Star Trek is an American science fiction entertainment franchise created by Gene Roddenberry and under the ownership of CBS and Paramount.[Note 1] Star Trek: The Original Series and its live action TV spin-off shows, Star Trek: The Next Generation, Star Trek: Deep Space Nine, Star Trek: Voyager, and Star Trek: Enterprise as well as the Star Trek film series make up the main canon. Star Trek: The Animated Series is debated and the expansive library of Star Trek novels and comics, although still part of the franchise, are generally considered non-canon.[Note 2]

The first series, now referred to as "The Original Series", debuted in 1966 and ran for three seasons on NBC. It followed the interstellar adventures of James T. Kirk and the crew of the starship Enterprise, an exploration vessel of a 23rd-century interstellar "United Federation of Planets". In creating the first "Star Trek", Roddenberry was inspired by Westerns such as Wagon Train, along with the Horatio Hornblower novels and Gulliver's Travels. In fact, the original show was almost entitled, 'Wagon Train to the Stars.' These adventures continued in the short-lived Star Trek: The Animated Series and six feature films. Four spin-off television series were eventually produced: Star Trek: The Next Generation, followed the crew of a new starship Enterprise set a century after the original series; Star Trek: Deep Space Nine and Star Trek: Voyager, set contemporaneously with The Next Generation; and Star Trek: Enterprise, set before the original series, in the early days of human interstellar travel. Four additional The Next Generation feature films were produced. In 2009, the film franchise underwent a relaunch with a prequel to the original series set in an alternate timeline titled simply Star Trek. This film featured a new cast portraying younger versions of the crew from the original Enterprise.[Note 3] A sequel to this film, Star Trek Into Darkness, premiered on May 16, 2013. A thirteenth theatrical feature, the next sequel to Into Darkness, has been confirmed for release
in July 2016, to coincide with the franchise's 50th anniversary.

Star Trek has been a cult phenomenon for decades.[1] Fans of the franchise are called Trekkies or Trekkers. The franchise spans a wide range of spin-offs including games, figurines, novels, toys, and comics. Star Trek had a themed attraction in Las Vegas that opened in 1998 and closed in September 2008. At least two museum exhibits of props travel the world. The series has its own full-fledged constructed language, Klingon. Several parodies have been made of Star Trek. Its fans, despite the end of Star Trek episodes on TV, have produced several fan productions to fill that void.

Star Trek is noted for its influence on the world outside of science fiction. It has been cited as an inspiration for several technological inventions such as the cell phone. Moreover, the show is noted for its progressive for its era civil rights stances. The original series included one of television's first multiracial casts. Star Trek references can be found throughout popular culture from movies such as the submarine thriller Crimson Tide to the cartoon series South Park.

Conception and setting

As early as 1964, Gene Roddenberry drafted a proposal for the science fiction series that would become Star Trek. Although he publicly marketed it as a Western in outer space—a so-called "Wagon Train to the Stars" (like the popular Western TV series)[2]—he privately told friends that he was modeling it on Jonathan Swift's Gulliver's Travels, intending each episode to act on two levels: as a suspenseful adventure story and as a morality tale.[3]

Most Star Trek stories depict the adventures of humans[Note 4] and aliens who serve in Starfleet, the space-borne humanitarian and peacekeeping armada of the United Federation of Planets. The protagonists have altruistic values, and must apply these ideals to difficult dilemmas. Many of the conflicts and political dimensions of Star Trek represent allegories of contemporary cultural realities. Star Trek: The Original Series addressed issues of the 1960s,[4] just as later spin-offs have reflected issues of their respective decades. Issues depicted in the various series include war and peace, the value of personal loyalty, authoritarianism, imperialism, class warfare, economics, racism, religion, human rights, sexism, feminism, and the role of technology.[5] Roddenberry stated: "[By creating] a new world with new rules, I could make statements about sex, religion, Vietnam, politics, and intercontinental missiles. Indeed, we did make them on Star Trek: we were sending messages and fortunately they all got by the network."[6]

Roddenberry intended the show to have a progressive political agenda reflective of the emerging counter-culture of the youth movement, though he was not fully forthcoming to the networks about this. He wanted Star Trek to show humanity what it might develop into, if only it would learn from the lessons of the past, most specifically by ending violence. An extreme example is the alien species, the Vulcans, who had a violent past but learned to control their emotions. Roddenberry also gave Star Trek an anti-war message and depicted the United Federation of Planets as an ideal, optimistic version of the United Nations.[7] His efforts were opposed by the network because of concerns over marketability, e.g., they opposed Roddenberry's insistence that the Enterprise have a racially diverse crew.[8]

However, Star Trek has also been accused of evincing racism and imperialism by frequently depicting Starfleet and the Federation trying to impose their values and customs on other planets.[9][10]

Beginnings


Star Trek creator, producer and writer Gene Roddenberry

Captain James T. Kirk and Commander Spock, played by William Shatner and Leonard Nimoy, pictured here in The Original Series.

In early 1964, Roddenberry presented a brief treatment for a proposed Star Trek TV series to Desilu Productions comparing it to Wagon Train, "a Wagon Train to the stars."[11] Desilu worked with Roddenberry to develop the treatment into a script, which was then pitched to NBC.[12]

NBC paid to make a pilot, "The Cage", starring Jeffrey Hunter as Enterprise Captain Christopher Pike. NBC rejected The Cage, but the executives were still impressed with the concept, and made the unusual decision to commission a second pilot: "Where No Man Has Gone Before".[12]

The first regular episode ("The Man Trap") of Star Trek: The Original Series aired on Thursday, September 8, 1966.[13] While the show initially enjoyed high ratings, the average rating of the show at the end of its first season dropped to 52nd (out of 94 programs).

