Astronomers have gotten pretty good at calculating how fast the universe is expanding, but new measurements don’t line up with the predictions of well-tested laws of physics. Now scientists have a new question to ponder: Why are these...

A look at what turbulence is (in fluid flow), and a result by Kolmogorov regarding the energy cascade of turbulence.

A visual for derivatives which generalizes more nicely to topics beyond calculus. Thinking of a function as a transformation, the derivative measure how much that function locally stretches or squishes a given region.

Hank describes to us some news stories that illustrate how science is continually changing the things we think we "know" - from the status of various animals species, to the way our senses work and even where the Moon came from -...

Computer models are helping scientists on the hunt for small black holes and new data is giving us a better understanding of the universe’s largest explosions.

In the 1950s, the discovery of two new drugs sparked what would become a multi-billion dollar market for antidepressants. Neither drug was intended to treat depression at all— many doctors and scientists believed psychotherapy was the...

Hidden truths permeate our world; they're inaccessible to our senses, but math allows us to go beyond our intuition to uncover their mysteries. In this survey of mathematical breakthroughs, Fields Medal winner Cedric Villani speaks to...

Neutrinos are weird. But all the big unsolved problems in physics are somehow connected to one unsolved mystery: Why do neutrinos have mass?

Not all animals have a mouth, or even need one to eat! These different feeding strategies can teach us a lot about our ancestors and how they went from not needing a mouth at all to only eating with one.

In this video, we discuss the reports about the detection of a pair of supermassive black holes orbiting only one light year apart from each other. Studying the dance of these giants should tell us a ton about how black holes grow.

After visiting all 50 US states to talk to people about racial literacy, Winona Guo and Priya Vulchi expected to hear personal stories of race, culture and intersectionality; what they weren't expecting was how their unique upbringing...

We pretty much know for sure that the universe was once extremely small, and extremely hot. And we know that something set it in motion, expanding rapidly and continuing to do-so today. But the actual moment of 'the Big Bang' is still a...

It’s easy to imagine that our galaxy is basically frozen in time from the perspective of a human lifespan, but in fact, the Milky Way is incredibly dynamic and will undergo some pretty amazing changes in only a few decades!

In honor of October 13th, International Skeptics Day, Hank has put together this playlist of some of the most interesting science-y, skeptic-y videos from all around YouTube.

What makes work satisfying? Apart from a paycheck, there are intangible values that, Barry Schwartz suggests, our current way of thinking about work simply ignores. It's time to stop thinking of workers as cogs on a wheel.

A visual for derivatives which generalizes more nicely to topics beyond calculus.

The determinant has a very natural visual intuition, even though it's formula can make it seem more complicated than it really is.

Science can help create understanding where there is none, but is it possible to study and understand terrorists if we're too busy doing everything we can to stop it? Terrorism is notoriously difficult to study because governments...

On earth it rains water, on the exoplanet WASP-76b, it rains liquid iron, but no matter what planet you're on, the rain drops there have a lot more in common than you might think.

Some fish have superpowers! Zebrafish eyes can boost the color and contrast of what they see and baby whale fish are electric.

Can Twitter be saved? In a wide-ranging conversation with TED's Chris Anderson and Whitney Pennington Rodgers, Twitter CEO Jack Dorsey discusses the future of the platform -- acknowledging problems with harassment and moderation and...

TED Fellow and astronomer Erika Hamden leads the team building FIREBall, a telescope that hangs from a giant balloon at the very edge of space and looks for clues about how stars are created. She takes us inside the roller-coaster,...

Imagine you were asked to invent something new. It could be whatever you want, made from anything you choose, in any shape or size. That kind of creative freedom sounds so liberating, doesn't it?
