Instead of a boring slide deck at your next presentation, how about bringing in a troupe of dancers? That's science writer John Bohannon's "modest proposal" in this spellbinding choreographed talk. He makes his case by example, in...

Underneath every shiny new megacity, there's often a story of communities displaced. In this moving, poetic talk, OluTimehin Adegbeye details how government land grabs are destroying the lives of thousands who live in the coastal...

Some of the universe's biggest action is a result of its smallest stuff

Can you make a black hole out of light? Learn about the strange theoretical object called the 'Kugelblitz'.

A billion people in the world lack access to all-season roads. Could the structure of the internet provide a model for how to reach them? Andreas Raptopoulos of Matternet thinks so. He introduces a new type of transportation system that...

Hank gives us an inclusive overview of how everything in the universe is thought to have begun, and how cosmologists predict it will all come to an end. Now get happy!

It’s an election year, which means you’ve probably been bombarded with polls asking you questions about candidates and issues. But is information the only thing pollsters are after? Questions are often more than just questions. They can...

All the stars in a spiral galaxy rotate around a center -- but to astronomers, the speed that each star travels wasn't making sense. Why didn't stars slow down toward the edges as expected? Don Lincoln explains how a mysterious force...

SciShow Space reveals the discovery of a whole new kind of supernova, and the undead stars they leave behind.

In this video Paul Andersen shows conceptual thinking in a mini-lesson on the conservation of matter.


TERMS
Matter - physical
substances
Atoms - the basic un
it of elements
Conservation - the quantity of a...

Roughly 85 percent of mass in the universe is "dark matter" -- mysterious material that can't be directly observed but has an immense influence on the cosmos. What exactly is this strange stuff, and what does it have to do with our...

Author and activist Isabel Allende discusses women, creativity, the definition of feminism -- and, of course, passion -- in this talk.

Our laws of physics are equations of motion, along with some associated constants. We've talked about the symmetries of these equations, and how they lead us to conserved quantities. But this is just the tip of the theoretical iceberg -...

Rovers like Curiosity search for life on Mars using rock and soil samples, but why don't they examine liquid or frozen water?

A paper published last week proposed a hypothesis that identified 95% of the missing stuff in the universe, but the headlines have been a little over-hyped.

Astronomers might have finally discovered part of why Tabby's Star acts so strangely and we have some new ideas about what triggers a type Ia supernova.

Daniel Goleman, author of "Emotional Intelligence," asks why we aren't more compassionate more of the time.

Hank explains the science behind recent reports that physics great Stephen Hawking said "there are no black holes." There are. They're just super complicated.

Scientists picked up two unusual signals that seemed to be coming up from the ground instead of down from space. They're still working on understanding why, but despite what you may have heard, they aren't evidence for a parallel...

Thanks to the wonders of physics, astronomers can map a timeline of the universe’s history. Today, Phil’s going to give you an overview of those first few minutes (yes, MINUTES) of the universe’s life. It started with a Big Bang, when...

Imagine you're on a game show and you can choose between two prizes: a diamond - or a bottle of water. It's an easy choice _ the diamonds are more valuable. But if given the same choice when you were dehydrated in the desert, after...

Scientists are still working on theories that might help explain what the vast majority of our universe is made of.

When you imagine a walrus, you probably picture it way smaller than it actually is. It’s because our brains meddle with our senses in more ways than you might expect.

What exactly can we tell about an unknown substance by it's properties. We already know that a substance is matter that’s made of one kind of atom or molecule, and that has specific properties and that some substances are elements, which...
