那大概属于习惯了或者追求特权,要做人上人的那类。我觉得对正常人来说,和一群跟自己差不多的人在一起似乎更加有舒适感吧。个人感觉,交流起来相对容易,更多时候甚至话没有说完对方就明白了。这样的交流给人一种愉悦感。我不觉得被人顶礼膜拜,到哪里都要前呼后拥是一种令人愉快的体验。

@fangshimin.bsky.social The Fields Medalist Yu Deng of University of Chicago had written a lesbian-themed novel in which one of the two main characters (both lesbians) won the Fields Medal as a women. It is finished before the year when Maryam Mirzakhani became the first female Fields medalist.

有人在方舟子的评论区说数学是最接近于神的东西。我回应说表示异议,其中提到“数学是人类认识世界的一种方式”。最近看懂王虹的一个视频,也提出这个看法。当然,未必她这么看就可以作为一种逻辑上的依据。但是至少表明数学界还有别人有同一点看法。掉书袋说一句“吾道不孤“似乎也没有错。但是很快有人回复,认为并非如此,要点是认为数学是认识世界的工具,而非方式。我虽然回复了,但还是觉得有必要从正面阐述何以这样认为。那么首先就要解释一下这么说的确切含义。

At Trump's inauguration, Melania dressed in all black as if she was attending a funeral. Does this symbolize the end of democracy in the US? I suppose that she did it inadvertently. Or did she?

"Even the story of his near-murder, his tragi-farcical trials, and his ordeal in the penal colony is told with humor—and humanity." Navalny's refusal to knuckle under is permanent, now that he's dead, and is still a threat to Putin's regime. www.thebulwark.com/p/even-in-de...

This comes as no surprise b/c the sole purpose of capital and capitalism is to maximize profit. It can do anything for that, bowing to a wannabe dictator is merely one of such examples.

It would be a whole lot better for the US and the world if a woman is the POTUS, be it Kamala, Gretchen, or AOC. They would take the US forward instead of backward into the 19th century, as Trump and his handlers are trying to do, and with successes!

Given the history of police abusing of power, including making up stories and planting evidence to frame victims, it is simply ridiculous to take a single officer's "testimony" as truth and make decisions solely based on a single piece of "evidence"! This system is fundamentally wrong!

搞笑翻译又一例:University of Maryland, College Park成了“马里兰大学帕克分校”。据说“百度”是这么翻译的。这个错误由来已久,至少在97年就有人这么翻译。当时有一本《美国地图册》翻译成“科利奇帕克分校”,至少用了音译,不能算错。Google则翻译成“大学公园”,虽然College翻译成“学院”更合适一些,不过至少知道那是个地方,还不算太离谱。“帕克分校”实在是谬之千里。这个翻译还堂而皇之的出现在机械工业出版社出版的书上(见附图),可见所有相关人员,从翻译到编辑、校对,没有一个人去了解一下究竟是怎么回事。
