Archimedes
Archimedes of Syracuse (;; ) was a Greek mathematician, physicist, engineer, astronomer, and inventor from the ancient city of Syracuse in Sicily. Although few details of his life are known, he is regarded as one of the leading scientists in classical antiquity. Considered the greatest mathematician of ancient history, and one of the greatest of all time,* * * * * * * * * * Archimedes anticipated modern calculus and analysis by applying the concept of the infinitely small and the method of exhaustion to derive and rigorously prove a range of geometrical theorems. These include the area of a circle, the surface area and volume of a sphere, the area of an ellipse, the area under a parabola, the volume of a segment of a paraboloid of revolution, the volume of a segment of a hyperboloid of revolution, and the area of a spiral.

The Once And Future King
''The Once and Future King'' is a collection of fantasy novels by T. H. White about the legend of King Arthur. It is loosely based upon the 1485 work '' Le Morte d'Arthur'' by Sir Thomas Malory. It was first published in 1958 as a collection of shorter novels published from 1938 to 1940, with some new or amended material. The title refers to a legend that Arthur will one day return as king. Summary Most of the book takes place in "Gramarye", the name that White gives to Britain, and chronicles the youth and education of King Arthur, his rule as a king, and the romance between Sir Lancelot and Queen Guinevere. Arthur is supposed to have lived in the 5th and 6th centuries, but the book is set around the 14th century. Arthur is portrayed as an Anglo-Norman rather than a Briton; White refers to the actual monarchs of that period as "mythical". The book ends immediately before Arthur's final battle against his illegitimate son Mordred. White acknowledged that his book's source ma ...

Archimedes (bryozoan)
''Archimedes'' is a genus of bryozoans belonging to the family Fenestellidae. The first use of the term "Archimedes" in relation to this genus was in 1838. Etymology This genus of bryozoans is named ''Archimedes'' because of its corkscrew shape, in analogy to the Archimedes' screw, a type of water pump which inspired modern ship propellers in turn named after the ancient greek polymath. These forms are common as fossils but they have been extinct since the Permian. Species *''Archimedes orientalis'' Schulga-Nesterenko 1936 *''Archimedes regina'' Crockford 1947 *''Archimedes stuckenbergi ''Nikiforova 1938 Fossil range These bryozoans lived from the Carboniferous period (Tournaisian age) to the Permian period (Leonard age) (345.3 to 268.0 Ma), when this genus became extinct.Sepkoski, JacSepkoski's Online Genus Database - Bryozoa/ref> Description ''Archimedes'' is a genus of fenestrate bryozoans with a calcified skeleton of a delicate spiral-shaped mesh that was thickened ne ...

Archimedes (rocket Engine)
Archimedes is a liquid-fuel rocket engine burning liquid oxygen and liquid methane in an oxidizer-rich staged combustion cycle. It is designed by aerospace company Rocket Lab for its Neutron rocket. History Archimedes was presented on December 2, 2021 in a webcast by Rocket Lab CEO Peter Beck. It was presented as a fully reusable, gas generator engine using LOX and methane as propellant, a departure from the company's previous Rutherford, which is electrically pump fed. He then stated that it had a thrust of and 320 seconds of specific impulse. The same day, the Neutron page on Rocket Lab's website was updated specifying the thrust of the seven Archimedes used on the first stage as at sea level and a maximum thrust of and the upper stage's single vacuum optimized Archimedes at . It is expected to have its first hot-fire test during 2022. In an interview published on CNBC website, Mr. Beck stated that Archimedes would be manufactured in New Zealand and its very simple design ...

