Nationals Park is a baseball stadium along the Anacostia River in the Navy Yard neighborhood of Washington, D.C. Home to Major League Baseball's Washington Nationals since its completion in 2008, it was the first LEED-certified green major professional sports stadium in the United States.Designed by HOK Sport and Devrouax & Purnell Architects and Planners, the ballpark cost $693 million to build. An additional $84.2 million was spent on transportation, art, and infrastructure upgrades, bringing the total cost to $783.9 million. The stadium has a capacity of 41,339. The Washington Monument and the Capitol building are visible from the upper decks on the first base side of the field.Nationals Park hosted the 2018 Major League Baseball All-Star Game, the first All-Star Game to be played in Washington, D.C. since 1969. It hosted games 3, 4, and 5 of the World Series, the first in the city since .


Trafalgar Square ( ) is a public square in the City of Westminster, Central London, laid out in the early 19th century around the area formerly known as Charing Cross. At its centre is a high column bearing a statue of Admiral Nelson commemorating the victory at the Battle of Trafalgar. The battle took place on 21 October 1805 off the coast of Cape Trafalgar; the British navy established dominance at sea in the Napoleonic Wars over the fleets of France and Spain.The site around Trafalgar Square had been a significant landmark since the 1200s. For centuries, distances measured from Charing Cross have served as location markers. The site of the present square formerly contained the elaborately designed, enclosed courtyard, King's Mews. After George IV moved the mews to Buckingham Palace, the area was redeveloped by John Nash, but progress was slow after his death, and the square did not open until 1844. The 169 (ft) Nelson's Column at its centre is guarded by four lion statues. A number of commemorative statues and sculptures occupy the square, but the Fourth Plinth, left empty since 1840, has been host to contemporary art since 1999. Prominent buildings facing the square include the National Gallery, St Martin-in-the-Fields, Canada House, and South Africa House.The square has been used for community gatherings and political demonstrations, including Bloody Sunday in 1887, the culmination of the first Aldermaston March, anti-war protests, and campaigns against climate change. A Christmas tree has been donated to the square by Norway since 1947 and is erected for twelve days before and after Christmas Day. The square is a centre of annual celebrations on New Year's Eve. It was well known for its feral pigeons until their removal in the early 21st century.


Denali (; also known as Mount McKinley, its former official name) is the highest mountain peak in North America, with a summit elevation of 20310 (ft) above sea level. With a topographic prominence of 20194 (ft) and a topographic isolation of 4621.1 (mi), Denali is the third most prominent and third most isolated peak on Earth, after Mount Everest and Aconcagua. Located in the Alaska Range in the interior of the U.S. state of Alaska, Denali is the centerpiece of Denali National Park and Preserve.The Koyukon people who inhabit the area around the mountain have referred to the peak as "Denali" for centuries. In 1896, a gold prospector named it "Mount McKinley" in support of then-presidential candidate William McKinley; that name was the official name recognized by the federal government of the United States from 1917 until 2015. In August 2015, 40 years after Alaska had done so, the United States Department of the Interior announced the change of the official name of the mountain to Denali.In 1903, James Wickersham recorded the first attempt at climbing Denali, which was unsuccessful. In 1906, Frederick Cook claimed the first ascent, but this ascent is unverified and its legitimacy questioned. The first verifiable ascent to Denali's summit was achieved on June 7, 1913, by climbers Hudson Stuck, Harry Karstens, Walter Harper, and Robert Tatum, who went by the South Summit. In 1951, Bradford Washburn pioneered the West Buttress route, considered to be the safest and easiest route, and therefore the most popular currently in use.On September 2, 2015, the U.S. Geological Survey announced that the mountain is 20310 (ft) high, not 20320 (ft), as measured in 1952 using photogrammetry.


The poinsettia ( or ) ("Euphorbia pulcherrima") is a commercially important plant species of the diverse spurge family (Euphorbiaceae). Indigenous to Mexico and Central America, the poinsettia was first described by Europeans in 1834. It is particularly well known for its red and green foliage and is widely used in Christmas floral displays. It derives its common English name from Joel Roberts Poinsett, the first United States Minister to Mexico, who is credited with introducing the plant to the US in the 1820s. Poinsettias are shrubs or small trees, with heights of 0.6-4 (m). Though often stated to be highly toxic, the poinsettia is not dangerous to pets or children. Exposure to the plant, even consumption, most often results in no effect, though it can cause nausea, vomiting, or diarrhea.Wild poinsettias occur from Mexico to southern Guatemala, growing on mid-elevation, Pacific-facing slopes. One population in the Mexican state of Guerrero is much further inland, however, and is thought to be the ancestor of most cultivated populations. Wild poinsettia populations are highly fragmented, as their habitat is experiencing largely unregulated deforestation. They were cultivated by the Aztecs for use in traditional medicine. They became associated with the Christmas holiday and are popular seasonal decorations. Every year in the US, approximately 70 million poinsettias of many cultivated varieties are sold in a six-week period. Many of these poinsettias are grown by Paul Ecke Ranch, which serves half the worldwide market and 70% of the US market.


Eggs Benedict is a common American breakfast or brunch dish, consisting of two halves of an English muffin, each topped with Canadian bacon, a poached egg, and hollandaise sauce. It was popularized in New York City.


Fried rice is a dish of cooked rice that has been stir-fried in a wok or a frying pan and is usually mixed with other ingredients such as eggs, vegetables, seafood, or meat. It is often eaten by itself or as an accompaniment to another dish. Fried rice is a popular component of East Asian, Southeast Asian and certain South Asian cuisines, as well as a staple national dish of Indonesia. As a homemade dish, fried rice is typically made with ingredients left over from other dishes, leading to countless variations. Fried rice first developed during the Sui Dynasty in China and as such all fried rice dishes can trace their origins to Chinese fried rice.Many varieties of fried rice have their own specific list of ingredients. In Greater China, common varieties include Yangzhou fried rice and Hokkien fried rice. Japanese chāhan is considered a Japanese Chinese dish, having derived from Chinese fried rice dishes. Korean bokkeum-bap in general is not of Korean Chinese origin, although there is a Korean Chinese variety of "bokkeum-bap". In Southeast Asia, similarly constructed Indonesian, Malaysian, and Singaporean "nasi goreng" and Thai "khao phat" are popular dishes. In the West, most restaurants catering to vegetarians have invented their own varieties of fried rice, including egg fried rice. Fried rice is also seen on the menus of American restaurants offering cuisines with no native tradition of the dish. Additionally, the cuisine of some Latin American countries includes variations on fried rice, including Ecuadorian chaulafan, Peruvian arroz chaufa, Cuban arroz frito, and Puerto Rican arroz mamposteao.Fried rice is a common street food in Asia. In some Asian countries, small restaurants, street vendors and traveling hawkers specialize in serving fried rice. In Indonesian cities it is common to find fried rice street hawkers moving through the streets with their food cart and stationing it in busy streets or residential areas. Many Southeast Asian street food stands offer fried rice with a selection of optional garnishes and side dishes.


Ruins () are the remains of a civilization's architecture. The term refers to formerly intact structures that have fallen into a state of partial or total disrepair over time due to a variety of factors, such as lack of maintenance, deliberate destruction by humans, or uncontrollable destruction by natural phenomena. The most common root causes that yield ruins in their wake are natural disasters, armed conflict, and population decline, with many structures becoming progressively derelict over time due to long-term weathering and scavenging.There are famous ruins all over the world, with notable sites originating from ancient China, the Indus Valley and other regions of ancient India, ancient Iran, ancient Israel and Judea, ancient Iraq, ancient Greece, ancient Egypt, Roman sites throughout the Mediterranean Basin, and Incan and Mayan sites in the Americas. Ruins are of great importance to historians, archaeologists and anthropologists, whether they were once individual fortifications, places of worship, ancient universities, houses and utility buildings, or entire villages, towns, and cities. Many ruins have become UNESCO World Heritage Sites in recent years, to identify and preserve them as areas of outstanding value to humanity.


A fire station (also called a fire house, fire hall, firemen's hall, or engine house) is a structure or other area for storing firefighting apparatuses such as fire engines and related vehicles, personal protective equipment, fire hoses and other specialized equipment. Fire stations frequently contain working and living space for the firefighters and support staff.In large US cities, fire stations are often named for the primary fire companies and apparatus housed there, such as "Ladder 49". Other fire stations are named based on the district, neighborhood, town or village where they are located, or given a number.


A control room or operations room is a central space where a large physical facility or physically dispersed service can be monitored and controlled. It is often part of a larger command center.


A convention center (American English; or conference centre in British English) is a large building that is designed to hold a convention, where individuals and groups gather to promote and share common interests. Convention centers typically offer sufficient floor area to accommodate several thousand attendees. Very large venues, suitable for major trade shows, are sometimes known as exhibition halls. Convention centers typically have at least one auditorium and may also contain concert halls, lecture halls, meeting rooms, and conference rooms. Some large resort area hotels include a convention center.


Golf is a club-and-ball sport in which players use various clubs to hit balls into a series of holes on a course in as few strokes as possible.Golf, unlike most ball games, cannot and does not use a standardized playing area, and coping with the varied terrains encountered on different courses is a key part of the game. Courses typically have 18 or 9 holes, although they may have another number of holes. Each hole on the course must contain a teeing ground to start from, and a putting green containing the actual hole or cup. There are other standard forms of terrain in between, such as the fairway, rough (long grass), various hazards (water, rocks, bunkers) but each hole on a course is unique in its specific layout and arrangement.Golf is played for the lowest number of strokes by an individual, known as stroke play, or the lowest score on the most individual holes in a complete round by an individual or team, known as match play. Stroke play is the most commonly seen format at all levels, but most especially at the elite level.The modern game of golf originated in 15th century Scotland. The 18-hole round was created at the Old Course at St Andrews in 1764. Golf's first major, and the world's oldest tournament in existence, is The Open Championship, also known as the British Open, which was first played in 1860 at the Prestwick Golf Club in Ayrshire, Scotland. This is one of the four major championships in men's professional golf, the other three being played in the United States: The Masters, the U.S. Open, and the PGA Championship.


