第三次投AJP。这次最惨，直接被编辑据稿。他觉得太数学，不够物理，不能引起广泛的兴趣。

跟料想的完全相反。本来以为庞加莱回归是具有广泛兴趣的议题。

Dear Prof. Zhang,

We have reviewed your submission, "Witnessing a Poincare recurrence with Mathematica," (our manuscript #29621) and determined that it is not appropriate for publication in the American Journal of Physics.  I have discussed your manuscript with a member of the Editorial Advisory Board and we are in agreement that this manuscript is more about mathematics than it is about physics, so it would not likely be of much interest to the broad readership of AJP.  In other words, AJP is really not the right venue for such a paper.

Please refer to the "Information for Contributors" and the "Statement of Editorial Policy" at the AJP home page http://ajp.dickinson.edu.

Therefore, I regret to inform you that we will not pursue the publication of your manuscript.

Sincerely,

*******
