Watch: Why Are I-Beams Shaped Like the Letter I?

English speakers know it as an “I-beam” for its similarity to the capital letter “I” (with serifs). In many European languages it’s a “double-T” beam. Or you may know it as an “H-beam.” In any case, this beam is the support structure for tons of modern buildings. So why is it shaped that way?

Long story short, the combination of the “web” (the middle bit of the beam) and the “flange” (the top and bottom bits) offers resistance both to shear and bending forces. Watch this short video for the math behind the engineering you’re probably sitting on right now:

Important note: In the video, there is a typo in the max deflection formula shown. The numerator shown should include L to the fourth power, not third. (On desktop browsers, an annotation fixes this, but on mobile it often doesn’t show up!) If you’re not into video explanations, Wikipedia’s page on I-beams is pretty solid. For more videos like this, check out Real Engineering on YouTube.

15 Things You May Not Have Known About ‘Scream’

Image credit: 
Dimension Films

We won’t spoil the big reveal in Scream, which was released 20 years ago today, but even if you know the ending of Wes Craven’s horror masterpiece, these facts may be able to shock you.

1. THE ORIGINAL TITLE OF THE FILM WAS SCARY MOVIE.

The original title of the film was Scary Movie, but it was changed to Scream by the Weinstein brothers—then the heads of the film’s production company, Miramax—in the middle of production. They allegedly decided on the change because Harvey Weinstein was listening to the Michael Jackson song “Scream” in his car with his brother Bob. They both liked the title for a horror movie.

2. IT WAS PARTIALLY INSPIRED BY A REAL-LIFE STORY.

Screenwriter Kevin Williamson was partially inspired by a real life series of student murders in Gainesville, Florida in 1990, perpetrated by killer Danny Harold Rolling who was later dubbed “The Gainesville Ripper.” Williams was also inspired by John Carpenter’s 1978 horror classic, Halloween, his favorite movie.

3. THE SCRIPT SPARKED A MAJOR BIDDING WAR.

Williamson’s self-referential script sparked a fierce bidding war in Hollywood between five movie studios before Williamson ultimately accepted Dimension Films’ $400,000 offer to buy the screenplay.

4. IT COULD HAVE BEEN DIRECTED BY GEORGE ROMERO, OR SAM RAIMI.

The Weinstein brothers initially approached noted horror directors George A. Romero and Sam Raimi for directorial duties, but they both turned the project down. Wes Craven, who had directed the original A Nightmare on Elm Street, initially passed as well, but he signed on to direct after Drew Barrymore agreed to appear in the film in the lead role of Sidney Prescott.

5. DREW BARRYMORE WAS SET TO STAR, BUT CHANGED HER MIND.

Barrymore changed her mind about playing the lead five weeks before production was set to begin. Barrymore instead suggested she play Casey Becker, the teen terrorized by the killer in the opening scene, to cleverly subvert audience expectations that a star of her stature would survive the movie. Casting directors approached Alicia Witt, Brittany Murphy, and Reese Witherspoon to take over the Sidney Prescott role before eventually casting Neve Campbell.

6. BARRYMORE WORKED FOR LESS THAN A WEEK.

Barrymore shot all of her scenes in the first five days of production.

7. THE FILM’S ICONIC MASK WAS FOUND DURING A LOCATION SCOUT.

The killer’s now-iconic mask was a simple off-the-shelf Halloween mask. Craven and a producer found it at a house they were location scouting.

8. BOB WEINSTEIN WASN’T CONVINCED THAT THE MASK WAS SCARY ENOUGH.

Bob Weinstein initially thought the killer’s mask wasn’t scary enough and considered replacing Craven as director. But Craven and editor Patrick Lussier created a workprint out of dailies of the opening scene that convinced Weinstein to quickly change his mind.

9. THE VOICE BEHIND THE KILLER IS VETERAN VOICE ACTOR ROGER L. JACKSON.

Besides Scream, Jackson’s credits include the role of Mojo Jojo from The Powerpuff Girls. Craven separated Jackson from the actors and had him actually talk to them over the phone to make their reactions feel more genuine.

10. LINDA BLAIR HAD A CAMEO.

Linda Blair, the star of The Exorcist, makes a cameo as one of the news reporters outside of the school. She’s the one with the bright orange blouse. Later on, she’s the reporter who confronts Sidney in Dewey’s police car. Craven previously directed Blair in the 1978 TV movie Stranger in Our House.

11. THE HIGH SCHOOL THEY PLANNED TO SHOOT AT CHANGED ITS MIND ABOUT THE PRODUCTION.

The high school scenes were originally supposed to be shot at Santa Rosa High School in Santa Rosa, Calif. But despite getting approval from the school’s administration, the city school board banned the production weeks before the shoot began over concerns that the script glorified violence. 

12. THE HIGH SCHOOL IS ACTUALLY A COMMUNITY CENTER.

Eventually, the high school scenes were shot at a community center in nearby Sonoma because it didn’t fall under the jurisdiction of a school board. As a joke, in the “Special Thanks” section of the end credits it says “No thanks whatsoever to the Santa Rosa city school district governing board.”

13. WES CRAVEN HAS A CAMEO.

Director Wes Craven makes a cameo as a janitor. He’s wearing Freddy Krueger’s hat and sweater.

14. THE FINAL SCENE TOOK 21 NIGHTS TO SHOOT.

The 42-minute final act, taking place entirely during the party at Stu’s house, took 21 successive nights to shoot. The cast and crew jokingly called it “The longest night in horror history.”

15. IT WAS INITIALLY SLAPPED WITH AN NC-17 RATING.

The film was originally given an NC-17 rating by the MPAA for being too gruesome, and despite the fact that Craven initially refused to cut anything, the movie was edited and resubmitted by the studio nine times before it was given an R rating.

