Look at these images from the wiki article. Here we see Lisi's breakdown of the hierarchical levels of matter.
|Levels of magnification: |
1. Macroscopic level - Matter
2. Molecular level
3. Atomic level - Protons, neutrons, and electrons
4. Subatomic level - Electron
5. Subatomic level - Quarks
At the smallest level of instantiation, Lisi proposes this "most beautiful" geometric figure, called E8.
