# How Dominoes Are Used in Art and Science

Dominoes are a fascinating toy, not just for children but also for adults. They’re a great way to practice counting, spelling, and math skills. They can also be used to make beautiful designs and structures. In addition, there are many games that can be played with dominoes. The most basic game involves two players and requires a double-six set. The 28 tiles are shuffled and then arranged so that each player draws seven of them. The rest are not used. Each player then alternately extends the line of play with one tile. The first player to reach a specified total wins the game.

Unlike playing cards, the faces of dominoes do not display suits or numbers. Instead, each domino has an identity-bearing side that is either identically patterned or blank (indicated in the listing below by a zero). The other face is marked with an arrangement of dots resembling those on a die.

The first domino that falls initiates a chain reaction, causing the others to fall in succession. This is an analogy to how a nerve impulse travels along the axon of a cell. It can only be triggered once, but once it’s initiated the effect spreads at a steady pace without loss of energy.

A similar analogy is the Domino Theory, which states that the rise or fall of communist influence in a country will have a knock-on effect in neighboring countries. In fact, the theory has been used to justify interventionist policies in other parts of the world.

Before Hevesh knocks over a single domino, she builds test versions and films them in slow motion to see what will happen. This allows her to correct mistakes early on, before the dominoes are put together in a 3-D setting.

She focuses on the biggest, 3-D sections first, and then adds flat arrangements and finally lines of dominoes connecting all the sections. Once she’s happy with how a particular section works, she moves on to the next section.

The final step is to test the whole installation before the big show. Hevesh carefully checks that every domino is positioned just right. Once she’s satisfied, she then sets the whole thing in motion.

When children are learning to count, they can use a large set of dominoes to affix to a whiteboard and practice adding them together. They can also choose a domino from a stack and name the number of dots on it. For example, a student might choose a domino with 2 and 4 dots on it, and the class can call out “2+4=6.” Students may also work on their own by choosing a domino from a stack or bag at random, drawing its dot pattern, and writing the related equation.
