Discipline is liberation. – Martha Graham (1894-1991) “Human reason has a peculiar fate in one kind of its cognitions: it is troubled by questions that it cannot dismiss, because they are posed to it by the nature of reason itself, but that it also cannot answer, because they surpass human reason’s every ability.” – Kant (1724-1804), Critique of Pure Reason, p5 旧城有着长长的历史，还留有四四方方的城墙，近些年来修葺一新。新城在落基山脚下，有一条弯弯的河自此转向东流，南冲北突从来没停过。 2026 Canvas security incident In early May 2026, Instructure disclosed that it was investigating a cybersecurity incident involving certain user data, including names, email addresses, student ID numbers, and messages among users. on May 7, Canvas was hacked again; its login page was replaced with a ransomware message by ShinyHunters.

South African Bishop Desmond Tutu once said, “There is only one way to eat an elephant, one bite at a time.” Apple of 50 years: it’s that the people crazy enough to think they can change the world are the ones who do. The misfits. The rebels. The troublemakers. The round pegs in the square holes. The ones who see things differently. Violation of Bell inequality with unentangled photons 徐令予: 在经典直觉中，人们往往认为：物理对象在被测量之前就已经“具有确定属性”，测量只是把这些属性揭示出来；同时，一个地方发生的事情不应立即影响到远处的另一个地方。这两种直觉合在一起，构成了所谓的“局域隐变量模型”：每个粒子的行为由某些隐藏的内部参数（隐变量）预先决定，且信息传播不超光速（局域性）。可以把它理解为：经典物理假定自然界像一台早已写好程序的机器，而贝尔实验表明，这种“预先写好答案”的图景在微观世界并不成立。 ...

book review Read a review on the last days of Sigmund Freud, its sideline goes like: danger surrounded Freud in Nazi-occupied Austria, why did it take him so long to see it? The book by Andrew Nagorski, Saving Freud: the rescuers who brough him to freedom, offered to tackle this question in 1938. Whatever controversy brought by psychoanalysis, Freud knew the dark undercurrent of human behavior and he was critical of the false security offered by our wishful illusions. As an expert of human nature, he was unable to think clearly when his coutry became so unrecognizable around him. These cognition bias are built-in. What is our chance if we are in the similar situation? ...

“Moral worth should be judged not in terms of the naturalness of a trait, but rather in terms of how that trait impacts the wellbeing of everyone affected by it. Thus, violence is natural but bad, medicine unnatural but good.” – Steve Stewart-Williams, The Ape that Understood the Universe 道德与否不应该以某一属性是否自然为依据，而是应该以该属性是否会影响所有人的福祉为据。正因为如此，暴力是自然的却是不对的，医药是非自然的却是好的。

今天的法国总统马克龙和德国总理舒尔茨很像1938年二战之前的英国首相张伯伦和法国总理达拉第，慕尼黑协定将捷克的苏台德割让给德国并没有带来一厢情愿的和平，只是揭开了二战的序幕。 “尽管试着将这种方式称为谈判，但绥靖的味道却难也遮掩。1938年张伯伦和达拉第去慕尼黑见希特勒的教训依然适用：给独裁者想要的并不能阻止他要求更多；那只能让他相信你不够强大，以致不能阻挡他得到他想要的。否则，顺着独裁者的思路，你早在事情伊始之时就该站起来抵抗。“ 国际象棋大师@Kasparov63 在2014年写了这本书《Winter is coming》，正是俄罗斯入侵乌克兰并强占克里米亚之后。
