Portable Hole
In various works of fiction, a portable hole is a two-dimensional device that can be used to contravene the laws of physics by creating a passage through a solid surface, through which characters can move. Notable uses The 1955 '' Looney Tunes'' cartoon, '' The Hole Idea'', presents a fictional account in which Calvin Q. Calculus invents the device. The theme was repeated in The Beatles' 1968 movie, ''Yellow Submarine'', where Ringo picks up a hole from the Sea of Holes, stores it in his pocket, and uses it later to release Sgt. Pepper's Band from captivity. In 1988, ''Who Framed Roger Rabbit'' again used a portable hole as a plot device. Detective Eddie Valiant is able to escape being crushed by a steamroller by using one, echoing the 1955 ''Looney Tunes'' gag. In the ''Dungeons & Dragons'' fantasy role-playing game, a portable hole is a circle of cloth made from phase spider webs, strands of ether and beams of starlight. When deployed, it creates an extradimensional space ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Looney Tunes
''Looney Tunes'' is an American Animated cartoon, animated comedy short film series produced by Warner Bros. starting from 1930 to 1969, concurrently with its partner series ''Merrie Melodies'', during the golden age of American animation.Looney Tunes . ''www.bcdb.com'', April 12, 2012 Then some new cartoons were produced from the late 1980s to the mid 2010s as well as other made productions beginning in 1972. The two series introduced a large List of Looney Tunes and Merrie Melodies characters, cast of characters, including Bugs Bunny, Daffy Duck, and Porky Pig. The term ''Looney Tunes'' has since been expanded to also refer to the characters themselves. ''Looney Tunes'' and ''Merrie Melodies'' were initially produced by Leon Schlesinger and animators Harman and Ising, Hugh Harman and Rudolph Ising from 1930 to 1933.

Gramicidin
Gramicidin, also called gramicidin D, is a mix of ionophoric antibiotics, gramicidin A, B and C, which make up about 80%, 5%, and 15% of the mix, respectively. Each has 2 isoforms, so the mix has 6 different types of gramicidin molecules. They can be extracted from ''Brevibacillus brevis'' soil bacteria. Gramicidins are linear peptides with 15 amino acids. This is in contrast to unrelated gramicidin S, which is a cyclic peptide. Medical uses Gramicidins work as antibiotics against gram-positive bacteria like ''Bacillus subtilis'' and ''Staphylococcus aureus'', but not well against gram-negative ones like '' E. coli''. Gramicidins are used in medicinal lozenges for sore throat and in topical medicines to treat infected wounds. Gramicidins are often mixed with other antibiotics like tyrocidine and antiseptics. Gramicidins are also used in eye drops for bacterial eye infections. In drops, they are often mixed with other antibiotics like polymyxin B or neomycin. Multiple antibioti ...

Portal (video Game)
''Portal'' is a 2007 Puzzle video game, puzzle-platform game developed and published by Valve Corporation, Valve. It was released in a Product bundling, bundle, ''The Orange Box,'' for Windows, Xbox 360 and PlayStation 3, and has been since ported to other systems, including Mac OS X, Linux, Android (operating system), Android (via Nvidia Shield), and Nintendo Switch. ''Portal'' consists primarily of a series of puzzles that must be solved by teleporting the player's character and simple objects using "the Aperture Science Handheld Portal Device", often referred to as the "portal gun", a device that can create inter-spatial portals between two flat planes. The player-character, Chell (Portal), Chell, is challenged and taunted by an artificial intelligence named GLaDOS (Genetic Lifeform and Disk Operating System) to complete each puzzle in the Aperture Science Enrichment Center using the portal gun with the promise of receiving cake when all the puzzles are completed.

Wormhole
A wormhole (Einstein-Rosen bridge) is a hypothetical structure connecting disparate points in spacetime, and is based on a special Solutions of the Einstein field equations, solution of the Einstein field equations. A wormhole can be visualized as a tunnel with two ends at separate points in spacetime (i.e., different locations, different points in time, or both). Wormholes are consistent with the General relativity, general theory of relativity, but whether wormholes actually exist remains to be seen. Many scientists postulate that wormholes are merely projections of a Four-dimensional space, fourth spatial dimension, analogous to how a two-dimensional (2D) being could experience only part of a three-dimensional (3D) object. Theoretically, a wormhole might connect extremely long distances such as a billion light years, or short distances such as a few meters, or different points in time, or even multiverse, different universes. In 1995, Matt Visser suggested there may be ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teleportation In Fiction
Teleportation is the theoretical transfer of matter and/or energy from one point to another without traversing the physical space between them. It is a common subject in science fiction and fantasy literature, film, video games, and television. In some situations, teleporting is presented as time traveling across space. The use of matter transmitters in science fiction originated at least as early as the 19th century. An early example of scientific teleportation (as opposed to magical or spiritual teleportation) is found in the 1897 novel ''To Venus in Five Seconds'' by Fred T. Jane. Jane's protagonist is transported from a strange-machinery-containing gazebo on Earth to planet Venus. A common fictional device for teleportation is a Wormholes in fiction, "wormhole". In video games, the instant teleportation of a player character may be referred to as a warp (video games), warp.

