二 | Govinda, the hugely popular comedy star of the 90s known for films like Coolie No. 1, Hero No. 1 and Raja Babu, was often criticised for reportedly arriving late on film sets at the peak of his career. While the label followed him for years, the actor has maintained that it was never about a lack of discipline. The topic has come up again after Madhuri Dixit recently said she was thankful, she never worked with actors who were known for being late. In an interview with Mid-Day, Madhuri was asked about her experience working with actors who had a reputation for tardiness, including Govinda. The actor clarified that she never faced such issues and shared that punctuality was never a problem on her sets. “Thank God I worked with people who were always on time. They were Anil Kapoor and Jackie Shroff. With me, it never happened,” Madhuri said. Earlier, Govinda had spoken openly about this perception during a conversation with Mukesh Khanna, explaining that his work ethic was inspired by Dilip Kumar. He said being punctual, for him, meant being mentally prepared before stepping on set. “I never used to arrive on time on set. I was a follower of Dilip Kumar sahab. I didn’t believe in being late and all. I used to first set my rhythms right. Jab tak mere sur taal nahi set ho jaaye, main set pe nahi pahuchta tha,” Govinda said. The actor also recalled how Dilip Kumar helped him during the busiest phase of his career, when he had dozens of films running simultaneously. “I would have 40–49 films on the floor. I would travel from one set to another. Main anpadh aadmi in film logon ke haath mein lag gaya, agar Dilip Kumar sahab nahi milte mujhe toh ye log mar dete mujhe. He made me refuse around 25 films. I told Dilip Kumar sahab, ‘I will have to return this money.’ He told me, ‘I will lend it to you, but quit these films,’” Govinda shared, adding that the advice helped him regain control over his career and life.

三 | 在一定条件下，量子场论退化成量子电动力学。第3.5层：量子电动力学，1954版杨-米尔斯理论维度：4维在低能和非相对论极限情况下，量子电动力学退化成麦克斯韦方程。本身就是麦克斯韦扩展出的杨-米尔斯理论当然也能退化成麦克斯韦方程。第4层：麦克斯韦方程维度：3+1维（这个大学生通常假装表示懂。）众所周知，杨-米尔斯理论中的杨指杨振宁。对比上面两个降维路径，我们当然认为杨老绝对应该是可比肩爱因斯坦宗师级的人物，但是… 可惜…… 最早的1954年版杨-米尔斯理论预测传递力的粒子质量为0，但二十年前汤川秀树就证明介子质量不是零，所以杨-米理论被一杆子打入冷宫。关键是杨老自己也解释不了为什么，虽然从数学上看这些偏微分方程是美妙的。如何将经典杨-米尔斯理论应用到量子场论，是个极其复杂的数学过程。

四 | 在1970年代上半叶，科学家们终于发明了一系列高深的数学工具，他们开始相信杨-米尔斯理论的正确性，并建立了夸克模型和预言了胶子的存在，这替代了汤川那宏观层面的介子。到1979年无质量的胶子被对撞机发现，杨-米尔斯理论彻底“复活”并戴上皇冠。

五 | 但是，老版本的杨-米尔斯理论描述的是一个“经典”宇宙中的场--平滑、连续、确定性的。把经典场公式量子化，在数学上极为困难。复活该理论的物理学家创造了一些黑魔法工具来实现其在量子尺度的可计算性，但是这都建立在未被证明的数学结构上。到今天为止，构建量子化杨-米尔斯的数学基础仍不成功，它是被克莱研究所悬赏百万美金的千禧年难题中号称最难的一个。从类似角度看，我个人觉得同样可惜的是希尔伯特。希尔伯特以一己之力做出完整广义相对论的数学解和量子力学的数学基础（希尔伯特空间）。虽然他在数学界是绝对的宗师中的宗师，但在大众眼里根本不知道他是谁。
