Ant Farm
A formicarium or ant farm is a vivarium which is designed primarily for the study of ant colonies and how ants behave. Those who study ant behavior are known as myrmecologists. History The formicarium was invented by Charles Janet, a French entomologist and polymath, who had the idea of reducing the three dimensions of an ant nest to the virtual two dimensions between two panes of glass. His design was exhibited in the Exposition Universelle (1900) in Paris. Janet's invention was recognized by his promotion to Chevalier (Knight) of the Legion of Honour, but he did not obtain a patent for, nor attempt to market his creation. The first commercially sold formicarium was introduced around 1929 by Frank Eugene Austin (1873–1964), an inventor and professor at the Thayer School of Engineering at Dartmouth College. Austin received a patent for his formicarium on June 16, 1931, as well as further patents for its continued development. Austin included whimsical painted or wooden s ...

Miners
A miner is a person who extracts ore, coal, chalk, clay, or other minerals from the earth through mining. There are two senses in which the term is used. In its narrowest sense, a miner is someone who works at the rock face; cutting, blasting, or otherwise working and removing the rock. In a broader sense, a "miner" is anyone working within a mine, not just a worker at the rock face. Mining is one of the most dangerous trades in the world. In some countries, miners lack social guarantees and in case of injury may be left to cope without assistance. In regions with a long mining tradition, many communities have developed cultural traditions and aspects specific to the various regions, in the forms of particular equipment, symbolism, music, and the like. Roles Different functions of the individual miner. Many of the roles are specific to a type of mining, such as coal mining. Roles considered to be "miners" in the narrower sense have included: * Hewer (also known as "cake" or " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mexican Jumping Bean
Mexican jumping beans (also known as ' in Spanish) are seed pods that have been inhabited by the larva of a small moth (''Cydia saltitans'') and are native to Mexico. The "bean" is usually tan to brown. They are from the shrub '' Sebastiania pavoniana'', often also referred to as "jumping bean". However, they are not related to actual beans (legume plants), but rather to spurges. The beans are considered non-toxic but are not generally eaten. In the spring, when the shrub is flowering, moths lay their eggs on the shrub’s hanging seedpods. When the eggs hatch, tiny larvae bore into the immature green pods and begin to devour the seeds. The pods ripen, fall to the ground and separate into three smaller segments, and those segments are called Mexican jumping beans. As the tiny larvae inside curl up and uncurl, they hit the capsule’s wall with their heads – and the bean jumps. It’s been observed that they move more as temperatures rise, the larva eats away the inside of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SimAnt
''SimAnt: The Electronic Ant Colony'' is a 1991 life simulation video game by Maxis and the company's third product, focusing on ants. It was designed by Will Wright. In 1992, it was named "Best Simulation Game" at the Software Publishers Association's Codie awards. ''SimAnt'' was re-released in 1993 as part of the ''SimClassics Volume 1'' compilation alongside '' SimCity Classic'' and ''SimLife'' for PC, Mac and Amiga. In 1996 SimAnt alongside several of Maxis' simulation games were re-released under the ''Maxis Collector Series'' with greater compatibility with Windows 95 and differing box art, including the addition of ''Classics'' beneath the title. Gameplay The game is a simulation of an ant colony. Wright was inspired by E. O. Wilson's study of ant colonies. The game consists of three modes: a Quick Game, a Full Game, and an Experimental Game. It was released for the IBM PC, Amiga, Macintosh, and Super NES. The Super NES version adds eight scenarios, where the goal in ...

Sea-Monkeys
Sea-Monkeys is a marketing term for brine shrimp (''Artemia'') sold as novelty aquarium pets. Developed in the United States in 1957 by Harold von Braunhut, they are sold as eggs intended to be added to water, and almost always come bundled in a kit of three pouches and instructions. Sometimes a small tank and additional pouches are included. The product was heavily marketed in the 1960s and 70s, especially in comic books, and remains a presence in popular culture. History Ant farms had been popularized in 1956 by Milton Levine. Harold von Braunhut invented a brine-shrimp-based product the next year, 1957. Von Braunhut collaborated with a marine biologist, Anthony D'Agostino, to develop the proper mix of nutrients and chemicals in dry form that could be added to plain tap water to create a suitable habitat for the shrimp to thrive. Von Braunhut was granted a patent for this process on July 4, 1972. They were initially called "Instant Life" and sold for $0.49, but von Braunh ...