Bag Of Holding
In the ''Dungeons & Dragons'' fantasy role-playing game, a magic item is any object that has magic powers that inherit it. These items may act on their own or be the tools of the character possessing them. Magic items have been prevalent in the game in every edition and setting, from the original edition in 1974 until the modern fifth edition. In addition to jewels and gold coins, they form part of the treasure that the players often seek in a dungeon. Magic items are generally found in treasure hoards, or recovered from fallen opponents; sometimes, a powerful or important magic item is the object of a quest. Development 1st edition ''Advanced Dungeons & Dragons'' In the first edition, all artifacts are classed as miscellaneous magic items, even ones that are weapons, armor, or rings. Each artifact has a certain number of Minor, Major, and Prime Powers, and of Minor, Major, and Side Effects which trigger when the item is acquired, or its Major and Prime Powers are used.

Hammerspace
Hammerspace (also known as malletspace) is a fan-envisioned extradimensional, instantly accessible storage area in fiction, which is used to explain how animated, comic, and game characters can produce objects out of thin air. Typically, when multiple items are available, the desired item is available on the first try or within a handful of tries. This phenomenon dates back to early Warner Bros.' '' Looney Tunes''/'' Merrie Melodies'' and MGM cartoons produced during the Golden Age of American animation. For example, in the 1943 Tex Avery short ''What's Buzzin' Buzzard'', a starving vulture prepares to cook his friend by pulling an entire kitchen's worth of appliances out of thin air. Origins The phenomenon of a character producing plot-dependent items seemingly out of thin air dates back to the beginning of animated shorts during The Golden Age of American animation. Warner Bros. Cartoon characters are particularly well known for often pulling all sorts of things— hammers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ben Vautier
Ben Vautier, also known simply as Ben (born 18 July 1935 in Naples, Italy), is a French artist. Vautier lives and works in Nice, where he ran a record shop called ''Magazin'' between 1958 and 1973. Biography Benjamin Vautier was born on 18 July 1935 in Naples, Italy to a French family. He is the great-grandson of the Swiss painter (1829-1898). He discovered Yves Klein and the Nouveau Réalisme in the 1950s, but he became quickly interested in the French dada artist Marcel Duchamp and the music of John Cage. In 1959, Vautier founded the journal ''Ben Dieu''. In 1960, he had his first one-man show, ''Rien et tout'' in ''Laboratoire 32''. Ben joined George Maciunas in the Fluxus artistic movement, in October 1962. He is also active in Mail-Art and is mostly known for his text-based paintings or écritures began in 1953, with his work ''Il faut manger. Il faut dormir''.

Lipid Bilayer
The lipid bilayer (or phospholipid bilayer) is a thin polar membrane made of two layers of lipid molecules. These membranes are flat sheets that form a continuous barrier around all cells. The cell membranes of almost all organisms and many viruses are made of a lipid bilayer, as are the nuclear membrane surrounding the cell nucleus, and membranes of the membrane-bound organelles in the cell. The lipid bilayer is the barrier that keeps ions, proteins and other molecules where they are needed and prevents them from diffusing into areas where they should not be. Lipid bilayers are ideally suited to this role, even though they are only a few nanometers in width, because they are impermeable to most water-soluble (hydrophilic) molecules. Bilayers are particularly impermeable to ions, which allows cells to regulate salt concentrations and pH by transporting ions across their membranes using proteins called ion pumps. Biological bilayers are usually composed of amphiphilic phosphol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dimer (chemistry)
A dimer () ('' di-'', "two" + ''-mer'', "parts") is an oligomer consisting of two monomers joined by bonds that can be either strong or weak, covalent or intermolecular. Dimers also have significant implications in polymer chemistry, inorganic chemistry, and biochemistry. The term ''homodimer'' is used when the two molecules are identical (e.g. A–A) and ''heterodimer'' when they are not (e.g. A–B). The reverse of dimerization is often called dissociation. When two oppositely charged ions associate into dimers, they are referred to as ''Bjerrum pairs'', after Niels Bjerrum. Noncovalent dimers Anhydrous carboxylic acids form dimers by hydrogen bonding of the acidic hydrogen and the carbonyl oxygen. For example, acetic acid forms a dimer in the gas phase, where the monomer units are held together by hydrogen bonds. Under special conditions, most OH-containing molecules form dimers, e.g. the water dimer. Excimers and exciplexes are excited structures with a short lifetime. ...

Peptide
Peptides (, ) are short chains of amino acids linked by peptide bonds. Long chains of amino acids are called proteins. Chains of fewer than twenty amino acids are called oligopeptides, and include dipeptides, tripeptides, and tetrapeptides. A polypeptide is a longer, continuous, unbranched peptide chain. Hence, peptides fall under the broad chemical classes of biological polymers and oligomers, alongside nucleic acids, oligosaccharides, polysaccharides, and others. A polypeptide that contains more than approximately 50 amino acids is known as a protein. Proteins consist of one or more polypeptides arranged in a biologically functional way, often bound to ligands such as coenzymes and cofactors, or to another protein or other macromolecule such as DNA or RNA, or to complex macromolecular assemblies. Amino acids that have been incorporated into peptides are termed residues. A water molecule is released during formation of each amide bond.. All peptides except cyclic pep ...
