一系列不同寻常的失误、不幸和疏忽导致核裂变的发现一直推迟到二战前夕,或许因此改变了历史的进程。与其他的物理发现不同,裂变的发现完全是出人意料的。当哈恩和斯特拉斯曼发现铀元素被中子轰击后会导致钡元素的出现时,他们是如此震惊,以至于在宣布这一发现的论文中写道:“我们还没有准备好迈出如此巨大的一步,它与所有已知的核物理实验相背离”。哈恩和斯特拉斯曼的发现刚好发生在二战爆发前9个月,一个历史命运的关键时刻。六年后,恰恰是这一来自纳粹德国的发现直接导
The discovery of a series of unusual mistakes, misfortunes and negligence that led to nuclear fission has been postponed until the eve of World War II, perhaps changing the course of history. Unlike other physical findings, the discovery of fission is completely unexpected. When Hahn and Strasman found that the uranium element was bombarded with neutrons, which led to the appearance of barium, they were so shocked that in a paper announcing the discovery, “We are not ready yet.” At such a huge step, it departs from all known nuclear physics experiments. " Hahn and Strasmman’s findings happened just nine months before the outbreak of World War II, a crucial moment of historic destiny. Six years later, it is precisely this direct result of the discovery of Nazi Germany
