We’ve seen just about every possible way to make a clock here at Hackaday over the years. So it’s rare to have a first, but here we are with [Twisted & Tinned], who’s made a novel clock with a ...

In this video I talk about diffraction gratings and how they work. I show you how you can use them to make diffraction patterns on chocolate or other shiny materials. Trump faces backlash over Coast ...

Scientists have unveiled a new approach to ultra-secure communication that could make quantum encryption simpler and more efficient than ever before. By harnessing a 19th-century optics phenomenon ...

An artistic view of the subwavelength grating made of layered molybdenum diselenide. The red spheres represent molybdenum atoms, and the blue ones represent selenium atoms. Light is trapped within the ...

In Qing dynasty China, artisans augmented decorative pieces by incorporating iridescent kingfisher feathers—a technique known as tian-tsui. Scientists at Northwestern University’s Center for ...

This article evaluates some of the strengths and weaknesses of reflective and diffractive waveguides used in augmented reality (AR) optics for smart glasses. Waveguides are the optics used in smart ...
