This reissue of the classic 1932 edition of Lamb's Hydrodynamics is an indication of the lasting value of the work. Constantly in use since its first publication in 1892, this book is the definitive reference work for all fluid dynamicists. The new foreword by Professor R. Caflisch highlights the prominence of this treatise in the field and outlines the development of fluid mechanics that led to its publication. He also resolves possible conflicts with modern notation. Despite the rapid pace of research in modern fluid mechanics study and the advent of high-speed computers, Lamb's work remains a relevant, timeless classic.
