近日,东南大学博士生导师陈洪兵教授在小红书上说:自从博士扩招,博士由考试入学改为考核入学后,博士生源质量明显下降,博士们根本不读书,水平比硕士还差。所以近年来他都是劝退想读他的博士的考生们,先想清楚再读博,宁缺毋滥。混个博士学位一点用都没有,纯粹浪费教育资源!

As far as WIRED can tell, no one has ever died because a piece of space station hit them. Some pieces of Skylab did fall on a remote part of Western Australia, and Jimmy Carter formally apologized, but no one was hurt. The odds of a piece hitting a populated area are low. Most of the world is ocean, and most land is uninhabited. In 2024, a piece of space trash that was ejected from the ISS survived atmospheric burn-up, fell through the sky, and crashed through the roof of a home belonging to a very real, and rightfully perturbed, Florida man. He tweeted about it and then sued NASA, but he wasn’t injured.
