Introduction
Physics is the study of nature in its simplest form. Limited abilities and limited time force all scientists to narrow the scope of their understanding of nature in some way. Thus a biologist may concentrate primarily on whole organisms, or on cells, or on molecular genetics. A geologist may study crustal movements, or concentrate on crystal formation in a particular rock type. Underlying both biology and geology is chemistry which helps to clarify how and why molecular structures change. Even more basic than chemistry, however, is physics. The physicist studies conditions of far less complexity than does the biologist, geologist, or chemist. In doing this, he/she can investigate the most fundamental forces in nature, which, presumably, are at the root of all the complex sciences.
By working at the very edge of human understanding, the physicist is not primarily explaining why something happens, but is describing what happens in as clear and comprehensive a way as possible. This is why some knowledge of physics is so essential to anyone who plans advanced study in one of the sciences or in engineering.
As it is our deepest and best understanding of nature, physics should be part of the studies of any well educated person. It has become fashionable in recent decades to think of the sciences and humanities as separate, compartmentalized disciplines with little to offer each other.
The study of physics reveals a unity and deep beauty in the universe that is not obvious to the casual observer. The physics you will learn is thought to be true for all space and all time, and perhaps the only subject you'll learn that is studied throughout the galaxy and universe. As you travel throughout the site, you will begin to glimpse a new and profound reality.
This web site is based upon Patrick H. Canan's book a beginner's guide to Classical Physics (© 1982). Mr. Canan's text has been used within his physics classes for several years. The complete text contains 23 chapters, covering kinematics, statics, dynamics, energy, gravity, fluid statics, thermodynamics, electricity, and magnetism. Every chapter of the text has been converted to a form that your web browser can read. We have added several unique elements that supplement the text in teaching students physics. Please check back often for the latest updates.
