Established in 1800 in Washington, D.C., the Library of Congress is the world’s largest library. Their Congressional Research Service helps members of Congress conduct research on U.S. laws and policies, but the public is also free to visit and browse items from the library’s impressive collection. The institution employs thousands of people, from curators and archivists to IT specialists, but only one person—the Librarian of Congress—is appointed by the president to oversee the entire operation. Today, Dr. Carla Hayden serves as the 14th (and first female and African-American) Librarian of Congress. Mental Floss spoke to Hayden to learn the ins and outs of her job as Librarian-in-Chief, from her work defending democracy to her love of the library’s spinach smoothies.

1. HER OFFICE VIEW IS KILLER.

Before becoming Librarian of Congress in 2016, Hayden served as the CEO of Baltimore’s Enoch Pratt Free Library, the president of the American Library Association, and deputy commissioner and chief librarian of the Chicago Public Library. But her current gig arguably has the biggest perks, including the view from her office window.

Located on Capitol Hill, the Library of Congress comprises three structures, known as the Jefferson, Madison, and Adams Buildings. “The Madison Building [is] where my day to day office is,” Hayden tells Mental Floss. “I’m facing the magnificent Jefferson building … and immediately to the left is the U.S. Capitol,” she says. “It really makes a wonderful visual synergy of those institutions.”

2. WATCHING MOVIES IS PART OF HER JOB DESCRIPTION.

Although books and manuscripts are essential to the library, films are important, too, as documents that reflect American society, culture, and history. Each year, the National Film Preservation Board makes recommendations to Hayden for the 25 films that should be added to the National Film Registry, and she and members of the Film Board then make the final choices.

The library even has a separate building in Culpeper, Virginia—the Packard Campus—devoted to preserving culturally significant films, TV and radio shows, and sound recordings. “I got a chance to visit and spend the day there,” Hayden says. “I was able to see the different rooms that are used to preserve audio recordings and films. When I was there they were looking at Jerry Lewis’s home movies.”

The Packard Campus even hosts film showings. Hayden explains: “It has wonderful public programs in a magnificent film theater that is state-of-the-art with a pipe organ and even a popcorn machine.”

3. SHE LOVES EXPERTS.

Hayden’s duties require her to oversee the library’s massive collection—as well as its 3149 full-time staff members. “The Librarian of Congress works with a variety of people who are specialists in so many fields,” Hayden explains. “You have people who speak several languages, who are specialists in French literature or Lithuanian history. There’s such a variety of expertise and talent at the library.” Hayden adds that her favorite part of her job is working with the expert staff members. “Every time I interact with them, I learn a lot. You’re almost a professional student,” she says.

4. SHE READS ON HER COMMUTE.

Because Hayden lives in Baltimore, Maryland and commutes to D.C. for work, she sometimes uses her transit time for one of her favorite activities—reading. (Depending on her schedule and what’s happening at work, Hayden either drives or takes the train.) “Right now on the train, which I’ve been experimenting with even more, it [takes] an hour. And that’s a good time to read and reflect, and on the way home, relax,” she says.

Although Hayden says that she doesn’t have as much time as she’d like to devote to reading for pleasure, she admits that the line between reading for pleasure and reading for work can overlap. “Some of the reading that I’m doing for work—like more about the founding fathers and mothers—that is actually interesting [to me] because I’m a history and political science major from undergraduate,” she says. A few of Hayden’s favorite books include Bright April, a children’s book by Marguerite de Angeli, and The Historian As Detective by Robin W. Winks.

5. SHE APPOINTS THE U.S. POET LAUREATE AND OVERSEES COPYRIGHT.

Hayden’s duties are multifaceted: She appoints the U.S. Poet Laureate, helps choose the Gershwin Prize for Popular Song, and appoints the Register of the U.S. Copyright Office (located in the Library’s Madison Building), among other responsibilities. How does she choose the recipients of such lofty titles? By consulting with experts, of course. “The library is very fortunate to have wonderful advisory committees and people who help with different suggestions for [Poet Laureate and Gershwin Prize] selections,” she says.

As for copyright, Hayden says: “The Register is responsible for managing the process of copyright and also for advising Congress on the legal aspects of copyright.” Hayden also makes sure the Copyright Office has the resources it needs so that it is run efficiently. “The Librarian does not advise on the legal aspects—that’s the expertise of the Register,” she says.

6. SHE WANTS TO MAKE BEING A LIBRARIAN COOL.

In an interview with CBS This Morning in 2016, Hayden explained one of her goals as Librarian of Congress: “We want to make sure that history is fun and people see the [librarian] profession as something that is desirable.”

Part of making history fun is making it accessible to millions of people, whether they’re able to visit the library or not. One way to modernize the library is to use social media to connect with people around the U.S.—and world. “I am the first Librarian [of Congress] to tweet, and since my swearing in I have 10,000 followers,” she told CBS. Today, she has more than 45,000 followers.

