Tommy the Russkie Tank-tank

Sunday, April 16th, 2017

[ by Charles Cameron — A Russian tanker-toy saga ]
.

Another contribution to the maxcro / micro, war / games displays in my mental cabinet of wonders:

I’m sorry, this was about the only screen-grab I could manage that showed both the toy tank and its war-fighting seniors. In the children’s story, the toy tank gets left at the tank museum overnight, and is shocked and awed by the realities of which it is but a simulacrum — the OT 76, T 72, and most particularly the T-14 Armata super-tank.

The equation war : war games :: T-14 : toy tank eiher understates the significnce of the T-14 or exaggerates that of the toy — but equations between simulacrum and reality lie at the heart of such philosophical excursions as Baudrillard‘s Simulacra and Simulations, with its phony epigraph, a simulacrum of a quote from Ecclesiastes:

The simulacrum is never that which conceals the truth—it is the truth which conceals that there is none.

In the case of this children’s book, we can postulate another equation: Russia : propaganda :: factory : advertising.

But see for yourself, some of the details are hilarious:

Flight paths in simulation and reality

OTOH, in reality:

OTOH, in simulation:

The simple excellence of rulesets in agent-based modeling is wonderfully demonstrated by the way the eye can “recognize” the movements on a flock of birds or a school of fish in Craig Reynoldsboids — rulesets notably simpler than the explanations for flocking behavior previously suggested by biologists.

Metacognitive question: what’s the cognitive means by which we humans can “see” that the boid simulation is a sufficiently accurate representation of birds flocking and fishes schooling to account for them? — and ditto for birds flocking and fishes schooling, how do we “see” them as naturally equivalent? — and ditto for those birds flocking and fishes schooling and our earlier biological accounts of their behaviors? —

With a hypothesis, we can test by finding predictable or disconfirmative instances beyond those on which the hypothesis is suggested.. but when the similarity is visually perceived?

On play as wildness

There’s a certain let-your-hair-down quality to play.

It appears that one Tausendsassa Friedensreich Regentag Dunkelbunt Hundertwasser said or perhaps wrote, muttered, whispered, shouted, or simply thought out loud, “the straight line is a godless line” — at any rate, someone noticed and recorded the phrase, and now it’s scattered across the net and difficult to track to its source.

But we do love order, don’t we?

And so the rivers on our hexagonal maps all too easily follow the hexagons..

when they’d more realistically cross over them, following their own courses:

and note how easily even our efforts to bring natural variety to our hexagonal mappings conform more to hexagons than to variety.

Zennist Thich Nhat Hanh in Listening Deeply for Peace writes:

A traditional Vietnamese Zen garden is very different from a Japanese Zen garden. Our Zen gardens, called hon non bo, are wild and exuberant, more playful than the formal Japanese gardens with their restrained patterns. Vietnamese Zen gardens are seriously unserious. For us, the whole world is contained in this peaceful place. All activities of life unfold in true peace in the garden: in one part, children will be playing, and in another part, some elderly men will be having a chess game; couples are walking; families are having picnics; animals are free to wander around. Beautiful trees are growing next to abundant grasses and flowers. There is water, and there are rock formations. All ecologies are represented in this one microecology without discrimination. It is a miniature, peaceful world. It is a beautiful living metaphor for what a new global ethic could bring.

Syria and drawing the web of tensions

Friday, September 9th, 2016

[ by Charles Cameron — with a Magnus Ranstorp squib in its tail ]

The issue is complexity, and how you represent it. The case in point is Syria.

Here’s a diagram that suggests complexity as a sort of crazy weaving, all straight lines and colors:

Daveed’s diagram has a network feel to it, with actord as nodes and the tensions between them as edges:

Karl Sharro’s tackling the wider context, but his illustration at least gives the sense of a ball of twine after a cat has carefully re-arranged it:

Juan Cole simply provides a screenshot from Google Maps —

jarabulus

— the headline America’s Syria SNAFU: Pentagon’s Militias fight Turkey & CIA’s Militias — which is effectively friendly fire framed as paradox — and some paras beneath it using words to describe the tangle:

The Turkish incursion into Syria at Jarabulus was advertised as an attack on a Daesh (ISIS, ISIL) stronghold and smuggling station in conjunction with (fundamentalist) remnants of the Free Syrian Army.

But the southern outskirts of Jarabulus had already fallen to the Pentagon-backed Syrian Democratic Forces, which are majority Kurdish but have a significant Arab component. The Arab, non-Kurdish SDF brigades such as the Seljuk brigade, the Army of Revolutionaries, and Northern Sun Brigade had fought to liberate the northern Syrian city of Manbij, due south of Jarabulus from Daesh. They have an outpost in the village of Amarna just a few miles south of Jarabulus, where they call themselves the Jarabulus Military Council.

The Turkish army, having secured Jarabulus itself with the help of fundamentalist militias, moved down to Amarna, where they met fierce resistance from the Syrian Democratic Forces, who are allied with the Kurds. The Turkish air force bombarded the SDF positions in Amarna and the militias responded by destroying two tanks and killing one Turkish soldier. Fighting continues there.

To be honest, I’m not sure which of those means of modeling a complex system leaves us best able to understand the situation on the ground.

Maybe this one’s the best:

Donald Trump and his Trumpalike, The Denald

Saturday, June 25th, 2016

[ by Charles Cameron — reality imitates parody, a subset of life imitates art ]
.

The Denald Trump account posted this fake trumpery as satire:

This tweet was quickly followed by an all-too-similar one from the real Donald:

— the only problem here being that the Scots voted to stay..

**

And now the coup de grace — Obama speechwriter Jon Favreau‘s eye catches the match between parody and reality in these two quotes — and tweets them in juxtaposition, DoubleTweet-style:

— with the added bonus of a playful sideswipe at the Bostrom / Musk simulation idea..

**

It seems there really were Scots shouting at Trump to leave — he’s not well-liked over there — so was he the one who was being ultimately playful and ironic — deliberately misunderstanding them for the purpose of his tweet?