The wolf (Canis lupus), also known as the gray wolf or grey wolf, is a large canine native to Eurasia and North America. More than thirty subspecies of "Canis lupus" have been recognized, and gray wolves, as popularly understood, comprise wild subspecies. The wolf is the largest extant member of the family Canidae. It is also distinguished from other "Canis" species by its less pointed ears and muzzle, as well as a shorter torso and a longer tail. The wolf is nonetheless related closely enough to smaller "Canis" species, such as the coyote and the golden jackal, to produce fertile hybrids with them. The banded fur of a wolf is usually mottled white, brown, gray, and black, although subspecies in the arctic region may be nearly all white.Of all members of the genus "Canis", the wolf is most specialized for cooperative game hunting as demonstrated by its physical adaptations to tackling large prey, its more social nature, and its highly advanced expressive behaviour including individual or group howling. It travels in nuclear families consisting of a mated pair accompanied by their offspring. Offspring may leave to form their own packs on the onset of sexual maturity and in response to competition for food within the pack. Wolves are also territorial and fights over territory are among the principal causes of wolf mortality. The wolf is mainly a carnivore and feeds on large wild hooved mammals as well as smaller animals, livestock, carrion, and garbage. Single wolves or mated pairs typically have higher success rates in hunting than do large packs. Pathogens and parasites, notably rabies virus, may infect wolves.The global wild wolf population was estimated to be 300,000 in 2003 and is considered to be of Least Concern by the International Union for Conservation of Nature (IUCN). Wolves have a long history of interactions with humans, having been despised and hunted in most pastoral communities because of their attacks on livestock, while conversely being respected in some agrarian and hunter-gatherer societies. The wolf is also considered the ancestor of the domestic dog. Although the fear of wolves exists in many human societies, the majority of recorded attacks on people have been attributed to animals suffering from rabies. Wolf attacks on humans are rare because wolves are relatively few, live away from people, and have developed a fear of humans because of their experiences with hunters, ranchers, and shepherds.


The olive, botanical name Olea europaea, meaning 'European olive' in Latin, is a species of small tree or shrub in the family Oleaceae, found traditionally in the Mediterranean Basin. When in shrub form, it is known as "Olea europaea" 'Montra', dwarf olive, or little olive. The species is cultivated in all the countries of the Mediterranean, as well as in Australia, New Zealand, North and South America and South Africa. "Olea europaea" is the type species for the genus "Olea".The olive's fruit, also called an "olive", is of major agricultural importance in the Mediterranean region as the source of olive oil; it is one of the core ingredients in Mediterranean cuisine. The tree and its fruit give their name to the plant family, which also includes species such as lilac, jasmine, forsythia, and the true ash tree.Thousands of cultivars of the olive tree are known. Olive cultivars may be used primarily for oil, eating, or both. Olives cultivated for consumption are generally referred to as "table olives". About 90% of all harvested olives are turned into oil, while about 10% are used as table olives.


The coconut tree (Cocos nucifera) is a member of the palm tree family (Arecaceae) and the only living species of the genus "Cocos". The term "coconut" (or the archaic "cocoanut") can refer to the whole coconut palm, the seed, or the fruit, which botanically is a drupe, not a nut. The name comes from the old Portuguese word "coco", meaning "head" or "skull", after the three indentations on the coconut shell that resemble facial features. They are ubiquitous in coastal tropical regions and are a cultural icon of the tropics.The coconut tree provides food, fuel, cosmetics, folk medicine and building materials, among many other uses. The inner flesh of the mature seed, as well as the coconut milk extracted from it, form a regular part of the diets of many people in the tropics and subtropics. Coconuts are distinct from other fruits because their endosperm contains a large quantity of clear liquid, called "coconut water" or "coconut juice". Mature, ripe coconuts can be used as edible seeds, or processed for oil and plant milk from the flesh, charcoal from the hard shell, and coir from the fibrous husk. Dried coconut flesh is called copra, and the oil and milk derived from it are commonly used in cookingfrying in particularas well as in soaps and cosmetics. Sweet coconut sap can be made into drinks or fermented into palm wine or coconut vinegar. The hard shells, fibrous husks and long pinnate leaves can be used as material to make a variety of products for furnishing and decoration.The coconut has cultural and religious significance in certain societies, particularly in the Western Pacific Austronesian cultures where it features in their mythologies, songs, and oral traditions. It also had ceremonial importance in pre-colonial animistic religions. It has also acquired religious significance in South Asian cultures, where it is used in Hindu rituals. It forms the basis of wedding and worship rituals in Hinduism. It also plays a central role in the Coconut Religion of Vietnam. The falling of their mature fruit has led to preoccupation with death by coconut.Coconuts were first domesticated by the Austronesian peoples in Island Southeast Asia and were spread during the Neolithic via their seaborne migrations as far east as the Pacific Islands, and as far west as Madagascar and the Comoros. They played a critical role in the long sea voyages of Austronesians by providing a portable source of food and water, as well as providing building materials for Austronesian outrigger boats. Coconuts were also later spread in historic times along the coasts of the Indian and Atlantic Oceans by South Asian, Arab, and European sailors. Based on these separate introductions, coconut populations can still be divided into Pacific coconuts and Indo-Atlantic coconuts, respectively. Coconuts were introduced by Europeans to the Americas only during the colonial era in the Columbian exchange, but there is evidence of a possible pre-Columbian introduction of Pacific coconuts to Panama by Austronesian sailors. The evolutionary origin of the coconut is under dispute, with theories stating that it may have evolved in Asia, South America, or on Pacific islands. Trees grow up to 30 (m) tall and can yield up to 75 fruits per year, though fewer than 30 is more typical. Plants are intolerant of cold weather and prefer copious precipitation, as well as full sunlight. Many insect pests and diseases affect the species and are a nuisance for commercial production. About 75% of the world's supply of coconuts is produced by Indonesia, the Philippines, and India. The coconut tree is the official state tree of Kerala, India.


The Baltimore oriole (Icterus galbula) is a small icterid blackbird common in eastern North America as a migratory breeding bird. It received its name from the resemblance of the male's colors to those on the coat-of-arms of 17th century Lord Baltimore. Observations of interbreeding between the Baltimore oriole and the western Bullock's oriole, "Icterus bullockii", led to both being classified as a single species, called the northern oriole, from 1973 to 1995. Research by James Rising, a professor of zoology at the University of Toronto, and others showed that the two birds actually did not interbreed significantly.The Baltimore oriole is the state bird of Maryland. It is also the namesake and mascot for the Baltimore Orioles baseball team.


Boat racing is a sport in which boats, or other types of watercraft, race on water. Boat racing powered by oars is recorded as having occurred in ancient Egypt, and it is likely that people have engaged in races involving boats and other water-borne craft for as long as such watercraft have existed.A regatta is a series of boat races. The term comes from the Venetian language, with "regata" meaning "contest" and typically describes racing events of rowed or sailed water craft, although some powerboat race series are also called regattas. A regatta often includes social and promotional activities which surround the racing event, and except in the case of boat type (or "class") championships, is usually named for the town or venue where the event takes place.Although regattas are typically amateur competitions, they are usually formally structured events, with comprehensive rules describing the schedule and procedures of the event. Regattas may be organized as championships for a particular area or type of boat, but are often held just for the joy of competition, camaraderie, and general promotion of the sport.One of the largest and most popular rowing regattas is the Henley Royal Regatta held on the River Thames, England. One of the largest and oldest yachting regattas in the world is Cowes Week, which is held annually by the Royal Yacht Squadron in Cowes, England, and usually attracts over 900 sailing boats. Cowes Week is predated by the Cumberland Cup (1775), Port of Dartmouth Royal Regatta (1822) and Port of Plymouth Regatta (1823). North America's oldest regatta is the Royal St. John's Regatta held on Quidi Vidi Lake in St. John's, Newfoundland every year since 1818.The term "regatta" is from Venetian "regata" ("contention for mastery"), from "regatare" ("compete, haggle, sell at retail"), possibly from "recatare".


Wrens are a family of brown passerine birds in the predominantly New World family Troglodytidae. The family includes 88 species divided into 19 genera. Only the Eurasian wren occurs in the Old World, where, in Anglophone regions, it is commonly known simply as the "wren", as it is the originator of the name. The name "wren" has been applied to other, unrelated birds, particularly the New Zealand wrens (Acanthisittidae) and the Australian wrens (Maluridae).Most wrens are visually inconspicuous (they are the shortest bird in England) though they have loud and often complex songs. Exceptions include the relatively large members of the genus "Campylorhynchus", which can be quite bold in their behaviour. Wrens have short wings that are barred in most species, and they often hold their tails upright. Wrens are primarily insectivorous, eating insects, spiders and other small invertebrates, but many species also eat vegetable matter and some eat small frogs and lizards.


An alligator is a large reptile in the Crocodilia order in the genus Alligator of the family Alligatoridae. The two extant species are the American alligator ("A. mississippiensis") and the Chinese alligator ("A. sinensis"). Additionally, several extinct species of alligator are known from fossil remains. Alligators first appeared during the Oligocene epoch about 37 million years ago. The name "alligator" is probably an anglicized form of "", the Spanish term for "the lizard", which early Spanish explorers and settlers in Florida called the alligator. Later English spellings of the name included "allagarta" and "alagarto".


The Rhode Island Red is an American breed of domestic chicken. It is the state bird of Rhode Island. It was developed there and in Massachusetts in the late nineteenth century, by cross-breeding birds of Oriental origin such as the Malay with brown Leghorn birds from Italy. It was a dual-purpose breed, raised both for meat and for eggs; modern strains have been bred for their egg-laying abilities. The traditional non-industrial strains of the Rhode Island Red are listed as "watch" (medium conservation priority, between "recovering" and "threatened") by The Livestock Conservancy. It is a separate breed to the Rhode Island White.


