The wheel, invented sometime before the 4th millennium BC, is one of the most ubiquitous and important technologies. This detail of the "Standard of Ur", c. 2500 BCE., displays a Sumerian chariot

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 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 prehistory, followed by the control of fire—which in turn contributed to the growth of the human brain and the development of language during the Ice Age, according to the cooking hypothesis. 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...)

  K-19 is a 33.915-mile-long (54.581 km) state highway in the U.S. state of Kansas. From U.S. Route 50 (US-50) to K-19 Spur it is signed as north–south and from K-19 Spur to US-281 it is signed as east–west. K-19's southern terminus is at US-50 in Belpre, and the eastern terminus is at US-281 east of Seward.
  
  Before state highways were numbered in Kansas, there were auto trails. The southern terminus follows the former New Santa Fe Trail. The northern terminus of K-19 Spur follows the former National Old Trails Road and Old Santa Fe Trail. K-19 was first designated in 1926, and at that time started in Belpre and ended in Larned. Then between 1931 and 1932, K-19 was extended east, from south of Larned, along the former K-37 designation to K-8, now US-281. (Full article...)

  A CSX Transportation freight train in Cordele, Georgia on the former Waycross Air Line Railroad mainline

  
  The Waycross Air Line Railroad, chartered in 1887, was an air-line railroad in Georgia. It began operations between Waycross and Sessoms in 1890. In 1901, the railroad had extended as far as Fitzgerald, Georgia, at which time its charter was amended for an extension to Birmingham, Alabama, and it was renamed the Atlantic and Birmingham Railroad. That company purchased the Tifton and Northeastern Railroad and Tifton, Thomasville and Gulf Railway on December 3, 1903, changing its name to the Atlantic and Birmingham Railway. In 1906, the Atlantic and Birmingham Railway was in turn purchased by the Atlanta, Birmingham and Atlantic Railway, which continued expansion towards Birmingham.
  
  The Atlanta, Birmingham and Atlantic Railway changed hands again in 1926, becoming the Atlanta, Birmingham and Coast Railroad, a subsidiary of the Atlantic Coast Line Railroad. The original Waycross Air Line Railroad main line survived the 1967 ACL and SAL merger into the Seaboard Coast Line Railroad, the acquisition of the Family Lines (CRR, L&N, GA, AWP) into the Seaboard System Railroad in 1982 and finally absorption into the Chessie System to become part of CSX in 1987. As of 2022, it remains in service as an important CSX Transportation line, known as the Fitzgerald Subdivision. (Full article...)

  The abandoned station canopy viewed in October 2020.

  
  The Richmond Hill station is a closed station on the Montauk Branch of the Long Island Rail Road in the Richmond Hill neighborhood of Queens in New York City. The station is located at Myrtle Avenue and cuts diagonally from the intersection of Jamaica Avenue and Lefferts Boulevard through to Hillside Avenue. The station has two tracks and an island platform. Richmond Hill was the only station on the Lower Montauk Branch that was elevated with a high-level platform for passengers to wait for trains; the others were at ground level, with low-level platforms.
  
  The Richmond Hill station was originally built by the South Side Railroad of Long Island in 1869 as the Clarenceville station. After New York City and the Long Island Rail Road began negotiating the elimination of numerous at-grade crossings within Queens in the 1910s, the current station was opened on a viaduct in 1923. The station was closed on March 16, 1998, along with nine others due to low ridership and the potential cost of upgrading the stations to modern standards; at the time of its closure, the station averaged one passenger per day.

  Route 57 is a state highway located in Warren County in the U.S. state of New Jersey. It runs 21.10 mi (33.96 km) from an interchange with U.S. Route 22 (US 22) in Lopatcong Township to an intersection with Route 182 and County Route 517 (CR 517) in Hackettstown. The route passes through mostly rural areas of farmland and mountains in Warren County. It also passes through Washington, where Route 57 crosses Route 31. The route is designated a scenic byway, the Warren Heritage Scenic Byway, by the state of New Jersey due to the physical environments it passes through as well as from historical sites along the way such as the Morris Canal.
  
  The current alignment of Route 57 was designated as a part of pre-1927 Route 12 in 1917. In 1927, Route 24 was designated along this route between the Phillipsburg area and Penwell in Mansfield Township while a spur of Route 24 called Route S24 replaced pre-1927 Route 12 between Penwell and US 46 in Hackettstown. When New Jersey renumbered its state highways in 1953, the portion of Route S24 between Penwell and CR 517 in Hackettstown became a part of Route 24 to complete a gap in that route while Route S24 north of there became Route 57. A never-built segment of Route 57 running from the intersection of Route 24 and Route 57 to US 46 east of Hackettstown was legislated in 1965. Around 1970, Route 57 was designated along Route 24 west of Hackettstown while the portion of Route 57 in Hackettstown became Route 182. (Full article...)

  New York State Route 108 (NY 108) is a 1.72-mile-long (2.77 km) north–south state highway located on the Suffolk County side of the Suffolk–Nassau county line on Long Island, New York, in the United States. It is a spur route connecting NY 25A in Cold Spring Harbor to the Cold Spring Harbor station on the Long Island Rail Road's Port Jefferson Branch via Harbor Road. Harbor Road terminates at an intersection with Woodbury Road, on the Nassau County line, which carries County Route 11 to the east and unsigned County Route 12 to the west. NY 108, assigned in the early 1930s, is the shortest state highway on Long Island. (Full article...)

  I-37 from the top of the Tower of the Americas in San Antonio

  
  Interstate 37 (I-37) is a 143-mile (230 km) Interstate Highway located within the southern portion of the US state of Texas. The highway was first designated in 1959 as a route between Corpus Christi and San Antonio. Construction in the urban areas of Corpus Christi and San Antonio began in the 1960s, and the segments of the Interstate Highway in rural areas were completed by the 1980s. Prior to I-37, the route between Corpus Christi and San Antonio was served by a combination of State Highway 9 (SH 9) from Corpus Christi to Three Rivers and US Highway 281 (US 281) from Three Rivers to San Antonio. As a result of the construction of I-37, SH 9 was removed from the State Highway System (the designation would be reinstated to another highway in 2014).
  
  The highway begins in Corpus Christi at US 181 and SH 35 and heads north to San Antonio, where it ends at I-35. Beyond I-35, the freeway continues as US 281 to northern San Antonio as a major freeway. In Corpus Christi, the highway provides access to the downtown area, the Port of Corpus Christi, and Corpus Christi International Airport. In San Antonio, it provides access to Downtown San Antonio, Brooks City-Base, the Alamodome, the Tower of the Americas, the San Antonio River Walk, the Alamo, and, by extension via US 281, San Antonio International Airport. The route provides an important connection between I-35 and the Texas Gulf Coast as well as one of the few limited-access hurricane evacuation routes away from the southern Texas coast.

  George Washington Carver

  Photograph credit: Unknown; restored by Adam Cuerden

  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 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.
