The Physics of Skiing: Skiing at the Triple Point (Wirtschaftswissenschaftliche Beitrage, Bd 84)

"A fascinating look inside the complexities and enjoyment of skiing. For every skier, from the beginner to the Olympic Gold Medalist, this book provides a treasure of information." -PAUL MAJOR, ATHLETIC DIRECTOR, U.S. SKI TEAM "I was delighted to learn from this interesting book more about the physics of a sport I have enjoyed for more than seventy years." -NORMAN RAMSEY, NOBEL LAUREATE IN PHYSICS, HARVARD UNIVERSITY Just over ten years ago when the first drafts of this book were being written, and even more so a few years after that as it was making its way through the publication process, alpine skiing was experiencing what eventually became a complete revolution in equipment and tech­ nique: "shaped" or "parabolic" skis completely took over the market, and even relatively beginning skiers expected to carve graceful turns as they schussed down the slopes. Re-reading our work with an eye to revision, we have been surprised to see how our focus on the physics of skiing in the first edition al­ lowed us to recognize the fundamental importance of what were then quite novel changes in equipment and technique. The essence of the enhancement offered by shaped skis is their greater sidecut radius. Our original discussion (then and now in Chapters 3 and 4) of the crucial role that a ski's sidecut plays in carving a turn caused us to write, for the most part, as if the shaped ski had always been in existence. Sim­ ilarly, our interest in the geometry ofthe sidecut allowed us to discuss snowboards in some detail as well, for the key to their ability to "shred" down the mountain is their deep sidecut Understanding The Properties Of Snow And How It Changes And Interacts With The Skis Will Help You Appreciate The Special Phenomena That Occur At The Triple Point, Where The Solid, Liquid, And Vapor Phases Coexist. You'll Learn About Alpine, Cross-country, And Speed Skiing Techniques, Wax Performance, And You'll Get Scientific Data That Is Not Readily Available On The Technical Specifications And Performance Of Ski Equipment. The New Edition Will Include A Chapter On Biomechanics & Physiology Of Skiing. Other Chapters Will Be Revised & Brought Up To Date. The Discussion Of Alpine Skiing Will Include An Extensive Discussion Of The New Turning Skis.
