北大数学天才，回国任教6年后果断赴美，3句话揭开学术界遮羞布首发2023-12-21 12:16·议史纪#2023年度创作挑战#在阅读此文之前，麻烦您点击一下“关注”，既方便您进行讨论和分享，又能给您带来不一样的参与感，感谢您的支持！我国是人才大国，近些年越来越多的科研学者在国际上收获了无数荣誉与认可，对于这些人才，该如何留住他们是最为关键的，很多人因为国外各种诱人的条件选择了去往国外，更有不少人在毕业后就直接留在了那里。总体而言我国的人才流失现象还是较为严重的，然而有一位北大数学天才，科研界的新星，却在毕业后选择了归国报效祖国，不过仅仅6年，这位数学天才许晨阳又果断辞去了国内的职务，选择赴美。这一切的背后究竟隐藏着什么原因呢？也许许晨阳在离开前留下的三句话能够为我们解惑。名副其实的数学天才许晨阳从小到大都是不折不扣的学霸，甚至可以被称为天才，1981年他出生于重庆一个知识分子家庭，虽然家庭不算大富大贵，但是父母对许晨阳的教育很是重视，也愿意为了他的学习付出。在小时候，许晨阳就展现出了对于数字的敏感，很多人觉得枯燥乏味的数学题，许晨阳却觉得很有意思，甚至有时候能盯着一道题看一整天，不哭也不闹。在父母发现了他在数学方面的天赋之后，也开始有意的培养这方面的能力，可以说许晨阳的成功可谓是天时地利人和，不仅自己有天赋，轻松学一遍就能超过多数人苦读，他的父母也擅长教育，及时的培养他的能力。中考时，许晨阳毫不意外的考入了当地的重点中学——成都树德学院，这是四川省的首批重点中学，几乎汇聚了四川重庆所有的尖子生，在这所中学毕业的学生最终都能在自己的领域大放异彩。尽管在竞争如此激烈的校园里，许晨阳也丝毫没有逊色，更没有泯然于众人，反而变得愈加耀眼，因为是重点中学，所以许晨阳也有了更多的机会站上更大的舞台，提高自己的数学水平。在高中时许晨阳就多次参与数学竞赛，一路过关斩将，几乎是每一场都能获得优异的成绩，随后四川省数学代表队看中了他，将他纳为自己的队员。在1998年，许晨阳又参加了中国数学奥林匹克冬令营，这是国家级的竞赛，汇聚了全国人才，然而许晨阳又再次力压众人，获得了金牌，成功入选中国数学队。面对不可多得的数学人才，多所名校都在默默的关注他，准备给他递出橄榄枝，最终北京大学第一个出手，给他送去了入学通知书，在很多人还在苦恼高考的时候，许晨阳就已经保送到了北京大学。许晨阳的天才还表现在他大学期间仅仅用了一年时间就学完了本科四年的全部必修课程，很多人以为在中国的顶级名校，许晨阳也许会被比下去，但是他用自己的惊人表现震惊了无数校友和老师。大家都在为这样一位新星而赞叹不已，期待着他能够为中国数学界的发展做出一番事业，许晨阳醉心学术，在本科期间就多次发表高质量论文，等到他硕士毕业，发布多篇核心文章时，这位数学天才仅仅23岁。2008年，普林斯顿大学向许晨阳递来了入学通知书，许晨阳同其它三位校友坐上了飞往美国的飞机，准备自己的博士阶段学习，四年的深造令许晨阳成长了不少，他在数学领域也有了更为深刻的造诣。博士毕业后，许多出国留学的学生都会面临着人生的岔路口，到底是归国发展还是接受美国的诱人条件留下来，据说当时美方为了留住许晨阳这位数学天才，甚至承诺会给许晨阳绿卡。与他同去的几名同学在毕业后，接到了名校任教的邀请，选择了留在美国工作生活，但是许晨阳却一直没有定下来，他的心中对中国的科研发展是有执念的，也想要为祖国的发展贡献出自己的一份力量。终于在2012年，这位备受瞩目的数学界新星选择了归国，此时的他不过三十出头，但是北京大学破格提拔他为教授，期望他能在北大的校园里做出一番成绩。教书育人对许晨阳来说并不是最主要的任务，但是他仍然十分用心备课，用简单易懂的话术将自己所学所思传授给学生们，在下课后也会经常邀请学生主动向他请教问题，不要羞涩。在教书之余，许晨阳将几乎全部的时间都用在了科学研究上，多次参与核心科研项目，所发布的论文也被收录进核心期刊，对中国的数学科学发展起到了一定的推动作用，各类青年科学家的奖项也是拿到手软。前辈看重他，后辈倾佩他，可以说许晨阳的人生是十分风光的，未来也是一片坦途，但是仅仅过去了六年，许晨阳便辞去了北大的职务，选择了再次出国任教，原来麻省理工一直未放弃对许晨阳的聘请。在经过多方考虑之后，他选择了接受，随后一个人回到了美国，成为了麻省理工的终身教授，一时间网上流言四起，大家对于这位年轻的数学天才的态度从热情变为了困惑，甚至是质疑。揭开学术圈的遮羞布有人说，许晨阳最终还是选择了留在美国，他当初回国的举动都是作秀，许多人想法受到了动摇，觉得许晨阳同那些贪图享乐的人没什么两样，对于这些质疑声，许晨阳最终还是出面了，他只说了三句话，便揭露了国内学术圈的乱象，引发人们的深思。在许晨阳看来，中国的学术界存在着三大乱象，一为学术腐败，要知道我国每年拨发给科研项目的经费并不算少，但是这些钱真的到了科研人员的手中吗？在看不见的地方，一些别有用心之人会侵吞科研经费，严重的阻碍了科研项目的顺利进行，很多人更是会通过金钱贿赂或者权力来“买”论文和证书，众所周知的娱乐圈“学霸”翟天临便因为在直播间说自己不知道“知网”是什么，而被网友质疑他的学位是否真实。但如果他没有开这场直播，那么是不是这一辈子都不会被发现，然后继续享受着学霸人设带给自己的光环和优待？其实这种现象并不算少，伪造简历、虚假实验，这些行为在学术圈屡见不鲜，许晨阳便是为此深感头痛。学术腐败盛行，没有人专心科研，只想着如何赚钱如何获利，这对一个一心都是学术研究的学者来说是一次沉重的打击，许晨阳很多时候会感到无力，对待这些行为凭借他一个人的力量也阻止不了。这第二个乱象便是中国的学术界论资排辈的现象十分严重，只因为有着高级职称或者头衔，许多所谓的前辈便开始装腔作势，甚至打压后辈，希望通过这些威胁能让后辈们心甘情愿的“孝敬”他，奉承他。因为很多人或者机构并不是真正的关心科研，如果一篇论文发布了，很多人最先关注的并不是论文的主要内容，反而是作者的头衔和地位，这也就导致了很多有能力的新人在发布论文时必须要找一位前辈的名字排在第一作者的位置上，而奉献了大头的后辈却只能排在第二作者的位置上。