Technological And Industrial History Of Canada
The technological and industrial history of Canada encompasses the country's development in the areas of transportation, communication, energy, materials, public works, public services (health care), domestic/consumer and defense technologies. Most technologies diffused in Canada came from other places; only a small number actually originated in Canada. For more about those with a Canadian origin, see Invention in Canada. The terms chosen for the "age" described below are both literal and metaphorical. They describe the technology that dominated the period in question but are also representative of a large number of other technologies introduced during the same period. Also of note is the fact that the period of diffusion of a technology can begin modestly and can extend well beyond the "age" of its introduction. To maintain continuity, the treatment of its diffusion is dealt with in the context of its dominant "age". For example, the "Steam Age" here is defined as being from 1840 ...

Transportation
Transport (in British English), or transportation (in American English), is the intentional movement of humans, animals, and goods from one location to another. Modes of transport include air, land (rail and road), water, cable, pipeline, and space. The field can be divided into infrastructure, vehicles, and operations. Transport enables human trade, which is essential for the development of civilizations. Transport infrastructure consists of both fixed installations, including roads, railways, airways, waterways, canals, and pipelines, and terminals such as airports, railway stations, bus stations, warehouses, trucking terminals, refueling depots (including fueling docks and fuel stations), and seaports. Terminals may be used both for interchange of passengers and cargo and for maintenance. Means of transport are any of the different kinds of transport facilities used to carry people or cargo. They may include vehicles, riding animals, and pack animals. Vehicl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Igloo
An igloo (Inuit languages: , Inuktitut syllabics (plural: )), also known as a snow house or snow hut, is a type of shelter built of suitable snow. Although igloos are often associated with all Inuit, they were traditionally used only by the people of Canada's Central Arctic and the Qaanaaq area of Greenland. Other Inuit tended to use snow to insulate their houses, which were constructed from whalebone and hides. Snow is used because the air pockets trapped in it make it an insulator. On the outside, temperatures may be as low as , but on the inside, the temperature may range from when warmed by body heat alone. Nomenclature The Inuit language word (plural ) can be used for a house or home built of any material, and is not restricted exclusively to snowhouses (called specifically , plural ), but includes traditional tents, sod houses, homes constructed of driftwood and modern buildings. Several dialects throughout the Canadian Arctic (Siglitun, Inuinnaqtun, Natsil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tomahawk (axe)
A tomahawk is a type of single-handed axe used by the many Indigenous peoples and nations of North America. It traditionally resembles a hatchet with a straight shaft. In pre-colonial times the head was made of stone, bone, or antler, and European settlers later introduced heads of iron and steel. The term came into the English language in the 17th century as an adaptation of the Powhatan (Virginian Algonquian) word. Tomahawks were general-purpose tools used by Native Americans and later the European colonials with whom they traded, and often employed as a hand-to-hand weapon. The metal tomahawk heads were originally based on a Royal Navybr>boarding axe(a lightweight hand axe designed to cut through boarding nets when boarding hostile ships) and used as a trade-item with Native Americans for food and other provisions. Etymology The name comes from Powhatan , derived from the Proto-Algonquian root 'to cut off by tool'. Algonquian cognates include Lenape , Malecite-Passamaq ...

Bow And Arrow
The bow and arrow is a ranged weapon system consisting of an elastic launching device (bow) and long-shafted projectiles ( arrows). Humans used bows and arrows for hunting and aggression long before recorded history, and the practice was common to many prehistoric cultures. They were important weapons of war from ancient history until the early modern period, where they were rendered increasingly obsolete by the development of the more powerful and accurate firearms. Today, bows and arrows are mostly used for hunting and sports. Archery is the art, practice, or skill of using bows to shoot arrows.Paterson ''Encyclopaedia of Archery'' p. 17 A person who shoots arrows with a bow is called a bowman or an archer. Someone who makes bows is known as a bowyer,Paterson ''Encyclopaedia of Archery'' p. 31 someone who makes arrows is a fletcher,Paterson ''Encyclopaedia of Archery'' p. 56 and someone who manufactures metal arrowheads is an arrowsmith.Paterson ''Encyclopaedia of Arche ...

