Pianos can't be perfectly tuned - it's a mathematical fact!

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!

Dickinsonia might be the oldest known member of the animal kingdom, and the origin of birdsongs from the syrinx might be a little less mysterious.

What's happening inside our ears when we can hear that ringing? What's happening inside our brains? Sit back, clean the wax out of your ears, and let Michael Aranda explain! ----------

While you might not think about quantum mechanics being part of your everyday life, it turns out that it might play a role in some of the most familiar things, from the sunlight in the trees to the nose on your face!

Have you ever thought you felt your phone vibrate, only to pull it out of your pocket and find that you have no new notifications? If so, you've experienced 'phantom vibration syndrome.' But what causes these mystery sensations, and are...

Where do glaciers and icebergs get their beautiful blue color? This unique blue might be nature's most brilliant, and the color arises in a very special way thanks to some surprising interactions between light and water molecules. Who...

We can now map the interiors of stars by "listening" to their harmonies as they vibrate with seismic waves.

HOMUNCULUS! It's a big and weird word that you may or may not have heard before, but do you know what it means? In this episode of Crash Course Psychology, Hank gives us a deeper understanding of this weird model of human sensation.

Bees, they're important and amazing creatures, and with spring on the way we thought we'd share another round of our favorite bee episodes.

Teach your teacher: the collapse of the Tacoma Narrows bridge WASN'T resonance.

In this video Paul Andersen describes some of the properties of waves. He starts be identifying particles and waves as the only phenomenon that can transfer energy from place to place. He identifies the defining characteristics of...

Communicating underwater is challenging. Light and odors don't travel well, but sound moves about four times faster in water than in air - which means marine mammals often use sounds to communicate. The most famous of these underwater...

Subtle motion happens around us all the time, including tiny vibrations caused by sound. New technology shows that we can pick up on these vibrations and actually re-create sound and conversations just from a video of a seemingly still...

Sound can't actually travel through a vacuum like space, but scientists have learned that there's still plenty to hear.

Electronic music is older than you may think. Enter the theremin - a device that turns your body into part of a capacitor, and allows you to play music without even touching an instrument!

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!

Sound can't actually travel through a vacuum like space, but scientists have learned that there's still plenty to hear.

You’ve probably seen the videos on YouTube turning grapes into fireballs in the microwave. Well, there’s a pretty cool scientific explanation for why a grape is perfect for making plasma.
