Kon-Tiki expedition. The "Kon-Tiki" expedition was a 1947 journey by raft across the Pacific Ocean from South America to the Polynesian islands, led by Norwegian explorer and writer Thor Heyerdahl. The raft was named "Kon-Tiki" after the Inca god Viracocha, for whom "Kon-Tiki" was said to be an old name. "" is also the name of Heyerdahl's book, the Academy Award–winning 1950 documentary film chronicling his adventures, and the 2012 dramatized feature film nominated for the Academy Award for Best Foreign Language Film.Heyerdahl believed that people from South America could have reached Polynesia during pre-Columbian times. His aim in mounting the "Kon-Tiki.

Kon-Tiki expedition. expedition was to show, by using only the materials and technologies available to those people at the time, that there were no technical reasons to prevent them from having done so. Although the expedition carried some modern equipment, such as a radio, watches, charts, sextant, and metal knives, Heyerdahl argued they were incidental to the purpose of proving that the raft itself could make the journey. This idea has recently received support from statistical analysis of genetic evidence of contact between South America and Polynesia.Heyerdahl's full hypothesis of a South American origin of the Polynesian peoples is generally rejected by.

Kon-Tiki expedition. scientists today. Most archaeological, linguistic, cultural, and genetic evidence tends to support a western origin for Polynesians, from Island Southeast Asia, using sophisticated multihull sailing technologies and navigation techniques during the Austronesian expansion. However, there is evidence of some gene flow from South America to Easter Island. In 2020 some researchers published research confirming a wider impact on genetic and cultural elements in Polynesia due to South American contacts. The "Kon-Tiki" expedition was funded by private loans, along with donations of equipment from the United States Army. Heyerdahl and a small team went to Peru, where, with the help of.

Kon-Tiki expedition. dockyard facilities provided by the Peruvian authorities, they constructed the raft out of balsa logs and other native materials in an indigenous style as recorded in illustrations by Spanish conquistadores. The trip began on April 28, 1947. Heyerdahl and five companions sailed the raft for 101 days over 6,900 km (4,300 miles) across the Pacific Ocean before smashing into a reef at Raroia in the Tuamotus on August 7, 1947. The crew made successful landfall and all returned safely.Thor Heyerdahl's book about his experience became a bestseller. It was published in Norwegian in 1948 as "The Kon-Tiki Expedition: By Raft.

Kon-Tiki expedition. Across the South Seas", later reprinted as "Kon-Tiki: Across the Pacific in a Raft". It appeared with great success in English in 1950, also in many other languages. A documentary motion picture about the expedition, also called "Kon-Tiki", was produced from a write-up and expansion of the crew's filmstrip notes and won an Academy Award in 1951. It was directed by Heyerdahl and edited by Olle Nordemar. The voyage was also chronicled in the documentary TV-series "The Kon-Tiki Man: The Life and Adventures of Thor Heyerdahl", directed by Bengt Jonson.The original "Kon-Tiki" raft is now on display in the Kon-Tiki.

Kon-Tiki expedition. Museum at Bygdøy in Oslo.## Crew."Kon-Tiki" had a six-man crew, all of whom were Norwegian except for Bengt Danielsson, a Swede. Thor Heyerdahl (1914–2002) was the expedition leader. He was also the author of the book of the expedition and the narrator of the story. Heyerdahl had studied the ancient people of South America and Polynesia and believed that there was a link between the two. Erik Hesselberg (1914–1972) was the navigator and artist. He painted the large Kon-Tiki figure on the raft's sail. His children's book "Kon-Tiki and I" appeared in Norwegian in 1949 and has since been published.

Kon-Tiki expedition. in more than 15 languages. Bengt Danielsson (1921–1997) took on the role of steward, in charge of supplies and daily rations. Danielsson was a Swedish sociologist interested in human migration theory. He also served as translator, as he was the only member of the crew who spoke Spanish. He was also a voracious reader; his box aboard the raft contained many books. Knut Haugland (1917–2009) was a radio expert, decorated by the British in World War II for actions in the Norwegian heavy water sabotage that stalled what were believed to be Germany's plans to develop an atomic bomb. Haugland.

Kon-Tiki expedition. was the last surviving crew member; he died on Christmas Day, 2009 at the age of 92. Torstein Raaby (1918–1964) was also in charge of radio transmissions. He gained radio experience while hiding behind German lines during WWII, spying on the German battleship "Tirpitz". His secret radio transmissions eventually helped guide in Allied bombers to sink the ship. Herman Watzinger (1910–1986) was an engineer whose area of expertise was in technical measurements. He was the first to join Heyerdahl for the trip. He collected and recorded all sorts of data on the voyage. Much of what he recorded, such as.

Kon-Tiki expedition. weather data, was sent back to various people, since this area of the ocean was largely unstudied.The expedition also carried a pet parrot named Lorita.## Construction.The main body of the float was composed of nine balsa tree trunks up to 45 (ft) long, 2 (ft) in diameter, lashed together with 1+1/4 (in) hemp ropes. Cross-pieces of balsa logs 18 (ft) long and 1 (ft) in diameter were lashed across the logs at 3 (ft) intervals to give lateral support. Pine splashboards clad the bow, and lengths of pine 1 (in) thick and 2 (ft) wide were wedged between the balsa.

Kon-Tiki expedition. logs and used as centreboards.The main mast was made of lengths of mangrove wood lashed together to form an A-frame 29 (ft) high. Behind the main-mast was a cabin of plaited bamboo 14 (ft) long and 8 (ft) wide, about 4 - 5 (ft) high and roofed with banana leaf thatch. At the stern was a 19 (ft) long steering oar of mangrove wood, with a blade of fir. The main sail was 15 by 18 (ft) on a yard of bamboo stems lashed together. Photographs also show a top-sail above the main sail, and also a mizzen-sail, mounted at.

Kon-Tiki expedition. the stern.The raft was partially decked in split bamboo. The main spars were a laminate of wood and reeds and Heyerdahl tested more than twenty different composites before settling on one that proved an effective compromise between bulk and torsional rigidity. No metal was used in the construction.## Supplies."Kon-Tiki" carried 275 (USgal) of drinking water in 56 water cans, as well as a number of sealed bamboo rods. The purpose stated by Heyerdahl for carrying modern and ancient containers was to test the effectiveness of ancient water storage. For food "Kon-Tiki" carried 200 coconuts, sweet potatoes, bottle gourds and other.

Kon-Tiki expedition. assorted fruit and roots. The U.S. Army Quartermaster Corps provided field rations, tinned food and survival equipment. In return, the "Kon-Tiki" explorers reported on the quality and utility of the provisions. They also caught plentiful numbers of fish, particularly flying fish, "dolphin fish", yellowfin tuna, bonito and shark.Heyerdahl and crew were equipped with water-tight sports wristwatches manufactured by Swiss watchmaking firm Eterna. After the journey, Eterna decided to brand their sports watches as "Kon-Tiki".## Communications.The expedition carried an amateur radio station with the call sign of LI2B operated by former World War II Norwegian resistance radio operators Knut Haugland and.

Kon-Tiki expedition. Torstein Raaby. Haugland and Raaby maintained regular communication with a number of American, Canadian, and South American stations that relayed "Kon Tiki's" status to the Norwegian Embassy in Washington, D.C. On August 5, Haugland made contact with a station in Oslo, Norway, 10000 (mi) away."Kon Tiki's" transmitters were powered by batteries and a hand-cranked generator and operated on the 40, 20, 10, and 6-meter bands. Each unit was water resistant, used 2E30 vacuum tubes, and provided approximately 6 watts of RF output; the equivalent of a small flashlight. Two British 3-16 MHz Mark II transmitters were also carried on board,.

