Physics is most readily applied to relatively simple systems: a pendulum, two electrons colliding or the structure of the ...

Physicists at Cern have discovered a plethora of new exotic particles being created in the collisions produced by the Large Hadron Collider over the past few years. So many have been found, in fact, ...

An electron is supposed to be indivisible. It carries one fundamental unit of electric charge, and every electron is exactly ...

Physicists have taken a first step in understanding quantum emergence -- the transition from 'one-to-many' particles -- by studying not one, not many, but two isolated, interacting particles. The ...

They're called ghost particles for a reason. They're everywhere—trillions of them constantly stream through everything: our bodies, our planet, even the entire cosmos. These so-called neutrinos are ...

Every time I write about particle physics, I encounter a moment of uncertainty about a quantity that, at first glance, ought to be clear. How many kinds of elementary particles should I say there are?