30 Facts About Your Favorite Steven Spielberg Movies

Image credit: 
Nicholas Hunt/Getty Images

Since making his feature directorial debut with the 1971 TV movie Duel, Steven Spielberg—who was born on this day in 1946—has gone on to create some of Hollywood’s most iconic films. In 1975, he singlehandedly invented “the summer blockbuster” when Jaws racked up nearly half a billion dollars worldwide. In the years since, Spielberg has directed a few other films you might have heard of, including Close Encounters of the Third Kind, Jurassic Park, Saving Private Ryan, Schindler’s List, E.T., and Lincoln. In honor of the Oscar-winning director’s 70th birthday, here are 30 things you might not have known about some of his most famous films.

1. DANIEL DAY-LEWIS IS THE FIRST ACTOR TO WIN AN OSCAR FOR ONE OF SPIELBERG’S MOVIES.

Plenty of actors have been nominated for their work in Spielberg’s movies, but it wasn’t until 2013—when Daniel Day-Lewis took home the Best Actor Oscar for his work in Lincoln—that Spielberg directed any actor to an actual Academy Award win.

2. THERE’S NOT A LOT OF JAWS IN JAWS.

The shark doesn’t fully appear in a shot until one hour and 21 minutes into the two-hour film. The reason it isn’t shown is because the mechanical shark that was built rarely worked during filming, so Spielberg had to create inventive ways (like Quint’s yellow barrels) to shoot around the non-functional shark.

3. HE CONSIDERS DUEL AN INDICTMENT OF MACHINES.

When asked about his first feature, Duel, Spielberg described it as “an indictment of machines. And I determined very early on that everything about the film would be the complete disruption of our whole technological society.”

4. CLOSE ENCOUNTERS OF THE THIRD KIND WAS INITIALLY A VERY DIFFERENT FILM.

Spielberg’s initial story outline involved UFOs and shady government dealings following the Watergate scandal, which became a script entitled “Watch the Skies.” The idea involved a police or military officer working on Project Blue Book, the Air Force’s official study into UFOs in the 1950s and 1960s, who would become the whistleblower on the government cover-up of aliens. There were numerous rewrites—Taxi Driver scribe Paul Schrader even took a crack at it, penning a political UFO thriller titled “Kingdom Come” that Spielberg and the movie studio rejected—before the story we know today emerged.

5. IF HE HAD TO MAKE THE SUGARLAND EXPRESS AGAIN, HE’D DO IT COMPLETELY DIFFERENTLY.

“That’s the one film that I can honestly say, if I had to do it all over again I’d make Sugarland Express in a completely different fashion,” Spielberg said of the 1974 crime drama.

6. E.T. WAS INITIALLY PATCHED TOGETHER FROM DIFFERENT IDEAS FOR SEPARATE MOVIES.

With his newfound success following the back-to-back smash hits of Jaws in 1975 and Close Encounters of the Third Kind in 1977, Spielberg wanted to tell a smaller, more personal story for his next film. Entitled Growing Up, the proposed movie was inspired by the divorce of his parents when he was 15 years old. It included the feelings of alienation Spielberg felt being Jewish in an all Gentile neighborhood in Arizona and was told from the perspective of three children.

When the project was shelved, Spielberg moved on to another big budget film, 1941, but the basic idea stayed with him. Around the same time, Columbia Pictures demanded a sequel to Close Encounters. Spielberg wanted no part of that, though he had a small idea about what would have happened if an alien didn’t go back to the mothership at the end of that movie. To ensure they didn’t make the sequel without him, he instead commissioned writer/director John Sayles to create a script for a pseudo-sequel called Night Skies, about a suburban family terrorized by a group of aliens with one befriending the family’s son.

The project was too dark in tone for Spielberg, though, and ultimately, he had Columbia just re-release Close Encounters in a Special Edition with additional scenes. But he still recognized the potential of a film like Night Skies, so he and screenwriter Melissa Mathison then combined Spielberg’s semi-autobiographical story with the benevolent alien visiting a boy on earth to create E.T. The idea of the terrorized family was refashioned as another eventual Spielberg production: Poltergeist.   

7. TOM SELLECK WAS SUPPOSED TO PLAY INDIANA JONES.

Prior to the production’s start date in May 1980, George Lucas and Spielberg set up shop in the old Lucasfilm corporate headquarters to begin the casting process. Actors and actresses in consideration for the lead roles of Indiana Jones and his tough but beautiful companion Marion Ravenwood included Jane Seymour, Debra Winger, Mark Harmon, Mary Steenburgen, Michael Biehn, Sam Shepard, Valerie Bertinelli, Bruce Boxleitner, Sean Young, Don Johnson, Dee Wallace (who would later go on to star as the mother in Spielberg’s E.T.), Barbara Hershey, and even David Hasselhoff.

For Indy, Lucas and Spielberg eventually settled on actor Tom Selleck. But when CBS got wind of what the two were up to, the network legally barred Selleck—the lead of the hit show Magnum, P.I.—from appearing in the film. Spielberg then suggested Harrison Ford as a quick replacement, but Lucas was reluctant to cast Ford because he was already Han Solo in his Star Wars films. But Spielberg’s quick thinking prevailed, and Ford was added to the cast just two weeks before principal photography began. (A similar snafu happened with Danny DeVito, the first choice to play Indy’s jovial companion Sallah, who couldn’t take the part due to his contractual obligation to appear on the popular ABC show Taxi.)

8. SPIELBERG DIDN’T THINK 1941 WAS FUNNY ENOUGH.

Much has been made out of the bomb that was Spielberg’s attempt at more of a straight comedy, the 1979 war comedy 1941. But the director himself has a pretty good handle on what went wrong with the film. “What happened on the screen was pretty out of control,” he said, “but the production was pretty much in control. I don’t dislike the movie at all. I’m not embarrassed by it—I just think that it wasn’t funny enough.”

9. A KING KONG RIDE INSPIRED SPIELBERG’S ORIGINAL PLAN FOR BUILDING THE DINOSAURS IN JURASSIC PARK.  

The logistics of Spielberg’s original plans to bring the dinosaurs to life were inspired by the Universal Studios “King Kong Encounter” ride. Disney Imagineer Bob Gurr designed Kong as a full-size animatronic with an inflatable balloon-like skin surrounding a wire frame. Unfortunately, the plans to build all of Jurassic Park‘s dinosaurs as similarly full-size animatronics proved too costly.

