Differential Geometry

A version of the classic worm game, played in non-Euclidean space - that is to say, on the surface of various three-dimensional shapes. It features retro-style vector graphics, exciting differential geometry and almost guaranteed nausea!

smib is a mosaic of FORTH and LISP, C Sauce and an experimental programming language close to mathematical language. In this version : law of large numbers, central limit theorem, hyperbolic trigonometry, warnings are cleaned . Features . Number theory : infinite size integers, arithmetic...

Custom Geometry is an extension which resizes and positions the window according to your settings. Custom Geometry adds a button to the Firefox status bar that will resize the Firefox window to your specifications. Many other extensions will resize the window, but only to preset dimensions,...

This function solves the linear fractional-order differential equations (FODE) with constant coefficients. The short memory principle has not neen used here, so the length of input signal is limited to few hundred samples. The parameters of the FODE (in its standard form) are the inputs of this...

The EJS Differential Galactic Rotation Model illustrates the model of galactic rotation proposed by Jan Oort in 1927. In Oort's model most of the mass of the galaxy is concentrated at the center. Stars move in circular orbits around the center, with orbital speeds that are inversely proportional...
