Enrico Fermi was a titan of twentieth-century physics. He outlined the statistical laws that govern the behavior of particles that abide by the Pauli exclusion principle and developed a theoretical model of the atom in his mid-twenties....

The beginning of an informative tutorial on antimatter, covering quarks, hadrons, baryons, mesons, leptons, and neutrinos.

This site from Wikipedia provides a wonderful in-depth explanation of ferromagnetism, covering the atomic behavior which is responsible for ferromagnetic properties. Also introduces the concepts of magnetic domains and the Curie...

Learn about atomic structure and the multiple theories of atomic structure in this simulation.

Have you ever wondered who discovered the electron? The answer is Nobel Prize winning physicist Sir Joseph John Thomson.

A very lengthy page from friesian.com discussing Bohr's theory of electronic energy levels and the explanation of commonly observed atomic emission line spectra. The concept of a photon and Einstein's observation of the photoelectric...

An introduction to the Standard Model, a theory which attempts to explain atomic structure using leptons, quarks, and force carrier particles.

The nature of insulators is described at the atomic level. Band gap theory is used to explain what distinguishes insulators from conductors.
