Thank you very much, I appreciate that you followed my question to read this article.

I will have a deeper look on what you recommended to me, the work of Stephen Wolfram. It will take me some time. As I had many comments to answer today I feel that I am getting tired. I do want to give credit to your reply so I don't want to become hasty (which I deeply dislike).

Enjoy the rest of what's left of this day.
