Highly charged heavy ions form a very suitable experimental field for investigating quantum electrodynamics (QED), the ...
American researchers have measured a tiny electrical voltage by exploiting Earth's magnetic field in the planet's rotational motion. This discovery, though modest, revives a scientific debate ...