10. HE DIRECTED INDIANA JONES AND THE TEMPLE OF DOOM OUT OF JEALOUSY.

After finding great success with—and loving the experience of directing—Raiders of the Lost Ark, Spielberg’s main motivation for stepping behind the camera for its sequel, 1984’s Indiana Jones and the Temple of Doom, was jealousy. “I got separation pangs,” said Spielberg. “I knew that if I didn’t direct Temple, someone else would. I got a little bit jealous, and I got a little bit frustrated.”

11. INDIANA JONES AND THE LAST CRUSADE WAS AN APOLOGY FOR TEMPLE OF DOOM.

“I’m making the third Indiana Jones movie to apologize for the second,” Spielberg announced. “It was too horrific.”

12. SPIELBERG REFUSED TO ACCEPT A SALARY FOR SCHINDLER’S LIST.

Though Spielberg is already an extremely wealthy man as a result of the many big-budget movies that have made him one of Hollywood’s most successful directors, he decided that a story as important as Schindler’s List shouldn’t be made with an eye toward financial reward. The director relinquished his salary for the movie and any proceeds he would stand to make in perpetuity, calling any such personal gains “blood money.” Instead, Spielberg used the film’s profits to found the Shoah Foundation, which was established to honor and remember the survivors of the Holocaust by collecting personal recollections and audio visual interviews.

13. THE MOST IMPORTANT THING ABOUT THE COLOR PURPLE WAS ITS CHARACTERS.

“The big difference in The Color Purple is that the story is not bigger than the lives of these people,” Spielberg said of his Oscar-nominated adaptation of Alice Walker’s novel. “I didn’t want to make another movie that dwarfs the characters. But here the characters are the story.”

14. SAVING PRIVATE RYAN IS PARTLY BASED ON A TRUE STORY.

Contrary to popular belief, Saving Private Ryan is not based on the Sullivan brothers, a group of five brothers who were all killed in action while serving in the US Navy during World War II on the USS Juneau. The movie is actually based on the Niland brothers, four siblings who all served in the US Army during World War II. Three brothers—Robert, Preston, and Edward—were supposedly killed in action, which caused their remaining brother, Fritz (whom the titular Private Ryan was based on) to be shipped back to America so that the Niland family wouldn’t lose all of their sons. Edward, who was originally thought dead, was actually found alive after escaping a Japanese prison camp in Burma, making two surviving brothers out of the four who fought in the war.

15. AMISTAD BECAME TOO MUCH OF A HISTORY LESSON.

“I kind of dried it out,” Spielberg said of 1997’s Amistad, which failed to capture a huge audience. “It became too much of a history lesson.”

16. MINORITY REPORT WAS ORIGINALLY INTENDED AS A SEQUEL TO TOTAL RECALL.

Total Recall was another movie adaptation of a Philip K. Dick story. The Minority Report movie rights were held by cinematographer-turned-director Jan de Bont (Speed, Twister) at one point, who ended up getting a producer credit on the film without ever setting foot on set. Eventually Cruise approached Spielberg about an early version of the script, written for de Bont by Jon Cohen, which Spielberg hired Scott Frank to rewrite. When Cruise and Speilberg’s schedules were finally both clear at the same time, they went to work.

17. THE REAL FRANK ABAGNALE, JR. WAS PLEASED WITH CATCH ME IF YOU CAN.

“I wasn’t very involved with the making of the film, but I thought Spielberg did a great job and only changed very minor things,” Frank Abagnale, Jr., the inspiration for Catch Me If You Can, told WIRED. “In real life I had two brothers and a sister, he chose to portray me as an only child. In real life there was a back and forth relationship with my father (Christopher Walken in the film) but in real life once I ran away from home I never saw my parents again and my father passed away while I was in prison. And when I escaped from the aircraft I escaped from kitchen galley where they service the plane, but in the movie they had me escape from the toilet. But other than very minor things, I thought he stayed very straight to the story.”

18. JAWS ORIGINALLY ENDED JUST LIKE MOBY DICK.

The original ending in the script had the shark dying of harpoon injuries inflicted by Quint and Brody à la Moby Dick, but Spielberg thought the movie needed a crowd-pleasing finale and came up with the exploding tank as seen in the final film. The dialogue and foreshadowing of the tank were then dropped in as they shot the movie.

19. HE CONSIDERS EMPIRE OF THE SUN HIS DARKEST FILM.

The 1987 World War II drama, which introduced Christian Bale to the world, was a bit of a departure for Spielberg. “I made a movie to satisfy me, not the audience,” the director said of his choice to delve into darker terrain. “It’s as dark as I’ve allowed myself to get.”

20. GARTH BROOKS NEARLY PLAYED PRIVATE JACKSON IN SAVING PRIVATE RYAN.

Frank Darabont was hired to do uncredited rewrites on Saving Private Ryan, and created the role of the Bible-quoting sniper, Private Jackson, to be played by country singer Garth Brooks. Brooks dropped out of the movie after Spielberg came onboard and cast Tom Hanks in the lead role. Apparently Brooks didn’t want to play second fiddle to Hanks, but Spielberg offered him a chance to play another role of his choosing. Instead of a specific role, Brooks allegedly said he wanted to play the “bad guy,” but in Saving Private Ryan there is no real bad guy other than the entire Wehrmacht, so Spielberg ultimately decided to drop Brooks from the movie.

21. WAR OF THE WORLDS WASN’T INTENDED AS A FAMILY MOVIE.

“I never made War of the Worlds for a family audience,” Spielberg said of his 2005 adaptation of H. G. Wells’ novel. “It was a very intense post-9/11 apocalyptic movie about the end of everything.”

22. EVERYTHING IN THE FAMOUS SHOT OF ELLIOTT AND E.T. FLYING ACROSS THE FACE OF THE MOON WAS REAL—EXCEPT ELLIOTT AND E.T.

Visual effects supervisor Dennis Muren and his team at Industrial Light and Magic were tasked with creating organic special effects to surround the potentially inorganic looking E.T. puppet. Surprisingly, the iconic shot of the boy and alien flying across the full moon was mostly a “real” shot. It took Muren and his team weeks to find the right spot to film a low moon among trees, so they used maps and charts to coordinate the scene once they found the right spot. In the shot, Elliott and E.T. are puppets that were added with special effects in post-production, but the rest is photo-real.