Kon-Tiki expedition. as was a VHF transmitter for communicating with aircraft and a hand-cranked survival radio of the Gibson Girl type for 500 and 8280 kHz.The radio receiver used throughout the voyage, a National Radio Company NC-173, once required a thorough drying out after being soaked when landing in Raratonga. The crew once used a hand-cranked emergency transmitter to send out an "all well, all well" message "just in time to head off a massive rescue attempt".The call sign LI2B was used by Heyerdahl again in 1969–70, when he built a papyrus reed raft and sailed from Morocco to Barbados in an.

To avoid coastal traffic it was initially towed 50 (mi) out by the Peruvian Navy fleet tug "Guardian Rios", then sailed roughly west carried along on the Humboldt Current.On 2 July Heyerdahl writes about an encounter with a rogue wave; in his book he describes a "Three Sister" phenomenon: "During a night-shift with quiet seas appears an 'abnormal huge wave' followed by two more waves. The raft is being swept up and.

Kon-Tiki expedition. down and is covered in water." After the three waves he describes the sea as quiet as before.The crew's first sight of land was the atoll of Puka-Puka on July 30. On August 4, the 97th day after departure, "Kon-Tiki" reached the Angatau atoll. The crew made brief contact with the inhabitants of Angatau Island, but were unable to land safely. Calculations made by Heyerdahl before the trip had indicated that 97 days was the minimum amount of time required to reach the Tuamotus, so the encounter with Angatau showed that they had made good time.On August 7, the voyage.

Kon-Tiki expedition. ended when the raft struck a reef and was then beached on an uninhabited islet off Raroia atoll in the Tuamotus. The team had travelled a distance of around 6980 (km) in 101 days, at an average speed of 1.5 (kn).After spending a number of days alone on the islet, the crew was greeted by men from a village on a nearby island who arrived in canoes, having seen washed-up flotsam from the raft. The crew were taken back to the native village, where they were feted with traditional dances and other festivities. Finally the crew were taken off Raroia.

Kon-Tiki expedition. to Tahiti by the French schooner "Tamara", with the salvaged "Kon-Tiki" in tow.## Anthropology.The basis of the "Kon-Tiki" expedition was pseudoscientific, racially controversial, and has not gained acceptance among scientists (even prior to the voyage). Heyerdahl believed that the original inhabitants of Easter Island (and the rest of Polynesia) were the "Tiki people", a race of "white bearded men" who supposedly originally sailed from Peru. He described these "Tiki people" as being a sun-worshipping fair-skinned people with blue eyes, fair or red hair, tall statures, and beards. He further said that these people were originally from the Middle East, and.

Kon-Tiki expedition. had crossed the Atlantic earlier to found the great Mesoamerican civilizations. By 500 CE, a branch of these people were supposedly forced out into Tiahuanaco where they became the ruling class of the Inca Empire and set out to voyage into the Pacific Ocean under the leadership of "Con Ticci Viracocha".He argued that the monumental statues known as moai resembled sculptures more typical of pre-Columbian Peru than any Polynesian designs. He believed that the Easter Island myth of a power struggle between two peoples called the Hanau epe and Hanau momoko was a memory of conflicts between the original inhabitants.

Kon-Tiki expedition. of the island and a later wave of Native Americans from the Northwest coast, eventually leading to the annihilation of the Hanau epe and the destruction of the island's culture and once-prosperous economy. Heyerdahl described these later migrants as "Maori-Polynesians" who were supposedly Asians who crossed over the Bering land bridge into Northwest America before sailing westward towards Polynesia (the westward direction is because he refused to accept that Polynesians were capable of sailing against winds and currents). He associated them with the Tlingit and Haida peoples and characterized them as "inferior" to the Tiki people.Heyerdahl's hypothesis was part of.

Kon-Tiki expedition. early Eurocentric hyperdiffusionism and the westerner disbelief that (non-white) "stone-age" peoples with "no math" could colonize islands separated by vast distances of ocean water, even against prevailing winds and currents. He rejected the highly skilled voyaging and navigating traditions of the Austronesian peoples and instead argued that Polynesia was settled from boats following the wind and currents for navigation from South America. As such, the "Kon-Tiki" was deliberately a primitive raft and unsteerable, in contrast to the sophisticated outrigger canoes and catamarans of the Austronesian people.Heyerdahl's hypothesis of Polynesian origins is overwhelmingly rejected by scientists today. Archaeological, linguistic, cultural, and.

Kon-Tiki expedition. genetic evidence all support a western origin (from Island Southeast Asia) for Polynesians via the Austronesian expansion. "Drift voyaging" from South America was also deemed "extremely unlikely" in 1973 by computer modeling, although is in contrast with recent genetic analysis. The 1976 voyage of the "Hōkūleʻa", a performance-accurate replica of a Polynesian double-hulled "wa'a kaulua" voyaging canoe, from Hawaiʻi to Tahiti was partly a demonstration to prove that Heyerdahl was wrong. The "Hōkūleʻa" sailed against prevailing winds and exclusively used wayfinding and celestial Polynesian navigation techniques (unlike the modern equipment and charts of the "Kon-Tiki"). "Hōkūleʻa" also remains fully operational,.

Kon-Tiki expedition. and has since completed ten other voyages, including a three-year circumnavigation of the planet from 2014 to 2017, with other sister ships.Historians today consider that the Polynesians from the west were the original inhabitants and that the story of the Hanau epe is either pure myth, or a memory of internal tribal or class conflicts. In 2011, Erik Thorsby of the University of Oslo presented DNA evidence to the Royal Society which, whilst agreeing with the west origin, also identified a distinctive but smaller genetic contribution from South America. This result was questioned in 2012 because of the possibility of.

Kon-Tiki expedition. contamination by South Americans after European contact with the islands. In 2014, further work by a team including Anna-Sapfo Malaspinas (from the Natural History Museum of Denmark) analysed the genomes of 27 native Rapa Nui people and found that their DNA was on average 76 percent Polynesian, 8 percent Native American and 16 percent European. Analysis showed that "although the European lineage could be explained by contact with white Europeans after the island was 'discovered' in 1722 by Dutch sailors, the South American component was much older, dating to between about 1280 and 1495, soon after the island was first.

Kon-Tiki expedition. colonised by Polynesians in around 1200." Genetic analysis of Polynesians and Native South Americans, published in "Nature" in July 2020, has revealed that several eastern Polynesian populations have signs of an ancient genetic signature that originated from Native South American people. An initial admixture event between Native South Americans and Polynesians, discovered by statistical analysis, took place around 1150–1230 CE.## Later recreations of "Kon-Tiki".## "Seven Little Sisters".In 1954, William Willis sailed alone on a raft "Seven Little Sisters" from Peru to American Samoa, successfully completing the journey. He sailed 6,700 (mi), which was 2,200 (mi) farther than "Kon-Tiki". In a.

Kon-Tiki expedition. second great voyage ten years later, he rafted 7457 (mi) from South America to Australia with a metal raft "Age Unlimited".## "Kantuta".In 1955, the Czech explorer and adventurer Eduard Ingris attempted to recreate the "Kon-Tiki" expedition on a balsa raft called "Kantuta". His first expedition, "Kantuta I", took place in 1955–1956 and led to failure. In 1959, Ingris built a new balsa raft, "Kantuta II", and tried to repeat the previous expedition. The second expedition was a success. Ingris was able to cross the Pacific Ocean on the balsa raft from Peru to Polynesia.## "Tahiti-Nui".A French seafarer, Éric de Bisschop,.

