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
