1哈密顿是英国著名的数学家,他儿童时代便已通晓八种语言;12岁已经读完了拉丁文的《几何原本》;22岁便当上了大学教授。在数学史上,他曾以发明“四元数”而青史留名。他除了喜欢散步、去咖啡馆,还常常光顾集贸市场。2有一天,他在市场里买到了一个正十二面体的模型。这个模型有12个面,20个顶点和30条棱,每个面都是相同的正五边形。哈密顿非常喜欢这个模型,他对其爱不释手,反复把玩。 1 Hamilton was a famous British mathematician who had become acquainted with eight languages ​​in his childhood. He had finished reading the Latin “geometry” at 12 and was a university professor at 22. In the history of mathematics, he used to invent “quaternion” and the history of the world. In addition to his favorite walk, go to cafes, but also frequented bazaars. 2 One day he bought a model of a dodecahedron in the market. This model has 12 faces, 20 vertices and 30 edges, each of which is the same regular pentagon. Hamilton loves this model, he put it down and played repeatedly.
