Olympic curling has taken to the ice, but if you're like most Americans, this writer included, the game is a bit baffling. Here's a quick, stripped-down primer on everyone's favorite icy alternative to shuffleboard. It doesn't cover anywhere near all of the game's nuances, but it should give you enough info that you can enjoy watching an end or two. (And yes, you'll learn what an "end" is.)

WHAT'S THE OBJECT OF CURLING?

Good question. First, let's get a bit of the jargon down. The playing surface in curling is called "the sheet." Sheet dimensions can vary, but they're usually around 150 feet long by about 15 feet wide. The sheet is covered with tiny droplets of water that become ice and cause the stones to "curl," or deviate from a straight path. These water droplets are known as "pebble."

At each end there's a target that looks like a big bullseye. These targets are known as "the houses." The center of the house is known as the "button." Basically, the object of the game is to get your stones closer to the button than the other team gets theirs.

WHAT'S WITH THE SWEEPING?

Remember how we talked about the pebble of ice droplets that the rock has to travel across? When the stone touches the pebble, there's friction, which can slow down the stone and makes it curl away from its straight path to the house.

Obviously, that friction is not always a good thing, but sweeping helps combat the problem. The sweeping motion raises the temperature of the ice by a degree or two, which diminishes the friction between the pebble and the stone and keeps the stone moving in a straight line.

WHAT ABOUT ALL THE YELLING?

Each curling team has four members: a lead, a second, a vice-skip (or third), and a skip. Each "end" (curling's equivalent of a baseball inning) involves both teams shooting (or "delivering") eight stones at the house, with players delivering two stones apiece.

When the lead, second, and vice are delivering their stones, the skip stands at the opposite end of the sheet (near the house) and uses his broom to give his teammates a target for their deliveries. Once the stone has been delivered and is a "running stone" (that is, one that's still sliding), the skip then yells to the sweepers to let them know when to sweep and how hard. When the skip shoots the last two stones of a team's end, the vice takes over calling the shots.

HOW DO YOU KEEP SCORE?

In each end, both teams send eight stones down the sheet. Once all 16 stones have been delivered, the team with the stone that's closest to the button (center of the house) effectively "wins" the end. Only this team will earn any points for the end. It gets a point for each of its stones that are in the house and closer to the button than the other team's closest stone. Since the team that won the end always has at least one stone that's closer to the button than their opponent, the team always scores at least one point, and could score up to eight points.

If neither team manages to keep a stone in the house during an end, it's known as a "blank end," and no points are scored. Olympic curling matches last for 10 ends unless there is a tie, in which case it goes to extra-ends, curling's equivalent of overtime.

WHAT'S THE HAMMER?

As you might have guessed from reading about the scoring system, throwing the last stone of an end is a huge advantage. If you've got the last stone, you can always try to knock the other team's best stone away from the button. If a team holds the last stone for an end, it "has the hammer," and should probably be able to score some points. If the team without the hammer manages to somehow stymie their opponent and score points, it's called a "stolen end." Whichever team fails to score points in an end gets the hammer for the next end.

SO IS THERE STRATEGY INVOLVED?

Yes, there's all sorts of strategy in curling. Let's say your team doesn't have the hammer. You're at a huge disadvantage when it comes to scoring points, so you might opt to play defensively. To do that, you might just deliver a number of "guards," or rocks that will sit in front of the house and provide an obstacle for the other team's stones. Alternatively, guards can be used to defend your stones that are already in the house from being knocked out by the other team's "takeout" shots.

The third major type of curling shot is the "draw," a shot that's meant to avoid other stones and come to rest in the house. Generally, a draw is used with the hope of scoring points, a guard is thrown to protect the house or a stone that's already been thrown, and a takeout is used defensively.

Yes you may.

What’s the Difference Between a Primary and a Caucus?

Leading up to a U.S. presidential election, each state (and territory) must vote to decide which candidates it wants to compete in that election—but how exactly that decision happens differs from state to state. Some have primaries, while others hold caucuses.

A primary is a relatively straightforward process that resembles any other election. Essentially, you go to your designated polling station, which could be anywhere from a school to a sports complex, and check your favorite candidate on a ballot. Generally, any candidate who receives at least 15 percent of the votes is eligible to earn delegates, the elected officials who vote to decide whom to choose as the party’s presidential nominee at the national convention. Those delegates are then divided among eligible candidates in proportion to how many votes they earned. Since primaries are short and simple, almost all states and territories use them to help choose presidential nominees these days.

However, there are several holdouts that still opt for caucuses, a more manual (and more complicated) voting process with roots in late 18th-century American elections. During a Democratic caucus, participants arrive at a local venue and split up into groups based on which candidate they’re supporting; there’s usually a group for undecided voters, too. Volunteers count how many people are in each group, and—similar to primaries—any candidate who has at least 15 percent of the supporters is deemed “viable,” or eligible to earn delegates. Unlike primaries, caucuses don’t end after that initial tally. Supporters of candidates who didn’t meet the 15-percent threshold can then join groups for viable candidates; volunteers do a recount, and delegates are apportioned based on those updated numbers. Republican caucuses are similar, only the voting happens on an informal private ballot.

