@dcm@social.sunet.se @dcm@bookwyrm.social @NicoleCRust @dsmith @uh they do, but the thing that’s at issue is why they are suddenly all connected. What ‘caused’ that?

@UlrikeHahn @dcm@bookwyrm.social @NicoleCRust @dsmith @uh I looked for videos of this experiment to try and understand it better, but I don't seem to have found one.
I would think that the idea would be that what causes that is just the ensemble of causal relations between the buttons: weight, friction, etc with just the right values to make that happen. But my grasp of the case is not great, so I'm not sure.

@dcm@social.sunet.se @dcm@bookwyrm.social @NicoleCRust @dsmith @uh it’s just a thought experiment, Dimitri. You could replace it with anything that can be described with a network: say a bunch of new people move into a neighbourhood, they bump into each other randomly, two at a time, and become acquainted. When they meet an acquaintance, they pass on new information about the neighbourhood. At some point, when enough of them have become acquainted (ie formed pairwise ties) info will spread to everyone

@UlrikeHahn @dcm@bookwyrm.social @NicoleCRust @dsmith @uh ah, the description on the book seemed to suggest it was an actual experiment/demonstration, since it talks about connecting physical elements to each other and then mentions, implying a partial contrast, results from a simulation of the scenario.
But in the neighbourhood case, what is the puzzle? Information spreads by people meeting each other, right?

@dcm@social.sunet.se @dcm@bookwyrm.social @NicoleCRust @dsmith @uh

yes, but the contrast is between the case where information spreads to everyone. (network is connected) and where it does not (network is not connected).

This is where the phase transition as a function of number of pairwise links comes in…

@UlrikeHahn @dcm@bookwyrm.social @NicoleCRust @dsmith @uh urgh, this is annoying, for some reason I didn't see those earlier posts!
