The Importance of Relative Velocity in Military Aviation

Recently, a Dutch F-16 managed to shoot itself with its own gun during maneuvers.

The rounds have a muzzle velocity of 3,450 feet per second (1050 meters per second). That is speed boosted initially by the aircraft itself, but atmospheric drag slows the shells down eventually. And if a pilot accelerates and maneuvers in the wrong way after firing the cannon, the aircraft could be unexpectedly reunited with its recently departed rounds.

Click through; this is also not the first time something like this has happened. In fact, the first time was in 1956.

Also hilarious: the gun in question, a 20mm Vulcan cannon, can fire 6,000 rounds a minute — but the F-16 only carries 511 rounds, or about 5 seconds of fire.

Rule #1 Online: Nobody else needs your password

So Facebook has apparently been asking people for their email passwords, which is just amazingly wrongheaded and evil. I’m sure plenty of folks gave them up, too. But here’s the thing:

There is never a good reason to give your password to anyone. Note I didn’t say “email password;” I mean literally ANY password. Maybe we get a little flexible about this where spouses come into play, or that shared Hulu account, but for things like email: NOPE.

It’s ABSOLUTELY a red flag if anyone online ever asks you for a password to some other site, as Facebook does here. There’s no reason for Facebook to need this information. There’s no reason for you to give it to them. Seriously. NO GOOD CAN COME FROM THIS.

This Week’s Best Thing On The Internet

So, Tom Hiddleston did a funny little vitamin commercial for the Chinese market, and it’s notable for lots of reasons if you’re interested in that sort of thing. For one thing, it was released on Hiddleston’s own Weibo channel, so it’s not just advertising native to social media, it’s advertising tailor-made for a Chinese social media platform — and is meant to be consumed on phones (hence the vertical video).

Anyway, it’s apparently hugely successful in China, but lots of it seems super weird to Western consumers — not the least of it being the weird “immersive” style, and obviously the food choice.

This would all be fuel for discussion on its own, but then Phil Wang made something amazing with it, and that’s why I’m posting it here. Enjoy.
