Why Earthquakes Are So Hard To Predict

Physics
Scientists are trying to figure out if they can predict big earthquakes by simulating small quakes in labs and studying big quakes under the ocean. Thanks to the University of Rhode Island for sponsoring this video.

How Microwaving Grapes Makes Plasma

Physics
A bisected grape in the microwave makes plasma. But how does it work? A grape is the right size and refractive index to trap microwaves inside it.

Are Negative Ions Good For You?

Physics
Do negative air ions improve mood, anxiety, depression, alertness?

The Inverse Leidenfrost Effect

This Particle Breaks Time Symmetry

Physics
Increasing entropy is NOT the only process that's asymmetric in time.

Which Way Is Down?

Physics
Vsauce host Michael Stevens digs deep into the ever-changing concept of the direction "down," what causes things to fall, and digs into how masses really, really want to pull towards each other in our universe, thanks to gravitational forces.

Einstein's unique way of thinking contributed to his genius

Physics
Robbert Dijkgraaf is a theoretical physicist and Leon Levy Professor at the Institute for Advanced Study in Princeton. He is also the co-author of "The Usefulness of Useless Knowledge." In this video, he explains how Albert Einstein saw the world in a different way from how most scientists see it.

What if the Earth were Hollow?

Physics
What if there were a tunnel through the middle of the earth and you jumped in?

What is entropy? - Jeff Phillips

Physics
There's a concept that's crucial to chemistry and physics. It helps explain why physical processes go one way and not the other: why ice melts, why cream spreads in coffee, why air leaks out of a punctured tire. It's entropy, and it's notoriously difficult to wrap our heads around. Jeff Phillips gives a crash course on entropy.

Meet the Man Who Strapped Himself to a Rocket, For Science

Physics
One man's quest to test the human limits of gravity on the human body.

The Beginning of Everything -- The Big Bang

Physics
How did everything get started? Has the universe a beginning or was it here since forever? Well, evidence suggests that there was indeed a starting point to this universe we are part of right now. But how can this be? How can something come from nothing? And what about time? We don't have all the answers yet so let's talk about what we know.

Earth's Magnetic Field Is Going To Flip, Here's How We Know

Physics
