René Descartes, with a glowing coordinate grid, teaches mathematics to children in a stylized classroom with a globe and blackboard.

4.1 坐标革命：笛卡尔统一数与形当你在教室里找座位时，会说 “我在第 3 排第 4 列”；在电影院选座时，票根上的 “5排7座”能帮你快速定位；打开手机地图，输入“北纬 30°，东经 120°”就能找到具体地点； …… 这些生活中确定位置的方法，背后都藏着一个伟大的数学发明：笛卡尔坐标系。这个看似简单的“数字定位工具”，曾经彻底改变了人类看待数学的方式，让原本分家的“数”与“形”首次手拉手站在了一起，甚至还悄悄为更深刻的数学思想（比如极限）埋下了种子。上述内容我想配一张插画，请提供思路 See more
