What's the deal with 20th-century physics? How and why did it get so complicated, so abstract, that even Einstein had trouble believing in it? Most of us need someone to come along and explain it all in words that make sense; fortunately, astrophysicist and science writer extraordinaire John Gribbin has seized that role with a flair and passion unequalled. He has outdone himself with Q Is for Quantum: An Encyclopedia of Particle Physics, 545 pages of definitions, histories, and biographical sketches that illuminate the ever-expanding search for the most basic forces of nature in a style that is at once witty, clear, engaging, and scientifically rigorous. No serious student of modern science (no dilettante, either) should be without it when reading about the greatest intellectual work of our time.

Whether he's explaining the intricacies of quantum chromodynamics or exploring the wild life and ideas of Richard Feynman, Gribbin uses just the right words, illustrations, and even (gasp!) equations to perfectly express the essentials to his interested, intelligent readers. Of special interest are the extensive timelines that close the volume and anchor particular scientists and their achievements within the context of world history; these are both helpful in grasping the development of physics and excellent aids to browsing. So, whether you want to expand your knowledge of modern science or just need a little help on Monday's midterm, Q Is for Quantum is the right book for you. --Rob Lightner
