Free fall

In Newtonian physics, free fall is any motion of a body where gravity is the only force acting upon it. In the context of general relativity, where gravitation is reduced to a space-time curvature, a body in free fall has no force acting on it and moves along a geodesic. The present article only concerns itself with free fall in the Newtonian domain.

An object in the technical sense of free fall may not necessarily be falling down in the usual sense of the term. An object moving upwards would not normally be considered to be falling, but if it is subject to the force of gravity only, it is said to be in free fall. The moon is thus in free fall.

In a uniform gravitational field, in the absence of any other forces, gravitation acts on each part of the body equally and this is weightlessness, a condition that also occurs when the gravitational field is zero (such as when far away from any gravitating body). A body in free fall experiences "0 g".

The term "free fall" is often used more loosely than in the strict sense defined above. Thus, falling through an atmosphere without a deployed parachute, or lifting device, is also often referred to as free fall. The aerodynamic drag forces in such situations prevent them from producing full weightlessness, and thus a skydiver's "free fall" after reaching terminal velocity produces the sensation of the body's weight being supported on a cushion of air.

Freefall (1994 film)

Freefall is a 1994 action film starring Eric Roberts, Jeff Fahey and Pamela Gidley. It is directed by John Irvin, written and produced by David Zito and Les Weldon.

The story tells about undercover INTERPOL agent Grant Orion (Roberts), who, after recently being falsely accused of a crime, attempts to prove his innocence to wildlife photographer Katy Mazur (Gidley) while rescuing her from an assassin organisation led by her fiancé Dex Dellum (Fahey).

Originally intended for a theatrical release, the movie was released straight to VHS in the United States by Vidmark Entertainment and in Canada that same year by Cineplex Odeon. In 2002, Platinum Disc released a DVD of the film.

Charles "Nish" Bruce

Sergeant Charles Christian Cameron "Nish" Bruce QGM (8 August 1956 – 8 January 2002) was a former British Army soldier and freefall expert of high altitude military parachuting who served in 22 (SAS) Special Air Service (1982–88). He served with the 22 SAS in the Falklands War, on anti-drug operations in South and Central America and in Northern Ireland during Operation Banner for which he was awarded the Queen's Gallantry Medal in 1986.

He received the South Atlantic Medal in 1982 with B Squadron of the 22 Special Air Service and the General Service Medal with the 2nd Battalion, Parachute Regiment for services in Northern Ireland during The Troubles.

Family & Early Life

Bruce was born in Chipping Norton in 1956, middle son of Ewen Anthony Guy Cameron Bruce. He was the paternal grandson of Major Ewen Cameron Bruce (of Blaen-y-cwm).

Military career

Bruce joined the Parachute Regiment in 1973 at age 17 and in 1978 spent 4 years with The Red Devils Display Team participating in test jumping, international exhibitions and competitions before passing SAS selection and joining 22 SAS in April 1982.

Witches (Marvel Comics)

Witches is a supernatural comic book limited series that was published by Marvel Comics in 2004. Plotted by Bronwyn Carlton, with scripts by Brian Walsh, it featured art by Mike Deodato and Will Conrad.

Publication history

Marvel Comics originally green-lit this storyline in late 2000 and released promotional art for the series in 2001 at both Comic-Con International (Marvel: 2001 Official Convention Preview Book, pages 18–19) and various comic book based websites. According to those original website advertisements, Marvel had planned on releasing the series (then titled The Way of the Witches) during the last week of September 2001. Marvel Comics had planned to capitalize on the female-based television shows and movies that were popular at the time such as Charmed, Buffy the Vampire Slayer, and Charlie's Angels with a comic book title of their own. The three characters decided upon were mostly unused magical female characters in their universe: Jennifer Kale from the Man-Thing comic, Topaz from the Werewolf by Night comic, and Satana - the Devil's Daughter - from several of Marvel's horror comics, primarily Son of Satan, The Haunt of Horror and Vampire Tales. They were to be led by the most recognizable Marvel comic-book sorcerer, Doctor Strange, with him acting as the Charlie's Angels-esque director. Aside from the main characters, other supernatural characters that were to have appeared in the series (according to artist Mike Deodato) included: Werewolf by Night, Man-Thing, Ghost Rider, Lilith (the vampire), Lilith (the demon), Moon Knight, Blade, and Daimon Hellstrom.

Witches (Discworld)

A major subset of the Discworld novels of Terry Pratchett involves the witches of Lancre. They are closely based on witches in British folklore and a slightly tongue-in-cheek reinterpretation of the Triple Goddess.

Overview

Witch magic is very different from the wizard magic taught in the Unseen University, and consists largely of finding the right lever that makes everything else work. Witches rarely do any magic, in fact, relying more on common sense, hard work, and a peculiar brand of psychology known as headology. This can be taken very far - a witch's way of magically setting fire to a log of wood consists of staring at the log until it burns up from pure embarrassment. As a result, it is less energy-intensive, which means that a witch can do more than a technically equally powerful wizard. The same zen-like knowledge that gives them this ability generally discourages them from making a big deal about it, beyond refusing to take wizards seriously. Headology is more commonly used on people, like the placebo effect. Witches unironically acting with melodrama, of which cackling is an early sign, is often an indication of "going to the bad" and becoming a stereotypically wicked witch.

Eternal Light (video game)

Eternal Light (formerly titled Witches) is a third-person combat game developed by Revistronic. It began development in 2005 but was ultimately cancelled in 2011 when Revistronic went bankrupt. The game was planned for release on PlayStation 3, Xbox 360, and Microsoft Windows.

The developers described the game as taking place in a dark medieval setting in which the player must fight hordes of demons as protagonists Tempest, Fire, and Shadow. They also stated that cooperative gameplay would be an essential game mechanic. On February 25, 2008, Revistronic released a teaser website with several screenshots and a trailer video.
