快科技8月22日消息，此前一直很少在公共社交平台露面的韦东奕，近日突然在个人账号更新了多期数学专项解题视频，还同步上架了一本面向中小学生的数学练习册。    Earlier in the day, Johnson announced his resignation, stressing that he would continue to fulfill the role of party leader and prime minster until his successors are appointed.,"Note this follows the collapse of Macron's government in France as well as other EU countries. Many more will likely see changes ahead to include Germany and Italy," Rasmussen said.,He believes that all major Western leaders, including in the US, "need to be replaced" before the world will see "the potential for improvement.",Johnson’s resignation itself came as no surprise, according to the expert. "We also have seen diminishing support for Johnson's conservative party as well," he noted.,From Getting Brexit Done to Sleazy MPs: The Rise and Fall of Boris Johnson12:17 GMT,Rasmussen expressed overall concerns that the West is moving "on a very dangerous path" both economically and militarily.,"Fences will mend over time but not until western leaders are replaced with those that care for their own people and countries and respect all countries' sovereignty. We are moving in uncharted waters and the next several years will be challenging but there is still hope for a brighter future for all," he said.,Last week, Christopher Pincher resigned as deputy chief whip of the UK's Conservative Party after being accused of sexual misconduct in one of London's private members club. A number of politicians claimed that Johnson appointed Pincher to the post despite knowing about sexual misconduct allegations. On Tuesday, Johnson apologized and admitted, "in hindsight it was the wrong thing to do.",The scandal has led to a string of resignations, with dozens of officials stepping down from Johnson's government, including such key figures as Health Secretary Sajid Javid and Chancellor of the Exchequer Rishi Sunak.,Johnson Has Turned Tory Leadership Into ‘Poisoned Chalice’ for His Replacement, Observers Say12:19 GMT。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。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。

二 | 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。
