軍事大國的美國是如何運輸核武器的？ (How the US Transports Its Nuclear Weapons)
- You see, the delicious plutonium center of every nuclear warhead has an expiration date—a point past which it won't detonate reliably—and the problem is… we don't really know when that expiration date is.
你看，每個核彈頭的美味鈽中心都有一個失效日期——超過這個時間它就不會可靠地引爆——而問題是……我們真的不知道這個失效日期是什麼時候。
- So instead of rolling the dice on World War 3, the Department of Energy has started the process of recycling and replacing the plutonium in each of these warheads,
因此，能源部沒有在第三次世界大戰上擲骰子，而是開始回收和更換每個彈頭中的鈽，

芭比與奧本海默的科學大揭祕！⚛️ (The Science of Barbie & Oppenheimer Explained)
- To make this happen, Oppenheimer's bomb used TNT to compress plutonium so densely that it made its atoms bump into each other and break down, resulting in an incredibly powerful explosion.
Bob，我喜歡你對知識的渴望，但是
- To make this happen, Oppenheimer's bomb used TNT to compress plutonium so densely that it made its atoms bump into each other and break down, resulting in an incredibly powerful explosion.
為了達成這個目標，Oppenheimer 的炸彈使用了 TNT 來壓縮鈽，使其密度極高，原子互相碰撞並分解，產生了極其強大的爆炸。
