This short account of elementary particles written for the layman poses the questions: are quarks the fundamental building blocks of matter; what are they like; how many different kinds exist; and can they exist in the free state? What is the ultimate structure of matter? Is it made of atoms, small, simple, indivisible particles, or not? John Dalton's 'chemical atoms' turned out to be composite, composed of an electron cloud and a very small, very dense nucleus. This nucleus, in turn, was found to be composite, made up of protons and neutrons bound together by pions. All three of these (and many like particles) have now been found to be made of quarks. At first there were only three of these and they were thought to be long sought after fundamental building blocks. But now we know of at least 18 quarks, 18 anti-quarks and eight 'gluons' that hold the quarks together. The whole atomic idea is in doubt and the alternate possibility of a Universe that is one, whole and indivisible opens up. This fascinating book will be an inspiration to anyone wishing a first exposure to this intriguing and mystical area of modern physics.

No one has ever seen a quark. Yet physicists seem to know quite a lot about the properties and behavior of these ubiquitous elementary particles. Here a top researcher introduces us to a fascinating but invisible realm that is part of our everyday life. Timothy Smith tells us what we know about quarks--and how we know it. Though the quarks that make science headlines are typically laboratory creations generated under extreme conditions, most quarks occur naturally. They reside in the protons and neutrons that make up almost all of the universe's known matter, from human DNA to distant nebulae, from books and tables to neutron stars. Smith explains what these quarks are, how they act, and why physicists believe in them sight unseen. How do quarks arrange themselves? What other combinations can nature make? How do quarks hold nuclei together? What else is happening in their hidden worlds? It turns out that these questions can be answered using a few simple principles, such as the old standby: opposites attract. With these few principles, Smith shows how quarks dance around each other and explains what physicists mean when they refer to "up" and "down" quarks and talk about a quark's color, flavor, and spin. Smith also explains how we know what we know about these oddly aloof particles, which are eternally confined inside larger particles. He explains how quark experiments are mounted and how massive accelerators, targets, and detectors work together to collect the data that scientists use to infer what quarks are up to. A nonmathematical tour of the quark world, this book is written for students, educators, and all who enjoy scientific exploration--whether they seek a taste of subnuclear physics or just wonder about nature on the smallest of scales.
