This experience provided both a broad understanding of scientific principles and practical experience applying scientific approaches to address major issues facing humanity. It was an ideal background for the author to teach a course "Science and the Big Issues of Our Time" at the University of the Third Age (U3A) in Brisbane, Australia. This book conveys the content of that course. Students in the course represent a diverse group of seniors. Most have little science education but, as a group, they bring to class about 2,000 years of life experience and wisdom. They have lived through an extraordinary period in human history, and witnessed some of the most exciting and challenging events that brought society to where it is today (for better or worse). Many have limited knowledge of mathematics, but they expect thorough and rigorous explanations that they can un
