the derivation of the isobaric ensemble is mathematically WRONG!!! 134.93.131.17 15:00, 6 November 2009

- Could you provide details? --

- The book by Ziman is quite readable, but please consider the following references:
- A. Drory "Exact solution of a one-dimensional continuum percolation model", arXiv:cond-mat/9610062 8 Oct (1996)

## Entropy of 1-dimensional hard rods[edit]

Hi, Very nice wiki. I have a question: What is the entropy of 1-dimensional hard rods gas?

Thanks

- It may be worthwhile taking a look at the article Paolo V. Giaquinta "Entropy and Ordering of Hard Rods in One Dimension", Entropy
**10**pp. 248-260 (2008).*Entropy*is an Open Access journal, so you should be able to download the article free of charge. I hope this helps. All the best --**Carl McBride**(talk) 16:01, 14 December 2009 (CET)