A hedgehog is a spiny mammal of the subfamily Erinaceinae, in the eulipotyphlan family Erinaceidae. There are seventeen species of hedgehog in five genera found throughout parts of Europe, Asia, and Africa, and in New Zealand by introduction. There are no hedgehogs native to Australia and no living species native to the Americas. However, the extinct genus "Amphechinus" was once present in North America.Hedgehogs share distant ancestry with shrews (family Soricidae), with gymnures possibly being the intermediate link, and they have changed little over the last fifteen million years. Like many of the first mammals, they have adapted to a nocturnal way of life. Their spiny protection resembles that of porcupines, which are rodents, and echidnas, a type of monotreme.


The herons are long-legged, long-necked, freshwater and coastal birds in the family Ardeidae, with 64 recognised species, some of which are referred to as egrets or bitterns rather than herons. Members of the genera "Botaurus" and "Ixobrychus" are referred to as bitterns, and, together with the zigzag heron, or zigzag bittern, in the monotypic genus "Zebrilus", form a monophyletic group within the Ardeidae. Egrets do not form a biologically distinct group from herons, and tend to be named differently because they are mainly white or have decorative plumes in breeding plumage. Herons, by evolutionary adaptation, have long beaks.The classification of the individual heron/egret species is fraught with difficulty, and no clear consensus exists about the correct placement of many species into either of the two major genera, "Ardea" and "Egretta". Similarly, the relationships of the genera in the family are not completely resolved. However, one species formerly considered to constitute a separate monotypic family, the Cochlearidae or the boat-billed heron, is now regarded as a member of the Ardeidae.Although herons resemble birds in some other families, such as the storks, ibises, spoonbills, and cranes, they differ from these in flying with their necks retracted, not outstretched. They are also one of the bird groups that have powder down. Some members of this group nest colonially in trees, while others, notably the bitterns, use reed beds. A group of them is called a "siege."


A hound is a type of hunting dog used by hunters to track or chase prey.


A spaniel is a type of gun dog. Spaniels were especially bred to flush game out of denser brush. By the late 17th century, spaniels had been specialized into water and land breeds. The extinct English Water Spaniel was used to retrieve water fowl shot down with arrows. Land spaniels were setting spaniels—those that crept forward and pointed their game, allowing hunters to ensnare them with nets, and springing spaniels—those that sprang pheasants and partridges for hunting with falcons, and rabbits for hunting with greyhounds. During the 17th century, the role of the spaniel dramatically changed as Englishmen began hunting with flintlocks for wing shooting. Charles Goodall and Julia Gasow (1984) write that spaniels were "transformed from untrained, wild beaters, to smooth, polished gun dogs."
The word "spaniel" would seem to be derived from the medieval French espaigneul—"Spanish"—to modern French, espagnol.


Hereford () is a cathedral city, civil parish and the county town of Herefordshire, England. It lies on the River Wye, approximately 16 (mi) east of the border with Wales, 24 (mi) south-west of Worcester and 23 (mi) north-west of Gloucester. With a population of 60,800, it is by far the largest settlement in Herefordshire.An early town charter from 1189, granted by Richard I of England, describes it as "Hereford in Wales". Hereford has been recognised as a city since time immemorial, with the status being reconfirmed as recently as October 2000.It is now known chiefly as a trading centre for a wider agricultural and rural area. Products from Hereford include cider, beer, leather goods, nickel alloys, poultry, chemicals and sausage rolls, as well as the famous Hereford breed of cattle.


In the English language, black sheep is an idiom that describes a member of a group who is different from the rest, especially a family member who does not fit in. The term stems from sheep whose fleece is colored black rather than the more common white; these sheep stand out in the flock and their wool is worth less as it will not dye.The term has typically been given negative implications, implying waywardness.In psychology, "black sheep effect" refers to the tendency of group members to judge likeable ingroup members more positively and deviant ingroup members more negatively than comparable outgroup members.


Elephants are the largest existing land animals. Three living species are currently recognised: the African bush elephant, the African forest elephant, and the Asian elephant. They are the only surviving members of the family Elephantidae and the order Proboscidea. The order was formerly much more diverse during the Pleistocene, but most species became extinct during the Late Pleistocene epoch. Distinctive features of elephants include a long proboscis called a trunk, tusks, large ear flaps, pillar-like legs, and tough but sensitive skin. The trunk is used for breathing, bringing food and water to the mouth, and grasping objects. Tusks, which are derived from the incisor teeth, serve both as weapons and as tools for moving objects and digging. The large ear flaps assist in maintaining a constant body temperature as well as in communication. African elephants have larger ears and concave backs, whereas Asian elephants have smaller ears, and convex or level backs.Elephants are scattered throughout sub-Saharan Africa, South Asia, and Southeast Asia and are found in different habitats, including savannahs, forests, deserts, and marshes. They are herbivorous, and they stay near water when it is accessible. They are considered to be keystone species, due to their impact on their environments. Elephants have a fission–fusion society, in which multiple family groups come together to socialise. Females (cows) tend to live in family groups, which can consist of one female with her calves or several related females with offspring. The groups, which do not include bulls, are usually led by the oldest cow, known as the matriarch.Males (bulls) leave their family groups when they reach puberty and may live alone or with other males. Adult bulls mostly interact with family groups when looking for a mate. They enter a state of increased testosterone and aggression known as musth, which helps them gain dominance over other males as well as reproductive success. Calves are the centre of attention in their family groups and rely on their mothers for as long as three years. Elephants can live up to 70 years in the wild. They communicate by touch, sight, smell, and sound; elephants use infrasound and seismic communication over long distances. Elephant intelligence has been compared with that of primates and cetaceans. They appear to have self-awareness, and appear to show empathy for dying and dead family members.African bush elephants and Asian elephants are listed as endangered and African forest elephants as critically endangered by the International Union for Conservation of Nature (IUCN). One of the biggest threats to elephant populations is the ivory trade, as the animals are poached for their ivory tusks. Other threats to wild elephants include habitat destruction and conflicts with local people. Elephants are used as working animals in Asia. In the past, they were used in war; today, they are often controversially put on display in zoos, or exploited for entertainment in circuses. Elephants are highly recognisable and have been featured in art, folklore, religion, literature, and popular culture.


Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts.The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods.Most fish are ectothermic ("cold-blooded"), allowing their body temperatures to vary as ambient temperatures change, though some of the large active swimmers like white shark and tuna can hold a higher core temperature. Fish can acoustically communicate with each other, most often in the context of feeding, aggression or courtship. Fish are abundant in most bodies of water. They can be found in nearly all aquatic environments, from high mountain streams (e.g., char and gudgeon) to the abyssal and even hadal depths of the deepest oceans (e.g., cusk-eels and snailfish), although no species has yet been documented in the deepest 25% of the ocean. With 34,300 described species, fish exhibit greater species diversity than any other group of vertebrates.Fish are an important resource for humans worldwide, especially as food. Commercial and subsistence fishers hunt fish in wild fisheries or farm them in ponds or in cages in the ocean (in aquaculture). They are also caught by recreational fishers, kept as pets, raised by fishkeepers, and exhibited in public aquaria. Fish have had a role in culture through the ages, serving as deities, religious symbols, and as the subjects of art, books and movies.Tetrapods (amphibians, reptiles, birds and mammals) emerged within lobe-finned fishes, so cladistically they are fish as well. However, traditionally fish (pisces or ichthyes) are rendered paraphyletic by excluding the tetrapods, and are therefore not considered a formal taxonomic grouping in systematic biology, unless it is used in the cladistic sense, including tetrapods, although usually "vertebrate" is preferred and used for this purpose (fish plus tetrapods) instead. Furthermore, cetaceans, although mammals, have often been considered fish by various cultures and time periods.


Convenient procedures, products and services are those intended to increase ease in accessibility, save resources (such as time, effort and energy) and decrease frustration. A modern convenience is a labor-saving device, service or substance which make a task easier or more efficient than a traditional method. Convenience is a relative concept, and depends on context. For example, automobiles were once considered a convenience, yet today are regarded as a normal part of life.Because differences in lifestyles around the world, the term is a relative term based upon the conveniences previously available to a person or group. For instance, an American definition of 'modern convenience' is likely different from that of an individual living in a developing country. Most of the time, the term 'modern convenience' is used to express personal lifestyle and home life.


In human anatomy, the arm or upper arm is the part of the upper limb between the glenohumeral joint (shoulder joint) and the elbow joint. In common usage, the arm extends through the hand. The arm can be divided into the upper arm, which extends from the shoulder to the elbow, the forearm which extends from the elbow to the hand, and the hand. Anatomically the shoulder girdle with bones and corresponding muscles is by definition a part of the arm. The Latin term "brachium" may refer to either the arm as a whole or to the upper arm on its own.


A weapon, arm or armament is any implement or device that can be used to inflict physical damage, harm, or kill. Weapons are used to increase the efficacy and efficiency of activities such as hunting, crime, law enforcement, self-defense, warfare, or suicide. In broader context, weapons may be construed to include anything used to gain a tactical, strategic, material or mental advantage over an adversary or enemy target.While ordinary objects – sticks, rocks, bottles, chairs, vehicles – can be used as weapons, many objects are expressly designed for the purpose; these range from simple implements such as clubs, axes and swords, to complicated modern firearms, tanks, intercontinental ballistic missiles, biological weapons, and cyberweapons. Something that has been re-purposed, converted, or enhanced to become a weapon of war is termed weaponized, such as a weaponized virus or weaponized laser.


