Review of the hardback: 'Researchers and advanced students of unsteady high-speed flow, particularly those concerned with the sound waves that are generated in such flows, will learn a lot by studying this book ... Michael Howe succeeds throughout the book in maintaining the lively style pioneered by his mentor to whom the book is dedicated, and in doing so will have made some readers understand this subject much better than they ever thought possible.' Journal of Fluid Mechanics Review of the hardback: 'Professor Howe is not only a well-established researcher but also an excellent pedagogue. He succeeded in explaining in a comprehensive manner complex topics of hydrodynamics and in making the reading a fascinating scientific journey. This book has all the chances to become a classical textbook on this subject. ... Howe's book should be recommended to all students willing to discover the wonderful world of hydrodynamics.'
