The main thing I learned from this video is that Mat Parker should not be left alone in a hotel room for to long without adult supervision, he'll go mad with boredom and start making strange shapes and rambles on and on on the balcony. Interesting video though.

UnqualifiedAdvice Exactly!

They say that mathematicians are people who turn coffee into theorems. Now we learn they may also turn instant coffee (and sugar and brochures) into geometric shapes ...

The Bilinski dodecahedron, rhombic icosahedron, rhombic triacontahedron, and rhombohedron are the four unit shapes in a quasicrystal. All the faces are golden rhombi, and it has 5-fold icosahedral symmetry. Subscribed.

Not fully platonic... so, geometry with benefits?

+1 for shading Nescafé as "a Coffee like substance" :-)

One thing to mention is that if you continue the process of "removing a belt of rhombuses" with the Bilinski dodecahedron, you can actually create a rhombic hexahedron (looking like a partially squashed cube). There are actually an infinite number of possible rhombic hexahedrons (where the diagonals have a ratio between 1:1 [cube] and 1:√3 [basically a degenerate hexagon]), but the golden rhombic hexahedron is unique in that it is the only rhombic hexahedron that can "add" a belt of identical rhombi to create a rhombic dodecahedron.

Thanks Matt. I have used geometry in my craft works for quite some time, including the rhombic model. Just realised there was a big story behind it. Quite interesting indeed.

I love the part when the person walks onto their balcony, looks over at Matt talking about rhombic dodecahedrons to a camera, and then immediately turns around and goes back inside.

The golden ratio is officially a Parker square.

I like that person that comes into the image and is seemingly consumed by the Dodecahedron. Truly a mystery that will never be solved.

This is awesome. You're amazing, Matt!

You deserve a million subscribers. This video was AWESOME!!!

I jumped from my seat when I realized the unexpected relation to the Rhombic Triacontahedron. Really exciting video, Matt!

As you can no doubt deduce from what you know about the Rhombic Icosahedron, the shape made by two opposite edges and an imaginary pair of parallel lines through the Icosahedron connecting the two opposite edges is a golden rectangle. I love polyhedrons and phi, and I literally cheered out loud when you declared that the Bilinski Rhombic Dodecahedron was made up of Golden Rhombi. I love this stuff.
