Physics is frequently one of the hardest subjects for students to tackle because it is a combination of two of the toughest subjects for most students: Math and Word Problems. What sets this series apart from other physics teaching tools is that the concepts are taught entirely through step-by step example problems of increasing difficulty. It works by introducing each new concept in an easy to understand way and using example problems that are worked...

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.

Today’s networked culture is a dream come true for researchers in fields from marketing to sociology to epidemiology. Learn how big data puts potentially everyone and everything under the microscope of analysis, creating a comprehensive view of the intricate reality in which we are all mere atoms..

This program covers the important topic of standing waves and resonance (part 2) in Physics. We begin by discussing how waves can be made to reflect off of an object and interfere in the opposite direction to the original wave leading to a standing wave. 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...

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 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...

Continue your investigation of social reality by looking at the concept of progress. Social optimists and pessimists alike believe that society is progressing, but they see different causes. Evaluate their theories, and explore the idea that Western culture is doomed to collapse under its own weight..

Discover the origin of Earth’s great variability in air temperature, and learn how it also explains the seasons. Search for the highest and lowest temperatures on the planet, and the locations with the greatest difference between highs and lows. Along the way, encounter the deadliest weather on Earth.

This program covers the important topic of heat engines and the second law of thermodynamics in Physics. We begin by discussing the theory, which involves how useful work can be done by engines which use expansion or hot gases to move a piston. 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...

This program covers the important topic of sound intensity and sound level in Physics. We begin by discussing how sound waves carry energy and how it is sometimes convenient to discuss the energy carried by a wave in terms of its sound intensity or sound level. 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...
