I don´t know if someone has already mentioned this, but I was watching Frozen when I noticed something. When the wind opens the window, the White Queen (which symbolizes the Queen Elsa) falls from the chess board. Clever detail Disney.
Newton’s third law says that forces come in equal and opposite pairs. This means that when air exerts lift on an airplane, the airplane also exerts a downward force on the air. This is clear in the image above, which shows a an A380 prototype launched through a wall of smoke. When the model passes, air is pushed downward. The finite size of the wings also generates dramatic wingtip vortices. The high pressure air on the underside of the wings tries to slip around the wingtip to the upper surface, where the local pressure is low. This generates the spiraling vortices, which can be a significant hazard to other nearby aircraft. They are also detrimental to the airplane’s lift because they reduce the downwash of air. Most commercial aircraft today mitigate these effects using winglets which weaken the vortices’ effects. (Image credit: Nat. Geo./BBC2)
Joseph Begley lights up rooms in a cheeky way with ‘Slap It’
A quick pinch or squeeze of the ‘slap it’ lamp by London-based designer Joseph Begley brightens up rooms with its warm glow. made from realistic feeling silicone, the cheeky light responds to pressure sensors when it is touched, directly turning it on or off.
Ok can I have
i want a few of every color in a room and have a bunch of people over for a buttslapping rave where we have to make the room flash by slappinbutts
Kenguru’s electric car has no seats, and you drive it by putting your hands on motorcycle-style handlebars. It’s built for wheelchair users, who can roll right through the rear hatch of the car into the driver’s area. The Austin-based…
THIS IS SO COOL.
fucking amazing wow
NO BUT DO YOU UNDERSTAND HOW GREAT THIS IS? DO YOU REALLY? PEOPLE IN WHEELCHAIRS CAN HAVE SMALL CARS NOW, THEY DON’T HAVE TO RELY ON EXPENSIVE LIFTS TO HELP GET THEM INTO CARS, THEY DON’T HAVE TO MODIFY THEIR CARS FOR THEIR NEEDS BECAUSE THE CAR IS ALREADY DESIGNED SPECIFICALLY FOR THEM. THIS IS ACTUALLY SO GREAT AND IT GIVES SO MANY PEOPLE THE OPPORTUNITY TO BE MORE INDEPENDENT AND IT MAKES ME SO HAPPY!
