# About Entropy Dependence on Observer

@article{Rumanov2004AboutED, title={About Entropy Dependence on Observer}, author={Igor Rumanov}, journal={arXiv: High Energy Physics - Theory}, year={2004} }

It is shown that the entropy of systems with large number of degrees of freedom is practically independent of observers, contrary to the claim of hep-th/0310022.
