This lesson utilizes an adaptation of the board game Subatomic: An Atom Building Game to help students learn about the different parts that make up an atom. During their turn, players can choose to ...

New research has found that protons are about 20 times more likely to pair up with neutrons than with other protons in the nucleus. The result, based on the first-ever simultaneous measurement of such ...

Inside each proton or neutron there are three quarks bound by gluons. Until now, it has often been assumed that two of them form a "stable" pair known as a diquark. It seems, however, that it's the ...

The “lead” of a pencil is actually made of a substance called graphite which is made of carbon atoms. The picture shows a close-up of one carbon atom. A hydrogen atom has one proton as the nucleus and ...

If you hit an atom’s nucleus hard enough, it will fall apart. But exactly how it falls apart tells us something about the internal structure of the nucleus and perhaps about the interior of neutron ...

The structure of a neutron or a proton is modified when the particle is bound in an atomic nucleus. Experimental data suggest an explanation for this phenomenon that could have broad implications for ...

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 ...

OAK RIDGE, Tenn. — Examining the smallest parts of the universe often takes the biggest kinds of equipment. At Oak Ridge National Laboratory, a unique piece of equipment the size of a building is ...

According to the classical model of nuclear structure, the internal structure of nucleons should not change if they are bound into atomic nuclei. But it was discovered 35 years ago that quarks inside ...

Atoms are made of three things: protons, neutrons, and electrons. Electrons are a type of fundamental particle, but protons and neutrons are composite particles made of up and down quarks. Protons ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. If you want to probe the frontiers of fundamental physics, you have to ...
