Summary

For one-semester course in Physics for non-majors. Designed to help students achieve the science literacy that is essential for full participation as a citizen of our times, this text explores the grand principles of modern physics and their philosophical and societal connection to our culture and our individual lives. Non-technical and culturally sophisticated, it is a true alternative to standard technical texts and de-mathematized versions of the standard texts.
