Physicists in Japan have, for the first time, observed quantum interference in a beam of positronium — a short-lived atom made of an electron and its antimatter twin, the positron. The experiment ...

Q: What are diffraction gratings? A diffraction grating is an optical component for spectroscopy that splits light into different wavelengths. A typical diffraction grating has thousands of grooves ...

A long-standing mystery in materials science is beginning to unravel as researchers directly probe the hidden atomic ...

Before trinitite, the only known naturally formed quasicrystal came from meteorite fragments, likely produced during a ...

When we taught a class of first year chem/biochem majors about spectroscopy, we introduced them to it with a task. It was to dig through bins full of the things shown below (many of them 3D-printed ...
