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...)

Alfred Victor Verville (November 16, 1890 – March 10, 1970) was an American aviation pioneer and aircraft designer who contributed to civilian and military aviation. During his forty-seven years in the aviation industry, he was responsible for the design and development of nearly twenty commercial and military airplanes. Verville is known for designing flying boats, military racing airplanes (such as the record breaking Verville-Sperry R-3), and a series of commercial cabin airplanes. His planes were awarded with the Pulitzer Speed Classic Trophy in 1920 and 1924.
Verville was a founder of three aeronautical companies, the General Aeroplane Company, Verville Aircraft Company, and the Buhl Aircraft Company. He worked for General Billy Mitchell during his service at the United States Army Air Service from 1918 to 1925. From 1937 to 1945, he worked as a consultant for companies such as Douglas Aircraft, Curtiss-Wright, Snead Aircraft, and Drexel Aviation. Verville spent the next sixteen years in the U.S. federal government, primarily in the Bureau of Aeronautics, before retiring in 1961. (Full article...) -

The Church Avenue station is an express station on the IND Culver Line of the New York City Subway. Located at Church and McDonald Avenues in Kensington, Brooklyn, it is served by the F and G trains at all times (the latter of which terminates here), and by the <F> train during rush hours in the peak direction.
The Church Avenue station was constructed by the Independent Subway System (IND). It opened on October 7, 1933, as the new terminal of the Culver Line, which was known as the Smith Street Line or the South Brooklyn Line at the time. In 1954, this station ceased to be the line's terminal with the completion of the Culver Ramp, which connected the South Brooklyn Line and the Brooklyn–Manhattan Transit Corporation (BMT)'s Culver Line and allowing service to run to Coney Island. Though the Church Avenue station contains four tracks and two island platforms, as with many express stations in the New York City Subway, the inner tracks see limited use, being used only by peak-direction <F> trains.

Image 3State Route 375 (SR 375) is a 98.414-mile (158.382 km) state highway in Nye and Lincoln counties in south-central Nevada, United States. The highway stretches from State Route 318 at Crystal Springs northwest to U.S. Route 6 (US 6) at Warm Springs. The route travels through mostly unoccupied desert terrain, with much of its alignment paralleling the northern edges of the Nellis Air Force Range. The road originally traversed through what is now the northern reaches of the air force range in the 1930s, when it was previously designated State Route 25A and later part of State Route 25.
The top-secret Area 51 government base is near SR 375, and many travelers have reported UFO observations and other strange alien activity along this road. Such stories prompted the state to officially designate the route as the Extraterrestrial Highway in 1996. The small town of Rachel, located near the midpoint of the highway, caters to tourists, geocachers, and UFO seekers with alien-themed businesses. Although the area receives some tourism due to alleged extraterrestrial activity, SR 375 remains a lightly traveled route. (Full article...) -
Image 4In the C++ programming language,
decltype
is a keyword used to query the type of an expression. Introduced in C++11, its primary intended use is in generic programming, where it is often difficult, or even impossible, to express types that depend on template parameters.
As generic programming techniques became increasingly popular throughout the 1990s, the need for a type-deduction mechanism was recognized. Many compiler vendors implemented their own versions of the operator, typically calledtypeof
, and some portable implementations with limited functionality, based on existing language features were developed. In 2002, Bjarne Stroustrup proposed that a standardized version of the operator be added to the C++ language, and suggested the name "decltype", to reflect that the operator would yield the "declared type" of an expression.

Image 5Interstate 676 (I-676) is an Interstate Highway that serves as a major thoroughfare through Center City Philadelphia, where it is known as the Vine Street Expressway, and Camden, New Jersey, where it is known as the northern segment of the North–South Freeway, as well as the Martin Luther King Jr. Memorial Highway in honor of civil rights leader Martin Luther King Jr. Its western terminus is at I-76 in Philadelphia near the Philadelphia Museum of Art and Fairmount Park. From there, it heads east and is then routed on surface streets near Franklin Square and Independence National Historical Park, home of the Liberty Bell, before crossing the Delaware River on the Benjamin Franklin Bridge. On the New Jersey side of the bridge, the highway heads south to its southern terminus at I-76 in Gloucester City near the Walt Whitman Bridge. Between the western terminus and downtown Camden, I-676 is concurrent with U.S. Route 30 (US 30).
After World War II, freeway approaches were planned for both sides of the Benjamin Franklin Bridge, which was completed in 1926 and serves as a part of US 30. In Pennsylvania, the Vine Street Expressway was planned to run along the northern edge of Center City to the Schuylkill River, while, in New Jersey, the North–South Freeway was to head south along the Route 42 corridor. When the Interstate Highway System was created in the 1950s, this stretch of highway was a part of I-80S, with Interstate 680 (I-680) continuing on the Schuylkill Expressway to the Walt Whitman Bridge.

Amazon HQ2 is Amazon's corporate headquarters in National Landing in Crystal City, Virginia and an expansion of the company's headquarters in Seattle, Washington. Phase I, which has capacity for 14,000 employees, opened in June 2023. Construction on Phase II is delayed and there is no timeline for development.
HQ2 was announced in September 2017, when Amazon submitted request for proposals to governments and economic development organizations asking for tax breaks and other incentives to entice the company. Amazon claimed that it intended to spend $5 billion on construction and that HQ2 would house 50,000 workers when completed. More than 200 cities in Canada, Mexico, and the United States eventually offered tax breaks, expedited construction approvals, promises of infrastructure improvements, new crime-reduction programs, and other incentives. On January 18, 2018, a shortlist of 20 finalists was announced, after which the candidate localities continued to detail or expand their incentive packages. (Full article...) -
Image 7King's Highway 70, commonly referred to as Highway 70, was a provincially maintained highway in the Canadian province of Ontario, which provided a shorter route from Highway 6 and Highway 21 in Springmount to Highway 6 in Hepworth. The route, which now forms part of Highway 6, was 15.1 kilometres (9.4 mi) long and travelled in a southeast–northwest direction west of Owen Sound. The route followed an early trail blazed by deputy surveyor Charles Rankin in 1842 that was upgraded to a modern road in the 1920s. Highway 70 was designated in 1965 and renumbered as Highway 6 in 1997. Another Highway 70 existed near Kenora between 1937 and 1959 before being renumbered as Highway 71. This designation was applied along the newly opened Heenan Highway, shortly after the Department of Highways (DHO) began numbering routes in northern Ontario. However, a series of renumberings in 1960 led to the entire length becoming part of Highway 71. (Full article...)

Image 14Photograph: David GublerThe Wiesen Viaduct is a single-track railway viaduct (concrete blocks with dimension stone coverage) which spans the Landwasser southwest of the hamlet of Wiesen, Switzerland. Designed by Henning Friedrich, then the chief engineer of the Rhaetian Railway, it was built between 1906 and 1909 by the contractor G. Marasi (Westermann & Cie, Zürich) under the supervision of P. Salaz and Hans Studer (RhB). The Rhaetian Railway still owns and uses the viaduct today for regular service with 29 passenger trains per day. An important element of the Davos–Filisur railway, the viaduct is 88.9 metres (292 ft) high, 210 metres (690 ft) long, and has a main span of 55 metres (180 ft). In 1926, the viaduct was the inspiration for Ernst Ludwig Kirchner's painting Brücke bei Wiesen.

Image 19Photo: Arthur Rothstein; Restoration: Lise BroerA 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 crops to cotton, 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.

Image 20Photograph: Peter TrimmingThe 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.
