The standard model of particle physics represents the most comprehensive theory about fundamental or subatomic particles and forces in the universe. The model describes how matter and antimatter ...

Researchers created a gas that doesn’t experience resistance or diffusion when cooled to freezing, proving it’s possible for ...

The first-known observations of matter–antimatter asymmetry in a decaying composite subatomic particle that belongs to the baryon class are reported from the LHCb experiment located at the Large ...

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 ...

What is everything made of? It’s the fundamental question that lies at the heart of particle physics. Today, scientists are using gigantic, atom-smashing particle accelerators to probe deeper into the ...

In massive particle accelerators, sub-atomic particles (like electrons) are sped up to super-high speeds comparable to the speed of light towards a target surface. The collision of accelerated ...

One hundred years ago, physicists including Max Born, Niels Bohr, Werner Heisenberg, and Erwin Schrödinger theorized the foundations of quantum mechanics, unlocking atomic and subatomic secrets, ...

The nucleus of an atom is now the modern version of sand flowing through an hourglass. Researchers have spent 15 years trying to increase accuracy in timekeeping. The U.S. standard currently relies on ...
