Salutations to all wikipedians,

I'm a new editor here, and so far I have been active mostly in statistics and statistical mechanics.

Here are those articles to which I contributed significantly.

Also, I can write French and English. In french I have created this article:

fr:Loi de Student

And also translated a bit here, a bit there from time to time.

-In the foreseeable future, these are the articles I will put some amount of work on:
-* [[ideal chain]]: thermodynamics of the ideal chain. Generality of the model must be more carefully explained.
-* [[degrees of freedom (physics and chemistry)]]. Degrees of freedom have to be defined. This is linked to the scalars describing a micro-state: each particle has 6 of them: 3 positions, 3 [[momentum]]s. [[statistical independence|Independent]] and '''quadratic''' degrees of freedom also must be defined rigorously. Finally, the equipartition theorem must be resrained to the '''classical limit''' of [[statistical mechanics]], and to the case of [[statistical independence|Independent]] and '''quadratic''' degrees of freedom.
-* [[entropy]]: must be defined in general. Current definition is only relevant to a particular case, and apparently does not mention it.
-* [[heat equation]] this article will be reorganised, and maybe cut in two articles. This makes debate...
-* [[Langevin equation]] characteristic timescale must be introduced. Link to a diffusion coefficient (similar to what I did when extractaing the diffusion coefficient corresponding to a [[random walk]])
-* [[Thermodynamics equations]]: must be expanded, applicability of the formulas must be explained. Formulas must be added.
-* [[critical point]]: Loads of things to say about this. Among other, introduce universality class and relate them to [[path integral]]s. Speak of fluctuations near the critical point. Illustrate the universality with simple comparison between ferromagnetism and liquid-gas equilibrium near the critical point
-* [[Chi-square distribution]]: application to determination of the confidence intervals associated to the [[variance]] of a [[normal distribution|normal]] variable of unknown [[mean]].
-* [[Van der Waals equation|Van der Waals gas]]: important for liquid mixes, and thus for polymers
-* [[Central Limit Theorem]]: add multidimensional version of the theorem
-* [[Casimir effect]] is not only a quantum thing, there's also a statistical Casimir effect (and I'd say it plays a bigger role inour lives)
-* [[polymer physics]]: surely some good history to be done. Good illustrations of the relations beween [[thermodynamic]] and [[statistical mechanics]]
-For topics below, an article is lacking (to my knowledge)
-* microscopic definitions of [[heat]] and [[work]]: I can't believe is, but apparently THIS is lacking.
-* liquid mixes: important by itself and for polymer models
-* short-range vs long-range ineractions: VERY important. Relates to polymers, and [[thermodynamics]] in general. Only if interactions are short-range does [[internal energy]] become [[extensive quantity|extensive]] in the [[thermodynamic limit]]. Only for short-range interactions can you introduce a surface tension that leads to [[capillarity]] effects. For example [[electrostatic]] interactions are long range. [[Van der Waals force]]-based interactions are short range.
-* further polymer models. I'm going to introduce models that have ineteractions between monomers. But this depends on many other things on my list... This means that when I'll have been able to do this, the domain of [[statistical mechanics]] at wiki will actually have reached a very satisfactorly level of developpement.
