A barber's pole is a kind of mark used by barbers to mark the place or shop where they do their craft. The trademark is, by tradition derived from the Middle Ages, sticks or columns with colored stripes of helix (often red and white in many countries, but usually red, blue, and white in the United States). The poles may be stationary or can be rotated, often with the help of an electric motor.
A "barber pole" with a helical strip is a familiar sight, and is used as a secondary metaphor to describe objects in many other contexts. For example, if the shaft or lighthouse tower has been painted with a helical line as a daymark, the lighthouse can be described as having been painted with a "barber pole" color. Likewise, borders can be flagged and warnings highlighted.

Origin in barbering and operations
During the middle ages, barbers performed operations on customers, as well as tooth extractions. The original mast has a brass sink at the top (representing the ship where the leech is stored) and the bottom (representing the hollow that receives the blood). The pole itself represents the staff that the patient holds during the procedure to encourage blood flow.
At the Tour Council in 1163, the clergy were forbidden to practice. From then on, doctors were clearly separated from the surgeon and the barber. Later, the role of the barber was defined by the College de Saint-CÃÆ''me et Saint-Damien, founded by Jean Pitard in Paris around 1210, as an academic surgeon from a long robe and short robber robber.
After the formation of United Barber Surgeon's Company in England, the law requires barbers to use blue and white poles and surgeons to use the red pole. In France, the surgeon uses a red pole with a fitted basin to identify their office. Blue often appears at the poles in the United States, perhaps as a tribute to its national colors. Another more fantastic interpretation of the colors of barber poles is that red represents arterial blood, blue is a symbol of venous blood, and white describes bandages.
Prior to 1950, there were four barber pole producers in the United States. In 1950, William Marvy of St. Paul, Minnesota, began producing barber poles. Marvy made a 50,000 barber pole in 1967, and, in 2010, more than 82,000 have been produced. William Marvy Company is now the only barber pole producer in North America, and sells only 500 per year (compared to 5,100 in the 1960s). In recent years, spinner pole sales have dropped dramatically, as some barber shops open up, and many jurisdictions forbid moving signs. Koken St. Koken Louis, Missouri, produces barber tools such as chairs and various poles in the 19th century.
In early 1905, polar use was reported to be "diminished" in the United States.
In Forest Grove, Oregon, "The Tallest Pole Shop Shop in the World" measures 72 feet (22 m).
The consistent use of this symbol for advertising is analogous to the pharmacist's show world, tobacco cigar shop in India and three golden pawnbrooks.

Use in barbering
The red and white poles outside the barber shop refer to the time when the barber is expected to commit bloodshed and other medical procedures to heal the sick; red may represent blood and white may be bandages. Perhaps as early as the later Roman Empire, and certainly continue through the Renaissance into Industrialization (possibly even until the 1700s in some places) "barber-surgery" also performed tooth extraction, cupping, leeching, bloodshed, enema, amputation, etc.. However, the barber poles currently represent little more than a barber shop that cuts hair and shaves. Barber poles have actually become a topic of controversy in the hairstyling business. In some states, such as Michigan in March 2012, legislation has emerged suggesting that barbers poles should only be allowed outside barbers, but not traditional beauty salons. Barbers and beauticians have been involved in several legal battles claiming the right to use barbender symbols to show potential customers that the business offers hair-cutting services. Barbers claim that they are entitled to exclusive rights to use barbers because tradition is tied to crafts, whereas beauty experts think that they are equally able to cut male hair (although many cosmetic experts are not allowed to use razors, depending on their country's laws ).
Use in prostitution
In South Korea, the barber poles are used both for actual grinding and for brothels. The brothel disguised as a barber, referred to as ??? ( ibalso ) or ??? (miyongsil ), are more likely to use two adjacent poles, often spinning in the opposite direction, although the use of a single pole for the same reason is also quite common. Real snack, or ??? ( miyongsil ), more likely to be a hair salon; To avoid confusion, they will usually use a pole that shows a picture of a woman with hair flowing over it with the words hair salon written on the pole.
Visual illusions
Spinning spinning poles create a visual illusion, where lines appear to move up or down along the poles, not around them.
Other uses of the term
Visual similarity
- The Goose Section M17, Omega Nebula in Sagittarius flexibility is said to resemble a barber pole.
- The barber pole-like structure has been observed at the cellular level. The effects, origins and causes are controversial, and subject to intense research.
- The Matthew Walker knot is a decorative knot that is said to be similar to a barber bar.
- Sinosauropteryx (meaning "Chinese reptile wing", in Chinese: zhonghua longniao) is the first non-avian dinosaur genus to be found with fossil traces of feathers, as well as non- the first poultry in which the coloring has been determined. It lived in China during the early Cretaceous period and was a close relative of Compsognathus . This is the first non-avian dinosaur genus found from the famous Biota Jehol in Liaoning Province. Zhang found "that the filaments flowing on their backs and tails may have made dinosaurs look like orange and white pruning columns." The pattern is so vivid that 'feathers first appeared as agents for color display,' said Benton. li>

