Robots are designed for speed and precision -- but their rigidity has often limited how they're used. In this illuminating talk, biomedical engineer Giada Gerboni shares the latest developments in "soft robotics," an emerging field that...

Singer/guitarist Raúl Midón performs "All the Answers" in a world premiere at TED2007, followed by the sprightly "Tembererana."

In this video Paul Andersen shows conceptual thinking in a mini-lesson on stability and change. Two examples are included in the video and two additional examples are included in the linked thinking slides. ...

The earliest time measurements were observations of cycles of the natural world, using patterns of changes from day to night and season to season to build calendars. More precise time-keeping eventually came along to put time in more...

To get humans on Mars we're going to need some innovative tech that can move lots of things at high speed. Luckily, we might already have something that can do the job.

Paul Andersen shows you how to compare DNA sequences to understand evolutionary relationships. He starts with a brief introduction to cladograms and evolutionary relationships. He shows you how to classify DNA relationships using a...

These snakes climb like lassos. #shorts #science #SciShow

Meet the friendly robot that could deliver your next burrito. Ali Kashani introduces us to Postmates' autonomous delivery robot and explains how it could help reduce carbon emissions and free up valuable real estate in cities everywhere....

At some point, you've probably learned about the five senses: sight, sound, smell, taste, and touch. However, the classic list doesn't account for all the sensations we experience and use to navigate the world around us!

The cross product is a way to multiple to vectors in 3d. This video shows how to visualize what it means.

Paul Andersen reflects on the flipped classroom

Octopuses have tons of strange and amazing adaptations that help them live their best lives underwater. And those incredible traits could help us in many ways.

This video is about gravitational waves in the weak field limit as discovered by the LIGO collaboration, explained by parallels to electromagnetic radiation, sound waves, water waves, etc. I want to see Cat LIGO ASAP!

There are more than 20,000 species of bees, all of which buzz when they fly, and many of which also do it to communicate. But some bees buzz for a completely different reason that has nothing to do with communication or flight!

There’s a reason behind the saying “fish out water.” Fish don’t tend to do well if they’re not immersed in liquid. But walking catfish are surprisingly adept at making their way on land.

You've felt cold before. Sometimes it's cold outside. But what if I told you that "cold" isn't real? There's no substance or quantity called "cold" in science. We can't measure the amount of "cold" in something. Instead it's about what's...

In this video Paul Andersen explains how the total energy of a system is the combination of kinetic, potential and internal energy of the objects. He then shows you how to calculate the kinetic energy, gravitational potential energy,...

When catastrophe strikes, art prevails -- and has done so for centuries. In this fascinating talk, writer and director Cara Greene Epstein places the closing of theaters during the coronavirus pandemic in a historical context, exploring...

Archimedes once said "Give me a place to stand, and I shall move the Earth." While the idea of a person moving such a huge mass on their own might sound impossible, chances are you've seen this idea in action at your local playground....

In this video Paul Andersen explains how thermodynamic and equilibrium reasoning can be related through changes in free energy and the equilibrium constant. When the delta G is negative the reaction shifts to the right or favors...

In this episode of SciShow we look at the most fascinating birds that hover!

In this video Paul Andersen explains how energy can be harnessed was water moves through a turbine. Three types of systems are discussed in the video; run-of-the-water, impoundment, and tidal. Several advantages and disadvantages of dams...

The feeling of a kicking fetus is perhaps one of the more fun parts of having a baby, but these movements serve a purpose well beyond letting you know that that little thing is in there!

When under anesthesia, you can't move, form memories, or -- hopefully -- feel pain. And while it might just seem like you are asleep for that time, you actually aren't. What's going on? Steven Zheng explains what we know about the...