Kon-Tiki expedition. committed himself in a project he had had for some years: he built a Polynesian raft in order to cross the eastern Pacific Ocean from Tahiti to Chile (contrary to Thor Heyerdahl's crossing); the "Tahiti-Nui" left Papeete with a crew of five on November 8, 1956. When near the Juan Fernández Islands (Chile) in May 1957, the raft was in a very poor state and they asked for a towing, but it was damaged during the operation and had to be abandoned, but they were able to preserve all the equipment that had been aboard.## "Tahiti-Nui II".A second "Tahiti-Nui" was.

Kon-Tiki expedition. built in Constitución, Chile, leaving on April 13, 1958, towards Callao, then towards the Marquesas. It missed its target and after four months, the raft began to sink. The crew built a new smaller raft, the "Tahiti Nui III", in the ocean out of the more buoyant parts of the "Tahiti Nui II". They were swept towards Cook Islands where on August 30, the raft went aground and was wrecked at Rakahanga atoll. Éric de Bisschop died in this accident.## "Tangaroa" (1965).A Peruvian expedition led by Carlos Caravedo crossed the Pacific Ocean in 1965 in 115 days in a raft.

Kon-Tiki expedition. named "Tangaroa", of which 18 days were used by the crew to cross Tuamotus, the Tuamotu Archipielago, making "Tangaroa" the only raft that has managed to cross that dangerous archipelago of French Polynesia by its own means. On November 18, 1965, the "Tangaroa" ended its journey on the Fakarava island. Fakarava is where the "Tangaroa" is currently preserved.## Las Balsas.The 1973 Las Balsas expedition was the first (and so far only) multiple-raft crossing of the Pacific Ocean in recent history. It is the longest-known raft voyage in history. The expedition was led by Spaniard Vital Alsar, who, in 1970, led.

Kon-Tiki expedition. the La Balsa expedition, only on that occasion with one raft and three companions. The crossing was successful and, at the time, the longest raft voyage in history, until eclipsed in 1973 by Las Balsas. The purpose of the 1973 expedition was three-fold: (1) to prove that the success of 1970 was no accident, (2) to test different currents in the sea, which Alsar maintained ancient mariners knew as modern humans know road maps, and (3) to show that the original expeditions, directed perhaps toward trade or colonisation, may have consisted of small fleets of balsa rafts.## "Tangaroa" (2006).In 2006,.

Kon-Tiki expedition. the Tangaroa Expedition recreated the "Kon-Tiki" voyage using a newly built raft, the "Tangaroa", named after the Māori sea-god Tangaroa. Tangaroa's six-man crew was led by Norwegian Torgeir Higraff and included Olav Heyerdahl, grandson of Thor Heyerdahl, Bjarne Krekvik (captain), Øyvin Lauten (executive officer), Swedish Anders Berg (photographer) and Peruvian Roberto Sala. "Tangaroa" was launched on the same day that "Kon-Tiki" had been—April 28—and it reached its destination on July 7, which was 30 days faster than Heyerdahl's Kon-Tiki which had taken 101 days for the voyage. Tangaroa's speed was credited to the proper use of guaras (centerboards).## "An-Tiki".On January.

Kon-Tiki expedition. 30, 2011, "An-Tiki", a raft modeled after "Kon-Tiki", began a 3000 (mi), 70-day journey across the Atlantic Ocean from the Canary Islands to the island of Eleuthera in the Bahamas. The expedition was piloted by four men, aged from 56 to 84 years, led by Anthony Smith. The trip was designed to commemorate the journey in an open boat of survivors from the British steamship "Anglo-Saxon", sunk by the German cruiser "Widder" in 1940. The raft ended its voyage in the Caribbean island of St Maarten, completing its trip to Eleuthera in the following year with Smith and a new.

Kon-Tiki expedition. crew.## "Kon-Tiki2".On 7 November 2015, two teams with two balsa rafts "Rahiti Tane" and "Tupac Yupanqui" left Lima, Peru for Easter Island. Expedition "Kon-Tiki2" got its name because it had 2 crews from many nations: Norway, Russia, UK, Mexico, New Zealand, Sweden, and Peru. It sought to double down on Heyerdahl's voyage by sailing two rafts from South America to Polynesia and then back. Expedition leader was Torgeir Higraff from Tangaroa Expedition (2006). Øyvin Lauten and Kari Skår Dahl were captains on the first leg, while Signe Meling and Ola Borgfjord were captains on the second leg. The raft reached.

Kon-Tiki expedition. Easter Island, but did not complete the return.The two rafts were made of 11 balsa logs and 10 crossbeams held together by 2000 meters (1¼ miles) of natural fiber ropes. Tens of thousands of waves, up to six meters (20') tall, hit the rafts in an El Niño year. This stress for 16 weeks weakened the ropes, but the crew could not replace all of them. On March 3, 2016, all crew members were taken on board the Hokuetsu Ushaka freight ship after 115 days of sailing and 4½ months at sea.## Documentation.## Memoir book.A book documenting the voyage and.

Soon after the Second World War the original building was rebuilt by the mayor, Hoffmann. To promote the quick reconstruction of the theatre, the mayor himself put on piano concerts and so collected 120,000 German marks to finance the project.In December 1949 the Großes Haus (main stage) reopened with a performance of Richard Wagner's "The Mastersingers of Nuremberg". The lower levels of the building had been reconstructed quite simply and now housed the two cinemas Kamera.

The Chamber Theatre in the Wiehre was abandoned in 1958, but the Kammertheater (Chamber Theatre) opened in the main theatre with Max Frisch's "The Fire Raisers".With the first renovation in 1962, a rehearsal stage was built right under the roof. In the course of this, the decorative Art Nouveau gable, which had survived until then, was removed. In 1970, the Kamera was relocated inside the building and a further stage, the podium, added to this space. In 1973, Horst.

During the renovation and modernization between 1996 and 1998, the Kurbel ("crank") was also closed. In these rooms the Kleines Haus was subsequently installed as a performance stage. In order to do this an extension was added to the west front. In the course of reconstruction the art work by Antes had to be removed and is now, in its constituent parts, in storage. While the reconstructions were carried out, in the late 1990s, the Eschholzpark in.

Octagon. In geometry, an octagon (from the Greek ὀκτάγωνον "oktágōnon", "eight angles") is an eight-sided polygon or 8-gon.A "regular octagon" has Schläfli symbol {8} and can also be constructed as a quasiregular truncated square, t{4}, which alternates two types of edges. A truncated octagon, t{8} is a hexadecagon, {16}. A 3D analog of the octagon can be the rhombicuboctahedron with the triangular faces on it like the replaced edges, if one considers the octagon to be a truncated square.## Properties of the general octagon.The sum of all the internal angles of any octagon is 1080°. As with all polygons, the external.

Octagon. angles total 360°.If squares are constructed all internally or all externally on the sides of an octagon, then the midpoints of the segments connecting the centers of opposite squares form a quadrilateral that is both equidiagonal and orthodiagonal (that is, whose diagonals are equal in length and at right angles to each other).The midpoint octagon of a reference octagon has its eight vertices at the midpoints of the sides of the reference octagon. If squares are constructed all internally or all externally on the sides of the midpoint octagon, then the midpoints of the segments connecting the centers of opposite.

Octagon. squares themselves form the vertices of a square.## Regular octagon.A regular octagon is a closed figure with sides of the same length and internal angles of the same size. It has eight lines of reflective symmetry and rotational symmetry of order 8. A regular octagon is represented by the Schläfli symbol {8}.The internal angle at each vertex of a regular octagon is 135° (formula_1 radians). The central angle is 45° (formula_2 radians).## Area.The area of a regular octagon of side length "a" is given byformula_3In terms of the circumradius "R", the area isformula_4In terms of the apothem "r" (see also.

