For decades, physicists have relied on the principle of symmetry to simplify and understand the complex behaviors of subatomic particles. Symmetry in physics basically means that some rules of nature ...

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.

Fundamental particles called quarks can be created in quantum-correlated pairs. These correlations can be passed on to larger particles that form from the quarks. The strong force differs from others ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

Lattice gauge theory, or lattice QCD, is a calculation method that helps scientists make predictions about the behavior of quarks at low energies. Quarks are particles found inside every atomic ...

A large and unexpected excess of top quark pairs has the physics community excited, but the interpretation is still up for debate. In 1995, Alexander Grohsjean cut out a story from the local German ...

Trillions of times smaller than a grain of sand and smaller than an atomic proton or neutron, quarks are among the smallest particles in the universe. They are essentially building blocks for ...

Based on the lectures and discussions of historians and physicists at the Second International Symposium on the History of Particle Physics, held at Fermilab on May 1-4, 1985.
