From the introduction: An equation can't predict your future . . . But it can help you plan for itMost books about retirement planning are written as guides, instruction manuals or "how-to" books. The authors tell you what to do, when to do it, and what to expect. I know this quite well because I have authored many such tomes myself. Rest assured, this is not one of those books.This book tells stories which I hope will lead into conversations. It is a narrative involving seven people, their discoveries and the conceptual innovations that made it possible for you to stop working and enjoy the money you have accumulated, one day. These protagonistsor scientific heroesdidn't achieve their breakthroughs while hunched over a laboratory workbench, peering through a microscope or trekking through jungles. They made their discoveries sitting in front of a blank sheet of paper, but while thinking very carefully about life and money. And, like the greatest thinker of them all, Albert Einstein, they too expressed their discoveries using a very beautiful language called mathematics. Alas, the seven equations profiled in this book aren't as famous or as elegant as the simplicity of E = MC 2, but they are far more practical for your retirement.Yes, I know from many years of teaching experience that financial conversations are often dry and humorless. So I promise to do my best to lighten up the topic by keeping the technicalities to a minimum and focusing on the art. "Art," you say?Yes. In my mind, famous equations are like beautiful Picassos. Even if I don't quite understand the painting or the mathematics I can certainly appreciate the beauty and genius behind it. The seven equations presented in this book typify, at least for me, the conciseness, elegance and beauty that the best of the best equations demonstrate. By the end of this book, if you're not already inclined to appreciate mathematical equations for what they are, I hope you'll agree about the beauty.