Octagon. inscribed figure), the area isformula_5These last two coefficients bracket the value of pi, the area of the unit circle.The area can also be expressed asformula_6where "S" is the span of the octagon, or the second-shortest diagonal; and "a" is the length of one of the sides, or bases. This is easily proven if one takes an octagon, draws a square around the outside (making sure that four of the eight sides overlap with the four sides of the square) and then takes the corner triangles (these are 45–45–90 triangles) and places them with right angles pointed inward, forming a square.

Octagon. The edges of this square are each the length of the base.Given the length of a side "a", the span "S" isformula_7The span, then, is equal to the "silver ratio" times the side, a.The area is then as above:formula_8Expressed in terms of the span, the area isformula_9Another simple formula for the area is formula_10More often the span "S" is known, and the length of the sides, "a", is to be determined, as when cutting a square piece of material into a regular octagon. From the above,formula_11The two end lengths "e" on each side (the leg lengths of the triangles (green.

Octagon. in the image) truncated from the square), as well as being formula_12 may be calculated asformula_13## Circumradius and inradius.The circumradius of the regular octagon in terms of the side length "a" isformula_14and the inradius isformula_15## Diagonals.The regular octagon, in terms of the side length "a", has three different types of diagonals:Short diagonal;Medium diagonal (also called span or height), which is twice the length of the inradius;Long diagonal, which is twice the length of the circumradius.The formula for each of them follows from the basic principles of geometry.

Twelve bars of size 4, three bars of size 5 and two bars of size 6 are required.Each side of a regular octagon subtends half a right angle at the centre of the circle which connects its vertices. Its area can thus be computed as the sum of 8 isosceles triangles, leading to the result:formula_19for an octagon of side "a".## Standard coordinates.The coordinates for the vertices of a regular octagon centered at the origin and with side length 2 are:(±1, ±(1+)) (±(1+), ±1).## Dissection.Coxeter states that every zonogon (a 2"m"-gon whose opposite sides are.

Octagon. parallel and of equal length) can be dissected into "m"("m"-1)/2 parallelograms.In particular this is true for regular polygons with evenly many sides, in which case the parallelograms are all rhombi. For the "regular octagon", "m"=4, and it can be divided into 6 rhombs, with one example shown below. This decomposition can be seen as 6 of 24 faces in a Petrie polygon projection plane of the tesseract. The list defines the number of solutions as 8, by the 8 orientations of this one dissection. These squares and rhombs are used in the Ammann–Beenker tilings.## Skew octagon.A skew octagon is a.

A "skew zig-zag octagon" has vertices alternating between two parallel planes.A regular skew octagon is vertex-transitive with equal edge lengths. In 3-dimensions it will be a zig-zag skew octagon and can be seen in the vertices and side edges of a square antiprism with the same D4d, [2+,8] symmetry, order 16.## Petrie polygons.The regular skew octagon is the Petrie polygon for these higher-dimensional regular and uniform polytopes, shown in these skew orthogonal projections of in A7,.

Elephant. tall. As with other megaherbivores, including the extinct sauropod dinosaurs, the large size of elephants likely developed to allow them to survive on vegetation with low nutritional value. Their limbs grew longer and the feet shorter and broader. The feet were originally plantigrade and developed into a digitigrade stance with cushion pads and the sesamoid bone providing support. Early proboscideans developed longer mandibles and smaller craniums while more derived ones developed shorter mandibles, which shifted the head's centre of gravity. The skull grew larger, especially the cranium, while the neck shortened to provide better support for the skull. The increase.

Elephant. in size led to the development and elongation of the mobile trunk to provide reach. The number of premolars, incisors and canines decreased.The cheek teeth (molars and premolars) of proboscideans became larger and more specialized, especially after elephants started to switch from C3-plants to C4-grasses, which caused their teeth to undergo a three-fold increase in teeth height as well as substantial multiplication of lamellae after about five million years ago. Only in the last million years or so did they return to a diet mainly consisting of C3 trees and shrubs. The upper second incisors grew into tusks, which varied.

Elephant. gait similar to running. In walking, the legs act as pendulums, with the hips and shoulders rising and falling while the foot is planted on the ground. With no "aerial phase", the fast gait does not meet all the criteria of running, although the elephant uses its legs much like other running animals, with the hips and shoulders falling and then rising while the feet are on the ground. Fast-moving elephants appear to 'run' with their front legs, but 'walk' with their hind legs and can reach a top speed of 25 (km/h). At this speed, most other quadrupeds are.

Elephant. impede dehydration and improve thermal regulation over a long period of time.## Behaviour and life history.## Ecology and activities.The African bush elephant can be found in habitats as diverse as dry savannahs, deserts, marshes, and lake shores, and in elevations from sea level to mountains above the snow line. Forest elephants mainly live in equatorial forests but will enter gallery forests and ecotones between forests and savannahs. Asian elephants prefer areas with a mix of grasses, low woody plants, and trees, primarily inhabiting dry thorn-scrub forests in southern India and Sri Lanka and evergreen forests in Malaya. Elephants are herbivorous.

Power inverter. A power inverter, inverter or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers which were originally large electromechanical devices converting AC to DC.The input voltage, output voltage and frequency, and overall power handling depend on the design of the specific device or circuitry. The inverter does not produce any power; the power is provided by the DC source.A power inverter can be entirely electronic or may be a combination of mechanical effects (such as.

Power inverter. a rotary apparatus) and electronic circuitry.Static inverters do not use moving parts in the conversion process.Power inverters are primarily used in electrical power applications where high currents and voltages are present; circuits that perform the same function for electronic signals, which usually have very low currents and voltages, are called oscillators. Circuits that perform the opposite function, converting AC to DC, are called rectifiers.## Input and output.## Input voltage.A typical power inverter device or circuit requires a stable DC power source capable of supplying enough current for the intended power demands of the system. The input voltage depends on the.

Power inverter. are two basic designs for producing household plug-in voltage from a lower-voltage DC source, the first of which uses a switching boost converter to produce a higher-voltage DC and then converts to AC. The second method converts DC to AC at battery level and uses a line-frequency transformer to create the output voltage.## Square wave.This is one of the simplest waveforms an inverter design can produce and is best suited to low-sensitivity applications such as lighting and heating. Square wave output can produce "humming" when connected to audio equipment and is generally unsuitable for sensitive electronics.## Sine wave.A power inverter.

Power inverter. device that produces a multiple step sinusoidal AC waveform is referred to as a "sine wave inverter". To more clearly distinguish the inverters with outputs of much less distortion than the "modified sine wave" (three-step) inverter designs, the manufacturers often use the phrase "pure sine wave inverter". Almost all consumer grade inverters that are sold as a "pure sine wave inverter" do not produce a smooth sine wave output at all, just a less choppy output than the square wave (two-step) and modified sine wave (three-step) inverters. However, this is not critical for most electronics as they deal with the.

Power inverter. output quite well.Where power inverter devices substitute for standard line power, a sine wave output is desirable because many electrical products are engineered to work best with a sine wave AC power source. The standard electric utility provides a sine wave, typically with minor imperfections but sometimes with significant distortion.Sine wave inverters with more than three steps in the wave output are more complex and have significantly higher cost than a modified sine wave, with only three steps, or square wave (one step) types of the same power handling. Switch-mode power supply (SMPS) devices, such as personal computers or DVD.

