Pierson's Puppeteers, often known just as Puppeteers, are a fictional alien race from American author Larry Niven's ''Known Space'' books. The race first appeared in Niven’s novella ''Neutron Star (short story), Neutron Star''. Biology and sociology The sobriquet "Pierson's" comes from the name of the human who made First contact (science fiction), first contact in the early 26th century in the ''Known Space'' timeline. According to the Niven story ''The Soft Weapon'', Pierson was a crewman aboard a spaceship at a time when there was a Camp (style), camp revival of the ancient ''Time for Beany'' TV show featuring Beany and Cecil#Cecil, Cecil the Seasick Sea Serpent, an animated character based on a hand puppet; Pierson accordingly described the alien he had met as a Puppeteer, given some resemblance of the head and neck with Cecil. Puppeteers dealing with humans usually give themselves the names of centaurs and other figures in Greek mythology, such as Nessus (mythology), Nessu ...

Herbivore
A herbivore is an animal anatomically and physiologically adapted to eating plant material, for example foliage or marine algae, for the main component of its diet. As a result of their plant diet, herbivorous animals typically have mouthparts adapted to rasping or grinding. Horses and other herbivores have wide flat teeth that are adapted to grinding grass, tree bark, and other tough plant material. A large percentage of herbivores have mutualistic gut flora that help them digest plant matter, which is more difficult to digest than animal prey. This flora is made up of cellulose-digesting protozoans or bacteria. Etymology Herbivore is the anglicized form of a modern Latin coinage, ''herbivora'', cited in Charles Lyell's 1830 ''Principles of Geology''.J.A. Simpson and E.S.C. Weiner, eds. (2000) ''The Oxford English Dictionary'', vol. 8, p. 155. Richard Owen employed the anglicized term in an 1854 work on fossil teeth and skeletons. ''Herbivora'' is derived from Latin ''herba' ...

Klemperer Rosette
A Klemperer rosette is a gravitational system of heavier and lighter bodies orbiting in a regular repeating pattern around a common barycenter. It was first described by W. B. Klemperer in 1962, and is a special case of a central configuration. Klemperer described the system as follows: The simplest rosette would be a series of four alternating heavier and lighter bodies, 90 degrees from one another, in a rhombic configuration eavy, Light, Heavy, Light where the two larger bodies have the same mass, and likewise the two smaller bodies have the same mass. The number of "mass types" can be increased, so long as the arrangement pattern is cyclic: e.g. 1,2,3 ... 1,2,3 1,2,3,4,5 ... 1,2,3,4,5 1,2,3,3,2,1 ... 1,2,3,3,2,1 etc. Klemperer also mentioned octagonal and rhombic rosettes. While all Klemperer rosettes are vulnerable to destabilization, the hexagonal rosette has extra stability because the "planets" sit in each other's L4 and L5 Lagrangian points. Misuse and missp ...

Known Space
Known Space is the fictional setting of about a dozen science fiction novels and several collections of short stories written by Larry Niven. It has also become a shared universe in the spin-off ''Man-Kzin Wars'' anthologies. The Internet Speculative Fiction Database (ISFDB) catalogs all works set in the fictional universe that includes Known Space under the series name Tales of Known Space, which was the title of a 1975 collection of Niven's short stories. The first-published work in the series, which was Niven's first published piece was "The Coldest Place", in the December 1964 issue of '' If'' magazine, edited by Frederik Pohl. This was the first-published work in the 1975 collection. The stories span approximately one thousand years of future history, from the first human explorations of the Solar System to the colonization of dozens of nearby systems. Late in the series, Known Space is an irregularly shaped "bubble" about 60 light-years across. The epithet "Known Space" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Teleportation
Teleportation is the hypothetical transfer of matter or energy from one point to another without traversing the physical space between them. It is a common subject in science fiction literature and in other popular culture. Teleportation is often paired with time travel, being that the travelling between the two points takes an unknown period of time, sometimes being immediate. An apport is a similar phenomenon featured in parapsychology and spiritualism. There is no known physical mechanism that would allow for teleportation. Frequently appearing scientific papers and media articles with the term ''teleportation'' typically report on so-called " quantum teleportation", a scheme for information transfer which, due to the no-communication theorem, still would not allow for faster-than-light communication. Etymology The use of the term ''teleport'' to describe the hypothetical movement of material objects between one place and another without physically traversing the distance ...

