For years, it was thought that a piece of paper could not be folded in half more than seven times. Back in 2002 though, then-high school student Britney Gallivan folded a piece 12 times. And later, Mythbusters tackled the same issue. Now, students the St. Marks School, a Massachusetts prep school, completed 13 folds. From New Scientist:
Based on the thickness of a sheet of paper, a formula can be used to calculate the minimum length needed to fold it a given number of times. Paper roughly doubles in size with each fold and the sides become more rounded, making it harder and harder to bend. Wrinkles also have a significant impact, making the formula difficult to follow in practice. In addition, no single roll is long enough to fold thirteen times, requiring the group to tape together numerous rolls of industrial toilet paper 1.2 kilometers long.

The forced transition from analog to digital TV signals was probably met with relative indifference from people with Netflix subscriptions and the “I don’t even own a TV” snoots. But anyone living in the vast swaths of the country that don’t have guaranteed high-speed internet, broadcast TV is a perfectly valid (and 100% free) way […]
