More likely that the mortgagee foreclosed on us. Anyway, that seems
to be something like how the story ends in various religions.

Who is the mortgagee, and who the mortgage holder?

Folks,

Greed-addled shoppers crushed to death a temporary worker who was
trying to open the doors for Black Friday sales.

http://budurl.com/jezv

Fscking people:

      Kimberly Cribbs, who witnessed the stampede, said shoppers were
      acting like "savages."

      "When they were saying they had to leave, that an employee got
      killed, people were yelling 'I've been on line since yesterday
      morning,'" she said. "They kept shopping."

Some on this list have opined that religion is a great poison that
kills. I believe that a good deal of the damage done in the _name_ of
religion is, in fact, done in the name of greed.

Recently some physicists announced the result of some serious number
crunching that is evidence that the majority of the universes mass is
the interaction between quarks that form protons and neutrons.

Made of gluons that transmit the strong nuclear force this interaction
is the 'quantum foam' of bubbling particles popping in and out of
existence - in theory.

I don't like that theory. Not that I'm even remotely qualified to have
much of an opinion. I find the concept of particles popping in and out
of existence unsatisfying and inelegant. I would only accept it
as true if it's merely a way of expressing something deeper (m-branes
bending in and out of our dimension for instance).

I'd be much happier if the explanation was about more about the shaping
of space than the exchange of particles.

Here's a page summarising the news...

There is another metaphor from fiction that would seem to apply,
   from the Douglas Adams series The Hitchiker’s Guide to the Galaxy.”
   In book #3 (I think), our heroes find themselves on the “C Ark”
   from Golgafrincham, carrying the entire planet’s supply of
   “middle-men, managers, account executives and factotums”
   who had been tricked aboard and sent away by the two-thirds
   of the home population, who, thereupon, ended their long dark
   era and entered a golden age.

It's from Book #2 of the Trilogy (of five books), it's the "Ship B",
and the biggest error of the Golgafrinchans was that they included
in the "Ship B" the telephone cleaners - they civilization was wiped
out by a bug that lived in telephone dirt.

Yeah.  With some of the religious figures in the US, I think they've
forgotten what Jesus said about not being able to serve two masters, and
they're actually serving mammon.  And fleecing their followers to do so,
and telling them that if they only believe, they'll have great riches on
Earth.  Kinda contradicts the whole "lay up for yourselves treasures in
heaven" thing, all around.

(Matthew chapter 6 contradicts a lot of things that people are doing
*supposedly* in the name of Jesus.)

To answer the question about the story or about gods or about mortgagee
who is the mortgagee? Now that is a question about Gods and Dogs
The same word you see because we come from beyond the sun
After our planet blew up in this same galaxy beyond the dog star
And rode the debris like it was a space ship to earth and found these
Cave dwellers Knee Ander Thralls if you will Ice me doing they thang
As we dance and sing and built the great Helios pads mapping stars
Trying to get home and mocking our pass and travels to this terror
Affirma and so it is and so it shall be we are the extra terror arresta
We built the great Peril Amid the unicorn Ah Hiss that dance like
Snakes in the cutie and map the mirrors of the sky and invented
The greater calendars of the MY Ions and eons and so we are the creators
Of worlds before this world and we rose from our rocks and come
To the new beginning where the light travel with the lesser speed than me
And they come to envy us and wish to belong to us and become our
Domesticates so they mortgage they souls for the gold and silver stuff
Which were the remnants of our world and this is how it was to be
We confounded they tongues and created another language for them
And enslaved them to our epic oracles and so it was and so it is
That they stole our ideas as we evolved from their dead planet
To compete with their virus and our germ the sperm made
The journey from the hot rocks now cold and in their water
We found our first home and paid our first mortgages and so
It was and yet shall it be that one come out to evolve from gods to men

If the store were open 24/7, then there could be no door-opening stampede.

Well, that's not really  news, right?  We've known ever since the quark
theory was well established (with the November 1974 revolution in particle
physics), that the pion was a quark-antiquark pair (ups and downs) with a
mass of 140 Mev, while the proton and neutron had 3 quarks (ups and downs)
and a mass close to 940 Mev.

Made of gluons that transmit the strong nuclear force this interaction
is the 'quantum foam' of bubbling particles popping in and out of
existence - in theory.

So, I take it you don't even like QED, which has been verified to a zillion
places, because the polarization of the vacume and renormalization?  It's
been around for 50-60 years.  Indeed, virtual particles are so inherent in
quantum theory, I can't think of how to explain the last 80 years of
physics without them.  Maybe Rich knows of such a theory, but I know how
Weinberg talked about the fact that while one can come up with different
theories slighly different than special and general relativity that are
close to right, that one cannot do the same with QM.

You need to remember that the only purpose of physics is to model
observations. Discussion what is real and what isn't is metaphysics.  Thus,
the arguements over the interpretation of QM are metaphysical arguements.

