How gravity causes a perfectly spherical ball to roll down an inclined plane is part of the elementary school physics canon.

With a new measurement imminent, the Courier explores the experimental results and theoretical calculations used to predict ‘muon g-2’ – one of particle physics’ most precisely known quantities and ...

ABSTRACT: Lorentz invariance admits more general definitions for the relativistic momen- tum. In this paper, we study some consequences that follow one such gene- ralization.
