Gents:

My 1st post ... FYI: retired PhD biophysics/polymer science.    Searching 
Web sources I have been unable to find a necessary & sufficient 
justification for the use of the QUANTUM MEASUREMENT concept.  
Objectifying/singularizing  measurement  seems tied to the strange QM 
identification of variables with  maths operators required (??) by  
uncertainty relations.  I do read the issue is still considered OPEN in 
the realm of QM foundations. So what happens if you reject (ignore etc.)  
the concept of measurement ( being a "thing")  as is done in classical 
physics ?

Well you get alternate ways of dealing with the collapse of the wave
function. Like Bohmian QM or Everett’s many-worlds hypothesis.

Do I need to read Diracs book to understand why Copenhagen-model 
requires .. or is expressed in-terms-of a "physical" measurement. My 
complaint is that the noun MEASUREMENT refers to a group of actions ... 
it's really a collective verb not a noun (object) and in being 
bastardized by QM has lost all physical meaning. Yes I kinda understand 
that "measurement" is supposed to throw a shadow of the (mystery) state-
vector onto the set of eigenvectors for that operator. I'm not claiming 
the math is bad ... I'm asking if it "means anything" beside giving 
correct predictions ... like a weegee-board.  I suspect the answer is 
NO .

All measurements of an atom involve a laboratory apparatus
with a second atom. It is not possible to complain loud
enough to make measurements seem unnecessary. The quantum
description of measurements is useful as a stepping stone
to a greater wisdom about reality.

You are telling me ... I think ... to read Diracs book. Because it is 
useful. Perhaps I will.  My question is ... does physics know it to be 
necessary ? Certainly no use is made of the QM measurement concept in the 
derivation or application of the Schrodinger Equation to the hydrogen 
atom.

You can read books other than Dirac. 
You speak about the "QM measurement concept" but you never
give details like : 

QM measurement concept using a gas
QM measurement concept using tungsten carbide
QM measurement concept using light
QM measurement concept with a scanning tunneling microscope
QM measurement concept with theory only using algebra

Alan: Yes my questions are incomplete and I am certainly struggling with 
the physics. FYI/// I find my self with a few weeks "downtime" and 
proposed to retry understanding some aspects of QM. Immediately I run 
into Heisenbergs definition of a QM variable as a maths operator ... & 
Diracs mathematical definition of a measurement. The justifications for 
both appear to be heuristic ... and thus why not some other physics to 
predict random beta-decay and hydrogen atom  discrete energy levels ? I 
am poking around  at fundamentals trying not to appear too stupid .. or 
too gullible.

If you are asking if math is more real than reality (which is a very 
popular view at present) the answer indeed is no.

But if he is asking

"Is a crazy theory with correct predictions better 
than a logical and understandable theory with wrong  predictions ?",

then the answer  indeed is yes.

Craziness of theories must match craziness of  observable reality.

It applies to QM and SR alone, as well as to both combined.

Which is correct. Which means when the assumptions of your math do not 
match the observations of reality, you need a new math, not some fantasy 
to explain your mathematical reality.

Learn to read properly, 
an advice you often provide to others.

There is no my math nor my mathematical reality.

There are tons of  experimental evidence from nuclear physics to
 relativistic quantum chemistry.

Good advice for everyone.

> There is no my math nor my mathematical reality.

You misinterpret. I do not mean "your math" as in your personal 
mathematics, but "your math" referring to one considering the 
traditional theories of physical science.

Point is simple. If your measurements (reality) does not agree with your 
theories (math) then the theories are wrong.

If your measurements do not agree with the basic assumptions of one's 
(OK?) math then One's (OK?) math is wrong and one needs a new kind of 
math with different assumptions.

> There are tons of  experimental evidence from nuclear physics to
>   relativistic quantum chemistry.

Lots of measurements are good, but that only makes theories correct if 
it agrees with theory.

Benji: We are conflicting ... and I will try I explain the conflict. I am 
willing ( trying ) to reject the word/concept measurement as a single 
physical object. You can say lots about a measurement, but there is no 
number or function that maps to a measurement; it's a complex bit of non-
linear stuff.  It's a process with no single/unique/concrete outcome.  
Just think of all the parts to a light-scattering machine. The only true  
physical objects are such entities as mass, speed,  time(?) ... and 
product quantities like Youngs Modulus, momentum  temperature etcetc ... 
we extract these physical values from an experiment ( non object ) by use 
of POINTERS & digit-readouts & a few  other exotics perhaps. This is the 
POV of classical physics, where we say "I have measured an electrons 
magnetic moment using a solenoid ..." or whatever. The pointer output of 
a measurement maps onto an external reality ... which I believe 
Copenhagen rejects for QM analysis. So again my question ... as you say 
BOHM and MANY WORLDS hold to a realist physics: is it possible otherwise 
to have both QM and realistic physics W/O the measurement concept ?  Or 
am I mixing up something basic and spewing nonsense ?

There is becoming a new understanding of measurement that
I saw recently. I will try to find the link to the article,
but the basic point seemed to be that there is nothing special
about a measurement.

What does a measurement boil down to?
A photon striking an electron
Basically any fundamental particle interacting with another.

Because of this, Schrodinger's cat thought experiment is
no longer a paradox of superpositions dead and alive.
We cannot truly isolate the cat from the rest of the universe.
There are quantum interactions (measurements) continually
happening.

I don't know if that helps. I must admit I don't understand
it. And I think many do not understand this.

The only other thing I could suggest is to post in the
sci.physics.research group. That one is moderated, so
much less noise and much more thoughtful and experienced
posters who can respond.

I have read-of this new interpretation ... constant interactions == 
constant measurement == semi-classical world since ( supposedly ) all 
wave-functions are constantly being collapsed out of every quantum-like 
flakey super-position.  This "water-bath" model of reality is favored by 
Arnold Neumaier: http://lanl.arxiv.org/pdf/0810.1019v2 ... I find his 
physics really really hard to grasp.

Nonsense, Jeff. Cause and effect is fully supported in QM. I think you’re

No, it's SemiRandom, like a poker game... place your bets.

_Everyone_ is enslaved, there is no free will.

One may have a preference but even if it is predetermined you don't have 
to follow it.
