I now want to tell three stories about advances in twentieth-century physics. A curious fact emerges in these tales: time and again physicists have been guided by their sense of beauty not only in developing new theories but even in judging the validity of physical theories once they are developed. Simplicity is part of what I mean by beauty, but it is a simplicity of ideas, not simplicity of a mechanical sort that can be measured by counting equations or symbols.
Maybe, through the stories I share about my life and others and the medical research that has been dedicated to the world of positive psychology, they'll relate to the power of a positive perspective and change the world one person at a time. Pipe dream, of course, but I love the thought of being given the chance to inspire!
