Levitation

Levitation (from Latin levitas "lightness") is the process by which an object is held aloft, without mechanical support, in a stable position.

Levitation is accomplished by providing an upward force that counteracts the pull of gravity (in relation to gravity on earth), plus a smaller stabilizing force that pushes the object toward a home position whenever it is a small distance away from that home position. The force can be a fundamental force such as magnetic or electrostatic, or it can be a reactive force such as optical, buoyant, aerodynamic, or hydrodynamic.

Levitation excludes floating at the surface of a liquid because the liquid provides direct mechanical support. Levitation excludes hovering flight by insects, hummingbirds, helicopters, rockets, and balloons because the object provides its own counter-gravity force.

Physics

Levitation (on Earth or any planetoid) requires an upward force that cancels out the weight of the object, so that the object does not fall (accelerate downward) or rise (accelerate upward). For positional stability, any small displacement of the levitating object must result in a small change in force in the opposite direction. The small changes in force can be accomplished by gradient field(s) or by active regulation. If the object is disturbed, it might oscillate around its final position, but its motion eventually decreases to zero due to damping effects. (In a turbulent flow, the object might oscillate indefinitely.)

Levitation (festival)

Levitation (formerly Austin Psych Fest) is an annual 3-day music festival developed and produced by The Reverberation Appreciation Society. Since its first year in 2008 it has been held at Carson Creek in Austin, Texas. Inspired by the creative explosion of the 1960s, as well as by festivals such as ATP and Primavera Sound, they set out to create their vision of a music festival.

Over the years, this independent festival has grown to an internationally acclaimed, full weekend event that attracts attendees from all over the world. In 2015 Austin Psych Fest was renamed LEVITATION in honor of Austin’s legendary psychedelic rock godfathers The 13th Floor Elevators.

The Reverberation Appreciation Society is a creative collective composed of Rob Fitzpatrick, Oswald James, and Christian Bland and Alex Maas of The Black Angels. In addition to the festival in Austin, the group has branched out into other cities beginning in 2013 with Levitation France and in 2015 with Levitation Vancouver and Levitation Chicago. The group also runs a record label and presents events at Austin’s SXSW, The Netherlands’ Le Guess Who, NYC’s CMJ and NRMAL in Mexico City.

Levitation (band)

Levitation were an English psychedelic rock band, formed in 1990 in London. The band consisted of frontman Terry Bickers (formerly guitarist with The House of Love), drummer David Francolini, guitarist Christian Hayes, bassist Laurence O'Keefe and keyboardist Robert White.

Bickers announced his departure from the band onstage at Tufnell Park Dome in north London on 14 May 1993. The release of the band's already completed second album Meanwhile Gardens was shelved. The band enlisted former Some Have Fins frontman Steve Ludwin to replace Bickers, which saw a remixed version of the album with new vocals from Ludwin released in Australia the following year. The band split in October 1994, leaving their second album remaining unreleased. Hayes, Francolini and O'Keefe regrouped in 1996 to form Dark Star. They released Twenty Twenty Sound in 1999 before disbanding in 2001.

History

Formation & Early EPs

Following his departure from The House Of Love in 1990, Terry Bickers began forming a new band with drummer David Francolini. The pair met during Bickers' last tour with his previous band in December 1989, on which Francolini was playing with support band Something Pretty Beautiful whom he joined just days before going out on tour. They first enlisted Christian Hayes, who had played with Ring and Panixphere, played bass in The Dave Howard Singers and was currently playing guitar in Cardiacs and working as a courier. Bickers knew Hayes through musical friends in South London, and when Bickers and Francolini spotted Hayes on his courier bike by chance in Covent Garden, London they arranged to meet up in the studio. Hayes' former Ring bandmate, keyboardist Robert White (also formerly of Zag and the Coloured Beads) soon joined along with bassist Joe Allen and violinist Johnny T, a member of The Reggae Philharmonic Orchestra.

Natas (computer virus)

Natas (Satan spelled backwards) is a computer virus written by James Gentile, a then-18-year-old hacker from San Diego, California who went by the alias of "Little Loc" and later "Priest". The virus was made for a Mexican politician who wanted to win the Mexican elections by affecting all the Mexican Federal Electoral Institute (IFE) computers with a floppy disk.

Description

Natas is a memory-resident stealth virus and is highly polymorphic, that affects master boot records, boot sectors of diskettes, files .COM and also .exe programs.

History

The virus first appeared in Mexico City in May 1992, spread by a consultant using infected floppy disks. The virus became widespread in Mexico and the southwest United States. The virus also made its way to the other side of the USA, infecting computers at the United States Secret Service knocking their network offline for approximately three days. This led to an investigation of Priest and incorrect suspicion that the virus specifically targeted government computers.

Natas (group)

HIDDEN ERROR: Usage of "members" is not recognized

Natas (Nation Ahead of Time And Space, originally Niggas Ahead of Time And Space) is an American hip hop group from Detroit, Michigan. Their last studio album "N of tha World" was released in 2006 through Warlock/Sony Red. In 2009, they released the mixtape "The Vatican". Currently original members Esham, TNT and Mastamind are recording a reunion album according to Mastamind's official Facebook account.

History

Esham met Mastamind as a student at Osborne High School, who gave him a three-song demo tape of his music, leading the two to form the group with Esham's longtime friend, T-N-T, deciding on the name Natas, an acronym for "Nation Ahead of Time And Space", and because it was "Satan" spelled backwards. In 1992, Natas released its first album, Life After Death on Esham's Reel Life Productions. Following the release of this album, Esham, Natas and Reel Life Productions were the subject of much controversy when a 17-year-old fan killed himself while smoking cannabis and playing Russian roulette while listening to Life After Death.
