Diffraction gratings are curious things. Score a series of equally spaced tiny lines in a surface, and it will cause reflected or transmitted light to bend and separate into its component wavelengths.

One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the observation that matter behaves differently at the smallest scales. A key ...

In recent years, the rapid growth of artificial intelligence and the Internet of Things (IoT) has driven a surge in computational demand. Traditional electronic computing, however, is approaching its ...
