A method for thinking about high-dimensional spheres, introduced in the context of a classic example involving a high-dimensional sphere inside a high-dimensional box.

Conservation laws are among the most important tools in physics. They feel as fundamental as you can get. And yet they're wrong - or at least they're only right sometimes. These laws are consequences of a much deeper, more fundamental...

The simple eye movements involved in EMDR therapy are supposed to help you reprocess traumatic memories, but does it actually work?

Today we're going to talk about robots! Robots are often thought as a technology of the future, but they're already here by the millions in the workplace, our homes, and pretty soon on the roads. We'll discuss the origins of robotics to...

Thanks to Google Making and Science for supporting this series, and to Sean Carroll for collaborating on it!



This video is about why there's no such thing as cause and effect at the level of fundamental particle...

According to some of the latest New Horizons data, Pluto's got flowing nitrogen ice and only half the atmosphere it had two years ago. Plus, the latest batch of exoplanets includes a world that's a lot like Earth... probably.

An introduction to what a derivative is, and how it formalizes an otherwise paradoxical idea.

In this video Paul Andersen explains how information is processed in in animals. He starts by describing the different forms of information and how they are received by receptors. He explains how information is received by the brain...

Alternative energy is great, but our infrastructure isn't exactly equipped to handle it. So scientists are coming up with other ways to use it, including turning it into food.

Today Hank talks with Dr. Cara Nelson about invasive plants that use toxic chemicals and rapid reproduction to outcompete native plants, and Jessi brings some adorable invasive birds. Dr. Nelson is a professor of Restoration Ecology at...

Cartoons are the best! But you know the characters in them aren't real... so how do they move around like that? Today's experiment will teach you all about the different illusions animation uses to trick your brain and bring drawings to...

This video is about the famous 'Twins paradox' of special relativity, how time can appear to be faster for two different observers at the same time, and which twin really is older (or younger) - the one who stays on earth or the one who...

In this video Paul Andersen attempts to explain the age old questions - What is Energy? Even though it comes in many forms one of the defining characteristics of energy is that it is conserved over time. He then explains that all...

What if you could take a smell selfie, a smelfie? What if you had a lipstick that caused plants to grow where you kiss? Ani Liu explores the intersection of technology and sensory perception, and her work is wedged somewhere between...

Although one third of the population suffers from motion sickness, scientists aren't exactly sure what causes it. Like the common cold, it's a seemingly simple problem that's still without a cure. And if you think it's bad on a long...

In this video Paul Andersen explains how object interactions can add or remove mass or energy from a system.

A quick explanation of e^(pi i) in terms of motion and differential equations

Why does the universe seem to be moving in one particular direction?

Today on SciShow News we talk about a new research effort that is aiming to revolutionize how we treat disease. We also discuss the video where Boston Dynamics shows off it's new version of the Atlas robot by using a hockey stick to mess...

This video is about the Portal Paradox - a paradox in the video game Portal (and Portal 2) regarding whether or not a companion cube passing through a moving portal plops out of the other end with no speed (velocity,...

Taking design cues from origami, robotician Jamie Paik and her team created "robogamis": folding robots made out super-thin materials that can reshape and transform themselves. In this talk and tech demo, Paik shows how robogamis could...

Sampling isn't about "hijacking nostalgia wholesale," says Mark Ronson. It's about inserting yourself into the narrative of a song while also pushing that story forward. In this mind-blowingly original talk, watch the DJ scramble 15 TED...

The star-mapping satellite Gaia has found more than 20 stars speeding across the Milky Way toward intergalactic space. There are just a few things that can slingshot a star out of a galaxy and all of them take some extreme gravitational...

NASA releases a Giant Ballooon and we learn more about the Martian ice age!
