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 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...)

Most trains on the New York City Subway are manually operated. , the system currently uses automatic block signaling, with fixed wayside signals and automatic train stops. Many portions of the signaling system were installed between the 1930s and 1960s. Because of the age of the subway system, many replacement parts are unavailable from signaling suppliers and must be custom-built for the New York City Transit Authority, which operates the subway. Additionally, some subway lines have reached their train capacity limits and cannot operate extra trains in the current system.
There have been two different schemes of signaling in the system. The current scheme is used on all A Division and B Division lines, originally built to the Brooklyn–Manhattan Transit Corporation (BMT) and Independent Subway System (IND)'s specifications. An older system was previously used on all of the A Division, but with the conversion of the IRT Dyre Avenue Line signals to the B Division scheme in September 2017, this system is no longer in use.

Ås Station (Norwegian: Ås stasjon) is a railway station in Ås, Norway on the Østfold Line. The station was opened on 2 January 1879 and designed by Peter A. Blix in Swiss chalet style. The station was modernized in 1992, when the section between Ski and Moss was upgraded to double track and speeds up to 160 kilometres per hour (99 mph). In 2006, a cultural meeting place comprising a café, concert hall and an art exhibition was established inside the station's building, initiated by the local organization "Galleri Texas" and to the governmental corporation Follo Futura. Galleri Texas and Follo Futura had been arguing a while over how the operating of the café should be, and in 2010, all the maintenance and operation of the meeting place were transferred entirely from Galleri Texas to Follo Futura, since Galleri Texas no longer were satisfied with Follo Futuras work. The station is served by commuter trains on the Line L21 of the Oslo Commuter Rail, running from Stabekk over Oslo to Moss. Ski Station and Vestby Station are the preceding and the following stations, respectively. (Full article...) -
Image 3New York State Route 344 (NY 344) is a state highway located in Columbia County, New York, in the United States. The route is 1.90 miles (3.06 km) in length and serves primarily as an access road to the Bash Bish Falls state parks on both sides of the New York–Massachusetts border. The western terminus of NY 344 is at NY 22 in Copake Falls. Its eastern terminus is at the Massachusetts state line, where it continues into Bash Bish Falls State Park as Falls Road, a locally maintained highway. NY 344 was assigned c. 1932 and extended to its current length by 1953 after NY 22 was rerouted to bypass Copake Falls. (Full article...)

Image 4Interstate 35E (I-35E) is an Interstate Highway in the US state of Minnesota, passing through downtown Saint Paul. It is one of two through routes for I-35 through the Twin Cities of Minneapolis and Saint Paul, the other being I-35W through Minneapolis. Thus, both ends of I-35E are shared with I-35W and I-35.
During the early years of the Interstate Highway System, branching Interstates with directional suffixes, such as N, S, E, and W, were common nationwide. On every other Interstate nationwide, these directional suffixes have been phased out by redesignating the suffixed route numbers with a loop or spur route number designation (such as I-270 in Maryland, which was once I-70S) or, in some cases, were assigned a different route number (such as I-76, which was once I-80S). In the case of I-35 in the Twin Cities area, since neither branch is clearly the main route and both branches return to a unified Interstate beyond the cities of Minneapolis and Saint Paul, officials at the American Association of State Highway and Transportation Officials (AASHTO) have allowed the suffixes of E and W in Minnesota to remain in the present day. I-35 also splits into I-35E and I-35W in Dallas–Fort Worth, Texas, for similar reasons as the I-35 split in the Minneapolis–Saint Paul area. (Full article...) -

Ida Minerva Tarbell (November 5, 1857 – January 6, 1944) was an American writer, investigative journalist, biographer and lecturer. She was one of the leading muckrakers and reformers of the Progressive Era of the late 19th and early 20th centuries and was a pioneer of investigative journalism.
Born in Pennsylvania at the beginning of the oil boom, Tarbell is best known for her 1904 book The History of the Standard Oil Company. The book was first published as a series of articles in McClure's from 1902 to 1904. It has been called a "masterpiece of investigative journalism", by historian J. North Conway, as well as "the single most influential book on business ever published in the United States" by historian Daniel Yergin. The work contributed to the dissolution of the Standard Oil monopoly and helped usher in the Hepburn Act of 1906, the Mann-Elkins Act, the creation of the Federal Trade Commission (FTC), and the passage of the Clayton Antitrust Act of 1914.

Image 6State Route 133 (SR 133) is a state highway in the U.S. state of California, serving as an urban route in Orange County. It connects SR 1 in Laguna Beach through the San Joaquin Hills with several freeways in Irvine, ending at the SR 241, a toll road in the latter city. It is built as an expressway from SR 73 to Laguna Canyon Road (just south of I-405 in Irvine), and past this, SR 133 is a freeway (the Laguna Freeway) to I-5, and a tollway (part of the Eastern Transportation Corridor) to SR 241 near the Santa Ana Mountains.
SR 133 was constructed as a county road by the 1910s; the portion from I-405 to I-5 was upgraded to a freeway four decades later. The state canceled plans to extend the freeway segment south, and the southern part of the road remains an undivided highway. In 1998, most of the Eastern Transportation Corridor opened, and the connector between I-5 and SR 241 was designated as a toll extension of SR 133. (Full article...) -

State Route 971 (SR 971) is a state highway in the U.S. state of Washington. It runs for 15 miles (24 km) and primarily serves Lake Chelan State Park, with both of its termini at U.S. Route 97 Alternate (US 97A) southwest of Chelan. SR 971 has the highest highway number in the state.
The highway traverses Navarre Coulee along the route of a 19th-century road that was later connected to Chelan in the 1910s. Both roads were paved in the 1960s and incorporated into SR 971 when it was established by the state legislature in 1991. (Full article...)

Image 5Image credit: Joaquim Alves GasparAn animation showing how to use a vernier caliper, which is a caliper that uses a vernier scale to interpolate linear measurements. Vernier calipers can measure internal and external dimensions using, respectively, the uppermost and lower jaws, and also depths, using the depth probe (located at the right end). In this example, the first two digits (2.4) are decided by the location of the zero of the vernier scale in the centimeter scale, and the last digit (0.07), by the first line of the vernier scale that exactly matches a line of the centimeter scale above.

Image 6Photograph credit: Petar MiloševićA thermoplastic-sheathed cable consists of a toughened outer thermoplastic sheath of polyvinyl chloride, covering one or more individual annealed copper conductors. Each of the current-carrying conductors in the "core" is insulated by an individual thermoplastic sheath, coloured to indicate the purpose of the conductor concerned. The protective earth conductor may also be covered with insulation, although, in some countries, this conductor may be left as bare copper. The type of thermoplastic, the dimensions of the conductors and the colour of their individual insulation are specified by the regulatory bodies in the various countries concerned.

Image 8Photograph 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. -

Image 19Photograph 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. -
