Intended for the general reader, skiing enthusiast, and scientifically literate, this book covers the physics of skiing and the physical properties of natural and man-made materials (i.e. snow and skis) with much attention paid to the dynamics of movement. "The triple point" in this book has two meanings: one being the point where the three potential states of water (solid, liquid, and vapour) coexist and which obviously is of special concern to skiers. The second "triple point" occurs when the increased understanding of the "how" and "why" joins with the experience of "wow" and we feel the fullest enjoyment of the sport of skiing.