Unhappy with the show's ratings, NBC threatened to cancel the show during its second season.[14] The show's fan base, led by Bjo Trimble, conducted an unprecedented letter-writing campaign, petitioning the network to keep the show on the air.[15][16] NBC renewed the show, but moved it from primetime to the "Friday night death slot", and substantially reduced its budget.[17] In protest Roddenberry resigned as producer and reduced his direct involvement in Star Trek, which led to Fred Freiberger becoming producer for the show's third and final season.[Note 5] Despite another letter-writing campaign, NBC cancelled the series after three seasons and 79 episodes.[12]

Rebirth

After the original series was cancelled, Paramount Studios, which had bought the series from Desilu, licensed the broadcast syndication rights to help recoup the production losses. Reruns began in the fall of 1969 and by the late 1970s the series aired in over 150 domestic and 60 international markets.
This helped Star Trek develop a cult following greater than its popularity during its original run.[18]

One sign of the series' growing popularity was the first Star Trek convention which occurred on January 21–23, 1972 in New York City. Although the original estimate of attendees was only a few hundred, several thousand fans turned up. Star Trek fans continue to attend similar conventions worldwide.[19]

The series' newfound success led to the idea of reviving the franchise.[20] Filmation with Paramount Television produced the first post original series show, Star Trek: The Animated Series. It ran on NBC for 22 half-hour episodes over two seasons on Saturday mornings from 1973 to 1974. Although short-lived, typical for animated productions in that time slot during that period, the series garnered the franchise's only "Best Series" Emmy Award as opposed to the franchise's later technical ones. Paramount Pictures and Roddenberry began developing a new series, Star Trek: Phase II, in May 1975 in response to the franchise's newfound popularity. However, work on the series ended when the proposed Paramount Television Service folded.

Following the success of the science fiction movies Star Wars and Close Encounters of the Third Kind, Paramount adapted the planned pilot episode of Phase II into the feature film, Star Trek: The Motion Picture. The film opened in North America on December 7, 1979, with mixed reviews from critics. The film earned $139 million worldwide, below expectations but enough for Paramount to create a sequel. The studio forced Roddenberry to relinquish creative control of future sequels.

The success of the critically acclaimed sequel, Star Trek II: The Wrath of Khan, reversed the fortunes of the franchise. While the sequel grossed less than the first movie, The Wrath of Khan '​s lower production costs made it net more profit. Paramount produced six Star Trek feature films between 1979 and 1991. In response to the popularity of Star Trek feature films, the franchise returned to television with Star Trek: The Next Generation (TNG) in 1987. Paramount chose to distribute it as a first-run syndication show rather than a network show.[21]

After Roddenberry

Following Star Trek: The Motion Picture, Roddenberry's role was changed from producer to creative consultant with minimal input to the films while being heavily involved with the creation of Star Trek: The Next Generation. Roddenberry died on October 24, 1991, giving executive producer Rick Berman control of the franchise. Star Trek had become known to those within Paramount as "the franchise", because of its great success and recurring role as a tent pole for the studio when other projects failed.[22] TNG had the highest ratings of any Star Trek series and became the #1 syndicated show during the last years of its original seven-season run.[23] In response to TNG's success, Paramount released a spin-off series Deep Space Nine in 1993. While never as popular as TNG, the series had sufficient ratings for it to last seven seasons.

In January 1995, a few months after TNG ended, Paramount released a fourth TV series, Voyager. Star Trek saturation reached a peak in the mid-1990s with DS9 and Voyager airing concurrently and three of the four TNG-based feature films released in 1994, 1996, and 1998. By 1998, Star Trek was Paramount's most important property; the enormous profits of "the franchise" funded much of the rest of the studio's operations.[24]:49–50,54 Voyager became the flagship show of the new United Paramount Network (UPN) and thus the first major network Star Trek series since the original.[25]

After Voyager ended, UPN produced Enterprise, a prequel TV series to the original show. Enterprise did not enjoy the high ratings of its predecessors and UPN threatened to cancel it after the series' third season. Fans launched a campaign reminiscent of the one that saved the third season of the Original Series. Paramount renewed Enterprise for a fourth season,[26] but moved it to the Friday night death slot.[27] Like the Original Series, Enterprise ratings dropped during this time slot, and UPN cancelled Enterprise at the end of its fourth season. Enterprise aired its final episode on May 13, 2005.[28] Fan groups, such as "Save Enterprise", attempted to save the series[29] and tried to raise $30 million to privately finance a fifth season of Enterprise.[29] Though the effort garnered considerable press, the fan drive failed to save the series. The cancellation of Enterprise ended an eighteen-year continuous production run of Star Trek programming on television. The poor box office performance in 2002 of the film Nemesis, cast an uncertain light upon the future of the franchise. Paramount relieved Berman, the franchise producer, of control of Star Trek.

Reboot

Paramount turned down several proposals in the mid-2000s to restart the franchise. These included pitches from film director Bryan Singer,[30] Babylon 5 creator J. Michael Straczynski,[31] and Trek actors Jonathan Frakes and William Shatner.[32] The studio also turned down an animated web series.[33] Instead, Paramount hired a new creative team to reinvigorate the franchise in 2007. Writers Roberto Orci and Alex Kurtzman and Lost producer, J. J. Abrams, had the freedom to reinvent the feel of Trek.

The team created the franchise's eleventh film, titled simply Star Trek, releasing it in May 2009. The film featured a new cast portraying the crew of the original Enterprise. Star Trek was a prequel of the original series set in an alternate timeline. This gave the film and future sequels to it freedom from the need to conform to the franchise's canonical timeline. The eleventh Star Trek film's marketing campaign targeted non-fans, even stating in the film's advertisements that "this is not your father's Star Trek".[34]

The film earned considerable critical and financial success, grossing in inflation-adjusted dollars more box office sales than any previous Star Trek film.[35] The plaudits include the franchise's first Academy Award (for makeup). The film's major cast members are contracted for two sequels.[36] Paramount's sequel to the 2009 film, Star Trek Into Darkness, premiered in Sydney, Australia on April 23, 2013, however the movie did not release in the United States until May 17, 2013.[37] While the film was not as successful in the North American box office as its predecessor, internationally, in terms of box office receipts, Into Darkness was the most successful of the franchise.[38] A thirteenth Star Trek film is scheduled to be released on July 8, 2016.[39]

Television series

Six television series make up the bulk of the Star Trek mythos: The Original Series, The Animated Series, The Next Generation, Deep Space Nine, Voyager, and Enterprise. All the different versions in total amount to 726 Star Trek episodes across the 30 seasons of the TV series.[Note 6]

The Original Series (1966–69)

William Shatner played the unflappable Captain James T. Kirk in The Original Series, The Animated Series, and seven films, helping to create the standard for all subsequent fictional Starfleet captains.

