Oh, you're one those. You are the one who used the adjective
"aimless" which means without direction or purpose. You are
claiming that math has no purpose; I have you one example to

Regarding my comment - it shouldn't have been too difficult to

recognize
that people are metaphors for their professions, and the point of

the
analogy (silly or not) is that standing alone, mathematics is an

aimless
avocation, which gets its direction for the most part from science.

Math, by itself, may be aimless. However, it teaches people
how to think well. I don't call anything, that teaches people
how to use analytical thinking, aimless.


Aimless (lacking direction) isn't the same as pointless (of no value).


Any new thing is going to have the attribute of lacking direction.
It's only in hindsight that one can determine there was direction.

If you start labeling a discipline as aimless, the conclusion will
be to not teach it. You might try to view the relationships between
science and math as symbiotic rather than parasitic. Your comment
implies that math is parasitic to science. Neither would have
made published advances without the other.


I think you're still reading more into the word "aimless" than is

warranted
by its definition,


I am using the definition of aimless; you are ignoring half of the
definition of aimless. I am concluding that you are doing this
because you have an attitude problem and are trying to prove
you're right.

..and I don't want to get into a semantical argument.


You're going to have a semantical argument when you start
throwing words around that denote a negative connotation
but try to make the claim that you're not trying to denigrate
studying math.

.. The
fact is you can get a Shakespearean sonnet by setting enough monkeys at
typewriters for a long enough time,


No, you can't.

..but to produce one efficiently requires
having some idea of what it is you want to achieve (i.e. direction).
Mathematics (i.e. logical symbol manipulation) can't provide that
direction.



Since when is math a logic symbol manipulation? Computer programming
may be this, but math sure as hell isn't.

It sounds like you've only taken high school algebra and skipped
the plane geometry course.

That's kind of like asserting the superiority of automobile mechanics
over those who design and build the cars.


Most scientists need to understand math. The division that I'm
suggesting is more like the competent verses the incompetent.

Who do you think understands logic best, mathematicians or physicists?


That is a rather stupid question (and answer, since I'm sure you
intended it to be rhetorical). He who understands logic best is he who
understands logic best. I have a question that you should be able to
answer by pure logic. Do you think it's possible to drill a square hole
with a square bit?


Tom Roberts is a physicist who denies the logic of my opening post.
http://www.everythingimportant.org/v...hp?p=3437#3437
http://groups.google.com/groups?&sel...s13.hou.wt.net

Will Twentyman and Gene Ward Smith sound like extraordinarily
competent mathematicians. They agree with me.


So far, you have validated my hypothesis that you define competent
by the ease with which you can misconstrue the comments of someone
into agreement where there is none.

[...]
There really isn't any contest about who is right in elementary logic.
In this instance, mathematicians are preeminent over physicists.


Only if you are talking about the logic needed to be a mathematician.
Pn the other hand, if one is designing an experiment to measure parity
violation in nuclear scattering, only an idiot would consider the
mathematics department as the most obvious place to find the most
logical opinions on how to perform the experiment.

This is your condemnation:

Suppose you begin a derivation by assigning a clear and
undisputed physical meaning to real parameters x, x', T, T',
and a real constant u. From that reasonable starting point,
I claim it's legitimate to pick a real number 1/c and then
define a new quantity v by the equation u=v/sqrt(1 -v^2/c^2).
The point is to then write everything in the ensuing
derivation in terms of v and not u. I also believe it's
legitimate to define, without any justification whatsoever,
the function gamma(v) = 1/sqrt(1 - v^2/c^2).


There is no requirement to give a physical meaning to any of
the above, .... You've defined u as a function of v, for real
v with |v| c. You can certainly do that if you choose, ...

You are also free to define the function gamma, ... You might
also consider the transformation r = c arctanh(v/c), "rapidity",
which has nice additivity properties.

None of this is physics as yet;

the physicists find troubling. Suppose you begin a derivation by

It appears that you are making a definition. That's perfectly ok.
Next you have to defend any interpretations you may put on
that definition. I suspect they have an objections someplace
else.

As you say, you're absolutely certain that you're unaware of any
positive confirmations in my favor in the expert testimony of Gene
Ward Smith and Will Twentyman. I suppose that means that you
also don't recognize any difference between purely positive
confirmations if contrasted to the directly opposite, negative
denials by Tom Roberts.

Look again. Tom Roberts directly contradicts the answers given
by Gene Ward Smith and Will Twentyman in his wrangling with
me. Here is the pertinent exchange:

The quality of a derivation of the equations of SR is usually judged
by:
1. the simplicity and physical believability of its assumptions, or
lack thereof.


and:
2. the generality of those assumptions.


Your derivation is seriously lacking in both of those aspects:
1. On page 2 your assumptions for \mu and \gamma are completely
unsupported,


My official derivation begins on page 4. The assumption that you refer
to (page 2), the principle called change of variables, also called
substitution, is one of the clearest and most useful mathematical
ideas in high school algebra and baby calculus. What's your dispute
with intuitively simple fundamentals? What support do I need and
why is it an unwarranted physical assumption if I label the function
1/sqrt(1 -v^2/c^2) with the Greek letter gamma?

and are not obvious at all -- these are QUITE unusual assumptions,
to say the least; why should anybody believe them?


Why should anyone believe in the substitution v/c = tanh(theta),
which transforms the usual Lorentz transformation to its
hyperbolic form?


Because that is not an ASSUMPTION, it is a CONCLUSION.


There are plenty of derivations of the Lorentz Transformation
equations that don't define theta. Take Einstein's tortured derivation
for example (Dover, The Principle of Relativity). And try to find a
mathematician who isn't going to laugh at you. If theta isn't defined
anywhere in a derivation, then you are perfectly free to let theta be
anything that pleases you at any step in a derivation. And even if a
simple substitution/transformation doesn't please some physicists, it
still has every mathematical right to exist.

There is no physical assumption in the mathematical substitution
u=v/sqrt(1 -v^2/c^2).

mathematics.
