Technology is the application of conceptual knowledge to achieve practical goals, especially in a reproducible way. The word technology can also mean the products resulting from such efforts, including both tangible tools such as utensilsormachines, and intangible ones such as software. Technology plays a critical role in science, engineering, and everyday life.
Technological advancements have led to significant changes in society. The earliest known technology is the stone tool, used during prehistoric times, followed by the control of fire, which contributed to the growth of the human brain and the development of language during the Ice Age. The invention of the wheel in the Bronze Age allowed greater travel and the creation of more complex machines. More recent technological inventions, including the printing press, telephone, and the Internet, have lowered barriers to communication and ushered in the knowledge economy. (Full article...)

King's Highway 114, commonly referred to as Highway 114, was a provincially maintained highway in the Canadian province of Ontario. It was one of the shortest highways ever assigned in the province, at just 1.8 kilometres (1.1 mi) in length. The route followed Malden Road for its entire length between Highway 3 and Highway 98. Part of the original provincial highway network created in 1920, Highway 114 was created in 1953 out of a route renumbering. Prior to 1953, it had been numbered Highway 2A from 1929 until 1931, Highway 3A from 1931 until 1938, and Highway 98A from 1938 until 1953. Today, Malden Road is an unnumbered local road.

The Niagara Parkway, formerly known as Niagara Boulevard and historically as the Niagara Road, is a scenic road in the province of Ontario that travels on the Canadian side of the Niagara River from the town of Fort ErietoNiagara-on-the-Lake. The portion north of Table Rock in the city of Niagara Falls is designated as an Ontario Scenic Highway. Niagara Boulevard originally referred only to the section from Fort Erie to Chippawa.
The Niagara Parkway begins at Fort Erie in the south. It passes through several villages along the river before passing through the tourist district of Niagara Falls. North of the city it provides access to several attractions, including the Whirlpool Rapids, Butterfly Conservatory, and Brock's Monument at Queenston Heights. The route ends at Fort George, southeast of the urban centre of Niagara-on-the-Lake. (Full article...)
State Route 174 (SR 174) is a state highway in the U.S. stateofCalifornia. The two-lane 13-mile (21 km) highway in the western Sierra Nevada, added to the state highway system in 1933, connects Interstate 80inColfax with SR 20/SR 49inGrass Valley, crossing the Bear River next to a 1924 concrete arch bridge. The majority of the route is eligible for the State Scenic Highway System, but local residents have blocked its designation due to property right concerns. (Full article...)
King's Highway 406 (pronounced "four-oh-six"), commonly referred to as Highway 406, is a 400-series highway in the Canadian provinceofOntario. The primary north–south route through the central portion of the Niagara Peninsula, Highway 406 connects Welland, Thorold and downtown St. Catharines to the Queen Elizabeth Way (QEW).
Construction of Highway 406 began in 1963. The first section opened between St. Davids Road and Geneva Street on December 7, 1965, followed by a southward extension to Beaverdams Road in late 1969. The route was later extended south as a super two to Merritt Road where it became Highway 58. In 1977, construction began to connect the freeway with the QEW; this was completed in late 1984. Construction on the route resumed in 1987, connecting the route with East Main Street in Welland, completed in 1995.
In 2009 construction resumed on the highway to expand the remaining two-lane sections to a four-lane divided freeway, with the existing route becoming the southbound lanes of the new freeway. The southern terminus in Welland was converted to a roundabout while the remaining at-grade intersections were rebuilt as interchanges. (Full article...)
Route 208 is a state highway in the northern part of New Jersey in the United States. It runs 10.07 miles (16.21 km) from an interchange with Route 4 and County Route 79 (CR 79, Saddle River Road) in Fair Lawn northwest to an interchange with Interstate 287 (I-287) in Oakland. The route runs through suburban areas of Bergen and Passaic counties as a four- to six-lane divided highway. The route runs through the communities of Fair Lawn, Glen Rock, Hawthorne, Wyckoff, and Franklin Lakes along the way, interchanging with CR 507 in Fair Lawn and CR 502 in Franklin Lakes.
