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 knowledge for achieving practical goals 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...)

  Maryland Route 537 (MD 537) is a collection of unsigned state highways in the U.S. state of Maryland. These two existing highways and two former sections of state highway are segments of the old alignment of U.S. Route 213 (US 213), which is now MD 213, in Chesapeake City in southern Cecil County. Some of the roads that became segments of MD 537 were constructed in the mid-1910s as part of the original state road between Elkton and Cecilton. Other portions of MD 537 were part of the approach roads to a bridge across the Chesapeake & Delaware Canal that was built in the mid-1920s and destroyed in 1942. After the modern Chesapeake City Bridge and its approach roads were completed in 1949, US 213 was moved to the new bridge and approach roads and MD 537 was assigned to the bypassed sections of US 213. Much of MD 537 outside of Chesapeake City was transferred to county maintenance in the late 1950s. In 2015, the remaining section of MD 537 north of the canal was turned over to municipal maintenance. (Full article...)

  New York State Route 37 (NY 37) is a state highway in the North Country of New York in the United States, extending for 127.40 miles (205.03 km) on a west–east axis. The western terminus of the route is at an intersection with U.S. Route 11 (US 11) in Pamelia, Jefferson County. Its eastern terminus is at a junction with US 11, NY 11B, and NY 30 in Malone, Franklin County. In between the termini, NY 37 passes through Ogdensburg and Massena. It is a two-lane, nondivided, full access roadway for most of its entire length, except for portions between Massena and western Franklin County, where the route widens to a four-lane divided highway.
  
  NY 37 was assigned in 1930 to the portion of the Theodore Roosevelt International Highway between Redwood and Malone as well as to a previously unnumbered roadway between Watertown and Redwood. The Redwood–Malone portion was originally part of NY 3 when the first set of posted routes in New York were assigned in 1924. NY 37 has since been rerouted in areas, primarily near Ogdensburg and Massena. (Full article...)

  New York State Route 38 (NY 38) is a north–south state highway in the Finger Lakes region of New York in the United States. Its southern terminus is at an intersection with NY 96 in the town of Owego in Tioga County. The northern terminus is at a junction with NY 104A in the town of Sterling in Cayuga County. NY 38 is a two-lane local road for most of its length. The route is the main access road to parts of Auburn, Dryden, Newark Valley and Port Byron. It passes through mountainous terrain in Tioga and Cortland counties, but the terrain levels out as it heads through the Finger Lakes area and Cayuga County.
  
  The route intersects several long-distance highways, including NY 13 in Dryden, U.S. Route 20 (US 20) and NY 5 in Auburn, and NY 31 in Port Byron. It passes over the New York State Thruway (Interstate 90 or I-90) north of Port Byron; however, there is no connection between the two. NY 38 has two suffixed routes. The first, NY 38A is an alternate route of NY 38 between Moravia and Auburn, while the other, NY 38B, is a simple east–west connector in the Southern Tier. While NY 38 runs along the western shore of Owasco Lake, NY 38A travels to Auburn along a routing east of the lake. (Full article...)

  The River Road National Scenic Byway (also called the River Road National Forest Scenic Byway) is a National Scenic Byway and National Forest Scenic Byway in the US state of Michigan. This 23+1⁄2-mile-long (37.8 km) byway follows M-65 and River Road; it extends eastward into the Huron National Forest and ends in the historic community of Oscoda near Lake Huron. The road parallels the historic Au Sable River (French: Rivière aux Sable, "River of Sand") which has historically been a major transportation route for floating Michigan's giant white pine from the forest to the saw mill towns on Lake Huron. Along its course, the roadway offers access to several recreational areas as well as the local scenery. The section of the River Road that follows M-65 was added to the State Trunkline Highway System in the 1930s. The River Road was given National Forest Scenic Byway status in 1988, and National Scenic Byway status in 2005. (Full article...)

  New York State Route 38A (NY 38A) is a north–south state highway located within Onondaga and Cayuga counties in central New York in the United States. The southern terminus of the route is at an intersection with NY 38 in the village of Moravia. Its northern terminus is at a junction with U.S. Route 20 (US 20) and NY 5 in downtown Auburn. Much of NY 38A runs through rural, undeveloped areas situated between Owasco Lake and Skaneateles Lake.
  
  The southern half of NY 38A was originally designated as part of NY 26 in 1924. In the 1930 renumbering of state highways in New York, NY 26 was broken up into several routes, including NY 38A, a new route assigned to NY 26's former alignment between Moravia and Skaneateles and a previously unnumbered highway from Skaneateles to Auburn.

  Fuel injection

  Image credit: WikipedianProlific

  An animated cut-away diagram of a typical fuel injector, which is used to spray controlled amounts of petrol (gasoline) into an internal combustion engine. A solenoid is activated when fuel is intended to be delivered to the engine, causing the plunger to become pulled toward the solenoid by magnetic force. This uncovers the valve opening, allowing fuel to flow into the atomiser and out the spray tip. The route of fuel is shown in orange; grey/blue indicates no fuel present.

  Continuous casting

  Photo: Alchemist-hp

  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.
