It then lists some topics including an accidental informatician, a short story about good intentions going up in smoke, crocoite mineralogy, Schrodinger and his equation. It provides a definition of informatics as studying the structure, algorithms, behavior, and interactions of natural and artificial systems that process information and how digital processing has led to the study of informatics with computational, cognitive and social aspects.