A sprayer is a device used to spray a liquid, where sprayers are commonly used for projection of water, weed killers, crop performance materials, pest maintenance chemicals, as well as manufacturing and production line ingredients. In agriculture, a sprayer is a piece of equipment that is used to apply herbicides, pesticides, and fertilizers on agricultural crops. Sprayers range in size from man-portable units (typically backpacks with spray guns) to trailed sprayers that are connected to a tractor, to self-propelled units similar to tractors with boom mounts of 4 – 30 (feet) up to 60 – 151 (feet) in length depending on engineering design for tractor and land size.


A bag (also known regionally as a sack) is a common tool in the form of a non-rigid container. The use of bags predates recorded history, with the earliest bags being no more than lengths of animal skin, cotton, or woven plant fibers, folded up at the edges and secured in that shape with strings of the same material.Despite their simplicity, bags have been fundamental for the development of human civilization, as they allow people to easily collect loose materials such as berries or food grains, and to transport more items than could readily be carried in the hands. The word probably has its origins in the Norse word "baggi", from the reconstructed Proto-Indo-European bʰak, but is also comparable to the Welsh baich (load, bundle), and the Greek Τσιαντουλίτσα ("Chandulícha", load).Cheap disposable paper bags and plastic shopping bags are very common in the retail trade as a convenience for shoppers, and are often supplied by the shop for free or for a small fee. Customers may also take their own shopping bags to use in shops, these are more commonly known as tote bags or shoppers tote. Although, paper had been used for purposes of wrapping and padding in ancient China since the 2nd century BC, the first use of paper bags (for preserving the flavor of tea) in China came during the later Tang Dynasty (618–907 AD).


Barge nowadays generally refers to a flat-bottomed inland waterway vessel which does not have its own means of mechanical propulsion. The first modern barges were pulled by tugs, but nowadays most are pushed by pusher boats, or other vessels. The term barge has a rich history, and therefore there are many other types of barges.


A basket is a container that is traditionally constructed from stiff fibers and can be made from a range of materials, including wood splints, runners, and cane. While most baskets are made from plant materials, other materials such as horsehair, baleen, or metal wire can be used. Baskets are generally woven by hand. Some baskets are fitted with a lid, while others are left open on top.


A batting helmet is worn by batters in the game of baseball or softball. It is meant to protect the batter's head from errant pitches thrown by the pitcher. A batter who is "hit by pitch," due to an inadvertent wild pitch or by intent, may be seriously, even fatally, injured.


A bell tower is a tower that contains one or more bells, or that is designed to hold bells even if it has none. Such a tower commonly serves as part of a Christian church, and will contain church bells, but there are also many secular bell towers, often part of a municipal building, an educational establishment, or a tower built specifically to house a carillon. Church bell towers often incorporate clocks, and secular towers usually do, as a public service.The term campanile (, , ), deriving from the Italian "campanile", which in turn derives from "campana", meaning "bell", is synonymous with "bell tower"; though in English usage campanile tends to be used to refer to a free standing bell tower. A bell tower may also in some traditions be called a belfry, though this term may also refer specifically to the substructure that houses the bells and the ringers rather than the complete tower.The tallest free-standing bell tower in the world, 113.2 (m) high, is the Mortegliano Bell Tower, in the Friuli Venezia Giulia region, Italy.


A bicycle seat, unlike a bicycle saddle, is designed to support the rider's buttocks and back, usually in a semi-reclined position. Arthur Garford is credited with inventing the padded bicycle seat in 1892, and they are now usually found on recumbent bicycles.Bicycle seats come in three main styles; mesh, hardshell and combination


A visor (also spelled vizor) is a surface that protects the eyes, such as shading them from the sun or other bright light or protecting them from objects.Nowadays many visors are transparent, but before strong transparent substances such as polycarbonate were invented, visors were opaque like a maskThe part of a helmet in a suit of armor that protects the eyes.A type of headgear consisting only of a visor and a band as a way to fasten it around the head.Any such vertical surface on any hat or helmet.Any such horizontal surface on any hat or helmet (called a "peak" in British English).A device in an automobile that the driver or front passenger can lower over part of the windshield to block the sun (sun visor).


A boot is a type of footwear. Most boots mainly cover the foot and the ankle, while some also cover some part of the lower calf. Some boots extend up the leg, sometimes as far as the knee or even the hip. Most boots have a heel that is clearly distinguishable from the rest of the sole, even if the two are made of one piece. Traditionally made of leather or rubber, modern boots are made from a variety of materials. Boots are worn both for their functionality and for reasons of style and fashion. Functional concerns include: protection of the foot and leg from water, mud, pestilence (infectious disease, insect bites and stings, snake bites), extreme temperatures, sharp or blunt hazards (e.g. work boots may provide steel toes), physical abrasion, corrosive agents, or damaging radiation; ankle support and traction for strenuous activities such as hiking; and durability in harsh conditions (e.g. the underside of combat boots may be reinforced with hobnails). In some cases, the wearing of boots may be required by laws or regulations, such as the regulations in some jurisdictions requiring workers on construction sites to wear steel-toed safety boots. Some uniforms include boots as the regulated footwear. Boots are recommended as well for motorcycle riders. High-top athletic shoes are generally not considered boots, even though they do cover the ankle, primarily due to the absence of a distinct heel. In Britain football (soccer) cleats are also called boots.


Bread knives are used for cutting bread and are one of many kitchen knives used by cooks. The serrated blades of bread knives are able to cut soft bread without crushing it.


A bridle is a piece of equipment used to direct a horse. As defined in the "Oxford English Dictionary", the "bridle" includes both the that holds a bit that goes in the mouth of a horse, and the reins that are attached to the bit.Headgear without a bit that uses a noseband to control a horse is called a hackamore, or, in some areas, a bitless bridle. There are many different designs with many different name variations, but all use a noseband that is designed to exert pressure on sensitive areas of the animal's face to provide direction and control.


A bulldozer or dozer (also called a crawler) is a large, motorized machine equipped with a metal blade to the front for pushing material: soil, sand, snow, rubble, or rock during construction work. It travels most commonly on continuous tracks, though specialized models riding on large are also produced. Its most popular accessory is a ripper, a large hook-like device mounted singly or in multiples in the rear to loosen dense materials. Bulldozers are used heavily in large and small scale construction, road building, minings and quarrying, on farms, in heavy industry factories, and in military applications in both peace and wartime.The word "bulldozer" refers only to a motorized unit fitted with a blade designed for pushing. The word is sometimes used inaccurately for other heavy equipment such as a front-end loader designed for carrying rather than pushing material.


A cage is an enclosure often made of mesh, bars, or wires, used to confine, contain or protect something or someone. A cage can serve many purposes, including keeping an animal or person in captivity, capturing an animal or person, and displaying an animal at a zoo.


A food truck is a large motorized vehicle (such as a van) or trailer, equipped to cook, prepare, serve, and/or sell food. Some, including ice cream trucks, sell frozen or prepackaged food; others have on-board kitchens and prepare food from scratch, or they heat up food that was prepared in a brick and mortar commercial kitchen. Sandwiches, hamburgers, french fries, and other regional fast food fare is common. By the early 2010s, amid the pop-up restaurant phenomenon, food trucks offering gourmet cuisine and a variety of specialties and ethnic menus became particularly popular. Food trucks may also sell cold beverages such as soda pop and water. Food trucks, along with food booths and food carts, are major components of the street food industry that serves an estimated 2.5 billion people every day.


A cash register, sometimes called a till or automated money handling system, is a mechanical or electronic device for registering and calculating transactions at a point of sale. It is usually attached to a drawer for storing cash and other valuables. A modern cash register is usually attached to a printer that can print out receipts for record-keeping purposes.


Pottery is the process and the products of forming vessels and other objects with clay and other ceramic materials, which are fired at high temperatures to give them a hard and durable form. Major types include earthenware, stoneware and porcelain. The place where such wares are made by a "potter" is also called a "pottery" (plural "potteries"). The definition of "pottery", used by the ASTM International, is "all fired ceramic wares that contain clay when formed, except technical, structural, and refractory products." In art history and archaeology, especially of ancient and prehistoric periods, "pottery" often means vessels only, and sculpted figurines of the same material are called "terracottas". Pottery is one of the oldest human inventions, originating before the Neolithic period, with ceramic objects like the Gravettian culture Venus of Dolní Věstonice figurine discovered in the Czech Republic dating back to 29,000–25,000 BC, and pottery vessels that were discovered in Jiangxi, China, which date back to 18,000 BC. Early Neolithic and pre-Neolithic pottery artifacts have been found, in Jōmon Japan (10,500 BC), the Russian Far East (14,000 BC), Sub-Saharan Africa (9,400 BC), South America (9,000s–7,000s BC), and the Middle East (7,000s–6,000s BC).Pottery is made by forming a ceramic (often clay) body into objects of a desired shape and heating them to high temperatures (600–1600 °C) in a bonfire, pit or kiln and induces reactions that lead to permanent changes including increasing the strength and rigidity of the object. Much pottery is purely utilitarian, but some can also be regarded as ceramic art. A clay body can be decorated before or after firing.Clay-based pottery can be divided into three main groups: earthenware, stoneware and porcelain. These require increasingly more specific clay material, and increasingly higher firing temperatures. All three are made in glazed and unglazed varieties, for different purposes. All may also be decorated by various techniques. In many examples the group a piece belongs to is immediately visually apparent, but this is not always the case. The fritware of the Islamic world does not use clay, so technically falls outside these groups. Historic pottery of all these types is often grouped as either "fine" wares, relatively expensive and well-made, and following the aesthetic taste of the culture concerned, or alternatively "coarse", "popular", "folk" or "village" wares, mostly undecorated, or simply so, and often less well-made.Cooking in clay pots became less popular once metal pots became available, but is still used for dishes that depend on the qualities of pottery cooking, such as biryani, cassoulet, daube, tagine, jollof rice, kedjenou, cazuela, and baked beans.


