The hexagon was invented by Pappus Alexandria, centuries before the release of unrelated Belgian techno anthem Pump Up the Jam.

This is on my phone hope the text is readable.

It's less weird when you realize it's not a hexagon, it's a sine wave in cylindrical coordinates. There are a lot of negative feedback loops such that a sine wave can turn into a standing wave. You just have to get a little lucky with a couple important things like your rossby number et voila, hexagon.

Take this, bend it around the pole so it becomes circular.

sine waves aren't strictly an investment thing, they are more of a general math thing and can be used to model a wide variety of stuff (in this case this graph is for investing, but for example it comes up in physics a lot)

Keep going.... Sine waves are not an investment thing. They're a math thing that can be usefully applied to some things (eg. physics) or poorly applied to almost anything (eg. finance/econ).

I was just thinking of popping out my hex set so I can pop open Saturn

Because storms want to be circles but any given gas giants atmosphere is basically a series of nothing but storms and when you tile circles you get a hexagonal grid due to the spaces in between them?

Get out of here with your real answers. 😜

I think the actual answer even with this source is, we sort of have some clues, but we have more questions too.

Standing wave. Earth kind of has one in the jet stream (3 peaks and troughs though, usually), but you can't see it with visible light.

That’s actually the prevailing theory. A hexagonal shape is the path of least resistance for the wind patterns on Saturn. It probably really is that simple.

If only we could see other natural hexagons somewhere

I don't think it's completely unrelated though. I don't claim to understand what's actually going but seems to me that whatever winds are whipping about there could create fronts that are sort of similar as pressure as what happens with honeycombs. In one it's just the cells themselves create the pressure whereas here it's the giant planetwide storms.

Idk.

As a an interplanetary stormologist. Or a geometrisist.

The movement (kinetic energy) is the driver with the atmospheric patterns. There's no movement in the honey comb.

I mean, they lay round cells, but because they layer them tightly, they get squeezed in, and form a hexagonal pattern. Possibly drying also affects it idk much about bee-engineering, apologies.

Hexagons are just nature's way of making arrays of triangles.

Based on what I recall of the explanation by the person who figured it out: spinning makes fluid near the edge spin faster than fluid near the middle. The difference in speed creates a wave. Since it's finite and moving, the wave interferes with itself and because of math, makes a hexagon. Something about how the wave pattern changes density and brings different glasses to the surface on the planets.
Then they showed an example by spinning a bucket, and it kinda fell flat because they had to explain that a bucket isn't a sphere so you have to spin it just right to get it to work, but it did work in the end.

You get hexagons as well when you drill a countersink bit into plywood. Something something layers.

Did not know that so I looked on Google.

AI Overview That statement is incorrect. Drilling a countersink bit into plywood (or any wood) produces a smooth, conical hole, not a hexagonal one.

Followed by every article talking about why the bits make hexagons, with videos and pictures.

Haha I love AI! We're so close to AGI I swear bro!

Interesting, I've only had the hexagon thing happen to me in plywood, but it seems it can happen in regular wood as well.

Presumably to do with vibrations at a harmonic of the RPM?

Yeah apparently it has to do with the bit sort of sliding in behind the holes it carves out with its blades. Doesn't happen with a regular drill bit because those don't have sticky-out parts.

Incredible.

When my drill bits are super, super dull, they make smooth triangles. Like triangular shaped holes, with no true points or flat edges. If I get crooked while laying on it and drilling (not uncommon with a dull-ass bit) two lobes will stand out more clearly than the side I'm not leaning towards.

Not hexagons, and sure as hell not cones.

Now if they're sharp, it's just a fucking hole. Circular. Like they're supposed to be

Buy me new drill bits. for science

This was the topic of an awesome old web comic strip, I believe it was from smbc. It was a debate of two where one would simply state the existence of the hexagon, with increasing amounts of slurs. Banger.
