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 ...

Christopher Chyba held a hollow, dark cylinder made of manganese, zinc, and iron in his Princeton lab, looking skeptically at ...

Atomic nuclei with “magic numbers” of protons or neutrons in their nuclear shells are extremely stable. Nuclear physicists ...

electromagnetic, strong nuclear, and weak nuclear forces. However, scientists don’t know how gravity fits into quantum mechanics. In fact, they have been proposing experiments that can test the ...