What is now Route 208 was initially planned as Route S4B in 1929, a spur of Route 4 that was to run from Fair Lawn northwest to the New York border in Greenwood Lake, where it would eventually connect to New York State Route 208 (NY 208). This route replaced what was planned as a part of Route 3 in 1927 between Paterson and Greenwood Lake. By the time the route was renumbered to Route 208 in 1953 to match NY 208, only a portion of the route in Fair Lawn from Route 4 to Maple Avenue had been built. Route 208 was completed west to U.S. Route 202 (US 202) in Oakland by 1960 as a two-lane undivided road; it would be built into its present configuration in later years. A Route 208 freeway was planned across the Ramapo Mountains from Oakland to connect to a proposed NY 208 freeway at Greenwood Lake; however, it was never built. After I-287 was extended from Montville to the New York border in 1993, it took over the alignment of Route 208 between US 202 and the route’s current northern terminus. The last traffic signal along Route 208 at McBride Avenue was removed in 1995 and the interchange with Route 4 and Saddle River Road was reconstructed in 2002. (Full article...)
Interstate 87 (I-87) is a 333.49-mile-long (536.70 km) north–south Interstate Highway located entirely within the US state of New York. I-87 is the main highway that connects New York City and Montreal. The highway begins at exit 47 off I-278 in the New York City borough of the Bronx, just north of the Robert F. Kennedy Bridge and Grand Central Parkway. From there, the route runs northward through the Hudson Valley, the Capital District, and the easternmost part of the North Country to the Canada–United States border in the town of Champlain. At its north end, I-87 continues into QuebecasAutoroute 15 (A-15). I-87 connects with several regionally important roads: I-95 in New York City, New York State Route 17 (NY 17; future I-86) near Harriman, I-84 near Newburgh, and I-90inAlbany. The highway is not contiguous with I-87inNorth Carolina.
I-87 was assigned in 1957 as part of the establishment of the Interstate Highway System. The portion of I-87 south of Albany follows two controlled-access highways that predate the Interstate Highway designation, the Major Deegan Expressway (locally known as "the Deegan") in New York City and the tolled New York State Thruway from the New York City line to Albany. North of Albany, I-87 follows the Adirondack Northway, a highway built in stages between 1957 and 1967 (finished just in time to bring Americans to the World Exhibition held in Montreal that year). Early proposals for I-87 called for the route to take a more easterly course through the Hudson Valley and extreme southwestern Connecticut between New York City and Newburgh. These plans were scrapped in 1970 when I-87 was realigned onto the Thruway between Westchester County and Newburgh. (Full article...)
The Mark IV tank was introduced by the British in May 1917 to fight in World War I. The "female" version, as pictured here, was armed with five machine guns. Production of the Mark IV ceased at the end of the War in 1918. A small number served briefly with other combatants afterwards.
This Mark IV tank, on display in Ashford, Kent, was presented to the town after the end of World War I. The engine was removed to install an electricity substation inside it, though this substation was subsequently removed; the tank's interior is now empty.
A portrait of George Washington Carver, American scientist, botanist, educator and inventor, from 1942. Much of Carver's fame is based on his research into and promotion of alternative cropstocotton, such as peanuts and sweet potatoes. In addition to his work on agricultural extension education for purposes of advocacy of sustainable agriculture and appreciation of plants and nature, Carver's important accomplishments also included improvement of racial relations, mentoring children, poetry, painting, and religion. One of his most important roles was in undermining, through the fame of his achievements and many talents, the widespread stereotype of the time that the black race was intellectually inferior to the white race.

Amultiple exposure composite image of the implosion of a chimney at the former brewery "Henninger" in Frankfurt am Main, Germany. This controlled demolition technique involves strategically placing explosive material and timing its detonation so that a structure collapses on itself in a matter of seconds, minimizing the physical damage to its immediate surroundings.
