String Theory and Letterman |
Brian Green was on Dave Letterman last night discussing his new book on
string theory. Said this would tie quantum mech to relativity--and
answer many questions. Letterman asked "And what will this do for
me--how will it make my life better? ;-))

It would be illuminating to the young people,
if Letterman had a few GTR cultists on his show,
and asked them the same question.
As can be seen,
GTR is a Tower of Babel
that generates more heat than light,
and wastes time, money and minds,
on pursuits such as time travel, worm holes,
warped space, dragging space around,
black holes, gravity waves, etc.
A mind is a terrible thing to waste.

To some degree, this can be said about everyone from one end of the
educational strectrum to the other. Every group of "hardwired" thinkers
has their pursuits and a belief system that makes perfect sense to
them. Artists each, trying to teach others to paint with their
colors--but thats ok. That's what makes America great--and others "head
whacking" thugs.
A mind is a terrible thing to waste.
But it may only be wasting in your "reference frame"--naz gimme da
cheeeze!

You may be right cnctutwiler.
If some guy consumes thousands of hours,
and tens of thousands of dollars, studying GTR,
and then his mom and dad and the taxpayers say:
"Johnny, it's time you went out and
paid for your own way.",
he was wasting his mind,
but if mom and dad and the taxpayers
never told him that,
he was wasting time, money and minds
in another "reference frame".
"Nice work if you can get it!"
As for me,
I am tired of wasting my time, money and mind
supporting Johnny.

It will lead to a "theory of every thing". You will have a better life if
you have only one good theory rather than many wrong theories.

How about a few good, useable, viable, cost-effective, models,
that can be used by practical people to do real world things,
rather than an esoteric model that only can be used by
a few impractical people to talk about to
practical people?
What I'm waiting for
is to see some of the GTR gang
( And the high energy gang.)
use their powerful esoteric knowledge
to make a lot of money in the free market,
like the people privy to electronics, Q.M.,
hydraulics, genetics, and materials, knowledge do.

There's nothing wrong with preferring engineering to fundamental
physics, if that's what floats your boat. But keep in mind that most
electronic engineers and optical engineers and material scientists
would not be doing what they are doing if quantum mechanics hadn't been
figured during the last century -- despite their being no predictable
practical value to the work at the time.
Keep your eye out on quantum dots, attosecond laser pulses, and quantum
computers over the next two decades, and THEN tell me that fundamental
physics is worthless.

PD raises a good point.
The high end physics people
in quantum mechanics, thermodynamics, electronics,
"provide others with the necessary tools",
to do a better job.
Perhaps someone will list some of the viable, cost-effective "tools"
that the "high end <GTR> physics people"
have provided for the grunts to use,
and post references to actual real world applications,
which PROVE, rather than assert,
that the tools were ACTUALLY used.
It appears to me that several branches of
"high end physics", like GTR, are Towers of Babel,
that piggy back on the successes of other "high end physics", like Q.M.
and that these schools waste enormous amounts of time,
money and minds on pursuits that cannot be anywhere near
justified on the basis of a discounted rate of return.
As David Letterman so aptly put it:
"And what will this do for me--how will it make my life better?"
( Based on the time, money and minds spent on the effort.)
A mind is a terrible thing to waste.

Tom--you make some thought provoking points--and some that are just
provoking. My objective here is not to sell ideas to the House and
Senate Appropiations Committees--I was simply asking for inputs to a
simple question. Also, I like cheeze--it's a good thing and I support
helping the disadvantaged. My problem is in a democratic system the
majority party can look at old Tom and say--I think Tom has to
much--let's take what he has and give to "xyz"--and if "xyz" votes for
us--yummy. Some call it democracy, I call it legislative thieft. When
your compassion moves you to help others with your own funds--then
you've got something.

I recall a little story about Gladstone (who was then the British PM)
visiting Faraday's lab. After asking many questions and showing great
interest Gladstone finally said "That's fascinating, but what it is
good for?". "I don't know, at the moment" answered Faraday, "but I'm
sure that one day Her Majesty's government will be taxing it".

Mati, how many centuries
do you think it will be before
Her Majesty's government will be able to recoup
the money spent on GTR?
I suggest that GTR is a Tower of Babel,
and consumes vast amounts of Her Majesty's government money,
and the time and minds of Her Majesty's subjects.
Her Majesty's government money
is a terrible thing to waste.

Why is it a "blessing"

Hopefully Sam Wormley
will post specific points that
it will be a "blessing"
for readers of my posts to miss.
Tom, your postings are insignificant. You're just a cranky old troll.

