A learning module with built-in interactive features where students can explore the fascinating topic of matter tunneling through a barrier. They will learn how electron waves can sometimes manage this, devices that use this concept, and...

Introduction to the quantum mechanical model of the atom: Thinking about electrons as probabilistic matter waves using the de Broglie wavelength, the Schrodinger equation, and the Heisenberg uncertainty principle. Electron spin and the...

Provides a long list of physics formulas for easy reference.

Why do physicists want to study things at temperatures so cold atomic motion almost comes to a halt? And how do they create such frigid environments, anyway? Read on for the what, how and why of low temperature physics.

The Pauli Exclusion Principle shows how electrons fill atomic orbitals. Includes biographical information on Wolfgang Pauli.

This site from the University of Colorado at Boulder has great information on the Pauli Exclusion Principle. Pictures are provided along with links to additional information. The information provided is not in-depth and it is...

A lovely biographical piece about Ernest Rutherford. A number of personal notes, along with extensive information about the physics work he did. Nice quote at the end.

What does color have to do with particle physics? This page explains the concepts of color and the color force, which are fundamental subjects in quantum chromodynamics.

A collection of video lectures from course investigating the theory behind modern physics taught at Stanford University. The course introduces the basic concepts of particle physics by teaching about light, quantum field, Diary Equation,...

The life and many accomplishments of Albert Einstein are detailed in this article. Includes descriptions of his scientific theories and contributions.
