Physical Science: How Things Work

Catalog description

Do you know how electricity is generated? How do instruments create music? What makes refrigerator magnets stick? For that matter, why is ice skating possible, how do wheels use friction and why can someone quickly remove a tablecloth without moving any dishes? All of the devices that define contemporary living are applications of basic scientific discoveries. The principles underlying these devices are fascinating as well as useful, and help to explain many of the features of the world around us. This course familiarizes you with some basic principles of physics by examining selected devices such as CD and DVD players, microwave ovens, the basic electronic components of computers, lasers and LEDs, magnetic resonance imaging as used in medicine, and even nuclear weapons. In learning the basic physics behind these modern inventions, you will develop a deeper understanding of how the physical world works and gain a new appreciation of everyday phenomena that are ordinarily taken for granted. The course is designed for non-science students with an interest in the natural world.
