被这个问题的脑洞震惊了！

If I'm cooking, and I cut a tomato, is there a chance that the knife would split an atom while it slices into the tomato to cause a nuclear explosion?

菜刀切到西红柿中的原子会引发核爆炸吗？

Rob Aleksick:

No. Because:
不会。因为：

1. The sharpest knife in your kitchen is still way too dull to even approach the width of an atom; and
   厨房中的刀具即使是最锋利的那种，它的厚度相对于原子而言依旧是太大了；并且

2. Even if you had some super-knife that was one atom thick (thin?) at the edge (like an Obsidian Scalpel), it wouldn't "split" an atom--it would just push it aside; and
   即使你有一把超级菜刀它的刀口有像原子一样厚（薄？）（就像 Obsidian Scalpel一样），它也不会“切开”原子，而是把原子推到一旁；并且

3. Even if your super-knife were able to somehow split an atom, nothing would happen because tomatoes are basically made of carbon, oxygen, and hydrogen, and splitting those light elements results in no energy release (as opposed to splitting a heavy element like uranium); and
   即使你的超级菜刀能够切开原子，这也不会导致任何事情的发生，因为西红柿主要是由炭、氧、氢组成，切开这些轻元素不会导致能量的释放（反之则是切开例如铀之类的重元素）；并且

4. Even if splitting a carbon atom released as much energy as uranium, it's still just one atom--a nuclear explosion is a chain reaction of unimaginably many atoms splitting, each releasing a little energy, and using a bit of that energy to split another atom. It adds up when you're doing it 10²⁴or10²⁵ times like in a bomb, but one atom? Not much to worry about.
   即使你切开一个炭原子能够释放像铀一样多的能量，这也只是一个原子而已，核爆炸需要数量多到难以想象的原子被切开来产生链式反应，每个原子都释放一点能量，然后使用这些能量的一部分来继续切开其他原子。加起来在原子弹中大约有10²⁴次或者10²⁵次，如果只是一个原子，那就不用担心了。

I'd be much more worried about slicing your thumb with that super-sharp knife of yours:)
相比之下，我更担心你被那把超级菜刀切到你的手指:)
