Calculating it from agents would probably get you near zero probability. I look at it in the paper (via the fluctuation theorem).Jason Smithhttps://www.blogger.com/profile/12680061127040420047noreply@blogger.comtag:blogger.com,1999:blog-6837159629100463303.post-12682585601742260032016-03-14T12:11:42.287-07:002016-03-14T12:11:42.287-07:00Lol...

They covered complexity arising from an entropy gradient, Boltzmann's explanation of entropy, Shannon's definition of information and Maxwell and his demon.<br /><br />I wonder if you can calculate a "behavioural factor" based on the probability of a system with O(1e9) agents experiencing a significant spontaneous decrease in entropy vs the frequency that actually takes place in real life? They mentioned in the documentary that Boltzmann, responding to critics, calculated an expected time it would take a half cubic centimeter container of gas to return to its initial condition given you allowed it to expand into a full cubic centimeter at t=0. They didn't say what that time was, but implied it was clear even at the time that it was much longer than the solar system could be expected to last.Tom Brownhttp://www.google.comnoreply@blogger.comtag:blogger.com,1999:blog-6837159629100463303.post-57353518877338014852016-03-14T11:19:58.581-07:002016-03-14T11:19:58.581-07:00It was my one of my retro-iPads.

And for that example can you point out what is:<br /><br />1. The framework<br />2. The "prior art"<br />3. The "empirical successes" explained by the prior art<br />4. How this prior art explained it<br />5. In what sense it is "captured" by the framework<br /><br />?<br /><br />I can think of one but I may be wrong since I don't know much about these subjects ... But I just watched a documentary on Boltzmann.<br /><br />So statistical mechanics = framework.<br />Thermodynamics = prior art.<br />Ideal gas law an example of an empirical success.<br />SM captures it in the sense of explaining what entropy is and why it behaves the way it does.<br /><br />How's that? <br /><br />What I mean by "dumbed down" is something more accessible.<br />Tom Brownhttp://www.google.comnoreply@blogger.com
