Soma Cube
The Soma cube is a solid dissection puzzle invented by Danish polymath Piet Hein in 1933 during a lecture on quantum mechanics conducted by Werner Heisenberg. Seven pieces made out of unit cubes must be assembled into a 3×3×3 cube. The pieces can also be used to make a variety of other 3D shapes. The pieces of the Soma cube consist of all possible combinations of three or four unit cubes, joined at their faces, such that at least one inside corner is formed. There is one combination of three cubes that satisfies this condition, and six combinations of four cubes that satisfy this condition, of which two are mirror images of each other (see Chirality). Thus, 3 + (6 × 4) is 27, which is exactly the number of cells in a 3×3×3 cube. The Soma cube was popularized by Martin Gardner in the September 1958 Mathematical Games column in ''Scientific American.'' The book '' Winning Ways for your Mathematical Plays'' also contains a detailed analysis of the Soma cube problem. Ther ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Michael Guy
Michael J. T. Guy (born 1 April 1943) is a British computer scientist and mathematician. He is known for early work on computer systems, such as the Phoenix system at the University of Cambridge, and for contributions to number theory, computer algebra, and the theory of polyhedra in higher dimensions. He worked closely with John Horton Conway, and is the son of Conway's collaborator Richard K. Guy. Mathematical work With Conway, Guy found the complete solution to the Soma cube of Piet Hein. Also with Conway, an enumeration led to the discovery of the grand antiprism, an unusual uniform polychoron in four dimensions. The two had met at Gonville and Caius College, Cambridge, where Guy was an undergraduate student from 1960, and Conway was a graduate student. It was through Michael that Conway met Richard Guy, who would become a co-author of works in combinatorial game theory. Michael Guy with Conway made numerous particular contributions to geometry, number and game theory ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Parker Brothers
Parker Brothers (known by Parker outside of North America) was an American toy and game manufacturer which in 1991 became a brand of Hasbro. More than 1,800 games were published under the Parker Brothers name since 1883. Among its products were ''Monopoly (game), Monopoly'', Cluedo, Clue (licensed from the British publisher and known as ''Cluedo'' outside of North America), ''Sorry! (game), Sorry!'', ''Risk (game), Risk'', ''Trivial Pursuit'', ''Ouija'', ''Aggravation (board game), Aggravation'', ''Bop It'', ''Scrabble'' (under a joint partnership with Milton Bradley Company, Milton Bradley in North America and Canada), and ''Probe (parlor game), Probe''. The trade name became defunct with former products being marketed under the "Hasbro Gaming" label with the logo shown on Monopoly (game), Monopoly games. History Parker Brothers was founded by George Swinnerton Parker, George S. Parker. Parker's philosophy deviated from the prevalent theme of board game design; he believed th ...

Rosewood
Rosewood refers to any of a number of richly hued timbers, often brownish with darker veining, but found in many different hues. True rosewoods All genuine rosewoods belong to the genus ''Dalbergia''. The pre-eminent rosewood appreciated in the Western world is the wood of ''Dalbergia nigra''. It is best known as "Brazilian rosewood", but also as "Bahia rosewood". This wood has a strong, sweet smell, which persists for many years, explaining the name ''rosewood''. Another classic rosewood comes from ''Dalbergia latifolia'', known as (East) Indian rosewood or ''sonokeling'' (Indonesia). It is native to India and is also grown in plantations elsewhere in Pakistan (Chiniot). Madagascar rosewood (''Dalbergia maritima''), known as ''bois de rose'', is highly prized for its red color. It is overexploited in the wild, despite a 2010 moratorium on trade and illegal logging, which continues on a large scale. Throughout southeast Asia, ''Dalbergia oliveri'' is harvested for use in ...

Piet Hein (Denmark)
Piet Hein (16 December 1905 – 17 April 1996) was a Danish polymath (mathematician, inventor, designer, writer and poet), often writing under the Old Norse pseudonym Kumbel, meaning " tombstone". His short poems, known as '' gruks'' or grooks ( da, gruk), first started to appear in the daily newspaper ''Politiken'' shortly after the German occupation of Denmark in April 1940 under the pseudonym "Kumbel Kumbell". He also invented the Soma cube and the board game Hex. Biography Hein, a direct descendant of Piet Pieterszoon Hein, the 17th century Dutch naval hero, was born in Copenhagen, Denmark. He studied at the Institute for Theoretical Physics (later to become the Niels Bohr Institute) of the University of Copenhagen, and Technical University of Denmark. Yale awarded him an honorary doctorate in 1972. He died in his home on Funen, Denmark in 1996. Resistance Piet Hein, who, in his own words, "played mental ping-pong" with Niels Bohr in the inter-War period, found himself con ...
