The weak nuclear force doesn't play by the normal rules — and, in fact, it breaks one of the biggest rules of all.

When high-energy radiation interacts with water in living organisms, it generates particles and slow-moving electrons that ...

Static electricity works because electrons are strongly attracted to protons, right? But, in atoms, electrons are right there, next to the protons in the nucleus. Why don’t the electrons zip directly ...

I’ve argued ad nauseam that battery-electric propulsion is poorly suited for most full-scale aircraft applications. To deliver a certain amount of power for a certain length of time requires a weight ...

Proceedings of the Royal Society of London. Series A, Mathematical and Physical Sciences The angular distribution of electrons of given energy ejected by ionization of atomic hydrogen is calculated ...

Measuring up: an electron scattering experiment yields a small proton radius. (Courtesy: Jefferson Lab) For nearly a decade the size of the particle that makes up the bulk of the universe’s visible ...

If you expanded an atom to the size of a baseball, what would it look like? And how would the inside look if you sliced it open? The nucleus is the atom’s central core and contains more than 99.9 ...

The world's largest atom smasher has used its accelerator to speed up proton beams for the first time as scientists moved ahead in efforts to learn more about the universe. The $10 billion Large ...

The Chlamydomonas reinhardtii proton gradient regulation5 (Crpgr5) mutant shows phenotypic and functional traits similar to mutants in the Arabidopsis (Arabidopsis thaliana) ortholog, Atpgr5, ...
