Casti Five More Golden Rules by John L. Casti

A collection that presents five elegant mathematical principles in clear, nontechnical prose, blending intuitive explanations, historical anecdotes, and surprising applications. Each chapter unpacks a single “rule,” demonstrating how abstract mathematical ideas illuminate real-world phenomena—from probability puzzles and optimization to patterns in social and economic systems—while offering thought experiments and accessible proofs to engage general readers and showcase the conceptual beauty of mathematics.