George Washington Carver (1860s–1943) was an American agricultural scientist and inventor. Born into slavery in Diamond, Missouri, he was raised by his master Moses Carver after being emancipated, having been separated from his parents as an infant during a kidnapping incident. After college, Carver became a professor at Tuskegee Institute, where he developed techniques to improve soils depleted by repeated plantings of cotton. He wanted poor farmers to grow alternative crops, such as peanuts and sweet potatoes, as a source of their own food and to improve their quality of life. Carver spent years developing and promoting products made from peanuts, although none became commercially successful. Apart from his work to improve the lives of farmers, he was also a leader in promoting environmentalism. Carver received numerous honors for his work, including the NAACP's Spingarn Medal. In an era of very high racial polarization, his fame reached beyond the black community; he was widely recognized and praised in the white community for his many achievements and talents. In 1941, Time magazine dubbed Carver a "black Leonardo".
This picture of Carver was taken around 1910 and is in the collection of the Tuskegee University archives.
The rotor of a modern steam turbine , which converts steam (heat) energy into kinetic (mechanical) energy. The steam path is from the smallest blade, expanding through progressively larger blade elements. Steam turbines are used in power plants to extract mechanical work from pressurized steam and benefit from their high efficiency and high power-to-weight ratio compared to other technologies, leading to their widespread deployment from electricity generation to marine propulsion.

The garage, which could originally hold 200 buses, has been a Grade II* Listed Building since 1988.
The William Crooks is a 4-4-0 steam locomotive that was the first locomotive to operate in the U.S. state of Minnesota, beginning in 1861. It was named after William Crooks, the chief mechanical engineer for the St. Paul and Pacific Railroad, who earlier served as a colonel in the 6th Minnesota Volunteer Infantry Regiment during the American Civil War. Crooks laid out the initial ten-mile track between Minneapolis and St. Paul on which the locomotive operated. It was retired from regular service in 1897, but operated special services for several further decades. It is now in the Lake Superior Railroad Museum in Duluth.
The four-stroke cycle of an internal combustion engine is the cycle most commonly used for automotive and industrial purposes today, including cars, trucks, and generators.
The cycle was invented by Nikolaus Ottoin1876, and is also called the Otto cycle. The cycle is characterized by four strokes, or straight movements in a single direction, of the piston.
Afilling stationinSabah, Malaysia, operated by Royal Dutch Shell. Filling stations, also known under a wide variety of names, are facilities that sell fuel and engine lubricants for motor vehicles. They include one or more fuel dispensers, which distribute fuels such as gasoline and diesel into the tanks within vehicles and calculate the financial cost of the fuel transferred. Filling stations may also include air compressors and electricity sockets, which may inflate tyres or offer charging stations. Many filling stations also incorporate a convenience store, where customers can purchase snacks and other goods.
The Australia Telescope Compact Array is a radio telescope operated by the Commonwealth Scientific and Industrial Research Organisation (CSIRO) at the Paul Wild Observatory, 25 km (16 mi) west of the town of NarrabriinNew South Wales, Australia. The telescope is an array of six identical dishes each 22 metres (72 ft) in diameter, which commonly operate in aperture synthesis mode to produce images from radio waves. Five of the dishes can be moved along a 3-kilometre (2 mi) railway track; the sixth is situated three kilometres west of the end of the main track. Each dish weighs about 270 tonnes (270 long tons; 300 short tons).
This photograph, showing five of the Australia Telescope Compact Array's dishes, was taken around 1984, in the late phase of the construction process. It is a long-exposure photograph taken in darkness in the late evening; during the exposure, the photographer, John Masterson, walked around the dishes firing off over 130 flashes using a hand-held flash gun.
Bucket-wheel excavators (BWEs) are heavy equipment used in surface mining. The primary function of a BWE is to act as a continuous digging machine in large-scale open pit mining operations. These BWEs were photographed at the Garzweiler surface mine in Germany.