23. ONE QUARTER OF THE BUDGET FOR MINORITY REPORT WAS FINANCED BY PRODUCT PLACEMENTS.

Toyota paid $5 million to get a futuristic Lexus called the Mag-Lev in Minority Report. Nokia shelled out $2 million for the characters to wear Nokia headsets. The Gap, Pepsi, American Express, and Reebok got in on the sci-fi action, too.

24. JURASSIC PARK BROKE NEW CG GROUND.

Spielberg wasn’t 100 percent happy with the wide test shots of the dinosaurs—they just weren’t photorealistic enough. So Muren and his ILM team, spurred by their revolutionary experience in designing and incorporating fully computer-generated characters into films like The Abyss and Terminator 2: Judgment Day, showed Spielberg an early CGI dino test of a group of Gallimimus skeletons running through a field. Spielberg was in awe of the ease of movement and realism of the effects, but he was still wary that they wouldn’t hold up under intense scrutiny—and he didn’t want to scrap Tippett’s practical animation talents altogether. So the director urged Muren and ILM to go further. When they came back with a CG test of a fully rendered T. rex walking across a field in broad daylight, the director decided to go full CGI for some shots.

25. SCHINDLER’S LIST IS TECHNICALLY A STUDENT FILM.

Thirty-three years after dropping out of college, Steven Spielberg finally received a B.A. in Film and Video Production from his newly minted alma mater, Cal State Long Beach, in 2002. The director re-enrolled in secret, and gained his remaining credits by writing essays and submitting projects under a pseudonym. In order to pass a film course, he submitted Schindler’s List as his student project. Spielberg describes the time gap between leaving school and earning his degree as his “longest post-production schedule.”

26. THE IMPORTANCE OF BRINGING LINCOLN TO THE SCREEN WAS SERIOUS BUSINESS.

“We were playing with one of the most beloved, and mysterious, characters in American history,” Spielberg said of 2013’s Lincoln. “I wanted to make sure that everybody on the film understood that.”

27. MUNICH WAS MEANT TO BE “A PRAYER FOR PEACE.”

Spielberg described 2005’s Munich as “a prayer for peace. I was always thinking about that as I was making the picture.”

28. SPIELBERG TOLD CRUISE NOT TO TAKE A SALARY FOR MINORITY REPORT.

At the time, Spielberg claimed that he had not taken a salary on a movie in 18 years. And he wanted Cruise to do the same. Instead, the two reportedly agreed to receiving no upfront money in exchange for approximately 15 percent of the box office apiece. (The film made more than $358 million worldwide.)

29. THE D-DAY SEQUENCE IN SAVING PRIVATE RYAN COST A WHOLE LOT OF MONEY.

The D-Day scene alone cost $12 million because of the logistical difficulties and the realistic scope needed to complete the sequence. The entire budget of the movie was only $70 million. Spielberg didn’t storyboard any of the D-Day sequence.  

30. THE MEMORABLE 5-NOTE TONES IN CLOSE ENCOUNTERS TOOK A LONG TIME TO FIGURE OUT.

Composer John Williams worked with Spielberg to come up with the movie’s distinct five-note musical method of communication between humans and aliens—which Spielberg partly based on the Solfège system of musical education—a year before shooting began.

Williams initially wanted a seven-note sequence, but it was too long for the simple musical “greeting” Spielberg wanted. The composer enlisted a mathematician to calculate the number of five-note combinations they could potentially make from a 12-note scale. When that number proved to be somewhere upwards of 134,000 combinations, Williams created 100 distinct versions, and they simply whittled the combinations down one by one until they had a winner.

In this 20-minute video, two mathematicians play Monopoly and work out how to win at it…using math.

The mathematicians are Dr. Hannah Fry and Matt Parker. They each simulated the game using computer programs they wrote. The programs play pseudo-Monopoly games, keeping track of how the dice rolls come out (including how common doubles are), which properties are commonly landed on, and how the Chance and Community Chest decks are used.

With all this data, the two work out how to win money and infuriate your relatives. Enjoy:

If you’re curious about Fry’s book including Monopoly bits—or the “finite money” goof in the video—check the YouTube video description for links and explanation.

Scented Candles Let You Bring the Smell of National Parks Home With You

filed under: fun, shopping

UncommonGoods

Scents have the power to transport us to specific places or times. Some candles can remind you of specific locations, while others can stir up nostalgic memories of home. If you find yourself longing for the great outdoors, a series of candles from Uncommon Goods promise to make it feel like you’re really in one of the U.S. national parks—so long as you close your eyes.

The Great Outdoors National Park Candles are inspired by key tourist spots in Yosemite, Yellowstone, and Redwood National. Creator Laura Reid visited the three national parks and researched the distinct scents in an attempt to fully recreate what each place smells like. The result: Yellowstone’s Old Faithful smells of subalpine fir, thermal moss, and wild strawberry; Yosemite’s Firefall is reimagined with brisk granite, fresh cedar, and black sage; Redwood National’s Avenue of the Giants has notes of coastal redwood, bay laurel, and sea salt. Each of the layered scents are made with essential oils in hand-poured coconut wax.

You can grab one of these scenic candles from UncommonGoods for $40.

17 Russian Travel Tips for Visiting America

filed under: travel
Image credit:

Here are some things Russians think other Russians who are preparing to visit the U.S. should know.

1. Don’t Worry About Bringing Gifts to Americans …

Gift giving isn’t a big deal to Americans. In fact, according to the site Деловой этикет по-американски, “Americans do not expect them. On the contrary, an unexpected gift while conducting business can put an American in an awkward position. Such things for Americans suggest reciprocity.” But not all gifts will make Americans feel awful. They love gifts that are “purely Russian,” with some caveats:

If you do gift, it is desirable to bring something purely Russian when you visit the United States. But make it ‘purely Russian’ for modern America—not nesting dolls and samovar. Instead bring a good book about Moscow or Russian history, art and culture. Americans appreciate a good education and have great respect for cognitive literature.

