We live in an age of unprecedented power. Mighty engines power race cars hundreds of miles per hour, pull freight trains that are literally miles in length, lift mammoth airplanes off the ground carrying hundreds of passengers with all their cargo, and hurtle tons of sophisticated scientific equipment into space. By harnessing the power of the atom we have created enough energy to light entire cities and enough weaponry to annihilate them many times over. Power is something we are just beginning to understand. We know what power is.
Athletes are power conscious.
Baseball has its power hitters, football its power runners, basketball its power forwards. Weight lifters may be billed as the most powerful men in the world. Athletes in nearly every sport are striving for greater power to establish new world records. Power is something with which we are all familiar. We can grasp its significance.
