Document Locator | MathJax
The purpose of MathJax is to bring the ability to include mathematics easily in web pages to as wide a range of browsers as possible. Authors can specify mathematics in a variety of formats (e.g., MathML , LaTeX , or AsciiMath ), and MathJax provides high-quality mathematical typesetting even in those browsers that do not have native MathML support. This all happens without the need for special downloads or plugins, but rendering will be enhanced if high-quality math fonts (e.g., STIX ) are available to the browser. MathJax is broken into several different kinds of components: page preprocessors, input processors, output processors, and the MathJax Hub that organizes and connects the others. The input and output processors are called jax , and are described in more detail below.Math Monday – The Museum of Mathematics
Math Monday In a partnership between the Museum and Make: Online , George Hart writes a weekly column discussing fun, experiential, and puzzling topics in mathematics. Collected here are the Math Monday posts from past weeks. These articles each first appeared on Make: Online .
(New) There is now a forum installed for sharing comments, questions and suggestions about anything on this site! There are discussion boards devoted to: (New) My free software application, Plans Unfolding , has been released after much development and testing.

Octave
GNU Octave is a high-level interpreted language, primarily intended for numerical computations. It provides capabilities for the numerical solution of linear and nonlinear problems, and for performing other numerical experiments. It also provides extensive graphics capabilities for data visualization and manipulation.
Acme Klein Bottle
At last, Acme has conquered topological and engineering frontiers to manufacture genuine glass Klein Bottles. These are the finest closed, non-orientable, boundary-free manifolds sold anywhere in our three spatial dimensions. These elegant bottles make splendid gifts, outstanding classroom displays, and inferior mouse-traps. With its circle of singularities, an Acme Klein Bottle can be said to exist inside of itself -- especially handy during time-reversals.An L-system or Lindenmayer system is a parallel rewriting system , namely a variant of a formal grammar , most famously used to model the growth processes of plant development , but also able to model the morphology of a variety of organisms. [ 1 ] A L-system consists of an alphabet of symbols that can be used to make strings , a collection of production rules which expand each symbol into some larger string of symbols, an initial " axiom " string from which to begin construction, and a mechanism for translating the generated strings into geometric structures. L-systems can also be used to generate self-similar fractals such as iterated function systems . L-systems were introduced and developed in 1968 by the Hungarian theoretical biologist and botanist from the University of Utrecht , Aristid Lindenmayer (1925–1989).
