你能否解決那堡壘難題嗎？——亨利·皮喬托

壞消息：你最大的敵人已經來到城門下。你這個羽毛初長毫無經驗的王國，守護著世上僅存的小型恐龍生物。對你而言牠們很神聖。對其他人而言牠們是食物。最鄰近的三個民族國家聯合起來要擊碎你的城牆，把這些生物吃光。你能否在攻城武器送來之前，為你的王國做好防禦工事？讓亨利‧皮西歐托來示範怎麼做。［由 Artrake 工作室伊戈爾·科里克執導，艾迪生·安德森講述］。 

A kingdom protecting the world's only herd of tiny dino creatures faces an alliance equipped with destructive siege engines. The only hope is to build a wall segment of the one length that no combination of enemy weapons can destroy. Using an approach inspired by the sieve of Eratosthenes, a method first used to find primes in ancient Greece, the solution reveals that a 43-meter wall is impregnable. This blend of logic and history transforms a life-or-death puzzle into a masterclass in mathematical thinking.
