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 1The Disi Water Conveyance Project is a water supply project in Jordan. It is designed to pump 100,000,000 cubic metres (2.2×1010 imp gal) of water per year from the Disi aquifer, which lies beneath the desert in southern Jordan and northwestern Saudi Arabia. The water is piped to the capital, Amman, and other cities to meet increased demand. Construction began in 2009 and was mostly completed in July 2013 when the project was inaugurated by King Abdullah of Jordan. Its total cost was US$1.1 billion.
An independent study revealed the water to be radioactive and potentially dangerous to drink, initially surrounding the project with controversy. Jordan's Ministry of Water and Irrigation has stated that the radioactivity is not a problem because the water is to be diluted with an equal amount of water from other sources, although it remains disputed if this would be enough to bring the water up to standards. The Ministry said the independent study was inaccurate, as it did not test water from any of the wells that will be used in the project. The President of the Jordanian Geologists Association Bahjat Al Adwan stated that the radiation is present in the water in the form of radon, and thus dissipates harmlessly when the water is exposed to air on the surface.

Waterlooplein is an underground metro station in the city centre of Amsterdam, Netherlands. Served by metro lines 51, 53 and 54 of the Amsterdam Metro, the station was constructed by sinking caissons with a length of 40 metres (130 ft), with the first one being lowered in 1972. There were "open tube" days in 1975 showcasing the station, which was the first time the public got access to the underground tunnels of the metro system.
The station, opened to metro traffic on 11 October 1980, has an island platform of 180 metres (590 ft) and two halls with a total of five entrances. Waterlooplein, along with other stations on the East Line, had a major renovation in 2016 that brought back the brutalist architecture used in the original station. There are two pieces of artwork located in the station: one in a station hall and the other on the platform level. (Full article...) -
Image 3Maryland Route 404 (MD 404) is a major highway on Maryland's Eastern Shore in the United States. Signed east-west, it runs 24.61 miles (39.61 km) from MD 662 in Wye Mills on the border of Queen Anne's and Talbot counties, southeast to the Delaware state line in Caroline County, where the road continues as Delaware Route 404 (DE 404) to the Five Points intersection near Rehoboth Beach. The Maryland and Delaware state highways together cross the width of the Delmarva Peninsula and serve to connect the Baltimore–Washington Metropolitan Area by way of the Chesapeake Bay Bridge and U.S. Route 50 (US 50) with the Delaware Beaches. Along the way, MD 404 passes through mostly farmland and woodland as well as the towns of Queen Anne, Hillsboro, and Denton. The route is a four-lane divided highway between US 50 and east of Denton, with the remainder of the route a two-lane undivided road.
MD 404 was designated by 1933 to run from Matapeake (where the Annapolis–Matapeake ferry across the Chesapeake Bay connected the route to Annapolis), east along present-day MD 8, US 50, and MD 662 to Wye Mills, where it followed its current routing to the Delaware border. By 1946, the route's western terminus was moved to MD 2 north of Annapolis, where it headed east across the Chesapeake Bay on the Sandy Point-Matapeake ferry. The western terminus was cut back to Wye Mills in 1949, having been replaced by US 50 west of there. The route was realigned to bypass Queen Anne and Hillsboro in 1960 and Denton in 1987.

Manchester Liners was a cargo and passenger shipping company founded in 1898, based in Manchester, England. The line pioneered the regular passage of ocean-going ships along the Manchester Ship Canal. Its main sphere of operation was the transatlantic shipping trade, but the company also operated services to the Mediterranean. All of the line's ships were registered in the Port of Manchester, and many were lost to enemy action during the First and Second World Wars.
A successful switch from traditional to container shipping in 1968 was relatively short-lived, as the subsequent introduction elsewhere of much larger container ships meant that the company's ships, which were restricted to a maximum length of 530 feet (160 m) imposed by the ship canal's lock chambers, could no longer compete economically. The line ceased operations in 1985. (Full article...) -

The Kolkata Metro is a rapid transit system serving the city of Kolkata and the wider Kolkata Metropolitan Region in West Bengal, India. Opening in 1984, it was the first operational rapid transit system in India, beside being the second busiest and fourth-longest metro network in India. , it has four operational lines: the 32.13 km (19.96 mi) Line 1 from Dakshineswar to Kavi Subhash, 14.1 km (8.8 mi) Line 2 from Salt Lake Sector V to Howrah Maidan (excluding the under construction section between Sealdah and Esplanade), 7.75 km (4.82 mi) Line 3 from Joka to Majerhat and 5.4 km (3.4 mi) Line 6 from Kavi Subhash to Hemanta Mukherjee for a total of 59.38 km (36.90 mi). Two other lines are in various phases of construction and planning. The system has a mix of underground, at-grade and elevated stations using both broad-gauge and standard-gauge tracks. Trains operate between 06:55 and 22:30 IST and the fares range from ₹5 to ₹50.
The Kolkata Metro was initially planned in the 1920s, but construction started in the 1970s. The first underground stretch, from Bhawanipore (now Netaji Bhawan) to Esplanade, opened in 1984. A truncated section of Line 2, or the East–West Corridor, from Salt Lake Sector V to Phoolbagan opened in 2020. Line 3, or the Joka-Esplanade Corridor (currently truncated in Majerhat), opened in 2022. It is the fourth-longest operational metro network in India after the Delhi Metro, Namma Metro and Hyderabad Metro. (Full article...) -
Image 6County Road 492 (CR 492, Co. Rd. 492) is a primary county road in Marquette County, Michigan. The road serves as an alternate route between Negaunee and Marquette. Several historic sites line the roadway as it runs south and parallel to the main highway, U.S. Highway 41 (US 41) and M-28, through the Marquette Iron Range in Michigan's Upper Peninsula. The path of the road runs near tracks of the Lake Superior and Ishpeming Railroad (LS&I). The locally created Iron Ore Heritage Trail will follow CR 492 through Eagle Mills and Morgan Meadows upon completion. The western terminus of the county road is on US 41/M-28 in Negaunee and the eastern end is in Marquette next to Lake Superior.
CR 492 was previously known as the Marquette–Negaunee Road before it was made a part of the State Trunkline Highway System. It was originally designated as a part of M-15 as early as 1917. The superintendent of the Marquette County Road Commission, Kenneth Ingalls Sawyer, painted the first rural highway centerline on the roadway on Dead Man's Curve. The highway was later a part of M-28 before being transferred back to county control. The highway assumed its current form by 2001. The eastern section along Brookton Road in Marquette Township was redesignated as a county secondary highway when a new connection to US 41/M-28 was opened, and the designation was extended along Wright Street on the west and north sides of Marquette.

Image 11A disc of copper made by continuous casting, the process whereby molten metal is solidified into a "semifinished" state for subsequent rolling in the finishing mills. Continuous casting replaced the creation of ingots using stationary moulds. The process allows lower-cost production of metal sections with better quality, due to the inherently lower costs of continuous, standardised production of a product, as well as providing increased control over the process through automation. After casting, this disc was then etched to achieve its final state.

Image 17Photograph 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. -