Instant Fish
In physics and the philosophy of science, instant refers to an infinitesimal interval in time, whose passage is instantaneous. In ordinary speech, an instant has been defined as "a point or very short space of time," a notion deriving from its etymological source, the Latin verb ''instare'', from ''in-'' + ''stare'' ('to stand'), meaning 'to stand upon or near.' The continuous nature of time and its infinite divisibility was addressed by Aristotle in his ''Physics'', where he wrote on Zeno's paradoxes. The philosopher and mathematician Bertrand Russell was still seeking to define the exact nature of an instant thousands of years later. , the smallest time interval certify in regulated measurements is on the order of 397 zeptoseconds (397 × 10−21 seconds). See also * Infinitesimal * Present The present (or here'' and ''now) is the time that is associated with the events perceived directly and in the first time, not as a recollection (perceived more than once) or a specul ...

Ant Robotics
Ant robotics is a special case of swarm robotics. Swarm robots are simple (and hopefully, therefore cheap) robots with limited sensing and computational capabilities. This makes it feasible to deploy teams of swarm robots and take advantage of the resulting fault tolerance and parallelism. Swarm robots cannot use conventional planning methods due to their limited sensing and computational capabilities. Thus, their behavior is often driven by local interactions. Ant robots are swarm robots that can communicate via markings, similar to ants that lay and follow pheromone trails. Some ant robots use long-lasting trails (either regular trails of a chemical substance or smart trails of transceivers). Others use short-lasting trails including heat and alcohol. Others even use virtual trails. Invention In 1991, American electrical engineer James McLurkin was the first to conceptualize the idea of "robot ants" while working at the MIT Computer Science and Artificial Intelligence Laboratory ...

Ant-keeping
Ant-keeping (or ant keeping) is a hobby involving the capture, care, and observation of ants and ant colonies. It is a form of lay myrmecology. History Keeping ants as pets has been a common hobby since the mass-marketed Uncle Milton's Ant Farm achieved commercial success in the late 1950s, though these ant farms did not include a queen ant for legal reasons. With exception of '' Pogonomyrmex occidentalis'', U.S. Federal law prohibits shipping live queen ants of other species (and other “plant pests”) in interstate commerce. Reasons for ant-keeping Ant keepers may choose to keep ants in captivity for the purpose of documenting ant behavior (in the case of an ant species which is difficult to observe in the wild). This field of study is called myrmecology. Ant keepers may also choose to keep ants as a casual hobby; i.e., as pets. People who keep ants may also keep them for scientific purposes and experiments. Starting a colony There are differing methods of starting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moat
A moat is a deep, broad ditch, either dry or filled with water, that is dug and surrounds a castle, fortification, building or town, historically to provide it with a preliminary line of defence. In some places moats evolved into more extensive water defences, including natural or artificial lakes, dams and sluices. In older fortifications, such as hillforts, they are usually referred to simply as ditches, although the function is similar. In later periods, moats or water defences may be largely ornamental. They could also act as a sewer. Historical use Ancient Some of the earliest evidence of moats has been uncovered around ancient Egyptian castles. One example is at Buhen, a castle excavated in Nubia. Other evidence of ancient moats is found in the ruins of Babylon, and in reliefs from ancient Egypt, Assyria, and other cultures in the region. Evidence of early moats around settlements has been discovered in many archaeological sites throughout Southeast Asia, includin ...

Polytetrafluoroethylene
Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications. It is one of the best-known and widely applied PFAS. The commonly known brand name of PTFE-based composition is Teflon by Chemours, a spin-off from DuPont, which originally discovered the compound in 1938. Polytetrafluoroethylene is a fluorocarbon solid, as it is a high- molecular-weight polymer consisting wholly of carbon and fluorine. PTFE is hydrophobic: neither water nor water-containing substances wet PTFE, as fluorocarbons exhibit only small London dispersion forces due to the low electric polarizability of fluorine. PTFE has one of the lowest coefficients of friction of any solid. Polytetrafluoroethylene is used as a non-stick coating for pans and other cookware. It is non-reactive, partly because of the strength of carbon–fluorine bonds, so it is often used in containers and pipework for reactive and corrosive chemicals. Where used as a lubricant ...

Formica Cunicularia
''Formica cunicularia'' is a species of ant found all over Europe. They are especially common in western Europe and southern England, but they can be found from southern Scandinavia to northern Africa and from Portugal to the Urals. In England, Donisthorpe records the species as having occurred as far north as Bewdley in Worcestershire.Donisthorpe, Horace St. John Kelly. (1915)British Ants: Their Life-History and Classification. Reprinted 2013, London: Forgotten Books. pp. 318–320. In ''Formica cunicularia'', the worker is an ashy grey black color and is usually 4.0–6.5 mm long. The males are found to have a uniformly dark body and are 8.0–9.0 mm long. The queen is yellowish red to dark black and is 7.5–9.0 mm. Habitat ''F. cunicularia'' has habitat ranging from open to relatively cluttered to visually rich. In Finland, Albrecht found that all nests were small, with single entrances in dry, hot environments with low vegetation. They nest under stones or in ...
