Getting older means it’s likely that your eyes will have trouble focusing on things at close distances, so we are often prescribed glasses to combat this problem. But what if there were eye drops that could achieve the same results? <br/>

What is integration? Why is it computed as the opposite of differentiation? What is the fundamental theorem of calculus?

In November 1986, Australian miners climbed Lunatic Hill and bored 20 meters into the Earth. They were rewarded with a fist-sized, record breaking gemstone, which they named the Hailey's Comet opal. Thanks to a characteristic called...

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

How to See Without Glasses

Earlier this spring NASA announced a new research model that predicts that ocean worlds are far from rare, and our galaxy might be full of them. And a new study examines evidence that Pluto may have had an underground ocean all along!

On this Space Time Journal Club we look at how gravitational waves can be used to search for extra dimensions of space!

Today, we're going to talk about how the Earth moves, but to do that, we're going to have to go way back to the early days of the galaxy! Processes that happened before the Earth even formed have led us to the geographic patterns and...

There are exoplanets out there that seem very Earth-like, but if you look out and see liquid metal instead of liquid water, you might be in the Venus zone.

To hopefully put your mind more at ease, Hank is here to talk about the work that goes into designing and building ICBMs.

Eric Giler wants to untangle our wired lives with cable-free electric power. Here, he covers what this sci-fi tech offers, and demos MIT's breakthrough version, WiTricity -- a near-to-market invention that may soon recharge your cell...

When you think about Einstein and physics, E=mc^2 is probably the first thing that comes to mind. But one of his greatest contributions to the field actually came in the form of an odd philosophical footnote in a 1935 paper he co-wrote...

An introduction to what a derivative is, and how it formalizes an otherwise paradoxical idea.

The Gaia space observatory released a detailed 3d map of the Milky Way, and scientists have figured out why Charon's north pole is red!

2016 was a lot of things, but for astronomers, it meant the discovery of some of the farthest, faintest, and youngest objects in the universe we've seen yet.

Last week, seven earth-like planets were discovered orbiting a Red Dwarf star 39 light years away. Each one could be capable of supporting life.

If you've been wondering why we have butts, wonder no more! We have an answer for you.

The newest 8K TVs have 33 million pixels - but can you even see that many?

These little fliers may be small, but pound for pound, they go farther than just about anyone else.

Considering how massive our universe is, we know the distances to cosmic objects surprisingly well. What tools and clues do scientists use to measure distances that are so enormous they sound like made-up numbers?

Solar tornadoes are not tornadoes, and scientists are studying a black hole with a telescope bigger than the earth!

What is integration? Why is it computed as the opposite of differentiation? What is the fundamental theorem of calculus?

An ancient, abandoned alien space station has been discovered. Can you beat everyone in the galaxy and reach it first? -- It’s an incredible discovery: an abandoned alien space station filled with precursor technology. Now every...

This video is chapter 5 in my series on special relativity, and it covers how things that are moving (that is, moving relative to an inertial reference frame) at different speeds appear to be shorter in length... and longer in...
