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.

OMG yes I said "blast furnace to reduce steel". I meant "to reduce iron [to produce steel]". Obviously: What else would you use hydrogen for in a blast furnace?
But "reduce steel" is still, at least colloquially, correct for recycling steel: Scrap has rust on it so it also needs to be reduced. Which you would've realised instead of trying to turn this into a silly gotcha if you knew what you were talking about.
Go ahead, do tell me about your plan on how to produce steel, from ore, without getting fossil fuels or hydrogen involved. Charcoal? Could work, but I don't think the economics make sense.