A chandelier (; also known as girandole, candelabra lamp, or least commonly suspended lights) is a branched ornamental light fixture designed to be mounted on ceilings or walls. Chandeliers are often ornate, and normally use incandescent light bulbs, though some modern designs also use fluorescent lamps and recently LEDs.Classic chandeliers have arrays of hanging crystal prisms to illuminate a room with refracted light, while contemporary chandeliers assume a more minimalist design that does not contain prisms and illuminate a room with direct light from the lamps, sometimes also equipped with translucent glass covering each lamp. Modern chandeliers have a more modernized design that uses LEDs, and combines the elements of both classic and contemporary designs; some are also equipped with refractive crystal prisms or small mirrors.Chandeliers are distinct from pendant lights, as they usually consist of multiple lamps and hang in branched frames, whereas pendant lights hang from a single cord and only contain one or two lamps with fewer decorative elements. Due to their size, they are often installed in hallways, living rooms, staircases, lounges, and dining rooms. However, miniature chandeliers also exist, which can be installed in smaller spaces such as bedrooms or small living spaces. The most typical places for larger chandeliers are churches or cathedrals.Chandeliers evolved from candelabra and were invented during the medieval period. They originally used candles as their source of light, which remained in use until the 18th century, when gas lights, later superseded by electric lights, were invented.


A doll is a model typically of a human or humanoid character, often used as a toy for children, especially little girls. Dolls have also been used in traditional religious rituals throughout the world. Traditional dolls made of materials such as clay and wood are found in the Americas, Asia, Africa and Europe. The earliest documented dolls go back to the ancient civilizations of Egypt, Greece, and Rome. They have been made as crude, rudimentary playthings as well as elaborate art. Modern doll manufacturing has its roots in Germany, from the 15th century. With industrialization and new materials such as porcelain and plastic, dolls were increasingly mass-produced. During the 20th century, dolls became increasingly popular as collectibles.


A dump truck, known also as a dumping truck, dump trailer, dumper trailer, dump lorry or dumper lorry or a dumper for short, is used for transporting materials (such as dirt, gravel, or demolition waste) for construction as well as coal. A typical dump truck is equipped with an open-box bed, which is hinged at the rear and equipped with hydraulic rams to lift the front, allowing the material in the bed to be deposited ("dumped") on the ground behind the truck at the site of delivery. In the UK, Australia, South Africa and India the term applies to off-road construction plants only and the road vehicle is known as a tip lorry, tipper lorry (UK, India), tipper truck, tip truck, tip trailer or tipper trailer or simply a tipper (Australia, New Zealand, South Africa).


Earmuffs are clothing accessories or personal protective equipment designed to cover a person's ears for hearing protection or for warmth. They consist of a thermoplastic or metal head-band, that fits over the top or back of the head, and a cushion or cup at each end, to cover the external ears.


In the field of textiles, fishnet is hosiery with an open, diamond-shaped knit; it is most often used as a material for stockings, tights, gloves or bodystockings. Fishnet is available in a multitude of colors, although it is most often sported in traditional matte black. Fishnet is commonly worn on the legs and arms by practitioners of goth and punk fashion, but is also commonly worn by the mainstream as a fashion statement. Generally considered to be a sexy garment, it may serve as a component of sexual fetishism. Fishnets are used mostly as a type of undergarment, and in as much as it defines curves by applying a grid close to the body it generally accentuates the wearer's muscular definition.A more practical use of fishnet textiles is in high performance next-to-skin apparel used in cold weather outdoor sports, including hiking, hunting, fishing, skiing, and mountaineering. In this context, fishnet is usually knitted from fibers of polypropylene, merino wool, or nylon, and offers a number of benefits over traditional densely knitted base layer apparel. These benefits are related to the presence of large void spaces in the fishnet fabric structure that trap insulating air for warmth in cool conditions, and allow for the rapid transport of moisture from the skin surface to outer layers to minimize conductive heat loss.


Goggles, or safety glasses, are forms of protective eyewear that usually enclose or protect the area surrounding the eye in order to prevent particulates, water or chemicals from striking the eyes. They are used in chemistry laboratories and in woodworking. They are often used in snow sports as well, and in swimming. Goggles are often worn when using power tools such as drills or chainsaws to prevent flying particles from damaging the eyes. Many types of goggles are available as prescription goggles for those with vision problems.


A hatchback is a car body configuration with a rear door that swings upward to provide access to a cargo area. Hatchbacks may feature fold-down second row seating, where the interior can be reconfigured to prioritize passenger or cargo volume. Hatchbacks may feature two- or three-box design.While early examples of the body configuration can be traced to the 1930s, the Merriam-Webster dictionary dates the term itself to 1970.The hatchback body style has been marketed worldwide on cars ranging in size from superminis to small family cars, as well as executive cars and some sports cars. They are a primary component on a sport utility vehicle.


Headgear, headwear, or headdress is the name given to any element of clothing which is worn on one's head, including hats, helmets, turbans and many other types. Headgear is worn for many purposes, including protection against the elements, decoration, or for religious or cultural reasons, including social conventions.


A hedge or hedgerow is a line of closely spaced shrubs and sometimes trees, planted and trained to form a barrier or to mark the boundary of an area, such as between neighbouring properties. Hedges that are used to separate a road from adjoining fields or one field from another, and are of sufficient age to incorporate larger trees, are known as hedgerows. Often they serve as windbreaks to improve conditions for the adjacent crops, as in bocage country. When clipped and maintained, hedges are also a simple form of topiary.A hedge often operates as, and sometimes is called, a "live fence". This may either consist of individual fence posts connected with wire or other fencing material, or it may be in the form of densely planted hedges without interconnecting wire. This is common in tropical areas where low-income farmers can demarcate properties and reduce maintenance of fence posts that otherwise deteriorate rapidly. Many other benefits can be obtained depending on the species chosen.


A high chair is a piece of furniture used for feeding older babies and younger toddlers. The seat is raised a fair distance from the ground, so that a person of adult height may spoon-feed the child comfortably from a standing position (hence the name). It often has a wide base to increase stability. There is a tray which is attached to the arms of the high chair, which allows the adult to place the food on it for either the child to pick up and eat or for the food to be spoon-fed to them.A booster chair is meant to be used with a regular chair to boost the height of a child sufficiently. Some boosters are a simple monolithic piece of plastic. Others are more complex and are designed to fold up and include a detachable tray.Rarely, a chair can be suspended from the edge of the table avoiding the need for an adult chair or a high chair.


A horseshoe is a fabricated product, normally made of metal, although sometimes made partially or wholly of modern synthetic materials, designed to protect a horse hoof from wear. Shoes are attached on the palmar surface (ground side) of the hooves, usually nailed through the insensitive hoof wall that is anatomically akin to the human toenail, although much larger and thicker. However, there are also cases where shoes are glued.The fitting of horseshoes is a professional occupation, conducted by a farrier, who specializes in the preparation of feet, assessing potential lameness issues, and fitting appropriate shoes, including remedial features where required. In some countries, such as the UK, horseshoeing is legally restricted to people with specific qualifications and experience. In others, such as the United States, where professional licensing is not legally required, professional organizations provide certification programs that publicly identify qualified individuals.Horseshoes are available in a wide variety of materials and styles, developed for different types of horse and for the work they do. The most common materials are steel and aluminium, but specialized shoes may include use of rubber, plastic, magnesium, titanium, or copper. Steel tends to be preferred in sports in which a strong, long-wearing shoe is needed, such as polo, eventing, show jumping, and western riding events. Aluminium shoes are lighter, making them common in horse racing where a lighter shoe is desired, and often facilitate certain types of movement; they are often favored in the discipline of dressage. Some horseshoes have "caulkins", "caulks", or "calks": protrusions at the toe or heels of the shoe, or both, to provide additional traction.When kept as a talisman, a horseshoe is said to bring good luck. A stylized variation of the horseshoe is used for a popular throwing game, horseshoes.


A hot air balloon is a lighter-than-air aircraft consisting of a bag, called an envelope, which contains heated air. Suspended beneath is a gondola or wicker basket (in some long-distance or high-altitude balloons, a capsule), which carries passengers and a source of heat, in most cases an open flame caused by burning liquid propane. The heated air inside the envelope makes it buoyant, since it has a lower density than the colder air outside the envelope. As with all aircraft, hot air balloons cannot fly beyond the atmosphere. The envelope does not have to be sealed at the bottom, since the air inside the envelope is at about the same pressure as the surrounding air. In modern sport balloons the envelope is generally made from nylon fabric, and the inlet of the balloon (closest to the burner flame) is made from a fire-resistant material such as Nomex. Modern balloons have been made in many shapes, such as rocket ships and the shapes of various commercial products, though the traditional shape is used for most non-commercial and many commercial applications.The hot air balloon is the first successful human-carrying flight technology. The first untethered manned hot air balloon flight was performed by Jean-François Pilâtre de Rozier and François Laurent d'Arlandes on November 21, 1783, in Paris, France, in a balloon created by the Montgolfier brothers. The first hot air balloon flown in the Americas was launched from the Walnut Street Jail in Philadelphia on January 9, 1793, by the French aeronaut Jean Pierre Blanchard. Hot air balloons that can be propelled through the air rather than simply drifting with the wind are known as thermal airships.


A jumpsuit is a one-piece garment with sleeves and legs and typically without integral coverings for feet, hands or head. The original jump suit is the functional one-piece garment used by parachuters. The original skydivers' jumpsuits were simple garments designed to insulate the body from the colder temperature that's associated with higher altitudes and minimize the risk of covering important handles and grips. Today, however, the garment has found other uses.Jumpsuits are generally regarded as a garment of convenience, especially for entertainers, as they are simpler, lighter and more flexible to wear. They have become more of a put on and remove garment than an ensemble outfit. However, unless the jumpsuit has an opening on the rear (a "drop seat"), it is necessary to remove it entirely for bathroom use.


