A slipstream is a region behind a moving object in which a wake of fluid (typically air or water) is moving at velocities comparable to the moving object, relative to the ambient fluid through which the object is moving. The term slipstream also applies to the similar region adjacent to an object with a fluid moving around it. "Slipstreaming" or "drafting" works because of the relative motion of the fluid in the slipstream.

A slipstream created by turbulent flow has a slightly lower pressure than the ambient fluid around the object. When the flow is laminar, the pressure behind the object is higher than the surrounding fluid.

The shape of an object determines how strong the effect is. In general, the more aerodynamic an object is, the smaller and weaker its slipstream will be. For example, a box-like front (relative to the object's motion) will collide with the medium's particles at a high rate, transferring more momentum from the object to the fluid than a more aerodynamic object. A bullet-like profile will cause less turbulence and create a more laminar flow.

Slipstream is a 2005 science fiction film, written by Louis Morneau and Phillip Badger and directed by David van Eyssen. The film stars Sean Astin, Vinnie Jones, and Ivana Miličević. It was first shown at the London Sci-Fi and Fantasy Film Festival on February 3, 2005. The film concerns the efforts of a socially inept scientist (Sean Astin) and a female FBI agent (Ivana Miličević) to recover a time travel device (called "Slipstream") that was stolen by a group of bank robbers commanded by Vinnie Jones. The film was imagined as part science fiction, part action and part buddy comedy.

Plot

Stuart Conway (Sean Astin) has developed a hand-held, cellphone-like time travel device called 'Slipstream' that allows the user to travel back in time 10 minutes by interfacing with a cellphone system regional antenna. At first, he uses the device primarily to try, albeit unsuccessfully, to arrange a date with a female bank clerk.

The final time he tries to use the device, a group of bank robbers commanded by Winston Briggs (Vinnie Jones) rush into the bank and demand the money from the vault. At the time, FBI agent Sarah Tanner (Ivana Miličević) and her male partner Jake (Kevin Otto) are in the bank tracking Stuart. Tanner initiates a gunfight against Jake's advice. Both agents are armed with pistols, while the criminals are wielding automatic weapons. By the end of the fight, Jake is shot and killed because he chased the criminals outside the bank.

Slipstream is a kind of fantastic or non-realistic fiction that crosses conventional genre boundaries between science fiction, fantasy, and literary fiction.

The term slipstream was coined by cyberpunk author Bruce Sterling in an article originally published in SF Eye #5, in July 1989. He wrote: "...this is a kind of writing which simply makes you feel very strange; the way that living in the twentieth century makes you feel, if you are a person of a certain sensibility." Slipstream fiction has consequently been described as "the fiction of strangeness," which is as clear a definition as any of the others in wide use. Science fiction authors James Patrick Kelly and John Kessel, editors of Feeling Very Strange: The Slipstream Anthology, argue that cognitive dissonance is at the heart of slipstream, and that it is not so much a genre as a literary effect, like horror or comedy.

Slipstream falls between speculative fiction and mainstream fiction. While some slipstream novels employ elements of science fiction or fantasy, not all do. The common unifying factor of these pieces of literature is some degree of the surreal, the not-entirely-real, or the markedly anti-real.

Denon (株式会社デノン, Kabushiki Kaisha Denon) is a Japanese electronics company that was involved in the early stages of development of digital audio technology, while specializing in the manufacture of high-fidelity professional and consumer audio equipment. For many decades, Denon was a brand name of Nippon-Columbia, including the Nippon Columbia record label. In 2001 Denon was spun off as a separate company with 98% held by Ripplewood Holdings and 2% by Hitachi. In 2002 Denon merged with Marantz to form D&M Holdings. The Denon brand came from a merger of Denki Onkyo and others in 1939.

History

The company was originally established in 1910 as part of Nippon Chikuonki Shokai (Japan Recorders Corporation), a manufacturer of single-sided disc records and gramophones. The company was originally called 日本電氣音響株式會社 - Nippon 'DENki ONkyo Kabushikigaisha' which was shortened to the name of DEN-ON in Japanese. The company is actively involved with sound systems electric appliance production and later the company has been merged with other related companies as a result of this the company name became Denon.
