The internal structure of a proton, with quarks, gluons, and quark spin shown. The nuclear force acts like a spring, with negligible force when unstretched but large, attractive forces when stretched ...

There’s a pencil lying on my desk right now. It’s not much to look at, but what if I could zoom way in and see the protons and other itty-bitty stuff inside it? My friend Ryan Corbin told me it would ...

Inside the proton are elementary particles called quarks. Quarks and protons have an intrinsic angular momentum called spin. Spin can point in different directions. When it is perpendicular to the ...

Nature is the ultimate puzzle player, as scientists at the European Center for Nuclear Research (CERN) found out last week. In the late 1950s, particle physics was in crisis. Being the branch of ...

Nuclear physicists may have finally pinpointed where in the proton a large fraction of its mass resides. A recent experiment carried out at the U.S. Department of Energy's Thomas Jefferson National ...

Add Yahoo as a preferred source to see more of our stories on Google. For decades, physicists have relied on the principle of symmetry to simplify and understand the complex behaviors of subatomic ...

All the matter we know of in the Universe is made up of Standard Model particles. Photons and neutrinos zip through the Universe all the time, far outnumbering all the other particles. Normal, ...

As they probe deeper into the heart of the atom, discovering ever smaller and more mysterious particles and particles within particles, scientists have succeeded in bringing the once stable world of ...

Probing ever deeper into the inner world of the atom, nuclear physicists have uncovered an increasingly baffling collection of tiny particles. Besides the familiar neutrons, electrons and protons, ...

So there are these things called quarks. (I know, I wish they had a better name, but I'm not in charge of naming things in physics.) Quarks are little teensy tiny particles (we'll get to exactly how ...
