[FRIAM] Any non-biological complex systems?

[Stephen Guerin]

Glen,

Let me take one claim at a time.

Do you agree that at least one of these is an example of a non-biological
complex system?

   - ferromagnetic system (described with ising model)
   - Bénard cell formation (convection)
   - Belousov–Zhabotinsky reaction
