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 ...

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 ...

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 ...

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 ...

A team of scientists has found that the narrow beam of a laser, under specific conditions, can cast a shadow — a counterintuitive finding that could open the doors for new applications of optical ...

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 ...

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,” ...
