Matter-wave interference. Nanomechanical answer to Einstein

Quantum mechanical wave interference of massive molecules at an atomically thin grating sheds new light on an old question

The making of the standard model

The standard model of particle physics is more than a model. It is a detailed theory that encompasses nearly all that is known about the subatomic particles and forces in a concise set of principles and equations. The extensive research that culminated in this model includes numerous small and large triumphs. Extremely delicate experiments, as well as tedious theoretical calculations — demanding the utmost of human ingenuity — have been essential to achieve this success