Ringworld
''Ringworld'' is a 1970 science fiction novel by Larry Niven, set in his Known Space universe and considered a classic of science fiction literature. ''Ringworld'' tells the story of Louis Wu and his companions on a mission to the Ringworld, a rotating wheel artificial world, an alien construct in space in diameter. Niven later added three sequel novels and then cowrote, with Edward M. Lerner, four prequels and a final sequel; the five latter novels constitute the Fleet of Worlds series. All the novels in the Ringworld series tie into numerous other books set in Known Space. ''Ringworld'' won the Nebula Award in 1970, as well as both the Hugo Award and Locus Award in 1971. Plot summary On planet Earth in 2850 AD, Louis Gridley Wu is celebrating his 200th birthday. Despite his age, Louis is in perfect physical condition due to the longevity drug boosterspice. He meets Nessus, a Pierson's puppeteer, who offers him a mysterious job. Intrigued, Louis eventually accepts. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nessus (Pierson's Puppeteer)
This is a list of fictional characters featured in the ''Known Space'' novels by Larry Niven. Individual characters Sigmund Ausfaller Sigmund Ausfaller, a native of Earth, is a member of the Amalgamated Regional Militia ("ARM"), working in the Bureau of Alien Affairs on Earth. To protect puppeteer (and Earth) interests, in "Neutron Star" Ausfaller plants a bomb in the lifesystem of Shaeffer's ship, the ''Skydiver'', so that Shaeffer will not attempt to steal it. Years later, in ''The Borderlands of Sol'', when Shaeffer encounters him on Jinx, he offers Shaeffer and Carlos Wu a ride home to Earth on his ship, ''Hobo Kelly'', in hopes of attracting the attention of whoever or whatever was causing ships to disappear when entering or leaving Sol system. Some years later, Ausfaller, having almost caught up with Shaeffer on Fafnir, is killed by Ander Smittarasheed in order to protect Smittarasheed's interest in the special nanotechnology autodoc developed by Carlos Wu, left on Fafnir wh ...

Spermatozoon
A spermatozoon (; also spelled spermatozoön; ; ) is a motile sperm cell, or moving form of the haploid cell that is the male gamete. A spermatozoon joins an ovum to form a zygote. (A zygote is a single cell, with a complete set of chromosomes, that normally develops into an embryo.) Sperm cells contribute approximately half of the nuclear genetic information to the diploid offspring (excluding, in most cases, mitochondrial DNA). In mammals, the sex of the offspring is determined by the sperm cell: a spermatozoon bearing an X chromosome will lead to a female (XX) offspring, while one bearing a Y chromosome will lead to a male (XY) offspring. Sperm cells were first observed in Antonie van Leeuwenhoek's laboratory in 1677. Mammalian spermatozoon structure, function, and size Humans The human sperm cell is the reproductive cell in males and will only survive in warm environments; once it leaves the male body the sperm's survival likelihood is reduced and it may die, thereby dec ...

Ovum
The egg cell, or ovum (plural ova), is the female reproductive cell, or gamete, in most anisogamous organisms (organisms that reproduce sexually with a larger, female gamete and a smaller, male one). The term is used when the female gamete is not capable of movement (non-motile). If the male gamete (sperm) is capable of movement, the type of sexual reproduction is also classified as oogamous. A nonmotile female gamete formed in the oogonium of some algae, fungi, oomycetes, or bryophytes is an oosphere. When fertilized the oosphere becomes the oospore. When egg and sperm fuse during fertilisation, a diploid cell (the zygote) is formed, which rapidly grows into a new organism. History While the non-mammalian animal egg was obvious, the doctrine ''ex ovo omne vivum'' ("every living nimal comes froman egg"), associated with William Harvey (1578–1657), was a rejection of spontaneous generation and preformationism as well as a bold assumption that mammals also reproduced via ...

Parasite
Parasitism is a close relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. The entomologist E. O. Wilson has characterised parasites as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as Armillaria mellea, honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the Orobanchaceae, broomrapes. There are six major parasitic Behavioral ecology#Evolutionarily stable strategy, strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism (by contact), wikt:trophic, trophicallytransmitted parasitism (by being eaten), Disease vector, vector-transmitted parasitism, parasitoidism, and micropreda ...
