So far it was a lab accident under investigation: The exact details of Tiansi Xin’s death are still under investigation, but some witnesses and authorities have provided their accounts of what happened. According to them, Tiansi was working in his laboratory at the MIT Chemistry Building, around 2 p.m. on November 16, 2023. He was performing an experiment involving the reaction of a phosphorus compound with a metal hydride, under high pressure and temperature. He was using a sealed glass vessel, equipped with a pressure gauge and a safety valve. As he was monitoring the reaction, something went wrong, and the vessel exploded, releasing a large amount of gas and debris. The explosion shattered the windows and the walls of the laboratory, and triggered the fire alarm and the sprinkler system. Tiansi was hit by the blast, and suffered severe injuries and burns. He was found unconscious and bleeding by his colleagues, who called 911 and tried to help him. He was taken to the Massachusetts General Hospital, where he was pronounced dead. https://www.emlaksatan.com/en/tiansi-xin-death-cummins-mit-chemistry-department-student-has-suicide/

高温，高压，金属氢化物，有机磷，玻璃容器爆炸。
金属有机化学实验真危险。
Xin同学在实验室爆炸事故之前一天的Seminar：

我们知道有机合成中含氮杂环化合物非常重要，而磷与氮是同族，有机磷研究对于制药、杀虫剂、电池还有生态环境都意义重大。
这种事要是发生在中国学校早就被骂惨了。MIT 官方为什么不说，隐瞒事实？
多不容易啊，北大，mit.

这和中国有什么关系？戏多！
死的是个中国人，跟中国没关系？
和遇事就比较中美无关。就像你抱怨一下美国，人家就问候你家的铁链女同理，戏多！
对啊，所以到底是意外还是自杀？有报道说，他那种级别的科学家不可能导致这么低级的错误，所以应该是自杀。问题是谁没事拿实验自杀？还搞那么惨烈？
就目前的消息似乎意外的可能性比较大了。都没搞清原因就一推学霸抑郁自杀的推测，怎么感觉很多对学霸有深深的恶意呢？还是普通人想在个别学霸不幸的个例中寻求安慰？放心吧，大部分学霸比普通人的人生精彩和富有。
再苦再累都抵不过喜欢。没有对照组的实验，你欣慰个毛？人家女儿之前选化学也许单纯喜欢和擅长。指导自己的小孩就是有病的家长，还把手伸到别人家的小孩，真是有蠢又萌！
蠢的是你自己！ 人女儿全面发展又喜欢化学又喜欢计算机， 父母向我咨询意见，现在女儿纽约藤校读计算机， 全家高兴， 你把手伸到我贴子下真是找骂
还有对教授，对中国教授……
如果老板愿意放人毕业的话应该没啥吧，毕竟没什么国内常见的“指标”
我附近一学校最近三年两个年轻化学博士癌症去世，不知道是不是和化学试剂有关。
唉，父母哭死了，多阳光帅气的小伙子
北大毕业，26岁五年博士，一篇行业高水平文章，很出色啊，我们这博士毕业实验报告式的文章有的是。可能你比他出色，但是毕竟是少数。
如果是事故，学校说是自杀，这就像用🔪杀家长一样
这里just had的意思是他们刚发了一个to paper 不是说只有一个paper
赞层主！我就是在家长的建议下选了计算机没选化学。我爸妈的理由是（1）化学有毒，（2）化学危险，尤其是我比较粗心。现在看来他们太明智了。 认为化学有毒也不是凭空想象。原来我家在航天部三院，有个101站是搞化学的，旁边门诊部设定的转氨酶指标都和普通医院不一样，因为101站的人普遍转氨酶高。这是三十多年前的事儿。 也不是说学计算机就一定好，后来我也转专业了。但是学化学确实有风险。
很有可能。参见中山大学最近的事
没有任何其他creditable的网站有说这个，mit校友都没看到实验室爆炸新闻，看来这个是假新闻的可能性极大。
