Multiple runs

Fluctuations are substantial, so every run is different. The cyan curve in the previous pages (reproduced below) is a little atypical, in that the whole 16kT of work was done unusually fast. (It was the first one I ran, honest! I wasn't trying to misrepresent!)

The figure below makes clear that nearly all the work done is done in a brief big push as the piston location changes from essentially zero to about 1. The subsequent wandering of the piston from 1 to 40 generates far less work. The last 2kT or so of work is rather reversible, it comes and goes.


The upper graphs show the total potential energy of the system (including the two particles riding up against the springy walls and the piston, as well as the 1-6 potential and the linear potential).