If your state holds a primary, there’s a pretty good chance you can get in and out without talking to more than a person or two—and it could even come as a surprise if someone tries to persuade you to vote for a certain candidate. At Democratic caucuses, on the other hand, that’s an integral part of the process. Before the initial count, people try to convince undecided voters to join their group (or supporters of a candidate who looks like they might not reach the viability threshold), and after the initial count, another wave of campaigning happens in order to claim supporters of unviable candidates. This, in addition to all the manual counting and re-counting, means that caucus attendees can count on being there for hours longer than primary participants.

Caucuses are a great way to see how citizens really feel about presidential hopefuls on a deeper, more personal level than polls and stats are often able to tell us, but the overall hassle—not to mention the fear of inaccurate vote-counting—has caused more and more states to switch to primaries in recent years. As Business Insider reports, there are only eight places that are still holding caucuses in 2020: Iowa, Nevada, North Dakota, Wyoming, Kentucky (Republican only), American Samoa, the Virgin Islands, and Guam.

Because Iowa’s caucuses are always first on the schedule, they’re often considered a little more important than some others—find out why here.

Why Isn't Fish Considered Meat During Lent?

For six Fridays each spring, Catholics observing Lent skip sirloin in favor of fish sticks and swap Big Macs for Filet-O-Fish. Why?

Legend has it that centuries ago a medieval pope with connections to Europe's fishing business banned red meat on Fridays to give his buddies' industry a boost. But that story isn't true. Sunday school teachers have a more theological answer: Jesus fasted for 40 days and died on a Friday. Catholics honor both occasions by making a small sacrifice: avoiding animal flesh one day out of the week. That explanation is dandy for a homily, but it doesn't explain why only red meat and poultry are targeted and seafood is fine.

For centuries, the reason evolved with the fast. In the beginning, some worshippers only ate bread. But by the Middle Ages, they were avoiding meat, eggs, and dairy. By the 13th century, the meat-fish divide was firmly established—and Saint Thomas Aquinas gave a lovely answer explaining why: sex, simplicity, and farts.

In Part II of his Summa Theologica, Aquinas wrote:

"Fasting was instituted by the Church in order to bridle the concupiscences of the flesh, which regard pleasures of touch in connection with food and sex. Wherefore the Church forbade those who fast to partake of those foods which both afford most pleasure to the palate, and besides are a very great incentive to lust. Such are the flesh of animals that take their rest on the earth, and of those that breathe the air and their products."

Put differently, Aquinas thought fellow Catholics should abstain from eating land-locked animals because they were too darn tasty. Lent was a time for simplicity, and he suggested that everyone tone it down. It makes sense. In the 1200s, meat was a luxury. Eating something as decadent as beef was no way to celebrate a holiday centered on modesty. But Aquinas had another reason, too: He believed meat made you horny.

"For, since such like animals are more like man in body, they afford greater pleasure as food, and greater nourishment to the human body, so that from their consumption there results a greater surplus available for seminal matter, which when abundant becomes a great incentive to lust. Hence the Church has bidden those who fast to abstain especially from these foods."

There you have it. You can now blame those impure thoughts on a beef patty. (Aquinas might have had it backwards though. According to the American Dietetic Association, red meat doesn't boost "seminal matter." Men trying to increase their sperm count are generally advised to cut back on meat. However, red meat does improve testosterone levels, so it's give-and-take.)

Aquinas gave a third reason to avoid meat: it won't give you gas. "Those who fast," Aquinas wrote, "are forbidden the use of flesh meat rather than of wine or vegetables, which are flatulent foods." Aquinas argued that "flatulent foods" gave your "vital spirit" a quick pick-me-up. Meat, on the other hand, boosts the body's long-lasting, lustful humors—a religious no-no.

But why isn't fish considered meat?

The reason is foggy. Saint Paul's first letter to the Corinthians, for one, has been used to justify fasting rules. Paul wrote, " … There is one kind of flesh of men, another flesh of beasts, another of fish, and another of birds" (15:39). That distinction was possibly taken from Judaism's own dietary restrictions, which separates fleishig (which includes land-locked mammals and fowl) from pareve (which includes fish). Neither the Torah, Talmud, or New Testament clearly explains the rationale behind the divide.

It's arbitrary, anyway. In the 17th century, the Bishop of Quebec ruled that beavers were fish. In Latin America, it's OK to eat capybara, as the largest living rodent is apparently also a fish on Lenten Fridays. Churchgoers around Detroit can guiltlessly munch on muskrat every Friday. And in 2010, the Archbishop of New Orleans gave alligator the thumbs up when he declared, “Alligator is considered in the fish family."

Thanks to King Henry VIII and Martin Luther, Protestants don't have to worry about their diet. When Henry ruled, fish was one of England's most popular dishes. But when the Church refused to grant the King a divorce, he broke from the Church. Consuming fish became a pro-Catholic political statement. Anglicans and the King's sympathizers made it a point to eat meat on Fridays. Around that same time, Martin Luther declared that fasting was up to the individual, not the Church. Those attitudes hurt England's fishing industry so much that, in 1547, Henry's son King Edward VI—who was just 10 at the time—tried to reinstate the fast to improve the country's fishing economy. Some Anglicans picked the practice back up, but Protestants—who were strongest in Continental Europe—didn't need to take the bait.
