Dartmouth College, Hanover, New Hampshire, Spring of 1977. In this lecture, Donella Meadows has a lively discussion with her students at Dartmouth College as they create a model to express the relationship between epidemic diseases and mosquitoes. Donella engages with her students and reminds them that they can make models however they want. Models never express the full complexity of real systems; they will always have some simplification.
