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.

It's simple, cells are fractions.

[–] fidodo@lemmy.world 1 points 2 years ago (1 children)

But it's turning 1 into 1/2+1/2 which is different than dividing by 2.

[–] sorhead@lemmy.world 2 points 2 years ago (1 children)

No, it's dividing 1 by 1/2 leading to 2.

The correct answer

[–] I_Has_A_Hat@lemmy.world 24 points 2 years ago (2 children)

A fundamental disregard for sets and their importance in higher mathematics.

This could just as easily had been a reply with:

Computers multiply by adding, subtract by adding, i'm not sure how division goes but i'm sure that's addition too.

Looked into it. It literally is.

The other replies are simplifying too much. Just adding or subtracting in a loop would be far too slow.

A multiplier will find the partial products by using AND gates, and then sum them, which is very similar to long multiplication as they teach you in school. This article explains it pretty well.

Division is more complicated. It's sort of done like long division, but apparently that is slow and there's some magic with two's complements that can make it faster. Honestly I don't fully understand it yet.

[–] SturgiesYrFase@lemmy.ml 2 points 2 years ago

That article was really good. I feel like if someone explained it to me at a pub or party I could somewhat talk about it without sounding like a total ludite.

[–] Johanno@feddit.de 4 points 2 years ago

Once you go down to logic gates. A XOR gate for example makes 1+1 = 0

[–] Xavienth@lemmygrad.ml 2 points 2 years ago (1 children)

Subtract divisor from dividend until you hit zero. Number of subtractions is the quotient. Don't ask about non-whole numbers.

[–] Omega_Haxors@lemmy.ml 2 points 2 years ago

The remainder is the amount of overflow when you go below zero.

[–] Omega_Haxors@lemmy.ml 2 points 2 years ago* (last edited 2 years ago)

It recursively subtracts until the number goes at or below zero. The iterations is the output and the reminder is how much it went below zero.

Clever and I get the joke and it made me smile. If I recall my biology from 20 years ago I think the cell makes duplicates of its chromosomes then splits apart. So you have two cells inside one membrane that separates, 2 / 1 = 2. The way I first thought about it was one cell splitting in half, so half goes to one cell, the other half with the other, 1 / .5 = 2.

In short, I think the math works out fine, but the language you use to describe it can lead to comedy gold. You could say cells reproduce by division? I don't know, I'm not a biologist or mathematician. I'm a toilet poster.

No comments about Amitabh Bachchan's use for meme. Well it should have been a long time coming, I'm glad that it's now here.

[–] Rascabin@lemmy.ml 3 points 2 years ago (1 children)

Bollywood itself is a meme 🤭. Just watch their version of The Matrix. Dude starts singing with "Trinity", like wtf!??

[–] faintwhenfree@lemmus.org 2 points 2 years ago

Lol it gets wtf long before he starts dancing with trinity.

[–] OpenStars@startrek.website 5 points 2 years ago

That's the problem whenever math meets physics: the former wins in the theory, but in the real world physics always triumphs:-).

https://en.wikipedia.org/wiki/Partition_of_a_set?wprov=sfla1

The sets in [partition] P are called the blocks, parts, or cells, of the partition.

The number of cells in partition is >= 1.
