Basically I’m suspending the maintenance of the Chinese section of the site, English readers may simply ignore this announcement. So physics.run will be a Chinglish or Enginese or whatever site from today.
The essential reason is, thanks to GPTs and other AI tools, language of math/physics notes has simply become something of no consequence.
同学们，
感谢大家一直以来对 physics.run 的默默支持。
本网站原本设想为一个中英文双语平台，旨在填补一些古早中文教材没能覆盖的空白。然而，尽管两年来站点的内容没有明显的积累与深入，我还是逐渐意识到：逐篇维护高质量的双语内容，在实际操作中极为耗时且不易持续，特别是在笔记普遍采用 Markdown / LaTeX 编排，并涉及大量专有名词时，翻译真的有点麻烦了，大家都很清楚LaTeX全半角字符切换有多蛋疼。
出于对内容质量与维护效率的综合考量，我遗憾地决定：
自本公告发布起，physics.run 将转变为单语言网站，所有笔记将以一种主要语言发布，暂不再提供系统性的双语支持。
近年来 AI 翻译工具的发展使跨语言学书阅读的障碍大幅降低，与此同时，更让人爽的是有大量更加现代的中文物理教材陆续出版，它们在基于现代物理观点、使用现代数学语言的同时，无疑比本站提供的琐碎的内容更加系统和权威。因此，本站日后的运营将更倾向于本人笔记的云备份之用，另外也借此机会感谢读者一直以来对本站内容的各种typo的高度宽容。
再次感谢大家的理解与支持
愿我们都能爽学物理和数学

Dear friends,
Thank you for your continued interest in physics.run.
When this site was first launched, it was envisioned as a bilingual platform (Chinese + English) to make physics and mathematics notes accessible to a wider audience. However, although the content may not have grown in depth or volume as expected, I do have come to realize that maintaining high-quality translations for every post is simply not sustainable — especially when most notes involve a substantial amount of specialized terminology.
After careful consideration, I’ve made the difficult decision:
Starting today, physics.run will operate as a single-language site, and I will no longer be providing systematic bilingual versions of each note.
That said, I still believe language should never be a barrier to learning. I will continue to keep the formatting clean and minimal, relying on standard Markdown/LaTeX syntax so that readers can easily use automatic translation tools or AI assistants (like ChatGPT) when needed. In most cases, copying and pasting the content into a translator yields satisfactory results — a practical solution in this age of advanced tools.
Thank you again for your understanding and support.
Let’s continue our journey through physics and mathematics, together.
