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

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

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

What was discovered: Scientists observed that electron crystals in metals can deform and melt like solids, disrupting their ordered patterns. Why it matters: Manipulating these structures could enable ...

When a laser beam is incident on many small objects such as lycopodium powder, the resulting diffraction pattern is similar to the diffraction pattern of a small circular aperture (Airy's disk pattern ...

The (relatively) ancient art of crystallography has had a huge impact on modern science by showing us the location of atoms within a molecule. The structure of DNA (and how it acts as an information ...

Nobody knows what the surface of neutron stars are made of but there’s no shortage of suggestions. We know that iron must play a role because we can see its characteristics absorption lines in the ...

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 ...
