My friend and sometimes tennis partner David just emailed me this link to a story at Phys.org titled “Through a sensor, clearly: Complex systems made observable.” It’s right up my alley, he thought, and right up our alley, I thought.
Now, I don’t have either the math or the graphical chops to get under the hood of this research. But I think I understand what they’re up to, and I think I know enough to spot a couple of places where questions might be asked. For example, if I understand correctly we’re talking here about describing a snapshot of a complex system; it’s my impression that once the system is actually complexing, the data-crunching becomes prohibitive. But if so, one moment of a dynamical system is of limited utility, since it captures the system but not the dynamical. If I’ve understood correctly, this is not a criticism, but an appreciation of where we are in the learning curve.
I also appreciate that there’s a devil in the details of observer design; that is, the sensors have to be able to tell the difference between information and noise, nonlinearity and randomness. In effect this means that the sensors have to be able to learn to discriminate intelligently, which most human brains are not that great at. But they’re just doing feasibility at this stage, and I gather they think if they can use graphical modeling to specify some system parameters, they can eventually walk-in the data-gathering to yield more satisfying descriptions.
Well, I bet about half of what I just said is at least a little bit wrong. What I hope is that I’m just wrong and not ‘not even wrong‘, that is, that I know at least enough to be worth talking to further by someone with a better understanding. And this brings me to the question for today, which is this. Given that the project here is to represent and understand complex systems, which explicitly include “biological systems [or] social dynamic system[s] such as opinion or social influence dynamics” – that is, to start with, citizenship and life itself – what responsibility does a university general education core program have to bring students up to a kind of elementary competence where they can participate responsibly in this kind of conversation? What and how would we have to teach to make that so? And what in the reverend paleo-disciplines and contents might need to retool or move aside to enable this development?
UPDATE: if nothing else comes of this post, at least I’ve learned what it means to be ‘fractally wrong‘.
