Science Buddies profiles careers you perhaps never even considered. Do you know what a power distributor and dispatcher does? Someone has to control the flow of electricity along the transmission lines to be sure nothing takes the power...

Here is described a simple process to 'put a voice on a sunbeam' and transmit it over a distance. It is a fascinating example of amplitude modulation of light using sound vibrations. It then describes how the modulated light is detected...

Students learn about the properties of light as a photon and the wave-particle duality.

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."

This article from Khan Academy provides information about refraction and light bending. This information is intended for the Class 12 Physics Course (India).

Acting as a subtopic of the General Chemistry Virtual Textbook's section on Atoms and the Periodic Table, this site discusses the limits associated with classical physics. Topics covered include light and heat with additional information...

Lesson plan should be used for intermediate students. Students work in pairs or groups to create a shoe box that will bend light.

Discusses the validity of research showing that neutrinos travel faster than the speed of light.

This article helps explain the concept of electromagnetism as well as magnetic fields and the properties of the speed of light.

Learn about the diffraction of light using the wave model and Huygen's principle.

Physics students find out how to effectively define and clarify kinetic and potential energy.

An illustrated article helps physics students learn about center of mass and velocity, and define the concept of inertia.

Described is a simple low cost home-made device that converts the radio wave energy from a mobile phone signal into electricity to light an LED. No battery or complex circuitry is required. The device can form the basis of a range of...

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.

James Clerk Maxwell was one of the most influential scientists of the nineteenth century. His theoretical work on electromagnetism and light largely determined the direction that physics would take in the early twentieth century. Indeed,...

An interdisciplinary unit teaching the topic of scientific research performed on human subjects for a skin cancer study. The physics principles behind imaging techniques, the biological implications of UV radiation on the skin, the...
