Super Gear: Nanotechnology and Sports Team Up

Nanotechnology is the science of things at the nanoscale. It deals with microscopic particles called nanoparticles. Nano- means "one-billionth," so a nanometer is one-billionth of a meter.
Bigger is not always better. With nanotechnology, the little guy is the winner. Two key quotes from page four of the fascinating book Super Gear explain why. Smaller particles fit more tightly together than large particles, increasing the strength of the material and Atoms within a smaller particle also attract one another with greater force, resulting in stronger atom-to-atom bonds. The tighter bonds make for a much more durable substance. The manipulation of these nanoparticles has created gear in the sports world that puts Pierre de Coubertin's quote, Swifter, higher, stronger, on its head. But you can't talk about the super suits in swimming before you understand the why. Author Jennifer Swanson gets this so she explains in the first chapter how all of it works. Scientists are able to move nanoparticles with the use of a laser beam from an optical nanotweezer. What are the results of this work? Swimsuits that produced such fast times in the pool that the technology had to be curbed. The nanotech suits cut down on the drag from the water. This also works in track and field, cutting down times by as much as two hundredths of a second. That's enough to separate winners and losers. Other sports equipment that has been enhanced by nanotechnology includes baseball bats, golf clubs, and tennis racquets. Think about the changes in what we wear to play our games. It's no longer enough to slap on a sport gray t-shirt. Your 5K time will be slower than the runner who has the cool sweat-resistant shirt. Before you talk about sports "back in my day" and chase kids off your lawn, it's not just the reduction of time or increase in distance that nanotechnology has affected. It's also making sports safer with better helmets and running tracks that cut down on injury.
Speaking of little spaces, it's almost impossible to include all of the cool details from Super Gear in this blog rectangle. It will change the way you look at your favorite sport. I'm watching Chiefs-Raiders right now and thinking about helmets and uniforms instead of my beloved fantasy team. Wonder why we have so many highlights of great catches by receivers? Is it the gloves, money? In children's literature, we have a lot of biographies of sports figures, but not very much in the way of sports science. This interesting mix of science and sports will hopefully lead to more texts like Super Gear in the near future.
