The spongy bones and tough-as-nails beaks of woodpeckers are inspiring a new generation of shock absorbers, potentially shielding airplane black boxes, football players and other valuable materials from the forces of impact.
The shots of hockey´s hardest shooters travel at slightly more than 100 mph.
On a relatively long-distance shot, 60 feet away from the goal, the goaltender will have 0.45 seconds to react.
Early hockey sticks were stiff and heavy (between 26 and 30 ounces) and made from a single piece of wood. Many modern sticks have shafts made from aluminum, graphite, fiberglass, titanium or Kevlar, to which wooden blades are glued (they weigh about 18 ounces). The sticks have varying degrees of flex, which adds to the power generated.
