Once a baffling theory, quantum mechanics has evolved into a driving force behind modern technology and frontier research.

Physicists have achieved a long-sought goal in demonstrating quantum entanglement using the momentum of atoms, rather than ...

The new baryon “Xi-cc-plus” decays into other particles almost instantly, but its existence could paint a clearer picture on a subatomic subject.

The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

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 ...

Almost anything is possible — at least for a subatomic particle. One of the many mystifying consequences of quantum mechanics — the rules that govern the behavior of tiny subatomic particles — is that ...

Add Yahoo as a preferred source to see more of our stories on Google. Scientists imagine virtual particles popping in and out of existence to explain how forces transfer between particles.

When most of us picture an atom, we think about a small nucleus made of protons and neutrons orbited by one or more electrons. We view these electrons as point-like while rapidly orbiting the nucleus.

While the world's largest atom smasher was busy finding the Higgs boson — the particle thought to explain why other particles have mass — physicists have been quietly building giant laboratories deep ...
