The faster the glider goes the more lift the wings make. If the glider flies fast enough the wings will produce enough lift to keep it in the air. But, the wings and the body of the glider also produce drag, and they produce more drag the faster the glider flies. Since there's no...
Back in 2008, when I was getting married, I watched the weather like a hawk. On the big day, I was heartbroken when the forecast came in: 100% chance of rain, and we were planning an outdoor ceremony. I decided to go through with it anyway and take my chances. It turned out to...
There are many things to look forward to in The Legend of Zelda: Tears of the Kingdom, such as the mysteries behind the floating islands, Link’s new Ultrahand ability that lets you craft unique objects, and his fuse ability that lets you make weapons of everyday objects. However, the ...
Since the biceps brachii do cross the elbow joint, they will be doing a lot of work here as well. And these two prime movers will get assistance from the brachioradialis muscle on the back of the forearm. You’re also performing wrist supination. Twisting your palm up will be handled m...
Make a complete circular cast above your head in an underhand arc against the current. You can make as many circles as you need to line things up perfectly so that your fly lands where you want it. If it's windy, you can generate greater line speed by making tighter, faster-moving ci...
Just 50 years ago, no one knew why the Earth has mountains. Now we do. This is the story of how we figured it out - and how we keep learning.
Begin whipping the steering wheel around in the direction you want to travel. The faster you can do this, the better, as it’s the rapid change in direction that’ll cause the rear wheels to lose grip. Note that you’re not aiming for full lock: do that and your car will suffer the...

Adult visual performance differs with angular location –it is better for stimuli along the horizontal than vertical, and lower than upper vertical meridian of the visual field. These perceptual asymmetries are paralleled by asymmetries in cortical surfa
Once it reaches the top of the arc created by its rocket boost, it loses momentum and falls back to Earth. To slow its descent, SpaceShipOne transforms into a configuration that exposes the greatest surface area to the air flow. This creates tremendous drag and slows the ship down as it ...
