# Wonder of the Day: Domino

Dominoes are small, black and white pieces that can be stacked on end to form long lines. When the first domino in a line is tipped over, it causes the next domino in line to tip over and so on. As the dominoes pile up, they can create intricate and beautiful patterns. They can also be used to play games, where the goal is to knock over all of them with a single move. The term domino is also used to describe a sequence of events that begins with one simple action and then results in much greater—and often catastrophic—consequences. This is sometimes referred to as the “domino effect.” Today’s Wonder of the Day was inspired by Juan who wanted to know more about this topic.

The individual dominoes are called “tiles” or “bones,” and they come in a variety of shapes, sizes, and colors. Many people enjoy arranging them in straight or curved rows and then gently flicking them to see what happens. The classic 28-piece set includes dominoes with numbers from zero to six on each end, but some sets include blank ends that allow seven possible faces (these are known as double-six dominoes).

In addition to playing games, the dominoes can be arranged in a pattern to illustrate mathematical functions. A common example is using a domino with four at one end and five at the other to make a nine, which is divisible by both three and five. This is often used in scoring dominoes played in British pubs and social clubs, where players score points for completing a chain of tiles with the sum of the end tiles divisible by five or three.

Another way of thinking about domino is to consider it as a tool to help us stay on top of our tasks and responsibilities. For example, if you want to become more productive at work, you may try setting goals for yourself, such as making your bed every morning or cleaning out the basement. You can then rank the tasks that are most important and prioritize them. Each day, you should focus on the task with the highest priority and complete it before moving onto the next. In this way, you can achieve your most important goals and be more productive at work.
