==Why would you want to use a computational model?==
 +
*In short, to do something that is hard or impossible to do with a lab experiment.
 +
**If too many people are involved for it to be practical
 +
**If you want to [[simulation|simulate]] things that current technology doesn't allow us to measure
 +
**To validate with a more detailed model a hypothesized process derived from actual lab data
 +
**To propose a theory and test it for things that are not currently observable or practical.
