Meitner and her colleagues learned that splitting atoms releases large amounts of energy, and she was the first person to describe and name the process of nuclear fission in a scientific paper.

迈特纳和她的同事们发现，原子分裂会释放大量能量，而她是第一个在科学论文中描述并命名核裂变过程的。

It's where the structure and presentation give meaning to and become meaningful through that endless loop of fission and fusion, letting us experience all at once: past, present and future.

在这，结构和呈现通过裂变和融合的无尽循环赋予意义并变得有意义，让我们同时体验到所有的东西：过去，现在和未来。

Officials at Howe have said the PPR is based on another plasma-based technology known as pulsed fission fusion.

The project to design a small nuclear fission system is called Kilopower.

设计小型核裂变系统的项目称 Kilopower。

He did not know, he did not even suspect, that under certain conditions of atmospheric potential and of ground magnetic stress his perfectly designed lightning rod system would become a super-powerful magnet for flying vortices of atomic disintegration.

他并不知道， 甚至未曾怀疑过，在特定的气压和地磁应力条件下， 他精心设计的避雷系统会变成吸引原子裂变涡流的超级强力磁体。

Hitler had become very interested in nuclear fission's potential and there was a real fear in the United States and in Europe that Nazi Germany would develop a weapon that harnessed the immense power of nuclear fission.

希特勒对核裂变的潜力产生了极大的兴趣，美国和欧洲真的担心纳粹德国会研发出一种利用核裂变巨大威力的武器。

Martin Darpa spacecraft will carry a small nuclear reactor Inside Iranian atoms will split to generate tremendous heat That heat will be absorbed by liquid hydrogen sucked from a tank on board.

马丁国防高级研究计划局的航天器将携带一个小型核反应堆，伊朗原子将在其中裂变产生巨大的热量，这些热量将被从机上储罐中抽取的液氢吸收。

We all know the tragedy that arises from splitting of the atom, and yet so much, I mean, The atom itself does not care for what purpose it is being split, so.

我们都知道原子裂变带来的悲剧， 然而，我的意思是，原子本身并不在乎它何被分裂， 所以。

The latter were enormous undertakings given the technology available to the Manhattan Project, as it was extremely costly and time consuming to enrich these to become fissile substances in the mid-1940s.

后者是巨大的工程任务，鉴于曼哈顿计划可用的技术，在20世纪40年代中期 enrichment 这些物质成裂变物质的成本极高且耗时极长。 注：原文中的 " enrich" 通常指的是铀的同位素浓缩过程，在此上下文中可以翻译“提纯”或“富集”，但了保持与核技术相关的专业术语的一致性，这保留了“enrichment”。如果需要进一步简化，可以将其翻译“提纯”。

The same year, Albert  Einstein presented the military potential of nuclear fission to Franklin Roosevelt, and by  February 1940, the US government had funded the project with an initial $6,000.

同年，阿尔伯特·爱因斯坦向富兰克林·罗斯福介绍了核裂变的军事潜力，到 1940 年 2 月，美国政府该项目提供了最初的 6,000 美元资金。

And even if you stick with a simpler bomb that only uses fission you'd need to keep it tiny and keep those reactions going instead of just fizzling out.

而且即使你选择只使用裂变反应的简单炸弹，你也需要让它保持小巧，并持续进行这些反应，而不是很快就失效。

It was probably a year before Iran would have enough fissile material, enriched uranium at a high enough percentage to be able to fashion one nuclear weapon.

伊朗可能需要一年的时间才能积累足够的裂变材料， 即 enrichment 到足够高的百分比的铀， 从而能够制造一枚核武器。 注：原文中的" fissile material" 指的是“裂变材料”，而" enriched uranium" 通常翻译“ enrichment 铀” 或“高浓铀” 。 了保持与参考术语的一致性， 并考虑到上下文， 这使用了“enrichment 铀” 的表述方式。 不过，“enrichment” 在这应理解动词形式的过去分词， 意指“已经 enrichment（提纯）过的铀” 。 在正式文本中， 可以将其直接翻译“高浓铀” 。
