B.1.3 Limitations of Mathematical Models Notes
What are Mathematical Models
Mathematical models are also known as computer models, which use equations and algorithms to predict outcomes or simulatebehaviors in fields like physics, biology, economics, and engineering.
These models are essential for understanding systems that are too complex or dangerous to study directly.
However, mathematical models have inherent limitations that can affect their accuracy and reliability.
Example
Weather forecasting relies on mathematical models that simulate atmospheric conditions.
While these models are highly advanced, they still struggle to predict weather accurately beyond a few days due to the chaotic nature of the atmosphere.
Key Limitations of Mathematical (Computer) Models
1. Simplification and Assumptions
Mathematical models often rely on simplifications to make complex systems manageable.
These assumptions can introduce errors if they do not accurately reflect real-world conditions.
Example
A model predicting the spread of a disease might assume a uniform population density, ignoring variations in urban and rural areas.
This simplification can lead to inaccurate predictions.
2. Incomplete Data
Models are only as good as the data they use.

Introduction to Mathematical Models
Mathematical models are representations of real-world systems using mathematical concepts and language.
They are used to predict outcomes or simulate behaviors in various fields like physics, biology, economics, and engineering.
These models are essential for understanding systems that are too complex or dangerous to study directly.
ExampleWeather forecasting relies on mathematical models that simulate atmospheric conditions. While these models are highly advanced, they still struggle to predict weather accurately beyond a few days due to the chaotic nature of the atmosphere.
DefinitionMathematical ModelA mathematical representation of a real-world system using equations and algorithms to predict or simulate behavior.
AnalogyThink of a mathematical model like a flight simulator for pilots. Just as the simulator mimics real flight conditions to train pilots safely, mathematical models mimic real-world systems to help us understand and predict their behavior.
