Metaphysical - What are things really?6. Chinese Cracked Ice Pattern. When I first saw it several years ago in a book about Chinese architecture, I loved it. Here's a mathematical description. I got to thinking about these patterns when I read about "Li Symmetries" on pg. 120 of Quadrivium, a book with many illustrations from early thought in math, geometry, and music. The short description included a reference to Alan Turing, who wrote "The Chemical Basis of Morphogenesis". You can see some examples of modern application of this idea in this Wired article. While these look like fractals, they seem somehow different. Oddly, searching for "Li Symmetries" online turns up no results. So where did that name come from?