Power inverter. players, function on modified sine wave power. AC motors directly operated on non-sinusoidal power may produce extra heat, may have different speed-torque characteristics, or may produce more audible noise than when running on sinusoidal power.## Modified sine wave.The modified sine wave is the sum of two square waves, one of which is delayed one-quarter of the period with respect to the other. The result is a waveform which has voltage steps of zero, peak positive, zero, peak negative and again zero. This voltage value sequence is repeated continuously. The resultant voltage waveform better approximates the shape of a sinusoidal voltage.

Power inverter. entirely without problems, but if the item has a mains transformer, this can overheat depending on how marginally it is rated.However, the load may operate less efficiently owing to the harmonics associated with a modified sine wave and produce a humming noise during operation. This also affects the efficiency of the system as a whole, since the manufacturer's nominal conversion efficiency does not account for harmonics. Therefore, pure sine wave inverters may provide significantly higher efficiency than modified sine wave inverters.Most AC motors will run on MSW inverters with an efficiency reduction of about 20% owing to the harmonic content.

Power inverter. DC supply, in the manner of the MSN designs, but the switching takes place at a far faster rate, typically many KHz, so that the varying width of the pulses can be smoothed to create the sine wave. If a microprocessor is used to generate the switching timing, the harmonic content and efficiency can be closely controlled.## Output frequency.The AC output frequency of a power inverter device is usually the same as standard power line frequency, 50 or 60 hertz. The exception is in designs for motor driving, where a variable frequency results in a variable speed control.Also, if the.

Power inverter. output of the device or circuit is to be further conditioned (for example stepped up) then the frequency may be much higher for good transformer efficiency.## Output voltage.The AC output voltage of a power inverter is often regulated to be the same as the grid line voltage, typically 120 or 240 VAC at the distribution level, even when there are changes in the load that the inverter is driving. This allows the inverter to power numerous devices designed for standard line power.Some inverters also allow selectable or continuously variable output voltages.## Output power.A power inverter will often have an overall.

Power inverter. battery from the others.## Applications.## DC power source usage.An inverter converts the DC electricity from sources such as batteries or fuel cells to AC electricity. The electricity can be at any required voltage; in particular it can operate AC equipment designed for mains operation, or rectified to produce DC at any desired voltage.## Uninterruptible power supplies.An uninterruptible power supply (UPS) uses batteries and an inverter to supply AC power when mains power is not available. When mains power is restored, a rectifier supplies DC power to recharge the batteries.## Electric motor speed control.Inverter circuits designed to produce a variable output.

Power inverter. voltage range are often used within motor speed controllers.The DC power for the inverter section can be derived from a normal AC wall outlet or some other source. Control and feedback circuitry is used to adjust the final output of the inverter section which will ultimately determine the speed of the motor operating under its mechanical load. Motor speed control needs are numerous and include things like: industrial motor driven equipment, electric vehicles, rail transport systems, and power tools.Switching states are developed for positive, negative and zero voltages as per the patterns given in the switching Table 1. The generated.

Power inverter. gate pulses are given to each switch in accordance with the developed pattern and thus the output is obtained.## In refrigeration compressors.An inverter can be used to control the speed of the compressor motor to drive variable refrigerant flow in a refrigeration or air conditioning system to regulate system performance. Such installations are known as inverter compressors. Traditional methods of refrigeration regulation use single-speed compressors switched on and off periodically; inverter-equipped systems have a variable-frequency drive that control the speed of the motor and thus the compressor and cooling output. The variable-frequency AC from the inverter drives a brushless or.

Power inverter. induction motor, the speed of which is proportional to the frequency of the AC it is fed, so the compressor can be run at variable speeds—eliminating compressor stop-start cycles increases efficiency. A microcontroller typically monitors the temperature in the space to be cooled, and adjusts the speed of the compressor to maintain the desired temperature. The additional electronics and system hardware add cost to the equipment, but can result in substantial savings in operating costs. The first inverter air conditioners were released by Toshiba in 1981, in Japan.## Power grid.Grid-tied inverters are designed to feed into the electric power distribution.

Power inverter. hundred megawatts, are used to deliver power from high voltage direct current transmission systems to alternating current distribution systems.## Solar.A solar inverter is a balance of system (BOS) component of a photovoltaic system and can be used for both grid-connected and off-grid systems. Solar inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection.Solar micro-inverters differ from conventional inverters, as an individual micro-inverter is attached to each solar panel. This can improve the overall efficiency of the system. The output from several micro-inverters is then combined and often fed to the electrical.

Power inverter. grid.In other applications, a conventional inverter can be combined with a battery bank maintained by a solar charge controller. This combination of components is often referred to as a solar generator.Solar inverters are also used in spacecraft photovoltaic system.## Induction heating.Inverters convert low frequency main AC power to higher frequency for use in induction heating. To do this, AC power is first rectified to provide DC power. The inverter then changes the DC power to high frequency AC power. Due to the reduction in the number of DC sources employed, the structure becomes more reliable and the output voltage has.

Power inverter. higher resolution due to an increase in the number of steps so that the reference sinusoidal voltage can be better achieved. This configuration has recently become very popular in AC power supply and adjustable speed drive applications. This new inverter can avoid extra clamping diodes or voltage balancing capacitors.There are three kinds of level shifted modulation techniques, namely: Phase Opposition Disposition (POD) Alternative Phase Opposition Disposition (APOD) Phase Disposition (PD)## HVDC power transmission.With HVDC power transmission, AC power is rectified and high voltage DC power is transmitted to another location. At the receiving location, an inverter in a static inverter.

Power inverter. plant converts the power back to AC. The inverter must be synchronized with grid frequency and phase and minimize harmonic generation.## Electroshock weapons.Electroshock weapons and tasers have a DC/AC inverter to generate several tens of thousands of V AC out of a small 9 V DC battery. First the 9 V DC is converted to 400–2000 V AC with a compact high frequency transformer, which is then rectified and temporarily stored in a high voltage capacitor until a pre-set threshold voltage is reached. When the threshold (set by way of an airgap or TRIAC) is reached, the capacitor dumps its.

Power inverter. entire load into a pulse transformer which then steps it up to its final output voltage of 20–60 kV. A variant of the principle is also used in electronic flash and bug zappers, though they rely on a capacitor-based voltage multiplier to achieve their high voltage.## Miscellaneous.Typical applications for power inverters include: Portable consumer devices that allow the user to connect a battery, or set of batteries, to the device to produce AC power to run various electrical items such as lights, televisions, kitchen appliances, and power tools. Use in power generation systems such as electric utility companies or solar.

Power inverter. generating systems to convert DC power to AC power. Use within any larger electronic system where an engineering need exists for deriving an AC source from a DC source. Frequency conversion - if a user in (say) a 50 Hz country needs a 60 Hz supply to power equipment that is frequency-specific, such as a small motor or some electronics, it is possible to convert the frequency by running an inverter with a 60 Hz output from a DC source such as a 12V power supply running from the 50 Hz mains.## Circuit description.## Basic design.In one simple inverter circuit,.

Power inverter. DC power is connected to a transformer through the center tap of the primary winding. A relay switch is rapidly switched back and forth to allow current to flow back to the DC source following two alternate paths through one end of the primary winding and then the other. The alternation of the direction of current in the primary winding of the transformer produces alternating current (AC) in the secondary circuit.The electromechanical version of the switching device includes two stationary contacts and a spring supported moving contact. The spring holds the movable contact against one of the stationary contacts and.

Power inverter. provide large power handling capability in a semiconductor device, and can readily be controlled over a variable firing range.The switch in the simple inverter described above, when not coupled to an output transformer, produces a square voltage waveform due to its simple off and on nature as opposed to the sinusoidal waveform that is the usual waveform of an AC power supply. Using Fourier analysis, periodic waveforms are represented as the sum of an infinite series of sine waves. The sine wave that has the same frequency as the original waveform is called the fundamental component. The other sine waves,.

