In honor of World Health Day, here are 7 TED-Ed Lessons for a healthier you: 1. How do carbohydrates impact your health? The things we eat and drink on a daily basis can impact our health in big ways. 2. When you eat something loaded with sugar, your taste buds, your gut and your brain all take notice. 3. Water is essentially everywhere in our world, and the average human is composed of between 55 and 60% water. 4. In the United States, it’s estimated that 30 percent of adults and 66 percent of adolescents are regularly sleep-deprived. 5.
Our hard-wired stress response is designed to give us the quick burst of heightened alertness and energy needed to perform our best. 6. We have over 600 muscles in our bodies that help bind us together, hold us up, and help us move. 7. If you lined up all the blood vessels in your body, they’d be 60 thousand miles long. Why do your knuckles pop? - Eleanor Nelsen. Want to learn the latest on this topic? Read the recent publication: Real Time Visualization of Joint Cavitation aka “knuckle cracking!”
Then listen to the latest Morning Edition at NPR: Why Knuckles Crack! Scroll down at the site and watch an MRI of knuckle cracking in real time to see the “pop” during the “pull my finger study!” Here’s another interesting physiological phenomenon that has to do with gas solubility: decompression sickness, or “the bends.” When divers are deep underwater, they experience ambient pressure much higher than it is on land. The divers’ air tanks must be at a correspondingly high pressure to allow air to flow out of the tank into the mask. Learn about the “bends” from the U.S.
These escaping bubbles can cause a variety of symptoms including joint pain, rashes, shortness of breath, headaches, and fatigue. Ever wonder how underwater organisms avoid the bends? What really happens to the plastic you throw away - Emma Bryce. If you watched this video, you’re probably interested in how plastics are made, and what impact they have on the environment. For starters, you might want to watch this video that shows you how plastic bottles are produced.
The American Chemistry Council also has some helpful guidelines on how the material is manufactured, what different types there are, and what role monomers and polymers play in the manufacturing process. (What are monomers and polymers anyway? You can read more about how they’re used in plastics, here.) Moving on from the molecular stuff, plastic also has more visible impacts on the earth.
Talking of hazards, plastic in the ocean is one of the greatest hazards of all. But there’s hope: plastics can be recycled, after all. Finally, this TED speaker shares some ‘tough truths about plastic pollution’, and in this talk, you can meet the man who first discovered those ‘garbage patches’ in the sea. Watch these other TED Ed lessons on Plastics and Pollution!

Use The Rule Of 72 To Estimate When Your Money Will ... Expand Your Mind - Puzzles and Brain Teasers. To expand your mind you need to learn new facts and develop new modes of thinking that will make the information that you already know more useful. Solving the following problems requires a combination of world knowledge, mathematics, common sense, logic, and science (chemistry, physics). This is not an IQ test. There is no time limit. To expand your mind, do not look at the answers until after you have made an honest effort to figure out the problems.

The Chicken and Egg Problem A chicken farmer has figured out that a hen and a half can lay an egg and a half in a day and a half.

Questions no one knows the answers to - Chris Anderson. 1) Ask teachers for their favorite unanswered questions. Create a large display space in your school or in some other public area in your community where people can write down other big questions, and/or identify which of the already-posted questions seems especially intriguing to them. 2) Anderson asks, “Why do so many innocent people and animals suffer terrible things?”

Amazing Run-Through of 17 British Accents. 29 Delicious Slow Motion GIFs. Serial killers aside, this week’s full post is kind of intense and just taking more time than usual. It’ll go up early next week. In the meantime, these 29 succulent slow motion GIFs will serve as a distraction. Let’s start with what happens if you shoot a bullet into a steel wall. The wall wins. But a watermelon loses. Doesn’t go particularly well for the egg either.
Squishy pool table edge. The tip of a pool cue distorts slightly when it hits the ball. Things popping. Unpleasant. It seems like a drinking dog is just licking the water with his dumb tongue, but he’s actually doing stuff. Officially a monster. I wonder who the first human was to realize this happened when you heated up corn. A violin being creepy. Lightning actually worms its way down to the Earth and the big bolt you see is generated when it first touches the ground. Not really sure what the glass was doing between when it was hit and when it shattered. 2 for 1. The ball gooeys around the bat. But it gooeys when it hits a metal wall.

These Are The Things That Make Up A Successful Person And An Unsuccessful Person. 18 Things Highly Creative People Do Differently. This list has been expanded into the new book, “Wired to Create: Unravelling the Mysteries of the Creative Mind,” by Carolyn Gregoire and Scott Barry Kaufman. Creativity works in mysterious and often paradoxical ways. Creative thinking is a stable, defining characteristic in some personalities, but it may also change based on situation and context.
Inspiration and ideas often arise seemingly out of nowhere and then fail to show up when we most need them, and creative thinking requires complex cognition yet is completely distinct from the thinking process. Neuroscience paints a complicated picture of creativity. As scientists now understand it, creativity is far more complex than the right-left brain distinction would have us think (the theory being that left brain = rational and analytical, right brain = creative and emotional). While there’s no “typical” creative type, there are some tell-tale characteristics and behaviors of highly creative people. They daydream. They “fail up.” Science and Space Facts, Science and Space, Human Body, Health, Earth, Human Disease - National Geographic.

Everyone Was Completely Speechless. She’s The Only Woman In The World To Do This! Giant Vortex Cannon. Watch this bead chain loop defy gravity and bend physics | Science! Science is unendingly cool because it can consistently confound the expectations of researcher and layman alike. Case in point, what do you figure would happen if you had a bead chain coiled up in a small container, then pulled one end out?
You probably didn’t guess that it would leap up and uncoil like a tiny metallic snake, but that’s what happens. This demonstration is sometimes called Newton’s Beads. It’s an unexpected trick of physics, but the mechanics behind it are fairly simple. The effect seen above in slow motion is a function of momentum. It’s not a smooth arch like you might expect, even after coming to terms with the fact that it’s happening.
