Why do odd numbers always add up to a perfect square? No algebra needed. 👇#math #proofwithoutwords

A room where every wall is a mirror. Light one lamp. Does the whole room glow? Not this one. Penrose's 1958 room is built from two halves of an ellipse. Light from the corridor always crosses the axis between the two foci, so it can never get into the side pods. Move the lamp anywhere in the corridor and the pods stay pitch black. Put the lamp in a pod and the corridor goes dark instead. (Ideal mirrors, point-like lamp. In 1995 Tokarsky did it with straight walls only.) Your turn: put the lamp in the big upper hall. Any dark spots left? 👇

给家里的海信电视做了次大扫除:用 Claude Code 通过 ADB 关掉了 24 个预装服务(数据上报、开机广告、推送、各种用不上的预装),全程截图验证、可一键还原。

创作手记 · 用数学讲创作苦 粉丝增长是一条 S 曲线: 前面很长一段,几乎是平的。 平到你怀疑自己在自言自语。 但数学说:平坦不是停滞,是蓄力。 拐点之前,每一帖都在给曲线攒斜率。 最残酷的数据是: 大多数人放弃的时间点, 离拐点只剩一周。 #创作手记 #数理之美

如果苏轼是一只股票? 一年一根K线:1057 进士及第“上市”,1079 乌台诗案暴跌 76%,元祐年间V型反转到礼部尚书,绍圣以后一路被抛售到海南儋州。 最好的作品《赤壁赋》,偏偏写在股价谷底。临终前他自题画像:“问汝平生功业,黄州惠州儋州。”仕途最低的三段,他说是一生的功业。 (仕途指数为示意,按官阶与处境估算;时间线依据《宋史·苏轼传》与孔凡礼《苏轼年谱》。) 你人生的K线里,哪一根最难忘?评论区见 👇
