Originally published in 1934, this book identifies and analyses the different types of waves most prevalent amongst the world's oceans and rivers and is an account of the author's original contributions to the knowledge of wave phenomena. Chapter one comprehensively explores the size and speed of ocean waves in relation to the velocity of wind, chapter two analyses waves in sand and snow formed and propelled by wind and current, whist chapter three investigates tidal bores and other progressive waves in rivers. The book also contains a variety of insightful and fascinating photographs presenting the different varieties of wave formation, such as tidal sand waves, leaping waves and the roll waves of a stream. This book will serve as an important reference work for researchers in the field and will be of considerable value to anyone interested in geophysics, climatology and oceanography.

Sailing across time and geography, the imaginary and the real, The Sea chronicles the many physical and cultural meanings of the watery abyss. This book explores the sea and its meanings from ancient myths to contemporary geopolitics, from Atlantis to the Mediterranean migrant crisis. Richard Hamblyn traces a cultural and geographical journey from estuary to abyss, beginning with the topographies of the shoreline and ending with the likely futures of our maritime environments. Along the way he considers the sea as a site of work and endurance; of story and song; of language, leisure, and longing. By meditating on the sea as both a physical and a cultural presence, the book shines new light on the sea and its indelible place in the human imagination.

The revised and enlarged third edition of this successful book presents a comprehensive and systematic treatment of linear and nonlinear partial differential equations and their varied and updated applications. In an effort to make the book more useful for a diverse readership, updated modern examples of applications are chosen from areas of fluid dynamics, gas dynamics, plasma physics, nonlinear dynamics, quantum mechanics, nonlinear optics, acoustics, and wave propagation. Nonlinear Partial Differential Equations for Scientists and Engineers, Third Edition, improves on an already highly complete and accessible resource for graduate students and professionals in mathematics, physics, science, and engineering. It may be used to great effect as a course textbook, research reference, or self-study guide.
