Dear Stephen,

276] [Fwd: Fisher information]

*> Dear Stephen,
*

*>
*

*> I got the book of Frieden. It is interesting. I now begin changing my
*

*> reservation I wrote in the following quotation.
*

*>
*

*> He discusses the error which necessarily arises in the closed
*

*> observations (errors are associated with any closed observation: if the
*

*> observation can be considered open as in Peter's paper, the error does
*

*> not exist), and as a minimizing solution of the error,
*

This is my misunderstanding: Frieden obtains Lagrangian by minmizing the

Fisher information I, which decreases, as time goes to infinity, to a

minimum that is an equivalent of an equilibrium. This, by Cramer-Rao

inequality

e^2 I >= 1,

means that the minimum of the error e becomes the largest. His equilibrium

corresponds to the state with maximum entropy.

Best,

Hitoshi

he derives

*> physics laws in the form of Lagrangians for each specific physical
*

*> observation. Thus errors are the cause of physics in his context.
*

*>
*

*> In the context of Local Systems theory, this each Lagrangian seems to
*

*> correspond to a factor in the factorization of the universe, e.g. in the
*

*> factorization X x R^6, the first factor corresponds to GR and the second
*

*> to QM. Maybe my method would give a unification of all kinds of
*

*> observation. Here I mean by observation, GR, QM, Electromagnetism, QED,
*

*> ... So the universe is a tensor product of infinite number of factors,
*

*> each factor of which corresponds to each theory. The unification would
*

*> be given as a reconciliation by means of some translation among theories
*

*> that makes them commensurable with each other (as the relativistic
*

*> "correction" of QM values gives the relativistic QM results).
*

*>
*

*> The book seems well written, although I am still at the second chapter.
*

*> Hillman's critiques you posted in [time 314] might apply to the
*

*> differential geometry part (I do not reach that part). But the
*

*> philosophy of the book is clear. The ambiguity which I felt when reading
*

*> the advertisement is not in the book.
*

*>
*

*> Best wishes,
*

*> Hitoshi
