The Wolfram Demonstrations Project contains thousands of free interactive visualizations, with new entries added daily.
This Demonstration shows how to calculate, for a simple theoretical chemical reaction with just two reactants: a A+b B?c A_aB+d AB_b, the excess and the limitant reactants. The stoichiometric coefficients c and d have been calculated by satisfying the m...

A hypotrochogon is the trace (roulette) of a point attached to a regular polygon rolling without slipping inside another regular polygon [1]. The hypotrochogon can be curtate if the tracing point is inside the rolling polygon, or prolate if it is outsid...

Can a tetrahedron be divided into similar tetrahedra of different sizes? The answer is not known, but a solution for triangles was found by Zak [1]. This triangle, shown further in [2], has edges that are all powers of ?=1.1509639252577..., a ro...
