Why I write我为什么写
I hope each article helps a reader understand a question or notice a detail they might otherwise miss. This notebook records how I work through explanations, test my understanding, and observe everyday life, so an exploration can be followed, revisited, and discussed.我希望每篇文章都能帮助读者看清一个问题，或注意到曾经忽略的细节。这里记录理解事物原理、检验判断与观察生活的过程，让一次探索可以被读懂、回看和继续讨论。
How I work through an idea怎样把一个问题想明白
Begin with a concrete question, phenomenon, or detail. Show the evidence and reasoning, using words, images, or experiments where they help. Record what has become clearer and what remains unresolved, then revise that understanding through new evidence and conversation.从一个具体的问题、现象或细节开始，交代依据与思考过程，选择最能帮助理解的文字、图像或实验。写下已经弄清的部分，也留下尚未解决的问题，在新的证据与交流中继续修正。
Sources and conversation来源与交流
Technical notes link to their sources and record assumptions and reproduction conditions. Questions and corrections belong with the article, where the explanation can be improved in context.技术笔记链接原始来源，记录假设与复现条件。文章下的讨论区可以提问、纠错，把解释中尚未说清的地方继续补全。
