RE: Roy Frieden
I got Roy Frieden's book, on the use of Fisher Information to derive some physical laws. Damned ! It is not easy. In particular Frieden is not clear on his philosophical and physical assumptions. It will take some time before I can conclude if his approach is relevant for "our concern". My intuitive brain (or my little finger, if you prefer) tells me that there is something appealing there ... My analytical brain tells me to revise Statistics and Variation Calculus ... I have find some commentaries on that question in: http://members.home.net/stephenk1/Outlaw/FisherInfo.txt Affaire a suivre ... Bruno.

Frieden approach seems almost to "beautiful" to be true. I order Roy Frieden's book "Physics from Fisher Information", 1999, Cambridge University Press. I am impatient (and a little skeptical) to see how he "derives" Schroedinger equation and Wheeler-deWitt equation. Bruno PLEASE, NOTE THE CHANGE IN MY URL (The ~) !
