C960 - Goldberg vector (4,4)

The number of atoms in a Goldberg polyhedron is given by the formula N=20(h² + hk + k²). If h=k, one has N=60*h²=60*4² = 960 atoms in (4,4)-Goldberg polyhedron.

Hilbert's space filling curve

Chern showed me this bead model of Hilbert curve he made a few years ago when he was still an undergraduate student.

Poster for the 4th cross-strait theoretical and computational chemistry

I made another poster for the 4th cross-strait theoretical and computational chemistry (CTCC4) held at Kinmen university in Kinmen (金門) this week. This poster essentially has very similar connent but different pictures of beaded model as the one I made for the annual meeting of Taiwan's chemical society.

Two more toroidal carbon nanotubes

I made two more bead models for toroidal carbon nanotubes with 120 and 240 carbon atoms last weekend (Christmas holliday in many countries, but not here in Taiwan, :-)).
