@otherlab analysis argues that US can 100% decarbonize with existing tech: electric vehicles, heat pumps, solar on every roof, etc. https://www.otherlab.com/blog-posts/green-new-deal-how-much-does-fixing-climate-change-cost-the-us … These changes will pay for themselves in time due to greater efficiency, just needs to be coordinated and financed.pic.twitter.com/g4B6EBjWq4

The CA fires and PG&E bankruptcy is an opportunity to rethink our power grid. Properly accounting for the externalities of power transmission make local renewables, storage, and microgrids more attractive. Best intro I've read on this subject, by

It's always great to find more ways of seeing the shapes and how they can be constructed! I *think* you can make all the Archimedean Solids with truncation (like the above animation), expansion (below), and that snub operation.pic.twitter.com/FjlhfRqvhs

I'm not sure how you can get the "snub" shapes with this strategy though. These necessarily involve a "twist" and indeed the snub shapes are chiral (have a handedness). Here's a snub cube and snub dodecahedron:pic.twitter.com/uytlaqccMN

I can definitely see many of the Archimedean Solids as the interim stage of a transformation between Platonic duals, for example icosidodecahedron is halfway between icosahedron and dodecahedronpic.twitter.com/Xj9csdoU07

A d10 is a Trapezohedron https://en.wikipedia.org/wiki/Trapezohedron … These aren't traditionally considered Catalan Solids but they arguably should be because they satisfy the properties:
Faces are identical
Angles around any vertex are equalpic.twitter.com/dFSAR15dRt

We are making a small batch of Sun Seed Kits!

Check it out if you're interested in making your own color-changing, geometric sculptures. Our crowdfund ends in 2 days!pic.twitter.com/hrPMmiPFzCPrikaži ovu nit -
The "Lotus" Sun Seed, designed by
@mokeymuffin, is based on the pentagonal hexecontahedron. It has 12 large flowers where 5 pieces come together and 80 small flowers where 3 pieces come together.pic.twitter.com/DtI9FM6HpL

I based my "Mint" Sun Seed on the rhombic triacontahedron. There are 30 identical pieces. Every vertex is a flower. Can you find the big flowers with 5 petals and the small ones with 3 petals?pic.twitter.com/J3vHf4dM9m

The properties of the Catalan Solids were perfect for evoking the symmetries of flowers and microscopic plant life that inspired our project. Below is an electron microscope image of pollen from a variety of plants.pic.twitter.com/v6ehHdbWtq

I came upon the Catalan Solids while working on "Sun Seeds", a sculpture collaboration with
@mokeymuffin and@notlion.pic.twitter.com/mloEJDCNIPPrikaži ovu nit -
Vertices are identical
Angles around any vertex are equal
At every vertex, the angles go around regularly. But there are two classes of vertices, those where 5 shapes meet and those where 3 shapes meet. These correspond to the pentagons and triangles of the dual!pic.twitter.com/OJCFNLwfuX

Faces are identical
Faces are regular polygons
On the rhombic triacontahedron, the faces are all the same but they're no longer regular, in this case they're a rhombus (diamond) shape.pic.twitter.com/Z9D4vb1Oiw

For example, the dual of the icosidodecahedron (an Archimedean Solid with 32 faces and 30 vertices) is the rhombic triacontahedron (a Catalan Solid with 30 faces and 32 vertices).pic.twitter.com/zBK92I6k3e

If you take the duals of the 13 Archimedean Solids, you get the 13 Catalan Solids! Because we're swapping faces with vertices, all the properties also swap!

The dual of an icosahedron (20 faces, 12 vertices) is a dodecahedron (12 faces, 20 vertices).pic.twitter.com/hMjtVmkAxk

The dual of a cube is an octahedron. A cube has 6 faces and 8 vertices. An octahedron has 8 faces and 6 vertices. You replace every face by a vertex, and every vertex by a face.pic.twitter.com/nQ9oDVMe4n
