Why doesn’t he just make the square bigger? That’d be more efficient.

[–] EddoWagt@feddit.nl 2 points 6 hours ago

That's not more efficient because the big square is bigger

[–] bitjunkie@lemmy.world 15 points 22 hours ago (3 children)

It's important to note that while this seems counterintuitive, it's only the most efficient because the small squares' side length is not a perfect divisor of the large square's.

[–] jeff@programming.dev 9 points 22 hours ago (2 children)

What? No. The divisibility of the side lengths have nothing to do with this.

The problem is what's the smallest square that can contain 17 identical squares. If there were 16 squares it would be simply 4x4.

[–] bitjunkie@lemmy.world 1 points 2 hours ago

And the next perfect divisor one that would hold all the ones in the OP pic would be 5x5. 25 > 17, last I checked.

[–] Natanael@infosec.pub 13 points 21 hours ago

He's saying the same thing. Because it's not an integer power of 2 you can't have a integer square solution. Thus the densest packing puts some boxes diagonally.

[–] sga@lemmings.world 3 points 22 hours ago

this is regardless of that. The meme explains it a bit wierdly, but we start with 17 squares, and try to find most efficient packing, and outer square's size is determined by this packing.

the line of man is straight ; the line of god is crooked

stop quoting Nietzsche you fucking fools

[–] Serinus@lemmy.world 181 points 1 day ago (7 children)

With straight diagonal lines.

Oh so you're telling me that my storage unit is actually incredibly well optimised for space efficiency?

Nice!

[–] SpongyAneurysm@feddit.org 5 points 1 day ago (2 children)

Now, canwe have fractals built from this?

[–] Lemmisaur@lemmy.zip 17 points 19 hours ago (1 children)

Say hello to the creation! .-D

(Don't ask about the glowing thing, just don't let it touch your eyes.)

[–] SpongyAneurysm@feddit.org 7 points 19 hours ago (1 children)

Good job. It'skinda what I expected, except for the glow. But I won't ask about that.

[–] BowtiesAreCool@lemmy.world 4 points 18 hours ago

The glow is actually just a natural biproduct of the sheer power of the sq1ua7re

[–] mEEGal@lemmy.world 5 points 1 day ago

"fractal" just means "broken-looking" (as in "fracture"). see Benoît Mandelbrot's original book on this

I assume you mean "nice looking self-replicating pattern", which you can easily obtain by replacing each square by the whole picture over and over again

[–] Squalia@sh.itjust.works 40 points 1 day ago

Here's a much more elegant solution for 17

[–] Psaldorn@lemmy.world 52 points 1 day ago

You may not like it but this is what peak performance looks like.

[–] janus2@lemmy.zip 68 points 2 days ago (1 children)

if I ever have to pack boxes like this I'm going to throw up

If there was a god, I'd imagine them designing the universe and giggling like an idiot when they made math.

Bees seeing this: "OK, screw it, we're making hexagons!"

[–] raltoid@lemmy.world 30 points 1 day ago (2 children)

Fun fact: Bees actually make round holes, the hexagon shape forms as the wax dries.

[–] FiskFisk33@startrek.website 1 points 9 hours ago* (last edited 9 hours ago)

come on now, let them cook, trust the process

[–] starman2112@sh.itjust.works 2 points 23 hours ago

But fear not, bees are still smart! Mfs can do math!

Can someone explain to me in layman's terms why this is the most efficient way?

[–] tiramichu@sh.itjust.works 143 points 1 day ago* (last edited 1 day ago) (7 children)

These categories of geometric problem are ridiculously difficult to find the definitive perfect solution for, which is exactly why people have been grinding on them for decades, and mathematicians can't say any more than "it's the best one found so far"

For this particular problem the diagram isn't answering "the most efficient way to pack some particular square" but "what is the smallest square that can fit 17 unit-sized (1x1) squares inside it" - with the answer here being 4.675 unit length per side.

Trivially for 16 squares they would fit inside a grid of 4x4 perfectly, with four squares on each row, nice and tidy. To fit just one more square we could size the container up to 5x5, and it would remain nice and tidy, but there is then obviously a lot of empty space, which suggests the solution must be in-between. But if the solution is in between, then some squares must start going slanted to enable the outer square to reduce in size, as it is only by doing this we can utilise unfilled gaps to save space by poking the corners of other squares into them.

So, we can't answer what the optimal solution exactly is, or prove none is better than this, but we can certainly demonstrate that the solution is going to be very ugly and messy.

Another similar (but less ugly) geometric problem is the moving sofa problem which has again seen small iterations over a long period of time.

[–] DozensOfDonner@mander.xyz 23 points 1 day ago (4 children)

Lol, the ambidextrous sofa. It's a butt plug.

Is this confirmed? Like yea the picture looks legit, but anybody do this with physical blocks or at least something other than ms paint?

[–] deaf_fish@midwest.social 9 points 1 day ago* (last edited 1 day ago)

It is confirmed. I don't understand it very well, but I think this video is pretty decent at explaining it.

https://youtu.be/RQH5HBkVtgM

The proof is done with raw numbers and geometry so doing it with physical objects would be worse, even the MS paint is a bad way to present it but it's easier on the eyes than just numbers.

Mathematicians would be very excited if you could find a better way to pack them such that they can be bigger.

So it's not like there is no way to improve it. It's just that we haven't found it yet.

[–] crmsnbleyd@sopuli.xyz 8 points 1 day ago (2 children)

Proof via "just look at it"

[–] peteypete420@sh.itjust.works 1 points 17 hours ago (1 children)

I feel like the pixalation on the rotated squares is enough to say this picture is not proof.

Again I am not saying they are wrong, just that it would be extremely easy make a picture where it looks like all the squares are all the same size.

[–] crmsnbleyd@sopuli.xyz 2 points 11 hours ago

I was joking about the proof but there's a non-pixelated version in the comments here

[–] CheeseNoodle@lemmy.world 10 points 1 day ago

Visual proofs can be deceptive, e.g. the infinite chocolate bar.
