One child approaches me asking to decode the infinite. He asks of the convergence and divergence and of the beauty and intricacy in series, sequences, integrals, and more. I share what I know, for I alone am too small. The businessman seeks guidance in optimization. He asks of the stochastic processes, minimizing costs, and of the evolving global tax policy in the context of their endeavor. I cannot design the nanotechnology or the social network or the cure they offer. I can share what I know, although I alone am too small. I can fill the gaps. in knowledge, in experience, in space— where others lack, where they cannot move the expanses of heaven and earth alone, I can stand. I share what I can, teach what I know, to help others change the world. I am but one small piece of a nearly infinite series, but together we can be infinitely grand.
