You'd think if we can tell when a star is about to implode that we could predict when a giant hole is about to open up here on earth and ruin our day. So why are sinkholes still so hard to predict?

After much debate, the realm has decided dragon jousting may not be the best way to choose its leaders, and has begun transitioning to democracy. Your company was hired to survey the citizens of the land and predict which candidate will...

Over the last few years astronomers have been doing more and more research based on string theory, and thanks to modern telescopes the results are... less than encouraging

Objects that fly faster than the speed of sound (like really fast planes) create a shock wave accompanied by a thunder-like noise: the sonic boom. These epic sounds can cause distress to people and animals and even damage nearby...

After a long day working on the particle accelerator, you and your friends head to the arcade to unwind. The lights go out for a second, and when they come back, there before you gleams a foosball table. Always game, you insert your...

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,...

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...

Why is my weather app sometimes wrong? Well it has a lot to do with wind. Jet Streams, air cells, the shape and movement of the Earth... there are a lot of things that make weather a little unpredictable. In this episode of Crash Course...

You might have heard about animals behaving oddly right before an earthquake hits. But are these reports more than just anecdotes?

We pretty much know for sure that the universe was once extremely small, and extremely hot. And we know that something set it in motion, expanding rapidly and continuing to do-so today. But the actual moment of 'the Big Bang' is still a...

The current hurricane category scale doesn’t accurately convey the danger of a storm, because it doesn’t account for a hurricane's most destructive factors.

Hank helps us understand the difference between the colloquial meaning of randomness, and the scientific meaning, which is also known as stochasticity. We will learn how, in fact, randomness is surprisingly predictable.

There are over 13,000 active seismic stations out there, producing far more data than seismologists have time to go through. So, researchers set up a showdown of humans versus machines to sift through all this information and, in the...

"Most of what we send into outer space never comes back," says astrodynamicist and TED Fellow Moriba Jah. In this forward-thinking talk, Jah describes the space highways orbiting earth and how they're mostly populated by space junk....

Scientists have developed reliable early warning systems for tsunamis caused by earthquakes. The problem is, earthquakes aren't the only things that cause tsunamis.

You're on an airplane when you feel a sudden jolt. Outside your window nothing seems to be happening, yet the plane continues to rattle you and your fellow passengers as it passes through turbulent air in the atmosphere. What exactly is...

Great ideas are like electricity -- they snap into sharp focus and sprint from place to place. What's the best way to capture them? Bozoma Saint John, Chief Marketing Officer at Netflix, makes a compelling case to move away from an...

Hank talks about why it is so difficult for scientists to predict earthquakes in the short term.

I'm tall. Most of the people in my family are tall. Does that mean my son will be tall? Turns out the inheritance of height is a lot more complicated than we thought. Scientists know that nature (genes) and nurture (environment) both...

Your love for Rihanna or Tom Hardy may be unrequited, but that doesn't necessarily make it unhealthy.

Coming up with brand new drugs is all about pinpointing and exploiting a disease’s weakness. A big part of perfecting drug design will be learning to predict how proteins get their shapes because that has everything to do with how both...

Ever wonder why sometimes the airplane you're flying on decides to lurch suddenly and cause your little baggie of peanuts to spill all over the place? Join Hank on SciShow today as he explores the in and outs and the ups and downs of...