2. … And definitely don’t bring business gifts.

“Business gifts in the U.S. are not acceptable,” the site Национальные особенности этикета в США cautions. “[T]hey often cause suspicion. Americans fear that they could be construed as a bribe, and in the United States that is strictly punishable by law.”

3. If you’re a man, be careful when dealing with American ladies.

According to the Russian site Этикет США, “U.S. etiquette prohibits flirting with a woman who is not your girlfriend or wife. If you are not acquainted with a woman, whether she be in a restaurant, on the street, or on the subway, do not look at her legs, etc. Americans could easily call the police on you, even for just ogling her.”

When it comes to introducing yourself to a woman, the site Национальные особенности этикета в США advises caution. You shouldn’t kiss her, not even her hand:

Welcome and introductions: men and women tend to shake hands. Mutual kissing and kissing ladies’ hands is not accepted. Also, women play a greater role in business. Often they insist to be treated exactly as an equal and not as a lady. In this regard, it is not acceptable to be excessively gallant, and you should avoid personal questions (do not find out whether she is married).

4. They’d prefer it if you got to the point …

“Americans generally do not like long intros and prefer to go directly to the subject matter, especially if it’s a phone conversation,” says the site Американский речевой этикет. “In Russia we talk about general topics before moving on to the reason for the call.”

That said, once you’re having a phone conversation, Americans won’t be thrilled if you just hang up on them. “Americans are often surprised by the Russian habit of quickly breaking off a conversation and hanging up,” the site notes. “Phone etiquette in America usually involves the gradual end of the conversation, confirmation agreements and standard closing remarks. By the way, ‘see you later’ should not be taken literally. That is a courtesy, and no more.”

5. … But would like you to avoid pointed statements.

According to Американский речевой этикет, “Russian conversational patterns often sound harsh to Americans. Statements such as, ‘You’re wrong,’ can be offensive. This can be interpreted as ‘You are telling lies!'” Instead, soften it up: “[I]t is better to say, ‘I do not think I can agree with this.'”

6. You Can Only Talk About Health in Certain Situations.

And that situation is when your friend is in the hospital. Otherwise, according to the site Американский речевой этикет, “What seems caring can be regarded as an invasion of privacy, lack of tact. You have to have some justification to show interest in their health.” Finally, the site notes, “Do not ask the effect of a magnetic storm (not many Americans know what that is) on their well-being.”

7. When your American friend invites you to a picnic, bring something sporty (and maybe a flask).

The site Деловой этикет по-американски discusses a hypothetical situation in which a Russian visitor to the United States is invited on the most American of outings: The Picnic. (This will only happen “if you’ve known each other for several years and are social outside the office,” though, so probably won’t be an option for the novice traveler.) According to the site, “As a rule, the invitation will be only on a weekend, and you don’t have to prepare for something extravagant. Everything is the same as ours, only with far less booze. Bring something sporty—ball, badminton, Americans are certainly fervent fans of these things.” Our tip: Russians concerned about the dearth of booze should bring their own in a flask.

8. Don’t be weirded out if Americans put their feet up on stuff.

“When Americans are talking, they might put their foot on a nearby chair, or even a table,” says the site Национальные особенности этикета в США. “They might cross their legs so that one foot rests on the opposite knee. In American culture, it is considered an acceptable norm, but often causes irritation in other countries.”

9. Americans are very optimistic …

“Americans and Russians say different things when faced with the same situation,” notes the site Американский речевой этикет. “Seeing the man who had fallen in the street, an American asks, ‘Are you all right?’ Russians will inquire: ‘Are you ill?’ We see a victim of the incident; they see survivors. Survivors are perceived as heroes. Where we ‘aren’t sick,’ they ‘stay well.’ We discuss the problem. They discuss issues and items on the agenda.”

10. … And you should keep it positive, too. The Americans demand it.

It all starts with a smile. “U.S. etiquette requires that you smile in each and every situation,” says the site Этикет США. “If you want to travel to America, be prepared to give a smile not only to friends and acquaintances, but also to all passers-by, in shops, to the staff at the hotel, police on the streets, etc.” Don’t whine about your problems or the troubles in your life, either: “Sharing in this country can only be positive emotions—sorrows and frustrations are impermissible. In the U.S. you only complain to acquaintances in the most extreme cases. Serious problems are for close friends and relatives only.”

This cheerfulness isn’t a put-on, the site notes. “Americans: they are a nation that truly feels happy. These people get used to smiling from the cradle onwards, so they do not pretend to be cheerful. The desire for a successful happy life is inculcated from childhood.”

11. Americans are very competitive …

According to an academic essay about the ethics of American etiquette at Bibliofond, “Americans love competition. They appreciate achievement records, and are constantly competing with each other. Although this behavior is natural for them, to us it may seem overbearing and intrusive. They are autonomous and independent. From early childhood, the Americans are accustomed to ‘stand on their own feet’ that is, rely only on themselves.”

A writer on the commercial export site Экспортеры России agrees: “A resident of this country will never complain and talk about their failures. Regardless of the situation, the American will always look confident, healthy, radiating success.”

12. … And are taught from a young age that they’re awesome.

If you’re a Russian visiting the U.S. and notice that Americans seem to have an overwhelming sense of superiority, know that that’s been ingrained in them since they were little, according to Экспортеры России: “The Americans have a strong sense of independence, self-reliance; they are able to compete and win anywhere, anytime. This is due to perceptions of citizens about the dominant position of the U.S. in the world, which is laid at an early age and is at the heart of the education system.”

13. Formality isn’t necessary.

Formality and overt classicism of any kind makes Americans uncomfortable. According to Экспортеры России, “The Americans, having a friendly nature, always seek to establish an informal atmosphere. So they prefer to communicate with people by first name, regardless of their age and position.”

Adds Bibliofond, “The Americans are straight people who appreciate honesty and candor, quickly move to the point of conversation and do not spend time on formalities. Americans do not like stiffness, and prefer comfortable, casual clothes. They refer to each other simply, informally, even if between the interlocutors there is a big difference in age and social position.”

