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.


Inventors Of The Blue LED Inside Nearly Every Device You Own Win Nobel Prize

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 scientists who made this revolutionary discovery.


Beautiful Glass Sculptures Transform Light Into Beautiful Colour Shapes

Chris Wood loves glass. So much she’s dedicating her life to the study of its properties, creating these beautiful installations in which light and colour become a quasi-three-dimensional object.


This Rube Goldberg Machine Is Powered By Light

Video: 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.


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 light per pixel.


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.


Why Deer Freeze In Your Headlights

Less a function of fear than bewilderment; simply put, deer freeze in headlights because they can’t see.


Why Is The Speed Of Darkness Faster Than The Speed Of Light?

Video: 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.


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 our offices to show us the light.


How NASA Uses The Full Moon To Calibrate Its Earth-Gazing Satellite

The full moon — like this weekend’s glorious Super Moon event — is a great show for us here on Earth. But for NASA, it also plays a critical role in keeping its Landsat 8 satellite working properly. How? By using the moon exactly like a photographer uses a light meter.
