Acknowledgments

Discussions with colleagues led us to write about the strong interaction between science and technology, economics, and legislation in our modern society. We thank the hundreds of students who have been patient with our presentations and taught us that the KISS (Keep It Simple Stupid) theory of teaching really works. Complex solutions are best formulated by answering a series of well-stated simple questions that leave a trail to that complex problem solution.

Thanks are due for the hospitality of the Chemical Engineering Department shown by a Professor in retirement (TSS). This was an inspiration that made partnering in this writing project possible.
