Although it is arguably the most successful theory in physics, quantum physics has often baffled and confounded both its practitioners and the general public. This informative website discusses the types of mysteries, which still plague...

This Nobel Foundation site provides the "Presentation Speech by Professor S.A. Arrhenius, Chairman of the Nobel Committee for Physics of the Royal Swedish Academy of Sciences, on December 10, 1922."

The Nobel Foundation provides a fascinating speech by O.B. Klein of the Physics Committee. Elegant, erudite, and fully explanatory of the work of Lee and Yang. His description of a physicist on another planet is very insightful. This is...

The Committee on Elementary-Particle Physics, part of the U.S. National Research Council, presents this massive report on particle physics. It's a definitive document. Surprisingly readable, totally detailed. Start with the Table of...

An online textbook containing an introduction to quantum chromodynamics (QCD). This is a proposed theory about what causes quarks and gluons to form hadrons. Article contains a description of lattice QCD, an approximation to QCD that is...

An excellent overview of electron spin, what it means in non-mathematical terms and quantum mechanical terms.

Acting as a subtopic of the General Chemistry Virtual Textbook's section on Atoms and the Periodic Table, this site discusses the quantum revolution with special attention given to cathode rays and radioactivity.

This resource provides historic information on length measurement in the United Kingdom. Click on the topics on the left toolbar of the article to find out more information.

An overview of quantum mechanics which begins with why they are important and wraps up with an accident at Bell Telephone labs in 1925. Find several theories and formulas.

Discuss methods of working with probabilities and quantum physics in this article.

Albert Einstein publishes his special theory of relativity and his theory on the quantum nature of light, which he identified as both a particle and a wave. With ever new appliances, electricity begins to transform everyday life.

The Heisenberg Uncertainty Principle states that you can never simultaneously know the exact position and the exact speed of an object. Why not? Because everything in the universe behaves like both a particle and a wave at the same time....

A complete overview of Hund's rules including exceptions.

A mathematically understandable presentation of relativistic energy. Parts include Relativistic Energy, Rest Mass Energy, Conservation of Energy, Pair Production, Relativistic Kinetic Energy, and even Kinetic Energy. A couple of...

This article announces the discovery of the top quark and its significance in particle physics.

This page lists personal research interests, achievements, and publications of Carl E. Wieman.
