This Math Problem for 8-Year-Olds Left Parents Stumped

Life for grade-schoolers has changed a lot in just a few decades. While students growing up in the pre-digital age had to suffer through insanely difficult homework in silence, kids (and their parents) today can share their frustrations on the internet.

According to Over Sixty, the latest assignment to go viral comes from the parenting message board Mumsnet. After posting their 8-year-old child's math homework on a forum, user lucysmam quickly saw that the other parents were just as baffled by it. Here's the problem:

“On the coast there are three lighthouses. The first light shines for 3 seconds, then it is off for 3 seconds. The second light shines for 4 seconds, then it is off for 4 seconds. The third light shines for 5 seconds, then it is off for 5 seconds. All three lights have just come on together.

When is the first time that all three of the lights will be off together?

When is the next time that all three lights will come on at exactly the same moment?”

Give up? The answer the parents came up with was 6 seconds for the first question and 120 seconds for the second one. The question becomes easier when you think of the lighthouses this way: The first one lights up every 6 seconds, the second one lights up every 8 seconds, and the third one lights up every 10 seconds. To calculate when all the lights will coincide, you need to find the lowest number divisible by six, eight, and 10, which comes out to 120.

When it comes to head-scratching elementary school lessons, this problem is just the start. If this viral problem is any indication, 6-year-olds have it even worse than 8-year-olds.

California's Wizarding World of Harry Potter Has Issued a Casting Call for Performers

Attention aspiring wizards and witches: Your Hogwarts letter has finally arrived in the form of a casting call. According to Fansided, The Wizarding World of Harry Potter at Universal Studios Hollywood is seeking performers to enchant park guests.

In addition to thrill rides, high-tech wands, and magical meals, Harry Potter World in Los Angeles, California, relies on a staff of magical cast members to bring the universe of the books and films to life. Universal Studios' new wizards should be "energetic dancers and talented performers" who are at least 18 years old. Like Harry and his Hogwarts crew, the characters at Harry Potter World hail from the UK, and new hires must be able to "speak in a specified British dialect for sustained periods of time."

When the original Wizarding World of Harry Potter opened in Orlando, Florida, in 2010, it dazzled fans with its level of detail. The park features interactive Easter eggs, recreations of props from the movies, and butterbeer approved by J.K. Rowling herself. Any actors joining the cast will likely be held to high standards when it comes to committing to the theme.

The casting call is for ongoing seasonal roles, with training taking place and February and March of this year for applicants who make the cut. Check out the full posting to learn more and apply.

David Lynch's Amazon T-Shirt Shop is as Surreal as You'd Expect It to Be

David Lynch, the celebrated director behind baffling-but-brilliant films like Eraserhead, Blue Velvet, Mulholland Drive, and Twin Peaks, is now selling his equally surreal T-shirts on Amazon.

Each shirt bears an image of one of Lynch’s paintings or photographs with an accompanying title. Some of his designs are more straightforward (the shirts labeled “House” and “Whale” feature drawings of a house and a whale, respectively), while others are obscure (the shirt called “Chicken Head Tears” features a disturbing sculpture of a semi-human face).

This isn’t the first time Lynch—who is celebrating his 73rd birthday today—has ventured into pursuits outside of filmmaking. Previously, he has sold coffee, designed furniture, produced music, hosted daily weather reports, and published a book about his experience with transcendental meditation. Art, in fact, falls a little closer to Lynch’s roots; the filmmaker trained at the Pennsylvania Academy of the Fine Arts before making his mark in Hollywood.

Lynch’s Amazon store, known as Studio: David Lynch, currently sells more than 40 T-shirts and hoodies, ranging in size from small to triple XL, with prices starting at $26. As for our own feelings on the collection, we think they’re best reflected by this T-shirt named “Honestly, I’m Sort of Confused.”
