Based on lectures by the author, this volume is designed as a textbook on general ultrasonics. The text provides coverage of the propagation of ultrasonic waves in media with different elastic properties and under conditions close to those encountered in scientific and practical applications of ultrasound. As well as classical material and data from original sources, the book includes experimental data on the velocity of sound in isotropic solids and crystals. Each chapter is complemented by problems and their solutions.
What did you learn today and who from? This is not just a feel good book; it is a thought book as it will get you thinking. This book is dedicated to my mum, our friend Tim Dasilva and little Tal Doron who were taken from us way too soon. I never tried to write a book before as I'm not a writer. I'm just a guy that's been cutting hair for the past 23 years in England and Canada. I'm not a person who is always positive and think that everything is going to be great, as life does happen. I just wrote the book because someone told me I couldn't and wouldn't. I found out that the stories you have can help people at times. As the stories that they have might help you. Give yourself a bit of time to hear what people are saying. After reading this book you will not be a champion hairdresser as it has nothing to do with hair really. If you keep this book around and when things happen in life you might find something to help you get through it. As these are my real stories and real advice. Hear is what I have to say so far.
