  • "In celestial mechanics, the mean anomaly is a parameter relating position and time for a body moving in a Kepler orbit. It is based on the fact that equal areas are swept at the focus in equal intervals of time."

    "The mean anomaly is one of three angular parameters ('anomalies') that define a position along an orbit; the other two being the eccentric anomaly and the true anomaly."

  • Autothysis is the process where an animal destroys itself via an internal rupturing or explosion of an organ which ruptures the skin. The term was proposed by Maschwitz and Maschwitz in 1974 to describe the defensive mechanism of the carpenter ant (Camponotus saundersi). It is caused by a contraction of muscles around a large gland that leads to the gland wall breaking. Some termites (such as the soldiers of Globitermes sulphureus) release a sticky secretion by rupturing a gland near the skin of their neck, producing a tar baby effect in defense against ants. It is a form of suicidal altruism. (Wikipedia)

  • "Clever Hans (in German, der Kluge Hans) was an Orlov Trotter horse that was claimed to have been able to perform arithmetic and other intellectual tasks.

    After a formal investigation in 1907, psychologist Oskar Pfungst demonstrated that the horse was not actually performing these mental tasks, but was watching the reaction of his human observers. Pfungst discovered this artifact in the research methodology, wherein the horse was responding directly to involuntary cues in the body language of the human trainer, who had the faculties to solve each problem. The trainer was entirely unaware that he was providing such cues. In honour of Pfungst's study, the anomalous artifact has since been referred to as the Clever Hans effect and has continued to be important knowledge in the observer-expectancy effect and later studies in animal cognition."

  • In computability theory, a machine that always halts—also called a decider (Sipser, 1996) or a total Turing machine (Kozen, 1997)—is a Turing machine that halts for every input.

    Because it always halts, the machine is able to decide whether a given string is a member of a formal language. The class of languages which can be decided by such machines is exactly the set of recursive languages. However, due to the Halting Problem, determining whether an arbitrary Turing machine halts on an arbitrary input is itself an undecidable decision problem.

  • The sexy son hypothesis of evolutionary biology was first proposed by Fisher in 1930. 'The sexy son hypothesis' proposes that a female animal's optimal choice among potential mates is a male whose genes will produce male offspring with the best chance of reproductive success. In particular, the sexy son hypothesis implies that a potential mate's capacity as a caregiver or any other direct benefits the male can offer the female (e.g., nuptial gifts, good territory) are irrelevant to his value as the potential father of the female's offspring. What matters are her sexy sons' future breeding successes (like that of their promiscuous father) in creating large numbers of offspring carrying copies of the female's genes.

  • The gastric-brooding frogs or Platypus frogs (Rheobatrachus) were a genus of ground-dwelling frogs native to Queensland in eastern Australia. The genus consisted of only two species, both of which became extinct in the mid-1980s. The genus was unique because it contained the only two known frog species that incubated the prejuvenile stages of their offspring in the stomach of the mother. (Wikipedia)

    February 7, 2012

  • Mouthbrooding, also known as oral incubation and buccal incubation, is the care given by some groups of animals to their offspring by holding them in the mouth of the parent for extended periods of time. Although mouthbrooding is performed by a variety of different animals, most notably Darwin's frog, fishes are by far the most diverse mouthbrooders. (Wikipedia)

  • From Wikipedia:

    In the mathematics of social science, and especially game theory, a moving-knife procedure is a type of solution to the fair division problem. The canonical example is the division of a cake using a knife.

    The simplest example is a moving-knife equivalent of the I cut, you choose scheme, sometimes known as Austin's moving-knife procedure. One player moves the knife across the cake, conventionally from left to right. The cake is cut when either player calls "stop". If each player calls stop when he or she perceives the knife to be at the 50-50 point, then the first player to call stop will produce an envy-free division if the caller gets the left piece and the other player gets the right piece. Note that this procedure is not necessarily efficient.

    Generalizing this scheme to more than two players cannot be done by a discrete procedure without sacrificing envy-freeness.

