A Story Of Mixed Emoticons

Emoticons can express more than you think.

I’ll admit it. This 3:17 talk from the performance poet Rives won’t teach you very much, unless you’re a creative emoticon user, in which case it may provide some inspiration. But this sweet little tale of a chance encounter will put a smile on your face and make you glad you took the time to watch.

How To Tie Your Shoes

How To Tie Your Shoes

You’ve been tying your shoes wrong your whole life.

No, I’m not kidding. The way we all learned to tie our shoes as children leads to a weak knot, whereas one small change creates a knot that both holds together better and looks a lot better, as Terry Moore, director of the Radius Foundation demonstrates. Even if you favor slip-ons, it’s worth taking three minutes to see how.

Watching A Thunderstorm Live

Watching A Thunderstorm Live

A stationary supercell in South Dakota recently offered a stunning example, letting photographer Nicolaus Wegner capture its growth in a time-lapse video (above) without having to chase it — or vice versa. Its lack of mobility may have made it slightly less dangerous for Wegner, aside from the threat of lightning, but it also gave him a rare opportunity to record a supercell from start to finish.

Filmed June 1, the video opens with footage of the young storm vacuuming up warm, moist air from below to fuel its growth. While supercells are often nudged along by wind, this one seems anchored in place as its rotating air mass — known as a mesocyclone — mushrooms into a monster. It steadily tightens into more intricate and imposing shapes, and by the 1:00 point it’s like a wispy alien spaceship glowing eerily from within. As with most nature videos of this quality, it’s best watched in HD and full-screen modes with the music turned up full.

Aside from its obvious beauty, what makes a supercell super? The rotation starts with wind shear, slicing air into layers and forming a horizontal axis that’s then tilted vertically by updrafts. These updrafts exceed 100 mph in some cases, helping supercells and multicells grow 10 to 100 times more energetic than a typical thunderstorm, which can already release as much energy as a 20-kiloton nuclear explosion.
