Schlafli, Ludwig (1814-1895) Schläfli, ludwig (18141895). A German mathematician whose worked centered ongeometry, arithmetic and the theory of functions. http://www.daviddarling.info/encyclopedia/S/Schlafli.html
Extractions: A German mathematician whose worked centered on geometry, arithmetic and the theory of functions. He made an important contribution to non-Euclidean geometry when he proposed that spherical three-dimensional space could be thought of as the surface of a hypersphere in Euclidean four-dimensional space. Schläfli started out as a schoolteacher and amateur mathematician. He was also was an expert linguist and spoke many languages, including Sanskrit. In 1843 he served as a translator for the great mathematicians Jakob Steiner , Karl Jacobi , and Peter Dirichlet during their visit to Rome and learned a great deal from them. Ten years later he became professor of mathematics at Bern. However, his true importance was only appreciated following the publication of his magnum opus Theory of Continuous Manifolds in 1901, several years after his death.

Polytopes ludwig schlafli, a Swiss, made his great advances in the study of higher spacein the middle of the 19th century. His work went largely unnoticed, http://home.inreach.com/rtowle/Polytopes/polytope.html
Extractions: Polytope is the general term of the sequence, point, segment, polygon, polyhedron, ... So we learn in H.S.M. Coxeter 's wonderful Regular Polytopes (Dover, 1973). When time permits, I may try to provide a systematic approach to higher space. Dimensional analogy is an important tool, when grappling the mysteries of hypercubes and their ilk. But let's start at the beginning, and to simplify matters, and also bring the focus to bear upon the most interesting ramifications of the subject, let us concern ourselves mostly with regular polytopes. You may wish to explore my links to some rather interesting and wonderful polyhedra and polytopes sites, at the bottom of this page. Check out an animated GIF (108K) of an unusual rhombic spirallohedron. Yes, we shall be speaking of the fourth dimension, and, well, the 17th dimension, or for that matter, the millionth dimension. We refer to Euclidean spaces, which are flat, not curved, although such a space may contain curved objects (like circles, spheres, or hyperspheres, which are not polytopes). We are free to adopt various schemes to coordinatize such a space, so that we can specify any point within the space; but let us rely upon Cartesian coordinates, in which a point in an n -space is defined by an n -tuplet of real numbers. These real numbers specify distances from the origins along
Polytopes: Shadows Of Hypercubes The discovery of the regular polytopes is rightly credited to one ludwig schlafli,a Swiss, about 1850. He considered the vectors to the vertices of regular http://home.inreach.com/rtowle/Polytopes/Chapter2/Polytopes2.html
Extractions: Although this section is intended primarily for those already familiar with the broad outlines of the theory of regular polytopes, let us recall a few salient points: In n-dimensional space, there are always the three primitive polytopes: the simplex, the cross polytope, and the hypercube. The simplex (generalization of the triangle and tetrahedron) is the simplest polytope (with n-dimensional content) which can be constructed in an n-space. An n-simplex is bounded by (n-1)-simplexes, and has an (n-1)-simplex for its vertex figure. Regular simplexes are self-dual. The cross polytope (generalization of the square and Platonic octahedron) is named after the "cross" or frame of mutually perpendicular Cartesian coordinate axes which can be constructed in an n-space. There are just n such axes, and points equidistant from the origin along each axis, in both directions, are the vertices of a cross polytope. Cross polytopes are bounded by regular (n-1)-simplexes and have for vertex figures (n-1)-cross polytopes. The dual of an n-dimensional cross polytope is an n-cube. Hypercubes (generalizations of the square and cube) are specially simple zonotopes. They are bounded by (n-1)-cubes and have for vertex figure an (n-1)-simplex. Taken as zonotopes, they are "determined" by a star of n mutually perpendicular equal vectors. Thst is, they are "hyper-solids of translation" along those n vectors, "traced out" by a series of orthogonal translations. The dual of an n-cube is an n-dimensional cross polytope. They close-pack to fill the n-space, and moreover, when of unit edge length, the hypercube is called a measure polytope, and provides the measure for the unit of n-dimensional content.
