (physics), "horror of the vacuum" by nature comes from atmospheric pressure. Context For much of human history, the pressure of gases like air was ignored, denied, or taken for granted, but as early as the 6th century BC, Greek philosopher Anaximenes of Miletus, Anaximenes of Miletus claimed that all things are made of air that is simply changed by varying levels of pressure. He could observe water evaporating and changing to a gas and felt that this applied even to solid matter. More condensed air made colder, heavier objects, and expanded air made lighter, hotter objects. This was akin to how gases become less dense when warmer and more dense when cooler. Aristotle stated in some writings that "nature abhors a vacuum" and also that air has no mass/weight. The popularity of that philosopher k ...

Torricelli's Equation
In physics, Torricelli's equation, or Torricelli's formula, is an equation created by Evangelista Torricelli to find the final velocity of a moving object with constant acceleration along an axis (for example, the x axis) without having a known time interval. The equation itself is: : v_f^2 = v_i^2 + 2a\Delta x \, where *v_f is the object's final velocity along the x axis on which the acceleration is constant. *v_i is the object's initial velocity along the x axis. *a is the object's acceleration along the x axis, which is given as a constant. *\Delta x \, is the object's change in position along the x axis, also called displacement. In this and all subsequent equations in this article, the subscript x (as in _x) is implied, but is not expressed explicitly for clarity in presenting the equations. This equation is valid along any axis on which the acceleration is constant. Derivation Without differentials and integration Begin with the following relations for the case ...

Torricelli (crater)
Torricelli is a lunar impact crater in the eastern part of the Sinus Asperitatis, to the south of the Mare Tranquillitatis. It was named after Italian physicist Evangelista Torricelli. The western rim of the crater is broken open and joined to a smaller crater to the west. The entire formation has a pear-shaped appearance. Torricelli lies in the northeastern part of a circular formation of rises in the lunar mare, possibly the remains of a crater formation buried by lava. Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Torricelli.

Torricelli Act
The Cuban Democracy Act (CDA), also known as the Torricelli Act or the Torricelli-Graham Bill, was a bill introduced and sponsored by U.S. Congressman Robert Torricelli and aimed to tighten the U.S. embargo on Cuba. It reimplemented the ban of U.S. subsidiaries in other countries from trading with Cuba, hindered the ability for ships docked within Cuban ports to travel to U.S. ports, and worked to circumvent other aspects of the embargo to provide humanitarian aid to Cuba in an attempt to draw the Cuban people closer to the United States. The act was passed as "A bill to promote U.S. intervention through the application of sanctions directed at the Castro government and support for the Cuban people." Congressman Torricelli stated that the act was intended to "wreak havoc on that island." Context Since Fidel Castro flocked into the embrace of the Soviets for economic stronghold after the Cuban Missile Crisis, the United States worked to cripple the Cuban economy and destabilize ...

Fermat Point
In Euclidean geometry, the Fermat point of a triangle, also called the Torricelli point or Fermat–Torricelli point, is a point such that the sum of the three distances from each of the three vertices of the triangle to the point is the smallest possible or, equivalently, the geometric median of the three vertices. It is so named because this problem was first raised by Fermat in a private letter to Evangelista Torricelli, who solved it. The Fermat point gives a solution to the geometric median and Steiner tree problems for three points. Construction The Fermat point of a triangle with largest angle at most 120° is simply its first isogonic center or X(13), which is constructed as follows: # Construct an equilateral triangle on each of two arbitrarily chosen sides of the given triangle. # Draw a line from each new vertex to the opposite vertex of the original triangle. # The two lines intersect at the Fermat point. An alternative method is the following: # On each of two ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torricelli Mountains
The Torricelli Mountains are a mountain range in Sandaun Province, north-western Papua New Guinea. The highest peak in the range is Mount Sulen at 1650 meters. The Bewani Mountains are located to the west, and the Prince Alexander Mountains are located to the east. To the north, the mountains slope down to the Pacific Ocean, and to the south lies the basin of the Sepik River. The mountains are named after the Italian physicist and mathematician Evangelista Torricelli during the German colonial period. Dozens of Torricelli languages are spoken within this mountain range. Ecology The portion of the range above 1000 meters elevation is home to the Northern New Guinea mountain rain forests ecoregion, which also extends across portions of the neighboring ranges. The slopes below 1000 meters are part of the Northern New Guinea lowland rain and freshwater swamp forests. Two of the most endangered mammals in the world, Scott's tree-kangaroo (''Dendrolagus scottae'') and golden-ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torr
The torr (symbol: Torr) is a Pressure#Units, unit of pressure based on an absolute scale, defined as exactly of a standard atmosphere (unit), atmosphere (101325 Pa). Thus one torr is exactly (≈ ). Historically, one torr was intended to be the same as one "millimetre of mercury", but subsequent redefinitions of the two units of measurement, units made the torr marginally lower (by less than 0.000015%). The torr is not part of the International System of Units (SI). Even so, it is often combined with the metric prefix milli to name one millitorr (mTorr), equal to 0.001 Torr. The unit was named after Evangelista Torricelli, an Italian physicist and mathematician who discovered the principle of the barometer in 1644. Nomenclature and common errors The unit name ''torr'' is written in letter case, lower case, while its symbol ("Torr") is always written with an uppercase initial; including in combinations with prefixes and other unit symbols, as in "mTorr" (millitorr) or " ...
