Technology is the application of conceptual knowledge for achieving 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 utensils or machines, 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...)

Image 1King's Highway 33, commonly referred to as Highway 33 or Loyalist Parkway, is a provincially maintained highway in the Canadian province of Ontario. The route begins at Highway 62 in Bloomfield and travels east to the Collins Bay Road junction at Collins Bay in the city of Kingston, a distance of 60.9 kilometres (37.8 mi). The highway continues farther east into Kingston as Bath Road (Kingston Road 33), ending at the former Highway 2, now Princess Street. Highway 33 is divided into two sections by the Bay of Quinte. The Glenora Ferry service crosses between the two sections just east of Picton, transporting vehicles and pedestrians for free throughout the year.
Originally, Highway 33 continued northeast through Trenton to the town of Stirling, ending at a junction with Highway 14. This section was transferred to county governments by the beginning of 1998. In 2009, Highway 33 west of Picton became the site of the first modern roundabout on a provincial highway. (Full article...) -

Injection moulding (U.S. spelling: injection molding) is a manufacturing process for producing parts by injecting molten material into a mould, or mold. Injection moulding can be performed with a host of materials mainly including metals (for which the process is called die-casting), glasses, elastomers, confections, and most commonly thermoplastic and thermosetting polymers. Material for the part is fed into a heated barrel, mixed (using a helical screw), and injected into a mould cavity, where it cools and hardens to the configuration of the cavity. After a product is designed, usually by an industrial designer or an engineer, moulds are made by a mould-maker (or toolmaker) from metal, usually either steel or aluminium, and precision-machined to form the features of the desired part. Injection moulding is widely used for manufacturing a variety of parts, from the smallest components to entire body panels of cars. Advances in 3D printing technology, using photopolymers that do not melt during the injection moulding of some lower-temperature thermoplastics, can be used for some simple injection moulds.
Injection moulding uses a special-purpose machine that has three parts: the injection unit, the mould and the clamp. Parts to be injection-moulded must be very carefully designed to facilitate the moulding process; the material used for the part, the desired shape and features of the part, the material of the mould, and the properties of the moulding machine must all be taken into account. The versatility of injection moulding is facilitated by this breadth of design considerations and possibilities. (Full article...) -
Image 3U.S. Route 46 (US 46) is an east–west U.S. Highway completely within the state of New Jersey, running for 75.34 mi (121.25 km), making it the shortest signed, non-spur U.S. Highway. The west end is at an interchange with Interstate 80 (I-80) and Route 94 in Columbia, Warren County, on the Delaware River. The east end is in the middle of the George Washington Bridge over the Hudson River in Fort Lee, Bergen County, while the route is concurrent with I-95 and US 1-9. Throughout much of its length, US 46 is closely paralleled by I-80. US 46 is a major local and suburban route, with some sections built to or near freeway standards and many other sections arterials with jughandles. The route runs through several communities in the northern part of New Jersey, including Hackettstown, Netcong, Dover, Parsippany-Troy Hills, Wayne, Clifton, Ridgefield Park, Palisades Park, and Fort Lee. It crosses over the Upper Passaic River at several points. The road has been ceremonially named the United Spanish–American War Veterans Memorial Highway.
What is now US 46 was originally designated as three separate routes. Pre-1927 Route 5 was created in 1916 to follow the road from Delaware to Denville, pre-1927 Route 12 in 1917 to follow the route between Hackettstown and Paterson, and pre-1927 Route 10 in 1917 to run between Paterson and Edgewater. In 1927, Route 6 was legislated to run from Delaware east to the George Washington Bridge, replacing portions of Routes 5 and 12 and paralleling the former Route 10, which itself became Route 5 and Route 10N, the latter being shortly removed from the state highway system. In 1936, US 46 was designated to run from US 611 in Portland, Pennsylvania, east to the George Washington Bridge. The route replaced Pennsylvania Route 987 (PA 987) to the Delaware Bridge over the Delaware River, and from there followed Route 6 across New Jersey. In 1953, the Route 6 designation was removed from US 46 in New Jersey, and later that year, the route was realigned to end at US 611 in Columbia, New Jersey, replacing a part of Route 94. US 611 had been brought into New Jersey by two new bridges over the Delaware River, following a freeway between them that became a part of I-80. In 1965, US 611 was aligned back into its original Pennsylvania route (which from 1953 until 1965 was US 611 Alternate), and US 46's western terminus remained as an interchange ramp with I-80 and Route 94. Its number is out of place since U.S. Route 46 lies north of U.S. Route 22, U.S. Route 30 and U.S. Route 40. (Full article...) -