Power inverter. car that is moving can turn into a source of energy and can, with the right inverter topology (full H-bridge) charge the car battery when decelerating or braking. In a similar manner, the right topology (full H-bridge) can invert the roles of "source" and "load", that is, if for example the voltage is higher on the AC "load" side (by adding a solar inverter, similar to a gen-set, but solid state), energy can flow back into the DC "source" or battery.Based on the basic H-bridge topology, there are two different fundamental control strategies called basic frequency-variable bridge converter and PWM.

Power inverter. control. Here, in the left image of H-bridge circuit, the top left switch is named as "S1", and others are named as "S2, S3, S4" in counterclockwise order.For the basic frequency-variable bridge converter, the switches can be operated at the same frequency as the AC in the electric grid. However, it is the rate at which the switches open and close that determines the AC frequency. When S1 and S4 are on and the other two are off, the load is provided with positive voltage and vice versa. We could control the on-off states of the switches to adjust the.

Power inverter. AC magnitude and phase. We could also control the switches to eliminate certain harmonics. This includes controlling the switches to create notches, or 0-state regions, in the output waveform or adding the outputs of two or more converters in parallel that are phase shifted in respect to one another.Another method that can be used is PWM. Unlike the basic frequency-variable bridge converter, in the PWM controlling strategy, only two switches S3, S4 can operate at the frequency of the AC side or at any low frequency. The other two would switch much faster (typically 100 KHz) to create square voltages.

Power inverter. level of distortion caused by harmonics. The waveform quality of AC produced directly by H-bridge mentioned above would be not as good as we want.The issue of waveform quality can be addressed in many ways. Capacitors and inductors can be used to filter the waveform. If the design includes a transformer, filtering can be applied to the primary or the secondary side of the transformer or to both sides. Low-pass filters are applied to allow the fundamental component of the waveform to pass to the output while limiting the passage of the harmonic components. If the inverter is designed to.

Power inverter. provide power at a fixed frequency, a resonant filter can be used. For an adjustable frequency inverter, the filter must be tuned to a frequency that is above the maximum fundamental frequency.Since most loads contain inductance, feedback rectifiers or antiparallel diodes are often connected across each semiconductor switch to provide a path for the peak inductive load current when the switch is turned off. The antiparallel diodes are somewhat similar to the "freewheeling diodes" used in AC/DC converter circuits.Fourier analysis reveals that a waveform, like a square wave, that is anti-symmetrical about the 180 degree point contains only odd harmonics,.

Power inverter. simplifies the electronics, but the inductors and capacitors tend to be large and heavy. Its high efficiency makes this approach popular in large uninterruptible power supplies in data centers that run the inverter continuously in an "online" mode to avoid any switchover transient when power is lost.A closely related approach uses a ferroresonant transformer, also known as a constant voltage transformer, to remove harmonics and to store enough energy to sustain the load for a few AC cycles. This property makes them useful in standby power supplies to eliminate the switchover transient that otherwise occurs during a power failure while.

Power inverter. size and volume. In 2014, Google together with IEEE started an open competition named Little Box Challenge, with a prize money of $1,000,000, to build a (much) smaller power inverter.## History.## Early inverters.From the late nineteenth century through the middle of the twentieth century, DC-to-AC power conversion was accomplished using rotary converters or motor-generator sets (M-G sets). In the early twentieth century, vacuum tubes and gas-filled tubes began to be used as switches in inverter circuits. The most widely used type of tube was the thyratron.The origins of electromechanical inverters explain the source of the term "inverter". Early AC-to-DC converters.

Power inverter. used an induction or synchronous AC motor direct-connected to a generator (dynamo) so that the generator's commutator reversed its connections at exactly the right moments to produce DC. A later development is the synchronous converter, in which the motor and generator windings are combined into one armature, with slip rings at one end and a commutator at the other and only one field frame. The result with either is AC-in, DC-out. With an M-G set, the DC can be considered to be separately generated from the AC; with a synchronous converter, in a certain sense it can be considered to.

Power inverter. be "mechanically rectified AC". Given the right auxiliary and control equipment, an M-G set or rotary converter can be "run backwards", converting DC to AC. Hence an inverter is an inverted converter.## Controlled rectifier inverters.Since early transistors were not available with sufficient voltage and current ratings for most inverter applications, it was the 1957 introduction of the thyristor or silicon-controlled rectifier (SCR) that initiated the transition to solid state inverter circuits.The "commutation" requirements of SCRs are a key consideration in SCR circuit designs. SCRs do not turn off or "commutate" automatically when the gate control signal is shut off. They.

Power inverter. only turn off when the forward current is reduced to below the minimum holding current, which varies with each kind of SCR, through some external process. For SCRs connected to an AC power source, commutation occurs naturally every time the polarity of the source voltage reverses. SCRs connected to a DC power source usually require a means of forced commutation that forces the current to zero when commutation is required. The least complicated SCR circuits employ natural commutation rather than forced commutation. With the addition of forced commutation circuits, SCRs have been used in the types of inverter circuits described.

Power inverter. above.In applications where inverters transfer power from a DC power source to an AC power source, it is possible to use AC-to-DC controlled rectifier circuits operating in the inversion mode. In the inversion mode, a controlled rectifier circuit operates as a line commutated inverter. This type of operation can be used in HVDC power transmission systems and in regenerative braking operation of motor control systems.Another type of SCR inverter circuit is the current source input (CSI) inverter. A CSI inverter is the dual of a six-step voltage source inverter. With a current source inverter, the DC power supply is configured.

Power inverter. as a current source rather than a voltage source. The inverter SCRs are switched in a six-step sequence to direct the current to a three-phase AC load as a stepped current waveform. CSI inverter commutation methods include load commutation and parallel capacitor commutation. With both methods, the input current regulation assists the commutation. With load commutation, the load is a synchronous motor operated at a leading power factor.As they have become available in higher voltage and current ratings, semiconductors such as transistors or IGBTs that can be turned off by means of control signals have become the preferred switching components.

Power inverter. for use in inverter circuits.## Rectifier and inverter pulse numbers.Rectifier circuits are often classified by the number of current pulses that flow to the DC side of the rectifier per cycle of AC input voltage. A single-phase half-wave rectifier is a one-pulse circuit and a single-phase full-wave rectifier is a two-pulse circuit. A three-phase half-wave rectifier is a three-pulse circuit and a three-phase full-wave rectifier is a six-pulse circuit.With three-phase rectifiers, two or more rectifiers are sometimes connected in series or parallel to obtain higher voltage or current ratings. The rectifier inputs are supplied from special transformers that provide phase.

Power inverter. shifted outputs. This has the effect of phase multiplication. Six phases are obtained from two transformers, twelve phases from three transformers and so on. The associated rectifier circuits are 12-pulse rectifiers, 18-pulse rectifiers and so on...When controlled rectifier circuits are operated in the inversion mode, they would be classified by pulse number also. Rectifier circuits that have a higher pulse number have reduced harmonic content in the AC input current and reduced ripple in the DC output voltage. In the inversion mode, circuits that have a higher pulse number have lower harmonic content in the AC output voltage waveform.## Other.

The total of the internal angles of any simple (non-self-intersecting) hexagon is 720°.## Regular hexagon.A "regular hexagon" has Schläfli symbol {6} and can also be constructed as a truncated equilateral triangle, t{3}, which alternates two types of edges.A regular hexagon is defined as a hexagon that is both equilateral and equiangular. It is bicentric, meaning that it is both cyclic (has a circumscribed circle) and tangential (has an inscribed circle).The common length of the sides equals the radius.

