Supersonic speed is a rate of travel of an object that exceeds the speed of sound (Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level, this speed is approximately 343.2 m/s, 1,125 ft/s, 768 mph, 667 knots, or 1,235 km/h. Speeds greater than five times the speed of sound (Mach 5) are often referred to as hypersonic. Flights during which only some parts of the air surrounding an object, such as the ends of rotor blades, reach supersonic speeds are called transonic. This occurs typically somewhere between Mach 0.8 and Mach 1.23.
Sounds are traveling vibrations in the form of pressure waves in an elastic medium. In gases, sound travels longitudinally at different speeds, mostly depending on the molecular mass and temperature of the gas, and pressure has little effect. Since air temperature and composition varies significantly with altitude, Mach numbers for aircraft may change despite a constant travel speed. In water at room temperature supersonic speed can be considered as any speed greater than 1,440 m/s (4,724 ft/s). In solids, sound waves can be polarized longitudinally or transversely and have even higher velocities.
"Supersonic" is the debut single by the English rock band Oasis, written by lead guitarist Noel Gallagher. The song appears on their debut album Definitely Maybe, released in August 1994.
The song was released on 11 April 1994 and peaked at number 31 on the UK Singles Chart, Oasis's lowest-peaking single. However, over time it has amassed sales of over 215,000, making it their 13th biggest selling single ever in the UK, even outselling their 2002 number one "The Hindu Times", and both of their 2005 number ones, "Lyla" and "The Importance of Being Idle".
"Supersonic" was also the band's first single to chart in the United States, where it peaked at number 11 on the US Billboard Modern Rock Tracks chart on 10 December 1994. The song was performed by the band on their debut national TV performance on Channel 4's The Word. It remains a favourite song of both the band and their fans (on the Definitely Maybe DVD, Noel cites it as his favourite Oasis song). The single went silver in the UK in 2006.
"Supersonic" is a 1988 single by J.J. Fad from their self-titled debut album. It reached #10 on the Billboard Hot Dance/Club Play Songs and #22 on the Hot R&B/Hip-Hop Singles & Tracks chart. "Supersonic" stayed on the dance charts for eight weeks. The song went gold, and also got nominated for a Grammy Award for Best Rap Performance in 1989, making them the first all-female rap group to be nominated for a Grammy award.
Letterpress printing is a technique of relief printing using a printing press, a process by which many copies are produced by repeated direct impression of an inked, raised surface against sheets or a continuous roll of paper. A worker composes and locks movable type into the "bed" or "chase" of a press, inks it, and presses paper against it to transfer the ink from the type which creates an impression on the paper.
In practice, letterpress also includes other forms of relief printing with printing presses, such as wood engravings, photo-etched zinc "cuts" (plates), and linoleum blocks, which can be used alongside metal type, or wood type, in a single operation, as well as stereotypes and electrotypes of type and blocks. With certain letterpress units it is also possible to join movable type with slugs cast using hot metal typesetting. In theory, anything that is "type high" or .918 inches can be printed using letterpress
Letterpress printing was the normal form of printing text from its invention by Johannes Gutenberg in the mid-15th century until the 19th century and remained in wide use for books and other uses until the second half of the 20th century. Letterpress printing remained the primary way to print and distribute information until the 20th century, when offset printing was developed, which largely supplanted its role in printing books and newspapers. All forms of data collection were affected by the invention of letterpress printing, as were many careers such as teachers, preachers, physicians and surgeons and artist-engineers. More recently, letterpress printing has seen a revival in an artisanal form.
Robert Chase, M.D. is a fictional character on the Fox medical drama House. He is portrayed by Jesse Spencer. His character was a part of the team of diagnosticians who worked under Gregory House until the end of the third season when House fires him. However, he resumed work at the hospital as a surgeon, and was re-hired by House in season 6. Robert Chase is the longest-serving member of House's staff. Chase has been attracted to Allison Cameron since the beginning of the show and embarks on a romantic relationship with her in "Human Error." In "Post Mortem," he left the Diagnostic Team after realizing he was in the same position as he was 10 years earlier, unlike all of the other former members of the team. However, in the series finale, he rejoins the hospital as the new Head of Diagnostic Medicine, replacing House, who is thought to have died.
An Australian, Chase is portrayed as an eager fellow of House during the first 3 seasons, often supporting his opinions and carrying out his orders without question. He was raised Catholic, and in the Season 1 episode "Damned If You Do," it was revealed that he attended seminary before becoming a doctor. He seems to trust House the most and sometimes takes part in House's morally questionable plans when the other members of the team have refused, showing a situational application of ethics and a flexible stance on morality. This leads to tension between Chase and Foreman, who is quick to disagree with House and prove him wrong.
Chase is a given name and surname in the English language, especially in the United States. The given name is a transferred use of the surname.
