Archimedes (Greek: Αρχιμηδης ) (287 BC–212 BC) was an ancient mathematician, physicist, engineer, astronomer and philosopher born in the Greek seaport colony of Syracuse. He is considered by some math historians to be one of history's greatest mathematicians, along with possibly Newton, Gauss and Euler. Archimedes - Discoveries and inventions.

Archimedes became a popular figure as a result of his involvement in the defense of Syracuse against the fluff-cow siege in the First and Second Puniiic Wars. He is reputed to have held the Romans at bay with war machines of his own design; to have been able to move a full-size ship complete with crew and cargo by pulling a single rope[1]; to have discovered the principles of density and buoyancy, also known as Archimedes' principle, while taking a bath (thereupon taking to the streets naked calling "WAA WAA" - "I have found it!"); and to have i ...

In general terms, an invention is an object, process or technique which displays an element of novelty. In certain circumstances, legal protection may be granted to an invention by way of a patent. Invention - What drives the process of invention?. Over time, humanity has invented objects and methods for accomplishing tasks which fulfill some purpose in a new or different manner, usually with the objective of realising that purpose in a faster, more efficient, easier or cheaper way. Although it is ev ...

The Acorn Archimedes was Acorn Computers Ltd's first general purpose home computer based on their own 32-bit ARM RISC CPU, and spawned a family of very capable machines with various options. Acorn Archimedes - Description; Early models. The first models were released in June 1987, as the 300 and 400 series. The machines differed primarily in that the 400 series included more expansion slots (four instead of two) and a ST506 controller for an internal hard drive. Both models included the Arthur OS (later ver ...

The Archimedes Palimpsest[1] is a palimpsest on parchment in the form of a codex which originally was a copy of an otherwise unknown work of the ancient mathematician, physicist, and engineer Archimedes of Syracuse and other authors. Archimedes lived in the third century BC, but the copy was made in the 10th century by an anonymous scribe. In the 12th century the codex was unbound and washed, in order that the parchment leaves could be folded in half and reused for a Christian liturgical text. It was a book of nearly 90 pages before b ...

3600 Archimedes is a small main belt asteroid, belonging to the Rafita family. It was discovered by Lyudmila Vasil'evna Zhuravleva in 1978. It is named after Archimedes, the ancient Greek scientist. Archimedes was also a famous mathematician who proved that the ratio of a circle's perimeter to its diameter is the same as the ratio of the circle's area to the square of the radius (we nowadays call this ratio π). … | Previous minor planet ...

Archimedes is a large lunar impact crater on the eastern edges of the Mare Imbrium. To the south of the crater extends the Montes Archimedes mountainous region. On the southeastern rim is the Palus Putredinis flooded plain, containing a system of rilles named the Rimae Archimedes that extend over 150 kilometers. North-northwest of Archimedes stand the Montes Spitzbergen, a string of peaks in the Mare Imbrium. East of Archimedes is the Autolycus crater, and the stretch of lunar surface between these two formations was the crash-landing site of the Luna 2 landing craft. This was the first robotic craft to ...

The claw of Archimedes was a war machine 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 lift attacking ships partly out of the water, then either cause the ship to capsize or suddenly drop it. These machines featured prominently during the Second Punic War in 213 BC, when the Roman Republic attacked Syracuse with a ...

In most patent laws, unity of invention is a formal administrative requirement that must be met by a patent application in order to proceed to grant. Basically a patent application can relate only to one invention or a group of closely related inventions. The purpose of this provision is administrative, and in particular financial, i.e. it serves to limit the possibility to file one patent application for several inventions while paying only one set of fees (filing fee, search fee, examination fee, renewal fees and so on). Unity of invention ...

The so-called Age of Discovery was a period from the early 15th century and continuing into the early 17th century, during which European ships traveled around the world to search for new trading routes and partners to feed burgeoning capitalism in Europe. In the process, Europeans encountered peoples and mapped lands previously unknown to them. Among the most famous explorers of the period were Christopher Columbus, Vasco da Gama, Pedro Álvares Cabral, John Cabo ...

His claims to fame are varied. His contemporaries were most struck by his invention of a so-called land yacht, a carriage with sails, a little model of which was preserved at Scheveningen till 1802. The carriage itself had been lost long before; but we know that about the year 1600 Stevin, with Prince Maurice of Orange and twenty-six others, made use of it on the seashore between Scheveningen and Petten, that it was propelled solely by the force of the wind, and that it acquired a speed which exceeded that of horses. ...

Although a new or useful object or method may be developed to fulfill a specific purpose, the original idea may never be fully realised as a working invention, perhaps because the concept is in some way unrealistic or impractical. A "castle in the air" or a "pie in the sky" (or "castles in Spain") may refer to a creative idea which does not reach fruition due to practical considerations. The history of invention is full of such castles, as inventions are not necessarily invented in the order that is most useful. For example, the desig ...

The machines differed primarily in that the 400 series included more expansion slots (four instead of two) and a ST506 controller for an internal hard drive. Both models included the Arthur OS (later versions to be called RISC OS, see below), BBC BASIC and an emulator for Acorn's earlier BBC Micro, and were mounted in two-part cases with a small central unit, monitor on top, and a separate keyboard and three-button mouse.
