High Quality Content by WIKIPEDIA articles! Wide boy is a British term for a man who lives by his wits, wheeling and dealing. According to the Oxford English Dictionary it is synonymous with spiv. The word `wide` is in this sense means wide-awake or sharp-witted. Newspapers of the late 1940s and 1950s often use both terms in the same article about the same person when dealing with ticket touts, fraudsters and black market traders. It has become more generally used to describe a dishonest trader or a petty criminal who works by guile rather than force.

Urine (from Latin Urina, ae, f.) is a typically sterile (in the absence of a disease condition)liquid by-product of the body that is secreted by the kidneys through a process called urination and excreted through the urethra. Cellular metabolism generates numerous by-products, many rich in nitrogen, that require elimination from the bloodstream. These by-products are eventually expelled from the body in a process known as micturition, the primary method for excreting water-soluble chemicals from the body. These chemicals can be detected and analyzed by urinalysis.

Wilson) is a gauge-invariant observable obtained from the holonomy of the gauge connection around a given loop. In the classical theory, the collection of all Wilson loops contains sufficient information to reconstruct the gauge connection, up to gauge transformation.

Why We Fight is a series of seven war information training films commissioned by the United States government during World War II whose purpose was to show American soldiers the reason for U.S. involvement in the war.

The game is played on a 10x10 board with an extra square in each of the extreme corners where the wizards are placed at the start of the game. The game is laid out like regular chess with the addition of a "champion" in each corner and a "wizard" diagonally behind each champion (see diagram on the right).

High Quality Content by WIKIPEDIA articles! "Son of God" is a phrase which according to most Christian denominations, Trinitarian in belief, refers to the relationship between Jesus and God, specifically as "God the Son". To a minority of Christians, nontrinitarians, the term "Son of God", applied to Jesus in the New Testament, is accepted, while the non-biblical but less ambiguous "God the Son" is not.

High Quality Content by WIKIPEDIA articles! Olfaction (also known as olfactics; adjectival form: "olfactory") is the sense of smell. This sense is mediated by specialized sensory cells of the nasal cavity of vertebrates, and, by analogy, sensory cells of the antennae of invertebrates. Many vertebrates, including most mammals and reptiles, have two distinct olfactory systems—the main olfactory system, and the accessory olfactory system (mainly used to detect pheromones). For air-breathing animals, the main olfactory system detects volatile chemicals, and the accessory olfactory system detects fluid-phase chemicals. For water-dwelling organisms, e.g., fish or crustaceans, the chemicals are present in the surrounding water. Olfaction,...

William Frederick Friedman (September 24, 1891 – November 12, 1969) was a US Army cryptographer who ran the research division of the Army`s Signals Intelligence Service (SIS) in the 1930s, and parts of its follow-on services into the 1950s. In 1940, subordinates of his led by Frank Rowlett broke Japan`s PURPLE cipher, thus disclosing Japanese diplomatic secrets before America`s entrance into World War II.

High Quality Content by WIKIPEDIA articles! The White League was a white paramilitary group started in 1874 that operated to turn Republicans out of office and intimidate freedmen from voting and political organizing. Its first chapter in Grant Parish, Louisiana was made up of many of the Confederate veterans who had participated in the Colfax massacre in April 1873. Chapters were soon founded in other areas of the state and in New Orleans. During the later years of Reconstruction, it was one of the paramilitary groups described as "the military arm of the Democratic Party." Through violence and intimidation, its members reduced Republican voting and contributed to the Democrats` taking over control of the Louisiana Legislature in 1876....

High Quality Content by WIKIPEDIA articles! Uranium-lead is one of the oldest and most refined of the radiometric dating schemes, with a routine age range of about 1 million years to over 4.5 billion years, and with routine precisions in the 0.1-1 percent range. The method relies on two separate decay chains, the uranium series from 238U to 206Pb, with a half-life of 4.47 billion years and the actinium series from 235U to 207Pb, with a half-life of 704 million years. These decay routes occur via a series of alpha (and beta) decays, in which 238U with daughter nuclides undergo eight total alpha and six beta decays whereas 235U with daughters only experience seven alpha and four beta decays.

High Quality Content by WIKIPEDIA articles! Uranium-238 (238U or U-238) is the most common isotope of uranium found in nature. It is not fissile, but is a fertile material: it can capture a slow neutron and after two beta decays become fissile plutonium-239. 238U is fissionable by fast neutrons, but cannot support a chain reaction because inelastic scattering reduces neutron energy below the range where fast fission is probable.

A solstice is an astronomical event that happens twice each year when the Sun`s apparent position in the sky, as viewed from Earth, reaches its northernmost or southernmost extremes. The name is derived from the Latin sol (sun) and sistere (to stand still), because at the solstices, the Sun stands still in declination; that is, the apparent movement of the Sun`s path north or south comes to a stop before reversing direction.