SS Archimedes
SS ''Archimedes'' was a steamship built in Britain in 1839. She was the world's first steamship to be driven successfully by a screw propeller. ''Archimedes'' had considerable influence on ship development, encouraging the adoption of screw propulsion by the Royal Navy, in addition to her influence on commercial vessels. She also had a direct influence on the design of another innovative vessel, Isambard Kingdom Brunel's , then the world's largest ship and the first screw-propelled steamship to cross the Atlantic Ocean. Background The principle of moving water with a screw has been known since the invention of the Archimedes' screw, named after Archimedes of Syracuse who lived in the 3rd century BC. It was not until the 18th century however, and the invention of the steam engine, that a practical means of delivering effective power to a marine screw propulsion system became available, but initial attempts to build such a vessel met with failure. In 1807, the world's first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archimedes (1797)
''Archimedes'' was launched at Sunderland in 1796 or 1797. She traded between England and the Baltic until the British government chartered her as a transport .

Career ''Archimedes'' first appeared in '' Lloyd's Register'' (''LR'') in 1797 with J.Hill, master and owner, and trade Liverpool–London. She then traded between England and the Baltic. ''Lloyd's List'' (''LL'') reported on 1 June 1798 that ''Archimedes'', Howard, master, had been taken while sailing from Haambro to Petersburg. However, ''Lloyd's List ''Lloyd's List'' is one of the world's oldest continuously running journals, having provided weekly shipping news in London as early as 1734.

GNU Archimedes
Archimedes is a TCAD package for use by engineers to design and simulate submicron and mesoscopic semiconductor devices. Archimedes is free software and thus it can be copied, modified and redistributed under GPL. Archimedes uses the Ensemble Monte Carlo method and is able to simulate physics effects and transport for electrons and heavy holes in Silicon, Germanium, GaAs, InSb, AlSb, AlAs, AlxInxSb, AlxIn(1-x)Sb, AlP, AlSb, GaP, GaSb, InP and their compounds (III-V semiconductor materials), along with Silicon Oxide. Applied and/or self-consistent electrostatic and magnetic fields are handled with the Poisson and Faraday equations. The GNU project has announced in May 2012 that the software package ''Aeneas'' will be substituted by Archimedes, making this one the GNU package for Monte Carlo semiconductor devices simulations. Introduction Archimedes is the GNU package for semiconductor device simulations that has been released for the first time on 2005 under GPL. It has bee ...

Claw Of Archimedes
The Claw of Archimedes ( grc, Ἁρπάγη, translit=harpágē, lit=snatcher; also known as the iron hand) was an ancient weapon devised by Archimedes to defend the seaward portion of Syracuse's city wall against amphibious assault. Although its exact nature is unclear, the accounts of ancient historians seem to describe it as a sort of crane equipped with a grappling hook that was able to drop an attacking ship partly down in to the water, then either cause the ship to capsize or suddenly drop it. It was dropped onto enemy ships, which would then swing on to defensive forces and destroy them. These machines featured prominently during the Second Punic War in 214 BC, when the Roman Republic attacked Syracuse with a fleet of 60 quinqueremes under Marcus Claudius Marcellus. When the Roman fleet approached the city walls under cover of darkness, the machines were deployed, sinking many ships and throwing the attack into confusion. Historians such as Livy attributed heavy Ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acorn Archimedes
Acorn Archimedes is a family of personal computers designed by Acorn Computers of Cambridge, Cambridge, England. The systems are based on Acorn's own ARM architecture processors and the proprietary operating systems Arthur and RISC OS. The first models were introduced in 1987, and systems in the Archimedes family were sold until the mid-1990s. ARM's Reduced instruction set computer, RISC design, a 32-bit CPU (using 26-bit addressing), running at 8 Hertz, MHz, was stated as achieving 4.5+ Million instructions per second, MIPS, which provided a significant upgrade from 8-bit home computers, such as Acorn's previous machines. Claims of being the fastest micro in the world and running at 18 MIPS were also made during tests. Two of the first models—the A305 and A310—were given the BBC branding, with BBC Worldwide, BBC Enterprises regarding the machines as "a continuing part of the original computer literacy project". Dissatisfaction with the branding arrangement was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
