一、杨振宁的演讲，最触动我的两句话 杨振宁先生去世的消息刷屏。我重温了多年前他在中科大的演讲，还是佩服得五体投地，其中的两句 话，一直深深地触动我。 第一句，是他在西南联大读书时领悟到的。当时，他第一次看到圆周运动的加速度方向指向圆心，而非 运动方向，他由此理解了向量。这对他后来的学术产生了重要的影响。他由此悟到： "当你发现一件事情违背你的直觉时，要重视，那里可能隐藏着重大发现。" 第二句，是他回国后的观察。他在芝加哥大学和导师泰勒（Taylor）一起时，通过观察和讨论现象寻找 理论，而回到北京后，发现国内大学过度重视四大力学的教学，多为从理论推导现象。两相对比，他提 出： "中国教育的问题，是演绎法用得太多，归纳法用得太少。把以'知之为知之，不知为不 知'做得太刻板，会忽视发觉"不知"里面的机会"。 这两句话看似无关，但我觉得它们指向的，其实是同一个问题——人类的思考，不仅需要逻辑，也需要 直觉；不仅要演绎，还要归纳。而思考，对于人们的工作和生活，都至关重要。 二、直觉从哪里来 杨振宁提到"违背直觉"的时候，没有展开介绍直觉的来源。在神经科学和心理学看来，直觉并不是"感 觉"或"第六感"，而是大脑潜意识层 ...

Core Viewpoint - A group of 55 Chinese consumers has submitted a complaint to the State Administration for Market Regulation, accusing Apple Inc. of abusing its market dominance in China through various monopolistic practices that harm consumer rights [1][2]. Group 1: Allegations Against Apple - The complaint alleges that Apple forces Chinese consumers to use its In-App Purchase (IAP) system for digital goods and services, prohibits developers from directing consumers to alternative payment methods, and imposes unfairly high commissions of up to 30% [5][7]. - The core demands include an investigation into Apple's alleged illegal activities and a mandate to allow third-party payment channels and app stores in China [3][4]. Group 2: Specific Requests for Action - The consumers request that Apple be ordered to open third-party payment channels, allowing developers to guide consumers to external platforms without incurring any commission [8]. - They also demand that Apple permit access to iOS applications outside of the App Store, including third-party app stores and sideloading options, without charging any fees [9]. - Additionally, the complaint calls for a reduction in the commission rate for in-app purchases to be lower than the most favorable rates in other countries [10]. Group 3: Comparative Analysis - The complaint highlights that Chinese consumers face "country-specific discrimination," as they are unable to access third-party payment options and are subjected to the highest commission rates globally [11][13]. - It cites recent legal developments in the U.S. and EU, where courts have mandated Apple to provide payment options and reduce commission rates, contrasting this with the situation in China [12][14]. Group 4: Financial Impact on Consumers - In 2024, Chinese consumers are projected to pay $6.44 billion in "Apple tax," second only to the U.S. at $14.8 billion, and surpassing Europe at $4.8 billion [15][30]. - The complaint calculates that the "Apple tax" constitutes 10% of Apple's revenue in China, compared to 8.8% in the U.S. and 4.6% in Europe, indicating a heavier burden on Chinese consumers [15][30]. Group 5: Global Legal Actions - The complaint notes that over ten countries, including Japan, South Korea, and Australia, have initiated legal actions against Apple for similar monopolistic practices [18][31]. - Japan's Fair Trade Commission has announced plans to force Apple to open third-party transaction models by December 2025, marking a significant shift in the Asian market [19][31].

"牺牲者也要反思吗？" 近期上映的电影《爱的暂停键》给观众带来某种情感层面的不适。电影中二婚四娃、无力专注工作的女主角 Maria，在婚姻与育儿的琐碎中独自挣扎，去 趟超市都状况百出，还因银行余额不够窘迫到打电话借钱付款。 她感觉自己付出了所有，却换来了丈夫的疏远，指责她有"情绪管理问题"；两个大孩子对母亲疏于照料而不满，不愿忍受她的坏脾气，宁愿搬走和她的前 夫生活。 当丈夫最终提出离婚时，她的世界崩塌了——"明明该感到委屈的人是我啊，我什么都牺牲了！" 直到走进了心理咨询室，她才发现原来"自己对自己的生活也负有责任"。她早已深陷于一种"受害者叙事"而不自知，她常常使用情绪暴力绑架亲人，会通 过让丈夫产生"内疚"来控制他不要离开自己。 在女主身上，很容易看到我们周边不少人的影子。 电影看似是一场婚姻矛盾，实则是女主从"怨妇"到觉醒者的内在成长。 故事的动人之处也正在于此。这呼应着电影的英文名"Loveable"，比爱更难的是，普遍存在着的"被爱的不耐受"——正如热评所言"从未被真正爱过的 人，一生都在试图证明爱的不可靠。" 在媒体采访中，导演莉莉娅说，"最重要的一个转折点是她倾向于去扮演亲密关系中的受害者角色 ...
