  2. Keep it rooted (on topic).
  3. No spam.
  4. Infographics welcome, get schooled.

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.

The nearly perfectly symmetrical shape makes me think its due to the electromagnetic fields when current is passing through the socket to whatever is plugged in, but I have no idea why such a small amount would have such a dramatic effect on the mold.

[–] Soapbox@lemmy.zip 31 points 2 months ago (1 children)

I was thinking it might just be heat from the wiring or plugged in devices keeping it too dry for the mold.

It could also be that they needed to mud/tape around the opening for the plug in the drywall/plaster and it changed the consistency/chemical makeup just enough to not be as friendly to the growth of mold (less moisture/denser etc)

Heat spread is symmetric if the material is lol

[–] M137@lemmy.today 2 points 2 months ago

Which it is...? It's symmetric to two outlets next to each other giving heat, which is the case. And reality is never perfect, it wouldn't be an absolutely perfect pill shape for so many reasons.
