Man they could have forced countless generations to fight genocidal wars without the monotheistic religious pretext or impetus if this has really happened.
The energy from nuclear reactions can be astonishingly large (compared to, say, chemical reactions).
But atoms are really, really, really small.
people with good vision can probably see a single gold atom, I seem to remember that one useless fact about the smallest things we can see
Not even close, a gold atom is about 140 pm, while the diffraction limit for optical microscopes is around 200 nm, so 1000 Times bigger. And this does not mean that you could see a 200 nm object, only that you can differentiate 2 objects that are at least 200 nm apart. https://en.wikipedia.org/wiki/Diffraction-limited_system So no it is not possible to see atoms with visible light photons.
Nope. Atoms are WAY too small to see, even with the most powerful optical microscopes.
You may be thinking of a human egg cell, which can be seen with the naked eye.
I remember growing up as a kid, doing my time in Sunday School, and getting this story pitched as “Wise King Solomon ferret’s out the truth of maternity by determining which claimant truly cares about the life of the child”.
It’s kinda crazy how the story has permuted into “Two women fight over a thing and both agree splitting it in half is the fair solution.”
What I like about the story is that true motherhood isn’t about biology or DNA but about caring. And I get why even people who care about the well-being of a child wouldn’t care about the well-being of an atom
Real talk: Would literally cutting a single atom in half unleash the force of an atomic bomb? Would it even be a noticeable reaction to the unassisted human eye?
I’ve seen some science show stuff at particle accelerators where a dude points to some device giving off sparks and is like “these sparks are actually anti-matter explosions.” So I wonder if a single atom of regular matter would even be a spark.
I found a similar discussion on Reddit and liked this comment because it was easy to understand:
The energy released in the fission (splitting) of ONE atom of U-235 is enough to make a single grain of sand visibly move.
It’s apparently a quote from the book The Making of the Atomic Bomb by Richard Rhodes.
There are carbon atoms splitting (decaying) inside of you right now. This is why carbon dating works. Do you notice them?
Yeah, unless the atom in question is neutronium, you won’t notice and if it is neutronium, you have all kinds of issues even without splitting it.
This reminds me of people freaking out over particle accelerators. Will it create a black hole???
Only they don’t know that the Earth is regularly bombarded with high energy particles from space. The reason we need particle accelerators is so that we can accelerate the desired types of particles to the desired speed, and aim them at the desired place.
Most people have no idea just how little they actually know about the world around them.
Hell, most of what the average person “knows” is just made up assumptions they had about things they knew little to nothing about and subsequently internalized those assumptions without actually researching if they were correct.
Humans are hella prone to trapping ourselves in fallacious thought without even knowing we do it. It’s just how our brains have evolved to work through inductive reasoning.
There are carbon atoms splitting (decaying) inside of you right now… Do you notice them?
Silly talk: Idk… I sometimes get this weird, tingling feeling through my whole body. You think it might be carbon decay?
Not unless you feel it all the time (and even if you do, the energy released is not enough to activate nerve endings).
Only a tiny part of the atom is converted to energy in fission. An antimatter annihilation is 100%
Even then a hydrogen+anti hydrogen releases 1.86 x 10⁻¹⁰ Joules.
You need about 4 joules to heat 1g of water by 1C
and one annihilation is 0.000000000186J
Bananas emit antimatter.
So what happens when you split a banana split?
You make a friend.
it rather depends on the atom and how you go about doing it- and also, what the atom is surrounded by. if it were split in such a way that neutrons were released into other neutrons, generating a cascade reaction… then… yes. That’s kinda how a nuke works.
But in general? probably not.
It worked in the movie Young Einstein and I trust movies, not really I just wanted to make an amusing but related comment about a lesser well than known movie of my youth. Of course since it’s a comic seems semi relevant, it was a part of the movie trailer heh unless my memory is worse than I hope but I don’t want to delve there.
I think the most concerning thing would be the radiation that it would give off. Aside from that, I’m not really sure it there would be more than a possible spark as you mentioned, though it may also depend on the size of the atom.
As I’ve learned more, the energy from a single atom is not much. They split nitrogen long before uranium but it didn’t really matter. You need the chain reaction of uranium.
From Gemini:
The energy released from a single uranium atom splitting is an infinitesimally tiny fraction of what’s needed to even warm a mug of water. You would need the simultaneous fission of approximately 1.96 quadrillion (1,960,000,000,000,000) uranium atoms to heat a single mug of water.
*JFC what’s up with the downvotes? Because I used Gemini?
I’m not downvoting you, but I think a lot of people, including me, would read “from Gemini” (or any AI) as “you can’t trust this information”.
ChatGPT will straight up hallucinate numbers (or any information). Gemini is much more accurate. Haven’t tried others.
Thank God there was an AI here to tell us something we could just look up.
I was interested in whether this was accurate. I got a similar answer, but I know almost nothing about nuclear fission and math is not my strong suit. Here it is anyway:
The heat capacity of water is fairly linear. At normal atmospheric pressure, it’s 4,200J/kg°C, which means a 300ml mug of water would take 1,260 joules to raise by 1°C and thus 75,600 joules to raise by 60°C.
Fission of a single atomic nucleus of U-235 releases an average of 3.2e-11 joules (0.000000000032). To release 75,600 joules would presumably take fission of 2.3625e+15 atoms (2,362,500,000,000,000 – two quadrillion three hundred sixty-two trillion five hundred billion).
You uh definitely at least took a heat transfer class in college or you wouldn’t know what to do with all this stuff. Hell, I took one 10 years ago, and I barely know what to do with this information anymore. Kudos to you for doing the napkin math
Nah, just read into it a little and then forgot it afterwards! The first link – the old Reddit thread – was quite helpful.
Considering it was 250 ml by 60 C, looks bang on.
You would need the simultaneous fission of approximately 1.96 quadrillion (1,960,000,000,000,000) uranium atoms to heat a single mug of water.
heat by how much? AI as useful as ever.

I just cut that bit out. 20 C to 80 C.
Even MY anium???
No, I amanium!
Isn’t that common knowledge? I don’t think that anyone seriously believes that splitting a single atom causes an explosion.
I mean I’m not saying that you’re an expert, but my us highschool education regarding nuclear fission was pretty handwavy, and won’t come up again in most careers
I’d wager loads of people with no scientific knowledge do.
I’d wager they don’t even know what you mean by “splitting an atom” and wouldn’t give a rat’s ass whether it released any energy.
