Only two very short comments on your mail:.

Two MUCH shorter responses:


The following note is almost superfluous therefore.
1) I try to show, throughout numerical examples, that probability and statistics can be faced as an experimental science (let me say).
2) I check, every time I can do it, (always empirically) what is true and what is not about the *recipes* that the text books are full (example: the computer intensive methods).
3) My only *tool* is a home computer and my skills in programming are restricted to BASIC. It seems to be sufficient but is quite adequate to my goals: to justify what I achieve and allow the Readers to check its soundness.

I. Use your method to show us how you find the Expected Value of a
Standard Cauchy random variable X.

Remember the old * René*: I know that I know nothing.

II. That saying does NOT apply to you, Luis A. Afonso; but it TRUE of
you that you know nothing.
