The Acorn Archimedes is a family of personal computers designed by Acorn Computers Ltd in Cambridge, England and sold in the late-1980s to mid-1990s, their first general purpose home computer based on their own ARM architecture (then the CPU and architecture was known as Acorn RISC Machine, or ARM. The first Archimedes was launched in 1987.
ARM's RISC design – 32-bit CPU (26-bit addressing), running at 8MHz, was stated as running at 4.5+MIPS, which provided a significant upgrade from 8-bit home computers, such as Acorn's previous ones. A claim of 'Fastest' micro in the world and 18 MIPS, was also made during tests.
The models in the family either omitted the Acorn or Archimedes part of the name, with the first models named "BBC Archimedes", while the name, Acorn Archimedes, is commonly used to describe any of Acorn's contemporary designs based on the same architecture. While the computers are no longer sold, computers such as the Raspberry Pi, can still run its operating system, RISC OS (at least later versions) as they use ARM chips that are (mostly) compatible.
Other mathematical achievements include deriving an accurate approximation of pi, defining and investigating the spiral bearing his name, and creating a system using exponentiation for expressing very large numbers. He was also one of the first to apply mathematics to physical phenomena, founding hydrostatics and statics, including an explanation of the principle of the lever. He is credited with designing innovative machines, such as his screw pump, compound pulleys, and defensive war machines to protect his native Syracuse from invasion.
The diameter of Archimedes is the largest of any crater on the Mare Imbrium. The rim has a significant outer rampart brightened with ejecta and the upper portion of a terraced inner wall, but lacks the ray system associated with younger craters. A triangular promontory extends 30 kilometers from the southeast of the rim.
The interior of the crater lacks a central peak, and is flooded with lava. It is devoid of significant raised features, although there are a few tiny meteor craters near the rim. Scattered wisps of bright ray material lie across the floor, most likely deposited by the impact that created Autolycus.
Surroundings
To the south of Archimedes extends the Montes Archimedes, a mountainous region. On the southeastern rim is the Palus Putredinis, a lava-flooded plain containing a system of rilles named the Rimae Archimedes, which extends over 150 kilometers. North-northwest of Archimedes stand the Montes Spitzbergen, a string of peaks in the Mare Imbrium. East of Archimedes is the crater Autolycus. Northeast of Archimedes is the prominent crater Aristillus. The lava plain between Archimedes, Aristillus, and Autolycus forms the Sinus Lunicus bay of Mare Imbrium. A wrinkle ridge leads away from Archimedes toward the north-northwest, crossing this mare.
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. These forms are pretty 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.
Description
Archimedes is a genus of fenestrate bryozoans with a calcified skeleton of a delicate spiral-shaped mesh that was thickened near the axis into a massive corkscrew-shaped central structure. The most common remains are fragments of the mesh that are detached from the central structure, and these may not be identified other than by association with the "corkscrews", that are fairly common. Specimens in which the mesh remains attached to the central structure are rare. Like other bryozoans, Archimedes forms colonies, and like other fenestrates, the individuals (or zooids) lived on one side of the mesh, and can be recognized for the two rows of equally distanced rimmed pores. Inside the branches, neighbouring individuals were in contact through small canals. Bryozoans are stationary epifaunal suspension feeders.

Ancient Greeks (Archimedes) almost discovered calculus! | DIw/oI #4
Newton or Leibniz? This never-ending debate on who discovered calculus would be settled if ancient Greeks were not so afraid of the concept of infinitesimals. Archimedes' work calculates the area (called quadrature back then) enclosed by a parabola and a line (i.e. parabolic segment), which is typically solved by calculus today. He had also developed the modern idea of limits, just not in modern notations, so ancient Greeks are really only a few steps away from discovering calculus!

Understanding Archimedes' principle
The great Greek scientist Archimedes’ “eureka” moment is quite popular. Why did Archimedes get so excited about his thought experiment? What was the concept he deduced while he was taking a bath? More importantly, did Archimedes solve his king’s crown problem using an immersing experiment or a float balance?

Archimedes Principle: Explained in Really Simple Words
Archimedes principle states that if an object is submerged in a fluid, then the buoyant force acting on it is equal to the weight of the fluid displaced by that object. Buoyant force exists because pressure increases as an object goes deeper in a fluid, which, in this case, is water. Due to this, the force from the pressure exerted in the downward direction on the top of the object is LESS than the force from pressure exerted in the upward direction on the bottom of the object.
When Archmiedes got into the bathtub, he realized that as more of his body was submerged in water, the more water spilled over the bathtub’s edge. He realized that there must be a clear relationship between his weight and the weight of the water displaced by his submerged body. This was a groundbreaking idea, and o...
This physics / fluid mechanics video tutorial provides a basic introduction into archimedes principle and buoyancy. It explains how to calculate the upward buoyant force acting on an object and it shows how to derive the buoyant force formula. It discusses how to use free body diagrams to calculate the tension force in a rope supporting a block in the fluid using the buoyancy force and the weight force of the block.

The Acorn Archimedes is a family of personal computers designed by Acorn Computers Ltd in Cambridge, England and sold in the late-1980s to mid-1990s, their first general purpose home computer based on their own ARM architecture (then the CPU and architecture was known as Acorn RISC Machine, or ARM. The first Archimedes was launched in 1987.
ARM's RISC design – 32-bit CPU (26-bit addressing), running at 8MHz, was stated as running at 4.5+MIPS, which provided a significant upgrade from 8-bit home computers, such as Acorn's previous ones. A claim of 'Fastest' micro in the world and 18 MIPS, was also made during tests.
The models in the family either omitted the Acorn or Archimedes part of the name, with the first models named "BBC Archimedes", while the name, Acorn Archimedes, is commonly used to describe any of Acorn's contemporary designs based on the same architecture. While the computers are no longer sold, computers such as the Raspberry Pi, can still run its operating system, RISC OS (at least later versions) as they use ARM chips that are (mostly) compatible.