Star Trek: The Original Series or "TOS"[Note 7] debuted in the United States on NBC on September 8, 1966.[40] The show tells the tale of the crew of the starship Enterprise and its five-year mission "to boldly go where no man has gone before." The original 1966–1969 television series featured William Shatner as Captain James T. Kirk, Leonard Nimoy as Spock, DeForest Kelley as Dr. Leonard "Bones" McCoy, James Doohan as Montgomery "Scotty" Scott, Nichelle Nichols as Uhura, George Takei as Hikaru Sulu, and Walter Koenig as Pavel Chekov. During the series' original run, it earned several nominations for the Hugo Award for Best Dramatic Presentation and won twice: for the two-parter "The Menagerie" and the Harlan Ellison-written episode "The City on the Edge of Forever".

After three seasons, NBC canceled the show, and the last original episode aired on June 3, 1969.[41] However, the petition near the end of the second season to save the show signed by many Caltech students and its multiple Hugo nominations would indicate that despite low Nielsen ratings, it was highly popular with science fiction fans and engineering students. The series later became popular in reruns and found a cult following.[40]

The Animated Series (1973–74)


The Animated Series logo

Star Trek: The Animated Series, produced by Filmation, ran for two seasons from 1973 to 1974. Most of the original cast performed the voices of their characters from The Original Series, and many of the original series' writers, such as D. C. Fontana, David Gerrold, and Paul Schneider, wrote for the series. While the animated format allowed the producers to create more exotic alien landscapes and life forms, animation errors, and liberal reuse of shots and musical cues have tarnished the series' reputation.[42] Although it was originally sanctioned by Paramount, which owned the Star Trek franchise following its acquisition of Desilu in 1967, Gene Roddenberry often spoke of TAS as non canon.[43] Star Trek writers have used elements of the animated series in later live-action series and movies, and as of June 2007, the Animated Series has references in the library section of the official Startrek.com web site.

TAS won Star Trek '​s first Emmy Award on May 15, 1975.[44] Star Trek TAS briefly returned to television in the mid-1980s on the children's cable network Nickelodeon. Nickelodeon's Evan McGuire greatly admired the show and used its various creative components as inspiration for his short series called Piggly Wiggly Hears A Sound which never aired. Nickelodeon parent Viacom would purchase Paramount in 1994. In the early 1990s, the Sci-Fi Channel also began rerunning TAS. The complete TAS was also released on Laserdisc format during the 1980s.[45] The complete series was first released in the USA on eleven volumes of VHS tapes in 1989. All 22 episodes were released on DVD in 2006.

The Next Generation (1987–1994)

Star Trek: The Next Generation, also known as "TNG", takes place about a century after The Original Series (2364–2370). It features a new starship, the Enterprise-D, and a new crew led by Captain Jean-Luc Picard (Patrick Stewart) and Commander William Riker (Jonathan Frakes). Some crewmembers represent new alien races, including Deanna Troi, a half-Betazoid counselor played by Marina Sirtis. Michael Dorn plays Worf, the first Klingon officer in Starfleet, alongside Gates McFadden as Dr. Beverly Crusher, LeVar Burton as chief engineer Geordi La Forge, the android Data portrayed by Brent Spiner, and Dr. Crusher's son Wesley Crusher played by Wil Wheaton. The show premiered on September 28, 1987, and ran for seven seasons, ending on May 23, 1994.[46] It had the highest ratings of any of the Star Trek series and became the #1 syndicated show during the last few years of its original run, allowing it to act as a springboard for ideas in other series. Many relationships and races introduced in TNG became the basis of episodes in Deep Space 9 and Voyager.[23] During its run it earned several Emmy awards and nominations – including a nomination for Best Dramatic Series during its final season – two Hugo Awards, and a Peabody Award for Outstanding Television Programming for the episode "The Big Goodbye".[47]

Deep Space Nine (1993–99)


The Deep Space Nine logo

Avery Brooks played Captain Benjamin Sisko in Deep Space Nine, commander of the titular space station and Emissary of the Prophets.

Star Trek: Deep Space Nine, also known as "DS9", takes place during the last years and the immediate post-years of The Next Generation (2369–2375) and aired for seven seasons, debuting the week of January 3, 1993.[48] Like Star Trek: The Next Generation, it aired in syndication in the United States and Canada. Unlike the other Star Trek series, DS9 takes place primarily on a space station rather than aboard a starship.

The show begins after the brutal Cardassian occupation of the planet Bajor. The liberated Bajoran people ask the United Federation of Planets to help run a Cardassian built space station, Deep Space Nine, near Bajor. After the Federation takes control of the station, the protagonists of the show discover a uniquely stable wormhole that provides immediate access to the distant Gamma Quadrant making Bajor and the station one of the most strategically important locations in the galaxy.[49] The show chronicles the events of the station's crew, led by Commander (later Captain) Benjamin Sisko, played by Avery Brooks, and Major (later Colonel) Kira Nerys, played by Nana Visitor. Recurring plot elements include the repercussions of the Cardassian occupation of Bajor, Sisko's spiritual role for the Bajorans as the Emissary of the Prophets, and in later seasons a war with the Dominion.

Deep Space Nine stands apart from earlier Trek series for its lengthy serialized storytelling, conflict within the crew, and religious themes—all elements that critics and audiences praised but Roddenberry forbade in the original series and The Next Generation.[50] Nevertheless, he was informed before his death of DS9, making this the last Star Trek series connected to Gene Roddenberry.[51]

Voyager (1995–2001)


The Voyager logo

Kate Mulgrew, who played Captain Kathryn Janeway, the lead character in Voyager, and the first female commanding officer in a leading role of a Star Trek series.

Star Trek: Voyager ran for seven seasons, airing from January 16, 1995, to May 23, 2001, launching a new Paramount-owned television network UPN. It features Kate Mulgrew as Captain Kathryn Janeway,[52] the first female commanding officer in a leading role of a Star Trek series, and Commander Chakotay, played by Robert Beltran. Voyager takes place at about the same time period as Deep Space Nine and the years following that show's end (2371–2378). The premiere episode has the USS Voyager and its crew pursue a Maquis (Federation rebels) ship. Both ships become stranded in the Delta Quadrant about 70,000 light years from Earth.[53] Faced with a 75-year voyage to Earth, the crew must learn to work together to overcome challenges on their long and perilous journey home while also seeking ways to shorten the voyage. Like Deep Space Nine, early seasons of Voyager feature more conflict between its crewmembers than seen in later episodes. Such conflict often arises from friction between "by-the-book" Starfleet crew and rebellious Maquis fugitives forced by circumstance to work together on Voyager. Eventually, though, they settle their differences, after which the overall tone becomes more reminiscent of The Original Series. The starship Voyager, isolated from its home, faces new cultures and dilemmas not possible in shows based in the Alpha Quadrant. Later seasons, however, brought an influx of characters and cultures from prior shows, such as the Borg, Q, the Ferengi, Romulans, Klingons, Cardassians and cast members of The Next Generation.

