Despite the rise of renewable energy, the backbone of the power grid is fossil fuels. Adapting the grid to green energy sources is more complicated than flipping a switch.

SciShow Space takes to you a world where the night is always dark, the tides are paltry -- and the days are only 8 hours long. See how different Earth would be if there were no moon!

Learning to throw a boomerang properly takes a lot of practice. And aerodynamics.

We've seen this done in movies right? Well, why don't spaceships have this technology?

Humans have been using microbes to separate minerals from mud since the middle of the last century, so we know biomining works on earth. But how will these tiny miners work in microgravity?

Quantum tunneling happens when a particle seemingly teleports across a barrier. But despite how instantaneous this event sounds, recent research suggests that it doesn’t happen nearly as fast as you might think.

In order to understand how we study the universe, we need to talk a little bit about light. Light is a form of energy. Its wavelength tells us its energy and color. Spectroscopy allows us to analyze those colors and determine an object’s...

The magnetic dipole moment is the torque experienced by a material placed in a magnetic field. The magnetic dipole is an intrinsic property at the magnet, domain, atom, and electron level. A magnetic dipole creates magnetic fields that...

People have been using silkworm silk to make stuff for thousands of years, but spider silk could potentially be even more useful. It's stronger than steel, super stretchy, and could be made into anything from bridge cables to...

You might have heard that Earth is due for a complete flip of its magnetic field. And while our planet does have a history of this behavior, predictions of when it might happen are too complex to estimate a date for.

Does your toilet water drain differently than in the other hemisphere? Is it because of the Coriolis effect? Hank has some things to clarify about these questions, and more in this edition of I Don't Think It Means What You Think It Means.

In this video Paul Andersen explains how at the smallest level all matter is made of fundamental particles; including quarks, electron, photons and neutrinos. He explains how understanding the properties of these particles allows us to...

Hank builds a simple electric motor just powerful enough to make a small screw spin, but also strong enough to blow your mind.

You might not believe it, but the same chemistry that brought us bulletproof vests and modern sailing sails also gave us the technology to build your smart phone. But that doesn’t mean these chemists were thinking about these...

In this video Paul Andersen explains how to write out the electron configuration for atoms on the periodic table. More importantly he shows you why electrons arrange themselves in shells, subshells and orbitals by using Coulomb's law...

Today Phil explores the world of tides! What is the relationship between tides and gravity? How do planets and their moons become tidally locked? What would happen if you were 300km tall? Important questions.

Jessi and Squeaks found a ton of rocks for their rock collection... but they're too heavy to get back to the fort! Join them as they figure out the perfect simple machine to help them out: the wheel and axle!

In this video Paul Andersen explains cause and effect its importance in science and engineering. He starts by addressing the chain of interactions that must be present to show cause and effect. He addresses the assumptions of...

In this video Paul Andersen explains how the quantum mechanical model of the atom refined the shell model. Uncertainty of the position of the electron as well as spin forces chemists to create an improved model. In this model the...

New ReviewImagine a world where Earth stops spinning—oceans drift toward the poles, leaving behind a vast equatorial continent encircling the planet like a belt.

New ReviewWatch it spin through the air!

Jump into action with our "Get Moving Song"! Perfect for kids, this catchy tune will spark your energy and teach you all about the wonders of staying active and healthy.

A horseshoe vortex cloud is an odd kind of cumulus cloud that is usually small and brief, so it goes unnoticed. It’s shaped like a horseshoe. Some sort of up and down air motion or spin in the air, known as a vortex, creates these, but...