7. SHE LOVED HER SWEARING-IN CEREMONY.

In September 2016, Supreme Court Chief Justice John Roberts delivered an oath to Hayden as Speaker Paul Ryan and Hayden's mother stood beside her. As Hayden explains, the support from her soon-to-be staff is what stands out for her about her swearing-in ceremony: “There were so many staff members who were there in the mezzanine section, in particular, and they were clapping and cheering and had a welcome sign. That was such a wonderful feeling to know that the staff members were enthusiastic,” she says. Hayden fondly recalls meeting approximately 400 staff members who came to her ceremony. “It was really something. That was a big hearty welcome. I was really touched.”

8. SHE ENJOYS THE LIBRARY’S SPINACH SMOOTHIES.

People think of the library as a scholarly place, with its reading rooms, exhibits, and guided tours. But librarians and library visitors have to eat, too. The library offers several dining options, including the Madison Café, Jefferson Coffee Shop, and Madison Snack Bar (with a Subway and Dunkin Donuts). And if you visit the library and stop to have lunch, you might just run into the Librarian-in-Chief. “I love the Madison Café,” Hayden says. “There’s a Korean bowl that I’m pretty partial to, and now I’m doing the spinach smoothie. The variety is really good and you can bump into a Congressperson or staffer. It’s a nice cafeteria.”

9. HER JOB HELPS HER DEFEND DEMOCRACY.

In a 2016 interview with PBS NewsHour, Hayden explained that because libraries promote literacy and let everyone access information, they affirm freedom, democracy, and equality. “Libraries are a cornerstone of democracy—where information is free and equally available to everyone,” Hayden has said.

The Library of Congress also strives to be a role model for all libraries, serving as an example of how libraries can bolster freedom of thought, bring books into the digital age, and help people access valuable information.“Health information is just about the number one thing that people go into public libraries and connect to public libraries for. They’re also looking for information about things that can make their lives better,” Hayden tells PBS. “It’s a great equalizer.”

12 Secrets of Roller Coaster Designers

Back in the early 20th century, engineers attempting to push the limits of roller coaster thrills subjected riders to risky upside-down turns and bloody noses. A century later, coaster designers rely on computer software, physics, and psychology to push the limits of the roughly 5000 rides in operation worldwide. To get a sense of what their job entails, Mental Floss spoke with several roller coaster specialists about everything from testing rides with water-filled dummies to how something as simple as paint can influence a coaster experience. Here’s what we learned.

1. Getting strapped in might be the most exciting part of the roller coaster ride.

Known as a “thrill engineer,” UK-based Brendan Walker consults with coaster manufacturers and parks on the psychology of riding the rails. In his experience, riders getting secured into their seats are at the peak of their excitement—even more so than during the ride itself. “The moment the lap bar is being locked down and you have that feeling of things being inescapable, that you have to suffer the effects of the ride, is the highest moment of arousal,” Walker says. “The actual ride might only achieve 80 percent of that excitement.”

2. Designers test roller coasters with water-filled dummies.

Bill Kitchen, founder of U.S. Thrill Rides, says it can take anywhere from two to five years for a coaster to go from idea to execution. Part of that process is devoted to the logistics of securing patents and permits for local site construction—the rest is extensive safety testing. “We’re subject to ASTM [American Society for Testing Materials] standards,” Kitchen says. “It covers every aspect of coasters. The rides are tested with what we call water dummies, or sometimes sandbags.”

The inanimate patrons allow designers to figure out how a coaster will react to the constant use and rider weight of a highly trafficked ride. The water dummies—which look a bit like crash test dummies, but filled with water—can be emptied or filled to simulate different weight capacities. Designers also sometimes use the kind of crash-test dummies found in the auto industry to observe any potential issues prior to actual humans climbing aboard.

3. Every foot of roller coaster track costs a lot of money.

There is absolutely nothing random about the length of a coaster’s track. In addition to designing a ride based on the topography of a park site, designers take into account exactly how much space they’ll need to terrorize you and not an inch more. When England’s Alton Towers park was preparing to build a ride named TH13TEEN for a 2010 opening, they asked Walker exactly how much of a drop was needed to scare someone in the dark. “It was a practical question,” Walker says. “For every extra foot of steelwork, it would have cost them £30,000 [roughly $40,000].”

4. Rollercoaster Tycoon brought a lot of people into the business.

The popular PC game, first released in 1999, allowed users to methodically construct their own amusement parks, including the rides. As a proving ground for aspiring engineers and designers, it worked pretty well. Jeff Pike, President of Skyline Attractions, says he’s seen several people grow passionate about the industry as a direct result of the game. “I remember when the game first got popular, I would go to trade shows and there would be kids looking to get into it using screen shots of rides they designed. The game definitely brought a lot of people into the fold.”

