A Tour of the Subatomic Zoo: A guide to particle physics is a brief and ambitious expedition into the remarkably simple ingredients of all the wonders of nature. With hardly a mathematical formula, Professor Cindy Schwarz clearly explains the language and much of the substance of elementary particle physics for the 99% of students who do not aspire to a career in physics. Views of matter from the atom to the quark are discussed in a form that an interested person with no physics background can easily understand.
