Mercury, a.k.a. quicksilver, is famous for being a liquid at room temperature...and also below room temperature. But you can't use a high school chem class to explain why. Instead, we need a little help from Einstein.

Most trees reach for the sun – but not the weeping willow. Why?

Fast Radio Bursts were puzzling physicist for quite some time. They were thought to be the result of large cataclysmic events such as supernovae, but this theory was proven wrong when it was discovered that they could repeat themselves....

A few years ago, the king decided your life would be forfeit unless you tripled the gold coins in his treasury. Fortunately, a strange little man appeared and magically performed the feat. Unfortunately, you promised him your first-born...

A beutiful derivation of a formula for pi. At first, 1-1/3+1/5-1/7+1/9-.... seems unrelated to circles, but in fact there is a circle hiding here, as well as some interesting facts about prime numbers in the context of complex numbers.

Today, we’re going to take a look at how computers use a stream of 1s and 0s to represent all of our data - from our text messages and photos to music and webpages. We’re going to focus on how these binary values are used to represent...

Tropical storms can be devastating but at least we usually know where they're going to appear. The exception being a very strange week in 1996, on Lake Huron.

This is episode 7 of our animated series "Think Like A Coder." This 10-episode narrative follows a girl, Ethic, and her robot companion, Hedge, as they attempt to save the world. The two embark on a quest to collect three artifacts and...

New York Times columnist David Pogue takes aim at technology’s worst interface-design offenders, and provides encouraging examples of products that get it right. To funny things up, he bursts into song.

The hard choices -- what we most fear doing, asking, saying -- are very often exactly what we need to do. How can we overcome self-paralysis and take action? Tim Ferriss encourages us to fully envision and write down our fears in detail,...

In this video Paul Andersen shows conceptual thinking in a mini-lesson on orders of magnitude.

Scale models - a representation that has been reduced or enlarged to a specific
scale
Orders of magnitude - is an approximation...

Extreme weather sometimes happens in very specific areas thanks to extreme surface temperature differences.

In this episode of SciShow Talk Show Hank chats with Chad Larrabee of Montgomery Distillery about the science of distilling alcohol. Special guest is Jessi Knudsen Castañeda of Animal Wonders with Groucho the hedgehog.

Woody Norris shows off two of his inventions that use sound in new ways, including the Long Range Acoustic Device, or LRAD. He talks about his untraditional approach to inventing and education, because, as he puts it: "Almost nothing has...

We use seismographs to record the time, location and magnitude of earthquakes as they happen. But in the last three decades, a new field of study has emerged that is learning to track these details about earthquakes of old using the...

Bad news: your worst enemies are at the gate. Your fledgling kingdom guards the world's only herd of tiny dino creatures. To you, they're sacred. To everyone else, they're food. The three closest nation-states have teamed up to smash...

You’d never tell just by staring out from a sandy beach, but the coasts are gradually getting darker, and the effects of this darkening are only beginning to be understood.

Paul Andersen shows you how to calculate the ch-squared value to test your null hypothesis. He explains the importance of the critical value and defines the degrees of freedom. He also leaves you with a problem related to the animal...

What makes a great leader? Management theorist Simon Sinek suggests, it’s someone who makes their employees feel secure, who draws staffers into a circle of trust. But creating trust and safety — especially in an uneven economy — means...

When you think of matrices as transforming space, rather than as grids of numbers, so much of linear algebra starts to make sense.

Cats and dogs have it tough: They can't use straws, or tip a cup up to their mouths to drink. Instead, they have to use their tongues and a few different physics tricks to quench their thirst.

Today we’re going to create memory! Using the basic logic gates we discussed in episode 3 we can build a circuit that stores a single bit of information, and then through some clever scaling (and of course many new levels of...

In this video Paul Andersen explains the important properties of solutions. A solution can be either a solid, liquid or gas but it must be homogeneous in nature. The solutes can not be separated with a filter and so either...