Scurvy
Scurvy is a disease resulting from a lack of vitamin C (ascorbic acid). Early symptoms of deficiency include weakness, feeling tired and sore arms and legs. Without treatment, decreased red blood cells, gum disease, changes to hair, and bleeding from the skin may occur. As scurvy worsens there can be poor wound healing, personality changes, and finally death from infection or bleeding. It takes at least a month of little to no vitamin C in the diet before symptoms occur. In modern times, scurvy occurs most commonly in people with mental disorders, unusual eating habits, alcoholism, and older people who live alone. Other risk factors include intestinal malabsorption and dialysis. While many animals produce their own vitamin C, humans and a few others do not. Vitamin C is required to make the building blocks for collagen. Diagnosis is typically based on physical signs, X-rays, and improvement after treatment. Treatment is with vitamin C supplements taken by mouth. Improvemen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agriculture
Agriculture or farming is the practice of cultivating plants and livestock. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in cities. The history of agriculture began thousands of years ago. After gathering wild grains beginning at least 105,000 years ago, nascent farmers began to plant them around 11,500 years ago. Sheep, goats, pigs and cattle were domesticated over 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. Industrial agriculture based on large-scale monoculture in the twentieth century came to dominate agricultural output, though about 2 billion people still depended on subsistence agriculture. The major agricultural products can be broadly grouped into foods, fibers, fuels, and raw materials (such as rubber). Food classes include cereals (grains), vegetables, fruits, cooking oils, meat, milk, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pemmican
Pemmican (also pemican in older sources) is a mixture of tallow, dried meat, and sometimes dried berries. A calorie-rich food, it can be used as a key component in prepared meals or eaten raw. Historically, it was an important part of indigenous cuisine in certain parts of North America and it is still prepared today. The word comes from the Cree word (), which is derived from the word (), "fat, grease". The Lakota (or Sioux) word is , originally meaning "grease derived from marrow bones", with the creating a noun, and referring to small pieces that adhere to something. It was invented by the Indigenous peoples of North America. Pemmican was widely adopted as a high-energy food by Europeans involved in the fur trade and later by Arctic and Antarctic explorers, such as Captain Robert Bartlett, Ernest Shackleton, Richard E. Byrd, Fridtjof Nansen, Robert Falcon Scott, George W. DeLong, and Roald Amundsen. Ingredients Traditionally, the specific ingredients used for pemmican w ...

Kayak
A kayak is a small, narrow watercraft which is typically propelled by means of a double-bladed paddle. The word kayak originates from the Greenlandic word ''qajaq'' (). The traditional kayak has a covered deck and one or more cockpits, each seating one paddler. The cockpit is sometimes covered by a spray deck that prevents the entry of water from waves or spray, differentiating the craft from a canoe. The spray deck makes it possible for suitably skilled kayakers to roll the kayak: that is, to capsize and right it without it filling with water or ejecting the paddler. ] Some modern boats vary considerably from a traditional design but still claim the title "kayak", for instance in eliminating the cockpit by seating the paddler on top of the boat ("sit-on-top" kayaks); having inflated air chambers surrounding the boat; replacing the single hull with twin hulls; and replacing paddles with other human-powered propulsion methods, such as foot-powered rotational propellers and "fli ...

Dog Team
A sled dog is a dog trained and used to pull a land vehicle in Dog harness, harness, most commonly a Dog sled, sled over snow. Sled dogs have been used in the Arctic for at least 8,000 years and, along with watercraft, were the only transportation in Arctic areas until the introduction of semi-trailer trucks, snowmobiles and airplanes in the 20th century, hauling supplies in areas that were inaccessible by other methods. They were used with varying success in the explorations of both Geographical pole, poles, as well as during the Yukon Gold Rush, Alaskan gold rush. Sled dog teams delivered mail to rural communities in Alaska, Yukon, Northwest Territories and Nunavut. Sled dogs today are still used by some rural communities, especially in areas of Russia, Canada, and Alaska as well as much of Greenland. They are used for recreational purposes and dog sled racing, racing events, such as the Iditarod Trail Sled Dog Race, Iditarod Trail and the Yukon Quest. History Sled dogs ar ...

Snow Shoe
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. Development Origins Before people built ...

Travois
A travois (; Canadian French, from French , a frame for restraining horses; also obsolete travoy or travoise) is a historical frame structure that was used by indigenous peoples, notably the Plains Aboriginals of North America, to drag loads over land. There is evidence to support the thesis that travois were used in other parts of the world before the invention of the wheel. Construction and use The basic construction consists of a platform or netting mounted on two long poles, lashed in the shape of an elongated isosceles triangle; the frame was dragged with the sharply pointed end forward. Sometimes the blunt end of the frame was stabilized by a third pole bound across the two poles. The travois was dragged by hand, sometimes fitted with a shoulder harness for more efficient dragging, or dragged by dogs or horses (after the 16th-century introduction of horses by the Spanish). A travois could either be loaded by piling goods atop the bare frame and tying them in place, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dugout (boat)
A dugout canoe or simply dugout is a boat made from a hollowed tree. Other names for this type of boat are logboat and monoxylon. ''Monoxylon'' (''μονόξυλον'') (pl: ''monoxyla'') is Greek – ''mono-'' (single) + '' ξύλον xylon'' (tree) – and is mostly used in classic Greek texts. In German, they are called Einbaum ("one tree" in English). Some, but not all, pirogues are also constructed in this manner. Dugouts are the oldest boat type archaeologists have found, dating back about 8,000 years to the Neolithic Stone Age. This is probably because they are made of massive pieces of wood, which tend to preserve better than others, such as bark canoes. Along with bark canoes and hide kayaks, dugouts were also used by Indigenous peoples of the Americas. Construction Construction of a dugout begins with the selection of a log of suitable dimensions. Sufficient wood must be removed to make the vessel relatively light in weight and buoyant, yet still strong enough to su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