5. Paint makes a big difference in coaster speed.

For all of their high-tech design—the software, fabrication, and precise measures of energy—a good coaster ride can often come down to whether it’s got too much paint on it. “The one thing that will slow down a steel coaster is a build-up of paint on the track rails,” Pike says. “It softens where the wheel is rolling and hitting the track, which increases the drag.” A good, worn-in track will have gray or silver streaks where the wheel has worn down the paint, making it move more quickly.

6. A roller coaster’s skyline is key.

Brian Morrow, former Corporate Vice President for Theme Park Experience at SeaWorld Parks and Entertainment, says that the looming curvature of coasters spotted as guests drive toward and enter the park is very purposeful. “It’s like a movie trailer in that we want you to see some iconic coaster elements, but not the whole thing,” he says. “You approach it with anticipation.”

7. Some coasters arrive as giant model kits.

Whether a coaster’s theme or design comes first is largely left up to the end user—the amusement park. But for some rides, manufacturers are able to offer pre-fabricated constructions that designers can treat like the world’s biggest Erector Set. “Sometimes I work on rides that have already been built,” Walker says. “They’re produced by a company and presented almost like a kit with parts, like a model train set. There’s a curve here, a straight bit here, and you can pick your own layout depending on the lay of the land.”

8. Wooden roller coasters are weather-sensitive.

If you’ve ever been on a wooden coaster that seems a little shaky from one trip to the next, check the forecast: It might be because of the weather. Pike says that humidity and other factors can shrink the wood, affecting how bolts fit and leading to a slightly shakier experience. “The structure itself can flex back and forth,” he says. It’s still perfectly safe—it just takes more maintenance to make sure the wood and fasteners are in proper operating condition. A well-cared-for wooden coaster, Pike says, can usually outlast a steel model.

9. The time of day can affect the coaster experience.

“A coaster running in the morning could run slower when cooler,” Morrow says. “The wheels are not as warm, the bearings are warming up. That could be different by 2 p.m., with a slicked-up wheel chassis.” Coasters experiencing their first-ever test runs can also be slightly unpredictable, according to Pike. "Those first trial runs [during the testing phase] can be slow because everything is just so tight," he says. "A lot of coasters don't even make it around the track. It's not a failure. It's just super-slow."

10. Roller coaster designs can come from unusual places—like Jay Leno’s chin.

The twisting, undulating tracks of coasters can often be the result of necessity: Pike says that trees, underground piping, and available real estate all inform designers when it comes to placing a ride in a specific park. But when they have more freedom, coasters can sometimes take on the distinctive shape of whatever happens to be around the designers at the time of conception. “We had a giant piece of land in Holland that just had no constraints, and we were sitting around talking," Pike says. “And we started talking about Jay Leno’s chin.” The ride was a “loose” representation of the comedian's jaw, but “it is there.”

11. Roller coaster riders double as performers.

For Walker, the best advertising for a coaster is having spectators watch riders de-board after an exhilarating experience. “It’s all about that emotion,” he says. “A spectator basically asks, ‘What’s making them so aroused? What’s giving them such pleasure?’ The line for the ride is the audience. Imagining yourself on the structure becomes a very powerful thing."

12. The future of coasters is vertical.

Biggest, fastest, longest—coasters are running out of superlatives. Because rides can only be designed with so many drips, rolls, or G forces, some companies are looking to the sky for their next big idea. Kitchen has been overseeing design of the Polercoaster for years: It’s a sprawling, skyscraper-esque ride that uses electromagnetic propulsion to carry riders upwards instead of across horizontal tracks. “We want to put it in places where land is very expensive, like the Vegas strip,” he says. “You can only do that if it takes up a lot less space.” The project is set to exceed the 456 feet of the current tallest ride, Kingda Ka at Six Flags in New Jersey. “It’ll be the world’s tallest—and hopefully the most fun.”

This list first ran in 2017.

Here's Why You Should Always Tip Your Delivery Driver With Cash

In our microchip- and app-happy society, we’ve all but abandoned paying for things in cold, hard cash. And while that’s almost definitely more efficient for you, it could be costing your delivery driver their tip, Lifehacker reports.

Some food delivery services guarantee a minimum payment for their drivers, which seems like a good thing on the surface. Basically, the company will pay the driver the agreed-upon base payment, even if it’s a slow shift and they don’t actually reach that amount in delivery charges. But it also means that everything they earn, including tip, is going toward that base payment. In other words, your tip is saving the company from having to pay more of the base payment.

The best way to ensure that your tip goes into your driver’s pocket is to give them a tip that they can literally put in their pocket—namely, cash. If you don’t have cash around or like to keep your finances digital for credit card rewards or tracking purposes, you should choose a delivery service that promises to pay their employees the full amount of whatever they earn, including tip.

Take a look at Lifehacker’s handy breakdown below to find out which delivery services you can trust with your tips, and read the policy details for each service here.
