Episode notes

You would never know it just by looking at it. You'll have to study it thwith physitical physics techniques. But really, whan i being is thatyouyou have to have what's called an absorbing state. Once you get into it, then you can't get out of it again. So for example, ia ec the stem, if, you know, if you eat all the prey, then then the predators, the pray are dead. The predators have now got nothing to eat, so they die. Everything dies, and then the uca system is just dead forever. That's an example of an absorption state.

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.
