"On Growth and Form" is a landmark work that explores the science of biology from a mathematical perspective, emphasizing the patterns and geometry found in living organisms. The book discusses how physical and mathematical laws influence the way that organisms grow and develop, and how different species exhibit similar patterns of growth. It also touches on how these principles apply to the structure of the universe and the patterns found in nature. This work is considered a foundational text in the field of mathematical biology.

"Morphology of the Folktale" is a seminal work in the field of folklore studies that analyzes the structure of Russian folktales to identify their simplest irreducible narrative elements and their arrangement. The author introduces the concept of "functions" which are common plot devices used in folktales, and categorizes these functions into a consistent and repeatable framework. This structural approach to the study of tales reveals that despite the varied and complex surface of stories, their underlying structures follow a limited number of patterns. This methodology not only provides a tool for analyzing tales but also influences subsequent structuralist and narratological approaches in the broader field of cultural studies.
