In this issue, we trace hidden patterns linking prime numbers to mysterious curved surfaces, and watch the ancient legend of Queen Dido unfold into one of geometry’s most elegant optimization puzzles. We wrestle with limits without leaning on L’Hôpital’s rule, chase reflections across parallel mirrors, and play with three-digit numbers that fold into surprising results. From rural fields where labour meets necessity to the abstract arenas of number theory and symmetry, the puzzles gathered here invite both precision and imagination. With fresh challenges, timeless riddles, and clever solutions from past quests, this issue celebrates the restless curiosity at the heart of mathematics.