Computer science
In UI design, patterns such as barber poles are used in the progress bar when waiting times are not specified. This is meant to be used like a flick to notify the user that processing is in progress, though it is not known when the processing will complete.
Barber pole is also sometimes used to describe text patterns where text lines are rolled to the left or right of a character on the line below. The CHARGEN service generates this pattern. This is used to test RAM, hard disk and printer. A similar pattern is also used in secure media removal.
Electronics
The strength and direction of the magnetic field and electric current can be measured using a "barber-pole magnetoresistive sensor" (also called "hermetic proximity sensor"), and its performance can be illustrated using mathematical formulas. Such sensors interleaves a series of permanent magnet strips with a series of magnetoresistive strips. "The conductive barberpole strips are tilted in the sensor and connect one magnetoresistive strip, above the permanent magnet strip, to another magnetoresistive strip." This is said to provide a "uniform magnetic field across the sensor" thereby increasing its resistance to the external magnetic field. This technology is used in wireless sensor networks that "have garnered much attention as an important research domain" and "used in many applications, such as , navigation, military, ambient, medical, intelligence and industrial tasks. context-based services, in the context of specific locations, are of primary importance... "(See Music (acoustic illusion), infra.)
Aerospace and space flight
The term on a barber pole is a pilot jargon that refers to flying a plane at maximum safe speed. The air velocity indicator on a plane capable of flying at altitudes has a red/white striped needle resembling a barber pole. This needle displays the V MO (Maximum Operating Speed) or - at the height - M MO (Mach Limit Maximum Operating Speed) from the plane. This needle also shows the maximum number of Machs above the VMO/MMO changeover level. As the aircraft increases in height and air decreases in density and temperature, the speed of sound also decreases. Close to the speed of sound, the aircraft becomes vulnerable to pounding caused by shock waves generated by flying at transonic speeds. Thus, the sound speed decreases, so that the maximum safe operating speed of the aircraft is reduced. The needle "pole bar" moves to show this speed. Fly "in a barber pole" because it means flying a plane as fast as it is safe to do so in its current state.
Barberpole is the phrase used to describe the striped output of the indicators used during Apollo and Shuttle programs. Usually the indicator will show all the gray or gray striped patterns and white, known as the barberpole, to allow the astronauts a quick visual reference of the status of the spacecraft system. The various indicators in the Apollo Command Module show the barberpole when the system is inactive. Astronaut Jim Lovell can also be found describing the system indication as "barber poled" in radio transcript transcripts during the Apollo 13 crash.
The phrase barberpole continues to be found in many subsystem descriptions in the Space Shuttle News Reference Manual , as well as the NASA/KSC Acronym List.
During World War I and World War II, this pattern has also been used as a symbol of aircraft identification. Spad XIIIs of the Aero Squadron 94th USAS in early 1919 used a variety of trimmer pole patterns including: 'Barber Pole' from Lt Dudley 'Red' Outcault; S.16546 'Flag Bus' from Captain Reed Chambers; and 'Rising Sun' from Lt John Jeffers.

Parachuting
The Commander Parachute Demonstration Team, operating outside Fort Campbell, Kentucky, runs a "barber pole maneuver" (also known as "the Baton Pass") during the demonstration. Two jumpers leave the plane and fly their bodies together to connect when it falls freely. "After together they will exchange wooden sticks... [and] maneuver their bodies... to create the illusion of a giant barber pole in the sky."Meteorology
- According to the National Oceanic and Atmospheric Administration, barber pole is a slang term used by storm observers and storms to describe "an updraft of lightning storms with visual displays including a curved cloud of clouds by way of which is similar to the lines of the barber bar.The structure is usually most prominent on the main edge of the updraft, while the dry air from the downdraft of the rear side often erodes clouds on the back side of the updraft. "See Supercell. Photo pole supercell/barber.
- A lynchpin from the Hurricane National Research Laboratory's hurricane research fleet is Lockheed WP-3D Orion (P-3). It has two polar samplers (called red and white stripes) that stand out from the front of the plane, Doppler tail radar weather, and other unique instruments hanging on the wings.
Booksellers
A red or rubric post is sometimes used by booksellers in the United Kingdom before 1800. William Roberts reports on The Book Hunter in London that certain 18th century bookshops in the Little Britain district of London use poles like that:
A few years before Nichols published [in 1816] his book Anecdote Sastra, two booksellers used to post their rubric close to each other here in Little Britain, and posting this rubric ever as many types of bookstores as the pole seller was from a barber. Sewell, Cornhill, and Kecket and De Hondt, Strand, are one of the last to use these strange trading signs.
