Modeling and simulation allow us to peer into the future of complex systems. By mastering the balance between a model's simplicity and its accuracy, you can solve problems that are too large, too dangerous, or too expensive to test in reality.

"You cannot simulate without three things. First, the Real System—traffic, a heart, a factory. Second, the Conceptual Model—your math, your assumptions, your shortcuts. Third, the Computational Implementation—code. Most of you will fail because you forget that the computer is a liar. It does what you tell it, not what you mean."