    February 4, 2012

  • From Wikipedia:

    The hand of benediction results from a severed median nerve at the level of the elbow or upper arm. The ability to flex the digits 2–3 at the metacarpophalangeal joints, proximal interphalangeal joints and distal interphalangeal joints is lost. This is due to the loss of innervation of the lateral 2 lumbricals of the hand which are supplied by the median nerve. Flexion at the proximal interphalangeal joints of digits 4–5 is weakened, but flexion at the metocarpophalangeal joints and distal interphalangeal joints remains intact. The extensors are left unopposed and digits 2–3 remain extended while attempting to make a fist.

    The name arises from the invocation of a blessing used in Christian circles (see benediction).

  • See probability current.

    January 31, 2012

  • In quantum mechanics, the probability current (sometimes called probability flux) is a mathematical quantity describing the flow of probability density. Intuitively; if one pictures the probability density as an inhomogeneous fluid, then the probability current is the rate of flow of this fluid (change in probability per unit time). This is analogous to hydrodynamic mass currents and electromagnetic charge currents. (Wikipedia)

  • Sisyphus cooling is a mechanism through which atoms can be cooled using laser beams below the temperatures expected to be achieved by Doppler cooling. It comes about as a result of a polarization gradient created by two counter-propagating laser beams with orthogonal polarization. Atoms moving through the potential landscape created by the standing wave (created by the interference of the two counter-propagating beams) lose kinetic energy as they move to a potential maximum, at which point optical pumping moves them to a lower-energy state, thus losing the potential energy they had.

    January 24, 2012

  • A hydrostatic skeleton or hydroskeleton is a structure found in many cold-blooded organisms and soft-bodied animals consisting of a fluid-filled cavity, the coelom, surrounded by muscles. The pressure of the fluid and action of the surrounding circular and longitudinal muscles are used to change an organism's shape and produce movement, such as burrowing or swimming. (Wikipedia)

  • The End of Greatness is an observational scale discovered at roughly 100 Mpc (roughly 300 million lightyears) where the lumpiness seen in the large-scale structure of the universe is homogenized and isotropized as per the Cosmological Principle. The superclusters and filaments seen in smaller surveys are randomized to the extent that the smooth distribution of the universe is visually apparent. It was not until the redshift surveys of the 1990s were completed that this scale could accurately be observed. (Wikipedia)

  • A chilled margin is a shallow intrusive or volcanic rock texture characterised by a glassy or fine grained zone along the margin where the magma or lava has contacted air, water, or particularly much cooler rock. This is caused by rapid crystallization of the melt near the contact with the surrounding low temperature environment. In an intrusive case, the crystallized chilled margin may decrease in size or disappear by later remelting during magma flow, depending on magma heat flux. (Wikipedia)

  • The unmoved mover (οὐ κινούμενον κινεῖ) is a philosophical concept described by Aristotle as a primary cause or "mover" of all the motion in the universe. As is implicit in the name, the "unmoved mover" is not moved by any prior action. In Book 12 (Greek "Λ") of his Metaphysics, Aristotle describes the unmoved mover as being perfectly beautiful, indivisible, and contemplating only the perfect contemplation: itself contemplating.

  • In particle physics, a superpartner (also sparticle) is hypothetical elementary particle. Supersymmetry is one of the synergistic theories in current high-energy physics which predicts the existence of these "shadow" particles.

    The word superpartner is a portmanteau of the words supersymmetry and partner (sparticle is a portmanteau of supersymmetry and particle).

  • In a quantum field theory, charge screening can restrict the value of the observable "renormalized" charge of a classical theory. If the only allowed value of the renormalized charge is zero, the theory is said to be "trivial" or noninteracting. Thus, surprisingly, a classical theory that appears to describe interacting particles can, when realized as a quantum field theory, become a "trivial" theory of noninteracting free particles. This phenomenon is referred to as quantum triviality. (Wikipedia)

  • In physics, mirror matter, also called shadow matter or Alice matter, is a hypothetical counterpart to ordinary matter. Modern physics deals with three basic types of spatial symmetry: reflection, rotation and translation. The known elementary particles respect rotation and translation symmetry but do not respect mirror reflection symmetry (also called P-symmetry or parity). Of the four fundamental interactions—electromagnetism, the strong interaction, the weak interaction, and gravity—only the weak interaction breaks parity. (Wikipedia)

  • Micro black holes are tiny black holes, also called quantum mechanical black holes or mini black holes, for which quantum mechanical effects play an important role.

