Intended for nonscience students, this undergraduate textbook defines the language of physics and explains the principles of motion, force, electromagnetism, energy, nuclear physics, light, relativity, quantum mechanics, and particle physics. Sadoff, (Cornell University) focuses on the methodology used to make scientific discoveries and how the field has changed over the last 100 years. Recommended for curious thinkers, although the addition of more graphics and practical examples would make future editions more engaging. Annotation ©2009 Book News, Inc., Portland, OR (booknews.com)
