By the end of this section, you will be able to describe the definition, aims, and branches of physics; describe and distinguish classical physics from modern physics and describe the importance of relativity, quantum mechanics, and...

Discusses the connection between electricity and magnetism and the early work of Michael Faraday and James Clerk Maxwell. Electromagnetic interactions were first described by Maxwell. Continues on with a discussion of quantum physics and...

The FOM Institute for Atomic and Molecular Physics (AMOLF) is one of the five national research institutes of the Foundation for Fundamental Research on Matter (FOM). The research at AMOLF is focused on selected areas of atomic,...

A good explanation of basic quantum theory.

Austrian physicist Erwin Schrodinger, one of the founders of quantum mechanics, posed this famous question: If you put a cat in a sealed box with a device that has a 50% chance of killing the cat in the next hour, what will be the state...

One of the most amazing facts in physics is that everything in the universe, from light to electrons to atoms, behaves like both a particle and a wave at the same time. But how did physicists arrive at this mind-boggling conclusion? Chad...

Students learn about the Newtonian mechanics principle of conservation of angular momentum and the application in the quantum mechanical world.

You've probably heard that carbon dioxide is warming the Earth. But how exactly is it doing it? Lieven Scheire uses a rainbow, a light bulb and a bit of quantum physics to describe the science behind global warming. [5:01]

Theoretical physicist Richard Phillips Feynman greatly simplified the way in which the interactions of particles could be described through his introduction of the diagrams that now bear his name (Feynman diagrams) and was a co-recipient...

The dualistic nature of light is discussed. The photoelectric effect and the Davisson-Germer experiment are contrasted as empirical evidence supporting each of the two views - particle and wave - of the nature of light. The photoelectric...

A very technical explanation of the angular momentum of an electron.

[Free Registration/Login may be required to access all resource tools.] Students explore how the study of the hydrogen emission spectrum led to the Bohr model of the atom, in which electrons exist in states of constant energy.

This is a brief biography on the life and scientific work of Otto Stern, a physicist honored with the Nobel Prize in physics for his "development of the molecular ray method and his discovery of the magnetic moment of the proton."

Theoretical physicist Julian Schwinger used the mathematical process of renormalization to rid the quantum field theory developed by Paul Dirac of serious incongruities with experimental observations that had nearly prompted the...

Japanese theoretical physicist Sin-Itiro Tomonaga resolved key problems with the theory of quantum electrodynamics (QED) developed by Paul Dirac in the late 1920s through the use of a mathematical technique he referred to as...

Learn about the life and work of quantum physicist, David Bohm, who was a leading expert in the fields of theoretical physics, neuropsychology, and philosophy.

Learn about the scientist who pioneered developments in atomic and quantum physics, and also served as PhD supervisor for many Nobel Prize winners in physics and chemistry.

Learn about the life and work of one of the pioneers of quantum physics, Wolfgang Ernst Pauli.

A really nice (and short) dual article, on Parity and on Nonconservation of Parity. With diagrams and equations, but does not overwhelm.

Biography of Albert Einstein from an exhibit at Princeton University.

Explains the Heisenberg Uncertainty Principle, that it is impossible to know both the momentum and position of an electron, along with describing the impact that it made upon the scientific community upon its introduction in 1927.

The Nobel E Museum provides biographical information on Wolfgang Pauli, Austrian physicist and discoverer of the exclusion principle.

Contains a brief biography of nobel prize winner Carl E. Wieman.

A biography of Max Planck, covering his research interests and contributions to science, as well as more personal information about his family and life.