I am pleased to see that Sam Wormley
has looked into the mirror,
and seen a reflection of himself.
Hopefully he will reflect on what he saw,
and will commit himself to becoming
a decent human being,
and accept the fact that he is not
privy to powerful, esoteric information,
and that he attacks folks because
he is cranky, old and insignificant.

It is interesting to observe how threads degenerate.
I suggest that true seekers of wisdom and truth
can learn a lot by analyzing this pattern.
Note that dichotomies decay exponentially
( A damped oscillation.) and eventually assume
a relatively stable back and forth, action/reaction cycle.
( Insult/counter-insult)
One could infer that systems degenerate to
the lowest level that can be sustained by the degenerate partner
to an cyclical interaction.
In other words exponential probing extends to a
finer and finer level, until the limit of
the degenerate partner is reached, at which point the cycle
becomes a simple, repeating back and forth pattern.
This also suggests that the best way to solve problems,
is to have competing sides engage in dichotomies,
and when the pattern degenerates into a cycle,
to substitute new blood for the degenerate component,
which reached the limits of its' ability.

Tom--could you solve this physics problem for me? Thanks!
A spring and piston compresses air in a small cyclinder.
Compressed air exits cyclinder through small hole
and accelerates 9.2 grain projectile to 900fps
(7.9 grain 1100fps.)
The high pressure gas exit hole has no porting/radiusing/
coning/smoothing/convergence/d=ADivergence etc on either the
high or low pressure side?
Question: If the high pressure side of the exit hole had
some radius of curvature--would projectiles
delta V be significant? i.e. 5-10% or more
What would that radius of curvature be?
Compression cyclinder 1" dia--exit hole .177" dia.

It is interesting to see that Sam Wormley,
who never addresses the gestalt of a message,
but lies, posts phony references, and attacks the messenger,
criticizes me for not wasting my time to do someone's homework.
Why don't you solve the problem Sam,
and show the sci.physics readers
just how smart you are??????
And after you solve this problem,
I'll post a few that deal with issues that you promote,
and claim to be an expert in.

Tom--does a solution require money to solve or just a sharp pencil and
some paper? Your recent post (to develop equipment to measure surface
irregularities) that I helped you with did require some specialized
equipment and generated my comment--"how much money do you have to
spend to solve this problem." As I remember, I provided one cheap and
one expensive solution. Can you provide some input on this compressible
flow problem--this is not a test--acceptable answers include--no or
yes, with accompanying discussion.=20
Thanks

Previously I posted:
"I would appreciate any input and ideas about
producing an audio signal that models a surface,
in a small portable, inexpensive package.
A small, low-power, laser probe would do a better job,
but I am hopeful of using an MP3 player/recorder for this,
as the cost, size, power consumption and frequency response
seems to be ideal.
I have a number of time series analyzer programs that
I have experimented with, but would also appreciate
any suggestions along these line."
It seems to me that it was pretty clear that I was interested
in recording an audio signal that replicated a surface
into an ordinary MP3 player/recorder,
and then playing back the data into a standard PC
for analysis.
I suggest that your "help"
which is posted below,
was a childish, useless, cheap-shot,
rather than anything useful.
regarding you problem,
if you post drawings that accurately depict your
situation, with all of the pertinent physical
and environmental data,
I'll try to help you.
Post the data on a web site,
and post the address of the web site
in this news group.
If the problem looks like it will take
a lot of time and effort,
I'll quote you a figure for consultation.
--------------------------------
Use a phono cartridge with O scope--dVolt ~ dy--some integration over
dt and correlation with linear distance required--but your website
suggests you can handle the politics.... sorry, I mean math. (Portable
scopes available for less than $200--but being a science guy, you
probably have one. ;-)

You're correct Tom, that posting was bordering on a "cheap" shot, my
appologies. I had just gone to your website and my anti-virus software
went on red alert--that didn't put me in the best frame of mind.
Actually though, the phono cartridge was a pretty good cheap solution
if you had an O scope. Was Sam Goldwasser able to provide you any help
with the modulated laser idea?

I don't understand why your
"anti-virus software went on red alert"
as to my knowledge there are no
scripts or activex routines on my site.
Please post what happened,
and I will contract the server people,
and see what they think happened.
I got a couple of more civil, more real world, replies
in the newsgroup that you suggested,
but nothing I can use.

He's just frustrated 'cause he can't babble ***** to potential buyers
anymore.
Maybe if he looked around there might be a used car lot that could use
his "talents".