A knife (plural knives; from Old Norse 'knife, dirk') is a tool or weapon with a cutting edge or blade, usually attached to a handle or hilt. One of the earliest tools used by humanity, knives appeared at least 2.5 million years ago, as evidenced by the Oldowan tools. Originally made of wood, bone, and stone (such as flint and obsidian), over the centuries, in step with improvements in both metallurgy and manufacturing, knife blades have been made from copper, bronze, iron, steel, ceramic, and titanium. Most modern knives have either fixed or folding blades; blade patterns and styles vary by maker and country of origin.Knives can serve various purposes. Hunters use a hunting knife, soldiers use the combat knife, scouts, campers, and hikers carry a pocket knife; there are kitchen knives for preparing foods (the chef's knife, the paring knife, bread knife, cleaver), table knives (butter knives and steak knives), weapons (daggers or switchblades), knives for throwing or juggling, and knives for religious ceremony or display (the kirpan).


A lookout or look-out is a person in charge of the observation of hazards. The term originally comes from a naval background, where lookouts would watch for other ships, land, and various dangers. The term has now passed into wider parlance.


A public toilet, restroom, public bathroom or washroom is a room or small building with toilets (or urinals) and sinks for use by the general public. The facilities are available to customers, travelers, employees of a business, school pupils and prisoners and are commonly separated into male and female toilets, although some are unisex, especially for small or single-occupancy public toilets.Increasingly, public toilets are accessible to people with disabilities. Depending on the culture, there may be varying degrees of separation between males and females and different levels of privacy. Typically, the entire room, or a stall or cubicle containing a toilet, is lockable. Urinals, if present in a male toilet, are typically mounted on a wall with or without a divider between them. Local authorities or commercial businesses may provide public toilet facilities. Some are unattended while others are staffed by an attendant. In many cultures, it is customary to tip the attendant, especially if they provide a specific service, such as might be the case at upscale nightclubs or restaurants.Public toilets are typically found in many different places: inner-city locations, offices, factories, schools, universities and other places of work and study. Similarly, museums, cinemas, bars, restaurants, entertainment venues usually provide public toilets. Railway stations, filling stations, and long distance public transport vehicles such as trains, ferries, and planes usually provide toilets for general use. Portable toilets are often available at large outdoor events.Public toilets may be municipally owned or managed and entered directly from the street. Or they may be within a building that, while privately owned, allows public access, such as a department store, or it may be limited to the business's customers, such as a restaurant. Some public toilets are free of charge while others charge a fee. In the latter case they are also called pay toilets and sometimes have a charging turnstile. In the most basic form, a public toilet may just be a street urinal known as a "pissoir", after the French term.Public toilets are known by many other names depending on the country. Examples are: restroom, bathroom, men's room, women's room, powder room in the US, washroom in Canada, and toilets, lavatories, water closet (W.C.), ladies and gents in Europe.


A metronome, from ancient Greek μέτρον ("métron", "measure") and νομός (nomós, "custom", "melody") is a device that produces an audible click or other sound at a regular interval that can be set by the user, typically in beats per minute (BPM). Metronomes may include synchronized visual motion. Musicians use the device to practise playing to a regular pulse.A kind of metronome was among the inventions of Andalusian polymath Abbas ibn Firnas (810–887). In 1815, German inventor Johann Maelzel patented his mechanical, wind-up metronome as a tool for musicians, under the title "Instrument/Machine for the Improvement of all Musical Performance, called Metronome". In the 20th century, electronic metronomes and software metronomes were invented.Musicians practise with metronomes to improve their timing, especially the ability to stick to a regular tempo. Metronome practice helps internalize a clear sense of timing and tempo. Composers and conductors often use a metronome as a standard tempo reference—and may play, sing, or conduct to the metronome. The metronome is used by composers to derive beats per minute if they want to indicate that in a composition. Conductors use a metronome to note their preferred tempo in each section.When interpreting emotion and other qualities in music, performers seldom play exactly on every beat; expressive, flexible rubato may be used at times. Typically, every beat of a musically expressive performance does not align exactly with each click of a metronome. This has led some musicians to criticize use of a metronome, because "metronome time" is different from "musical time".


An oven is a tool which is used to expose materials to a hot environment. Ovens contain a hollow chamber and provide a means of heating the chamber in a controlled way. In use since antiquity, they have been used to accomplish a wide variety of tasks requiring controlled heating. Because they are used for a variety of purposes, there are many different types of ovens. These types differ depending on their intended purpose and based upon how they generate heat.Ovens are often used for cooking, where they can be used to heat food to a desired temperature. Ovens are also used in the manufacturing of ceramics and pottery; these ovens are sometimes referred to as kilns. Metallurgical furnaces are ovens used in the manufacturing of metals, while glass furnaces are ovens used to produce glass.There are many methods by which different types of ovens produce heat. Some ovens heat materials using the combustion of a fuel, such as wood, coal, or natural gas, while many employ electricity. Microwave ovens heat materials by exposing them to microwave radiation while electric ovens and electric furnaces heat materials using resistive heating. Some ovens use forced convection, the movement of gases inside the heating chamber, to enhance the heating process, or, in some cases, to change the properties of the material being heated, such as in the Bessemer method of steel production.


An overpass (called an overbridge or flyover in the United Kingdom and some other Commonwealth countries) is a bridge, road, railway or similar structure that crosses over another road or railway. An "overpass" and "underpass" together form a grade separation. Stack interchanges are made up of several overpasses.


Parasailing, also known as parascending, paraskiing or parakiting, is a recreational kiting activity where a person is towed behind a vehicle while attached to a specially designed canopy wing that resembles a parachute, known as a parasail wing. The manned kite's moving anchor may be a car, truck, or boat. The harness attaches the occupant to the parasail, which is connected to the boat, or land vehicle, by the tow rope. The vehicle then drives off, carrying the parascender (or wing) and person into the air. If the boat is powerful enough, two or three people can parasail behind it at the same time. The parascender has little or no control over the parachute. The activity is primarily a fun ride, not to be confused with the sport of paragliding.There are commercial parasailing operations all over the world. Land-based parasailing has also been transformed into a competition sport in Europe. In land-based competition parasailing, the parasail is towed to maximum height behind a 4-wheel-drive vehicle. The driver then releases the tow line; the parasailer flies down to a target area in an accuracy competition.The sport was developed in the late 1970s, and has been very popular ever since. The first international competitions were held in the mid-1980s and continue annually to this day. Over the years, the competitions have grown in scope as well as the number of participants.


A parka or anorak is a type of coat with a hood, often lined with fur or faux fur. This kind of garment is a staple of Inuit clothing, traditionally made from caribou or seal skin, for hunting and kayaking in the frigid Arctic. Some Inuit anoraks require regular coating with fish oil to retain their water resistance.The words "anorak" and "parka" have been used interchangeably, but they are somewhat different garments. Strictly speaking, an anorak is a waterproof, hooded, pull-over jacket without a front opening, and sometimes drawstrings at the waist and cuffs, and a parka is a hip-length cold-weather coat, typically stuffed with down or very warm synthetic fiber, and with a fur-lined hood.


The pith helmet, also known as the safari helmet, salacot, sola topee, sun helmet, topee, and topi) is a lightweight cloth-covered helmet made of sholapith. The pith helmet originates from the Spanish military adaptation of the native "salakot" headgear of the Philippines.It was often worn by European travellers and explorers, in the varying climates found in Southeast Asia, Africa, and the tropics, but was also used in many other contexts. It was routinely issued to European military personnel serving overseas in hot climates from the mid-nineteenth to the mid-twentieth century.


Plywood is a material manufactured from thin layers or "plies" of wood veneer that are glued together with adjacent layers having their wood grain rotated up to 90 degrees to one another. It is an engineered wood from the family of manufactured boards which include medium-density fibreboard (MDF), oriented strand board (OSB) and particle board (chipboard).All plywoods bind resin and wood fibre sheets (cellulose cells are long, strong and thin) to form a composite material. This alternation of the grain is called "cross-graining" and has several important benefits: it reduces the tendency of wood to split when nailed at the edges; it reduces expansion and shrinkage, providing improved dimensional stability; and it makes the strength of the panel consistent across all directions. There is usually an odd number of plies, so that the sheet is balanced—this reduces warping. Because plywood is bonded with grains running against one another and with an odd number of composite parts, it has high stiffness perpendicular to the grain direction of the surface ply. Smaller, thinner, and lower quality plywoods may only have their plies (layers) arranged at right angles to each other. Some better-quality plywood products will by design have five plies in steps of 45 degrees (0, 45, 90, 135, and 180 degrees), giving strength in multiple axes.The word "ply" derives from the French verb , "to fold", from the Latin verb , from the ancient Greek verb .


A powder is a dry, bulk solid composed of many very fine particles that may flow freely when shaken or tilted. Powders are a special sub-class of granular materials, although the terms "powder" and "granular" are sometimes used to distinguish separate classes of material. In particular, "powders" refer to those granular materials that have the finer grain sizes, and that therefore have a greater tendency to form clumps when flowing. "Granulars" refers to the coarser granular materials that do not tend to form clumps except when wet.


A robe is a loose-fitting outer garment. Unlike garments described as capes or cloaks, robes usually have sleeves. The English word "robe" derives from Middle English "robe" ("garment"), borrowed from Old French "robe" ("booty, spoils"), itself taken from the Frankish word *"rouba" ("spoils, things stolen, clothes"), and is related to the word "rob".


A sailboat or sailing boat is a boat propelled partly or entirely by sails and is smaller than a sailing ship. Distinctions in what constitutes a sailing boat and ship vary by region and maritime culture.


Scissors are hand-operated shearing tools. A pair of scissors consists of a pair of metal blades pivoted so that the sharpened edges slide against each other when the handles (bows) opposite to the pivot are closed. Scissors are used for cutting various thin materials, such as paper, cardboard, metal foil, cloth, rope, and wire. A large variety of scissors and shears all exist for specialized purposes. Hair-cutting shears and kitchen shears are functionally equivalent to scissors, but the larger implements tend to be called shears. Hair-cutting shears have specific blade angles ideal for cutting hair. Using the incorrect type of scissors to cut hair will result in increased damage or split ends, or both, by breaking the hair. Kitchen shears, also known as kitchen scissors, are intended for cutting and trimming foods such as meats.Inexpensive, mass-produced modern scissors are often designed ergonomically with composite thermoplastic and rubber handles.


