"The term isomorphism applies when two complex
structures can be mapped onto each other, in such a way that to each
part of one structure there is a corresponding part in the other
structure, where “corresponding” means that the two parts play similar
roles in their respective structures."
Douglas R. Hofstadter, Gödel, Escher, Bach: An Eternal Golden Braid
Starting from this commonly applied definition, this poster series seeks to illuminate the term isomorphism in a variety of contexts. The term holds more specific and distinct meanings in Gestalt psychology and evolutionary biology, among other fields. Each poster explores a pair of related structures.