    It is possible that such quantum primordial black holes were created in the high-density environment of the early Universe (or big bang), or possibly through subsequent phase transitions. They might be observed by astrophysicists in the near future, through the particles they are expected to emit by Hawking radiation.

  • In ecology, a supertramp species is any type of animal which follows the "supertramp" strategy of high dispersion among many different habitats, towards none of which it is particularly specialized. Supertramp species are typically the first to arrive in newly available habitats, such as volcanic islands and freshly deforested land; they can have profoundly negative effects on more highly specialized flora and fauna, both directly through predation and indirectly through competition for resources.

    The name was coined by Jared Diamond in 1974, as an allusion to both the itinerant lifestyle of the tramp, and the then-popular band Supertramp.

  • In condensed matter physics, the term geometrical frustration (or in short: frustration) means a phenomenon in which the geometrical properties of the crystal lattice or the presence of conflicting atomic forces forbid simultaneous minimization of the interaction energies acting at a given site. This may lead to highly degenerate ground states with a nonzero entropy at zero temperature. Or in simple terms, the substance can never be completely frozen, because the structure it forms does not have a single minimal-energy state, so motion on a molecular scale continues even at absolute zero and even without input of energy.

  • Nonclassical light is light that cannot be described using classical electromagnetism; its characteristics are described by the quantised electromagnetic field and quantum mechanics. Nonclassical light has nonclassical noise properties called quantum noise, which can be understood on the basis of quantum optics.

    Common described forms of nonclassical light are the following:

    Squeezed light exhibits reduced noise in one quadrature component. The most familiar kinds of squeezed light have either reduced amplitude noise or reduced phase noise, with increased noise of the other kind.

    Fock states (also called photon number states) have a well defined number of photons (stored e.g. in a cavity), while the phase is totally undefined.

  • Lapsarianism is the set of Calvinist doctrines describing the theoretical order of God's decree (in his mind, before Creation), in particular concerning the order of his decree for the fall of man and reprobation. The name of the doctrine comes from the Latin lapsus meaning fall.

    Supralapsarianism (also antelapsarianism) is the view that God's decrees of election and reprobation logically preceded the decree of the fall while infralapsarianism (also called postlapsarianism and sublapsarianism) asserts that God's decrees of election and reprobation logically succeeded the decree of the fall. The words can also be used in connection with other topics, e.g. supra- and infralapsarian christology.

  • There are three very basic types of tears: basal tears, reflex tears and crying or weeping (psychic tears).

    The third category, in general, referred to as crying or weeping, is increased lacrimation due to strong emotional stress, anger, suffering, mourning, or physical pain. It does not occur during the brain's Fight-or-flight response because the sympathetic nervous system inhibits lacrimation. This practice is not restricted to negative emotions; many people cry when extremely happy. In humans, emotional tears can be accompanied by reddening of the face and sobbing — cough-like, convulsive breathing, sometimes involving spasms of the whole upper body. Tears brought about by emotions have a different chemical make-up than those for lubrication. (Wikipedia)

  • The acardiac twin is a parasitic twin that fails to develop a head, arms and a heart. The parasitic twin, little more than a torso with or without legs, receives its blood supply from the host twin by means of an umbilical cord-like structure, much like a fetus in fetu, except the acardiac twin is outside the host twin's body. Although the reason is not fully understood, it is apparent that deoxygenated blood from the pump twin is perfused to the acardiac twin. The acardiac twin grows along with the pump twin, but due to inadequate perfusion it is unable to develop the structures necessary for life, and presents with dramatic deformities. (Wikipedia)

  • Idiobiont parasitoids are those that prevent further development of the host after initial parasitization; typically they attack a host life stage that is immobile (e.g., an egg or pupa), and almost without exception idiobiont parasitoids live outside the host. (Wikipedia)

    See koinobiont parasitoid.

