Comment on ``Experimental Demonstration of Violations of the Second Law of Thermodynamicsfor Small Systems and Short Time Scales''

Published 2002-08-08, updated 2002-09-15Version 2

The experimental verification of the fluctuation theorem by Wang et al. is explained in terms of a simple Langevin dynamics. This implies that the entropy consuming trajectories found by Wang et al. are fluctuations generated by a random force and do not violate the second law.
