Episode notes

The search for order and disorder in the natural universe is something incredible fundamental. And physicists call it a phase, a diagram. They really want to understand, the first question you want to understand about matter is, what is its phase? Gram? If you have stuff that does this, how does how does it behave over time? This is a question that relates to physical systems like ouno electrons in material or spins in imaterialit relates to a phenomena like epidemic spreading. It relates to phenomena in echology and biology. So the applications are incredible, yes.

Physics is extremely good at describing simple systems with relatively few moving parts. Sadly, the world is not like that; many phenomena of interest are complex, with multiple interacting parts and interesting things happening at multiple scales of length and time. One area where the techniques of physics overlap with the multi-scale property of complex systems is in the study of phase transitions, when a composite system transitions from one phase to another. Nigel Goldenfeld has made important contributions to the study of phase transitions in their own right (and mathematical techniques for dealing with them), and has also been successful at leveraging that understanding to study biological systems, from the genetic code to the tree of life.
