Clever Short Film Is Made Completely With Light Paintings

Video: Light painting is usually used to snazz up still photographs in an awesome ‘how they do that’ kind of way but this is even cooler. Darren Pearson made this entire video of moving light paintings by hand drawing over 1000 light paintings and capturing them with long exposure at night to create the effect as if the light was alive and characters in a movie.


Colour -- Not Just Light -- May Affect Our Body Clock

It’s well-known that our body responds to light and dark to help set its circadian rhythms. But new research suggests that our bodies may also respond to colour in order to keep internal time.


Tech Startup Aims For 52-Megapixel Cameras In Phones By 2016

I think we can all agree that the situation with cameras and megapixels has reached maddening heights. DSLRs are expected to have insane resolutions, but mobile phones? No one was really asking for 50+ MP shooters in their iPhones and Galaxys by the end of 2016, but it’s looking possible thanks to a new startup called Light.


You Need To Spend More Time In The Dark To Sleep Better

Today most people do not get enough sleep. The Centers for Disease Control and Prevention (CDC) has called insufficient sleep an epidemic. While we are finally paying attention to the importance of sleep, the need for dark is still mostly ignored.


These Light-Emitting Fibres Could Make Fabrics That Glow

A team of researchers has developed a new light-emitting fibre than could be woven into fabrics, providing flexible smart fabrics than can illuminate themselves.


Did We Really See Light Acting As A Particle And A Wave At Once?

Several weeks ago, the internet lit up with the colourful 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. But…this isn’t exactly true.


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.


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.


Watch This Reflected Laser Pulse's Entire Flight Path At 20 Billion 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.


Giz Explains: Why Objects In The Mirror Are Closer Than They Appear

The passenger-side mirror of every modern car 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.
