What is a differential equation, the pendulum equation, and some basic numerical methods

The formula for the cross product can feel like a mystery, or some kind of crazy coincidence. But it isn't. There is a fundamental connection between the cross product and determinants.

Flatulence is a daily phenomenon. In fact, most human beings pass gas 10-20 times a day (yes, that includes you). Where does your bodily gas come from? Purna Kashyap takes us on a journey into the intestines, shedding light on how gas is...

The world has a lot to thank Henrietta Lacks for, and yet many do not know what she has contributed. From helping to create the polio vaccine to the study of radiation, Henrietta and her HeLa cells have changed the world.

Eigenvalues and eigenvectors are one of the most important ideas in linear algebra, but what on earth are they?

This video is about how we don't just need energy to power our lives, we need *low entropy* energy! Thanks to Google Making and Science for supporting this series, and to Sean Carroll for collaborating on it!...

In this video Paul Andersen explains how a spontaneous process may take either the thermodynamically controlled or the kinetic controlled pathway. If the activation energy determines the path taken then the process is under kinetic...

How to think about implicit differentiation in terms of functions with multiple inputs, and tiny nudges to those inputs.

A quick explanation of e^(pi i) in terms of motion and differential equations

For the nearly 20 million Americans with a felony record, punishment doesn't end after their prison sentence. Sociologist Reuben Jonathan Miller sheds light on the aftershocks of mass incarceration through the stories of people who've...

Rebeca Hwang has spent a lifetime juggling identities -- Korean heritage, Argentinian upbringing, education in the United States -- and for a long time she had difficulty finding a place in the world to call home. Yet along with these...

An animated introduction to the Fourier Transform, winding graphs around circles.

"I Don't Think It Means What You Think It Means" examines scientific theories that have taken on a life of their own in popular culture & we help you understand what they really mean in scientific terms. Today we take on Schrodinger's...

A puzzle involving colliding blocks where the number pi, vey unexpectedly, shows up.

What do you see in clouds? Bunnies? Zombies? The face of Nic Cage? There are some kinds of clouds that, while rare, make even weirder shapes -- like pancakes, rolling cylinders, and shimmery rainbows.

Dino stops by the Fort to learn all about dinosaurs with Jessi and Squeaks! Did you know that dinosaurs were on Earth for so long that not all dinosaurs lived at the same time?!

What shape do you most associate with a standard analog clock? Your reflex answer might be a circle, but a more natural answer is actually a torus. Surprised? Then stick around.

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.

Inspired by Gene Roddenberry's Star Trek, physicist Miguel Alcubierre set out to transform one of the cornerstones of science fiction iconography, the Warp Drive, into reality. But is it even possible? Can we "warp" the fabric of reality...
