Shi, a famous patriotic scientist. He was a tenured professor at Princeton University before returning to China. According to a friend of mine who is a graduate student in Princeton, the academic level of history is medium in Princeton. Don't underestimate the mid-stream, such figures can almost sweep the Chinese Academy of Sciences when they return to China. Rao Yi was a returned scientist at the same time as Shi. He also got a tenured professorship at Washington University in St Louis, and then quit his job and returned to his motherland. He returned to China a year earlier than Shi. Rao Yi's academic achievements have not won the Nobel Prize, and the number of papers published in Nature is slightly lower than that of Shi et al. This may be because he pays more attention to teaching, and Shi is a typical "laboratory scientist". Shi sometimes makes speeches with mystical tendencies. Because there are mysterious elements in it, someone deliberately added more mysterious rubbish to his speech, saying that it was published by Shi, which made Shi quickly come forward to refute the rumor. But Shi's speech does have some mysterious tendencies. Rao Yi doesn't have these things. Therefore, Rao Yi's scientific literacy is indeed higher than history.
