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 ...

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 ...

Artist’s depiction of the spray of particles arising from the collision of two heavy atoms. As the hot subatomic soup cools, newly formed particles shower off into space. This finding improves ...

Amid the many mysteries of quantum physics, subatomic particles don't always follow the rules of the physical world. They can exist in two places at once, pass through solid barriers and even ...

His research enabled the discovery that protons and neutrons are made of smaller particles, contributing to a fuller picture of the subatomic universe. By Katrina Miller Katrina Miller earned a Ph.D.

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 ...