A screen door can refer to a hinged storm door (cold climates) or hinged screen door (warm climates) covering an exterior door, or a screened sliding door used with sliding glass doors. In any case, the screen door incorporates screen mesh to block birds, flying insects or airborne debris such as seeds or leaves from entering, and pets and small children from exiting interior spaces, while allowing for air, light, and views.


Snowshoes are specialized outdoor gear for walking over snow. Their large footprint spreads the user's weight out and allows them to travel largely on top of rather than through snow. Adjustable bindings attach them to appropriate winter footwear. Traditional snowshoes have a hardwood frame filled in with rawhide latticework. Modern snowshoes are made of lightweight metal, plastic, and other synthetic materials.In the past, snowshoes were essential equipment for anyone dependent on travel in deep and frequent snowfall, such as fur trappers. They retain that role in areas where motorized vehicles cannot reach or are inconvenient to use. However, their greatest contemporary use is for recreation.Snowshoeing is easy to learn and in appropriate conditions is a relatively safe and inexpensive recreational activity. However, doing so in icy, steep terrain requires both advanced skill and mountaineering-style pivoting-crampon snowshoes.


A squeegee or squilgee is a tool with a flat, smooth rubber blade, used to remove or control the flow of liquid on a flat surface. It is used for cleaning and in printing.The earliest written references to squeegees date from the mid-19th century and concern deck-cleaning tools, some with leather rather than rubber blades. The name "squeegee" may come from the word "squeege", meaning press or squeeze, which was first recorded in 1783. The closely related "squeedging" was reportedly first used in 1782, in the Covent Garden Theatre, during the performing of the comedy "Which is the Man?" by Hannah Cowley.


Strapless is a 1989 film written and directed by David Hare.


Surveillance is the monitoring of behavior, many activities, or information for the purpose of information gathering, influencing, managing or directing. This can include observation from a distance by means of electronic equipment, such as closed-circuit television (CCTV), or interception of electronically transmitted information like Internet traffic. It can also include simple technical methods, such as human intelligence gathering and postal interception.Surveillance is used by citizens for protecting their neighborhoods. And by governments for intelligence gathering - including espionage, prevention of crime, the protection of a process, person, group or object, or the investigation of crime. It is also used by criminal organizations to plan and commit crimes, and by businesses to gather intelligence on criminals, their competitors, suppliers or customers. Religious organisations charged with detecting heresy and heterodoxy may also carry out surveillance.Auditors carry out a form of surveillance.A byproduct of surveillance is that it can unjustifiably violate people's privacy and is often criticized by civil liberties activists. Liberal democracies may have laws that seek to restrict governmental and private use of surveillance, whereas authoritarian governments seldom have any domestic restrictions. Espionage is by definition covert and typically illegal according to the rules of the observed party, whereas most types of surveillance are overt and are considered legitimate. International espionage seems to be common among all types of countries.


A thermostat is a regulating device component which senses the temperature of a physical system and performs actions so that the system's temperature is maintained near a desired setpoint.Thermostats are used in any device or system that heats or cools to a setpoint temperature, examples include building heating, central heating, air conditioners, HVAC systems, water heaters, as well as kitchen equipment including ovens and refrigerators and medical and scientific incubators. In scientific literature, these devices are often broadly classified as thermostatically controlled loads (TCLs). Thermostatically controlled loads comprise roughly 50% of the overall electricity demand in the United States. A thermostat operates as a "closed loop" control device, as it seeks to reduce the error between the desired and measured temperatures. Sometimes a thermostat combines both the sensing and control action elements of a controlled system, such as in an automotive thermostat.The word thermostat is derived from the Greek words θερμός "thermos", "hot" and στατός "statos", "standing, stationary".


In rail transport, a train (from Old French , from Latin , "to pull, to draw") is a series of connected vehicles that run along a railway track and transport people or freight. Trains are typically pulled or pushed by locomotives (often known simply as "engines"), though some are self-propelled, such as multiple units. Passengers and cargo are carried in railroad cars, also known as wagons. Trains are designed to a certain gauge, or distance between rails. Most trains operate on steel tracks with steel wheels, the low friction of which makes them more efficient than other forms of transport.Trains have their roots in wagonways, which used railway tracks and were powered by horses or pulled by cables. Following the invention of the steam locomotive in the United Kingdom in 1804, trains rapidly spread around the world, allowing freight and passengers to move over land faster and cheaper than ever possible before. Rapid transit and trams were first built in the late 1800s to transport large numbers of people in and around cities. Beginning in the 1920s, and accelerating following World War II, diesel and electric locomotives replaced steam as the means of motive power. Following the development of cars, trucks, and extensive networks of highways which offered greater mobility, as well as faster airplanes, trains declined in importance and market share, and many rail lines were abandoned. The spread of buses led to the closure of many rapid transit and tram systems during this time as well.Since the 1970s, governments, environmentalists, and train advocates have promoted increased use of trains due to their greater fuel efficiency and lower greenhouse gas emissions compared to other modes of land transport. High-speed rail, first built in the 1960s, has proven competitive with cars and planes over short to medium distances. Commuter rail has grown in importance since the 1970s as an alternative to congested highways and a means to promote development, as has light rail in the 21st century. Freight trains remain important for the transport of bulk commodities such as coal and grain, as well as being a means of reducing road traffic congestion by freight trucks.While conventional trains operate on relatively flat tracks with two rails, a number of specialized trains exist which are significantly different in their mode of operation. Monorails operate on a single rail, while funiculars and rack railways are uniquely designed to traverse steep slopes. Experimental trains such as high speed maglevs, which use magnetic levitation to float above a guideway, are under development in the 2020s and offer higher speeds than even the fastest conventional trains. Development of trains which use alternative fuels such as natural gas and hydrogen is another 21st century development.


The ukulele ( ; from , ), also called Uke, is a member of the lute family of instruments of Portuguese origin and popularized in Hawaii. It generally employs four nylon strings.The tone and volume of the instrument vary with size and construction. Ukuleles commonly come in four sizes: soprano, concert, tenor, and baritone.


A suitcase is a form of luggage. It is often a somewhat flat, rectangular-shaped bag with rounded square corners. Vinyl, leather or cloth suitcases may have a metal frame. Hardshell suitcases open on hinges like a door.


Wicker is the oldest furniture making method known to history, dating as far back as 5,000 years ago. It was first documented in ancient Egypt using pliable plant material, but in modern times it is made from any pliable, easily woven material. The word "wicker" or "wisker" is believed to be of Scandinavian origin: , which means "to fold" in Swedish, and meaning willow. Wicker is traditionally made of material of plant origin, such as willow, rattan, reed, and bamboo, but synthetic fibers are now also used. Wicker is light yet sturdy, making it suitable for items that will be moved often like porch and patio furniture. "Rushwork" and wickerwork are terms used in England. A typical braiding pattern is called "Wiener Geflecht", Viennese Braiding, as it was invented in 18th century Vienna and later most prominently used with the Thonet coffeehouse chair.


The windshield (North American English) or windscreen (Commonwealth English) of an aircraft, car, bus, motorbike, truck, train, boat or streetcar is the front window, which provides visibility while protecting occupants from the elements. Modern windshields are generally made of laminated safety glass, a type of treated glass, which consists of, typically, two curved sheets of glass with a plastic layer laminated between them for safety, and bonded into the window frame.Motorcycle windshields are often made of high-impact polycarbonate or acrylic plastic.


Electrical wiring is an electrical installation of cabling and associated devices such as switches, distribution boards, sockets, and light fittings in a structure.Wiring is subject to safety standards for design and installation. Allowable wire and cable types and sizes are specified according to the circuit operating voltage and electric current capability, with further restrictions on the environmental conditions, such as ambient temperature range, moisture levels, and exposure to sunlight and chemicals.Associated circuit protection, control, and distribution devices within a building's wiring system are subject to voltage, current, and functional specifications. Wiring safety codes vary by locality, country, or region. The International Electrotechnical Commission (IEC) is attempting to harmonise wiring standards among member countries, but significant variations in design and installation requirements still exist.


Chocolate is a food made from roasted and ground cacao seed kernels that is available as a liquid, solid, or paste, either on its own or as a flavoring agent in other foods. Cacao has been consumed in some form since at least the Olmec civilization (19th-11th century BCE), and the majority of Mesoamerican people ─ including the Maya and Aztecs ─ made chocolate beverages.The seeds of the cacao tree have an intense bitter taste and must be fermented to develop the flavor. After fermentation, the seeds are dried, cleaned, and roasted. The shell is removed to produce cocoa nibs, which are then ground to cocoa mass, unadulterated chocolate in rough form. Once the cocoa mass is liquefied by heating, it is called chocolate liquor. The liquor may also be cooled and processed into its two components: cocoa solids and cocoa butter. Baking chocolate, also called bitter chocolate, contains cocoa solids and cocoa butter in varying proportions, without any added sugar. Powdered baking cocoa, which contains more fiber than cocoa butter, can be processed with alkali to produce dutch cocoa. Much of the chocolate consumed today is in the form of sweet chocolate, a combination of cocoa solids, cocoa butter or added vegetable oils, and sugar. Milk chocolate is sweet chocolate that additionally contains milk powder or condensed milk. White chocolate contains cocoa butter, sugar, and milk, but no cocoa solids.Chocolate is one of the most popular food types and flavors in the world, and many foodstuffs involving chocolate exist, particularly desserts, including cakes, pudding, mousse, chocolate brownies, and chocolate chip cookies. Many candies are filled with or coated with sweetened chocolate. Chocolate bars, either made of solid chocolate or other ingredients coated in chocolate, are eaten as snacks. Gifts of chocolate molded into different shapes (such as eggs, hearts, coins) are traditional on certain Western holidays, including Christmas, Easter, Valentine's Day, and Hanukkah. Chocolate is also used in cold and hot beverages, such as chocolate milk and hot chocolate, and in some alcoholic drinks, such as creme de cacao.Although cocoa originated in the Americas, West African countries, particularly Côte d'Ivoire and Ghana, are the leading producers of cocoa in the 21st century, accounting for some 60% of the world cocoa supply.With some two million children involved in the farming of cocoa in West Africa, child slavery and trafficking associated with the cocoa trade remain major concerns. A 2018 report argued that international attempts to improve conditions for children were doomed to failure because of persistent poverty, absence of schools, increasing world cocoa demand, more intensive farming of cocoa, and continued exploitation of child labor.


