TED-Ed, with the help of gastroenterologist Dr. William D. Chey, has put together a wonderfully concise 5-minute explainer about gluten — and why it has only recently been perceived as a health problem.
Ever wonder what would happen to a deep sea fish if it swam too close to the surface, or why scuba divers have to ascend very slowly after a deep dive? The latest TED-Ed video provides the answers as it explains the physics of pressure change.
The visual acuity of our canine companions is about 20-40% as good as ours. But the average dog's nose is 10,000 times more sensitive to odors than the human nose. As this fascinating TED-Ed video shows, they don't so much see the world as they smell it.
In this newly released video from the folks at TED-Ed, educator Dennis Wildfogel teams up with animator Ash Barker to explain not only what the universe is made of, but what it took for those cosmological building blocks to get where they are today.
It might seem like a simple question, but as this TED-Ed video beautifully illustrates, the task of measuring an object's speed as it's traveling through space is far more complicated than it looks — even if you're aboard the starship Enterprise.
Today we have birds. Millions and millions of years ago we had feathered dinosaurs. What happened in between?
Really loving this fantastic three-minute intro to the early days of the Universe, narrated by CERN physicist Tom Whyntie.
Current estimates put the number of stars in the Milky Way at well over 100 billion, each of which is thought to have at least one planet in its orbit. Assuming at least some of these planets have given rise to intelligent life capable of communicating with Earth, why haven't we heard from them yet?
Check out the wave-particle duality as presented by Colm Kelleher and animated by Nelson Diaz for TEDEd; it's a clever explanation to a longtime quantum conundrum. Even better: it's delivered with a lilting Irish accent — which makes the historical bit about the eye-horses that much more entertaining.
English is widely recognized as one of the world's most difficult languages, due in no small part to its deep, highly irregular orthography. Niggling quirks in pronunciation, freaky verb conjugations, and seemingly non-sensical spelling conventions can all make English downright bewildering, even to native speakers.…
Most of us are familiar with the telltale signs of zombiedom. Incoherent moans. Gurgling. A lumbering gait. Insatiable hunger. But have you ever wondered what's actually going on inside the heads of the walking dead?
All right — so maybe not everything, but this expertly crafted animation is easily one of the most lucid and entertaining introductions to gravitational forces we've ever come across. Too busy to watch the five minute crash course? (You're not; just watch it.) Here's the upshot: everything is attracted to everything…
Remember: I said quickly. We need an answer, and we need it in the next sixty seconds. Oh, and no using Google, either.
Call me anal-retentive, but I find it more than a little ironic that a TED-Ed video about the importance of units, whole number place value, decimal place value, and fractions features an animation of apples being sold for 0.79 cents each (see 00:25).
Last month, the folks at TED announced their new education initiative. They call it "TED-Ed," and it's part of a brand new platform designed to "capture and amplify the voice of the world's greatest teachers" in the form of short, sharp, animated videos. On Wednesday, TED-Ed took a big step forward by unveiling the…
