Researchers discover why atoms in solids show a preference for certain structures
(PhysOrg.com) -- Nature likes some symmetries, but dislikes others. Ordered solids often display a so-called 6-fold rotation symmetry. To achieve this kind of symmetry, the atoms in a plane surround themselves with six neighbours ...

Photons led astray: Investigating the random motion of quantum particles
(PhysOrg.com) -- Life would sometimes be so much easier if we were quantum particles. For example, if we were trying to find our way out of a strange town allowing chance telling us which way to go at every intersection. ...
