Tin, a material whose name is sometimes synonymous with "dull," has a secret side that's extraordinary, physicists say. Scientists have succeeded in creating a new type of tin atom with "magic" ...

Quantum electrodynamics (QED) is the fundamental theory describing all electromagnetic phenomena including light (photons). At the same time, it is the most precisely tested theory in physics at all.

Can scientists image the motion of electrons inside atoms? It’s a challenging problem, but solving it would help us develop a more complete understanding of things like chemical reactions and the ...

Atoms are very small. They have a radius of around 1 × 10 10 metres. This symbol shows that chlorine has 35 particles in the nucleus (protons and neutrons), 17 of which are protons. It also tells us ...

This photo shows an experiment at GSI Helmholtz Centre for Heavy Ion Research in Darmstadt, Germany, where 105 liquid nitrogen-cooled gamma ray detectors observed new 'doubly-magic' tin atoms in a ...
