James Beacham looks for answers to the most important open questions of physics using the biggest science experiment ever mounted, CeRN's Large Hadron Collider. In this fun and accessible talk about how science happens, Beacham takes us...

Hank brings us up to date on the latest in the search for the Higgs boson and interviews Fermilab physicist Rob Roser.

Brains are mysterious! Living brains are particularly tough to study, but sometimes scientists can use techniques from other disciplines to get a clearer picture. Here are some ways scientists are adapting tools developed for looking at...

Stephen Hawking recently announced that he'd come up with an answer to one of the biggest questions in physics. But it'll probably be a while before we know exactly what it is.

This year's end News episode wraps up with nothing but superlatives: the biggest, oldest, first, last, smallest and hottest developments in science from 2012.

The fact that no one knows the answer to this question is what makes it exciting. The story of physics has been one of an ever-expanding understanding of the sheer scale of reality, to the point where physicists are now postulating that...

This video is about weird condensed matter systems, aka materials that have bizarre emergent particles in them that are unlike most other particles in the universe.

With the large hadron collider running out of places to look for clues to a deeper theory of physics, we need a bigger particle accelerator. We have one - the galaxy.

Why is there something rather than nothing? Why does so much interesting stuff exist in the universe? Particle physicist Harry Cliff works on the Large Hadron Collider at CERN, and he has some potentially bad news for people who seek...

The Heisenberg Uncertainty Principle might not mean what you think it means: Hank clears things up for us in this edition of IDTIMWYTIM, by distinguishing between the Uncertainty Principle and the Observer Effect, which are often conflated.

Our fundamental picture of the universe seems pretty nearly complete these days, to the point that some people are suggesting that we’ve arrived at some version of “the end of physics.” And sure, physics is at a turning point, but it...

So, a mantis shrimp's claws are pretty strong... so strong that they can produce a bubble that's about as hot as the sun and collapses with a flash of light when they snap... and scientists aren't quite sure how they do it!

There’s a massive black hole next door that appears far too big for its host galaxy! And in another galaxy, TWO supermassive black holes formed, giving us a glimpse at a true rarity in astronomy!

This week, CERN announced a new particle that will help further understanding of the fundamental forces, and a simulation of ancient creatures may give us a clue as to how life grew beyond the microscopic.

Quantum field theory is notoriously complicated, built from mind-bendingly abstract mathematics. But are the underlying rules of reality really so far from human intuition? Or are physicists just showing off? For better or worse, the...

Diffuse interstellar bands were first discovered in 1919 and since then scientists have found nearly 500 of them. How many do we understand? Only one.

This video is about gravitational waves in the weak field limit as discovered by the LIGO collaboration, explained by parallels to electromagnetic radiation, sound waves, water waves, etc. I want to see Cat LIGO ASAP!

Hank gets to the bottom of this "faster-than-the-speed-of-light-neutrino" kerfuffle, discusses some ancient stuff, and announces the winner of the award for worst science in a film

Quantum mechanics is weird and seems a bit...complicated. But understanding it can help us to understand the universe.

Making a black hole in a particle accelerator sounds… a bit dangerous, to say the least, but scientists think that it could be possible! Here's why it probably wouldn't be dangerous -- and might even teach us something.

Although science has provided astounding insights into the origins of the universe, we're still not quite sure what happened in those very first few moments.

In this, THE FIRST EPISODE of Crash Course Physics, your host Dr. Shini Somara introduces us to the ideas of motion in a straight line. She talks about displacement, acceleration, time, velocity, and the definition of acceleration. Also,...

When you think about archaeology, space technology probably isn’t the first thing that comes to mind. But from satellites to cosmic rays, archaeologists actually look to space a lot more than you might think!

Some of the greatest advances in science have come from humanity's more destructive impulses. This is not the fault of science - when we discover powerful truths about the universe it's up to us to decide how to use them because...
