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 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 products such as tools 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 prehistory, followed by the control of fire—which in turn contributed to the growth of the human brain and the development of language during the Ice Age, according to the cooking hypothesis. 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...)

  U.S. Route 66 (US 66, Route 66) also known as the Will Rogers Highway, was a major United States Numbered Highway in the state of Arizona from November 11, 1926, to June 26, 1985. US 66 covered a total of 385.20 miles (619.92 km) through Arizona. The highway ran from west to east, starting in Needles, California, through Kingman and Seligman to the New Mexico state line. Nationally, US 66 ran from Santa Monica, California, to Chicago, Illinois. In its height of popularity, US 66 was one of the most popular highways in the state of Arizona, sometimes carrying over one million cars a year.
  
  In the early years, US 66 had to compete with other major U.S. Highways for construction and improvement funding. The highway also played an important role during the Dust Bowl as a means for refugees (also known as "Okies") to escape the ruined farmlands of the Great Plains and migrate to California. The experiences of these refugees traveling through Arizona were largely detailed in John Steinbeck's novel, The Grapes of Wrath, and the 1940 movie adaption that followed. During the mid-20th century, the highway became a tourist destination, spawning the existence of several new motels, restaurants and other road-side businesses and attractions. (Full article...)

  Maryland Route 331 (MD 331) is a 28.74-mile (46.25 km) state highway on the Eastern Shore of Maryland in the United States. Signed north-south, the route runs from Vienna in Dorchester County northwest to Easton in Talbot County, intersecting U.S. Route 50 (US 50) at both ends. MD 331 is a two-lane undivided road most of its length that passes mostly through agricultural areas. The road also passes through the communities of Hurlock and Preston along the way. It encounters several routes during its journey, including MD 14 near Rhodesdale and MD 16 in the Preston area, both of which the route forms concurrencies with. In addition, the route also intersects with MD 392 and MD 307 in Hurlock and with MD 318 near Preston.
  
  Most of present-day MD 331 was designated as part of US 213 in 1926 when the U.S. Highway System was established. By 1940, US 213 was moved to a new alignment that crossed the Choptank River at Cambridge on a bridge built in 1935 and MD 331 was designated to run from Vienna to Easton. Both ends of MD 331 have been shortened since, with the southernmost portion of MD 331 curtailed following the completion of the US 50 bypass of Vienna by the 1990s and the northern terminus of the route cut back to US 50 in 2004 when the state-maintained portion of Dover Road to Dover Street in Easton was turned over to the city.

  State Route 224 (SR 224) is a 10.15-mile (16.33 km) long state highway located entirely in Benton County, Washington, United States. The highway serves to connect SR 225 to Interstate 82 (I-82) and U.S. Route 12 (US 12), and to link Benton City to West Richland and Richland. Before the 1964 state highway renumbering the highway was numbered Secondary State Highway 3R. SR 224 is a lightly traveled rural highway except through Richland, where an average of 16,000 cars traveled the highway daily in 2009. The Washington State Department of Transportation (WSDOT) rebuilt its southern terminus as a roundabout in 2016, as part of a project to improve traffic congestion near the Red Mountain AVA.

  Interior of the Transportation Hub in August 2016

  
  World Trade Center station is a terminal station on the PATH system, within the World Trade Center complex in the Financial District of Manhattan, New York City. It is served by the Newark–World Trade Center line at all times, as well as by the Hoboken–World Trade Center line at all times except nights, and is the eastern terminus of both.
  
  The World Trade Center station is near the site of the Hudson and Manhattan Railroad's (H&M) Hudson Terminal, which opened in 1909. The Port Authority of New York and New Jersey bought the bankrupt H&M system in 1961, rebranded it as PATH, and redeveloped Hudson Terminal as part of the World Trade Center. The World Trade Center station opened on July 6, 1971, as a replacement for Hudson Terminal, which was closed and demolished as part of the construction of the World Trade Center. Following the September 11 attacks, a temporary PATH station opened in 2003 while the World Trade Center complex was being rebuilt. Work on a permanent station building commenced in 2008. The main station house, the Oculus, opened on March 3, 2016, and the terminal was renamed the World Trade Center Transportation Hub, or "World Trade Center" for short. (Full article...)

  Both spans of the Chesapeake Bay Bridge

  
  The Gov. William Preston Lane Jr. Memorial Bridge (informally called the Chesapeake Bay Bridge and, locally, the Bay Bridge) is a major dual-span bridge in the U.S. state of Maryland. Spanning the Chesapeake Bay, it connects the state's rural Eastern Shore region with its urban and suburban Western Shore, running between Stevensville and Sandy Point State Park near the capital city of Annapolis. The original span, opened in 1952 and with a length of 4 miles (6.4 km), was the world's longest continuous over-water steel structure. The parallel span was added in 1973. The bridge is named for William Preston Lane Jr., who, as the 52nd Governor of Maryland, launched its construction in the late 1940s after decades of political indecision and public controversy.
  
  The bridge is part of U.S. Route 50 (US 50) and U.S. Route 301 (US 301), and serves as a vital link in both routes. As part of cross-country US 50, it connects the Baltimore–Washington Metropolitan Area with Ocean City, Maryland, Rehoboth Beach, Delaware, and other coastal tourist destinations. As part of US 301, it serves as part of an alternative route for Interstate 95 travelers, between northern Delaware and the Washington, D.C., area. The bridge is busy and often congested with traffic, particularly during peak hours and summer months. (Full article...)

  Trojan Room coffee pot

  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.

  Pitstone Windmill, believed to be the oldest windmill in the British Isles
  
  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.

  Rail transport is a means of conveyance of passengers and goods by way of wheeled vehicles running on rail tracks. The oldest, man-hauled railways date to the 6th century B.C.; the method grew more popular after the introduction of steam locomotives in the 19th century. Here we can see four BNSF GE C44-9W diesel locomotives hauling a mixed freight train along the Columbia River in the US.
