If I'm to believe that second person didn't misspeak, they had "mental breakdowns" with an "s", so multiple breakdowns, over the thought that their eating lettuce could cause a nuclear apocalypse.

They must really like lettuce. If I had a mental breakdown over the fear that my eating a specific food would cause untold human death and suffering, including my own, I would likely not eat that food again until I could convince myself it was safe.

    Maybe after the first few mental breakdowns, they could have maybe just gone on the internet may be kind of like, I don't know, learned more. So they were saying they were just so sure that they could accidentally split atoms and they didn't question why there weren't nuclear explosions going off at every restaurant hundreds of thousands of times per day.

    I guess you did not grow up with parents that forced you to clean up your plate before leaving the dinner table

    Sometimes all kids need is a scientifically literate adult to explain precisely why their fear isn't possible.

    Reminds me of a profoundly stupid movie I saw as a child called Young Einstein starring Yahoo Serious and no that’s not aphasia talking. He takes an atom out to the shed and splits it with a chisel. An explosion ensues, complete with charred face and smoking hair standing on end.

    I loved this story, thank you for sharing.

    I think the people who sleep well at night are the ones that don't care how anything works. Sometimes it's ignorance, but often it's just burnout, and worse sometimes it's a complete lack of empathy for anything that isn't themselves.

    Atoms lettuce break the iceberg.

    A single atom wouldn't even be worse than, like, a pop rock anyway. You need a whole mess of them motherfuckers to make a big boom.

    If I accidentally bite an atom and the tiny shards shatters nearby atoms, wouldn't that just make more? Like sort of.. a chain reaction ?

    Maybe I just have to gobble up all my salad before all the booms blow my jaws and neighbours away.

    It would not make a chain reaction because the nuclei of typical atoms are unlikely to split when irradiated (that is to say, hit by the pieces of the original atom that split) and will more likely ionize (have an electron knocked off) or transmute (turn into a different element by changing the number of protons).

    In nuclear weapons or reactors the uranium must be "enriched" because regular uranium atoms are too stable to sustain a fission reaction. We must have a high amount of rare uranium-235 (the easily splittable isotope) compared to U-238 (the more common stabler isotope) which is why uranium needs to be enriched. Most of the atoms in your salad are stable isotopes, so there will likely not be any cascading fission reactions even if your teeth were somehow able to trigger one (or even 1000) every single time you took a bite.

    When I learned about germs, how they're everywhere and too small to see, I thought I must be squishing them every time I touch anything. So I went around the entire house touching every surface, especially the windows, because nobody ever touched those.

    Yep was super paranoid and anxious over misunderstandings now just super paranoid and anxious over worst case unlikely scenarios.

    I remember being told "Atoms are always moving", so I would cut reeeeaaaalllllyyyy fucking slow for a bit thinking that the atoms would "move out of the way."

    I also just read my husband this meme and he was like "Oh yeah. I remember thinking I was risking my area for arts and crafts."

    When I was a kid, I was playing one day outside and then later I realized there is an ant nest nearby and I saw that I killed some ants by walking near it.
    After that, I didn't want to kill any more bugs etc, so whenever I was walking on grass, I would always check the grass before me to see if there are any bugs in it, and only then I would make a step.

    Yeah, it was very slow and inefficient, but it wasn't that bad because I was actively avoiding grass and this whole experiment didn't last very long either, maybe a couple of months.

    Then I went back to stepping on the bugs.

    If you did manage to do this by random chance would you even notice? A single atom is pretty small. If you somehow split a random carbon atom in lettuce wouldn't you get less than a Joule as long as it doesn't somehow chain?

    This is just what I've heard a long time ago so don't quote me lol. But no, splitting a single atom shouldn't do anything of note. I believe it's the same general reason that a nuke doesn't set the entire atmosphere on fire - you need a lot of energy to split atoms. That's why nukes need enriched materials.

    I also believe that even a nuclear explosion won't be triggered by a single split atom in a bomb. For example, the Manhattan Project bomb was triggered by shaped explosives that surrounded the nuclear core. The blast of the charges "compressed" the nuclear material to the point it reached a critical mass that allowed a runaway fission reaction.

    Yeah it would be small to the point of not being perceptible. A single atom has an insane amount of energy for its size, but its still not enough to move a grain of sand any amount that would be perceptible to the naked eye

    When I was in kindergarten they showed us a cartoon with anthropomorphic teeth to try to encourage dental hygiene and those teeth scared me so much that I refused to brush my teeth for years and I ended up getting gum disease because of it.

    Its not possible to do by any metric. And besides, a chain reaction is needed. A single atom turned into pure kinetic energy wouldn't be noticeable at all.

    Just be glad no one showed you crunching life savers in the dark.

    I guess there are two kinds of people because when I learned that splitting atoms causes a nuclear explosion, I got a craft knife and some sand from the garden and went to town on them trying to slice some atoms just right 👌
