Automata (computation)
An automaton (; plural: automata or automatons) is a relatively self-operating machine, or control mechanism designed to automatically follow a sequence of operations, or respond to predetermined instructions.Automaton – Definition and More from the Free Merriam-Webster Dictionary http://www.merriam-webster.com/dictionary/automaton Some automata, such as bellstrikers in mechanical clocks, are designed to give the illusion to the casual observer that they are operating under their own power. Since long ago, the term is commonly associated with automated puppets that resemble moving humans or animals, built to impress and/or to entertain people. Animatronics are a modern type of automata with electronics, often used for the portrayal of characters in films and in theme park attractions. Etymology The word "automaton" is the latinization of the Ancient Greek , , (neuter) "acting of one's own will". This word was first used by Homer to describe an automatic door opening, or au ...

Automation
Automation describes a wide range of technologies that reduce human intervention in processes, namely by predetermining decision criteria, subprocess relationships, and related actions, as well as embodying those predeterminations in machines. Automation has been achieved by various means including mechanical, hydraulic, pneumatic, electrical, electronic devices, and computers, usually in combination. Complicated systems, such as modern factories, airplanes, and ships typically use combinations of all of these techniques. The benefit of automation includes labor savings, reducing waste, savings in electricity costs, savings in material costs, and improvements to quality, accuracy, and precision. Automation includes the use of various equipment and control systems such as machinery, processes in factories, boilers, and heat-treating ovens, switching on telephone networks, steering, and stabilization of ships, aircraft, and other applications and vehicles with reduced hu ...

Hatshepsut
Hatshepsut (; also Hatchepsut; Egyptian: '' ḥꜣt- špswt'' "Foremost of Noble Ladies"; or Hatasu c. 1507–1458 BC) was the fifth pharaoh of the Eighteenth Dynasty of Egypt. She was the second historically confirmed female pharaoh, after Sobekneferu. (Various other women may have also ruled as pharaohs or at least regents before Hatshepsut, as early as Neithhotep around 1,600 years prior.) Hatshepsut came to the throne of Egypt in 1478 BC. As the principal wife of Thutmose II, Hatshepsut initially ruled as regent to Thutmose III, a son of Thutmose II by another wife and the first male heir. While Thutmose III had inherited the throne at about two years old, Hatshepsut continued to rule by asserting her lineage as the daughter and only child of Thutmose I and his primary wife, Ahmose. Her husband Thutmose II was the son of Thutmose I and a secondary wife named Mutnofret, who carried the title 'King's daughter' and was probably a child of Ahmose I. Hatshepsut and Thutmos ...

Great Library Of Alexandria
The Great Library of Alexandria in Alexandria, Egypt, was one of the largest and most significant libraries of the ancient world. The Library was part of a larger research institution called the Mouseion, which was dedicated to the Muses, the nine goddesses of the arts.Murray, S. A., (2009). The library: An illustrated history. New York: Skyhorse Publishing, p.17 The idea of a universal library in Alexandria may have been proposed by Demetrius of Phalerum, an exiled Athenian statesman living in Alexandria, to Ptolemy I Soter, who may have established plans for the Library, but the Library itself was probably not built until the reign of his son Ptolemy II Philadelphus. The Library quickly acquired many papyrus scrolls, owing largely to the Ptolemaic kings' aggressive and well-funded policies for procuring texts. It is unknown precisely how many such scrolls were housed at any given time, but estimates range from 40,000 to 400,000 at its height. Alexandria came to be regarded ...

Ktesibios
Ctesibius or Ktesibios or Tesibius ( grc-gre, Κτησίβιος; fl. 285–222 BC) was a Greek inventor and mathematician in Alexandria, Ptolemaic Egypt. He wrote the first treatises on the science of compressed air and its uses in pumps (and even in a kind of cannon). This, in combination with his work ''On pneumatics'' on the elasticity of air, earned him the title of "father of pneumatics." None of his written work has survived, including his ''Memorabilia,'' a compilation of his research that was cited by Athenaeus. Ctesibius' most commonly known invention today is a pipe organ (hydraulis), a predecessor of the modern church organ. Inventions Ctesibius was probably the first head of the Museum of Alexandria. Very little is known of his life, but his inventions were well known. It is said (possibly by Diogenes Laërtius) that his first career was as a barber. During his time as a barber, he invented a counterweight-adjustable mirror. Another invention of his included the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prototype
A prototype is an early sample, model, or release of a product built to test a concept or process. It is a term used in a variety of contexts, including semantics, design, electronics, and Software prototyping, software programming. A prototype is generally used to evaluate a new design to enhance precision by system analysts and users. Prototyping serves to provide specifications for a real, working system rather than a theoretical one. In some design workflow models, creating a prototype (a process sometimes called materialization) is the step between the Formal specification, formalization and the evaluation of an idea. A prototype can also mean a typical example of something such as in the use of the derivation 'prototypical'. This is a useful term in identifying objects, behaviours and concepts which are considered the accepted norm and is analogous with terms such as stereotypes and archetypes. The word ''wikt:prototype, prototype'' derives from the Greek language, Greek ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hellenistic Civilization
In Classical antiquity, the Hellenistic period covers the time in History of the Mediterranean region, Mediterranean history after Classical Greece, between the death of Alexander the Great in 323 BC and the emergence of the Roman Empire, as signified by the Battle of Actium in 31 BC and the conquest of Ptolemaic Kingdom, Ptolemaic Egypt the following year. The Ancient Greek word ''Hellas'' (, ''Hellás'') was gradually recognized as the name of Greece, name for Greece, from which the word ''Hellenistic'' was derived. "Hellenistic" is distinguished from "Hellenic" in that the latter refers to Greece itself, while the former encompasses all ancient territories under Greek influence, in particular the East after the conquests of Alexander the Great. After the Macedonian invasion of the Achaemenid Empire in 330 BC and its disintegration shortly after, the Hellenistic kingdoms were established throughout Southwest Asia, south-west Asia (Seleucid Empire, Attalid dynasty, Kingdom of Pe ...

