| Mar 1, 2015 at 1:32 | comment | added | Conifold | Thanks, but I seem to be confused. Wouldn't the probability that it will be in a lower entropy state at some other time also approach 1 by time symmetry, i.e. we should observe both. Does "ergodic hypothesis" follow from Hamiltonian equations? Also what does "look like" mean exactly in "the set of all microstates comprises microstates that look almost exactly like the maximum likelihood microstate and almost nothing else". | |

No, I really do mean 0.43: if you happenned to draw only 410000 red balls in a sample of $10^6$ where the actual proportion of red was 0.43, this would be a fantastically improbable event, and thus the probability that the next sample of $10^6$ balls would contain nearer to 43% red is extremely high. | |
