The sole purpose of this blog is to articulate what I have learned over the past 40 years about the mechanics, biomechanics and physics of skiing in the hope that it will help to encourage the application of sound principles of science for the betterment of this great sport. Although the following US Patents and associated international patents were granted to me all these patents have expired and are now in the public domain for all to use and enjoy. I have no association or affiliation of any kind with the ski industry. Nor am I involved in any capacity in the sport for other than for my personal enjoyment and to assist other skiers and racers as time permits.
