Eileen Power 的《Wool Trade in English Medieval History》、Geary 的《Before France and Germany》、Dörrie 的《100 Great Problems of Elementary Mathematics》、佐贺纯一的《极道忏悔录》（Confessions of a Yakuza），还有一本我为了插图买的关于 Klee 的烂书。如果你想了解硅谷，我倒不推荐 Saxenian 的书。Lecuyer 的看起来更好一些。
Eileen Powers' Wool Trade in English Medieval History, Geary's Before France and Germany, Dorrie's 100 Great Problems of Elementary Mathematics, Saga's Confessions of a Yakuza, and a terrible book on Klee that I bought for the illustrations. If you want to understand Silicon Valley, I would not recommend Saxenian's book. Lecuyer's seems better.

那是 Heinrich Dörrie 的《100 Great Problems of Elementary Mathematics》中的一道题：https://www2.washjeff.edu/users/mwoltermann/Dorrie/MaxMinPro...