因为只有这样，才能够使自己的研究受到重视，但是在论文被收录或者引起讨论之后，所带来的成就也是前辈们的功劳，这也就导致了职称高的人会愈来愈高，而这些科研界的新人却备受打压，甚至失去了信心与动力。许多新人在正式开始自己的科研生活之前，必须要学会“拍马屁”，只有讨好那些所谓的前辈，他们才肯带着自己，否则在这个处处打压新人的学术界很难有出头之日，所以衡量一个人是否能够重用的标准便从真才实学变为了酒桌上的一杯杯烈酒。许晨阳并不是个擅长与人打交道的人，但好在他的能力与地位也不需要他委曲求全自己，但是也只能做到这种程度，如果想要以一己之力改变，那是十分困难的。这第三便是学术评价体系不合理，相对于论文的质量，在很多时候，我国都更看重论文的数量，这也就导致了许多科研学者为了提升自己的职称，从而选择许多简单重复的研究进行分析，只为了满足数量要求，却忽略了创新，导致科研成果停滞不前。更有不少人选择将自己的研究“切割”，发布多篇不同的论文在不同的刊物上，只为了能够凑齐这些高级别刊物的“大满贯”，在被利益驱使的情况下，许多科研学者并不能专心研究，反而想着怎样投机取巧。许晨阳的三句话揭开了学术圈的遮羞布，再对比美国所提供给他的一系列研究需要，我们也就能够理解这位数学天才的选择了，他不希望科学被利益所玷污，选择了更为纯粹的一条路。这起事件势必要引起我们足够的重视，学术圈的改革势在必行，我们绝不能放任不管，导致更多的人才流失！由于平台规则，只有当您跟我有更多互动的时候，才会被认定为铁粉。如果您喜欢我的文章，可以点个“关注”，成为铁粉后能第一时间收到文章推送。

We demonstrate unexpected OOP ferroelectricity and piezoelectricity in untwisted, commensurate, and epitaxial MoS2/WS2 heterobilayers synthesized by scalable one-step chemical vapor deposition. We show d33 piezoelectric constants of 1.95 to 2.09 picometers per volt that are larger than the natural OOP piezoelectric constant of monolayer In2Se3 by a factor of ~6. We demonstrate the modulation of tunneling current by about three orders of magnitude in ferroelectric tunnel junction devices by changing the polarization state of MoS2/WS2 heterobilayers. Our results are consistent with density functional theory, which shows that both symmetry breaking and interlayer sliding give rise to the unexpected properties without the need for invoking twist angles or moiré domains.huaxueChemistryHydrotrioxide (ROOOH) formation in the atmospherezaidaqizhongxingchengdeqingsanyanghuawu（ROOOH）▲ zuozhe：TORSTEN BERNDT, JING CHEN, EVA R.

Previously, it has been speculated that they are formed in the atmosphere through the gas-phase reaction of organic peroxy radicals (RO2) with hydroxyl radicals (OH). Here, we report direct observation of ROOOH formation from several atmospherically relevant RO2 radicals. Kinetic analysis confirmed rapid RO2 + OH reactions forming ROOOH, with rate coefficients close to the collision limit. For the OH-initiated degradation of isoprene, global modeling predicts molar hydrotrioxide formation yields of up to 1%, which represents an annual ROOOH formation of about 10 million metric tons. The atmospheric lifetime of ROOOH is estimated to be minutes to hours. Hydrotrioxides represent a previously omitted substance class in the atmosphere, the impact of which needs to be examined.Dynamic interplay between metal nanoparticles and oxide support under redox conditionsyanghuahuanyuantiaojianxiajinshunamiliziheyanghuawuzaitizhijiandedongtaixianghuzuoyong▲ zuozhe：H.

