Meet the concept

↗

A mathematical model is an equation that expresses the essential features of a system or process in mathematical terms. The speaker explicitly broadens the definition beyond physical systems.

Conditions: The model captures essential features rather than every detail.; The modeled object may be a physical system or a nonphysical process.

Meet the concept

↗

Mathematical modeling is the process of translating a real-world problem into a mathematical model by making specific assumptions and approximations while still capturing the essence of the original problem.

Conditions: Must start with a real-world problem; Must result in a mathematical model; Requires making assumptions and approximations

Find a method

↗

The workflow is: start from a real-world problem, use assumptions and approximations during mathematical modeling to obtain a mathematical model, solve that model, and then apply the solution back to the real-world situation.

Conditions: The initial step translates a real-world problem into mathematics.; The final step interprets the mathematical solution in the original real-world context.
