Systems and models

Models and simulations have always been an essential part of the human experi­ ence: as we get up in the morning, we crank up our mental model of the little world around us, run a few simulations in our mind on how we are going to deal with the problems and people we will meet during the day, try out different ap­ proaches, evaluate the likely outcomes, and start the day with a plan. It will not protect us from failures and surprises, but it will have prepared us to deal more ef­ fectively with whatever tasks await us.
