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...)

The Port of Split (Croatian: Luka Split) is a port in the central Dalmatian city of Split, Croatia. The port was originally a trading post originally established by Greek settlers from the island of Vis and subsequently taken over by the Romans. The port thrived through the Middle Ages, but it suffered a decline in the late 18th and early 19th centuries when the Port of Rijeka took over as the primary trading and shipping outlet of the region. The decline was also attributed to the decline of the Ottoman Empire, a traditional market for the Port of Split, and the growing domination of Austrian Empire.
As of 2017, the port ranks as the largest passenger port in Croatia, the largest passenger port in the Adriatic, and the 11th largest port in the Mediterranean, with annual passenger volume of approximately 5 million. By 2010, the Port of Split recorded 18,000 ship arrivals each year. The port is managed by the Port of Split Authority (PSA). In the late 2000s, the PSA and the port operators, Trajektna Luka Split d.d. and Luka d.d. Split, started to implement an investment plan aimed at increasing both passenger and cargo traffic volume, scheduled to be completed by 2015, which would allow the port to handle up to 7 million passengers per year.

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...) -
Image 3King's Highway 40, commonly referred to as Highway 40, is a provincially maintained highway in the southwestern portion of the Canadian province of Ontario. The 91.4-kilometre (56.8 mi) route links Chatham and Sarnia via Wallaceburg, following close to the St. Clair River. The southern terminus is at Highway 401 south of Chatham, while the northern terminus is at Highway 402 in Sarnia. The portion of Highway 40 between Highway 401 and north of Wallaceburg is within the municipality of Chatham-Kent, while the portion north of there is within Lambton County.
Highway 40 was built as a depression-relief project in 1934. The original routing followed what is now the St. Clair Parkway, but was rerouted to create that scenic road in the mid-1970s. The Sarnia Bypass was opened in 1963 as Highway 40A and renumbered as Highway 40 by 1966; the original route through Sarnia became Highway 40B until it was decommissioned during the early-1990s. The route was extended to Highway 3 in Blenheim during the early 1970s; however this section was decommissioned during the Ontario highway transfers in 1998. (Full article...) -
Image 4The E. C. Row Expressway is a municipal expressway in the city of Windsor, Ontario, Canada. It divides the city in half as it crosses it between the Ojibway Parkway in the west and Banwell Road in the east, a distance of 15.4 kilometres (9.6 mi). It was built between 1971 and 1983, reaching completion across the city on June 9, 1983. It was part of Highway 2 and Highway 18 until the province transferred ownership and responsibility for the route to the City of Windsor on April 1, 1997. In 2015, the westernmost 3 kilometres (1.9 mi) was significantly upgraded as part of the Highway 401 extension (Herb Gray Parkway) project. The freeway is named after Edward Charles Row, the president of Chrysler Canada between 1951 and 1956.
While allowing for easy travel across the city, the E. C. Row Expressway was isolated for much of its existence as it did not connect directly to the United States nor Highway 401; drivers had to access the Ambassador Bridge via Huron Church Road, or the Detroit–Windsor Tunnel via Dougall Parkway, both surface streets were also needed to reach Highway 401. This situation is being rectified from 2011 onward, as the expressway's western terminus is located at the port of entry for the Gordie Howe International Bridge scheduled for completion in 2025, with slip ramps to access the bridge-bound portion of Highway 401.

Image 7Iowa Highway 85 (Iowa 85) is a short state highway in east-central Iowa. The route begins at the eastern city limit of Montezuma and ends at Iowa 21 east of Deep River. Created in 1920 as a spur route connecting What Cheer to Primary Road No. 2, it is an original route in the Iowa primary highway system. In the early 1930s, the route was extended north to Deep River and west to Montezuma. By the end of the decade, Iowa 21 had taken over the north–south portion of the route. Except for both endpoints shifting slightly, Iowa 85 has largely stayed the same since the 1930s. (Full article...)

Image 4Photograph: UberprutserA windmill is a mill that converts the energy of wind into rotational energy by means of vanes called sails or blades. Traditional windmills were often used to mill grain, pump water, or both. Most modern windmills take the form of wind turbines used to generate electricity, or windpumps used to pump water, either for land drainage or to extract groundwater.
Here, the smock mill Goliath is viewed in front of the wind farm Growind in Eemshaven in the Netherlands. -

Image 6Photograph credit: Unknown; restored by Adam CuerdenGeorge 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. -
Image 7The Trojan Room coffee pot was the inspiration for the world's first webcam. The coffee pot was located in the corridor just outside the so-called Trojan Room within the old Computer Laboratory of the University of Cambridge. The webcam was created in 1991 to help people working in other parts of the building avoid pointless trips to the coffee pot by providing, on the user's desktop computer, a live 128×128 pixel greyscale picture of the state of the coffee pot. The webcam was shut down on 22 August 2001, following the Computer Laboratory's move to the William Gates Building.

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. -
