First announced in August 2012 as part of the Thomson line (TSL), the station was constructed as part of TEL Phase 2 (TEL2) with the merger of the TSL and the Eastern Region line (ERL). The station's construction required multiple traffic diversions along Upper Thomson Road along with a canal. Opening on 28 August 2021 along with the TEL2 stations, Upper Thomson station features Lost In Our (Concrete) Jungle by Troy Chin as part of the Art-in-Transit programme. (Full article...)
The freeway was authorized in 1975, and most of the sections were completed by 2000 (7.2mi or 11.6km); the 2.6-mile (4.2km) section westward to CR81 in Maple Grove was completed and opened in 2011. The Minnesota Department of Transportation (MnDOT) opened the last segment extending to I-94 on December 9, 2016. (Full article...)
Interstate370 (I-370) is a 2.54-mile (4.09km) Interstate Highway spur route off I-270 in Gaithersburg, Maryland, to the western end of the Maryland Route 200 (MD200, Intercounty Connector) toll road at an interchange that provides access to the park and ride lot at the Shady Grove station on the Red Line of the Washington Metro. Despite the number, I-370 does not connect to I-70 itself. The road continues to the west of I-270 as Sam Eig Highway, a surface road. Along the way, I-370 has interchanges with MD355 and Shady Grove Road. The freeway was completed in the late 1980s to connect I-270 to the Shady Grove station. I-370 was always part of the planned Intercounty Connector but was the only segment to be built at the time. The opening of MD200 east of I-370 resulted in the truncation of I-370 to the interchange with MD200 and the redesignation of the road leading into the Shady Grove station as MD200A.

Manresa Island is a former island located in Norwalk, Connecticut, at the mouth of Norwalk Harbor in the Long Island Sound. The earliest name for the landform was Boutons Island, which dates to 1664. By the 19th century, the island had been purchased by John H. Keyser, who lived there and cultivated rare vegetation. He built a causeway in 1860, connecting the island to the mainland of South Norwalk. This gave rise to the name Keyser Island, which was sold to the Jesuits toward the end of the century.
On the island, the Jesuits established the Manresa Institute, which was the only dedicated retreat center in the United States. It hosted both prominent Catholicprelates as well as laymen, as part of a growing lay retreat movement in the United States. The institute was named for the Spanish town of Manresa, in which Saint Ignatius of Loyola, the founder of the Society of Jesus, wrote his Spiritual Exercises. In 1911, the Jesuits sold Keyser Island, which became known as Manresa Island in the mid-twentieth century. (Full article...)
SR16 was created during the 1964 state highway renumbering as the successor to Primary State Highway14 (PSH14). PSH14, which had itself been the successor to State Road14, traveled northeast from Shelton to Gorst and south to Gig Harbor. PSH14 was extended over the Tacoma Narrows in 1939 on the unfinished Tacoma Narrows Bridge, which would later collapse months after opening in 1940, into Tacoma over Secondary State Highway14C (SSH14C). SR16 has been expanded into a freeway in stages beginning with the original Nalley Valley Viaduct in Tacoma in 1971, and ending with the opening of an interchange near Port Orchard in 2009. Later improvements to the corridor include the installation of high-occupancy vehicle lanes that connect to I-5 and the rest of the freeway network in Pierce County, which were completed in 2019.

M-115 was first designated in the 1920s on the northwestern end near Frankfort. Additional, disconnected sections were designed as part of the trunkline in the 1930s near Cadillac, Farwell and Mesick. All but one of these gaps (Cadillac–Mesick) was eliminated by the end of that decade. The remaining segment was built in the 1950s to unite M-115 into a single highway. The last change came in 1989 when the highway was extended into Clare to its current southern terminus. (Full article...)
An 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.
An escalator is a moving staircase for carrying people between floors of a building. The device consists of a motor-driven chain of individual, linked steps that move up or down on tracks, allowing the step treads to remain horizontal.
A 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.
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.
A diagram of a typical turbojet engine. Air is compressed as it enters the engine, and is mixed with fuel that burns in the combustion section. Released through the exhaust, the resulting hot gases provide forward thrust and turn the turbines that drive the fan blades of the compressor.
The SOCATA TBM (now Daher TBM) is a family of high-performance single-engine turboprop business and utility light aircraft manufactured by Daher. This SOCATA TBM900 was photographed in flight during the 2015 EAA AirVenture Oshkosh airshow in the U.S. state of Wisconsin. The aircraft features a Pratt& Whitney Canada PT6A-64 engine, and a five-blade carbon-fiber propeller, which increases performance and decreases cabin noise. In a passenger configuration, the pressurized cabin is typically fitted with highly finished interiors, featuring luxury materials such as leather and wood veneers.
The 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.
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 (292ft) high, 210 metres (690ft) long, and has a main span of 55 metres (180ft). In 1926, the viaduct was the inspiration for Ernst Ludwig Kirchner's painting Brücke bei Wiesen.
