This textbook provides a unified approach to acoustics and vibration suitable for use in advanced undergraduate and first-year graduate courses on vibration and fluids. The book includes thorough treatment of vibration of harmonic oscillators, coupled oscillators, isotropic elasticity, and waves in solids including the use of resonance techniques for determination of elastic moduli. Drawing on 35 years of experience teaching introductory graduate acoustics at the Naval Postgraduate School and Penn State, the author presents a hydrodynamic approach to the acoustics of sound in fluids that provides a uniform methodology for analysis of lumped-element systems and wave propagation that can incorporate attenuation mechanisms and complex media. This view provides a consistent and reliable approach that can be extended with confidence to more complex fluids and future applications. Understanding Acoustics opens with a mathematical introduction that includes graphing and statistical uncertainty, followed by five chapters on vibration and elastic waves that provide important results and highlight modern applications while introducing analytical techniques that are revisited in the study of waves in fluids covered in Part II. A unified approach to waves in fluids (i.e., liquids and gases) is based on a mastery of the hydrodynamic equations. Part III demonstrates extensions of this view to nonlinear acoustics. Engaging and practical, this book is a must-read for graduate students in acoustics and vibration as well as active researchers interested in a novel approach to the material.

The Cristallerie de Clichy was arguably the finest paperweight maker in the world during the classic period. In their relatively short history they made some of the finest weights ever produced. This book is the history of Clichy, focusing on its magnificent glass paperweights. The author has spent over thirty years, and driven over a million miles, researching and photographing weights for inclusion in this book. Here the reader will find the history of the crystalworks and its wonderful creations. Also included is an overview of the period world's fairs, starting with the first one, the London Crystal Palace Exhibition in 1851. Clichy was an award winner and major contributor to these stunning exhibitions which helped shape industry and commerce worldwide.Clichy's classic period millefiori and lampwork paperweights, as well as cameo and foil incrustations, and paperweight-related objects are covered in detail. The broad range of approaches to a subject and the relative rarity of each is discussed. Clichy's weights-from the most common to the rarest-are all here. This book is a must for any connoisseur of Clichy crystal or paperweight collector. This large format book has 240 pages and is lavishly illustrated with almost 900 color photographs and over 100 original drawings..... As we have come to expect from Paul Dunlop, the illustrations are outstanding; he has captured the typical warm, rich colors of Clichy paperweights beautifully and goes to great pains to show the weights their actual size.This long-promised volume, Clichy Paperweights-classics of the nineteenth century, brings an impressive amount of new information to light. Everything you wanted to know or cared to imagine about Clichy paperweights can likely be found in this truly outstanding reference book which should rightly take a prominent place in every serious collector's bookcase.John D.
