David Singmaster David Breyer Singmaster (born 1939, USA[1]) is a retired professor of mathematics at London London South Bank University, England, UK. A selfdescribed metagrobologist, he has a huge personal collection of mechanical puzzles and books of brain teasers. He is most famous for being an early adopter and enthusiastic promoter of the Rubik's Cube. His Notes on Rubik's "Magic Cube" which he began compiling in 1979 provided the first mathematical analysis of the Cube as well as providing one of the first published solutions. The book contained his cube notation which allowed the recording of Rubik's Cube Rubik's Cube moves, and which quickly became the standard. He is both a puzzle historian and a composer of puzzles, and many of his puzzles have been published in newspapers and magazines [...More...]  "David Singmaster" on: Wikipedia Yahoo

M. C. Escher Maurits Cornelis Escher (Dutch pronunciation: [ˈmʌurɪts kɔrˈneːlɪs ˈɛsxər]; 17 June 1898 – 27 March 1972), or commonly M. C. Escher, was a Dutch graphic artist who made mathematically inspired woodcuts, lithographs, and mezzotints. His work features mathematical objects and operations including impossible objects, explorations of infinity, reflection, symmetry, perspective, truncated and stellated polyhedra, hyperbolic geometry, and tessellations. Although Escher believed he had no mathematical ability, he interacted with the mathematicians George Pólya, Roger Penrose, Harold Coxeter and crystallographer Friedrich Haag, and conducted his own research into tessellation. Early in his career, he drew inspiration from nature, making studies of insects, landscapes, and plants such as lichens, all of which he used as details in his artworks [...More...]  "M. C.

Group Theory In mathematics and abstract algebra, group theory studies the algebraic structures known as groups. The concept of a group is central to abstract algebra: other wellknown algebraic structures, such as rings, fields, and vector spaces, can all be seen as groups endowed with additional operations and axioms. Groups recur throughout mathematics, and the methods of group theory have influenced many parts of algebra. Linear algebraic groups and Lie groups are two branches of group theory that have experienced advances and have become subject areas in their own right. Various physical systems, such as crystals and the hydrogen atom, may be modelled by symmetry groups. Thus group theory and the closely related representation theory have many important applications in physics, chemistry, and materials science [...More...]  "Group Theory" on: Wikipedia Yahoo 

Cayley Graph In mathematics, a Cayley graph, also known as a Cayley colour graph, Cayley diagram, group diagram, or colour group[1] is a graph that encodes the abstract structure of a group. Its definition is suggested by Cayley's theorem (named after Arthur Cayley) and uses a specified, usually finite, set of generators for the group. It is a central tool in combinatorial and geometric group theory.Contents1 Definition 2 Examples 3 Characterization 4 Elementary properties 5 Schreier coset graph 6 Connection to group theory6.1 Geometric group theory7 History 8 Bethe lattice 9 See also 10 Notes 11 External linksDefinition[edit] Suppose that G displaystyle G is a group and S displaystyle S is a generating set [...More...]  "Cayley Graph" on: Wikipedia Yahoo 

Wreath Product In mathematics, the wreath product of group theory is a specialized product of two groups, based on a semidirect product. Wreath products are used in the classification of permutation groups and also provide a way of constructing interesting examples of groups. Given two groups A and H, there exist two variations of the wreath product: the unrestricted wreath product A Wr H (also written A≀H) and the restricted wreath product A wr H. Given a set Ω with an Haction there exists a generalisation of the wreath product which is denoted by A WrΩ H or A wrΩ H respectively. The notion generalizes to semigroups and is a central construction in the KrohnRhodes structure theory of finite semigroups.Contents1 Definition 2 Notation and conventions 3 Properties 4 Canonical actions of wreath products 5 Examples 6 References 7 External linksDefinition[edit] Let A and H be groups and Ω a set with H acting on it [...More...]  "Wreath Product" on: Wikipedia Yahoo 

Layer By Layer Layerbylayer (LbL) deposition is a thin film fabrication technique. The films are formed by depositing alternating layers of oppositely charged materials with wash steps in between. This can be accomplished by using various techniques such as immersion, spin, spray, electromagnetism, or fluidics.[1]Contents1 Development 2 Implementation 3 Applications 4 See also 5 ReferencesDevelopment[edit] The first implementation of this technique is attributed to J. J. Kirkland and R. K. Iler of DuPont, who carried it out using microparticles in 1966.[2] The method was later revitalized by the discovery of its applicability to a wide range of polyelectrolytes by Prof. Gero Decher Gero Decher at Johannes GutenbergUniversität Mainz.[3] Implementation[edit] A simple representation can be made by defining two oppositely charged polyions as + and , and defining the wash step as W [...More...]  "Layer By Layer" on: Wikipedia Yahoo
