This revised and expanded bestseller includes a new chapter on putting, a new appendix on the fundamental physics covered in the book, increased coverage of modern club design, and an updated reference section. As in the previous book, most of the mathematics is relegated to a technical appendix. The first edition of this book was enthusiastically received by the both the science press in Physics Today, IEEE Spectrum, and Nature and the golf world in American Golf Pro and Golf Week.

The study of materials which exhibit new and unconventional properties is of central importance for the devel- opment of advanced and refined technologies in many fields of engineering science. In this connection there has been a rapidly growing interest in real fluid effects on wave phenomena in the past few years. A prominent example is provided by Bethe-Zel'dovich-Thompson (BZT) fluids which have the distinguishing feature that they exhibit negative nonlinearity over a finite range of temperature and pressures in the pure vapour phase. However, two phase flows with and without phase change...
