方谬神探

韦东奕卖书4天后，两套练习册从他的小店消失了。8月22日晚，韦东奕的B站账号页面已经看不到他的小店以及此前上架的两套小学、初中数学解题能力训练练习册。    What better way to figure out a mystery of the ancients than to try it out yourself? That’s what one sailing aficionado from Israel did when confronted with a puzzle from the Christian Bible.,David Gal, a doctoral student in the Department of Maritime Civilizations at the University of Haifa, says he has figured out why the Christian Apostle Paul sailed from Judea to Rome along the southern coast of Anatolia in 60 CE - a route that, to him, wasn’t the most obvious one, since most winds in the Mediterranean are westerlies and Paul was going west.,That year, Paul was sent to the imperial capital to answer to Jewish authorities for preaching the teachings of Jesus of Nazareth, who claimed to have been the Jewish messiah. Most Jews did not accept Jesus’ teachings, and he was tried and executed by crucifixion for blasphemy and subversion in either 30 or 33 CE.,Paul’s journey is recounted in unusual detail in the New Testament book of Acts. The preacher zigzagged his way across the sea, swinging north of Cyprus before heading to the city of Myra (modern Demre) in southern Anatolia. From there, he went west past Rhodes, to Knidos, then south to the southern coast of Crete and west across the southernmost parts of the Ionian Sea. However, he was shipwrecked in Malta and his journey took much longer than anticipated.,“Until recently, we didn’t understand why the Alexandrian grain ship that Paul joined in southern Anatolia, bound for Rome, chose that particular route,” Gal told Haaretz.,The boat, Ma’agan Mikhael II, is a replica of a ship found in 1985 about 2 meters underneath the seabed off the coast of Kibbutz Ma’agan Mikhael in northern Israel, not far from Caesarea. In ancient times, the city was known as Caesarea Maritima or Caesarea Palestine, named after the Roman emperor Augustus Caesar. The replica boat was finished in 2016 and is just one of two ships in the world that simulates a merchant sailing vessel from Before the Common Era (BCE).,By coincidence, Caesarea also happens to be the port from which Paul left on his trip to Rome.,In part, Gal’s study was based on computer modeling, which combined vast amounts of weather data and conducted 5,479 virtual sailing trips along 224 different possible routes from Caesarea to Rome, for a total of 1.2 million virtual sailing trips. However, that wasn’t enough: Gal also took a crew of 10 volunteer sailors out in the Ma’agan Mikhael II to explore the intangible human element of the journey. With just one sail, the ship moves along at a brisk 3.9 miles per hour.,“Only when we sailed on Ma’agan Mikhael II did we understand the real limitations of the ship and the sailors,” Gal told Haaretz. “We found that in many sections of the coast, the breeze doesn’t support this type of movement.”,“They didn’t sail counter to the prevailing wind, but waited for days with a favorable wind in the opposite direction,” Gal concluded. “We found there were such days in a large meteorological sampling. Until now, scholars didn’t examine that but used low-resolution meteorological averages that erase the variance in the wind.”,Gal said he has taken the ship out more than 80 times, sailing as far as Cyprus, and found that the daily wind patterns, in which breezes can blow westward from the Levantine coast, have remained strong after 3,000 years. By navigating those patterns, ancient sailors could have crept up the coast until they found more favorable winds.,“We have data about its performance in all wind conditions and how various currents affect it, and that enables us to conduct a reliable simulation of sailing. With its help, we acquired insights into the way such a ship is operated; we had a better understanding of how four people can sail from Greece to here and back,” he said.。不过，目前相关商品链接仍能在B站搜索到，销售店铺是“韦东奕图书”，销量还在继续增加。截至8月23日上午，《小学数学解题训练1—6年级超详细答案视频讲解》已售出超过2万本，相关初中产品也售出1万多本。这套练习册覆盖1至9年级，每个年级一套、每套3册。

二 | 此前售价分别为39.8元和49.8元。按照公开销量和标价粗略计算，两类产品对应的成交金约130万元，但这并不等同于实际收入。

店铺销量截图这场销售发生在4天前。

三 | 8月18日晚，韦东奕时隔一年更新B站账号，发布视频《一道有趣的数学题》。

四 | 视频中没有本人出镜，只展示了一道小学四年级数学题及解题方法。与此同时，他的B站小店上新了两套数学解题能力训练练习册，商品页面标注“韦东奕主编”，并印有他的名字和照片。

五 | 北京大学已向媒体确认，上述B站账号确实为韦东奕本人账号。练习册出版社龙门书局也对媒体表示，这套图书确实由韦东奕本人亲自主编，内容偏向培优方向，本周刚刚上线，目前龙门书局官方账号以及韦东奕个人账号均有售卖。

六 | 不过这两套练习册还有其他销售入口。8月18日，韦东奕堂哥韦晶洲、堂姐韦丹青的抖音账号，同步上线了相关数学题视频，并挂出了两套练习册的购买链接。商品店铺同样是“韦东奕图书”。

韦东奕图书营业执照截图公开的营业执照显示，“韦东奕图书”所属公司，是杭州奕数文化产业发展有限公司，成立于2026年5月22日，法定代表人为曹恩铭，注册资金100万元，业务类型为零售。其经营范围包括出版物互联网销售、出版物批发、出版物零售，以及教育咨询、技术开发、数字广告发布、文具用品零售、日用百货销售等。事实上，教师、科学家出版教材、科普书和习题集，是知识传播中常见且成熟的一种方式。知名华裔数学家、菲尔兹奖得主陶哲轩，早在15岁就出版了《陶哲轩教你学数学》，介绍解题策略和数学思维。

七 | 因此，在该练习册上架后，不少网友表示支持，认为这并无不妥。但外界也出现了关于韦东奕本人是否主动参与此次卖书的猜测。自走红以来，在大众认知里，韦东奕是一个专注数学、生活俭朴、与互联网保持距离的数学家。媒体曾报道，他几乎不看电视、没有微信，除了查资料很少上网，爱听收音机，最喜欢的事情就是做数学题。

八 | 2025年6月，他在抖音、B站、小红书等平台开通个人账号，迅速积累千万粉丝，但此后长期没有更新。从公开信息看，围绕这两套练习册，除了出版社官方销售，的确出现了个人账号、亲属账号以及相关公司参与内容发布和商品销售的情况。不过，目前的公开资料还不足以确认这些主体之间的具体关系，也无法判断韦东奕本人在其中扮演什么角色。至于商品为何从韦东奕的B站小店消失，韦东奕本人也尚未公开回应。记者：杨智杰编辑：闵杰运营编辑：王琳
