A doctoral student at the University of Cambridge has come up with a possible explanation for the westward drift of the Earth's magnetic field. In his paper published in Proceedings of the Royal Society A, O.P. Bardsley suggests ...
The movement of thousands of electrons underlies electronics. Yet, ubiquitous as electrons are, the particulars of their behavior continue to stump physicists. One phenomenon has proven especially puzzling: how electrons ...
