If you are here asking: "Is this a science meme?"

Probably, yes. We use the Dawkins definition of meme: a replicating idea, not just an image macro with a fact on it. A good post here doesn't need to teach you something. It needs to make you ask something: who, what, where, when, and especially why or how.

Science isn't a filing cabinet of facts, it's a conversation. For example, a photo of an eel or other localized wildlife counts because most people never see one, and wonder is the first step of inquiry. A car meme counts if it makes you curious about what's under the bonnet. If you want to talk about something you noticed in the world, chances are someone else wants to talk about it too.

We moderate for vibe, not category. Pruning is light, especially where a post creates interesting discussion. Experimenting is encouraged.

See the pinned paper on Shitposting as Public Pedagogy if you want the academic case for why this works.

Wouldn't that be uranic dihydrogen peroxide?

I'm pretty sure dioxide peroxide is not a thing.

Listen here, you piece of shit, the original image is h2o4u which reads as water for you. Stop inventing words

[–] Reborn_Mormon@lemmy.world 1 points 9 hours ago

I'll boof that ish if you will

[–] Etterra@discuss.online 50 points 1 day ago (1 children)

Johnny was a corporate stooge,

but Johnny's words untrue;

what Johnny sold as H2O

was H2O4U.

[–] Reborn_Mormon@lemmy.world 4 points 9 hours ago

Johnny knew not water

For he forgot vater

My father is he who speaks through me

And thus I express simply

That ain't water I just drank

It's getting dark, I'm gunna have one last wank

Little Johnny took a drink but now will drink no more

For what he thought was H2O was H2SO4

[–] grue@lemmy.world 43 points 1 day ago (1 children)

Fun fact: unlike some other site that shall not be named, Lemmy's markdown can do subscripts!

Little Johnny took a drink
but now will drink no more
For what he thought was H~2~O
was H~2~SO~4~

Really? It's the squiggly to make subscript? I thought that was used for strike through?

[–] charonn0@startrek.website 15 points 1 day ago* (last edited 1 day ago)

Two squiggles for ~~strikethrough~~; one squiggle for ~subscript~; and no squiggle for you!

[–] grue@lemmy.world 7 points 1 day ago (1 children)

Strikethrough is ~~double-tilde~~ double-squiggly.

[–] sqw@lemmy.sdf.org 0 points 9 hours ago (2 children)

where's the reference for these?

[–] grue@lemmy.world 2 points 8 hours ago* (last edited 8 hours ago)

I don't think it's complete, though; some you just have to discover for yourself (or guess from familiarity with Markdown on other platforms).

[–] sqw@lemmy.sdf.org 0 points 8 hours ago

ah , seems my client has some helpful shortcuts

cool ~stuff.~

Neat, I've never seen that version before. The one I know is:

Johnny was a chemist's son
but Johnny is no more.
What Johnny thought was H2O
was H2SO4.

Strong acids are weak, you'd notice the boiling acid flavor and spit it out with the rest of your mouth lining right away.

[–] ranzispa@mander.xyz 1 points 19 hours ago

Doubt you'd die from drinking a bit of sulphuric acid, probably would spit it out as soon as you notice your tongue is burning anyway.

[–] solidheron@sh.itjust.works 22 points 1 day ago (2 children)

Is H~2~O~4~U chemically possibly? I feel like you could make a chain out of the oxygens and put hydrogen at both ends but I don't hear anything more that O~3~

[–] Earthwormjim91@lemmy.world 28 points 1 day ago (1 children)

Not as written. But uranyl peroxide is a thing.

There’s UO~4~·4(H~2~O) studtite and UO~4~·2(H~2~O) metastudtite

This is what i missed about old reddit the most.

Love it 😘

I don't want to be guy who needs to read the NMR spectra of this stuff.

[–] OwOarchist@pawb.social 17 points 1 day ago (1 children)

Is H2O4U actually possible to synthesize? Is it stable?

Would it be a liquid at any reasonable temperatures?

[–] Not_mikey@lemmy.dbzer0.com 27 points 1 day ago (2 children)

Tetraoxidane (H2O4) is very unstable by itself, and I doubt adding a uranium into the mix would stabilize it

[–] OwOarchist@pawb.social 17 points 1 day ago* (last edited 1 day ago) (2 children)

Hm... I'm guessing that adding Uranium to that would make it quickly oxidize, and instead of H2O4U, you'd get mostly U3O8 (the most stable Uranium oxide) and a bunch of H2O and Hydrogen gas.

[–] Fluke@feddit.uk 10 points 1 day ago (1 children)

And a lot of heat. If I had to guess, I'd bet on that being a... "rather energetic" exothermic reaction.

[–] Dpek@lemmy.zip 1 points 7 hours ago

What is heat but shaken atoms?

[–] fartographer@lemmy.world 10 points 1 day ago (1 children)

Surely if you shook the bottle well, the ingredients would recombine like a vinaigrette, and the intended flavor could be appreciated.

[–] wonderingwanderer@sopuli.xyz 7 points 1 day ago

No way to know until you try

[–] KenOh@feddit.online 7 points 1 day ago

Something something H2SO4

Awww, the redditor by the name TheZyde understood the joke!
