西游记后传

二 | 北京大学相关工作人员已经出面证实，该账号确实为韦东奕本人运营，上架的练习册由他亲自牵头主编，另有9位业内专业编委共同参与了整套内容的打磨编撰。这本练习册上架没几天，仅单一主流电商平台的销量就突破了2万件，全平台累计销售额已经达到数十万元，不少学生和家长冲着韦东奕“北大数学大神”的口碑直接下单，希望能跟着顶尖学者总结的思路快速提升数学成绩。这件事曝光后很快就在全网引发大范围讨论，网友的态度直接分成了几个完全对立的阵营。有不少人力挺这种知识变现的模式，认为顶尖数学家下沉做基础教育内容，是普通中小学生的福气，靠专业能力赚钱完全无可指摘。

三 | 也有一部分人觉得韦东奕这种级别的顶尖科研人才，本该把全部精力投入到前沿数学研究中，花时间做中小学教辅属于纯粹的大材小用。    The United Auto Workers union has once again escalated its strikes against big Detroit automakers, this time adding a factory that makes Ram pickup trucks for Stellantis.The union says that 6,800 members walked out Monday morning and shut down the Sterling Heights, Michigan, Assembly Plant, a huge profit center for the company.The newest strike action comes just three days after union President Shawn Fain reported progress in talks with General Motors and Stellantis but said the companies will have to make better offers. No progress was reported with Ford, which last week said it had the best offer of the three.The union went on strike Sept. 15 at one assembly plant from each company. About 40,800 workers are now on strike against all three automakers. The strikes, now in their sixth week, cover seven assembly plants and 38 parts warehouses. About 28% of the union's work force at the three company's are now on strike.General Motors, which increased its offer last week, and Ford were spared in the latest escalation. At first the union avoided striking at pickup and large SUV plants, which at all three produce vehicles that make the most money for the companies. But that changed two weeks ago when the UAW took out a giant Ford heavy-duty pickup and SUV plant in Louisville, Kentucky. In its statement, the union said that offers from Stellantis, formed in the 2021 merger of Fiat Chrysler and France's PSA Groupe, lag Ford and GM despite the automaker having the most revenue and highest profits of the three.Stellantis has the worst offer on cost of living raises, how fast workers move to the top of the pay scale, temporary worker pay, converting temps to full time, and other issues, the union said.By taking down the Stellantis factory, the union is signaling Ford and GM to improve their offers, Wedbush analyst Dan Ives said. Last week it appeared a deal might be in the works, but Fain said Friday that the companies will need to pay more.“It takes a potential deal that appeared on the table -- at least for now -- off of it,” Ives said, predicting the the union will announce new strike locations later this week. "There could be some tough talks ahead,” Ives said.On Friday, Fain said Stellantis and GM have made wage offers that matched Ford’s 23% over the life of a four year contract. But, speaking in his characteristic sharp tones, the union president insisted that the companies can go further.“We’ve got cards left to play, and they’ve got money left to spend,” Fain said.While Fain said the companies keep touting that they’ve made record offers to the UAW, he said they’re insufficient to make up for how much ground workers have lost during the past two decades. Each time the automakers make an offer, Fain said, they insist it’s the best they can do, only to return days later with a better offer.“What that should tell you,” Fain said, is that “there’s room to move.”。

四 | 还有不少拥有十数年教龄的资深中学数学教师特意站出来提醒，韦东奕的解题思路和思维逻辑本身更适配数学天赋突出的孩子，普通孩子没必要盲目跟风囤书硬啃，很容易跟不上节奏反而打击学习信心。目前韦东奕本人还没有针对网上的各类争议作出任何公开回应。
