the story of a centipede who was walking along and met a toad, who remarked to the centipede, "Isn't it wonderful? You have one hundred feet and yet you know when to use each one," at which point, "the centipede began to think about which foot to use next and was unable to move." "It is a profoundly erroneous truism," said the great mathematician Alfred North Whitehead, "that we should cultivate the habit of thinking of what we are doing. The precise opposite is the case. Civilization advances by extending the number of important operations which we can perform without thinking about them." The math education of my father's day produced a whole generation of great scientists and engineers. They are the ones who sent men to the moon and who


pioneered the computer revolution. They followed the great German scientists of the nineteenth century whose classical education enabled them to conduct the relativity and quantum revolutions in physics, and the development of genetics in biology. I asked my father one time whether he took calculus in high school. I was curious because so many of today's schools push advanced mathematical subjects younger and younger in the curriculum. "I never even heard of calculus until after I graduated from high school," he said. Poor man. If only he'd had some of the advantages of today's students, maybe he could have achieved something in life.