14. Be very careful not to sound snooty.

Экспортеры России advises Russians visiting the U.S. to “Insert jokes into the conversations, it is considered a sign of good taste. And remember they speak American English. They consider London pronunciation an arrogant version of their language.”

15. Follow the Rules.

The travel site tonkosti knows that to many a Russian tourist, an American’s dedication to following rules will appear almost childish:

There is too much law-abiding in Americans. It makes them seem naïve to Russians. But it is due to the fact that almost everywhere is installed hidden cameras; in the shops, on the streets, in restaurants, hotels and so on. Hence, any offense cannot go unnoticed. It is better to stick to the letter of U.S. law than to escape from its clutches and reduce to zero the probability of re-visiting the American continent.

Walking against the light? Littering? Taking up two parking spaces? All against the rules. And you better make sure you recycle, too:

Modern cowboys do not smoke in public, i.e. restaurants, bars and other places where a zone is not provided for smokers. For smoking in the wrong place you could be fined, as well as for incorrect disposal of waste: for each type of waste (glass, plastic, paper) in the United States, there are separate boxes.

16. Don’t joke about being a terrorist. Americans will not laugh.

Tonkosti prepares would-be travelers for the ordeal of arriving at an American airport, which will likely involve a search of the traveler and his belongings and questions about terrorism:

You will be asked about the purpose of your visit to the United States (business travel, tourism, etc.), and—do not be surprised—airport employees may ask whether you have any relation to terrorist groups. In no case do you joke on the topic of terrorism—for the Americans it is a serious issue. If the person asking you questions on your arrival does not like your responses, you will be invited to the office of the security services at the airport. This is serious: you could be sent home, and never set foot on American soil.

17. Don’t call people ugly.

This should probably be filed under “commonsense things to avoid,” but Bibliofond warns travelers anyway:

At the table is better to avoid talking about politics and religion, as the United States is a country of Puritan values. In the straight-line American culture there is a taboo forbidding calling out the physical defects of another person. This is probably due to the constant desire of Americans to always be in great shape and look young.

Yeah. That’s probably the reason.

10 Things You May Not Know About ‘Pride and Prejudice’

filed under: books
Image credit: 
Jessica Hische for Barnes & Noble Leatherbound Classics Series

It’s a simple story: boy is rude to girl, girl dislikes boy. Boy proposes to girl and she refuses him. Later, she discovers that he’s stinking rich. Hijinks ensue. In the end, they are married in an ideal 19th-century wedding of both love and money. Today, over 200 years later, Pride and Prejudice remains Jane Austen’s most beloved novel.

1. Like her characters, Austen was rejected for not being rich enough.

Pride and Prejudice is about young women of gentile poverty trying to find good marriage matches. This issue must have been fresh on the young author’s mind when she wrote the book. At age 20, she had a flirtation with a young man named Tom Lefroy. Like a scene out of one of her novels, she flirted scandalously with him at a ball. “Imagine to yourself everything most profligate and shocking in the way of dancing and sitting down together,” she wrote to her sister Cassandra. “He is a very gentlemanlike, good-looking, pleasant young man, I assure you.” But Austen’s social status wasn’t high enough and Lefroy’s family separated the two lovebirds. Lefroy was soon engaged to a woman with a large fortune. Austen wrote her sister: “At length the day is come on which I am to flirt my last with Tom Lefroy … My tears flow as I write this, at this melancholy idea.” 

2. Mr. Darcy is extremely rich.

The characters in Pride and Prejudice constantly exclaim over Mr. Darcy’s $10,000 pounds a year, but how rich is that exactly? In 2013, The Telegraph calculated that adjusting for financial changes, a decent estimate might be 12 million pounds, or $18.7 million U.S. dollars a year. And that’s just interest on top of a much larger fortune. It’s no wonder Mrs. Bennet gushed about Elizabeth’s engagement—”How rich and how great you will be! What pin-money, what jewels, what carriages you will have!” Marrying Darcy would be like marrying a Rockefeller or a Vanderbilt. 

3. Lydia elopes to the Las Vegas of her day.

In the book, the Bennet family is almost ruined when Lydia elopes with the nefarious soldier George Wickham to Scotland. “I am going to Gretna Green,” Lydia writes her sister, “and if you cannot guess with who, I shall think you a simpleton.” Unlike England, Scotland allowed people under 21 to get married without parental consent, and without the same legal and religious bureaucracy. Gretna Green was the first town over the Scottish border. There, a young couple could be joined with “marriage by declaration,” which often occurred in a blacksmith shop.

4. Like Elizabeth and Jane, Austen was close to her sister.

In Pride and Prejudice, the relationship between the two sisters is central to the novel. In real life, Jane was very close to her sister Cassandra. They wrote each other almost every day when they were apart and would voluntarily share a bedroom, even when they could sleep separately. When Jane died, Cassandra wrote her niece: “She was the sun of my life, the gilder of every pleasure, the soother of every sorrow.” It’s no wonder that close sisters appear in so many of Austen’s novels. 

5. A publisher rejected the novel without even reading it.

Austen finished the book, then titled First Impressions, when she was 21 years old. In 1797, her father sent it to the publisher Thomas Cadell, writing that he had “a Manuscript Novel comprised in three Vols., about the length of Miss [Fanny] Burney’s Evelina.” He asked how much it would cost him to publish the book and what Cadell would pay for copyright. In response, Cadell scrawled “Declined by Return of Post” on the letter and sent it back with insulting speed. The novel languished for 14 years until, flush with the success of Sense and Sensibility, Austen revised the manuscript. It was published in 1813 when she was 37 years old. 

6. The title came from a Fanny Burney novel.

Austen probably got the title Pride and Prejudice from Cecilia by Fanny Burney, where the phrase is repeated several times—and in block capitals, no less. “The whole of this unfortunate business,” said Dr. Lyster, “has been the result of PRIDE and PREJUDICE. … If to PRIDE and PREJUDICE you owe your miseries, so wonderfully is good and evil balanced, that to PRIDE and PREJUDICE you will also owe their termination.” 

