Theoretical modeling is a research area that involves creating mathematical or computational models to study and understand complex systems or phenomena. These models are used to simulate and predict the behavior of the system under different conditions, allowing researchers to analyze and gain insights into the underlying principles governing the system. Theoretical modeling is commonly used in a wide range of scientific disciplines, including physics, chemistry, biology, and engineering, to explore complex phenomena that are difficult or impossible to study through traditional experimental methods alone. By developing and analyzing theoretical models, researchers can better understand, predict, and control the behavior of systems in various fields of study.
