I’ve tested a collection of flashlights over the last year by using them for EDC, around the house, and while hunting and fishing. I also collected beam comparison photos to help you find the right ...

Scientists in Florence have built a device that allows them to study quantum and classical physics side by side. Using ...

There’s just something about the “pew-pew” factor that makes projecting a laser beam fun, even if it’s not the safest thing to do, or the most efficient way to the light from one place to ...

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 ...
