X is everywhere and it’s probably thanks to math. But why is x the symbol for the unknown?

In order to study the smallest particles in the known universe, physicists have to build incredibly huge detectors. One of them, currently under construction, stretches across the Mediterranean from France to Greece. And despite being...

Science offers a way of discovering and understanding the world around us, driven by questions and tested with evidence. And it’s a twisty-turny team effort— you won’t find many lone geniuses out there, or straight lines from hypothesis...

In the desert of Peru, hundreds of enormous ancient drawings are carved into the dirt. They're called the Nazca Lines, and archeologists are still arguing over what they mean. <b<br/>r/>

The people behind the greatest leaps in physics - Einstein, Newton, Heisenberg, all had the uncanny ability to see the fundamentals - see the deepest, underlying facts about the world, and from simple statements about reality they built...

What really killed Mozart?

There are still some great mysteries of our universe that physicists can't explain. How is that possible? Join us as we break down the 4 greatest mysteries of physics in this episode of SciShow hosted by Michael Aranda!

You know how moths like to fly into lamps or crawl all over your tv screen at night? Why do they do this?! The answer is more complicated than you might think...

Nowadays, we're pretty confident about how the dinosaurs died out, but there are still other extinctions throughout Earth's history, some big, some small, that remain unsolved.

Evidence strongly suggests that men have, on average, a shorter lifespan than women, but scientists aren't exactly sure why that is. Check out today's QQ to learn more about this mortality mystery.

I don't mean it mean, but today we're going to be cruel. It's the fun-loving Theater of Cruelty, which was pioneered by the genius Antonin Artaud in France during the inter-war period in twentieth century. The Theater of Cruelty was...

Book: Einstein

Paul Andersen explains how scientists modify theories by constructing explanations. He also discusses the cycle of design used by engineers to solve problems. He starts by defining a theory as a well-established explanation of a...

The history of medicine is about two of our big questions: one, what is life? What makes it so special, so fragile, so… goopy!?

Two, how do we know what we know? Why should I take my doctor’s advice? Why are deep-fried Oreos bad...

Herman Rorschach (no, not the guy from Watchmen) came up with the eponymous tests, but what do they mean? Why are we so fascinated with them despite the division in the world of Psychology? Hank tackles these topics as we take a...

We reference the DSM pretty frequently on SciShow Psych, and for good reason: it’s considered the gold standard for professional mental health diagnosis in the United States, but it was an interesting journey to get there.

Scientists in the nineteenth century discovered a lot about life and matter. But exactly what kind of stuff is the human brain? That one was—and is—tricky.



The brain sciences—with experiments and therapies tied to biological...

Physicists are interested in the big questions like "Where did we come from?" and "What is all this stuff?". But the answers to some of these questions, just lead to more questions.

In which Hank and John Green teach you about life on Earth. They won't be giving advice on how life should be lived, because this is a history series. Instead, they'll teach you about the earliest forms of life on Earth, and some of the...

We begin our unit on ethics with a look at metaethics. Hank explains three forms of moral realism – moral absolutism, and cultural relativism, including the difference between descriptive and normative cultural relativism – and moral...

There was a lot of bad stuff going on in Europe in the 17th century. We've seen wars, plagues, and unrest of all types. But, there is some good news. Huge advances were underway in the scientific community in Europe at this time. In this...

Nowadays, we're pretty confident about how the dinosaurs died out, but there are still other extinctions throughout Earth's history, some big, some small, that remain unsolved.

Even if you're Mel Gibson or Kanye, it's probably best to not wear all of your emotions on your sleeve. In this episode of Crash Course Psychology, Hank talks about these things called "Emotions". What are they? And why do we...

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...
