This video is about the line between Brown dwarfs and gas giant planets (aka...

We have so many different emotions that pop up from time to time, so Squeaks and Jessi are playing a guessing game while they watch videos that remind them why we have certain emotions!

We increasingly make decisions based on short-term goals and gains -- an approach that makes the future more uncertain and less safe. How can we learn to think about and plan for a better future in the long term ... like,...

Pearl Arredondo grew up in East Los Angeles, the daughter of a high-ranking gang member who was in and out of jail. Many teachers wrote her off as having a problem with authority. Now a teacher herself, she's creating a different kind of...

Solar sail technology was once only theoretical, but it's now being developed to propel spaceships. How did the first solar sails get into space, and why?

As we move through the world, we have an innate sense of how things feel -- the sensations they produce on our skin and how our bodies orient to them. Can technology leverage this? In this fun, fascinating TED-Ed lesson, learn about the...

In 2013, a group of researchers wanted to create an AI system that could beat every Atari game. They developed a system called Deep Q Networks (DQN) and less than two years later, it was superhuman. But there was one notable exception....

After serial photography became a thing, it wasn't long before motion pictures started to develop. And, at the front of that development was Thomas Edison, who you may know as an inventor and business person. In this episode of Crash...

Ten years ago, researchers thought that getting a computer to tell the difference between a cat and a dog would be almost impossible. Today, computer vision systems do it with greater than 99 percent accuracy. How? Joseph Redmon works on...

Reggie Watts' beats defy boxes. Unplug your logic board and watch as he blends poetry and crosses musical genres in this larger-than-life performance.

Normal interplanetary travel uses lots of fuel, but taking advantage of some quirks of gravity can let us travel between planets using hardly any fuel at all.

Our neighboring star Betelgeuse got noticeably dimmer a few months ago, and thanks to the Hubble telescope, we recently figured out what was going on. Also, the Arecibo Observatory in Puerto Rico suffered some damage this week.

Most of us will do anything to avoid being wrong. But what if we're wrong about that? "Wrongologist" Kathryn Schulz makes a compelling case for not just admitting but embracing our fallibility.

Paul Andersen introduces science for the science classroom. He starts with a brief description of Big Data and why it is important that we prepare future scientists to deal intelligently with large amounts of data. He explains the...

Many of the inanimate objects around you probably seem perfectly still. But look deep into the atomic structure of any of them, and you'll see a world in constant flux - with stretching, contracting, springing, jittering, drifting atoms...

Goats are amazing creatures, but there's a lot more than meets the eye.

In the late 16th century, Tycho Brahe built an observatory on an island and collecting some of the most accurate data ever. He also lost his nose in a duel with a classmate -- over who was the better mathematician.

So, what exactly is a scientific revolution? And are they more than just moments in time Historians use to mark the beginning and ending of things through time? In this episode we'll look into some ideas and people named Nick and how...

In this video Paul Andersen explains how the electrochemical gradient is a combination of the chemical and electrical gradient of ions. As ions move across a membrane the potential change creates a hidden force that isn't always apparent.

What would a music video look like if it were directed by the music, purely as an expression of a great song, rather than driven by a filmmaker's concept? Designer Jakob Trollback shares the results of his experiment in the form.

They're slippery. They're slithery. And while they totally look like underwater snakes, eels are, in fact, unique fish that can breathe through their skin and even survive out of water. James Prosek tracks the life journey of Eli the...

Anand Agarawala presents BumpTop, a user interface that takes the usual desktop metaphor to a glorious, 3-D extreme, transforming file navigation into a freewheeling playground of crumpled documents and clipping-covered "walls."

Gravity may be doing a lot more than just keeping us planted on the Earth. Scientists are learning that it’s also a key player in how we perceive things.
