Rhombic Triacontahedron:

Also called the Triacontahedron

Catalan Solid

Dual of a quasiregular polyhedron

Dual of the Icosidodecahedron

It has 30 rhombic faces, 62 edges, and 32 vertices of two types.

One of the 9 edge-transitive convex polyhedra along with the 5 Platonic Solids, the 2 Quasiregular Convex Polyhedra, and the Rhombic Dodecahedron.

A visual study of the Icosahedron inside an Octahedron - and the remaining tetrahedral modules

The tetrahedral modules:

Buckminster Fuller came up with these modules and called them "S modules" or "S quanta modules".

Here is a helpful summary:

Since people are enjoying my slab bowl video so much, here's a video of me making The Shape:

Don't know what exactly to call it, but it brings me joy

Trans tetrahedron.

Proof of concept.

Would like to make one out of wood and make a paint dip jig to get the vertex coloring level.

Think I need to do some math first and color blue and pink based on equal area, instead of simply starting equidistant along the edges.

This permits every water molecule to be involved in four hydrogen bonds to four other H2O partners, as is shown in figure 6.41a. Hydrogen bonding in ice creates a three-dimensional network (figure 6.41b) that puts each oxygen atom at the centre of a distorted tetrahedron.

Pentagonal Icositetrahedron:

Also called the Pentagonal Icosikaitetrahedron

Catalan Solid

Dual of the Snub Cube

It has 24 irregular pentagonal faces, 60 edges, and 38 vertices of three types.

Chiral so it has two forms that are mirror images of each other.

1st iteration of the Sierpinski Tetrahedron - with an octahedron at the center.

The octahedron serves as "core".

Attached to that octahedron core are 4 tetrahedra.

Modules used: 24

[ 12 for the octahedron, 4x3 for the 4 tetrahedral tips ]

If I attach 4 more tetrahedral tips - so that all faces of the octahedron are stellated - it would turn into a stellated octahedron/stella octangula.

“An international collaboration of scientists has created and observed an entirely new class of vortices—the whirling masses of fluid or air.

Led by researchers from Amherst College in the U.S. and the University of East Anglia and Lancaster University in the U.K., their new paper details the first laboratory studies of these "exotic" whirlpools in an ultracold gas of atoms at temperatures as low as tens of billionths of a degree above absolute zero.”

“The unusual nature of the observed whirlpools here, however, is due to symmetries in the quantum gas. One especially fascinating property of physical theories, from cosmology to elementary particles, is the appearance of asymmetric worlds despite perfect underlying symmetries. For example, when water freezes to ice, disordered molecules in a liquid arrange themselves into a periodic array.

The spatial symmetry of a system is often readily identified—for example, a honeycomb has a periodic array of cells with hexagonal symmetry. Although the vortex medium used in this new work is a fluid rather than a solid array, it also possesses an internal set of hidden discrete symmetries. For example, one of the team's ultracold gases had the fourfold symmetry of a square, and another had the tetrahedral symmetry of a four-sided die, familiar to players of fantasy games everywhere.”
