James McNeil, professor emeritus of physics at Colorado School of Mines, was recently featured in an article about the physics of big air snowboarding in Scientific American. McNeil is the co-founder of the U.S. Terrain Park Council, a nonprofit dedicated to developing safer winter terrain park jumps using engineering design principles. From the article: Furthermore, the precise shape of the jump affects an athlete’s momentum; for example, a jump that curves sharply upward would induce backward rotation. A snowboarder could also get an extra unexpected angle at takeoff from changeable features ....