Hexagon. of the circumscribed circle or circumcircle, which equals formula_1 times the apothem (radius of the inscribed circle). All internal angles are 120 degrees. A regular hexagon has six rotational symmetries ("rotational symmetry of order six") and six reflection symmetries ("six lines of symmetry"), making up the dihedral group D6. The longest diagonals of a regular hexagon, connecting diametrically opposite vertices, are twice the length of one side. From this it can be seen that a triangle with a vertex at the center of the regular hexagon and sharing one side with the hexagon is equilateral, and that the regular hexagon.

Hexagon. can be partitioned into six equilateral triangles.Like squares and equilateral triangles, regular hexagons fit together without any gaps to "tile the plane" (three hexagons meeting at every vertex), and so are useful for constructing tessellations. The cells of a beehive honeycomb are hexagonal for this reason and because the shape makes efficient use of space and building materials. The Voronoi diagram of a regular triangular lattice is the honeycomb tessellation of hexagons. It is not usually considered a triambus, although it is equilateral.## Parameters.The maximal diameter (which corresponds to the long diagonal of the hexagon), "D", is twice the maximal.

Hexagon. radius or circumradius, "R", which equals the side length, "t". The minimal diameter or the diameter of the inscribed circle (separation of parallel sides, flat-to-flat distance, short diagonal or height when resting on a flat base), "d", is twice the minimal radius or inradius, "r". The maxima and minima are related by the same factor:formula_2 and, similarly, formula_3The area of a regular hexagonformula_4For any regular polygon, the area can also be expressed in terms of the apothem "a" and the perimeter "p". For the regular hexagon these are given by "a" = "r", and "p"formula_5, soformula_6The regular hexagon fills the.

Hexagon. fraction formula_7 of its circumscribed circle.If a regular hexagon has successive vertices A, B, C, D, E, F and if P is any point on the circumcircle between B and C, then .It follows from the ratio of circumradius to inradius that the height-to-width ratio of a regular hexagon is 1:1.1547005; that is, a hexagon with a long diagonal of 1.0000000 will have a distance of 0.8660254 between parallel sides.## Point in plane.For an arbitrary point in the plane of a regular hexagon with circumradius formula_8, whose distances to the centroid of the regular hexagon and its six vertices are.

Hexagon. formula_9 and formula_10 respectively, we haveformula_11formula_12formula_13If formula_10 are the distances from the vertices of a regular hexagon to any point on its circumcircle, then formula_15## Symmetry.The "regular hexagon" has D6 symmetry. There are 16 subgroups. There are 8 up to isomorphism: itself (D6), 2 dihedral: (D3, D2), 4 cyclic: (Z6, Z3, Z2, Z1) and the trivial (e)These symmetries express nine distinct symmetries of a regular hexagon. John Conway labels these by a letter and group order. r12 is full symmetry, and a1 is no symmetry. p6, an isogonal hexagon constructed by three mirrors can alternate long and short edges, and.

Hexagon. d6, an isotoxal hexagon constructed with equal edge lengths, but vertices alternating two different internal angles. These two forms are duals of each other and have half the symmetry order of the regular hexagon. The i4 forms are regular hexagons flattened or stretched along one symmetry direction. It can be seen as an elongated rhombus, while d2 and p2 can be seen as horizontally and vertically elongated kites. g2 hexagons, with opposite sides parallel are also called hexagonal parallelogons.Each subgroup symmetry allows one or more degrees of freedom for irregular forms. Only the g6 subgroup has no degrees of freedom.

Hexagon. but can seen as directed edges.Hexagons of symmetry g2, i4, and r12, as parallelogons can tessellate the Euclidean plane by translation. Other hexagon shapes can tile the plane with different orientations.## A2 and G2 groups.The 6 roots of the simple Lie group , represented by a Dynkin diagram , are in a regular hexagonal pattern. The two simple roots have a 120° angle between them.The 12 roots of the Exceptional Lie group G2, represented by a Dynkin diagram are also in a hexagonal pattern. The two simple roots of two lengths have a 150° angle between them.## Dissection.Coxeter states that.

Hexagon. every zonogon (a 2"m"-gon whose opposite sides are parallel and of equal length) can be dissected into parallelograms. In particular this is true for regular polygons with evenly many sides, in which case the parallelograms are all rhombi. This decomposition of a regular hexagon is based on a Petrie polygon projection of a cube, with 3 of 6 square faces. Other parallelogons and projective directions of the cube are dissected within rectangular cuboids.## Related polygons and tilings.A regular hexagon has Schläfli symbol {6}. A regular hexagon is a part of the regular hexagonal tiling, {6,3}, with three hexagonal faces around.

Hexagon. each vertex.A regular hexagon can also be created as a truncated equilateral triangle, with Schläfli symbol t{3}. Seen with two types (colors) of edges, this form only has D3 symmetry.A truncated hexagon, t{6}, is a dodecagon, {12}, alternating two types (colors) of edges. An alternated hexagon, h{6}, is an equilateral triangle, {3}. A regular hexagon can be stellated with equilateral triangles on its edges, creating a hexagram. A regular hexagon can be dissected into six equilateral triangles by adding a center point. This pattern repeats within the regular triangular tiling.A regular hexagon can be extended into a regular dodecagon by.

Hexagon. adding alternating squares and equilateral triangles around it. This pattern repeats within the rhombitrihexagonal tiling.## Self-crossing hexagons.There are six self-crossing hexagons with the vertex arrangement of the regular hexagon:## Hexagonal structures.From bees' honeycombs to the Giant's Causeway, hexagonal patterns are prevalent in nature due to their efficiency. In a hexagonal grid each line is as short as it can possibly be if a large area is to be filled with the fewest hexagons. This means that honeycombs require less wax to construct and gain much strength under compression.Irregular hexagons with parallel opposite edges are called parallelogons and can also tile.

Hexagon. the plane by translation. In three dimensions, hexagonal prisms with parallel opposite faces are called parallelohedrons and these can tessellate 3-space by translation.## Tesselations by hexagons.In addition to the regular hexagon, which determines a unique tessellation of the plane, any irregular hexagon which satisfies the Conway criterion will tile the plane.## Hexagon inscribed in a conic section.Pascal's theorem (also known as the "Hexagrammum Mysticum Theorem") states that if an arbitrary hexagon is inscribed in any conic section, and pairs of opposite sides are extended until they meet, the three intersection points will lie on a straight line, the "Pascal line.

Hexagon. of that configuration.## Cyclic hexagon.The Lemoine hexagon is a cyclic hexagon (one inscribed in a circle) with vertices given by the six intersections of the edges of a triangle and the three lines that are parallel to the edges that pass through its symmedian point.If the successive sides of a cyclic hexagon are "a", "b", "c", "d", "e", "f", then the three main diagonals intersect in a single point if and only if .If, for each side of a cyclic hexagon, the adjacent sides are extended to their intersection, forming a triangle exterior to the given side, then the segments.

Hexagon. connecting the circumcenters of opposite triangles are concurrent.If a hexagon has vertices on the circumcircle of an acute triangle at the six points (including three triangle vertices) where the extended altitudes of the triangle meet the circumcircle, then the area of the hexagon is twice the area of the triangle.## Hexagon tangential to a conic section.Let ABCDEF be a hexagon formed by six tangent lines of a conic section. Then Brianchon's theorem states that the three main diagonals AD, BE, and CF intersect at a single point.In a hexagon that is tangential to a circle and that has consecutive sides.

