#### How Dominos Are Used to Explain the Physics of Energy Conversion

Dominos are a game of laying out a series of rectangular tiles, whose ends are either blank or have a number of spots — pips — on them. They can be played as a traditional positional game or as a solitaire variant. A domino set typically contains one tile for each possible combination of spots, from six pips down to none or blank.

They are often made of bone, silver lip ocean pearl oyster shell (MOP), ivory or a dark hardwood such as ebony, with contrasting black or white pips inlaid or painted. They are typically twice as long as they are wide, which makes it easier to stack them.

Originally, they represented the 21 possible faces of two six-sided dice. During the mid-18th century, Western dominoes became popular and were later brought to China. Chinese dominoes differ from European ones in that they have a line down the middle, instead of the pips, to divide them visually into two squares.

A domino effect is the cumulative effect produced when a single event sets off a chain of similar events. It is usually used to describe a mechanical effect but can also be applied to a non-mechanical scenario.

In a broader sense, dominoes can be used to illustrate the physics of energy conversion. When a domino falls, much of its potential energy converts into kinetic energy, which is transferred to the next domino.

Some of that energy can also be converted to heat, which is then transferred to the other dominoes in the chain. This heat can cause them to swell or contract, and sometimes even break.

Lily Hevesh, a domino artist, uses this process to create mind-blowing setups for her YouTube channel, Hevesh5, which has over 2 million subscribers.

Her designs can be as simple or elaborate as she wants, using straight lines, curved lines, grids that form pictures when they fall, stacked walls and 3D structures like towers and pyramids.

She starts by considering the theme of the installation she’s designing, then brainstorming images or words she might want to use in the design.

Once she’s got a clear idea of what she wants, she creates the actual art. She uses a variety of different tools – including a drill press, radial arm saw, scroll saw and belt sander – to cut the pieces she needs to make her designs.

Then she uses a combination of her own muscle memory and her knowledge of engineering-design principles to lay out the art. This involves creating a design that is as big or small as she wants, then sketching out the layout with arrows to show how the dominoes should fall.

When she’s done, she sticks it all together with tape and glue – making sure she has a strong enough bond to hold the dominoes in place. She then takes her artwork outside to hang it up and admire it for a while.

As you play with dominoes, you will start to build new habits that will carry over to other parts of your life, transforming them into “dominoes of your own.” Once you’ve made a commitment to a behavior or a change in how you think about yourself, the dominoes will continue to fall one by one, forming a cascade of new habits and changing your identity.

#### The Basics of Poker

Poker is a card game where players bet money on the outcome of their hand. There are countless variants of poker, but most of them follow some basic rules.

Generally, each player is dealt five cards and must use them to make the best possible hand. In many variations of the game, a player can replace any one card with another, in effect adding to their hand. In most games, this is called a “bluff.”

The highest-ranking poker hand is the royal flush, consisting of a 10, Jack, Queen, King and Ace of the same suit (all clubs, diamonds, hearts or spades). A royal straight flush is made from the same five-card hand but is not as strong.

Other hands include a high pair, which is two distinct pairs and a 5th card; a flush, which is made up of 5 consecutive cards from the same suit; and a straight, which is made up of 4 of a kind and a fifth card of any rank. These hands can be broken ties by the high card, which is any card that does not qualify as a straight or a flush but which is still higher than the highest-ranking hand.

To play poker, you should learn how to read the cards. You can do this by practicing with friends or by watching experienced players. This will help you develop your instincts quickly.

Before the cards are dealt, each player is required to contribute an amount called the ante. This amount is usually based on the size of the pot and is typically the minimum bet for a game.

The antes may be raised or lowered during the betting rounds, depending on the game rules. In no-limit games, a player can raise an ante as much as he wants, while in pot-limit games a player cannot raise an ante more than he put into the pot.

When a player raises, he must put in the amount of the original ante plus an additional amount, which is called the “raise”. If he fails to meet his raise, the pot is returned to the person who opened the bet.

Alternatively, he can fold (put all of his chips in the pot and withdraw from the game). This is also known as the “call” position.

If a player is the last one to bet, they are called the “blind.” This person must place a small amount of money in the pot before the cards are dealt. The blinds are usually paid by the dealer and pass clockwise around the table, except in three-blind games, where they go on “the button” instead of being paid by the dealer.

A player can bluff by opening the pot with a large bet and hoping that other players will call, but it is more common to win by folding than by bluffing. This is because players who bluff rarely have the strongest hands.

The main objective of a poker game is to win the pot. The pot is the aggregate of all bets placed during the hand. The player with the highest-ranking hand wins the pot, or, if no player has a superior hand, the pot is shared among all players who are in contention for the hand.
