This turned out to be far too small an effect to see, but it gave us the motivation to study the exact nature of optical reflection. The general motivation for investigating the effect at shorter ...

Particle physics is the study of the elementary building blocks of matter and radiation and their interaction. The fundamental particles are summarised by the standard model. This includes leptons ...

Physicists at the Fermi National Accelerator Laboratory have found more evidence that a subatomic particle is behaving unexpectedly. And the reason could be evidence of a new, fifth force of nature.
