ACROSTIC, Puzzle by Emily Cox and Henry Rathvon
Edited by Will Shortz
This Sunday’s winning acrostic draws a humorous albeit a rather fragmented quotation from Gliding for Gold: The Physics of Winter Sports by Mark Denny.
After discussing the physical properties of ice and snow and describing the physics behind sliding friction and aerodynamic drag, Denny applies these concepts to such sports as bobsledding, snowboarding, and curling. He explains why clap skates would only hinder hockey players, how a curling rock curls, the forces that control luge speed, and how steering differs from skiing to snowboarding. With characteristic accuracy and a touch of wit, Denny provides fans, competitors, and coaches with handy, applicable insights into the games they love. The separate section of technical notes offers an original and mathematically rigorous exploration of the key aspects of winter sports physics. ~ amazon.com

The full paragraph of the quotation: Angular momentum is the tendency of a rotating body to keep rotating A spinning body has a high angular momentum if it is hard to stoop it from spinning. High angular momentum may derive from spinning the body very fast or from spinning a very heavy body. We are all familiar with the concept of angular momentum conservation, in practice if not in theory. We know that a spinning skater can increase her angular speed the rate at which she turns by drawing in her arms and legs. You may reproduce this behavior in a modest way by spinning on your office pedestal chair. First, get spinning with your legs extended, and then draw you legs in toward the chair axis. This action will cause your office colleagues to stare and you to spin faster. Extend you legs again and you slow down. If your boss complains, just say that you are learning some physics.
