Apollo (1910 automobile)
The Apollo was a German automobile manufactured by Ruppe & Son of Apolda in Thuringia from 1910 to 1927; the company had previously offered a car called the Piccolo. The first Apollo was called the "Mobbel", and featured an air-cooled 624cc single-cylinder ioe engine. The company also offered air-cooled 1608 cc in-line fours and a 1575 cc V-4. Four separate cylinders inline powered the model "E" (1770cc). The model "B", designed by racing driver Karl Slevogt, had an ohv 960 cc four-cylinder engine. Another of the designer's fine creations had an ohv 2040 cc engine. Other Apollos had sv four-cylinder engines of up to 3440 cc; some post-1920 models featured wishbone suspension. The last cars produced by the company had ohv 1200 cc four-cylinder engines; some had sv 1551 Steudel four-cylinder power units instead. The famous designer of two-stroke engines, Hugo Ruppe, was the factory founder's son; in 1920 Apollo took over his air-cooled MAF cars. During the mid-1920s, Slevogt raced cars of this marque with streamlined Jaray bodies.
Apollo 16
Apollo 16 was the tenth manned mission in the United States Apollo space program, the fifth and penultimate to land on the Moon and the first to land in the lunar highlands. The second of the so-called "J missions," it was crewed by Commander John Young, Lunar Module Pilot Charles Duke and Command Module Pilot Ken Mattingly. Launched from the Kennedy Space Center in Florida at 12:54 PM EST on April 16, 1972, the mission lasted 11 days, 1 hour, and 51 minutes, and concluded at 2:45 PM EST on April 27.
John Young and Charles Duke spent 71 hours—just under three days—on the lunar surface, during which they conducted three extra-vehicular activities or moonwalks, totaling 20 hours and 14 minutes. The pair drove the Lunar Roving Vehicle (LRV), the second produced and used on the Moon, 26.7 kilometers (16.6 mi). On the surface, Young and Duke collected 95.8 kilograms (211 lb) of lunar samples for return to Earth, while Command Module Pilot Ken Mattingly orbited in the Command/Service Module (CSM) above to perform observations. Mattingly spent 126 hours and 64 revolutions in lunar orbit. After Young and Duke rejoined Mattingly in lunar orbit, the crew released a subsatellite from the Service Module (SM). During the return trip to Earth, Mattingly performed a one-hour spacewalk to retrieve several film cassettes from the exterior of the Service Module.
Apollo 15
Apollo 15 was the ninth manned mission in the United States' Apollo program, the fourth to land on the Moon, and the eighth successful manned mission. It was the first of what were termed "J missions", long stays on the Moon, with a greater focus on science than had been possible on previous missions. It was also the first mission on which the Lunar Roving Vehicle was used.
The mission began on July 26, 1971, and ended on August 7. At the time, NASA called it the most successful manned flight ever achieved.
Commander David Scott and Lunar Module Pilot James Irwin spent three days on the Moon, including 18½ hours outside the spacecraft on lunar extra-vehicular activity (EVA). The mission landed near Hadley rille, in an area of the Mare Imbrium called Palus Putredinus (Marsh of Decay). The crew explored the area using the first lunar rover, which allowed them to travel much farther from the Lunar Module (LM) than had been possible on missions without the rover. They collected 77 kilograms (170 lb) of lunar surface material. At the same time, Command Module Pilot Alfred Worden orbited the Moon, using a Scientific Instrument Module (SIM) in the Service Module (SM) to study the lunar surface and environment in great detail with a panoramic camera, a gamma-ray spectrometer, a mapping camera, a laser altimeter, a mass spectrometer, and a lunar sub-satellite deployed at the end of Apollo 15's stay in lunar orbit (an Apollo program first).
Asterisk
An asterisk (*; from Late Latin asteriscus, from Ancient Greek ἀστερίσκος, asteriskos, "little star") is a typographical symbol or glyph. It is so called because it resembles a conventional image of a star. Computer scientists and mathematicians often vocalize it as star (as, for example, in the A* search algorithm or C*-algebra). In English, an asterisk is usually five-pointed in sans-serif typefaces, six-pointed in serif typefaces, and six- or eight-pointed when handwritten. It can be used as censorship. It is also used on the internet to correct one's spelling, in which case it appears after or before the corrected word.
The asterisk is derived from the need of the printers of family trees in feudal times for a symbol to indicate date of birth. The original shape was seven-armed, each arm like a teardrop shooting from the center.
In computer science, the asterisk is commonly used as a wildcard character, or to denote pointers, repetition, or multiplication.
Usage
Censorship
When toning down expletives, asterisks are often used to replace letters. For example, the word 'fuck' might become 'f*ck' or even '****'.
If You're Reading This It's Too Late
If You're Reading This It's Too Late is the fourth mixtape by Canadian recording artist Drake. It was released through the iTunes Store without prior announcement on February 13, 2015, by Cash Money Records. The physical edition of the project was released by Cash Money as well as OVO Sound and Republic Records. There was a debate whether this project is a mixtape or a studio album, as it was released commercially through his record label, while Drake himself referred to the project as a mixtape.
The project received positive reviews and debuted at number one on the US Billboard 200, with three-day sales of 495,000 copies and 40,000 for online streaming credits, making this Drake's fourth time at the top of the chart. The album also broke Spotify's first-week streaming record with over 17.3 million streams in the first three days. The record was previously held by Drake himself, with his album Nothing Was the Same (2013), with 15.146 million streams in the first week.
Electric Shock (EP)
"Electric Shock" is the second studio extended play (EP) by South Korean girl group f(x). The EP was released digitally on June 10, 2012, and released physically on June 13, 2012, under S.M. Entertainment. The EP's title track, "Electric Shock", as well as the EP, reached at the top spot on the weekly Gaon Charts. The EP sold a total of more than 70,000 copies in South Korea.
Composition
The EP's single and title track, "Electric Shock", is an electronic-dance song. The lyrics starting each line with the word, "jeongichunggyeok" ("electric shock" in English). It was written and arranged by Willem Laseroms, Maarten Ten Hove and Joachim Vermeulen Windsant, and produced by Future Presidents. The music video was released on June 11, 2012, and was choreographed by Jillian Meyers.
The track "Jet" is composed by SM Entertainment's songwriter Kenzie, the track has hip-hop rhythms and electronic dance; Amber co-wrote the rap.
The track "Zig Zag" was especially produced to focus on the "youthful and refreshing blend of vocals" of f(x) members which adds to the urban electronic sound created by the use of electric guitars and drum beats. The track was composed and written by music producer Hitchhiker. The lyrics were penned by Kim Bumin who often works closely with Hitchhiker.
Jet (fluid)
A jet is a stream of fluid that is projected into a surrounding medium, usually from some kind of a nozzle, aperture or orifice. Jets can travel long distances without dissipating. In the Earth's atmosphere there exist jet streams that travel thousands of kilometres.
Jet fluid has higher momentum compared to the surrounding fluid medium. In the case where the surrounding medium is assumed to be made up of the same fluid as the jet, and this fluid has a viscosity, than the surrounding fluid near the jet is assumed to be carried along with the jet by a process called entrainment.
Some animals, notably cephalopods, use a jet to propel themselves in water. Similarly, a jet engine as it name suggests, emits a jet used to propel rockets, aircraft, jetboats, and submarines.
