Recoil

Recoil (often called knockback, kickback or simply kick) is the backward momentum of a gun when it is discharged. In technical terms, the recoil caused by the gun exactly balances the forward momentum of the projectile and exhaust gases (ejecta), according to Newton's third law. In most small arms, the momentum is transferred to the ground through the body of the shooter; while in heavier guns such as mounted machine guns or cannons, the momentum is transferred to the ground through its mount. In order to bring the gun to a halt, a forward counter-recoil force must be applied to the gun over a period of time. Generally, the counter-recoil force is smaller than the recoil force, and is applied over a time period that is longer than the time that the recoil force is being applied (i.e. the time during which the ejecta are still in the barrel of the gun). This imbalance of forces causes the gun to move backward until it is motionless.

A change in momentum results in a force, which according to Newton's second law is equal to the time derivative of the momentum of the gun. The momentum is equal to the mass of the gun multiplied by its velocity. This backward momentum is equal in magnitude, by the law of conservation of momentum, to the forward momentum of the ejecta (projectile(s), wad, propellant gases, etc...) from the gun. If the mass and velocity of the ejecta are known, it is possible to calculate a gun’s momentum and thus the energy. In practice, it is often simpler to derive the gun’s energy directly with a reading from a ballistic pendulum or ballistic chronograph.

Prey (novel)

Prey is a novel by Michael Crichton, first published in November 2002. An excerpt was published in the January–February 2003 issue of Seed. Like Jurassic Park, the novel serves as a cautionary tale about developments in science and technology; in this case, nanotechnology, genetic engineering and artificial intelligence.

The book features relatively new advances in the computing/scientific community, such as artificial life, emergence (and by extension, complexity), genetic algorithms, and agent-based computing.

While the novel has yet to be adapted into a movie, film rights to the novel were purchased by 20th Century Fox.

Plot summary

The novel is narrated by the protagonist Jack Forman, who is an unemployed software programmer who used to work for a company called Media Tronics but was fired for discovering an internal scandal. As a result, he is forced to take the role of a house husband while his wife Julia serves as a high ranking employee at a nanorobotics company called Xymos. Julia claims that she is working on a new piece of revolutionary imaging technology with her company, which takes up most of her time and makes her grow distant to Jack and her family. He starts believing that during her long hours away from home she is having an affair, and becomes watchful of her changes.

Prey (Star Trek: Voyager)

"Prey" is the 84th episode of the science fiction television series Star Trek: Voyager, the 16th episode of the fourth season.

Overview: A member of Species 8472 captured by the Hirogen penetrates Voyager.

Plot

The Federation starship Voyager discovers an injured Hirogen who is in the middle of an intense hunt for what is a formidable and dangerous prey even for Hirogen standards. He is brought in to Sickbay for treatment, but is eager to get back out and track down his trophy prey. Before he is able to do so, the prey alien invades Voyager. It is a tough, armored, telepathic, insectlike creature that the Borg have designated Species 8472.

The Hirogen hunter is allowed to hunt for 8472 under Chakotay's supervision. The Hirogen starts attacking an unresponsive 8472 without hesitation. He refuses an order to stand down and battles with his Starfleet escort before being stunned and subdued; he is subsequently confined in sickbay. As the crew later approach the seriously injured 8472, it telepathically communicates with the Vulcan tactical officer Tuvok, pleading to be rescued from the hunter and returned to its home, which is a different dimension known as "fluidic space." Meanwhile, a number of Hirogen vessels surround Voyager threatening to destroy them unless 8472 is beamed over. Nevertheless, Captain Janeway immediately orders Seven of Nine to help the alien return to its home territory, hoping to open the door to peaceful contact with its species. Seven refuses to comply, believing the protection of the hated and feared alien is not worth facing imminent destruction at the hands of the Hirogen. She informs Janeway that the approaching Hirogen ships will destroy Voyager unless 8472 is turned over, and a lesson in compassion will do her no good if she is dead.

Prey (miniseries)

Prey is a television crime thriller first broadcast on ITV, 28 April 2014 at 9pm. ITV first announced the new commission on their official Twitter account on 23 August 2013. A second series was announced in April 2015 and began airing on 9 December 2015.
