A truly complete biography of the great man. Some adequate discussion of his theoretical and scientific work, but the accent here is on his personal life. Many anecdotes, many quotes from him, many references and hotlinks to other...

In addition to overviewing Compton's (1892-1962 CE) studies in x-rays, this article includes information on Compton's published works, his education, and personal life.

In this lesson students learn how AM radios work through basic concepts about waves and magnetic fields. Waves are first introduced by establishing the difference between transverse and longitudinal waves, as well as identifying the...

An explanation of how X-ray machines work. An online activity in which a comparison is made between how the hand would be viewed with X-ray versus with visible light. An additional page explains the use of X-rays in CAT scan devices.

A complete, multi-page tutorial on infrared radiation and its importance to astronomical studies.

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...

Article explains the experiments on the photoelectric effect and how these experiments led to the idea of light behaving as a particle of energy called a photon.

NOAA has produced a series of topic papers for use by teachers and students. This paper is on the increase of radio wave activity and the effects solar emissions have on it. PDF format.

Using new technology related to examining artwork, The Art Institute of Chicago was able to uncover unknown details about one of Picasso's most famous works, "The Old Guitarist." Fascinating discoveries and technological processes make...

Provides a long list of physics formulas for easy reference.

Resource provides a biography of the scientist Andre Marie Ampere.

Build your own windmill and see how the wind can be converted into energy to produce electricity. This science fair project should help you understand the use of wind as a source of alternative energy. The Science Buddies project ideas...

In the following interactive students will begin to understand the four basic forces that underlie the processes in nature.

Visit this site for an interactive tour of the atom and all aspects of particle physics. View the animations available with almost every description on this site. A great place for the fundamentals of particles and forces including a...

[Free Registration/Login may be required to access all resource tools.] In this online lesson students will investigate examples of kinetic and potential energy and their transformations.

Light is all around you, with wavelengths bigger than mountains and smaller than atoms. Learn about light waves, and the ways in which light interacts with matter, with this lesson plan.

Take a look at light with these three easy experiments

This site explores the history of power lines and cancer associations, as well as dispelling the myth. The science is explored by citing known facts, studies and experts in the field.

Simulate the motion of a charged particle in electric and magnetic fields, and then complete the equations of motion using the Lorentz force law.

The MagLab's bus tunnel has an aluminum track, but it doesn't carry passengers: it carries electricity, up to 56 megawatts of it.

The railroad industry began in the frontier days, magnetic levitation has moved it squarely into the space age.

Can you hear a magnet? In this activity you will be able to transfer the sound from your iPhone, iPod or radio to a cassette-tape player.

This site, in German, offers numerous apps that illustrate common physics principles. Apps are organized into categories: mechanics, oscillations and waves, electrodynamics, optics, thermodynamics, the theory of relativity, physics of...
