Why Can’t You Wear White After Labor Day?

Wearing white in the summer makes sense. Desert peoples have known for thousands of years that white clothing seems to keep you a little bit cooler than other colors. But wearing white only during the summer? While no one is completely sure exactly when or why this fashion rule came into effect, our best guess is that it had to do with snobbery in the late 1800s and early 1900s.

The wives of the super-rich ruled high society with an iron fist after the Civil War. As more and more people became millionaires, though, it was difficult to tell the difference between respectable old money families and those who only had vulgar new money. By the 1880s, in order to tell who was acceptable and who wasn’t, the women who were already “in” felt it necessary to create dozens of fashion rules that everyone in the know had to follow. That way, if a woman showed up at the opera in a dress that cost more than most Americans made in a year, but it had the wrong sleeve length, other women would know not to give her the time of day.

Not wearing white outside the summer months was another one of these silly rules. White was for weddings and resort wear, not dinner parties in the fall. Of course it could get extremely hot in September, and wearing white might make the most sense, but if you wanted to be appropriately attired you just did not do it. Labor Day became a federal holiday in 1894, and society eventually adopted it as the natural endpoint for summer fashion.

Not everyone followed this rule. Even some socialites continued to buck the trend, most famously Coco Chanel, who wore white year-round. But even though the rule was originally enforced by only a few hundred women, over the decades it trickled down to everyone else. By the 1950s, women’s magazines made it clear to middle class America: White clothing came out on Memorial Day and went away on Labor Day.

These days the fashion world is much more relaxed about what colors to wear and when, but every year you will still hear people say that white after Labor Day is unacceptable, all thanks to some snobby millionaires who decided that was a fashion no-no more than 100 years ago.

Big Questions
Are There Number 1 Pencils?

Almost every syllabus, teacher, and standardized test points to the ubiquitous No. 2 pencil, but are there other choices out there?

Of course! Pencil makers manufacture No. 1, 2, 2.5, 3, and 4 pencils—and sometimes other intermediate numbers. The higher the number, the harder the core and lighter the markings. (No. 1 pencils produce darker markings, which are sometimes preferred by people working in publishing.)

The current style of production is profiled after pencils developed in 1794 by Nicolas-Jacques Conté. Before Conté, pencil hardness varied from location to location and maker to maker. The earliest pencils were made by filling a wood shaft with raw graphite, leading to the need for a trade-wide recognized method of production.

Conté’s method involved mixing powdered graphite with finely ground clay; that mixture was shaped into a long cylinder and then baked in an oven. The proportion of clay versus graphite added to a mixture determines the hardness of the lead. Although the method may be agreed upon, the way various companies categorize and label pencils isn't.

Today, many U.S.  companies use a numbering system for general-purpose, writing pencils that specifies how hard the lead is. For graphic and artist pencils and for companies outside the U.S., systems get a little complicated, using a combination of numbers and letters known as the HB Graphite Scale.

"H" indicates hardness and "B" indicates blackness. Lowest on the scale is 9H, indicating a pencil with extremely hard lead that produces a light mark. On the opposite end of the scale, 9B represents a pencil with extremely soft lead that produces a dark mark. ("F" also indicates a pencil that sharpens to a fine point.) The middle of the scale shows the letters and numbers that correspond to everyday writing utensils: B = No. 1 pencils, HB = No. 2, F = No. 2½, H = No. 3, and 2H = No. 4 (although exact conversions depend on the brand).

So why are testing centers such sticklers about using only No. 2 pencils? They cooperate better with technology because early machines used the electrical conductivity of the lead to read the pencil marks. Early scanning-and-scoring machines couldn't detect marks made by harder pencils, so No. 3 and No. 4 pencils usually resulted in erroneous results. Softer pencils like No. 1s smudge, so they're just impractical to use. So No. 2 pencils became the industry standard.

Big Questions
What Are Curlers Yelling About?

Curling is a sport that prides itself on civility—in fact, one of its key tenets is known as the “Spirit of Curling,” a term that illustrates the respect that the athletes have for both their own teammates and their opponents. But if you’re one of the millions of people who get absorbed by the sport once every four years, you probably noticed one quirk that is decidedly uncivilized: the yelling.

Watch any curling match and you’ll hear skips—or captains—on both sides barking and shouting as the 42-pound stone rumbles down the ice. This isn’t trash talk; it’s strategy. And, of course, curlers have their own jargon, so while their screams won’t make a whole lot of sense to the uninitiated, they could decide whether or not a team will have a spot on the podium once these Olympics are over.

For instance, when you hear a skip shouting “Whoa!” it means he or she needs their teammates to stop sweeping. Shouting “Hard!” means the others need to start sweeping faster. If that’s still not getting the job done, yelling “Hurry hard!” will likely drive the point home: pick up the intensity and sweep with downward pressure. A "Clean!" yell means put a brush on the ice but apply no pressure. This will clear the ice so the stone can glide more easily.

There's no regulation for the shouts, though—curler Erika Brown says she shouts “Right off!” and “Whoa!” to get her teammates to stop sweeping. And when it's time for the team to start sweeping, you might hear "Yes!" or "Sweep!" or "Get on it!" The actual terminology isn't as important as how the phrase is shouted. Curling is a sport predicated on feel, and it’s often the volume and urgency in the skip’s voice (and what shade of red they’re turning) that’s the most important aspect of the shouting.

If you need any more reason to make curling your favorite winter sport, once all that yelling is over and a winner is declared, it's not uncommon for both teams to go out for a round of drinks afterwards (with the winners picking up the tab, obviously). Find out how you can pick up a brush and learn the ins and outs of curling with our beginner's guide.