7. Pride and Prejudice was published anonymously.

Austen didn’t put her name on her novels, and would only say they were “By a Lady.” The title page of Pride and Prejudice said, “by the author of Sense and Sensibility.” It wasn’t until after her death that her brother revealed her name to the public. 

8. Austen worried the novel was too frivolous.

Because Pride and Prejudice humorously deals with women getting married, it’s often described as “chick lit,” a label some fans find reductionist. But Austen herself worried the book wasn’t serious enough. “The work is rather too light, and bright, and sparkling,” she wrote. “It wants shade; it wants to be stretched out here and there with a long chapter of sense, if it could be had.” Overall, though, Austen was “well satisfied enough” with the novel, especially with the character of Elizabeth. In another letter, she said, “I must confess that I think her as delightful a creature as ever appeared in print, and how I shall be able to tolerate those who do not like her at least I do not know.”  

9. She sold her copyright for 110 pounds—but wanted 150.

Austen sold the copyright for Pride and Prejudice to her publishers for 110 pounds, even though she said in a letter that she wanted 150 pounds. She chose this one-time payment, forfeiting any risk or reward connected to the future of the book. It was a bad gamble. The book was a best seller, and was on its third printing by 1817. It has been in print ever since. 

10. Pride and Prejudice has been adapted hundreds of times.

The adaptations of Pride and Prejudice seem endless (and sometimes bizarre). There have been at least 11 film and TV versions of the book, including the 1995 TV movie starring Colin Firth as a memorable Darcy. Other adaptations include Bridget Jones Diaries, the Bollywood movie Bride and Prejudice, the mystery novel Death Comes to Pemberley, and the web series “The Lizzie Bennet Diaries.” And Austen fever never stops—the movie version of Pride and Prejudice and Zombies is set to come out in February.

The Dynamic History of the Toy Chemistry Set

The chemistry set is an icon in the toy world. It’s ignited entire generations of aspiring scientists, and more than a few experiments gone awry, but it wasn’t an instant classic. In its 100 years on the scene, the toy chemistry set has seen its share of ups and downs on the long journey into the hearts and gift boxes of consumers.

The toy actually has purely practical roots. In the 1800s, portable kits containing chemicals, glassware, and various tools were sold for use in the academic world. Stores steadily cranked out the kits for students and professors until the distribution was largely halted by the outbreak of World War I (the kits were mostly assembled in England with chemicals supplied by Germany).

Meanwhile, two American brothers found inspiration in the chemistry kits and the rising popularity of a brand new toy, the Erector Set, which made its debut in 1913. John J. and Harold Mitchell Porter, owners of The Porter Chemical Company in Maryland, took a cue from the DIY spirit of the Erector Set and began manufacturing Chemcraft sets, similar to the English chemistry kits (they contained chemicals, a gas lamp, labware, and instructions), but marketed as a toy. Soon after the Porter Chemcraft set hit store shelves, the company found its first competitor. Alfred Carlton Gilbert, inventor of the Erector Set, caught wind of the brothers’ idea and, in 1920, decided to debut a chemistry set of his own.

By the ’30s, chemistry sets were being sold at major retailers like Woolworths, with advertisements emblazoned with “How to be a Boy Chemist!” and “Master the Mysteries of Modern Chemistry!” encouraging kids—mostly  boys—to explore the exciting world of science. Parents were on board, too. These chemistry sets were one of the first widely distributed toys whose advertisements appealed to fresh-from-the-Depression parents, playing on the belief that a chemistry set was not merely a toy, but a valuable first step toward a career in science.

Rosie Cook of the Chemical Heritage Foundation told Smithsonian magazine: “Coming out of the Depression, that was a message that would resonate with a lot of parents who wanted their children to not only have a job that would make them money but to have a career that was stable. And if they could make the world a better place along the way, then even better.”

Chemistry sets remained popular throughout the following decades, as new editions were released often to adapt to the changing attitudes toward different scientific disciplines. With the dawn of television came an entertainment-focused set that included a guide to putting on a magic show with chemistry. After World War II and the Manhattan Project, many new chemistry sets had a nuclear tilt. With the Space Race and moon landing around the corner, scientists were becoming a kind of superstar. The field of science was experiencing an unprecedented bump in coolness, and chemistry sets—finally giving kids access to science, actual science—became all the rage.

But the sets weren’t necessarily aimed at making science accessible for everyone—they were largely marketed toward white males. From advertisements to their packaging, the target market was clear.

Kristin Frederick-Frost, curator and collections manager at the Chemical Heritage Museum told WIRED, “The typical historical narrative goes that after the war and after Sputnik there’s this huge push to get more scientists in the field. If it was purely about mobilizing as many scientists as possible, the sets would have been made to be attractive to far more flavors of people than just white boys.”

It wasn’t just a narrow focus when it came to the intended user, the intended field was also zeroed in on defense and industrial use. Still, the kits did influence the lives of many. Robert F. Curl, Jr., recipient of the 1996 Nobel Prize in Chemistry, wrote in his Nobel autobiography: “When I was 9 years old, my parents gave me a chemistry set. Within a week, I had decided to become a chemist and never wavered from that choice.”

That golden era gave way to the ’70s and ’80s, when the public developed a growing mistrust of chemistry and its industries. In the years of Agent Orange, Three Mile Island, and Silent Spring, the American public’s shiny, futuristic perception of science was replaced with suspicion and a fear that chemistry could not only win wars for America, but wage war on its own citizens. Science was no longer exciting and cool, but scary, and chemistry sets declined in popularity. Chemistry sets now came with an emphasis on safety and many changes were inarguably for the better, as the kits of old were fraught with potential dangers. For example, glassblowing kits supplied children with a blowtorch, and some nuclear-focused kits of the ’50s contained radioactive uranium ore. A string of consumer protection laws in the 1970s did away with acid in chemistry sets, among several other limitations in the sets’ contents. Chemistry sets never quite reclaimed their mojo—for the most part, today’s sets are tamer, containing smaller amounts of chemicals, and, in some cases, none at all.

