Can You Figure Out This Math Problem Intended for 7-Year-Olds?

At one time or another, most adults have been roped into helping a grade-schooler with his or her homework. Usually, it’s a bit of an ego boost to have a pre-teen look at you like some sort of modern-day Euclid when you start dropping terms like “equilateral triangle.” But one particular math problem left six- and seven-year-old students in the UK stumped—and their parents scratching their heads.

The math problem, which you can see below, was originally posted to Twitter by Louise Bloxham, a mom in England who was shocked that the question was on her second-grader’s standard assessment test.

The post quickly went viral, with adults around the world weighing in on the unnecessary pressure that standardized testing puts on kids—and many admitting that they themselves couldn’t figure out the answer. (Which, if you haven’t figured it out, is 65.)

At One Swiss University, You Can Now Major in Yodeling

Switzerland’s yodeling tradition began in remote Alpine meadows, but now, new generations of students can opt to learn the folk art in a college classroom. The Lucerne University of Applied Sciences and Arts has become the nation’s first university to offer bachelor’s and master’s degrees in yodeling, according to The Local.

Lucerne University has offered folk music degrees since 2012, but it took the department several years to find a qualified yodeling teacher. They finally settled on Nadja Räss, a famous Swiss yodeler who runs her own academy in Zurich. Under her tutelage, three to four incoming students will learn to yodel-ay-ee-oo while also taking classes in musical history, theory, and business.

Yodeling is today performed on stages, but it was once used as a method of communication among Alpine shepherds. By alternating falsetto notes with natural singing tones, they were able to communicate across mountains and round up livestock. These lyric-less cries developed into songs by the 19th century.

Today, the technique is no longer just for shepherds. Yodeling is undergoing a musical revival and occasionally enjoying five minutes of YouTube fame.

In 2014, Swiss officials announced that they intended to submit Alpine yodeling for consideration to UNESCO’s World Heritage list, along with traditions like mechanical watchmaking, typography, and managing the risk of avalanches, according to The Telegraph. Due to current guidelines, countries can only supply one entry each year. At least Switzerland’s yodelers will now have new opportunities to study their craft as they await their chance to shine on the international stage.

Design Firm Envisions the Driverless School Bus of the Future

Engineers have already designed vehicles capable of shuttling pizzas, packages, and public transit passengers without a driver present. But few have considered how this technology can be used to transport our most precious cargo: kids. Though most parents would be hesitant to send their children on a bus with no one in the driver's seat, one design firm believes autonomous vehicle technology can change their rides for the better. Their new conceptual project, called Hannah, illustrates their ideas for the future of school bus travel.

As Co.Design reports, Seattle-based design firm Teague tackled both the practical challenges and the social hurdles when designing their driverless school bus. Instead of large buses filled with dozens of kids, each Hannah vehicle is designed to hold a maximum of six passengers at a time. This offers two benefits: One, fewer kids on the route means the bus can afford to pick up each student at his or her doorstep rather than a designated bus stop. Facial recognition software would ensure every child is accounted for and that no unwanted passengers can gain access.

The second benefit is that a smaller number of passengers could help prevent bullying onboard. Karin Frey, a University of Washington sociologist who consulted with the team, says that larger groups of students are more likely to form toxic social hierarchies on a school bus. The six seats inside Hannah, which face each other cafeteria table-style, would theoretically place kids on equal footing.

Another way Hannah can foster a friendlier school bus atmosphere is inclusive design. Instead of assigning students with disabilities to separate cars, everyone can board Hannah regardless of their abilities. The vehicle drives low to the ground and extends a ramp to the road when dropping off passengers. This makes the boarding and drop-off process the same for everyone.

While the autonomous vehicles lack human supervisors, the buses can make up for this in other ways. Hannah can drive both backwards and forwards and let out children on either side of the car (hence the palindromic name). And when the bus isn’t ferrying kids to school, it can earn money for the district by acting as a delivery truck.

Still, it may be a while before you see Hannah zipping down your road: Devin Liddel, the project’s head designer, says it could take at least five years after driverless cars go mainstream for autonomous school buses to start appearing. All the regulations that come with anything involving public schools would likely prevent them from showing up any sooner. And when they do arrive, Teague suspects that major tech corporations could be the ones to finally clear the path.

"Could Amazon or Lyft—while deploying a future of roving, community-centric delivery vehicles—take over the largest form of mass transit in the United States as a sort of side gig?" the firm's website reads. "Hannah is an initial answer, a prototype from the future, to these questions."
