You can’t understand light without also knowing darkness. It’s like you can’t understand true happiness unless you also experience sadness. The best design comes when there’s a balance between light ...

In a discovery that challenges conventional optics, scientists have managed to make a laser beam cast its own shadow—a feat previously thought impossible, as light typically passes through other light ...

After sifting through possible names for this blog, I settled on Light and Shadow—not Light and Darkness, not Black and White. My first entry, “Surprised by the Light: Lessons from a Junkyard,” ...

For the experiment, a high-power green laser was directed through ruby cube and illuminated with a blue laser from the side. The green laser increases the optical absorption of the blue illuminating ...

Bruce Handy, Lisk Feng and Cat Min present shadows for what they are: the non-nefarious interplay of light and dark. By Leigh Ann Henion Leigh Ann Henion is the author of “Phenomenal: A Hesitant ...

Today, I'd like to dive into the use of shadows in landscape photography. Shadows are almost always part of nature: we often shoot using a (almost-)point light source (the sun or the moon), and even ...

A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. It turns out that if you manipulate a laser just right, then hit it side-on with another ...

Researchers have found that under certain conditions, a laser beam can act like an opaque object and cast a shadow, opening new possibilities for technologies that could use a laser beam to control ...
