- Simulation of a Maxwell Demon
- __________________________________
-
- The Maxwell demon (a color separator one) is sitting in the
- hole of the wall which separates the the container into two parts.
- She lets the green particles pass only to the right and the red ones
- to the left direction. The upper diagram shows the entropy of mixing
- of the system, the lower one shows the horizontal density
- distribution of the green particles. The green particles start from
- the left part of the container while the red ones from the right
- part.
-
- Watch the strange operation of the Maxwell demon:
-
- The particles first uniformly fill both sides of the vessel
- then the demon slowly pumps the green ones to the right side, the red
- ones to the left side. The entropy of mixing quickly reaches its
- maximum then slowly decreases to zero again.

- Control keys:
-
- <F2> : switch ON/OFF tracing of a randomly selected GREEN particle
- <F3> : switch ON/OFF tracing of a randomly selected RED particle
- <F4> : switch ON/OFF shot noise
- <F5> : switch ON/OFF mutual collisions of the particles
- <P> : temporarily suspend the simulation, resume it by pressing
- any key
- <Esc>: stop the simulation
