This program covers the important topic of refrigerators in Physics. We begin by discussing how refrigerators are just “heat engines” operated in reverse because they require energy to pump heat away from an object. 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...

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...

"The Circle is the exhilarating new novel from Dave Eggers, best-selling author of A Hologram for the King, a finalist for the National Book Award. When Mae Holland is hired to work for the Circle, the world's most powerful internet company, she feels she's been given the opportunity of a lifetime. The Circle, run out of a sprawling California campus, links users' personal emails, social media, banking, and purchasing with their universal operating...

Quantum mechanics gives us a picture of the world so radically counterintuitive that it has changed our perspective on reality itself. In Quantum Mechanics: The Physics of the Microscopic World, award-winning Professor Benjamin Schumacher gives you the logical tools to grasp the paradoxes and astonishing insights of this field.

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...

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...

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..

Survey the remarkable range of extreme weather around the planet. Then consider: Why does Earth have weather at all? Professor Snodgrass introduces basic features of the atmosphere that naturally lead to severe weather. He concludes by outlining the goals of the course—among them, preparedness.

In this and the next lecture, study the advanced technology that has revolutionized extreme weather forecasting. Here, look at how radar has vastly improved the prediction of tornadic thunderstorms. You’ve seen Doppler radar images in forecasts. Now learn how this all-important tracking tool works.

Reality for the individual ends at death. But medical technology is making that endpoint increasingly hard to define. Consider what it means to die and the complications that would ensue if we developed brain transplants or found the secret of immortality..
