Role of models is often overstated.

Scientific progress can happen from simple observations.

perfect computation simply reproduces Nature, does not explain her

Anderson, Nobel Laureate, 1977

•lead to unexpected outcome, verifiable

•created or used in hindsight to explain diverse observations

•existing models adapted or grouped in novel manner to design

•used to express data, reveal patterns or implemented in control algorithms
