For many years I have been looking for a thorough book on vibrations and waves.  They are important throughout physics and electronics among other subjects.<br><br>This book is methodical in its introduction of the topics, the maths is well laid out and I have moved on leaps and bounds by referencing the sections of the book where I had blanks before.<br><br>I wish I had a copy many years ago and it will remain on my book shelf.
