Have you ever noticed that airplane wings curl up at the very end? Why is that? Called winglets, the curled tips shrink the vortices at the end of the wing, which in turn improves its fuel efficiency.
Last month, engineers found small cracks in the wings of Singapore Airlines' A380s. Now, Qantas has been forced to ground one its A380s because of the same problem.
You probably think that a wing lifts an airplane because the airflow moving over the top has a longer distance to travel and "needs to go faster to have the same transit time as the air travelling along the lower, flat surface." Well, you are wrong.
Certain butterfly species are poisonous, providing a deadly defense against predators. Over time, different butterfly species have evolved the same color patterns, basically telling predators to avoid all butterflies of that appearance. This is the mystery of convergent evolution.
This chair is notable in two ways. One, it's the largest single piece of bendwood used to make a chair, and two, it's the only chair tested by NASA and certified by The Space Foundation.
Scale is everything: We knew iriver's Wing touchscreen UMPC was seriously compact, but didn't know just how small it was. It's still a complete prototypeâ€”you're looking at dumb plastic, and the top half even sorta fell off the hingeâ€”but we convinced them to pull it out of the glass case so we could do a quick…
The Goods: The iriver Wing is a cute little UMPC with a touchscreen and 4GB of flash storage. It's got Wi-Fi, obviously, and supposedly is instant-on. No word on the battery life. The Bads: It runs Windows CE Pro for the OS, and the keyboard looks like it could be difficult to pound on.
Is this RAM Wing 100 yacht by Levi Designs a catamaran or a monohull? It's both, starting out in front is a catamaran and ending up as a monohull in the stern. The most remarkable aspect of this design concept is its tremendous speed, 100 knots with a range of 2000 nautical miles. That's not bad for a giant 328-foot…
As if it wasn't cool enough already to be an Apache pilot, these pictures arrive to make us even more envious. If an Apache is nearby a rescue situation then they will sometimes try to lend a hand—even though they only have two seats. The lucky/unlucky copilot has to step outside and sit on the wing stub, to make room…
The T-Mobile Wing is on one hand, another HTC smartphone with that same old HTC form factor. On the other, it's the first Windows Mobile 6 Professional phone on this side of the pond...either pond.
T-Mobile customers have waited a long time for an upgrade to the trusty MDA, its only Windows Mobile Pocket PC phone—and only Windows Mobile phone with a keyboard other than the Dash—but all that patience is about to pay off.
