stood on end, and toppling the first domino. That domino topples the one next to it, and so on. In theory, however long the chain the dominoes will still fall. This is because the energy required to topple each domino is less than the energy transferred by each impact, so the chain is self-sustaining. Energy is stored by setting domino in the metastable

upright position, and that energy is what keeps the chain toppling. The mechanics of domino toppling is described by W. J. Stronge as a system with two attractor

A chain reaction is a sequence of reactions where a reactive product or by-product causes additional reactions to take place. In a chain reaction, positive feedback leads to a self-amplifying chain of events....

Dominoes

Dominoes generally refers to the collective gaming pieces making up a domino set or to the subcategory of tile games played with domino pieces. In the area of mathematical tilings and polyominoes, the word domino often refers to any rectangle formed from joining two congruent squares edge to edge...
