Writing this book was mostly a solitary effort channeling ideas that I have formed over several years. I am responsible for all the ideas, the text, and the figures in this book. But after having written (and drawn) most of it for fun, when I thought of publishing it, I discovered that finding a publisher as an unknown, first-time author can be even more challenging than writing. That process was successful largely because I found the perfect literary agent for this book, Andy Ross, who shared my excitement about it. As the only person other than me who read all the chapters in detail before submission, his feedback was extremely valuable. My sincere thanks also go to my editor, Jennifer McCartney, at Skyhorse Publishing, for appreciating the value of a rather unconventional book. Her help and advice has been invaluable in transforming the manuscript into a published book. I am grateful to Rosario Torres, Sudarshan Fernando, and Eric Laub for helpful comments on some of the chapters. I owe much to my parents for raising me in an environment where I was always free to choose my own path and own beliefs in life and for encouraging diverse interests from early on.
