# s-phys: if you take a large collection of chaotic balls ...

<< If  you  take  a  large  collection  of  balls  in  contact  and  force  some  of  them  to  spin,  they  can  behave  like a  set  of  gears,  with  each  ball  rotating  without  slipping.  Experiments  and  theory  show  that  this synchronized  motion  can  be predicted  even  when the initial  motion  involves  seemingly  random slipping  between  the  spheres  (like  the  skipping  of  gears).  The  researchers  say  that  the  ability  to predict  this  collective  motion  could  lead  to  three-dimensional  gear  systems  in  which  manipulations of  one or two spheres allows complete control  of  the  rotational  motion  of  the  others >>

# s-behav: the intriguing behavior of the elderly Barbary macaques.

<< With  increasing  age,  the  monkeys [Barbary macaques (Macaca sylvanus)] became  more  selective  in  their  social  interactions,"  Almeling  says. "They  had  fewer  'friends'  and  invested  less  in  social  interactions.  Interestingly,  however,  they  were  still interested  in  what  was  going  on  in  their  social  world." >>

<< Why  many  major  strike-slip  faults  known  to  have  had  large  earthquakes  are  silent  in  the interseismic  period  is  a  long-standing  enigma.  One  would  expect  small  earthquakes  to  occur  at least  at  the  bottom  of  the  seismogenic  zone,  where  deeper  aseismic  deformation  concentrates loading.  [AA]  suggest  that  the  absence  of  such  concentrated  microseismicity  indicates  deep rupture  past  the  seismogenic  zone  in  previous  large  earthquakes >>

# s-gst-game: tit-for-tat and the emergence of morality

<< Ultimately, the results showed that the best strategy was 'tit for tat' – which means that a player starts out cooperating on the first move, and then does whatever it's opponent does >>

<< it's interesting that it emerged – it self-organised – into this state of being that the Old Testament morality ended up winning in this environment >>

<< So in fact what was found in later studies, when they examined prisoner's dilemma in environments where errors occurred with a certain frequency, is that the population tended to evolve to more generous, more like New Testament strategies that will 'turn the other cheek' >>

<< If natural selection leads to morality, that's pretty interesting. And that came from maths! >>.  Steven  Strogatz.

Steven  Strogatz, in: Elena  Holodny. The  mathematical  origins  of  morals.  Business  Insider, 14  Jun  2016

FonT: <<  and then does whatever it's opponent does >> ... approccio senz'altro utile all'interno di scenari di simulazione; in contesti reali un approccio creativo, esplorativo, perturbativo, e per mia opinione anche funzionale, al problema di  decidere sul comportamento cooperativo al successivo "run" e' quello di affidarsi all'esito del lancio di moneta, ovviamente dopo un giudizio (formato da componenti di natura analitica ma anche soggettiva) circa il contesto che ha fatto intravedere la necessita' - per l'attore cooperativo - di una biforcazione, di operare una scelta.

Percio' "tit-for-tat generoso quasistocastico", tutte le volte che un gambler decide di iniziare/ sostenere un gioco "al buio", anche quando sa, oppure sospetta, che il gioco e' "a priori" fondamentalmente truccato, vale a dire deviante dai due vincoli del gioco legale, naturale [1,2,3]

Nelle componenti  "eye for an eye" vs "turn the other cheek" o, se si vuole piu' in generale, nei livelli di "risveglio" in senso buddista degli attori partecipanti tit-for-tat, dipende, anche a breve/ medio termine, la velocita' evolutiva degli esiti del gioco, esiti che riverberano in ambito sociale, anche all'interno di contesti "altri".
