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?

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

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

Knives are also made of atoms

[–] [email protected] 9 points 3 weeks ago

Call that a knife?

[–] [email protected] 2 points 3 weeks ago

Some are smaller than others

[–] [email protected] 10 points 3 weeks ago

Not this knife

[–] [email protected] 76 points 3 weeks ago (1 children)

Sure? How many? Because I have some atoms at home and need a new knife

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.

But what would you do with the sliced cucumbers of millenia?

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.

[–] [email protected] 18 points 3 weeks ago (1 children)

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?

[–] [email protected] 2 points 3 weeks ago

You're doing it wrong. The mouse just diced a cucumber really, really l, small.

[–] [email protected] 3 points 3 weeks ago

Not with that attitude.

[–] [email protected] 6 points 3 weeks ago

Someone let Einstein loose, we must admit that violence is on occasion the only recourse.

[–] [email protected] 21 points 3 weeks ago

It’s also why cats are afraid of cucumbers.

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.

[–] [email protected] 1 points 3 weeks ago* (last edited 3 weeks ago)

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.

[–] [email protected] 9 points 3 weeks ago

That’s just one way to do it.

[–] [email protected] 5 points 3 weeks ago (1 children)

Okay, now explain bananas.

[–] [email protected] 7 points 3 weeks ago (4 children)

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.

(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.

[–] [email protected] 17 points 3 weeks ago (1 children)

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.

Bro, you should sharpen your knives.

Maybe it's not zooming in. Maybe the atoms of the cucumber are getting bigger! 😏

You're assuming the blade would be thinner than the nucleus, at the very least.

[–] [email protected] 6 points 3 weeks ago* (last edited 3 weeks ago) (1 children)

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.

[–] [email protected] 2 points 3 weeks ago (1 children)

You mean I’m just not cutting strong enough?

[–] [email protected] 12 points 3 weeks ago* (last edited 3 weeks ago) (2 children)

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.

[–] [email protected] 9 points 3 weeks ago

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!!

Well fission of uranium isn't hard. I want you to see to fission a C atom! XD

Don't eat fissile cucumbers.