A cocktail is an alcoholic mixed drink. Most commonly, cocktails are either a combination of spirits, or one or more spirits mixed with other ingredients such as tonic water, fruit juice, flavored syrup, or cream. Cocktails vary widely across regions of the world, and many websites publish both original recipes and their own interpretations of older and more famous cocktails.


Ice is water frozen into a solid state, typically forming at or below temperatures of 0 degrees Celsius or 32 (F) Depending on the presence of impurities such as particles of soil or bubbles of air, it can appear transparent or a more or less opaque bluish-white color.In the Solar System, ice is abundant and occurs naturally from as close to the Sun as Mercury to as far away as the Oort cloud objects. Beyond the Solar System, it occurs as interstellar ice. It is abundant on Earth's surfaceparticularly in the polar regions and above the snow lineand, as a common form of precipitation and deposition, plays a key role in Earth's water cycle and climate. It falls as snowflakes and hail or occurs as frost, icicles or ice spikes and aggregates from snow as glaciers and ice sheets.Ice exhibits at least eighteen phases (packing geometries), depending on temperature and pressure. When water is cooled rapidly (quenching), up to three types of amorphous ice can form depending on its history of pressure and temperature. When cooled slowly, correlated proton tunneling occurs below (, ) giving rise to macroscopic quantum phenomena. Virtually all ice on Earth's surface and in its atmosphere is of a hexagonal crystalline structure denoted as ice Ih (spoken as "ice one h") with minute traces of cubic ice, denoted as ice Ic and, more recently found, Ice VII inclusions in diamonds. The most common phase transition to ice Ih occurs when liquid water is cooled below (, ) at standard atmospheric pressure. It may also be deposited directly by water vapor, as happens in the formation of frost. The transition from ice to water is melting and from ice directly to water vapor is sublimation.Ice is used in a variety of ways, including for cooling, for winter sports, and ice sculpting.


Banana bread is a type of bread made from mashed bananas. It is often a moist and sweet quick bread but some recipes are yeast raised.


A muffin is an individually portioned baked product, however the term can refer to one of two distinct items: a part-raised flatbread (like a crumpet) that is baked and then cooked on a griddle (typically unsweetened), or an (often sweetened) quickbread (like a cupcake) that is chemically leavened and then baked in a mold. While quickbread "American" muffins are often sweetened, there are savory varieties made with ingredients such as corn and cheese, and less sweet varieties like traditional "bran muffins". The flatbread "English" variety is of British or other European derivation, and dates from at least the early 18th century, while the quickbread originated in North America during the 19th century. Both types are common worldwide today.


Spaghetti () is a long, thin, solid, cylindrical pasta. It is a staple food of traditional Italian cuisine. Like other pasta, spaghetti is made of milled wheat and water and sometimes enriched with vitamins and minerals. Italian spaghetti is typically made from durum wheat semolina. Usually the pasta is white because refined flour is used, but whole wheat flour may be added. "Spaghettoni" is a thicker form of spaghetti, while "capellini" is a very thin spaghetti.Originally, spaghetti was notably long, but shorter lengths gained in popularity during the latter half of the 20th century and now it is most commonly available in 25 - 30 (cm) lengths. A variety of pasta dishes are based on it and it is frequently served with tomato sauce or meat or vegetables.


Corn chips are a snack food made from cornmeal fried in oil or baked, usually in the shape of a small noodle or scoop. Corn chips are thick, rigid and very crunchy. Corn chips have the strong aroma and flavor of roasted corn, and are often heavily seasoned with salt.In the United States, Fritos is one of the oldest and most widely recognized brands of corn chips.While corn chips and tortilla chips are both made from corn, the corn in tortilla chips is subjected to the nixtamalization process, resulting in a milder flavor and aroma, and a less rigid texture. Tortilla chips also tend to be larger, thinner, less fatty, and less salty than corn chips. Corn chips are usually eaten alone or with a chip dip. They are a common ingredient in homemade and commercial party mix. In the Southwestern US, a popular dish, Frito pie, is made with corn chips and chili. In some areas, it is popular to pour the chili into a bag of corn chips and eat the mixture directly from the bag.


The leek is a vegetable, a cultivar of "Allium ampeloprasum", the broadleaf wild leek (syn. "Allium porrum"). The edible part of the plant is a bundle of leaf sheaths that is sometimes erroneously called a stem or stalk. The genus "Allium" also contains the onion, garlic, shallot, scallion, chive, and Chinese onion. Three closely related vegetables, elephant garlic, kurrat and Persian leek or "tareh", are also cultivars of "A. ampeloprasum", although different in their uses as food.


Lettuce ("Lactuca sativa") is an annual plant of the family Asteraceae. It is most often grown as a leaf vegetable, but sometimes for its stem and seeds. Lettuce is most often used for salads, although it is also seen in other kinds of food, such as soups, sandwiches and wraps; it can also be grilled. One variety, celtuce (asparagus lettuce), is grown for its stems, which are eaten either raw or cooked. In addition to its main use as a leafy green, it has also gathered religious and medicinal significance over centuries of human consumption. Europe and North America originally dominated the market for lettuce, but by the late 20th century the consumption of lettuce had spread throughout the world. , world production of lettuce and chicory was 27 million tonnes, 56percent of which came from China.Lettuce was originally farmed by the ancient Egyptians, who transformed it from a plant whose seeds were used to obtain oil into an important food crop raised for its succulent leaves and oil-rich seeds. Lettuce spread to the Greeks and Romans; the latter gave it the name , from which the English "lettuce" is derived. By 50 AD, many types were described, and lettuce appeared often in medieval writings, including several herbals. The 16th through 18th centuries saw the development of many varieties in Europe, and by the mid-18th century, cultivars were described that can still be found in modern gardens.Generally grown as a hardy annual, lettuce is easily cultivated, although it requires relatively low temperatures to prevent it from flowering quickly. It can be plagued by numerous nutrient deficiencies, as well as insect and mammal pests, and fungal and bacterial diseases. "L. sativa" crosses easily within the species and with some other species within the genus "Lactuca". Although this trait can be a problem to home gardeners who attempt to save seeds, biologists have used it to broaden the gene pool of cultivated lettuce varieties.Lettuce is a rich source of vitamin K and vitamin A, and a moderate source of folate and iron. Contaminated lettuce is often a source of bacterial, viral, and parasitic outbreaks in humans, including "E. coli" and "Salmonella".


A mango is an edible stone fruit produced by the tropical tree "Mangifera indica". It is believed to have originated in the region between northwestern Myanmar, Bangladesh, and northeastern India. "M. indica" has been cultivated in South and Southeast Asia since ancient times resulting in two types of modern mango cultivars: the "Indian type" and the "Southeast Asian type". Other species in the genus "Mangifera" also produce edible fruits that are also called "mangoes", the majority of which are found in the Malesian ecoregion.Worldwide, there are several hundred cultivars of mango. Depending on the cultivar, mango fruit varies in size, shape, sweetness, skin color, and flesh color which may be pale yellow, gold, green, or orange. Mango is the national fruit of India, Pakistan and the Philippines, while the mango tree is the national tree of Bangladesh.


Macadamia is a genus of four species of trees in the flowering plant family Proteaceae. They are indigenous to Australia, native to northeastern New South Wales and central and southeastern Queensland specifically. Two species of the genus are commercially important for their fruit, the macadamia nut (or simply macadamia). Global production in 2015 was 160000 (t). Other names include Queensland nut, bush nut, maroochi nut, bauple nut and Hawaii nut. In Australian Aboriginal languages, the fruit is known by names such as "bauple", "gyndl" or "jindilli" (north of Great Dividing Range) and "boombera" (south of the Great Range). It was an important source of bushfood for the Aboriginal peoples who are the original inhabitants of the area.The nut was first commercially produced on a wide scale in Hawaii, where Australian seeds were introduced in the 1880s, and for some time they were the world's largest producer. South Africa has been the world's largest producer of the macadamia since the 2010s.


Bird food or bird seed is food (often varieties of seeds, nuts, and/or dried fruits) consumed by wild and domestic birds. While most bird food is fed to commercial fowl (chicken, turkey), people also use bird food to feed their pet birds or provide a feeding site for wild birds.The various types of bird food reflect the species of bird that can be fed, for example, whether they are carnivores, herbivores, insectivores, nectar-eating birds, etc. Bird food can also differ by the feeding strategies employed by beaks in cracking the seed coat and obtaining the seeds inside (hooked versus straight beaks, for example).Sunflower seeds attract the widest variety of birds, and so often form the mainstay backyard bird feeders. However, other varieties of seed can help attract different types of birds to gardens and backyards. In general, mixtures that contain red millet, oats, and other "fillers" are not attractive to most birds, and can lead to a lot of waste as the birds sort through the mix, as well as the potential for fungal and bacterial growth.While popular, bird feeders carry potential risks for the birds that feed there, such as disease, malnutrition, and predation by domestic animals. Researchers recommend that bird feeders be disinfected every time they are refilled.
