Principles of space-time-matter: cosmology, particles and waves in five dimensions

Modern technological advancements have a significant role in the evolution of contemporary science. For instance, series of mysteries have been resolved and some are in queue. So far, the best invention in the history of humankind is computer as it has the ability in its current form to solve many complex problems for which a normal human brain can take centuries to solve. Many scientific problems that are difficult to solve through analytical methods, can be solved now through well-defined computational methods without difficulty. Therefore, it is essential to have good knowledge of computational techniques. In the book Computational Acoustics: Theory and Implementation, the author has efficiently introduced the basics of computational methods and software tools for their implementation. Moreover, the author has covered a series of problems from basics to advance, in the field of acoustics. In the introduction chapter, the author states: ‘The key feature of the presentation contained in this text is that it serves to bridge the gap between theory and implementation’. I agree that this book provides interesting and intellectually stimulating perspectives on computational acoustics. Author has covered the various computationalmethods such as the finite difference (FD) technique in the frequency domain, the finite difference time domain (FDTD) method, finite element method (FEM), and beam element method (BEM). The book invites the reader to think, how to design and analyse complex acoustic problems through computational methods. The book can be used as a textbook at advanced undergraduate level. In addition, the book can also be considered as a reference by both instructors and scientific research students for numerically solving the research problems. Apparently, author has covered the problems of acoustics however; the book can be used by researchers who are working on the problems of waves that involve similar analytical differential equations, e.g. electromagnetics, thermodynamics etc. Furthermore, as a positive suggestion, I would suggest the author to include more examples and their solutions with graphical illustrations, which would help to train the students and researchers in short time. The author has offered a unique collection of reference at the end of each chapter, which helps the reader to understand the concepts with more details. Computational Acoustics: Theory and Implementation, is a stimulating read that will train the readers in the field of computational acoustics and fluid dynamics. Overall, the current edition of the book is well-illustrated, and worthful to be considered as a reference book for early career researchers and tutors who are keen to expand their expertise in the field of computational methods for solving complex engineering problems.
