# The Power of Domino

Domino is a small rectangular block of hard material used as a game or as a mathematical tool. It features a line down the middle to visually divide it into two squares. Each end is either blank or has a number of spots, called pips, that indicate its value. Most domino sets contain a single unique piece for each value, from six pips on each end down to none or blank. These pieces are stacked on top of each other to form a chain.

The power of a single domino is greater than many people realize. A University of Toronto physicist named Stephen Morris has shown that the effect can be multiplied, creating chains that can knock down objects about one-and-a-half times their size. In a video demonstration, he places a 13-domino chain on the ground, then picks up the first domino in the chain with tweezers and moves it to a spot where it is no longer touching any other dominoes. As the first domino is moved, it converts potential energy to kinetic energy, allowing it to push the next domino over. This continues for each domino in the chain, until all are knocked over.

A domino is a flat rectangular block of hard material used as a table game or as a mathematical tool. It has a line down the middle to visually divide the top and bottom into two squares. Each end is either completely blank or has a number of spots, which indicate its value. Most domino sets contain one unique piece for each value, from six ips on each end down to none or blank. They are stacked on top of each other to create a chain.

When a person plays domino, they place the first tile down on the table and then play a tile that matches the color or value of the previous tile. The chain grows as each player takes turns playing a domino on the table, positioning it so that it touches the end of the previous domino and forms a line that gradually increases in length. When a player finishes the chain, they claim victory by counting the total number of pips on all the dominoes in the chain.

There are many games that can be played with a domino set, including scoring and blocking games. A popular game is bergen, where players compete to empty their hand of dominoes before the opponent. Other popular games include Mexican train and chicken foot. Many of these games also help children learn to recognize numbers and math skills.
