5. What is a model?  A model is a simplified representation of a phenomenon, process, actor, system, or any complex entity.

6. Examples of models – atom  Concept  Indivisible entities over which matter is built  Model  Dalton, 1807  solid sphere  Thomson, 1904  plum pudding  Rutherford, 1911  Positive nucleus + negative electrosphere  Bohr, 1913  Nucleus + electrons with different levels of energy  Schrondinger, Pauli  Subatomic particles Dalton, 1807Thomson, 1904Rutherford, 1911 Bohr, 1913

7. Examples of models – Shape of the Earth  Concept  Place where we live. Environment.  Model  Flat  archaic belief  Spherical  Pythagoras ( AD 570)  Suggested that Earth could be spherical  Aristotle ( AD 330)  First evidence: semi-circular shadow at moon  Eratosthenes ( AD 240)  First estimate of Earth’s circumference  Mathematics  Scotsman McLaurin (1742)  Flat  Carl Jacobi (1834)  Elipsoidal  Henri Poincaré (1885)  Periform  Dynamic  Modern geodesy FlatSphericEllipsoidPeriform Dynamic geoid

11. Why modeling?  Understand how the system behaves  Simulate future and alternative scenarios  Support decision making and public policies using scientific knowledge

12. Global Change Where are changes taking place? How much change is happening? Who is being impacted by the change? What is causing change? Human actions and global change photo: A. Reenberg photo: C. Nobre

13. Computational models If (... ? ) then... Connect expertise from different fields Make the different conceptions explicit

14. Why computational models?  Can represent heterogeneity  Formal language to represent the model  Avoid ambiguity  Stable description of the model  Implementation allows experiments  Reproducibility (How did you do that?)

15. Modeling is a cyclic process
