20世纪的战争与和平 

材料  早在1910年，俄国科学家就发现了放射现象。1941年4月，苏联驻纽约的情报机构向国内报告，西方最著名的物理学家正在谈论铀具有的巨大军事意义。其后苏联著名物理学家库尔恰托夫被任命为发展核计划的学术负责人。1943年4月，来自全苏的著名专家开始了研制工作。1945年8月，苏联国防委员会通过决议，着手研制原子武器，以打破美国的垄断。斯大林对库尔恰托夫说：“请说出您需要的一切帮助，您不会遭到拒绝的。”苏联部长会议成立了直属部长会议的管理总局负责研制工作。参加这项工作的人员达数十万之多。一位参与者写道：“我们能够团结一致，首先是给我们提供了相当优越的科学工作条件。其次，是内心的感觉，即击败法西斯德国后，我们同最强大敌人的对抗仍没有结束。”1949年8月，苏联第一枚原子弹试爆成功。
