A new display case

I have a new display case for some of Chern's and my beadworks in the chemistry building of National Taiwan university.

Four face-sharing pentagonal dodecahedra

E. A. Lord, A. Mackay, and S. Ranganathan described in their book, "New geometries for new materials", a simple cluster consisting of four face-sharing pentagonal dodecahedra arranged in a tetrahedral configuration (pp.48). Here is a bead model of this cluster.

In their book, there are more clathrate structures that one might be able to construct with beads.

Clathrate cluster

I bought some more green rice-shape beads last week and managed to finish this interesting clathrate cluster of 60 dodecahedra in the last weekend. One can still see deformation of many dodecahedra in this clathrate cluster though.

Three beadworks for the Joint Mathematical Meeting

Chern and I submitted three beadworks, P-, D- and G-TPMSs, for
the mathart exhibition of Joint mathematical Meeting which is going to be held in Boston next January.

Here I took the two photos from the JMM site:
the first one is the G-TPMS view from another angle:

and also the D-TPMS

Two more posters for my exhibition

I made two more A3-size posters with the bead model of gyroidal graphitic surface for the exhibition, "The Fabulous World of Beaded Molecules 串珠幾何的異想世界", on Wednesday.

Exhibition : The Fabulous World of Beaded Molecules 串珠幾何的異想世界

In conjunction with the special Marie Curie’s exhibition for the international year of chemistry, I am going to have a joint exhibition, "The fabulous world of beaded molecules (串珠幾何的異想世界)", for my beadworks here in the chemistry department of National Taiwan University from 10/9-10/20.




I made a few posters for this event.
