Book excerpt: Currently, economics and cognitive science are heavily rooted in Newtonian physics, successfully borrowing a great deal of modeling tools from it. This is a great achievement. You do not need quantum mechanics or theories of relativity to build a house or bridge. Nevertheless, no one would deny the importance of modern theoretical physics. I believe many intellectuals have realized the need to go beyond the limitations of the Newtonian tradition for means of social science research. The big question is how to do it and how to do it right. This book aims to integrate economics and cognitive science by applying theoretical physics from a modeling perspective. During the course of this book, necessary background knowledge preparations for understanding the content topics are also briefl y provided. Thus, this book is designed to be conceptually and instrumentally self-contained. Everyone interested should be able to read it.
