Steiner Brothers
The Steiner Brothers are an American professional wrestling tag team consisting of brothers Rick Steiner (real name Robert Rechsteiner) and Scott Steiner (real name Scott Rechsteiner). The brothers wrestled as amateurs at the University of Michigan. The team made their professional wrestling debut in 1989, and competed in promotions such as Extreme Championship Wrestling (ECW), New Japan Pro-Wrestling (NJPW), World Championship Wrestling (WCW), and the World Wrestling Federation (WWF), winning 11 world tag team championships and one United States Tag Team Championship, before disbanding in 1998. The brothers reunited on the independent circuit in the early 2000s, and Total Nonstop Action Wrestling in May 2007. They are the first tag team to hold the WWF World Tag Team Championship, the WCW World Tag Team Championship, and the IWGP Tag Team Championship. The Steiner Brothers are highly regarded, considered as one of the greatest tag teams in professional wrestling history. On Apr ...

Steiner Brothers (tap-dancing Trio)
The Steiner Brothers were a Canadian tap-dancing trio active in North American nightclubs and theatres and in television and film during the 1950s and 1960s. The group consisted of three brothers from Winnipeg: Roy Steiner (May 20, 1941 – October 27, 2019), Ron Steiner (born 1942), and Rob Steiner (born 1944). The group also sang and performed comedy. Ron Steiner was also one of the original Mouseketeers for Walt Disney. Family background and education The Steiner Brothers are the children of Ralph Steiner and Madge Steiner (née Hoffard). Their father was a child prodigy on the violin who had conducted the Winnipeg Symphony Orchestra at the age of 12, and later worked as the bandmaster of his own dance band. Their mother had danced professionally with the Hoffard Sisters, a Saskatchewan-based dance troupe in the 1930s and 1940s. The couple performed together until they had children, with their father sometimes assuming the persona of Howie Squeeks, a clown. The family resided i ...

Steiner, Michigan
Steiner was a small farming settlement in what is now Frenchtown Charter Township, Monroe County in the U.S. state of Michigan. The village no longer exists but some structures remain and are in use. It was situated at the intersection of Steiner Road and Laduke Road near the current CSX Railroad crossing. The village of Steiner was located about five miles north of Monroe, and was centered around the Steiner Depot of the Pere Marquette Railroad. Steiner was founded by and named for William Steiner in 1873. At one time the town had a railroad depot, creamery, granary, freight scales, a sawmill, basket factory, pottery and brick works, a saloon (the Steiner Inn), the Laduke general store A general merchant store (also known as general merchandise store, general dealer, village shop, or country store) is a rural or small-town store that carries a general line of merchandise.

Steiner's Theorem
The parallel axis theorem, also known as Huygens–Steiner theorem, or just as Steiner's theorem, named after Christiaan Huygens and Jakob Steiner, can be used to determine the moment of inertia or the second moment of area of a rigid body about any axis, given the body's moment of inertia about a parallel axis through the object's center of gravity and the perpendicular distance between the axes. Mass moment of inertia Suppose a body of mass is rotated about an axis passing through the body's center of mass. The body has a moment of inertia with respect to this axis. The parallel axis theorem states that if the body is made to rotate instead about a new axis , which is parallel to the first axis and displaced from it by a distance , then the moment of inertia with respect to the new axis is related to by : I = I_\mathrm + md^2. Explicitly, is the perpendicular distance between the axes and . The parallel axis theorem can be applied with the stretch rule and perpend ...

Steiner Tree
In combinatorial mathematics, the Steiner tree problem, or minimum Steiner tree problem, named after Jakob Steiner, is an umbrella term for a class of problems in combinatorial optimization. While Steiner tree problems may be formulated in a number of settings, they all require an optimal interconnect for a given set of objects and a predefined objective function. One well-known variant, which is often used synonymously with the term Steiner tree problem, is the Steiner tree problem in graphs. Given an undirected graph with non-negative edge weights and a subset of vertices, usually referred to as terminals, the Steiner tree problem in graphs requires a tree of minimum weight that contains all terminals (but may include additional vertices) and minimizes the total weight of its edges. Further well-known variants are the ''Euclidean Steiner tree problem'' and the '' rectilinear minimum Steiner tree problem''. The Steiner tree problem in graphs can be seen as a generalization o ...

