A Physical Model is usually a scaled down version of a real-life entity.
In our younger days, some schools and universities had Aero-modeling clubs. Ko Eddie (Edward Teoh, M64) helped run the Aero-modeling club.
A Mathematical Model is a representation of an idea, concept, theory using Mathematics. It could be a simple equation (e.g. F = ma), a system of equations (linear, non-linear, differential, partial differential, …) or much more.
A Computational Model leverages the power of computers. Many traditional subjects now have Computational aspect (or branch). Example : Computational Biology
- Probabilistic Model
- Stochastic Model
- Simulation Model (e.g. Discrete Event Simulation)
- Neural Networks
- Econometric Model
