Robin Hood is the semi-legendary English medieval outlaw reputed to have robbed the rich and helped the poor. In this expression, Robin Hood's barn represents an out-of-the-way place of a kind that might be used by an outlaw or fugitive such as Robin Hood. Recorded from the mid 19th century, the phrase seems to have originated in the dialect speech of the English Midlands, the area in which Robin Hood is said to have operated.See also: barn, robin, roundcan’t hit the (broad) side of a barn tv. cannot aim something accurately.

See also: borncan't hit the broad side of a barnDescribing a person with very poor aim. The term is thought to have originated in the mid-nineteenth century in the military. It was often repeated in the early twentieth century, when it was applied to untalented baseball pitchers who could not throw the ball over the plate with any consistency. The “broad side” in this expression also suggests the old naval meaning of broadside, that is, a simultaneous discharge of all the guns on one side of a warship. However, there are numerous variants (the inside of a barn, the right side of a barn with a shotgun, and so on) that suggest the term may also have been rural in origin.See also: barn, broad, hit, of, sidelock the barn/stable door after the horse has bolted/is stolen, toTo take precautions after damage has been done. This proverb, found in many languages, first appeared in a French collection of ca. 1190 and found its way into a Middle English manuscript, Douce MS, by about 1350. It has been repeated ever since. Stanley Walker poked fun at it (The Uncanny Knacks of Mr. Doherty, 1941): “He locked the stable door while they were putting the cart before the horse.”See also: after, barn, bolt, door, horse, lock, stablecouldn't hit the side of a barnA lousy shot. This useful phrase can be applied to baseball pitchers who can't get the ball over the plate, basketball players who miss free throws, golfers whose balls routinely go out of bounds, target shooters and archers who miss the target, and anyone else who can't get it right. Another similar farm-based expression is “couldn't hit a bull's ass with a barn shovel.”See also: barn, hit, of, sidebarn

Atomic nuclei are composed of two types of particles, protons and neutrons, which are collectively known as nucleons.

The barn is approximately the size of the geometric cross section of an atomic nucleus; the term was coined because an effective cross section that large would present a target "as big as a barn," i.e., an easy target for nuclear bombardment. In practice, effective cross sections of nuclei for many reactions are measured in millibarns (10−3 barn) because, for most interactions, only a small fraction of collisions cause reactions.BarnA building for housing animals and storing farm equipment, hay, and other agricultural produce.   Barn a unit of effective cross-sectional area of nuclear processes. One barn = 10–24 cm2 = 10–28 m2. Selection of this unit is related to the fact that the geometric cross sections of atomic nuclei are on the order of 10–24 cm2 in size. The magnitudes of the majority of cross sections of nuclear reactions usually lie in the range between 10–22 cm2 and 10–27cm2. For this reason fractional and multiple barn units are used, such as millibarn (10–27 cm2), microbarn (10–30 cm2), and megabarn (10–18 cm2). barn[′bärn] (agriculture) A farm building used for storage of agricultural products and equipment or for housing farm animals. (nuclear physics) A unit of area equal to 10-24 square centimeter; used in specifying nuclear cross sections. Symbolized b. barnA farm building, most often rectangular (but occasionally circular or polygonal), for housing farm animals, storing farm equipment, threshing grain, and storing grain, hay, and other agricultural produce. Barn construction usually depends on such factors as the local climate and traditions, building materials available, the skills and time required for construction, and the cost. For some examples, see bank barn, basement barn, circular barn, connected barn, Connecticut barn, crib barn, double barn, Dutch barn, English barn, forebay barn, four-crib barn, German barn, hex barn, New England connected barn, octagon barn, Pennsylvania barn, Pennsylvania Dutch barn, potato barn, raised barn, round barn, side-hill barn, Sweitzer barn, Swiss barn, three-bay barn, tobacco barn, Yankee barn.barn1 US and Canadian a large shed for sheltering railroad cars, trucks, etc.
