Description

作者: 張鎮華

       圓是自然界與生活上常見的美妙形狀，它是神賜給人類的寶貴禮物，人自古以來就致力於瞭解其性質。要瞭解圓，就要瞭解圓周率，這個反應它的一個重要常數，小學時老師告訴我們圓周率是3.14，長大一點以後精確度提高到3.1416，到後來就用符號記為π。

　　整本書以數學男孩吉拉一生的經歷，串起古今圓周率計算的工作，並適度介紹與圓周率相關的數學。故事起自吉拉和女兒們討論圓周率，轉而回憶吉拉小時的求學經驗。

　　吉拉小學國語老師挑戰他們計算面積，接到初中學習幾何知識配合根號求值解決問題，輾轉到古代人對於圓周率的計算，集其大成者是南北朝數學家祖沖之，他求得的3.1415926是之後一千年內最精確的值。

　　吉拉四姊計算平方數的挑戰，及他高中時對於完全數的迷戀，指向數學上的計算很容易到達人力的極限。吉拉學習電腦的故事逐漸展現，數學知識加上電腦的威力，讓一些人力不能及的計算，完成到前所未有的境界。現代人對於圓周率的計算就是這個浪潮下的一個小浪花，其中2019年日籍女工程師岩尾算到小數點後31.4兆位數是一個旅程碑。