Transmission electron microscopy revealed that the strong metal-support interaction (SMSI)–induced encapsulation of platinum particles on titania observed under reducing conditions is lost once the system is exposed to a redox-reactive environment containing oxygen and hydrogen at a total pressure of ~1 bar. Destabilization of the metal–oxide interface and redox-mediated reconstructions of titania lead to particle dynamics and directed particle migration that depend on nanoparticle orientation. A static encapsulated SMSI state was reestablished when switching back to purely oxidizing conditions. This work highlights the difference between reactive and nonreactive states and demonstrates that manifestations of the metal-support interaction strongly depend on the chemical environment.diqiukexueEarth SciencePersistent influence of precession on northern ice sheet variability since the early Pleistocenezaogengxinshiyilaisuichaduibeibubinggaibianhuadechixuyingxiang▲ zuozhe：STEPHEN BARKER, AIDAN STARR, JEROEN VAN DER LUBBE et al.▲ lianjie：https://www.science.org/doi/10.1126/science.abm4033▲ zhaiyao：100wannianqian，quanqiubingliangdebianhuazhuyaoshiqingjiaodebianhua；raner，suichachanshenghezhongzuoyongdewentirengranmeiyoujiejue。tongguoguoqu170wanniandebeidaxiyangbingpiaoliujilu，womenfaxiantedingbingchuanzhouqi（fanyingliaobinggaidekuozhang）zhongbingpiaoliuqishitongchangchixuzaiqingjiaojiaoshaoerdaguimobingxiaorongshijianduyusuichadezuixiaozhixiangguan。ciwai，womendeyanjiujieguobiaoming，zaizhong-wangengxinshishiqi，yousuichaqudongdedaguimoxiaorongshijianyubingxiaoqizhijianpubiancunzaiguanlian。zaizengjiafashengqian，qingjiaobenshenjiuzuyijieshuyicibingqixunhuan，zaiyue100wannianyihou，suizhuobeibanqiubingyuandenanyan，qingjiaoshiquliaoduibingchuanxiaotuidezhudaozuoyong。▲ Abstract：Prior to ~1 million years ago (Ma), variations in global ice volume were dominated by changes in obliquity; however, the role of precession remains unresolved. Using a record of North Atlantic ice rafting spanning the past 1.7 million years, we find that the onset of ice rafting within a given glacial cycle (reflecting ice sheet expansion) consistently occurred during times of decreasing obliquity whereas mass ice wasting (ablation) events were consistently tied to minima in precession. Furthermore, our results suggest that the ubiquitous association between precession-driven mass wasting events and glacial termination is a distinct feature of the mid to late Pleistocene. Before then (increasing), obliquity alone was sufficient to end a glacial cycle, before losing its dominant grip on deglaciation with the southward extension of Northern Hemisphere ice sheets since ~1 Ma.Where rivers jump courseheliu“tiaoyue”dedifang▲ zuozhe：SAM BROOKE, AUSTIN J.

