Saturn’s rings, colored photography, and the discovery of electromagnetic waves all have have one thing in common. James Clerk Maxwell. Discover for yourself all the amazing contributions Maxwell made to science.

When you imagine the energy of the future, solar power is probably in the picture – but in recent years, less than 2% of the world’s electricity has come from solar power. Here are 5 new inventions that are likely to change that.

Although coal is such an amazing energy source that we've kept using it despite the harm it causes, today we may be better poised to stop using it than at any previous time in history.

Modern computers are revolutionizing our lives, performing tasks unimaginable only decades ago. This was made possible by a long series of innovations, but there's one foundational invention that almost everything else relies upon: the...

In today’s episode we’ll explore thermodynamics and some of the ways it shows up in our daily lives. We’ll learn the zeroth law of thermodynamics, what it means to reach a thermal equilibrium, and define the first law of thermodynamics....

Lighting up the TED stage, Nobel laureate Al Gore takes stock of the current state of climate progress and calls attention to institutions that have failed to honor their promises by continuing to pour money into polluting sectors. He...

From a blacksmith's son, to one of the most repeated names in physics textbooks, Michael Faraday epitomized the spirit of scientific exploration

In this video Paul Andersen explains how thermal conductivity measures the ability of material to transfer heat from a hot to a cold object. The thermal conductivity of conductors is high because the heat travels through the delocalized...

Most of the cases we call “electrocutions” are actually electric shocks: an electric current running through a body. Whether an electric shock becomes an electrocution depends on the nature of the current involved.

Biology and technology grew closer together when scientists manufactured neurons that acted like those in a brain! And birds evolved to protect themselves in two ways: fight and flight.

Africa’s Sahara desert is a prime location, some say, to build arrays of solar panels and wind turbines. But scientists are aware that building these structures can potentially have large-scale effects on the surrounding environment that...

Ever wonder how lightning works? Scientists are still figuring it out, but what we do know is fascinating. Learn about positive and negative lightning, red sprites, blue jets, and ball lightning in this episode of SciShow!

Hank shows us another SciShow: Experiment! This time he's tackling what may be the most cliche, well-known and misunderstood experiment of all time: the lemon battery. The take home message in this one is: the electricity is NOT in the...

Cycles are a big deal in engineering. Today we’ll explain what they are and how they’re used in heat engines, refrigerators, and heat pumps. We’ll also discuss phase diagrams and the power of using renewable energy resources

In this video Paul Andersen explains how resistors and capacitors affect circuits. The resistance of a resistor is affected by the resistivity of the material and the geometry of the resistor. The current through a resistor can be...

Historians love to debate each other. So some of them pointed out that the first half of this revolution looks a lot different from the second. Let's chat about industry, cars, and Henry Ford.

Get to know plasma, the most common, but probably least understood, phase of matter in the universe!

If you haven't heard of it before, you have now. And it may prove to be the next big thing in materials science. SciShow explains what it is, why it's so awesome, and what challenges we face in harnessing its amazing properties.

Hank tells us about new research into the question of how animals navigate from place to place - while the problem is still unresolved, we do have some hypotheses, and they all involve something called "magnetoreception."

You’re probably familiar with the basics of magnets already: They have a north pole and a south pole. Two of the same pole will repel each other, while opposites attract. Only certain materials, especially those that contain iron, can be...

How DO you make a digital clock?

Meet the "Row-bot," a robot that cleans up pollution and generates the electricity needed to power itself by swallowing dirty water. Roboticist Jonathan Rossiter explains how this special swimming machine, which uses a microbial fuel...

Humans have an almost insatiable energy demand, so scientists and engineers are always on the lookout for sustainable ways to provide the energy we need. And some of these ideas go way beyond solar panels and wind turbines! Chapters View...

In 2018, a single power plant produced more energy than the world's largest coal-powered and gas-powered plants combined. China's Three Gorges Dam relies on running water, and is capable of producing more energy than any other power...
