Super Gear: Nanotechnology and Sports Team Up

Gr 6–9—This title provides a fascinating insight into the developing world of nanotechnology applications in sports. The opening chapter outlines concepts of molecular bonding, including an illustration of the crystalline structure of ice. The text then segues into a lucid explanation of the very different forces at work in extremely small carbon nanoparticles. Subsequent chapters examine changes wrought by nanotechnology in particular sports: football helmets that absorb more energy and could protect against concussion, shoes and track surfaces meant to improve running speed and reduce injury, golf clubs and tennis racquets that are stronger and lighter, and swimsuits designed in conjunction with NASA intended to reduce drag. The sports connections are tied to standout athletes, including swimmers Alia Atkinson and Michael Phelps, golfers Michelle Wie and Phil Mickelson, speed skater Shani Davis, and tennis champion Serena Williams. Sidebars and simple drawings illustrate important concepts in physical science, especially lift, turbulence, and drag. One "Super Fact" sidebar shows how a single-walled carbon nanotube is narrower than a human hair in the same proportion as the hair is to a typical house. A hitch is that the science is so new that some of the technology is unproven. A sidebar on Jamaican sprinter Usain Bolt concludes that the effect of his nanotech shoes on his speed is unknown.
