How a spritz of oil from a perfume bottle let scientists measure the…

Can you find the charge of an electron in a spritz of oil? It seems like the subatomic world is too tiny ever to be meaningfully measured. But that's exactly what two scientists did in 1909. Find out how, with a box, a microsocope, a spritz of oil, and a sensitive voltage meter, people figured out the charge of an… » 1/28/12 9:00am 1/28/12 9:00am

What if every electron in the universe was all the same exact particle?

There's an idea that suggests all the universe's electrons are actually one particle forever traveling backwards and forwards in time. It's a simple, elegant idea that solves some of physics's biggest mysteries. There's only one tiny problem. It's complete nonsense. » 1/17/12 2:20pm 1/17/12 2:20pm

What do electrons look like? Now we know.

If you've ever looked at a model of the atom, you'd probably guess that electrons are spherical. But these elementary particles are actually slightly egg-shaped...and proving that could mean trouble for one particular model of subatomic physics. » 5/25/11 5:30pm 5/25/11 5:30pm

Gravity finally starts cooperating with quantum mechanics...maybe

Gravity is usually the arch-nemesis of quantum mechanics, stubbornly refusing to play nice with the forces governing the interactions of subatomic particles. Now we've discovered a rare instance where gravity actually assists quantum interactions, which just might help unify physics. » 11/05/10 12:30pm 11/05/10 12:30pm

The Ultimate Field Guide to Subatomic Particles

Muons, neutrinos, supersymmetric partners, the infamous Higgs boson - with so many different subatomic particles flying about, it's no wonder theoretical physics can be so confusing. That's why we made this (reasonably) simple guide to all the different elementary particles. » 9/16/10 10:44am 9/16/10 10:44am
