   To cross a check (Eng. Banking), to draw two parallel transverse lines across the face of a check, with or without adding between them the words ``and company'', with or without the words ``not negotiable'', or to draw the transverse lines simply, with or without the words ``not negotiable'' (the check in any of these cases being crossed generally). Also, to write or print across the face of a check the name of a banker, with or without the words ``not negotiable'' (the check being then crossed specially). A check crossed generally is payable only when presented through a bank; one crossed specially, only when presented through the bank mentioned. [Webster 1913 Suppl.]

   To cross one's path, to oppose one's plans.
   --Macaulay.

1530s, "a marking with a cross," verbal noun from cross (v.). From 1570s as "action of passing across;" 1630s as "place where (a river, a road, etc.) is crossed;" from 1690s as "intersection" (originally of streets). Meaning "action of crossing out by drawing crossed lines through" is from 1650s. Crossing-gate is from 1876.

1. (context rare English) extend or lying across; in a crosswise direction. n. 1 An intersection where roads, lines, or tracks cross 2 A place at which a river, railroad, or highway may be crossed 3 A voyage across a body of water 4 (context architecture English) The volume formed by the intersection of chancel, nave and transepts in a cruciform church; often with a tower or cupola over it 5 Movement into a crossed position. v

2. (present participle of cross English)

1. n. traveling across

2. a shallow area in a stream that can be forded [syn: ford]

Crossing is a 2007 Canadian independent feature film starring Sebastian Spence, Crystal Buble, Bif Naked and Fred Ewanuick. From the writer/director team of Roger Evan Larry and Sandra Tomc.

Crossing is an album by American world music/ jazz group Oregon featuring Ralph Towner, Paul McCandless, Glen Moore, and Collin Walcott which was recorded in 1984 and released on the ECM label. This was the final album recorded with Walcott, released after his death in November 1984.

In quantum field theory, a branch of theoretical physics, crossing is the property of scattering amplitudes that allows antiparticles to be interpreted as particles going backwards in time.

Crossing states that the same formula that determines the S-matrix elements and scattering amplitudes for particle A to scatter with X and produce particle B and Y will also give the scattering amplitude for $\scriptstyle \mathrm{A}+\bar{\mathrm{B}}+\mathrm{X}$ to go into Y, or for $\scriptstyle \bar{\mathrm{B}}$ to scatter with $\scriptstyle \mathrm{X}$ to produce $\scriptstyle \mathrm{Y}+\bar{\mathrm{A}}$. The only difference is that the value of the energy is negative for the antiparticle.

The formal way to state this property is that the antiparticle scattering amplitudes are the analytic continuation of particle scattering amplitudes to negative energies. The interpretation of this statement is that the antiparticle is in every way a particle going backwards in time.

Crossing was already implicit in the work of Feynman, but came to its own in the 1950s and 1960s as part of the analytic S-matrix program.

A crossing, in ecclesiastical architecture, is the junction of the four arms of a cruciform (cross-shaped) church.

In a typically oriented church (especially of Romanesque and Gothic styles), the crossing gives access to the nave on the west, the transept arms on the north and south, and the choir, as the first part of the chancel, on the east.

The crossing is sometimes surmounted by a tower or dome. A large crossing tower is particularly common on English Gothic cathedrals. With the Renaissance, building a dome above the crossing became popular. Because the crossing is open on four sides, the weight of the tower or dome rests heavily on the corners; a stable construction thus required great skill on the part of the builders. In centuries past, it was not uncommon for overambitious crossing towers to collapse. Sacrist Alan of Walsingham's octagon, built between 1322 and 1328 after the collapse of Ely's nave crossing on 22 February 1322, is the "... greatest individual achievement of architectural genius at Ely Cathedral" according to architectural historian Nikolaus Pevsner.

A tower over the crossing may be called a lantern tower if it has openings through which light from outside can shine down to the crossing.

In Early Medieval churches, the crossing square was often used as a module, or a unit of measurement. The nave and transept would have lengths that were a certain multiple of the length of the crossing square. This was to ensure that the church was properly proportioned.

Crossing (also known as Keurosing) is a 2008 South Korean film directed by Kim Tae-kyun. It has been selected as South Korea's submission to the 81st Academy Awards for Best Foreign Language Film. The film follows the journey of a North Korean man as he illegally leaves the country to find medicine for his sick wife, portraying the many hardships of the average North Korean citizen. The film had 907,255 admissions in South Korea.

The politics of North Korea in this film are left behind and are mainly in the background. Instead it concentrates more on the life of the average North Korean, such as the hardship in an impoverished state and the fear of getting caught and being persecuted in North Korea. Subtle themes include religion, which runs through the film, as Yong Soo hopes that his son comes back safely, as well as football which is a way in connecting the North Koreans to the outside world.