Poncelet–Steiner Theorem
In the branch of mathematics known as Euclidean geometry, the Poncelet–Steiner theorem is one of several results concerning compass and straightedge constructions having additional restrictions imposed on the traditional rules. This result, related to the rusty compass equivalence and to Steiner constructions, states that whatever can be constructed by straightedge and compass (drafting), compass together can be constructed by straightedge alone, provided that a single circle and its centre_(geometry), centre are given: : ''Any Euclidean construction, insofar as the given and required elements are points (or lines), if it can be completed with both the compass and the straightedge together, may be completed with the straightedge alone provided that no fewer than one circle with its center exist in the plane.'' Though a compass can make constructions significantly easier, it is implied that there is no functional purpose of the compass once the first circle has been drawn; the co ...

Steiner Surface
In mathematics, the Roman surface or Steiner surface is a self-intersecting mapping of the real projective plane into three-dimensional space, with an unusually high degree of symmetry. This mapping is not an immersion of the projective plane; however, the figure resulting from removing six singular points is one. Its name arises because it was discovered by Jakob Steiner when he was in Rome in 1844. The simplest construction is as the image of a sphere centered at the origin under the map f(x,y,z)=(yz,xz,xy). This gives an implicit formula of : x^2 y^2 + y^2 z^2 + z^2 x^2 - r^2 x y z = 0. \, Also, taking a parametrization of the sphere in terms of longitude () and latitude (), gives parametric equations for the Roman surface as follows: :x=r^ \cos \theta \cos \varphi \sin \varphi :y=r^ \sin \theta \cos \varphi \sin \varphi :z=r^ \cos \theta \sin \theta \cos^ \varphi The origin is a triple point, and each of the -, -, and -planes are tangential to the surface there. The ot ...

Steiner System
250px, thumbnail, The Fano plane is a Steiner triple system S(2,3,7). The blocks are the 7 lines, each containing 3 points. Every pair of points belongs to a unique line. In combinatorial mathematics, a Steiner system (named after Jakob Steiner) is a type of block design, specifically a t-design with λ = 1 and ''t'' = 2 or (recently) ''t'' ≥ 2. A Steiner system with parameters ''t'', ''k'', ''n'', written S(''t'',''k'',''n''), is an ''n''-element set ''S'' together with a set of ''k''-element subsets of ''S'' (called blocks) with the property that each ''t''-element subset of ''S'' is contained in exactly one block. In an alternative notation for block designs, an S(''t'',''k'',''n'') would be a ''t''-(''n'',''k'',1) design. This definition is relatively new. The classical definition of Steiner systems also required that ''k'' = ''t'' + 1. An S(2,3,''n'') was (and still is) called a ''Steiner triple'' (or ''triad'') ''system'', while an S(3,4,''n'') is called a ''Steiner ...

Steiner House
Steiner House is a building in Vienna, Austria. It is considered one of the major works of architect Adolf Loos. Background Loos was still starting his career in 1910 when he designed and constructed the Steiner house in Vienna, Austria. This design was much better accepted than Loos' earlier works and quickly became a worldwide example of rationalist architecture. In his buildings, Loos normally starts with one main volume in which the space, configuration, and elements follows the rules and composition of classical architecture. He organizes the interior of that volume with smaller cubes, rectangles boxes, and cylinders arranged in a volumetric puzzle of sorts. This determines the internal organization of his buildings and Loos regularly uses protrusions from the main block to create other areas of the building such as terraces. In the Steiner house, Loos uses his volumes to create a classical tripartite façade. He does this by creating a recess between the two wings of th ...
