The Model

A model is a simplified representation of a real-world system or process that helps us understand, analyze, and predict how it behaves. It captures essential features and relationships, allowing us to study complex phenomena without seeing the entire complexity firsthand. Think of it as a detailed map or a blueprint—helping us make informed decisions by highlighting key factors and their interactions. Models are used across many fields, such as science, engineering, and economics, to clarify ideas, test hypotheses, and support planning and problem-solving.
