1. Methods for dodecahedron, icosahedron, "football" and five kinds of random plates are presented in detail.

2. The dodecahedron (12 sided) shaped object you see actually consists of 12 speakers which allow for non-directional 360 degree sound field.

3. The results show that the fine-grained hypidiomorphic pyrite, with a crystal form of pentagonal dodecahedron, contains more Au than others.

4. The five possible normal polyhedrons are presented. It is impossible for crystals as well as their Brillouin zones to take the shape of normal dodecahedron.

5. A mathematic model of foam fractionation was set up based on the following assumptions: adsorption equilibrium, same bubble size and regular dodecahedron model of real bubbles.

6. The galaxy in question would really be behind you, but you're looking through one face of the dodecahedron as if it were a window.