Hexagon. "a", "b", "c", "d", "e", and "f",formula_16## Equilateral triangles on the sides of an arbitrary hexagon.If an equilateral triangle is constructed externally on each side of any hexagon, then the midpoints of the segments connecting the centroids of opposite triangles form another equilateral triangle.## Skew hexagon.A skew hexagon is a skew polygon with six vertices and edges but not existing on the same plane. The interior of such an hexagon is not generally defined. A "skew zig-zag hexagon" has vertices alternating between two parallel planes.A regular skew hexagon is vertex-transitive with equal edge lengths. In three dimensions it will be.

Hexagon. a zig-zag skew hexagon and can be seen in the vertices and side edges of a triangular antiprism with the same D3d, [2+,6] symmetry, order 12.The cube and octahedron (same as triangular antiprism) have regular skew hexagons as petrie polygons.## Petrie polygons.The regular skew hexagon is the Petrie polygon for these higher dimensional regular, uniform and dual polyhedra and polytopes, shown in these skew orthogonal projections:## Convex equilateral hexagon.A "principal diagonal" of a hexagon is a diagonal which divides the hexagon into quadrilaterals. In any convex equilateral hexagon (one with all sides equal) with common side "a", there exists a.

The Archimedean solids with some hexagonal faces are the truncated tetrahedron, truncated octahedron, truncated icosahedron (of soccer ball and fullerene fame), truncated cuboctahedron and the truncated icosidodecahedron. These hexagons can be considered truncated triangles, with Coxeter diagrams of the form and .There are other symmetry polyhedra with stretched or flattened hexagons, like these Goldberg polyhedron G(2,0):There are also 9 Johnson solids with regular hexagons: 24-cell: a.

Airplane. An airplane or aeroplane (informally plane) is a fixed-wing aircraft that is propelled forward by thrust from a jet engine, propeller, or rocket engine. Airplanes come in a variety of sizes, shapes, and wing configurations. The broad spectrum of uses for airplanes includes recreation, transportation of goods and people, military, and research. Worldwide, commercial aviation transports more than four billion passengers annually on airliners and transports more than 200 billion tonne-kilometers of cargo annually, which is less than 1% of the world's cargo movement. Most airplanes are flown by a pilot on board the aircraft, but some are designed to.

Airplane. and either Latin "planus", "level", or Greek πλάνος ("planos"), "wandering". "Aéroplane" originally referred just to the wing, as it is a plane moving through the air. In an example of synecdoche, the word for the wing came to refer to the entire aircraft.In the United States and Canada, the term "airplane" is used for powered fixed-wing aircraft. In the United Kingdom and Ireland and most of the Commonwealth, the term "aeroplane" () is usually applied to these aircraft.## History.## Antecedents.Many stories from antiquity involve flight, such as the Greek legend of Icarus and Daedalus, and the Vimana in ancient Indian.

Airplane. of Birds" (1502), noting for the first time the distinction between the center of mass and the center of pressure of flying birds.In 1799, George Cayley set forth the concept of the modern airplane as a fixed-wing flying machine with separate systems for lift, propulsion, and control. Cayley was building and flying models of fixed-wing aircraft as early as 1803, and he built a successful passenger-carrying glider in 1853. In 1856, Frenchman Jean-Marie Le Bris made the first powered flight, by having his glider "L'Albatros artificiel" pulled by a horse on a beach. Then the Russian Alexander F. Mozhaisky also.

Airplane. subsequently abandoned work on it.In the 1890s, Lawrence Hargrave conducted research on wing structures and developed a box kite that lifted the weight of a man. His box kite designs were widely adopted. Although he also developed a type of rotary aircraft engine, he did not create and fly a powered fixed-wing aircraft.Between 1867 and 1896, the German pioneer of human aviation Otto Lilienthal developed heavier-than-air flight. He was the first person to make well-documented, repeated, successful gliding flights. Lilienthal's work led to him developing the concept of the modern wing, his flight attempts in 1891 are seen as the.

Airplane. rigorously inspected to search for imperfections and defects. After approval by inspectors, the plane is put through a series of flight tests to assure that all systems are working correctly and that the plane handles properly. Upon passing these tests, the plane is ready to receive the "final touchups" (internal configuration, painting, etc.), and is then ready for the customer.## Characteristics.## Airframe.The structural parts of a fixed-wing aircraft are called the airframe. The parts present can vary according to the aircraft's type and purpose. Early types were usually made of wood with fabric wing surfaces, When engines became available for.

Airplane. to stabilize the plane's pitch (tilt up or down) and mounts the elevators, which provide pitch control. "Landing gear", a set of wheels, skids, or floats that support the plane while it is on the surface. On seaplanes, the bottom of the fuselage or floats (pontoons) support it while on the water. On some planes the landing gear retracts during flight to reduce drag.## Wings.The wings of a fixed-wing aircraft are static planes extending either side of the aircraft. When the aircraft travels forwards, air flows over the wings, which are shaped to create lift. This shape is called an.

Airplane. airfoil and is shaped like a bird's wing.## Wing structure.Airplanes have flexible wing surfaces which are stretched across a frame and made rigid by the lift forces exerted by the airflow over them. Larger aircraft have rigid wing surfaces which provide additional strength.Whether flexible or rigid, most wings have a strong frame to give them their shape and to transfer lift from the wing surface to the rest of the aircraft. The main structural elements are one or more spars running from root to tip, and many ribs running from the leading (front) to the trailing (rear) edge.Early airplane engines.

Airplane. control, most fixed-wing types have an empennage comprising a fin and rudder which act horizontally and a tailplane and elevator which act vertically. These control surfaces can typically be trimmed to relieve control forces for various stages of flight. This is so common that it is known as the conventional layout. Sometimes there may be two or more fins, spaced out along the tailplane.Some types have a horizontal "canard" foreplane ahead of the main wing, instead of behind it. This foreplane may contribute to the lift, the trim, or control of the aircraft, or to several of these.## Controls and.

Scilla. Scilla () is a genus of about 30 to 80 species of bulb-forming perennial herbaceous plants in the family Asparagaceae, subfamily Scilloideae. Sometimes called the squills in English, they are native to woodlands, subalpine meadows, and seashores throughout Europe, Africa and the Middle East. A few species are also naturalized in Australasia and North America. Their flowers are usually blue, but white, pink, and purple types are known; most flower in early spring, but a few are autumn-flowering. Several "Scilla" species are valued as ornamental garden plants.## Taxonomy.Species of "Scilla" have been known since classical antiquity, being described by both.

Scilla. particularly with the adoption of the Angiosperm Phylogeny Group system. Significantly, hyacinth-like plants including "Scilla" were initially placed in a separate family, the Hyacinthaceae in the order Asparagales, specifically in the very large subfamily Hyacinthoideae. Since 2009, the Hyacintheae, including "Scilla", have been considered as Scilloideae, a subfamily of the family Asparagaceae. There they are placed as one of about 21 genera in the subtribe Hyacinthinae within tribe Hyacintheae. The most closely related genera to "Scilla" were "Muscari" and "Chionodoxa" .## Subdivision.For some time, "Chionodoxa" had been considered a possible synonym to "Scilla bifolia" and molecular methods failed to support.

Scilla. the existence of a separate genus, but rather its specimens appeared intermixed with those of "Scilla". Although there are distinguishing morphological features (e.g fused tepal bases and broadened filaments), these were considered paraphyletic, having arisen in several lines within the Hyacinthaceae. Furthermore, it was observed that "Chionodoxa" was capable of hybridization with "Scilla bifolia". It was therefore proposed that "Chionodoxa" be considered an obsolete genus and be submerged within "Scilla". Subsequently it was proposed that the species of Scilla be split into two sections, Chionodoxa that would include those taxa previously considered to belong in the genus "Chionodoxa", and "Scilla.
