Edit: I’m doing a show at Feastival this weekend! thebigfeastival.com/stages-and-experiences/the-exchange/matt-parkers-an-evening-of-unnecessary-detail I forgot to highlight in the video that we also got a bit obsessed with palindromes to go with the mirror balls. Which is why we called the workspace the BALLLAB. Also we named the installed the Hubbuhedron after the Cheese Hub.

A KZreadr and his team went to the cheese farm owned by the bassist of Blur in order to do a maths demonstration highlighting the yet to be named shape that is the convex hull of the compound shape formed by the ‘snubbed dodecahedron’ and it’s duel the ‘pentagonal hexacontahedron’ and they did this by making 6 disco balls.

I’m impressed with whoever came up with the snub dodecahedron. Even after seeing it, it isn’t obvious how much the pentagonal faces needed to be rotated in order to get the triangles to work out evenly.

@RichardHolmesSyr

9 ай бұрын

It's in the name: Archimedes. Or at least if he didn't come up with it he was one of the first to describe it, and the first to enumerate all the semiregular polyhedra (which are the prisms, the antiprisms, and the Archimedean solids). Pretty damn impressive when they didn't even have paper and Ticonderoga pencils let alone 3D graphics software. But you don't have to think of the snub solids in terms of expanded and rotated faces. You can get all the semiregular solids by considering all the ways regular polygons can meet at a polyhedral vertex, and in particular the snub dodecahedron is what results when you say "let's put a regular pentagon and four equilateral triangles around a vertex in the only way you can, and then see what unique polyhedron that gives you."

Would be interested to know how the final faces were added while keeping the tie ends inside, I have an idea for one way to do it but wonder if it's how it was done... (My thought is before adding the "keystone" face or collection of faces run cords thin enough to fit through the gap in an edge or vertex out through the far side of the thing, then loosely attach the cable ties and fix those cords to the tie ends, then use those to tighten everything down; that said I wouldn't be surprised if there wasn't some neater way to do it I wasn't thinking of)

Matt’s pronunciation of “duals” kept sounding like “jewels” to me. So at 7:07 I half expected him to say something about “holding up my jewels”.

Apparently this hectapentacontahedron is also called a joined snub dodecahedron, in reference to its being the hull of a snub dodecahedron and its dual

Now, take the kite-rhobus hectapentecontahetron, and superimpose it on its chiral twin (preserving the symmetry of the docecahedron) and take the convex hull of the result. What symmetry group does that yield?

That outro ... had me ... out of breath ... from laughter

How did you figure out / find out the dimensions and angles of the polygons to use? I don't see anything in the linked article giving that information.

The mirror-rotating, mirrored, mirrored, convex hulls of the compound shape formed by the snub dodecahedron and its dual, the pentagonal hexacontahedron. Sounds catchy enough to me, although to be fair I also live near Wales so many things sound concise and sensible. This video could have only been improved by 2 things: - The seat on the ride at the end coming around empty on the last rotation (obviously by means of camera trickery, not actually launching Matt into an unsuspecting tapas stand. - A cheese carved into the shape of a kite-rhombus hectapentacontahedron.
