Starfish
Starfish or sea stars are star-shaped echinoderms belonging to the class Asteroidea (). Common usage frequently finds these names being also applied to ophiuroids, which are correctly referred to as brittle stars or basket stars. Starfish are also known as asteroids due to being in the class Asteroidea. About 1,900 species of starfish live on the seabed in all the world's oceans, from warm, tropical zones to frigid, polar regions. They are found from the intertidal zone down to abyssal depths, at below the surface. Starfish are marine invertebrates. They typically have a central disc and usually five arms, though some species have a larger number of arms. The aboral or upper surface may be smooth, granular or spiny, and is covered with overlapping plates. Many species are brightly coloured in various shades of red or orange, while others are blue, grey or brown. Starfish have tube feet operated by a hydraulic system and a mouth at the centre of the oral or lower surface. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eversion (kinesiology)
Motion, the process of movement, is described using specific anatomical terms. Motion includes movement of organs, joints, limbs, and specific sections of the body. The terminology used describes this motion according to its direction relative to the anatomical position of the body parts involved. Anatomists and others use a unified set of terms to describe most of the movements, although other, more specialized terms are necessary for describing unique movements such as those of the hands, feet, and eyes. In general, motion is classified according to the anatomical plane it occurs in. ''Flexion'' and ''extension'' are examples of ''angular'' motions, in which two axes of a joint are brought closer together or moved further apart. ''Rotational'' motion may occur at other joints, for example the shoulder, and are described as ''internal'' or ''external''. Other terms, such as ''elevation'' and ''depression'', describe movement above or below the horizontal plane. Many anatomica ...

Eversion (video Game)
''Eversion'' is a platform game by British indie studio Zaratustra Productions for Microsoft Windows. It was originally released as freeware in 2008, with a high-definition remake being released on Steam in 2010. Gameplay ''Eversion'' is a side-scrolling platform game in which the player's flower-like avatar is tasked with collecting gems scattered throughout the stages and reaching the flag that marks the stage's end. At specific points, the player may activate an "eversion" ability that changes the state of the stage by removing obstacles and creating platforms, making it a necessary tool for progress. The game includes a bare-bones narrative centering on the rescue of a captured princess and initially presents a colorful and whimsical atmosphere. However, as use of the eversion ability increases, the visuals become unsettling and nightmarish. As such, a note indicating that the game is not "for children or those of a nervous disposition" is posted on the official website and wit ...

Sea Cucumber
Sea cucumbers are echinoderms from the class Holothuroidea (). They are marine animals with a leathery skin and an elongated body containing a single, branched gonad. Sea cucumbers are found on the sea floor worldwide. The number of holothurian () species worldwide is about 1,717, with the greatest number being in the Asia-Pacific region. Many of these are gathered for human consumption and some species are cultivated in aquaculture systems. The harvested product is variously referred to as '' trepang'', ''namako'', ''bêche-de-mer'', or ''balate''. Sea cucumbers serve a useful role in the marine ecosystem as they help recycle nutrients, breaking down detritus and other organic matter, after which bacteria can continue the decomposition process. Like all echinoderms, sea cucumbers have an endoskeleton just below the skin, calcified structures that are usually reduced to isolated microscopic ossicles (or sclerietes) joined by connective tissue. In some species these can sometim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sphere Eversion
In differential topology, sphere eversion is the process of turning a sphere inside out in a three-dimensional space (the word '' eversion'' means "turning inside out"). Remarkably, it is possible to smoothly and continuously turn a sphere inside out in this way (with possible self-intersections) without cutting or tearing it or creating any crease. This is surprising, both to non-mathematicians and to those who understand regular homotopy, and can be regarded as a veridical paradox; that is something that, while being true, on first glance seems false. More precisely, let :f\colon S^2\to \R^3 be the standard embedding; then there is a regular homotopy of immersions :f_t\colon S^2\to \R^3 such that ''ƒ''0 = ''ƒ'' and ''ƒ''1 = −''ƒ''. History An existence proof for crease-free sphere eversion was first created by . It is difficult to visualize a particular example of such a turning, although some digital animations have been produced that ...

Alastair Reynolds
Alastair Preston Reynolds (born 13 March 1966) is a Welsh science fiction author. He specialises in hard science fiction and space opera. He spent his early years in Cornwall, moved back to Wales before going to Newcastle University, where he studied physics and astronomy. Afterwards, he earned a PhD in astrophysics from the University of St Andrews. In 1991, he moved to Noordwijk in the Netherlands where he met his wife Josette (who is from France). There, he worked for the European Space Research and Technology Centre (part of the European Space Agency) until 2004 when he left to pursue writing full-time. He returned to Wales in 2008 and lives near Cardiff. Works Reynolds wrote his first four published science fiction short stories while still a graduate student, in 1989–1991; they appeared in 1990–1992, his first sale being to '' Interzone''. In 1991 Reynolds graduated and moved from Scotland to the Netherlands to work at ESA. He then started spending much of his writing ...
