This book is the product of many years of effort, and the list of intellectual debts that I have incurred in writing it is long. First of all, I am deeply grateful to Bruce Rogers, my coauthor on chapters 4 and 5.Without Bruce this book would not exist in its current form. Most of what I have learned about stochastic dynamical systems I learned from Bruce, who brought to the project a mathematician’s rigor and a deep curiosity about the workings of complex systems. If you find this book’s models of dynamic audience and the attention economy useful, Bruce deserves much of the credit.

这本书是多年努力的产物，我在写这本书的过程中所欠下的智力债务清单很长。首先，我非常感谢布鲁斯·罗杰斯，他是我第四章和第五章的合著者，没有布鲁斯，这本书就不会以现在的形式存在。关于随机动力系统，我学到的大部分东西都是从布鲁斯那里学到的，布鲁斯给这个项目带来了数学家的严谨和对复杂系统工作原理的强烈好奇心。如果你觉得这本书中关于动态受众和注意力经济的模型很有用，那么布鲁斯应该得到很大的赞扬。
