清初的剃发易服不到十年就完成了，以致旗袍成了华人的代表服饰。清末开始的民主化进程直到现在还是老样子。
“信教”是被动的，可以威逼利诱。维持一个民主体系，除了需要大众主动参与，还需要精英们自慎自审。好了，都搭顺风车；差了，护住自己的一亩三分地。这套体系就没法维持

想明白了，是最后一步概念转化错误。算出了右边的后期水面低，维持有水时间更长，但是转化为“快”😅。就是那种睁着眼睛说反话，自己还不知道的状态
有答案吗？第二个不知道为什么是7。另一个错的是两个水桶？难道左边的快？一般，流速等于相应高度的水自由下落到底部的速度

著名数学家陶哲轩刚刚发表了一篇评论，批评特朗普政府对美国科学界的全面攻击。评论的副标题是：The "Mozart of Math" tried to stay out of politics. Then it came for his research。——大意是： 数学神童不想惹政治，政治却向他的研究开了刀 (让我联想起昔日中国 “白专典范” 的遭遇，特朗普的美国倒退得多远，由此可见一斑)。最近一段时间，除美国外，时不时也听到其他国家右翼得势的消息，相应的政治人物则被称为 “某国的特朗普”…… 字数超标，全文请到我主页阅读：

Socialism is what they called public power.
Socialism is what they called social security.
Socialism is what they called the growth of free and independent labor organizations.
Socialism is their name for almost anything that helps all the people.

A lovely place. We will move out soon.
Happy to be part of this! It’s promising to improve land modeling with EEO.

Hello bluesky! We'll be posting updates on the UK Earth system model developments, how we are using it, papers and how we collaborate with EU and international partners. If you have any questions, I'll try to field them😅

I made 11,160 model runs with our BiomeE in this paper. It was done for many times, with different model settings to test model assumptions and parameterization. Eventually, we only chose one set of the runs in the results. Toy models are useful!
