Let me at 'em!!

Knives are also made of atoms
- Sure? How many? Because I have some atoms at home and need a new knife
  
  At least 50
- Not this knife
- Call that a knife?
- Atomception
- Some are smaller than others
- They could be made of degenerate matter.

Don't eat fissile cucumbers.

One of these nerds is not like the others,
One of these geeks just doesn't belong,
Can you tell which nerd is not like the others
By the time I finish my song?
- I don't like Tyson because I feel he preaches an inaccurate version of the scientific philosophy. So many times I hear him saying things along the lines of absolute certainty, because it's SCIENCE.
  Where, we of the true faith, preach: the evidence indicates that this is the most likely to be true, or at least, this model makes predictions about the world more reliably than any other we currently have.
  Amen.
- Tyson? Why not cause he's an asshole? Are you aware that both Einstein and Hawkings were also assholes?
  
  While Einstein and Hawking (no s) were giants of their field, published papers that turned all other accepted science on its head, and have basic physical phenomenon of the Universe named after them, they were surprisingly limited in their knowledge of other fields. Whereas NdT will expound on absolutely any topic with the complete certainty that he is a fucking expert, even if he only just now inferred the existence of the thing from the question he is presently being asked. He is a Mycroftian megabrain of galactic proportions, a fact he appreciates better than anyone else.
  
  But they weren't pretentious know-it-alls on TV and YT

We're gonna need a community for comedy homicide for this. That last panel ruins it.
- !comedyhomicide@lemmy.world exists but has no posts, consider cross posting

Then he went on to make lemonade with strawberries and heavy water. Deuterium, you get me? Strawberry fusion lemonade.
- No I don’t get it. But I would like to. Is this one of those scenarios where three physicists walk into a bar, each one tells a joke but none of it are funny so no one gets it?
  
  The moment I wrote it, I was hearing it in the voice of Benny Safdie in his first scene as weirdo Edward Teller, in "Oppenheimer".
- Is that what killed that girl at Panera a while back?

And that's how we got bubbles in beer.
- I'm glad someone else remembers that movie.
  
  God, I saw it in the theater. That theater was almost completely empty.
  
  *chop "damn." *chop "damn." *cho -BOOM

That's gotta be the sharpest knife in existence having a diameter of half an atom...
- Doesn't have to be sharp. It could be extremely fast.

That's a 4D knife.

When I was a kid, I was legitimately afraid of this

reminds me of yahoo serious splitting a beer atom with a chisel in his shed. young einstein, what a fun movie

And that's why you don't see cooking mouse no more.

Sad to not see more comments about The Subtle Knife. This is a great meme for that concept!

Let me atom *

Hawking, my guy, why have you forsaken us? 🥺 I believed in you

That’s easy to explain, having cut a lot of cucumbers in my life. Since the actual nucleus of an atom is much smaller than the atom including its electrons itself, the probability of hitting the protons or neutrons is so small, that I’d need to live for a few thousand years and cut 1 cucumber per second nonstop, before this scenario happens even once. It is not impossible, just very improbable.
- (assuming your post isn't a joke) it is impossible to cause a nuclear reaction by cutting cucumbers.
  the biggest innacuracy in this comic is that as the panel zooms in on the cucumber atoms, the knife looks exactly the same. if it was realistic it would just be a bunch of metal atoms pushing aside a bunch of cucumber atoms, not a sharp knife slicing through individual atoms.
  
  Bro, you should sharpen your knives.
  
  Maybe it's not zooming in. Maybe the atoms of the cucumber are getting bigger! 😏
  
  Well… that, and one nucleus splitting in half wouldn‘t start a chain reaction in a cucumber, and therefore not release a macroscopically noticeable amount of energy.
  
  The Subtle Knife is definitely so sharp that it cuts through dimensions, so I think it would cut atoms.
  So really that just means it's not inaccurate, it's just a very specific, fictional knife!
- Fission doesn't happen because we cut atoms in half. Fission happens because we blast enriched uranium with neutrons, the uranium absorbs a neutron, gets too heavy, and falls apart.
  I mean think about it. Atoms are surrounded by a negatively charged electron cloud. Pushing 2 atoms together would be (sorta) like trying to push the like poles of two magnets together.
  
  That’s just one way to do it.
  
  Sure, but you can also rip off electrons from atoms by rubbing them or bending a piece of wire. The energy needed to trigger fission in uranium is less than a picojoule, it just needs to be focused enough to knock away the part of the atom, which is why neutrons are the most common way.
  Here is a chart with the rate of fusion for two hydrogen atoms at various temperatures.
  https://en.m.wikipedia.org/wiki/Nuclear_fusion#/media/File%3AFusion_rxnrate.svg
  This chart bottoms out at a few million degrees, since the probability is extremely low.
- I know very little about physics and I'm pretty sure you could cut cucumbers with a knife until the end of time and you'll never trigger a nuclear explosion.
- It’s also why cats are afraid of cucumbers.
- Actually, it's because cucumbers are so cool (c.f. cool as a cucumber) that they're in a ground state. It's actually endothermic to split their atoms so you don't get a chain reaction.
  Cutting hot vegetables, habernaros for example, is much more risky and adequate precautions should always be taken to avoid radioactivity contaminating sensitive regions of the body.
  
  I thought the only option with cucumbers is to keep mashing them together until fusion, no?
- Ok if it is theoretically possible to cut atoms by using metal knives then why didn't ever a fission happen? I mean if you combine all knife cutting in the whole world since knives exist, the probability should be pretty high.
  
  Well, it probably happened an infinite amount of times already. But the resulting cucumber-detonation just triggers a new Big Bang. We’re on the whatever-millionth reset now. Should end any day now. STOP CUTTING CUCUMBERS, SHEEPLE!!
  
  I mean, this happened once: https://www.iaea.org/newscenter/news/meet-oklo-the-earths-two-billion-year-old-only-known-natural-nuclear-reactor
- You're assuming the blade would be thinner than the nucleus, at the very least.
- But what would you do with the sliced cucumbers of millenia?
  
  Dunno. I guess growing them fast enough would also be a problem.
- The electromagnetic force from the atoms' respective electron cloud probably help prevent atom from getting close to each other. And the strong nuclear force also help prevent atom from splitting.
  
  You mean I’m just not cutting strong enough?
- Someone let Einstein loose, we must admit that violence is on occasion the only recourse.
- Okay, now explain bananas.
  
  Well, that’s why we generally eat bananas without cutting. As everyone knows, bananas are slightly radioactive. This increases the danger when cutting them exponentially, so don’t do that.
- Not with that attitude.
- You're doing it wrong. The mouse just diced a cucumber really, really l, small.

knife shrinks