    January 8, 2012

  • Koinobiont parasitoids allow the host to continue its development and often do not kill or consume the host until the host either is about to pupate or become an adult; this therefore typically involves living within an active, mobile host. In turn, koinobionts can be subdivided further into endoparasitoids, which develop inside body of the host, and ectoparasitoids, which develop outside the host body, though the parasitoids frequently are attached or embedded in the host's tissues. (Wikipedia)

  • Parasitic castration is the strategy, by a parasite, of blocking reproduction by its host, completely or in part. For example, Hemioniscus balani, a parasitic castrator of hermaphroditic barnacles, feeds on ovarian fluid, so that its host loses female reproductive ability but still can function as a male. This would be a case of direct parasitic castration (feeding on host gonads). Indirect strategies are also seen such as diverting host energy from gonad development or secreting castrating hormones.

    January 7, 2012

  • Ambush predators or sit-and-wait predators are carnivorous animals that capture prey by stealth or cunning, not by speed or necessarily by strength. These organisms usually hide motionless and wait for prey to come within striking distance. They are often camouflaged, and may be solitary. This mode of predation may be most efficient when a predator cannot move faster than its preferred prey; otherwise, active hunting is more efficient. (Wikipedia)

    January 7, 2012

  • Macroparasites are parasites that are large enough to be seen with the naked eye, in contrast to microparasites. They grow in one host but reproduce by infective stages outside of this host. These generally include ticks, mites, nematodes, flatworms, etc., and can be either external parasites (ectoparasitic) or internal parasites (endoparasitic).

  • Kettle Logic (la logique du chaudron in the original French) is a type of informal fallacy wherein one uses multiple arguments to defend a point, but the arguments themselves are inconsistent.

    The name derives from an example used by Sigmund Freud in The Interpretation of Dreams and in his Jokes and Their Relation to the Unconscious. Freud relates the story that a man who was accused by his neighbour of having returned a kettle in a damaged condition offered three arguments.

    That he had returned the kettle undamaged;

    That it was already damaged when he borrowed it;

    That he had never borrowed it in the first place.

  • From Wikipedia:

    A philosophical zombie or p-zombie in the philosophy of mind and perception is a hypothetical being that is indistinguishable from a normal human being except in that it lacks conscious experience, qualia, or sentience.

    ...

    The unifying idea of the zombie is of a human that has no conscious experience, but one might distinguish various types of zombie used in different thought experiments as follows:

    A behavioral zombie that is behaviorally indistinguishable from a human.

    A neurological zombie that has a human brain and is generally physiologically indistinguishable from a human.

    A soulless zombie that lacks a "soul."

  • Gaslighting is a form of psychological abuse in which false information is presented with the intent of making a victim doubt his or her own memory and perception. It may simply be the denial by an abuser that previous abusive incidents ever occurred, or it could be the staging of bizarre events by the abuser with the intention of disorienting the victim.

    The term "gaslighting" comes from the play Gas Light and its film adaptations. In those works a character uses a variety of tricks, including turning the gas lamps lower than normal, to convince his spouse that she is crazy. Since then it became a colloquial expression which has now also been used in clinical and research literature

  • A taxon that disappears from one or more periods of the fossil record, only to appear again later.

    December 20, 2011

  • In paleontology, an Elvis taxon (plural Elvis taxa) is a taxon which has been misidentified as having re-emerged in the fossil record after a period of presumed extinction, but is not actually a descendant of the original taxon, instead having developed a similar morphology through convergent evolution. This implies the extinction of the original taxon is real, and the two taxa are polyphyletic.

    By contrast, a Lazarus taxon is one which actually is a descendant of the original taxon, and highlights missing fossil records, which may be found later. A zombie taxon is a type of Lazarus taxon sample that was mobile in the time between its original death and its subsequent discovery in a site of younger classification, like, for example, a trilobite that gets eroded out of its Cambrian-aged limestone matrix, and reworked into Miocene-aged siltstone.
