1938年底,正值第二次世界大战爆发前夕,从纳粹德国传来一条振惊世界科技界的消息。“铀原子裂变时会放出巨能。”翌年初,其它一些国家的物理学家如弗里德里克·约里奥一居里等人也得出相同结论:铀原子裂变时可引起链式反应,产生惊人的爆炸。这年4月英国军事研究领导人铁札德向政府建议,要想法阻挠德国人把世界库存的铀集中到他们手中,并预言铀矿石一旦落入纳粹手中,将会带来世界性灾难。但这种努力未达所期成效。第二年5月,比利时连同1200吨铀矿石落入纳粹之手。已经相信铀的战略价值的比利时卡坦加铀矿的经理艾德加·辛日将该矿最后一年开采出来的铀矿石偷偷运到了纽约,成了日后曼哈顿计划的原料。这批矿石到了美国后起先却未能引起足够的重视。科学家里奥·斯宙
At the end of 1938, just as the eve of the outbreak of World War II, news of a world-wide technological stir was shocked from Nazi Germany. "At the beginning of next year, physicists in other countries, such as Frederick Joel of Curie and others, reached the same conclusion: when uranium atom fission can cause chain Reaction, resulting in a surprising explosion. In April of this year, Tiezhad, the leader of the British military research, suggested to the government that it would be a worldwide catastrophe if he thought of blocking the Germans from concentrating the world’s stored uranium in their hands and predicting that the uranium ore will fall into the hands of the Nazis. However, such efforts have not reached the expected results. In May the following year, Belgium, together with 1,200 tons of uranium ore, fell into the hands of the Nazis. Edgar Xinri, the manager of Katanga uranium in Belgium, who has believed in the strategic value of uranium, secretly transported the uranium ore mined in the last year of the mine to New York as raw material for the Manhattan plan for the future. After arriving in the United States, the ore failed to attract sufficient attention. Scientist Rio Cosmos
