The Mathematics of Domino Tilings: From Puzzles to Physics

Have you ever wondered about the deeper mathematics hidden behind simple grid puzzles, like tiling a chessboard with dominoes? What starts as a childhood riddle actually lies at the intersection of modern combinatorics, probability theory, and mathematical physics. This text-only course guides you from basic tiling puzzles to the elegant mathematical frameworks used to analyze them. You will transition from solving simple grid problems to understanding how mathematicians model physical systems using discrete structures. What you will learn: - Understand the foundational concepts of grid graphs, bipartite matching, and domino tilings. - Apply combinatorial techniques like Kasteleyn theorem to count possible tilings. - Explore the connection between tiling configurations and statistical physics models. - Learn how probability theory describes the random behavior of large tiled surfaces. - Practice analyzing grid-based mathematical structures through step-by-step written exercises. - Discover how discrete mathematics bridges the gap between simple games and mathematical physics. We begin with basic terminology and classic puzzle formulations before introducing the algebraic and probabilistic tools used in modern research. You will work through clear, written explanations and structured mathematical proofs at your own pace. This course is designed for curious beginners, recreational math enthusiasts, and undergraduate students. No advanced mathematical background is required, as we build all concepts from the ground up.
