A device made using a tiny bead floating in a beam of light can measure extremely small pressures and could help find a mysterious kind of neutrino Most people think the multiverse is just about "what ...

A weird force that skirts traditional physics norms has helped erase a smudge on the foundations of particle physics. It’s a phenomenon called the “neutrino force,” by which neutrinos could ...

Theoretical particle physics is the development of models for describing fundamental particles and their interactions. This includes testing and refining the prevailing theory: the standard model.

Experimental particle physics is the practical investigation of the fundamental components of matter and radiation. A crucial tool in the arsenal of the experimental particle physicist is the particle ...

Matter is made up of small particles called atoms. Atoms can exist on their own or together as molecules. Atoms are very small and around 100,000,000 of them end to end would measure 1 centimetre.

Solids, liquids and gases change state when they are heated or cooled. Processes such as evaporation and boiling change the state of substances. A particle model can be used to show how solids, ...

After 25 years, Brookhaven National Laboratory’s Relativistic Heavy Ion Collider—the U.S.’s largest and only particle collider—has ceased operations, but its science lives on ...
