This book offers a self-contained tour of applied category theory, aimed at readers with minimal background. It introduces advanced category-theoretic ideas through concrete, real-world examples such as electrical circuits, control theory, and databases, giving a taste of each topic rather than a comprehensive treatment.

Key Topics

• Orders and adjunctions
• Monoidal preorders
• Database schemas and functors
• Profunctors and co-design
• Hypergraph categories and operads
