Positronium shouldn't last long enough to be interesting. It's an "atom" assembled from an electron and its antimatter twin — ...

In a process analogous to how solids melt into liquids, the electrons in many different metals form crystal-like patterns ...

Quantum physics once shocked scientists by revealing that particles can behave like waves—and now, that strange behavior has ...

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

In the field of scanning electron microscopy (SEM), the electron backscatter diffraction (EBSD) method has developed into a robust tool for the crystallographic analysis of materials. Specifically, ...

For the first time, researchers directly characterized the 3D atomic structure of a relaxor ferroelectric, a class of ...

A pattern of distorted lines is visible as a reflection in this close-up view of a human eye. By observing the deformation of illumination patterns reflected off the eye's surface, researchers in ...

This page contains hints, solutions, and advanced challenges for our diffraction grating challenge. If you would like a grating (or a set for your class if you are a teacher), please contact us at ...
