編輯備註 丹尼爾．凱曼 2005 年的長篇，讓兩段人生並行展開：亞歷山大．馮．洪堡在 1799 至 1804 年的美洲考察中攀登火山、溯奧利諾科河而上；卡爾．弗里德里希．高斯則幾乎足不出哥廷根，用數學丈量世界。兩人直到 1828 年才在柏林相遇，成了兩個對彼此毫無耐心的年老名人。全書幾乎都以間接引語與冷面反諷寫成，成為戰後最暢銷的德語小說之一；2012 年由德特勒夫．布克改編成電影。
關於本書
Measuring the World is a novel by German-Austrian author Daniel Kehlmann, published in 2005 by Rowohlt Verlag, Reinbek. The novel re-imagines the lives of German mathematician Carl Friedrich Gauss and German geographer Alexander von Humboldt—who was accompanied on his journeys by French explorer Aimé Bonpland—and their many groundbreaking ways of taking the world's measure, as well as Humboldt's and Bonpland's travels in America and Humboldt's meeting with Gauss in 1828. One subplot fictionalises the conflict between Gauss and his son Eugene; while Eugene wanted to become a linguist, his father decreed that he study law. The book was a bestseller; by 2012, it had sold more than 2.3 million copies in Germany alone.