Enterprise (2001–05)


The Enterprise logo. The show originally did not include "Star Trek" in its name and logo, adding it later on in the show's run.

Science fiction veteran Scott Bakula played Captain Jonathan Archer, the lead character in Enterprise, a prequel to the original show.

Star Trek: Enterprise, originally titled Enterprise, is a prequel to the original Star Trek series. It aired from September 26, 2001 to May 13, 2005.[54] Enterprise takes place in the 2150s, some 90 years after the events of Zefram Cochrane's first warp flight and about a decade before the founding of the Federation. The show centers on the voyages of Earth's first warp-five capable starship, the Enterprise, commanded by Captain Jonathan Archer (played by Scott Bakula), and the Vulcan Sub-Commander T'Pol (played by Jolene Blalock).

During the show's first two seasons, Enterprise featured self-contained episodes, like The Original Series, The Next Generation and Voyager. The third season consisted of one arc, "Xindi mission", which had the darker tone and serialized nature of Deep Space 9. Season 4 consisted of several two to three episode mini-arcs. The final season showed the origins of elements seen in earlier series, and it rectified and resolved some core continuity problems between the various Star Trek series. Ratings for Enterprise started strong but declined rapidly. Although critics received the fourth season well, both fans and the cast reviled the series finale, partly because of the episode's focus on the guest appearance of members of The Next Generation cast.[55] The cancellation of Enterprise ended an 18-year run of back-to-back new Star Trek shows beginning with The Next Generation in 1987.

Feature films

Paramount Pictures has produced twelve Star Trek feature films, the most recent being released in May 2013.[56] The first six films continue the adventures of the cast of The Original Series; the seventh film, Generations was designed as a transition from that cast to The Next Generation television series; the next three films, 8–10, focused completely on the Next Generation cast.[Note 8] The eleventh and twelfth films take place in an alternate timeline from rest of the franchise set with a new cast playing the original series characters, and with Leonard Nimoy as an elderly Spock providing a physical link to the original timeline.

Merchandise

Many licensed products are based on the Star Trek franchise. Merchandising is very lucrative for both studio and actors; by 1986 Nimoy had earned more than $500,000 from royalties.[57] Products include novels, comic books, video games, and other materials, which are generally considered non-canon.

Books

Since 1967, hundreds of original novels, short stories, and television and movie adaptations have been published. The first original Star Trek novel was Mission to Horatius by Mack Reynolds, which was published in hardcover by Whitman Books in 1968.
The first publisher of Star Trek fiction aimed at adult readers was Bantam Books. In 1970, James Blish wrote the first original Star Trek novel published by Bantam, Spock Must Die!. Pocket Books is the publisher of Star Trek novels.

Prolific Star Trek novelists include Peter David, Diane Carey, Keith R. A. DeCandido, J. M. Dillard, Diane Duane, Michael Jan Friedman, and Judith and Garfield Reeves-Stevens. Several actors and writers from the television series have also written books: William Shatner, and John de Lancie, Andrew J. Robinson, J. G. Hertzler, and Armin Shimerman have written or co-written books featuring their respective characters. Voyager producer Jeri Taylor wrote two novels featuring back story for Voyager characters, and screen authors David Gerrold, D. C. Fontana, and Melinda Snodgrass have penned books, as well.

A scholarly book published by Springer Science+Business Media in 2014 discusses the actualization of Star Trek's holodeck in the future by making extensive use of artificial intelligence and cyborgs.[58]

Comics

Star Trek-based comics have been published almost continuously since 1967 by several companies including: Marvel, DC, Malibu, Wildstorm, and Gold Key. Tokyopop is publishing an anthology of Next Generation-based stories presented in the style of Japanese manga.[59] As of 2006, IDW Publishing secured publishing rights to Star Trek comics[60] and published a prequel to the 2009 film, Star Trek: Countdown. In 2012 they published Volume I of Star Trek – The Newspaper Strip featuring the work of Thomas Warkentin.[61]

Games

The Star Trek franchise has numerous games in many formats. Beginning in 1967 with a board game based on the original series and continuing through today with online and DVD games, Star Trek games continue to be popular among fans.
Video games of the series include Star Trek: Legacy and Star Trek: Conquest. An MMORPG based on Star Trek called Star Trek Online was developed by Cryptic Studios and published by Perfect World. It is set in the TNG universe about 30 years after the events of Star Trek: Nemesis.[62] The most recent video game, set in the new timeline debuted in J. J. Abrams's film, was titled Star Trek.

On June 8, 2010, Wiz Kids Games, which is owned by NECA, announced that they are developing a Star Trek collectible miniatures game using the HeroClix game system.[63]

Magazines

Star Trek has led directly or indirectly to the creation of a number of magazines which focus either on science fiction or specifically on Star Trek. Starlog was a magazine which was founded in the 1970s. Initially, its focus was on Star Trek actors, but then it began to expand its scope.

In 2013, Star Trek Magazine was a significant publication from the U.K. which was sold at newsstands and also via subscription. Other magazines through the years included professional magazines as well as magazines produced by fans, referred to as "fanzines". Star Trek: The Magazine was a magazine published in the U.S. which ceased publication in 2003.

Cultural impact

Prototype space shuttle Enterprise named after the fictional starship with Star Trek television cast members and creator Gene Roddenberry.

