Calling all problem-solvers and puzzle masters: A library in Bloomington, Indiana, is home to the world's only public display of mechanical puzzles. The Jerry Slocum Mechanical Puzzle Collection can be found at Indiana University’s Lilly Library, which also houses rare books and manuscripts, including Queen Elizabeth I's Great Seal and an early printed copy of "The Star Spangled Banner."

The collection is named after Jerry Slocum, a Chicago-area native who started donating his personal collection of puzzles to the library in 2006. The library now has over 34,000 mechanical puzzles, which, unlike jigsaw and crossword puzzles, tend to feature interconnected pieces that must be physically manipulated in order to solve the problem. There are exceptions, though. One subset of mechanical puzzle called an “impossible puzzle” requires no movement at all; instead, the player must figure out how the puzzle was built.

An online database of the collection lets users search by the puzzle’s date of creation, designer, maker, or classification. The oldest item is a 15th-century Khmer iron lock from Cambodia that contains trick locks and keys. But according to Indiana State Library, puzzles weren’t always created for their entertainment value. In the second century BCE, for example, Romano-Celtic puzzle padlocks were used strictly for security purposes. It wasn’t until the 19th century that the puzzle emerged as a fun pastime.

In a YouTube video uploaded by the Indiana Daily Student, the collection’s curator, Andrew Rhoda, tries his hand at the “Gear Cube Extreme,” which looks like a Rubik’s Cube on steroids. “The puzzle is complicated by the addition of gears that move at half-turns while the rest of the puzzle moves at quarter-turns,” Rhoda says in the video.

Unless a particular piece is being conserved, visitors are encouraged to grab a puzzle and start playing inside the library’s reading room. “Mechanical puzzles are really hard to understand if you see them behind glass,” Rhoda told the student news outlet in 2017. “You can sort of understand what is going on with a mechanical puzzle if you look at it behind glass and read an exhibit label. But to really understand the idea behind a puzzle, you have to handle it. You have to play with it. You have to try to solve it.”

A Handy Map of All the Royal Residences in the UK

Somewhere along the way, you probably learned that Buckingham Palace is home to the ruler of the United Kingdom and many unflinching, fancily clad guards. And, if you watch The Crown or keep a close eye on royal family news, you might recognize the names of other estates like Windsor Castle and Kensington Palace.

But what about Gatcombe Park, Llwynywermod, or any of the other royal residences? To fill in the gaps of your knowledge, UK-based money-lending site QuickQuid created a map and corresponding illustrations of all 20 properties, and compiled the need-to-know details about each place.

Queen Elizabeth II and Prince Philip kept eight estates for themselves, and divvied up the rest among their children and grandchildren, some of whom have purchased their own properties, too. Though Buckingham Palace is still considered the official residence of the Queen, she now splits most of her time between Windsor Castle and other holiday homes like Balmoral Castle in Scotland and Sandringham House, which Prince Philip is responsible for maintaining.

Windsor shares its grounds with two other properties: Prince Harry and Meghan Markle’s home, Frogmore House, and the Royal Lodge, where Prince Andrew (the Queen’s second youngest child) lives.

Southwest of Windsor is Highgrove House, Prince Charles’s official family home with wife Camilla, Duchess of Cornwall. They also own Birkhall in Scotland, Clarence House in London, Tamarisk House on the Isles of Scilly, and the aforementioned Llwynywermod in Wales. Much like the Queen herself does, Charles and Camilla basically have a different house for each region they visit.

In 2011, the Queen gave Anmer Hall—which is on the grounds of Sandringham House—to Prince William and Kate Middleton as a wedding gift, but they’ve recently relocated to Kensington Palace so Prince George could attend school in London.

Queen Elizabeth and Prince Philip’s only daughter, Anne, resides in Gatcombe Park with her daughter, Zara Tindall. Anne also owns St. James’s Palace in London, where her niece (Princess Beatrice of York) and her mother’s cousin (Princess Alexandra) sometimes live.

Lastly there's Edward, Elizabeth and Philip's youngest son, who lives with his wife in Bagshot Park, which architectural historian Nikolaus Pevsner called “bad, purposeless, [and] ugly.”

If you’re feeling particularly cramped in your tiny one-bedroom apartment (or even regular-sized house) after reading about the royal family’s overabundance of real estate, take solace in the knowledge that at least you’ll never have to follow their strict fashion rules.

A Book Fair for Grown-Ups Is Coming to New York

Amid all the prepubescent drama and uncertainty of elementary school was one glimmering spot of hope and happiness: the Scholastic Book Fair. Getting to take just a few minutes out of your regular school day to wander the temporary bookshelves seemed about as enchanting as walking through the wardrobe into Narnia.

For folks who’ve been chasing that particular brand of ecstasy well into their adult lives, we have some big news. Next month, Penguin Random House is hosting a book fair for grown-ups. The Pop Insider reports that the event will take place at Lightbox in New York on Saturday, November 23, and you must be at least 21 years old to attend.

It’s not intended to be an exact replica of the book fair from your own school days, but rather a full-fledged recreation of your entire grade-school experience. The electronic invitation promises pop culture trivia, Mad Libs, an “awkward school photo booth,” spin art, snap bracelets, Mr. Sketch markers, cubbies, and “severe middle school flashbacks.”

There will also, of course, be books for sale, though it’s not clear if the inventory will include throwback series like Junie B. Jones and The Magic Treehouse, or just books for adults.

In addition to tsunami-sized waves of nostalgia, the event will feature appearances from some of Penguin Random House’s beloved authors. The list hasn’t been revealed in full, but Viking Books, an imprint of Penguin Random House, tweeted that its author John Hodgman will be there to promote his new book, Medallion Status.

Tickets are $25 for a one-hour time slot, or you can pay $50 to stay for the whole five hours. And your afternoon of embracing your inner kid will benefit actual kids—Penguin Random House will donate a portion of ticket sales to Read Ahead, a non-profit that uses reading to help students learn life-long social and emotional skills.

While the Scholastic Book Fair is still going strong in schools today, the same can’t be said for card catalogs, dodgeball, or these other things.