Some people are still championing the chemistry set’s cause, however. A recent Kickstarter campaign aimed at assembling and distributing old-school chemistry sets racked up more than 500 backers and nearly $150,000. The set is designed to match the one sold by the A.C. Gilbert company from the ’20s through the ’40s, chemicals and all. Taking a more futuristic approach, the Chemical Heritage Foundation released a free app called ChemCrafter, which enables iPad users to “create surprising color changes, encounter fire and smoke, release various gases, and shatter equipment,” all from the safety of the screen. It might not compare to the real thing, but these efforts might just be priming the old-school chemistry set for a comeback.

10 Mysteries of the Human Microbiome Revealed

Image credit:

You may think of your body as home to only one organism: you. But you actually host trillions of microbes, mainly bacteria, fungi and viruses, comprising their own individual microbiomes—ecosystems—too small to be seen with the naked eye.

Before you rush off to take a shower, consider that these living colonies in your body work in synergy with you to keep you healthy. Studying them can reveal imbalances in health, and offer avenues of treatment for a wide range of physical and mental health problems. Your microbiome is so unique to you, it could one day replace the fingerprint ID. And when artists interpret this amazing world, the results can be simply beautiful. Here are 10 mysteries revealed about the human microbiome.

1. YOU ARE MORE BACTERIA THAN HUMAN. 

Bacterial cells are so prolific in our bodies, that they outnumber our human cells 10 to 1. It’s only because they’re so microscopically tiny that we don’t notice their presence.

2. YOUR THROAT MICROBIOME MIGHT REVEAL IF YOU ARE LIKELY TO DEVELOP SCHIZOPHRENIA.

A recent study done at George Washington University found a notable difference in the throat microbiomes of schizophrenics as compared to healthy controls. In particular, they found high levels of lactic-acid bacteria and “an increased number of metabolic pathways related to metabolite transport systems including glutamate, and vitamin B12.” While there is much more research to be done, this information has potential applications for biomarkers that could detect and diagnose schizophrenia with a simple swab test, possibly before symptoms occur.

3. YOUR GUT MICROBIOME AFFECTS YOUR MOOD. 

Several studies have tested the effects of bacteria lactobacillus and bifidobacterium on mice and humans. In one study, mice fed these bacteria showed less anxiety or despair (measured by how willing mice are to rescue themselves when dropped into jars of water), which they compared to how mice behaved when given the anti-depressant drug Prozac. In another study, mice treated with the probiotics performed better on cognitive tests, including navigating mazes, and object recognition tests. And in the biggest known human study, a group of 25 healthy women ate yogurt with live bacteria every day for four weeks. Compared to the control group, the yogurt eaters had “calmer” reactions to images of facial expressions. Researchers are still trying to pinpoint how these good bacteria improve the mood; theories include activating compounds like serotonin, stimulating the vagus nerve, which releases the natural calming agent acetylcholine, and simply sending calming signals to the immune and nervous systems. Researchers hope that one day common psychiatric disorders could be treated with probiotics as well as drugs.

4. THE MICROBIOTA OF YOUR SKIN HELP PROTECT AGAINST INVADERS. 

The exterior surface of human skin is home to as many as 300 strains of bacteria. These microbes are intricately linked to your immune system, helping you defend against invading pathogens. While their intentions aren’t selfless—they are, after all, protecting their home—you receive multiple benefits: helping you heal wounds, control skin inflammation, and modulate T cells and interleukin-1, key compounds that fight infection, according to the National Human Genome Institute.

5. GREATER BACTERIAL BIODIVERSITY IS LINKED TO LOWER ALLERGIES.

If you’re looking for another reason to clean your house less often, more research points to allowing for more bacterial diversity in your home, and connects a reduction in bacterial biodiversity to an increase in allergies. Chemicals that clean floors and toilets also kill good bacteria—better to use “natural” agents like baking soda and vinegar, or to stress less over a slightly dirty floor, the dog sleeping on your bed, or using hand sanitizer for dirty hands. Other research suggests that reduced interaction with the natural world is also responsible for a rise in allergies. So go for a hike, and get dirty.

6. YOU HAVE BACTERIA DNA IN YOUR GENES. 

According to a study done by the University of Cambridge, as many as 145 of the genes in your human genome are bacteria genes that have used a process known as horizontal gene transfer to “jump” into human DNA over the course of our evolution.

7. YOUR DOMINANT HAND HOSTS DIFFERENT BACTERIA THAN YOUR NON-DOMINANT HAND.

Though you have approximately the same number of bacteria on each of your hands, research done at George Washington University has found that the colonies are different from hand to hand, suggesting that your dominant hand, with which you are likely to do more things, comes in contact with a different set of bacteria than the other hand.

8. BACTERIA HAVE GENDER PREFERENCES.

Men always take heat for being dirtier than women, but it might be true, in a way. At the very least, the bacteria Corynebacterium—usually found in the armpit and responsible for the pungent odor—prefers male chemistry. It’s 80 percent more abundant on male skin than on female skin, according to a study published in the journal PNAS.  But Enterobacteriales is 400 percent more abundant on women, and Lactobacillaceae (primarily found in the mouth and the vagina) is 340 percent more abundant. In general, the palms of women were found to have greater bacterial diversity than the palms of men. Some explanations for this diversity may have to do with the slightly different Ph balance between male and female skin, differences in sweat and sebum (oil) production, and the frequency of moisturizer or cosmetics use.

9. YOUR BELLY BUTTON HAS ITS OWN MICROBIOME.

There are more than 1400 strains of bacteria that call your “inny” home, with as many as 662 of those not previously identified by science until the Belly Button Biodiversity Project analyzed them. And in case you were wondering, “outies” are the same.

10. YOUR FIRST MICROBIOME CONTACT WAS IN UTERO. 

For years, science considered the uterus of a pregnant woman a sterile environment, but new research published in Science Translational Medicine revealed that placentas have a unique microbiome that is different from any other part of the body (though most similar to the microbiome of the mouth). Contact with their mothers’ placentas, and the umbilical cord that attaches them, offers babies their first exposure to the bacteria that will soon colonize and support their own small bodies. Understanding this particular microbiome may also help researchers learn more to treat in utero infections and preterm births.