The Star Trek media franchise is a multi-billion dollar industry, owned by CBS.[64] Gene Roddenberry sold Star Trek to NBC as a classic adventure drama; he pitched the show as "Wagon Train to the Stars" and as Horatio Hornblower in Space.[65] The opening line, "to boldly go where no man has gone before," was taken almost verbatim from a US White House booklet on space produced after the Sputnik flight in 1957.[66] The central trio of Kirk, Spock, and McCoy was modeled on classical mythological storytelling.[65]

Star Trek and its spin-offs have proven highly popular in syndication and are shown on TV stations worldwide.[67] The show's cultural impact goes far beyond its longevity and profitability. Star Trek conventions have become popular among its fans, who call themselves "trekkies" or "trekkers". An entire subculture has grown up around the show[68] which was documented in the film Trekkies. Star Trek was the highest-ranked cult show by TV Guide.[69] The franchise has also garnered many comparisons of the Star Wars franchise being rivals in the science fiction genre with many fans and scholars.[70][71][72]

The Star Trek franchise inspired some designers of technologies, such as the Palm PDA and the handheld mobile phone.[73][74] Michael Jones, Chief technologist of Google Earth, has cited the tricorder's mapping capability as one inspiration in the development of Keyhole/Google Earth.[75] The Tricorder X PRIZE, a contest to build a medical tricorder device was announced in 2012. Ten finalists have been selected in 2014, and the winner will be selected in January 2016. Star Trek also brought teleportation to popular attention with its depiction of "matter-energy transport", with the famously misquoted phrase "Beam me up, Scotty" entering the vernacular.[76] In 1976, following a letter-writing campaign, NASA named its prototype space shuttle Enterprise, after the fictional starship.[77] Later, the introductory sequence to Star Trek: Enterprise included footage of this shuttle which, along with images of a naval sailing vessel called the Enterprise, depicted the advancement of human transportation technology.

Beyond Star Trek's fictional innovations, its contributions to TV history included a multicultural and multiracial cast. While more common in subsequent years, in the 1960s it was controversial to feature an Enterprise crew that included a Japanese helmsman, a Russian navigator, a black female communications officer, and a Vulcan-Human first officer. Captain Kirk's and Lt. Uhura's kiss, in the episode "Plato's Stepchildren", was also daring, and is often mis-cited as being American television's first scripted, interracial kiss, even though several other interracial kisses predated this one.[78]

Parodies

Early TV comedy sketch parodies of Star Trek included a famous sketch on Saturday Night Live titled "The Last Voyage of the Starship Enterprise", with John Belushi as Kirk, Chevy Chase as Spock and Dan Aykroyd as McCoy.[79] In the 1980s, Saturday Night Live did a sketch with William Shatner reprising his Captain Kirk role in The Restaurant Enterprise, preceded by a sketch in which he played himself at a Trek convention angrily telling fans to "Get a Life", a phrase that has become part of Trek folklore.[80] In Living Color continued the tradition in a sketch where Captain Kirk is played by a fellow Canadian Jim Carrey.[81]

A feature-length film that indirectly parodies Star Trek is Galaxy Quest. This film is based on the premise that aliens monitoring the broadcast of an Earth-based TV series called Galaxy Quest, modeled heavily on Star Trek, believe that what they are seeing is real.[82] Many Star Trek actors have been quoted saying that Galaxy Quest was a brilliant parody.[83][84]

Star Trek has been blended with Gilbert and Sullivan at least twice. The North Toronto Players presented a Star Trek adaptation of Gilbert & Sullivan titled H.M.S. Starship Pinafore: The Next Generation in 1991 and an adaptation by Jon Mullich of Gilbert & Sullivan's H.M.S. Pinafore that sets the operetta in the world of Star Trek has played in Los Angeles and was attended by series luminaries Nichelle Nichols,[citation needed] D.C. Fontana and David Gerrold.[85] A similar blend of Gilbert and Sullivan and Star Trek was presented as a benefit concert in San Francisco by the Lamplighters in 2009. The show was titled Star Drek: The Generation After That. It presented an original story with Gilbert and Sullivan melodies.[86]

Both The Simpsons and Futurama television series and others have had many individual episodes parodying Star Trek or with Trek allusions.[87] An entire series of films and novels from Finland titled Star Wreck also parodies Star Trek.[citation needed]

Star Trek has been parodied in several non-English movies, including the German Traumschiff Surprise - Periode 1 which features a gay version of The Original Series bridge crew and a Turkish film that spoofs that same series' episode "The Man Trap" in one of the series of films based on the character Turist Ömer.[citation needed]

Notable fan fiction

Although Star Trek has been off the air since 2005, CBS and Paramount pictures have allowed fan-produced shows to be created. While not officially part of the Star Trek universe, several veteran Star Trek actors, actresses, and writers have contributed their talents to these many of these productions. While none of these films have been created for profit, several fan productions have turned to crowdfunding from sites such as Kickstarter to help with production costs.[88]
Two series set during the TOS time period are Star Trek Continues and the Hugo award nominated Star Trek: Phase II. Another series, Star Trek Hidden Frontier, takes place on the Briar Patch, a region of space introduced in Star Trek Insurrection. It has had over 50 episodes produced, and has two spin-off series, Star Trek: Odyssey and Star Trek: The Helena Chronicles. Several standalone fan films have been created including Star Trek: Of Gods and Men. Future fan films include, Star Trek: Axanar and Star Trek: Renegades.[89] Audio only fan productions includes Star Trek: The Continuing Mission. Several fan film parodies have also been created.

Awards and honors

Of the various science fiction awards for drama, only the Hugo Award dates back as far as the original series.[Note 12] In 1968, all five nominees for a Hugo Award were individual episodes of Star Trek, as were three of the five nominees in 1967.[Note 13] The only Star Trek series to not get even a Hugo nomination are the animated series and Voyager, though only the original series and Next Generation ever won the award. No Star Trek featured film has ever won a Hugo, though a few were nominated. In 2008, the fan made episode of Star Trek: New Voyages entitled "World Enough and Time" was nominated for the Hugo for Best Short Drama.[90]

The two Star Trek series to win multiple Saturn awards during their run were The Next Generation (twice winning for best television series) and Voyager (twice winning for best actress – Kate Mulgrew and Jeri Ryan).[Note 14] The original series retroactively won a Saturn Award for best DVD release. Several Star Trek films have won Saturns including categories such as best actor, actress, director, costume design, and special effects. However, Star Trek has never won a Saturn for best make-up.[91]

As for non science fiction specific awards, the Star Trek series has won 31 Emmy Awards.[92] The eleventh Star Trek film won the 2009 Academy Award for Best Makeup, the franchise's first Academy Award.[93]

