Session 12: Perception, Action, and Mind

(Back after a bit of a hiatus - have still been chipping away little by little in the background all the while)

Thread/
On:

How units, especially complex multicellular animals, mainly get around in the world in a macroscopic way.

Issues to do with perception/action and in some sense mind.

1/n
Gigerenzer, Gut Feelings -"Many skills lack descriptive language"
JJ Gibson -"The environment isn't the same as the physical world"
Maturana etc. -"The [eye's] operations thus have much more the flavour of perception than sensation, if that distinction has any meaning now"

Session 11: The Organisation and Dynamics of Living Agents

Thread/
Intuitively much of the real world is alive, whatever that might mean.

The kind of complexity that we observe in living systems is really an order of magnitude (however you might want to measure that) more complex than anything we see in the 'merely' physical world

1/n
Physical systems can display non-linear behaviours, pattern forming processes, etc.

When we get to the realm of the living almost none of our reductionistic concepts are too helpful, outside of very narrow contexts

Session 10: Variety and Entropy

Thread/
To account for increasingly large and complex systems, we must take an ensemble perspective.

1/n
Instead of thinking about what the system is going to do, start thinking about what can the system possibly do what's the state space? what could it possibly do? what configuration could it possibly have? The complement of that is what possibility won't it manifest/actualise?

Session 8: Fat Tails and Extremes

thread/
An important feature of systems to pay attention:

What is independent?

What is not independent?

There's a lot of talking past one another in the complexity sciences.

Session 7: Stochastic Processes

thread/
Determinism can only take us so far - whether it's a fundamental "randomness" or epistemological limitation, doesn't really matter, probabilistic processes become necessary to start dealing with systems & thinking about their future paths/trajectories/possible trajectories.

1/n
Epistemological limitations like chaotic dynamics or computation irreducibly introduce uncertainty future states of system.

Session 6: Networks and Connectivity

thread/
Networks are the organisation structure that shape the interactions of a system.

1/n
Intuitively complex systems have a lot of internal connectivity (complexity depends on connectivity).

Session 5: Fractals and Scaling

(Thank you Benoit B. Mandelbrot)

thread/
Hysteresis is a basic form of memory.

It matters where you come from.

1/n
There are tools that people bring to bear that become selective mechanisms over the possible objects of study and so we get this hugely biased sample of what we consider normal/regular/typical.

Session 4: Cellular Automata, Self-Organisation, and Pattern Formation

thread/
How do we get Order without a creator?

Self-organisation

DNA is not a blueprint, a common but bad metaphor.

DNA serves as a set of internal instructions to tell a cell what do I do given these inputs from my local environment.

@chrismanfrank & @bavoter appear:

Imparts some wisdom from Dr. Dwanye Beck.

'Diversity is important in emulating natural systems.'

'Pests, weeds, & disease are a sign of a lack of diversity. Nature's way of replacing the diversity that was lost.'

For the past month or so I've been taking @normonics ACS101 which I can thoroughly recommend.

Seeing as we're about half the way through #ACS101 I thought I give a recap of my notes of some of the highlights so far.

/thread
I've being going back through the sessions so far of ACS101 #SpringA2021 in my spare time.

It's remarkable how much more everything clicked that much more the second time around after the time absorbing everything.

Truly no book is read twice by the same man.
