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...)

  Overhead stick welding

  
  
  Welding is a fabrication process that joins materials, usually metals or thermoplastics, primarily by using high temperature to melt the parts together and allow them to cool, causing fusion. Common alternative methods include solvent welding (of thermoplastics) using chemicals to melt materials being bonded without heat, and solid-state welding processes which bond without melting, such as pressure, cold welding, and diffusion bonding.
  
  Metal welding is distinct from lower temperature bonding techniques such as brazing and soldering, which do not melt the base metal (parent metal) and instead require flowing a filler metal to solidify their bonds. (Full article...)

  Aza Arnold (October 4, 1788 – 1865) was an American machinist, inventor, millowner, and patent attorney. Born in Smithfield, Rhode Island, he was trained as a machinist during his youth, and in 1809, entered work at Samuel Slater's textile manufacturing equipment plant in Pawtucket. After a failed venture in woolen blanket production and several years of employment at another Pawtucket factory, he invented a device to separate wool during carding and began to experiment with differential gear trains, possibly inventing the device independently or borrowing the concept from contemporary clockmaking.
  
  After building and operating a cotton mill in Great Falls, New Hampshire, he incorporated a differential gear train into a cotton roving frame, allowing the bobbins to progressively slow relative to the spindles, in turn producing higher-quality thread. He patented the gear train in 1823, but was unable to obtain redress for rampant patent infringements, with the technology rapidly spreading across the United States and Europe over the following years. After several years administering a manufacturing plant in North Providence, Rhode Island, he moved to Philadelphia to operate a print works. He moved to Washington, D.C., around 1850 and entered work as a patent attorney. He patented his final invention, a self-raking saw, in June 1856. He died in Washington in 1865, and was buried at a local Quaker cemetery. (Full article...)

  A Skyline train departing Hālawa (Aloha Stadium) station

  
  Skyline is a rapid transit system in the City and County of Honolulu on the island of Oʻahu, in the state of Hawaiʻi. Phase 1 of the project opened June 30, 2023 and lies entirely outside of the Urban Honolulu census-designated place, linking East Kapolei (on the ʻEwa Plain) and Aloha Stadium. Phase 2, connecting to Pearl Harbor and Daniel K. Inouye International Airport before reaching Middle Street, is anticipated to open in late 2025. The final phase, continuing the line across Urban Honolulu to Downtown, is due to open in 2031. Its construction constitutes the largest public works project in Hawaiʻi's history.
  
  The 18.9-mile (30.4 km), automated fixed-guideway line was planned, designed, and constructed by the Honolulu Authority for Rapid Transportation (HART), a semi-autonomous government agency. Hitachi Rail, who also built the railcars used on the line, operates Skyline for the Honolulu Department of Transportation Services (which also manages the region's TheBus service). The almost entirely elevated line is the first large-scale, publicly run metro in the United States to feature platform screen doors and driverless trains. In 2023, the line had a annual ridership of 614,800, or about 3,100 per day as of the third quarter of 2024. (Full article...)

  Station shelter in August 2022

  
  Challis railway station (officially Challis Station) is a suburban railway station in Kelmscott, a suburb of Perth, Western Australia. It is on the Armadale line which is part of the Transperth network, and is 27.3 kilometres (17.0 mi) southwest of Perth station and 3.1 kilometres (1.9 mi) north of Armadale station. The station opened on 29 October 1973, as did the adjacent Sherwood station, filling the large gap between Armadale station and Kelmscott station. It consists of two side platforms with a pedestrian level crossing. It is not fully accessible due to steep ramps and wide gaps at the pedestrian level crossing.
  
  Services are operated by Transperth Train Operations, a division of the state government's Public Transport Authority. Peak services reach seven trains per hour in each direction, whilst off-peak services are four trains per hour. The station is one of the least used ones on the Transperth network, with just 259 boardings per day in October 2017. The City of Armadale rezoned nearby land in the 2010s with the goal of increasing patronage. (Full article...)

  New York State Route 350 (NY 350) is a north–south state highway in western Wayne County, New York, in the United States. It extends for 11.40 miles (18.35 km) from an intersection with NY 31 and NY 31F in the village of Macedon to a junction with NY 104 in the town of Ontario. NY 350 serves as the eastern terminus for three routes: the aforementioned NY 31F, NY 286, and NY 441, all of which originate in the Rochester area. Aside from the village of Macedon at its south end and the hamlet of Ontario Center at its north terminus, NY 350 serves mostly rural areas dominated by farmland. NY 350 was assigned c. 1932 to the portion of its routing south of Cator Corners, the north junction with NY 31F. It was extended northward to its current terminus in the 1940s. (Full article...)

  An 18th-century Dutch hoeker

  
  Meermin (Dutch pronunciation: [ˈmeːrmɪn] ^ⓘ) was an 18th-century Dutch cargo ship of the hoeker type, one of many built and owned by the Dutch East India Company. She was laid down in 1759 and fitted out as a slave ship before her maiden voyage in 1761, and her career was cut short by a mutiny of her cargo of Malagasy people. They had been sold to Dutch East India Company officials on Madagascar, to be used as company slaves in its Cape Colony in southern Africa. Half her crew and almost 30 Malagasy lost their lives in the mutiny; the mutineers deliberately allowed the ship to drift aground off Struisbaai, now in South Africa, in March 1766, and she broke up in situ. As of 2013, archaeologists are searching for the Meermin's remains. (Full article...)

  Mary 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.

  Thomas Edison (1847–1931) was an American inventor, scientist and businessman who developed many devices that greatly influenced life around the world, including the phonograph, the motion picture camera, and a long-lasting, practical electric light bulb. Dubbed "The Wizard of Menlo Park" (now Edison, New Jersey) by a newspaper reporter, he was one of the first inventors to apply the principles of mass production and large teamwork to the process of invention, and therefore is often credited with the creation of the first industrial research laboratory. Edison is considered one of the most prolific inventors in history, holding 1,093 U.S. patents in his name, as well as many patents in the United Kingdom, France and Germany.

  Pitstone Windmill, believed to be the oldest windmill in the British Isles
  
  A windmill is an engine powered by wind energy. In Europe, windmills have been used since the Middle Ages. They were developed from the 12th century, apparently from technology gained by crusaders who came into contact with windmills in the Middle East. Persian sources indicate windmill use as early as the 7th century BC. In the United States, the development of water-pumping windmills was a major factor in allowing the farming of vast areas of North America.