Corporate ownership

At Star Trek '​s creation, Norway Productions, Roddenberry's production company, shared ownership with Desilu Productions and, after Gulf+Western acquired Desilu in 1967, with Paramount Pictures, the conglomerate's film studio. Paramount did not want to own the unsuccessful show; net profit was to be shared between Norway, Desilu/Paramount, Shatner, and NBC but Star Trek lost money, and the studio did not expect to syndicate it. In 1970 Paramount offered to sell all rights to Star Trek to Roddenberry, but he could not afford the $150,000 ($911,000 today) price.[12]

In 1989, Gulf+Western renamed itself as Paramount Communications, and in 1994 merged with Viacom.[12] In 2005, Viacom divided into CBS Corporation, whose CBS Television Studios subsidiary retained the Star Trek brand, and Viacom, whose Paramount Pictures subsidiary retained the Star Trek film library and rights to make additional films, along with video distribution rights to the TV series on behalf of CBS.[94][12]

Texas To Become US Clean Energy Leader

February 16th, 2015 by
Original link:  http://cleantechnica.com/2015/02/16/texas-become-us-clean-energy-leader/

The US state of Texas already has a booming wind industry to its credit alongside its historic attachment to oil and natural gas, and a new initiative is set to bust the field wide open along with other clean energy sectors. Texas has just been tapped to be one of four founding states in the Energy Department’s new Clean Energy Incubator Network, which is aimed at getting cutting edge cleantech off the drawing board and into the marketplace as quickly as possible.

To give you a taste of what’s to come we’re going to look at a wind turbine company that’s already in the Texas hopper, but first let’s take a look at the forces behind the Clean Energy Incubator Network.
NREL Clean Energy Incubator Network

The Clean Energy Incubator Network

The Clean Energy Incubator Network (CEIN) is funded through the Energy Department’s National Renewable Energy Laboratory in partnership with the utility industry’s Electric Power Research Institute (EPRI).

We’ve covered the lab many times — it’s one of the pivotal forces in cutting edge solar technology, for example — but not so much EPRI. That’s our bad, since EPRI membership represents a huge chunk of the electricity generated in the US, and the organization has been all over clean energy.
Here’s just a sampling: back in 2010, EPRI launched a partnership with the Solar Technology Acceleration Center, in 2013 it got involved in a new ocean power initiative, and earlier this year it was recruited into a major solar resiliency initiative spearheaded by the City University of New York.
CEIN pulls these two clean energy powerhouses together with academic and research institutes to help energy entrepreneurs get their projects off the ground. Here’s the pitch from the CEIN blog:

If you are an energy entrepreneur, this network is designed to provide you with a collection of the top resources you need to launch your company or commercialize your technology, including information about leading incubators, funding opportunities, testing facilities, mentors, and more…
…Distributed generation, automation, sensors, micro grids, electric cars, and storage are just some of the areas experiencing dramatic change, and this will surely only accelerate as tipping points are reached across clean energy technologies.

The four founding states are Illinois (headed up by Clean Energy Trust), Michigan (NextEnergy), California (LA Cleantech Incubator, and Texas (Austin Technology Incubator).

The Austin Technology Incubator is headquartered at the University of Texas in Austin, and if you noodle around on their website you’ll find some cool cutting edge clean energy companies that have already come under the Incubator’s wing.

Leaping Over Clean Energy Hurdles

That’s where we found the aforementioned wind turbine company, Wetzel Engineering (aka Wetzel Blade).

The company caught our eye because it has come up with an ingenious  solution to a problem that has bedeviled the wind industry, which is how to get those massive turbine blades out of the blade factory and over to their new homes.

Transporting turbine blades and other large components is a huge issue for the wind industry because it often involves special permits, escorts, alternate routes, and even infrastructure adjustment. The costs pile up, along with the delays, eating into profitability and cost-effectiveness.

Wetzel’s solution sounds simple enough, though the devil is in the details: a modular turbine blade.
We saw the modular solution at play for wind turbine towers last year, the idea being to break the tower down into parts that could be transported along standard routes, with no special permits or adjustments required.

As reported by our friends over at Wind Power Engineering last fall, the Wetzel design consists of seven modular pieces that can be transported for less than a standard blade.

The pieces are designed to be assembled on site without specialized requirements, further keeping costs under control. The firm expects that the seven-piece blade will also cost less to manufacture, and it anticipates improvements in quality over conventional blades, too.

This is the kind of manufacturing and transportation breakthrough that is required if the wind industry is to continue scaling up into taller towers and longer blades, so we’ll keep an eye on that.

We’ll also be keeping a close eye on the CEIN website (here’s that link again). There’s not a whole lot to it right now, but plans are in the works to include funding opportunities, resources for laboratories and events, and an “evaluation toolkit” that will tailor resources to start-ups based on how ready they are for commercialization.

As for EPRI, the organization will work in concert with the website to stage in-person and web-based events geared toward sharing best practices.

The first event was held just last week at the ARPA-E Energy Innovation Summit, so stay tuned for lots more on new developments in Texas and elsewhere.

Cladistics



From Wikipedia, the free encyclopedia

Cladistics (from Greek κλάδος, klados, i.e. "branch")[1] is an approach to biological classification in which organisms are grouped together based on whether or not they have one or more shared unique characteristics that come from the group's last common ancestor and are not present in more distant ancestors. Therefore, members of the same group are thought to share a common history and are considered to be more closely related.[2][3][4][5]

The original methods used in cladistic analysis and the school of taxonomy derived from it originated in the work of the German entomologist Willi Hennig, who referred to it as phylogenetic systematics (also the title of his 1966 book); the terms "cladistics" and "clade" were popularized by other researchers. Cladistics in the original sense refers to a particular set of methods used in phylogenetic analysis, although it is now sometimes used to refer to the whole field.[6]

The techniques of cladistics, and sometimes the terminology, have been successfully applied to other disciplines: for example, to determine the relationships between the surviving manuscripts of the Canterbury Tales,[7] or also between 53 manuscripts of the Sanskrit Charaka Samhita.[8]

History

What is now called the cladistic method appeared as early as 1901 with a work by Peter Chalmers Mitchell (for birds)[9][10] and subsequently by Robert John Tillyard (for insects) in 1921,[10] and W. Zimmermann (for plants) in 1943.[11] The term "clade" was introduced in 1958 by Julian Huxley after having been coined by Lucien Cuénot in 1940,[12] "cladogenesis" in 1958,[13] "cladistic" by Cain and Harrison in 1960,[14] "cladist" (for an adherent of Hennig's school) by Mayr in 1965,[15] and "cladistics" in 1966.[13] Hennig referred to his own approach as "phylogenetic systematics". From the time of his original formulation until the end of the 1970s, cladistics competed as an analytical and philosophical approach to phylogenetic inference with phenetics and so-called evolutionary taxonomy. Phenetics was championed at this time by the numerical taxonomists Peter Sneath and Robert Sokal and the evolutionary taxonomist Ernst Mayr.

