- organising data
- synthesising information
- making predictions ]]> 2018-10-22 08:26:29 UTC https://padlet.com/abiramibaskaran3/qf9lpw1qagpz/wish/295335351 Types of Models abiramibaskaran3 https://padlet.com/abiramibaskaran3/qf9lpw1qagpz/wish/295335751 1. Physical
2. Mathematical
3. Conceptual]]> 2018-10-22 08:27:50 UTC https://padlet.com/abiramibaskaran3/qf9lpw1qagpz/wish/295335751 Variables mbyao2 https://padlet.com/abiramibaskaran3/qf9lpw1qagpz/wish/295336003 more variables increases how close the model is to the real system 
However, more variables increases uncertainty

- Used to explain a phenomena that cannot be experienced directly
- A simplification of the natural world

- visualize complex systems
-provide analogies
-serve as heuristic devices
-used as arguments for plausibility of causal agents]]> 2018-10-22 08:36:05 UTC https://padlet.com/abiramibaskaran3/qf9lpw1qagpz/wish/295338566 mbyao2 https://padlet.com/abiramibaskaran3/qf9lpw1qagpz/wish/295339980 may have to omit certain parts of the real system in order to understand it 
Thefore will be "wrong" to some extent]]> 2018-10-22 08:41:01 UTC https://padlet.com/abiramibaskaran3/qf9lpw1qagpz/wish/295339980 computing power mbyao2 https://padlet.com/abiramibaskaran3/qf9lpw1qagpz/wish/295340341 model complexity and (number of variables) and level of detail limited by computer power]]> 2018-10-22 08:42:16 UTC https://padlet.com/abiramibaskaran3/qf9lpw1qagpz/wish/295340341 Failures of equipment and failures to understand the limitations of our equipment https://padlet.com/abiramibaskaran3/qf9lpw1qagpz/wish/295340616 2018-10-22 08:43:11 UTC https://padlet.com/abiramibaskaran3/qf9lpw1qagpz/wish/295340616 Models are open https://padlet.com/abiramibaskaran3/qf9lpw1qagpz/wish/295341467 1.Conceptualization (how we frame the problem)

2.Empirical adequacy ( how well our mathemathical representations map onto natural processes.

3. Input parameterization (how well numerical varianles represent elements of the system)

therefore there's always uncertainty in how accurate models are e.g. ozone not included until ozone hole discovered]]> 2018-10-22 08:48:24 UTC https://padlet.com/abiramibaskaran3/qf9lpw1qagpz/wish/295342120 Mathematical model abiramibaskaran3 https://padlet.com/abiramibaskaran3/qf9lpw1qagpz/wish/295343497 - uses mathematical language and concepts]]> 2018-10-22 08:53:59 UTC https://padlet.com/abiramibaskaran3/qf9lpw1qagpz/wish/295343497 A good/successful model https://padlet.com/abiramibaskaran3/qf9lpw1qagpz/wish/295344127 1. Relatively small numbers of parameters

2. Highly repetitive

3. Enormous database
