When you’re learning about science for the first time, it can be easier to break things down into a simpler form, and you can end up with a few misconceptions about the world. But sometimes this is the first step to understanding that...

In which John Green, Hank Green, and Emily Graslie teach you about what happened in the Universe after the big bang. They'll teach you about cosmic background radiation, how a bunch of hydrogen and helium turned into stars, formed...

Our universe started with the Big Bang, but how will it end? Explore cosmologists’ three possible scenarios: the Big Crunch, the Big Freeze and the Big Rip. -- We know about our universe’s past: the Big Bang theory predicts that all...

In this video Paul Andersen explains how a system can be viewed as an object and an object can be viewed as a system.

At the beginning of the 20th century, many scientists thought that we had learned all there was to know about physics. The problem is, the better we get at measuring things and building models of our universe, the more we discover that...

As the year 1905 began, Albert Einstein faced life as a "failed" academic. Yet within the next twelve months, he would publish four extraordinary papers, each on a different topic, that were destined to radically transform our...

In this video Paul Andersen shows conceptual thinking in a mini-lesson on matter and matter transport.

Scientists have been searching for alien life by honing in on the existence of liquid water, but we might be overlooking some types of life out there that doesn't need water at all.

The universe is made up of information, similar to a computer, and physics (you know, the basis of the universe) certainly is based on computational principles. But is it running some grand program? Will the answer be 42? Make sure you...

If you want to make atoms THIS cold, you can’t just stick them in the freezer…you’ll need to take advantage of quantum mechanics!

Things get weird under pressure.

As Earth’s climate changes, one of the hardest things to figure out is exactly how the planet will change in response. And while we can’t know the future for sure, we can get a lot of good clues from the past.

Hank responds to viewer questions, and explains what the Higgs boson particle actually IS.

We’ve developed thousands of technologies for space exploration, but luckily for us, sometimes those solutions apply to problems here on the ground, too.

Whether it's robots under the sea, wave detectors in space, or star-power on land, this episode has big experiments covered.

The tiny atoms that make up our world are made up of even tinier protons, neutrons and electrons. Though the number of protons determines an atom's identity, it's the electrons -- specifically, their exact location outside the nucleus --...

SciShow’s Executive producer Hank Green faces off against SciShow senior editor Alyssa Lerner in this Quiz Show about weird experiments and strange animal parts.

Nuclear weapons are the most destructive things we’ve ever created, but it turns out there’s a way to make them even deadlier…

The sun shapes the solar system in many ways, including through its mysterious solar wind, which was thought to be pushed through the force of the sun’s electric field. Recent observations revealed, though, that that hypothesis may not...

The Greeks had a simple and elegant formula for the universe: just earth, fire, wind, and water. Turns out there's more to it than that -- a lot more. Visible matter (and that goes beyond the four Greek elements) comprises only 4% of the...

Elementary particles are the smallest known building blocks in the universe-and the neutrino is one of the smallest of the small. These tiny neutrinos can tell us about the furthest reaches and most extreme environments of the universe...

Is teleportation possible? Could a baseball transform into something like a radio wave, travel through buildings, bounce around corners, and change back into a baseball? Oddly enough, thanks to quantum mechanics, the answer might...

In this episode of Crash Course Chemistry, Hank discusses what Molecules actually look like and why, some quantum-mechanical three dimensional wave functions are explored, he touches on hybridization, and delves into sigma and pi...

JoAnn Kuchera-Morin demos the AlloSphere, a new way to see, hear and interpret scientific data. Dive into the brain, feel electron spin, hear the music of the elements ... and detect previously unseen patterns that could lead to new...