Hasvik Airport (Norwegian: Hasvik lufthavn; IATA: HAA, ICAO: ENHK) is a regional airport serving Hasvik Municipality in Finnmark county, Norway. The airport is located in the village of Hasvik on the island of Sørøya. In 2012, Hasvik Airport had 7,629 passengers, making it the third-least busy airport operated by the state-owned Avinor. The airport consists of a 909-meter (2,982 ft) runway and is served by Widerøe with Dash 8-100 aircraft. The airport tower is operated remotely from Bodø.
Planning started in 1972 for an airport to serve air taxi and air ambulance services. The original 421-meter (1,381 ft) gravel runway opened on 17 May 1973, allowing Norving to operate flights with their Britten-Norman Islanders. The airport was upgraded with a longer runway and a larger terminal in 1983, allowing Norving to start scheduled services to Alta and Hammerfest. Widerøe took over the routes in 1990, at first using the de Havilland Canada Twin Otter. The runway was asphalted in 1995, allowing Widerøe to introduce the Dash 8. The airport was nationalized two years later. (Full article...) -

The London Ringways were a series of four ring roads planned in the 1960s to circle London at various distances from the city centre. They were part of a comprehensive scheme developed by the Greater London Council (GLC) to alleviate traffic congestion on the city's road system by providing high-speed motorway-standard roads within the capital, linking a series of radial roads taking traffic into and out of the city.
There had been plans to construct new roads around London to help traffic since at least the 17th century. Several were built in the early 20th century such as the North Circular Road, Western Avenue and Eastern Avenue, and further plans were put forward in 1937 with The Highway Development Survey, followed by the County of London Plan in 1943. The Ringways originated from these earlier plans, and consisted of the main four ring roads and other developments. Certain sections were upgrades of existing earlier projects such as the North Circular, but much of it was new-build. Construction began on some sections in the 1960s in response to increasing concern about car ownership and traffic. (Full article...) -

Image 7Illinois Route 98 (IL 98, Route 98) is an 8.36-mile (13.45 km) east–west state highway located entirely within Tazewell County in central Illinois. The route runs from Route 29 on the border of Pekin and North Pekin east to Interstate 155 (I-155) in Morton. The highway connects Pekin, North Pekin, Morton, and the community of Groveland; it passes through a variety of landscapes between the towns. Route 98 is maintained by the Illinois Department of Transportation.
The state of Illinois created Route 98 in 1924; the original route connected several cities in western Illinois. The eastern section of this route appeared on maps by 1928, and the highway was completed in 1929. In 1939, Route 98 moved to its current alignment. Its eastern terminus was truncated from downtown Morton to I-155 in the 1990s. (Full article...)

Image 20Photograph credit: Langley Research Center; restored by Adam CuerdenMary Jackson (1921–2005) was an African American mathematician and aerospace engineer at the National Advisory Committee for Aeronautics, which was succeeded by NASA in 1958. For most of her career, she worked at Langley Research Center in Hampton, Virginia; starting as a computer at the segregated West Area Computing division, she later took advanced engineering classes and, in 1958, became NASA's first black female engineer.
After 34 years at NASA, Jackson had earned the most senior engineering title available. Realizing that she could not earn further promotions without becoming a supervisor, she accepted a demotion to become a manager of the Federal Women's Program in the NASA Office of Equal Opportunity Programs, as well as of the Affirmative Action Program. In this role, she worked to influence both the hiring and promotion of women in NASA's science, engineering and mathematics careers. She was portrayed by Janelle Monáe as a lead character in the 2016 film Hidden Figures. This picture, taken in 1980, shows Jackson working at NASA Langley.