Originally conceived, if only in essence, by Willi Hennig in a book published in 1950, cladistics did not flourish until its translation into English in 1966 (Lewin 1997). Today, cladistics is the most popular method for constructing phylogenies not only from morphological data but also from molecular. Unlike phenetics, cladistics is specifically aimed at reconstructing evolutionary histories.

In the 1990s, the development of effective polymerase chain reaction techniques allowed the application of cladistic methods to biochemical and molecular genetic traits of organisms, as well as to anatomical ones, vastly expanding the amount of data available for phylogenetics. At the same time, cladistics rapidly became the dominant set of methods of phylogenetics in evolutionary biology, because computers made it possible to process large quantities of data about organisms and their characteristics.

The way for computational phylogenetics was paved by phenetics,[16] a set of methods commonly used from the 1950s to 1980s and to some degree later. Phenetics did not try to reconstruct phylogenetic trees; rather, it tried to build dendrograms from similarity data; its algorithms required less computer power than phylogenetic ones.

Methodology

The cladistic method interprets each character state transformation implied by the distribution of shared character states among taxa (or other terminals) as a potential piece of evidence for grouping. 
 
The outcome of a cladistic analysis is a cladogram – a tree-shaped diagram (dendrogram)[17] that is interpreted to represent the best hypothesis of phylogenetic relationships. Although traditionally such cladograms were generated largely on the basis of morphological characters and originally calculated by hand, genetic sequencing data and computational phylogenetics are now commonly used in phylogenetic analyses, and the parsimony criterion has been abandoned by many phylogeneticists in favor of more "sophisticated" but less parsimonious evolutionary models of character state transformation. Cladists contend that these models are unjustified.[clarification needed]
Every cladogram is based on a particular dataset analyzed with a particular method. Datasets are tables consisting of molecular, morphological, ethological[18] and/or other characters and a list of operational taxonomic units (OTUs) which may be genes, individuals, populations, species, or larger taxa that are presumed to be monophyletic and therefore to form, all together, one large clade; phylogenetic analysis infers the branching pattern within that clade. Different datasets and different methods, not to mention violations of the mentioned assumptions, often result in different cladograms. Only scientific investigation can show which is more likely to be correct.

Until recently, for example, cladograms like the following have generally been accepted as accurate representations of the ancestral relations among turtles, lizards, crocodilians, and birds:[19]

  
Testudines   turtles

Diapsida   
Lepidosauria   lizards

Archosauria
Crocodylomorpha   crocodilians

Dinosauria birds




If this phylogenetic hypothesis is correct, then the last common ancestor of turtles and birds, at the ⊣ connection near the (a ⊤ in some browsers) lived earlier than the last common ancestor of lizards and birds, near the . Most molecular evidence, however, produces cladograms more like this:[20]

Diapsida   
Lepidosauria   lizards

Lepidosauria
Testudines   turtles

Archosauria  
Crocodylomorpha   crocodilians

Dinosauria birds





If this is accurate, then the last common ancestor of turtles and birds lived later than the last common ancestor of lizards and birds. Since the cladograms provide competing accounts of real events, at most one of them is correct.

Cladogram of the primates, showing a monophyletic taxon (a clade: the simians or Anthropoidea, in yellow), a paraphyletic taxon (the prosimians, in blue, including the red patch), and a polyphyletic taxon (the nocturnal primates – the lorises and the tarsiers – in red)

The cladogram to the right represents the current universally accepted hypothesis that all primates, including strepsirrhines like the lemurs and lorises, had a common ancestor all of whose descendants were primates, and so form a clade; the name Primates is therefore recognized for this clade. Within the primates, all anthropoids (monkeys, apes and humans) are hypothesized to have had a common ancestor all of whose descendants were anthropoids, so they form the clade called Anthropoidea. The "prosimians", on the other hand, form a paraphyletic taxon. The name Prosimii is not used in phylogenetic nomenclature, which names only clades; the "prosimians" are instead divided between the clades Strepsirhini and Haplorhini, where the latter contains Tarsiiformes and Anthropoidea.

