The predicted diffraction pattern for Auger electrons emitted from a recoiling oxygen molecule (left) and the pattern measured at SOLEIL. When a measurement reveals which atoms emit successive ...

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 ...

One of the coolest things about physics is that the same basic concept can pop up in several seemingly unrelated things: say, a CD, the seed shrimp’s antennae, certain fossils in the Burgess shale, ...