The controls on avulsion locations are poorly understood as a result of sparse data on such features. We analyzed nearly 50 years of satellite imagery and documented 113 avulsions across the globe that indicate three distinct controls on avulsion location. Avulsions on fans coincide with valley-confinement change, whereas avulsions on deltas are primarily clustered within the backwater zone, indicating a control by spatial flow deceleration or acceleration during floods. However, 38% of avulsions on deltas occurred upstream of backwater effects. These events occurred in steep, sediment-rich rivers in tropical and desert environments. Our results indicate that avulsion location on deltas is set by the upstream extent of flood-driven erosion, which is typically limited to the backwater zone but can extend far upstream in steep, sediment-laden rivers. Our findings elucidate how avulsion hazards might respond to land use and climate change.Models predict planned phosphorus load reduction will make Lake Erie more toxicmoxingyucejihuazhongdelinfuhejianshaojiangshiyilihudeduxinggengda▲ zuozhe：FERDI L.

We performed a large-scale meta-analysis including 103 papers and used it to develop a mechanistic, agent-based model of Microcystis growth and microcystin production. Simulations for Lake Erie suggest that the observed toxigenic-to-nontoxigenic strain succession during the 2014 Toledo drinking water crisis was controlled by different cellular oxidative stress mitigation strategies (protection by microcystin versus degradation by enzymes) and the different susceptibility of those mechanisms to nitrogen limitation. This model, as well as a simpler empirical one, predicts that the planned phosphorus load reduction will lower biomass but make nitrogen and light more available, which will increase toxin production, favor toxigenic cells, and increase toxin concentrations.yizichangzidegaibianwenti，yinfayuanzhushumideshengtao。

与82岁老人一起，我自然过上了老年生活。仅仅五个月，我发现自己有了很大变化，先是思想上越来越懈怠，再是行动上越来越迟缓，三是心理上越来越空虚，很向往远处的风景，可那些风景只是风景了。从保额和赔付支出来看，2022年财险公司保额同比增长14.71%，与2021年45.53%的保额增幅相比明显放缓；财险公司赔款支出同比增长2.60%，与2021年13.55%的赔款增速相比也明显放缓。对此，谢远涛分析认为，2021年保额大幅增长抬高了基数，2022年尽管保额增速有所下滑但也高于保费增速，体现了行业进一步回归保障功能。而赔款支出仅出现小幅增长，主要是因为去年车辆出行明显减少，车险出险率和赔付率明显下降。我的狗丈夫最新章节冲我的狗丈夫(午夜人屠)小说全文...
