WikiProject Novels
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

Ace Books
Ace Books is a publisher of science fiction (SF) and fantasy books founded in New York City in 1952 by Aaron A. Wyn. It began as a genre publisher of mysteries and westerns, and soon branched out into other genres, publishing its first science fiction title in 1953. This was successful, and science fiction titles outnumbered both mysteries and westerns within a few years. Other genres also made an appearance, including nonfiction, gothic novels, media tie-in novelizations, and romances. Ace became known for the ''tête-bêche'' binding format used for many of its early books, although it did not originate the format. Most of the early titles were published in this "Ace Double" format, and Ace continued to issue books in varied genres, bound ''tête-bêche'', until 1973. Ace, along with Ballantine Books, was one of the leading science fiction publishers for its first ten years of operation. The death of owner A. A. Wyn in 1967 set the stage for a later decline in the publishe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Edgar Rice Burroughs
Edgar Rice Burroughs (September 1, 1875 – March 19, 1950) was an American author, best known for his prolific output in the adventure, science fiction, and fantasy genres. Best-known for creating the characters Tarzan and John Carter, he also wrote the ''Pellucidar'' series, the ''Amtor'' series, and the '' Caspak'' trilogy. Tarzan was immediately popular, and Burroughs capitalized on it in every way possible, including a syndicated Tarzan comic strip, movies, and merchandise. Tarzan remains one of the most successful fictional characters to this day and is a cultural icon. Burroughs's California ranch is now the center of the Tarzana neighborhood in Los Angeles, named after the character. Burroughs was an explicit supporter of eugenics and scientific racism in both his fiction and nonfiction; Tarzan was meant to reflect these concepts. Biography Early life and family Burroughs was born on September 1, 1875, in Chicago (he later lived for many years in the suburb of ...

Barsoom
Barsoom is a fictional representation of the planet Mars created by American pulp fiction author Edgar Rice Burroughs. The first Barsoom tale was serialized as ''Under the Moons of Mars'' in 1912 and published as a novel as ''A Princess of Mars'' in 1917. Ten sequels followed over the next three decades, further extending his vision of Barsoom and adding other characters. The ''Barsoom'' series, where John Carter in the late 19th century is mysteriously transported from Earth to a Mars suffering from dwindling resources, has been cited by many well known science fiction writers as having inspired them. Elements of the books have been adapted by many writers in novels, short stories, comics, television, and film.

Sword And Planet
Sword and planet is a subgenre of science fantasy that features rousing adventure stories set on other planets, and usually featuring humans as protagonists. The name derives from the heroes of the genre engaging their adversaries in hand-to-hand combat primarily with simple melée weapons such as swords, even in a setting that often has advanced technology. Although there are works that herald the genre, such as Percy Greg's ''Across the Zodiac'' (1880) and Edwin Lester Arnold's '' Lieut. Gullivar Jones: His Vacation'' (1905; published in the US in 1964 as ''Gulliver of Mars''), the prototype for the genre is ''A Princess of Mars'' by Edgar Rice Burroughs originally serialized by ''All-Story'' in 1912 as "Under the Moons of Mars". The genre predates the mainstream popularity of science fiction proper, and does not necessarily feature any scientific rigor, being instead romantic tales of high adventure. For example, little thought is given to explaining why the environment of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Perpetual Motion
Perpetual motion is the motion of bodies that continues forever in an unperturbed system. A perpetual motion machine is a hypothetical machine that can do work infinitely without an external energy source. This kind of machine is impossible, as it would violate either the first law of thermodynamics, first or second law of thermodynamics or both. These laws of thermodynamics apply regardless of the size of the system. For example, the motions and rotations of celestial bodies such as planets may appear perpetual, but are actually subject to many processes that slowly dissipate their kinetic energy, such as solar wind, interstellar medium resistance, gravitational radiation and thermal radiation, so they will not keep moving forever. Thus, machines that extract energy from finite sources will not operate indefinitely, because they are driven by the energy stored in the source, which will eventually be exhausted. A common example is devices powered by ocean currents, whose energ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
