Klein Bikes
Klein was a bicycle company founded by Gary Klein that pioneered the use of large diameter aluminium alloy tubes for greater stiffness and lower weight. Klein produced his first bicycle frames while a student at the Massachusetts Institute of Technology during the 1970s, and full production runs of frames began in the 1980s. In 1995 the company was purchased by the Trek Bicycle Corporation, and the original Klein factory at Chehalis, Washington, closed in 2002 as production moved to the Trek headquarters at Waterloo, Wisconsin. Widespread distribution in the United States stopped in 2007, and ceased altogether in the rest of the world in 2009. History Gary Klein, born , attended the University of California, Davis, University of California at Davis before transferring to the Massachusetts Institute of Technology (MIT). During the Traditions and student activities at MIT#Independent Activities Period, Independent Activities Period in 1973, a group of students including Klein w ...

Yves Klein
Yves Klein (; 28 April 1928 – 6 June 1962) was a French artist and an important figure in post-war European art. He was a leading member of the French artistic movement of Nouveau réalisme founded in 1960 by art critic Pierre Restany. Klein was a pioneer in the development of performance art, and is seen as an inspiration to and as a forerunner of Minimalism, minimal art, as well as pop art. He developed and used International Klein Blue. Biography Klein was born in Nice, in the Alpes-Maritimes department of France. His parents, Fred Klein and Marie Raymond, were both painters. His father painted in a loose Post-Impressionism, post-impressionist style, while his mother was a leading figure in Art informel, and held regular soirées with other leading practitioners of this Parisian abstract movement. Klein received no formal training in art, but his parents exposed him to different styles. His father was a figurative style painter, while his mother had an interest in abstract ex ...

Klein Bottle
In mathematics, the Klein bottle () is an example of a Orientability, non-orientable Surface (topology), surface; that is, informally, a one-sided surface which, if traveled upon, could be followed back to the point of origin while flipping the traveler upside down. More formally, the Klein bottle is a two-dimensional manifold on which one cannot define a normal vector at each point that varies continuous function, continuously over the whole manifold. Other related non-orientable surfaces include the Möbius strip and the real projective plane. While a Möbius strip is a surface with a Boundary (topology), boundary, a Klein bottle has no boundary. For comparison, a sphere is an orientable surface with no boundary. The Klein bottle was first described in 1882 by the mathematician Felix Klein. Construction The following square is a fundamental polygon of the Klein bottle. The idea is to 'glue' together the corresponding red and blue edges with the arrows matching, as in the diagr ...

Klein Tools
Klein Tools, Inc. is an American company based in Lincolnshire, IL that manufactures hand tools. The company is known for its popularity with workers in the electrical and telecommunications industries. Lineman's pliers in the past were often called "Kleins," an example of a genericized trademark. Klein's line-up contains more than 5,000 different tools, including 165 different types of pliers, in addition to screwdrivers, nut drivers, wire pulling and stripping tools, crimping tools, scissors, snips and shears, cable and bolt cutters, multimeters, electrical outlet testers, conduit benders, personal protective equipment, and tool bags. Klein produces a high-end line of tools under its Journeyman label. History Klein Tools was founded in 1857 in Chicago, Illinois by German immigrant Mathias Klein. The first tool Klein made was a pair of side-cutting pliers for a telegraph lineman. The company grew as the telegraph and eventually telephone and electrical industries g ...

Klein, Texas
Klein is an unincorporated community in Harris County, Texas, United States, roughly bordering Texas State Highway 99 to the north, Texas State Highway 249 to the west, Interstate 45 to the east, and the city of Houston to the south. It includes the entire area of Klein ISD. Residents of the zip codes 77066, 77069, 77086, 77379, 77388, 77389 and 77391 can use Klein as their postal city. Klein is one of the most diverse, as well as being one of the largest unincorporated areas of Houston. It is named after Adam Klein, a German immigrant whose best-known great-great-grandson is singer Lyle Lovett. Other famous sons and daughters of the Klein community include actor Jim Parsons, actor Lee Pace, actor Matthew Bomer, actress Lynn Collins, actress Sherry Stringfield, singer/songwriter Derek Webb, actor Ben Rappaport, Major League Baseball players David Murphy and Josh Barfield, NFL players Randy Bullock, Ashton Youboty, Mike Green, and Olympic gold medalists Laura Wilkinson, ...

Klein Surface
In mathematics, a Klein surface is a dianalytic manifold of complex dimension 1. Klein surfaces may have a boundary and need not be orientable. Klein surfaces generalize Riemann surfaces. While the latter are used to study algebraic curves over the complex numbers analytically, the former are used to study algebraic curves over the real numbers analytically. Klein surfaces were introduced by Felix Klein in 1882. A Klein surface is a surface (i.e., a differentiable manifold of real dimension 2) on which the notion of angle between two tangent vectors at a given point is well-defined, and so is the angle between two intersecting curves on the surface. These angles are in the range ,π since the surface carries no notion of orientation, it is not possible to distinguish between the angles α and −α. (By contrast, on Riemann surfaces are oriented and angles in the range of (-π,π] can be meaningfully defined.) The length of curves, the area of submanifolds and the notion ...

Klein Graphs
In the mathematical field of graph theory, the Klein graphs are two different but related regular graphs, each with 84 edges. Each can be embedded in the orientable surface of genus 3, in which they form dual graphs. The cubic Klein graph This is a 3- regular (cubic) graph with 56 vertices and 84 edges, named after Felix Klein. It is Hamiltonian, has chromatic number 3, chromatic index 3, radius 6, diameter 6 and girth 7. It is also a 3- vertex-connected and a 3- edge-connected graph. It has book thickness 3 and queue number 2. It can be embedded in the genus-3 orientable surface (which can be represented as the Klein quartic), where it forms the Klein map with 24 heptagonal faces, Schläfli symbol 8. According to the ''Foster census'', the Klein graph, referenced as F056B, is the only cubic symmetric graph on 56 vertices which is not bipartite. It can be derived from the 28-vertex Coxeter graph. Algebraic properties The automorphism group of the Klein graph is the g ...
