In this issue, we follow the extraordinary journey of George Green, a self-taught miller whose quiet brilliance reshaped physics and calculus with a theorem still echoing today. We probe functions whose derivatives conceal harmonic sums, and weigh the subtleties of conditional probability when dice favor sixes under special conditions. A layered sequence beckons with telescoping beauty, while a weary postman discovers that inefficiency may be the key to his perfect workout. From hidden harmonies in analysis to the playful logic of optimization, the puzzles here invite readers to walk both the shortest and the longest paths that mathematics lays before us.
