::: spoiler Transcript An informational diagram showing different (bad) ways to cut a circular pizza.
- A grid cut, labelled “Tic-Tac-Toe”
- a regular 8-way cut, but the middle is very off center, labelled “Off-Center Inequality.”
- A six-slice cut where each cut is a sinusoidal curve, labelled “Apple Beachball”
- A spiral that goes all the way to the middle, labelled “Spiral Cut”
- Looks normal, but is labelled “Just draw the lines on with a sharpie”
- Regular shaped slices cut out of the middle of the pizza in random positions, labelled “Why”
- A side view, showing two long horizontal cuts through the entire disc, labelled “Layer Cake”
- Mostly diagonal lines splitting the pizza into shapes, labelled “Tangram”
- Two identical pizzas, labelled “Banach-Tarski” :::

How is this not an xkcd comic?

Because Banach-Tarski doesn't work in 2d and that's not the sort of mistake Randall could get away with without drowning under messages um-actually-ing him.

But a pizza is 3D.

Not the way my aunt makes it. A piece of paper is often thicker.

why? that's a good thing. it means more toppings by mass
diaphragmwp@discuss.tchncs.de · 1 pts · 57d
You put toppings on in 3D.

The spiral doesn't even cut it into pieces. It's still one

You must be looking for the article how to cut a pizza into multiple slices. This article was called 9 ways to cut a pizza.
Obviously a more USEFUL article would be 9 ways to cut a pizza into equal slices.

You can eat the whole thing like fruit-by-the-foot

I definitely saw a comic strip about this exact thing being the right way to cut a pizza for one.
Followed by a demonstration of someone eating the whole thing in one long continuous grind without their hands.

You mean it's... One PIEEECCEEE?

wouldn't the Babach-Tarski cut end up with both pizzas having the same size as the original?
panda_abyss@lemmy.ca · 5 pts · 58d
Maybe that was the original size for that one
cannedtuna@lemmy.world · 5 pts · 58d
My guess is it’s smaller due to the spacing of the comic, more like it’s zoomed out
FluorideMind@lemmy.world · 16 pts · 58d
Ok hear me out. Off center inequality is the best choice. It gives the most options for portion size, like maybe I don't want 2 slices. Maybe I only want 1.4 slices. With all others, that isn't possible.

You share your pizza ?
LastYearsIrritant@sopuli.xyz · 4 pts · 57d
It's so you can start with the big slices, and then slowly eat the smaller slices until nothing else fits. It makes it so you don't end up with a half-eaten slice.

You don't finish your pizza ? Yeah I'm fat and I know why :(

Man I had to look that last one up and I still don’t fully understand it.
Banach-Tarski

It's pretty simple, really. There's a mathematical way of creating a complete cover of all points within a sphere in a finite number of subsets in such a way that those finite subsets can be rearranged into two complete spheres of the same size.
It's kind of like how there are exactly as many points between 0 and 1 on a number line as there are between 0 and 2, so if you take a 0 to 1 segment, and then multiply all distances by 2, you can cut it into two pieces with exactly as many points as the original 0 to 1.
This is the sort of thing that only works with mathematical abstractions, which is why it's paradoxical. You sure as heck can't do this with a pizza, even if it's technically isomorphic to a sphere.

Imagine a stretchy piece of elastic that doesn't change cross-section when pulled and doesn't snap back. (This is mathemagic elastic. A regular rubber band gets thinner and narrower in cross-section when pulled. Also they tend to snap back.)
Stretch it to twice its length and then cut it at the halfway point. You now have two stretchy pieces of elastic just like the first one.
If this bothers you that something is apparently being created from nothing, that's why Banach-Tarski is called a paradox.

spiral cut and then lower it over a 3D printed spiral cone thing on top of a lazy susan. now everyone gets to cut a curved pizza ribbon from the bottom
the guests love it and post it all over their socials. the catering staff has a blast making fun of it (and posting it all over their socials)

Honestly, kinda digging the tangram method.

I recall reading somewhere that if you cut the pizza using the "off-center inequality" method, then have four people each take a piece plus the one directly across from it they will all end up with an equal amount of pizza.
Raja@lemmy.world · 2 pts · 57d
That doesn't seem right. If you imagine moving the "off-centre" point towards the edge, then two of the slices will cover most of the pizza, so the remaining slices can't add up to enough.
It would make a fun geogebra animation.

I was close, it's two people not four:
