This article is a review of the theoretical concepts of the science of complexity (chaos and fuzzy logic theory) and systems theory present in the work of Julián Gil, presenting a concise explanation of the terms and key concepts. The objective is to understand the conceptual foundation and creative process of his work more deeply, and to show some of his works: the OCT and TONDOS series. Other theories related to the artist’s organizational and record-keeping methodology will also be discussed within the context of the science of complexity.
