Here's How You Should Actually Tie Your Shoes
Take a look down. Chances are, you're looking at a lopsided tangle of bad technique.
Take a look down. Notice anything wrong? Well, unless you're some beach-bound denizen wearing flip-flops, you're more than likely wearing shoes with laces. And it appears that the vast majority of the human race has been tying their shoes wrong the whole time.
Yes, you've (probably) been tying your shoes wrong your whole life.
The "bunny ears" method — the popular knot-tying technique that involves a pretty gripping story about a bunny running around a tree and back into its hole — is one of the worst knots to tie if you're worried about longevity. The bunny ears knot (also known as the Granny Knot) is dubious thanks to its weak central knot, which comes undone due to repeated ground impact from the foot combined with the motion it takes to put one foot in front of the other. This motion often leads to one of the laces rubbing off against the other until one of them comes loose, resulting in what the researchers have called 'catastrophic knot failure' (and is also a sweet band name).
What you should be doing is the (drum roll please) Square Knot (hold for applause), or what is sometimes referred to as the Reef Knot. It is a knot of such magnificence that it has been used by sailors for centuries and is, according to a knot theorist Professor Colin C. Adams, the "way to go."
So now, dear readers, you know that all those times you've looked down at your foot and thought, "Dammit now I have to bend over in front of strangers in public," have actually been your knot's fault and (k)not your own.
How a cataclysm worse than what killed the dinosaurs destroyed 90 percent of all life on Earth.
While the demise of the dinosaurs gets more attention as far as mass extinctions go, an even more disastrous event called "the Great Dying” or the “End-Permian Extinction” happened on Earth prior to that. Now scientists discovered how this cataclysm, which took place about 250 million years ago, managed to kill off more than 90 percent of all life on the planet.
A new study discovers the “liking gap” — the difference between how we view others we’re meeting for the first time, and the way we think they’re seeing us.
We tend to be defensive socially. When we meet new people, we’re often concerned with how we’re coming off. Our anxiety causes us to be so concerned with the impression we’re creating that we fail to notice that the same is true of the other person as well. A new study led by Erica J. Boothby, published on September 5 in Psychological Science, reveals how people tend to like us more in first encounters than we’d ever suspect.
Using advanced laser technology, scientists at NASA will track global changes in ice with greater accuracy.
Leaving from Vandenberg Air Force base in California this coming Saturday, at 8:46 a.m. ET, the Ice, Cloud, and Land Elevation Satellite-2 — or, the "ICESat-2" — is perched atop a United Launch Alliance Delta II rocket, and when it assumes its orbit, it will study ice layers at Earth's poles, using its only payload, the Advance Topographic Laser Altimeter System (ATLAS).
