This program covers the important topic of the kinetic theory of gases in Physics. We begin by discussing the theory, which involves how energy is transferred to a gas and what results from the motion of gas molecules. The entire lesson is taught by working example problems beginning with the easier ones and gradually progressing to the harder problems. Emphasis is placed on giving students confidence in their skills by gradual repetition so that...

For all of their ubiquity, personal computers, email, and the Internet represent a major departure in the evolution of computer technology. Witness the exciting and improbable birth of personal computing in the 1970s, and explore the nature of the virtual world where more and more people now reside..

This program covers the important topic of conservation of energy (part 2) in simple harmonic motion in Physics. We begin by discussing how in a perfect system energy is neither created nor destroyed. As the object swings, the energy is continually transferred from kinetic to potential forms and vice versa. The entire lesson is taught by working example problems beginning with the easier ones and gradually progressing to the harder problems. Emphasis...

From the American dust bowl of the 1930s to the relentless expansion of the Sahara in Africa, drought represents severe weather that can stretch out for years. Explore what’s going on in the atmosphere to create extreme drought, which is associated with heat waves and dust storms.
