How to get paid for having fun

As I look back, I am still amazed that I was actually paid to do something I loved and others could describe as work. Yet my situation is no different from that of most scientists who find that they are asked to pursue their innate curiosity to solve puzzles, the solutions to which fortunately are of value to society. I enjoyed the beautiful logic of mathematics in elementary grades and was entranced by the exciting solution of puzzles described by DeKruif. So I drifted into the scientific profession without a clear idea of what to do or how to do it. Each experience prepared my mind and supplied the base for the next job, creating what was for me a smooth flow from scientist to professor to editor to scientist. Fortunately for me and fellow scientists the problems of the world never disappear. "The one who rides the tiger can never get off" is an aphorism that expresses society's dependence on science. Automobiles improve transportation and create pollution, medical advantages prolong life and create over-population, pesticides bring cheaper food and create soil problems. Each advance brings on the need for more science to solve the new problems. Society, which likes to live well, is addicted to the products of science, and fortunately a peculiar set of humans are addicted to solving the problems. I am one of those typical addicts who finds the obstacle course fascinating and the endlessness of the quest utopia.