Aphrodite
Aphrodite ( ; grc-gre, Ἀφροδίτη, Aphrodítē; , , ) is an ancient Greek goddess associated with love, lust, beauty, pleasure, passion, and procreation. She was syncretized with the Roman goddess . Aphrodite's major symbols include myrtles, roses, doves, sparrows, and swans. The cult of Aphrodite was largely derived from that of the Phoenician goddess Astarte, a cognate of the East Semitic goddess Ishtar, whose cult was based on the Sumerian cult of Inanna. Aphrodite's main cult centers were Cythera, Cyprus, Corinth, and Athens. Her main festival was the Aphrodisia, which was celebrated annually in midsummer. In Laconia, Aphrodite was worshipped as a warrior goddess. She was also the patron goddess of prostitutes, an association which led early scholars to propose the concept of "sacred prostitution" in Greco-Roman culture, an idea which is now generally seen as erroneous. In Hesiod's ''Theogony'', Aphrodite is born off the coast of Cythera from the foam (, ) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mercury (element)
Mercury is a chemical element with the symbol Hg and atomic number 80. It is also known as quicksilver and was formerly named hydrargyrum ( ) from the Greek words, ''hydor'' (water) and ''argyros'' (silver). A heavy, silvery d-block A block of the periodic table is a set of elements unified by the atomic orbitals their valence electrons or vacancies lie in. The term appears to have been first used by Charles Janet. Each block is named after its characteristic orbital: s-blo ... element, mercury is the only metallic element that is known to be liquid at standard temperature and pressure; the only other element that is liquid under these conditions is the halogen bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature. Mercury occurs in deposits throughout the world mostly as cinnabar (mercuric sulfide). The red pigment vermilion is obtained by Mill (grinding), grinding natural cinnabar or synthetic mercuric sulfide. Mercury is used in ...

Daedalus
In Greek mythology, Daedalus (, ; Greek: Δαίδαλος; Latin: ''Daedalus''; Etruscan: ''Taitale'') was a skillful architect and craftsman, seen as a symbol of wisdom, knowledge and power. He is the father of Icarus, the uncle of Perdix, and possibly also the father of Iapyx. Among his most famous creations are the wooden cow for Pasiphaë, the Labyrinth for King Minos of Crete which imprisoned the Minotaur, and wings that he and his son Icarus used to escape Crete. It was during this escape that Icarus did not heed his father's warnings and flew too close to the sun; the wax holding his wings together melted and Icarus fell to his death. Epigraphic evidence The name ''Daidalos'' appears to be attested in Linear B, a writing system used to record Mycenaean Greek. The name appears in the form ''da-da-re-jo-de'', possibly referring to a sanctuary. Family Daedalus's parentage was supplied as a later addition, with various authors attributing different parents to him. His fat ...

Aristotle
Aristotle (; grc-gre, Ἀριστοτέλης ''Aristotélēs'', ; 384–322 BC) was a Greek philosopher and polymath during the Classical period in Ancient Greece. Taught by Plato, he was the founder of the Peripatetic school of philosophy within the Lyceum and the wider Aristotelian tradition. His writings cover many subjects including physics, biology, zoology, metaphysics, logic, ethics, aesthetics, poetry, theatre, music, rhetoric, psychology, linguistics, economics, politics, meteorology, geology, and government. Aristotle provided a complex synthesis of the various philosophies existing prior to him. It was above all from his teachings that the West inherited its intellectual lexicon, as well as problems and methods of inquiry. As a result, his philosophy has exerted a unique influence on almost every form of knowledge in the West and it continues to be a subject of contemporary philosophical discussion. Little is known about his life. Aristotle was born in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phaiakian
Scheria or Scherie (; grc, Σχερία or ), also known as Phaeacia () or Faiakia was a region in Greek mythology, first mentioned in Homer's ''Odyssey'' as the home of the Phaeacians and the last destination of Odysseus in his 10-year journey before returning home to Ithaca. It is one of the earliest descriptions of a utopia. From Ogygia to Scheria (Odysseus) Before leaving Ogygia, Odysseus builds a raft and sails eastwards, instructed by Calypso to navigate using the stars as a celestial reference point. On the eighteenth day appear the shadowy mountains of the land of the Phaeacians, that looked like a ''shield'' in the misty deep. Poseidon spots his raft and seeking vengeance for his son Polyphemus who was blinded by Odysseus, produces a storm that torments Odysseus. After three days of struggle with the waves, he is finally washed up on Scheria. Odysseus meets Nausicaa Meanwhile, the goddess Athena sneaks into the palace, disguised as a sea-captain's daughter, and instru ...
