Recent scientific advancements have opened new opportunities for the close observation of physical phenomena. Researchers at University of Cambridge and University of Newcastle recently introduced a ...

One of the simplest and most beautiful naturally occurring patterns can be observed when light is shined through a pair of slightly misaligned periodic structures. This phenomenon, known as the moiré ...

The basics of digital logic are pretty easy to master, and figuring out how the ones and zeroes flow through various kinds of gates is often an interesting exercise. Taking things down a level and ...

A variety of ultrathin nanomechanical diffraction gratings that have been fashioned from the “wonder material” graphene have been created by an international team of researchers. The team wanted to ...

What is the Diffraction Limit? The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It ...
