P:TECH

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...)

State Route 46 (SR 46) is an east–west state highway in the U.S. state of California. It is a major crossing of the Coast Ranges and it is the southernmost crossing of the Diablo Range, connecting SR 1 on the Central Coast near Cambria and US 101 in Paso Robles with SR 99 at Famoso in the San Joaquin Valley.

The road that is now SR 46 was built and improved during the 1920s and was fully paved by 1930. The majority of SR 46 was originally designated as U.S. Route 466; however, after the latter was entirely removed from the U.S. Highway system, the eastern portion of the route became SR 46.

There are active proposals to build a new station in South Bend, Indiana, for the South Shore Line commuter rail service to replace the existing South Bend Airport station. The existing South Bend Airport station, built in 1992 on the east side of the airport, is a terminus for the train service. The route that carries the South Shore Line to its current station is considered slow and circuitous. While a number of locations have been looked at, the primary contenders have been relocating the station to the west side of South Bend International Airport or building a station in Downtown South Bend. Construction of a station in Downtown South Bend was championed by Pete Buttigieg during his tenure as mayor of South Bend. In late 2022, the Northern Indiana Commuter Transportation District (NICTD), the operator of the South Shore Line, advanced plans to begin construction on a new station at the west side of the airport as early as late 2024, commissioning an engineering study to prepare for this. Even if it builds a new station on the west side of the airport, NICTD has not ruled out the possibility of also building a future connection to Downtown South Bend.

When it was first opened in 1992, the current station on the airport's east side was originally intended to be a temporary location for the city's station. In 2006, officials began advancing plans to move the station to the airport's west side. In 2017, these plans again began gathering support. However, soon after, proposals for alternate locations for a station began to arise. The South Bend Chocolate Company proposed locating the station near tourist attractions it was planning to construct. Then-mayor Pete Buttigieg (who had previously supported the plans to relocate the station to the west side of the airport) proposed instead locating the station in downtown South Bend. In 2018, a study was conducted analyzing possible sites for the station (the west side of the airport, downtown South Bend, a location on Honeywell Corporation-owned property, the South Bend Amtrak station, and the South Bend Chocolate Factory site). After the study, both Buttigieg and NICTD president Michael Noland both agreed that the only two sites worth further consideration for a new station were the west side of the airport and downtown South Bend. Later in 2018, the City of South Bend commissioned a further study of the feasibility for a downtown station. NICTD, by 2022, was progressing with plans for a new station on the west side of the airport. Public debate on whether this or a downtown station has persisted, however. (Full article...)

Deli Mike in 2013

Deli Mike or Deli Mayk (English: Crazy Mike) is a nickname given to an Airbus A340-300 operated by Turkish Airlines with civil registration TC-JDM. The aircraft joined the Turkish Airlines fleet in 1996 to replace the McDonnell Douglas DC-10s of the airline and was used to operate long-haul flights out of Turkey. During its operation, Deli Mike had a record of having minor and strange technical failures such as its lights illuminating differently. This unreliability gave the aircraft its nickname, which is a wordplay on the ICAO spelling alphabet. In its late use, the aircraft operated both long-haul and short-haul flights. It was re-configured in 2016 to only have economy class seats and was solely used to carry pilgrims to Hajj.

Deli Mike was removed from the Turkish Airlines fleet in early 2019 and was flown to O. R. Tambo International Airport later that year and re-registered as 2-AVRA. After being stored at Johannesburg for almost 4 years, the aircraft was flown to Mehrabad International Airport in December 2022. The aircraft was allegedly acquired by a Burkinabe subsidiary of Iranian carrier Mahan Air in order to evade sanctions placed on the airline and country. The aircraft commenced operations with airline in March 2024 as EP-MJC. (Full article...)

The IND Culver Line's bridge over Fourth Avenue

The Fourth Avenue/Ninth Street station is a New York City Subway station complex shared by the elevated IND Culver Line and the underground BMT Fourth Avenue Line. It is located at the intersection of Ninth Street and Fourth Avenue in Park Slope, Brooklyn and served by the:
- F, G and R trains at all times
- D and N trains late nights
- W train during rush hours only, with some trips in the peak direction
The Ninth Street portion of the station was constructed as part of the Fourth Avenue Line, which was approved in 1905. Construction on the segment of the line that includes Union Street started on December 20, 1909, and was completed in September 1912. The station opened on June 22, 1915, as part of the initial portion of the BMT Fourth Avenue Line to 59th Street. The station's platforms were lengthened in 1926–1927, and again in 1970. The Fourth Avenue portion was built as part of the Culver Line of the city-operated Independent Subway System, and was constructed as an elevated station so the line could pass over the Gowanus Canal to the west. This station opened on October 7, 1933. The two stations were consolidated into a single station complex on May 28, 1959. (Full article...)

In Oklahoma, U.S. Highway 62 (US 62) runs diagonally across the state, from the Texas state line in far southwestern Oklahoma to the Arkansas state line near Fayetteville. US-62 spends a total of 402.48 miles (647.73 km) in the Sooner State. The highway passes through fifteen of Oklahoma's counties. Along the way the route serves two of Oklahoma's largest cities, Lawton and Oklahoma City, as well as many regionally important cities, like Altus, Chickasha, Muskogee, and Tahlequah. Despite this, US-62 has no lettered spur routes like many other U.S. routes in Oklahoma do.

Since 1930, US-62 has been a part of Oklahoma's highway system. The section of the Interstate system's route that passes through Oklahoma City was altered several times after it was established in order to accommodate the presence of the new freeways. The present-day route of US-62 includes concurrencies with I-44, I-240, I-35, and I-40. (Full article...)

Kominato Station in October 2023
Kominato Station (小湊駅, Kominato-eki) is a railway station of the Aoimori Railway Line located in the central district of the town of Hiranai in Aomori Prefecture, Japan. The station has been operating since 1891, though the most recent station building, which consists of a side platform and an island platform connected to the station building by a footbridge, was completed in 1986. Since 2010, the station has been operated by the Aoimori Railway Company, a third sector, regional rail operator. It is the busiest railway station in Hiranai.

Passenger trains serve the station 17 hours a day; the departure time between trains is roughly 30 minutes during the morning peak with reduced frequency at other times. The station also serves as a bus station for Shimokita Kōtsu [ja], with local bus routes connecting the station and central Hiranai to communities throughout the town. (Full article...)

Trojan Room coffee pot
Picture: Quentin Stafford-Fraser
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.

The Australia Telescope Compact Array is a radio telescope operated by the Commonwealth Scientific and Industrial Research Organisation (CSIRO) at the Paul Wild Observatory, 25 km (16 mi) west of the town of Narrabri in New South Wales, Australia. The telescope is an array of six identical dishes each 22 metres (72 ft) in diameter, which commonly operate in aperture synthesis mode to produce images from radio waves. Five of the dishes can be moved along a 3-kilometre (2 mi) railway track; the sixth is situated three kilometres west of the end of the main track. Each dish weighs about 270 tonnes (270 long tons; 300 short tons).

This photograph, showing five of the Australia Telescope Compact Array's dishes, was taken around 1984, in the late phase of the construction process. It is a long-exposure photograph taken in darkness in the late evening; during the exposure, the photographer, John Masterson, walked around the dishes firing off over 130 flashes using a hand-held flash gun.

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.