Terminology for character states

The following terms, coined by Hennig, are used to identify shared or distinct character states among groups:[21][22][23]
  • A plesiomorphy ("close form") or ancestral state is a character state that a taxon has retained from its ancestors. When two or more taxa that are not nested within each other share a plesiomorphy, it is a symplesiomorphy (from syn-, "together"). Symplesiomorphies do not mean that the taxa that exhibit that character state are necessarily closely related. For example, Reptilia is traditionally characterized by (among other things) being cold-blooded (i.e. not maintaining a constant high body temperature), whereas birds are warm-blooded. Since cold-bloodedness is a plesiomorphy, inherited from the common ancestor of traditional reptiles and birds, and thus a symplesiomorphy of turtles, snakes and crocodiles (among others), it does not mean that turtles, snakes and crocodiles form a clade that excludes the birds.
  • An apomorphy ("separate form") or derived state is an innovation. It can thus be used to diagnose a clade – or even to help define a clade name in phylogenetic nomenclature. Features that are derived in individual taxa (a single species or a group that is represented by a single terminal in a given phylogenetic analysis) are called autapomorphies (from auto-, "self"). Autapomorphies express nothing about relationships among groups; clades are identified (or defined) by synapomorphies (from syn-, "together"). For example, the possession of digits that are homologous with those of Homo sapiens is a synapomorphy within the vertebrates. The tetrapods can be singled out as consisting of the first vertebrate with such digits homologous to those of Homo sapiens together with all descendants of this vertebrate (an apomorphy-based phylogenetic definition).[24] Importantly, snakes and other tetrapods that do not have digits are nonetheless tetrapods: other characters, such as amniotic eggs and diapsid skulls, indicate that they descended from ancestors that possessed digits which are homologous with ours.
  • A character state is homoplastic or "an instance of homoplasy" if it is shared by two or more organisms but is absent from their common ancestor or from a later ancestor in the lineage leading to one of the organisms. It is therefore inferred to have evolved by convergence or reversal. Both mammals and birds are able to maintain a high constant body temperature (i.e. they are warm-blooded). However, the accepted cladogram explaining their significant features indicates that their common ancestor is in a group lacking this character state, so the state must have evolved independently. Warm-bloodedness is separately a synapomorphy of mammals (or a larger clade) and of birds (or a larger clade), but it is not a synapomorphy of any group including both these clades. Hennig's Auxiliary Principle [25] states that shared character states should be considered evidence of grouping unless they are contradicted by the weight of other evidence; thus, homoplasy of some feature among members of a group may only be inferred after a phylogenetic hypothesis for that group has been established.
The terms plesiomorphy and apomorphy are relative; their application depends on the position of a group within a tree. For example, when trying to decide whether the tetrapods form a clade, an important question is whether having four limbs is a synapomorphy of the earliest taxa to be included within Tetrapoda: did all the earliest members of the Tetrapoda inherit four limbs from a common ancestor, whereas all other vertebrates did not, or at least not homologously? By contrast, for a group within the tetrapods, such as birds, having four limbs is a plesiomorphy. Using these two terms allows a greater precision in the discussion of homology, in particular allowing clear expression of the hierarchical relationships among different homologous features.

It can be difficult to decide whether a character state is in fact the same and thus can be classified as a synapomorphy which may identify a monophyletic group or whether it only appears to be the same and is thus a homoplasy which cannot identify such a group. There is a danger of circular reasoning: assumptions about the shape of a phylogenetic tree are used to justify decisions about character states, which are then used as evidence for the shape of the tree.[26] Phylogenetics uses various forms of parsimony to decide such questions; the conclusions reached often depend on the dataset and the methods. Such is the nature of empirical science, and for this reason, most cladists refer to their cladograms as hypotheses of relationship. Cladograms that are supported by a large number and variety of different kinds of characters are viewed as more robust than those based on more limited evidence.

Terminology for taxa

Mono-, para- and polyphyletic taxa can be understood based on the shape of the tree (as done above), as well as based on their character states.[22][23][27] These are compared in the table below.

Term Node-based definition Character-based definition
Monophyly A clade, a monophyletic taxon, is a taxon which includes all descendants of an inferred ancestor. A clade is characterized by one or more apomorphies: derived character states present in the first member of the taxon, inherited by its descendants (unless secondarily lost), and not inherited by any other taxa.
Paraphyly A paraphyletic assemblage is one which is constructed by taking a clade and removing one or more smaller clades.[28] (Removing one clade produces a singly paraphyletic assemblage, removing two a doubly paraphylectic assemblage, and so on.)[29] A paraphyletic assemblage is characterized by one or more plesiomorphies: character states inherited from ancestors but not present in all of their descendants. As a consequence, a paraphyletic assemblage is truncated, in that it excludes one or more clades from an otherwise monophyletic taxon. An alternative name is evolutionary grade, referring to an ancestral character state within the group. While paraphyletic assemblages are popular among paleontologists and evolutionary taxonomists, cladists do not recognize paraphyletic assemblages as having any formal information content – they are merely parts of clades.
Polyphyly A polyphyletic assemblage is one which is neither monophyletic nor paraphyletic. A polyphyletic assemblage is characterized by one or more homoplasies: character states which have converged or reverted so as to be the same but which have not been inherited from a common ancestor. No systematist recognizes polyphyletic assemblages as taxonomically meaningful entities, although ecologists sometimes consider them meaningful labels for functional participants in ecological communities (e. g., primary producers, detritivores, etc.).

Criticism

Cladistics, either generally or in specific applications, has been criticized from its beginnings. Decisions as to whether particular character states are homologous, a precondition of their being synapomorphies, have been challenged as involving circular reasoning and subjective judgements.[30] Transformed cladistics arose in the late 1970s in an attempt to resolve some of these problems by removing phylogeny from cladistic analysis, however it has remained unpopular.

However, homology is usually determined from analysis of the results which are evaluated with homology measures, mainly the CI (consistency index) and RI (retention index), which, it has been claimed,[by whom?] makes the process objective. Also, homology can be equated to synapomorphy, which is what Patterson has done.[31]

In disciplines other than biology

The comparisons used to acquire data on which cladograms can be based are not limited to the field of biology.[32] Any group of individuals or classes that are hypothesized to have a common ancestor, and to which a set of common characteristics may or may not apply, can be compared pairwise.
Cladograms can be used to depict the hypothetical descent relationships within groups of items in many different academic realms. The only requirement is that the items have characteristics that can be identified and measured. Cladistic methods outside of biology address the reconstruction of lineages in a variety of ways.

Anthropology and archaeology:[33] Cladistic methods have been used to reconstruct the development of cultures or artifacts using groups of cultural traits or artifact features.

Comparative mythology and folktale use cladistic methods to reconstruct the protoversion of many myths. Mythological phylogenies constructed with mythemes clearly support low horizontal transmissions (borrowings), historical (sometimes Palaeolithic) diffusions and punctuated evolution.[34] They also are a powerful way to test hypotheses about cross-cultural relationships among folktales.[35][36]

Historical linguistics:[37] Cladistic methods have been used to reconstruct the phylogeny of languages using linguistic features. This is similar to the traditional comparative method of historical linguistics, but is more explicit in its use of parsimony and allows much faster analysis of large datasets (computational phylogenetics).

Textual criticism or stemmatics:[8][38] Cladistic methods have been used to reconstruct the phylogeny of manuscripts of the same work (and reconstruct the lost original) using distinctive copying errors as apomorphies. This differs from traditional historical-comparative linguistics in enabling the editor to evaluate and place in genetic relationship large groups of manuscripts with large numbers of variants that would be impossible to handle manually. It also enables parsimony analysis of contaminated traditions of transmission that would be impossible to evaluate manually in a reasonable period of time.
