This dancer in a light suit is totally breaking reality

Damn. This video of a dancer in a light suit is like staring into a future that us humans chained to the present aren't supposed to see. The dancing is fun to watch, of course, but there's something about that black and white light up suit moving in those ways that is just jarring and completely warps my view of… » 3/18/15 11:07pm 3/18/15 11:07pm

Did We Really See Light Acting as a Particle and a Wave at Once?

Several weeks ago, the internet lit up with the colorful image shown above, accompanied by headlines claiming that physicists had accomplished the extraordinary: We'd finally managed to see light as both a particle and a wave at the same time. (Your friends at Giz reported it too.) But...it's not exactly true. » 3/15/15 2:00pm 3/15/15 2:00pm

First Ever Image to Show Light as a Wave and Particle at the Same Time

What you're looking at here is a major breakthrough. The image reveals a property of light that has never been witnessed before by human eyes, though we've long known about it. But at last, thanks in an ingenious imaging experiment, we can now see how light behaves as a wave and a particle at the same time. » 3/02/15 8:00pm 3/02/15 8:00pm

What's the Best Desk Lamp?

We recently outlined the best upgrades for your office, but now it's time to shed some light on the desk lamp situation. Which lamp is most deserving of real estate on your desk? Tell us in the comments. » 2/18/15 3:45pm 2/18/15 3:45pm

Scientists Have Made a Möbius Strip Out of Light for the First Time

While you can twist physical materials into a Möbius strip—to make chairs, tables and even buildings—until now it's been impossible to do the same with light. But researchers from the Max Planck Institute for the Science of Light have changed that. » 1/30/15 3:45am 1/30/15 3:45am

Watch This Reflected Laser Pulse's Entire Flight Path at 20bn FPS

The technology available to image light as it moves through space continues to advance. Recently, we saw a new high-speed camera capture a small pulse reflected from a mirror; now, it's possible to image the entire flight path of a laser as it bounces around a laboratory. » 1/27/15 6:45am 1/27/15 6:45am

Researchers Slow The Speed Of Light As It Travels Through A Vacuum

Normally, light zips through a vacuum at a blazing 186,282 miles per second. But as a new experiment by Scottish physicists has shown, this isn't always necessarily the case. » 1/23/15 10:20pm 1/23/15 10:20pm

Why Objects In the Mirror Are Closer Than They Appear

The passenger-side mirror of every modern car in America bears the same warning: "Objects in mirror are closer than they appear." Ever wondered why? It's no design fault; it's actually a safety feature. » 12/09/14 12:00pm 12/09/14 12:00pm

This High Speed Camera Tracks Light Bouncing Off a Mirror at 100bn FPS

Slow-motion photography is cool and all, but now a team of scientists has decided to use high-speed photography to track light as it travels through space. In this GIF, you're looking at a pulse of light hitting and bouncing off of a mirror. Really. » 12/05/14 4:30am 12/05/14 4:30am

This trick to show how invisible air moves seems like magic

This is called Schlieren optics, a cool technique that allows us to see how invisible air moves. Thanks to the difference of density between hot and cold air, light changes speed, bends, and creates visual distortions. Exactly the same thing that happens in the mirages but captured in a controlled environment. » 11/24/14 9:00pm 11/24/14 9:00pm

How Cathedrals' New Video Makes Light Dance to the Music

This is the video for the Cathedrals' song "Unbound." It's lovely! And the way the light cubes in the background pair up with the music is no accident—there's some really cool tech behind it. » 10/23/14 1:58pm 10/23/14 1:58pm

Inventors of the Blue LED Inside Nearly Every Device You Own Win Nobel

There's pretty good chance you have a piece of this year's physics Nobel prize-winning invention in your pocket. The blue light-emitting diode (LED) is found in the screens of millions of phones as well as our bright, new energy-efficient LED lightbulbs. Today, the Nobel Prize in physics was awarded to the three… » 10/07/14 12:30pm 10/07/14 12:30pm

This Rube Goldberg machine is powered by light

It's always fun to see the chain reaction of Rube Goldberg machines and how one action can cascade into a whole bunch of things happening. This one, from an ad for Japanese technology company au, is particularly cool because it's just powered by light and lens and optics. » 9/11/14 1:01am 9/11/14 1:01am

Physicists Figure Out How to Take Photographs In Near-Total Darkness

Tens of thousands of photons go into making up each pixel in your standard cat photo. That's because existing cameras—even infrared night-vision ones—rely on many, many photons of light to create an image. But now physicists have photographed in almost pitch blackness, where there on average is less than one photon of… » 9/02/14 1:30pm 9/02/14 1:30pm

Why Are Stars Star-Shaped?

Our Sun is spherical, so why is it that other stars look... star-shaped in the night sky? Actually, it's all down to the quirks of light and your (imperfect) eyes. » 8/27/14 3:36am 8/27/14 3:36am

Why is the speed of darkness faster than the speed of light?

Michael Stevens explains why darkness moves faster than light in this new episode of Vsauce. I usually find these explainers interesting because they delve not only into multiple science disciplines but often they touch philosophical questions too. This one really blew my mind. » 7/29/14 7:31pm 7/29/14 7:31pm

This Super-Efficient Lightbulb Uses Tesla Tech for an Incandescent Glow

Despite their inefficiency, old-school incandescent lightbulbs sure did put out a pleasant, natural-looking light. The folks at Finally Light Bulb missed that light, so they brought it back with an efficient, affordable bulb using technology Nikola Tesla once patented. The team visited Gizmodo's NYC office to show us… » 7/24/14 11:39am 7/24/14 11:39am
