Designer Jared Ficklin creates wild visualizations that let us see music, using color and even fire (a first for the TED stage) to analyze how sound makes us feel. He takes a brief digression to analyze the sound of a skatepark -- and...

Is our obsession with efficiency actually making us less efficient? In this revelatory talk, writer and historian Edward Tenner discusses the promises and dangers of our drive to get things done as quickly as possible -- and suggests...

Some people can eat raw jalapeños like they're apples. Why do some people have a high tolerance for spicy food while others can't stand it?

The Harlem Renaissance produced many remarkable artists, writers, and thinkers. Today we'll talk about one of the most interesting minds of the time, Zora Neale Hurston. Hurston was an anthropologist by training, and spent much of her...

You may think of single-celled organisms as being microscopically small, but these ocean dwellers are a little heftier than that.

The Apollo 1 fire was a tragedy and a huge wake-up call for NASA, causing them to get much more serious about their safety procedures and technology, and also changed their attitude towards spaceflight in general.

While not used much any more as a primary source of light, candles are still everywhere, from an aroma in a bathroom to a mood during dinner. That is, until they’re gone.

Science is delicious.

Fire seasons can be bad enough on their own, but it turns out sometimes forest fires that appeared to be dead, turn out to have just been lying in wait.

Volunteer firefighter Mark Bezos tells a story of an act of heroism that didn't go quite as expected -- but that taught him a big lesson: Don't wait to be a hero.

You know how you somehow end up getting smoke in your eyes wherever you stand around a bonfire? Well, it turns out that’s not a curse! It’s much more easily explained with physics. "The more protractors, the better the party." ~Hank Green

So, what is fire, exactly? What causes fires in the wild, and how do we put them out? SciShow answers your burning questions about the science of fire. (See what we did there?)

How do you remember where you parked your car? How do you know if you're moving in the right direction? Neuroscientist Neil Burgess studies the neural mechanisms that map the space around us, and how they link to memory and imagination.

You know metal can get really hot, and you probably know that it can melt. But can it burn? Hank shows you how you can burn a hunk of metal like you're some kinda superhero (just be careful, please), and he explains how, in chemistry,...

Before the creation of humanity, the Greek gods won a great battle against a race of giants called the Titans. Most Titans were destroyed or driven to the eternal hell of Tartarus. But the Titan Prometheus, whose name means foresight,...

In this video Paul Andersen explains how heating is the transfer of energy (heat) from a warmer object to a cooler object. Heat can be transferred through conduction, convection and radiation. At the microscopic level conduction...

Why did some of Samsung's Galaxy Note7 phones explode? And what can Tardigrades teach us about protecting our DNA?

Jessi and Squeaks are thinking of visiting the redwoods, the tallest trees in the world, but there's lots for them to learn before they make their trip! First Grade Next Generation Science Standards Disciplinary Core Idea: LS1.A:...

Mirror neurons are a very cool part of our brains but some people are taking it way further by making claims that they are responsible for telepathy and ESP. It goes without saying that this isn’t true, but what exactly do mirror neurons...

Over the course of her fearless career, extreme action specialist Elizabeth Streb has pushed the limits of the human body. She's jumped through broken glass, toppled from great heights and built gizmos to provide a boost along the way....

Whether you're out camping, cooking, or snuggled up in front of your fireplace, you know that fire is hot! But why? Join Jessi and Squeaks to learn how fires turn wood or other fuel into useful heat!

Chemistry is the study of matter - stuff, and how it interacts with other stuff. Even though chemistry doesn't make a lot of news these days, chemists are making discoveries that change lives all the time. If Hank had to narrow down all...

Today we’re going to explain how exchangers...exchange heat. We’ll look at concentric tubes, finned tubes, plate heat exchangers, and shell-and-tube heat exchangers. And we’ll look at some equations to help us sort through heat transfer...

How do we know what matter is made of? The quest for the atom has been a long one, beginning 2,400 years ago with the work of a Greek philosopher and later continued by a Quaker and a few Nobel Prize-winning scientists. Theresa Doud...