It's unfortunate that the New Scientist tend to tack on its metaphysical
interpretation onto pretty good science when it reports on new physics.
Perhaps that's the only way to grab laymen, I don't know.

As I mentioned in my last post, this idea in QCD dates back to when I was a
grad student.  The work that was described was pretty good stuff, so I'm
not insulting the physicist.  But, the energy involved in the interaction
between quarks must be mass, so there is nothing earth shattering here.

But, like doing a QED calculation of, say water, and coming up with what is
observed, this massive computational work is well worth doing, and the
first ones to get it done deserve acclaim for getting it done.

At the risk of re-igniting a certain discussion... here's a great column, I
think, by Paul Krugman, about the current economic situation.

http://www.nybooks.com/articles/22151

The most relevant bit:

*How did this second great colossal muddle arise? In the aftermath of the
Great Depression, we redesigned the machine so that we did* understand it,
well enough at any rate to avoid big disasters. Banks, the piece of the
system that malfunctioned so badly in the 1930s, were placed under tight
regulation and supported by a strong safety net. Meanwhile, international
movements of capital, which played a disruptive role in the 1930s, were also
limited. The financial system became a little boring but much safer.

*Then things got interesting and dangerous again. Growing international
capital flows set the stage for devastating currency crises in the 1990s and
for a globalized financial crisis in 2008. The growth of the shadow banking
system, without any corresponding extension of regulation, set the stage for
latter-day bank runs on a massive scale. These runs involved frantic mouse
clicks rather than frantic mobs outside locked bank doors, but they were no
less devastating.*
I'll add one thought that keeps coming to me.  If free markets reliably
regulate prices, how the heck did we have such a crazy spike in oil prices
recently?  Surely neither supply nor demand changed much in such a short
time.  And I haven't seen anybody argue that any sort of government
intervention was responsible.  I suspect that what we've seen in oil,
housing and other bubbles is that we have created a system that amplifies
fear and greed.

Agree with what you are trying to say.
I think that as a magazine, NS is trying to engage lay folk and other
scientists whose expertise doesn't extend very far into QM. For most of us
the metaphysics *is* the important aspect of QM.
It helps us to work out the nature of reality and what it means to exist.

For we, the dummies<G>, it is difficult to hold on to the ideas of
simultaneous existing/non-existing, objects frothing out of nothing, or
matter mostly being not there in any sense that doesn't stagger one's common
sense and bring it to it's knees whimpering and moaning. QM is destructive
to much of the "rules" one has ingrained as soon as one learns to walk, it
just seems to go against all that one sees in day to day life.

The "rules" are of course, oversimplifications based on limited observation
from a limited viewpoint, but for those of us who lack the time to learn the
maths and pour over the datas, the metaphysics are all we have to hold on
to.
We can understand philosophy much easier than maths, they are easier for us
to discuss and digest.

I would hold that to be self-evident and supported by market behavior over

Had this argument with someone who was pretending to understand MWI
vs. Copenhagen the other day.

"The universe is quantum, it only looks classical on our scale" was
lost on her.  :p

(Although to be fair, classical mechanics does sum up pretty well what
we see on our scale.  It's just right for the wrong reasons, is all. :)

I can't believe nobody mentioned Stephen Baxter's book (he is one of the Bs,
after all!).

http://en.wikipedia.org/wiki/Vacuum_Diagrams

Now somebody has.

I certainly enjoyed the book, especially the title story.

Weird, being on-topic, isn't it?

Why is it "for the wrong reasons"?  Some would say that if it leads
to predictions which match the observations closely enough to be
useful, it's good enough, at least in the limited range of
observations of interest where it is applicable ("our scale"), and
matching or not matching observations of reality is all that makes a
model "right" or "wrong."  No one except a theoretical physicist is
going to devote such huge amounts of computation time to a real world
problem where classical mechanics gives a good enough answer to
predict frex whether a building will stand or fall or whether a space
probe will successfully land on Mars or crash or miss the planet
entirely . . .


. . . ronn!  :)

Actually, I think you are both right in some respects.
All of our maths concerning physics (to any degree) are no more than
approximations. It just depends on how exact an answer you require to solve
a problem reliably.
If physics were anything more than approximate, we would have final answers
to all our questions.

How?  All physics does is model observations.  Physics was created out of
Natural Philosophy by tabling the question of the reliability of
observations.

Now, you can use the results of physics as a reliable model of what we
observe when you do metaphysics.  But, it is a really really good idea to
not confuse when you are doing physics and when you are doing something
else.  Otherwise you can wander off into the aether. :-)

What exactly do you mean when you say "free markets reliably regulate prices"?

I don't think there was any supply shock. But I have little doubt that
demand decreased with the world-wide economic slowdown.

One thing I know is that I have reliably been able to fill up my tank
wherever I have been in the US during the last year. Apparently the
market is doing a decent job of coordinating tens of thousands of
people to prospect for oil, extract the oil, transport the oil across
the ocean, refine it to the appropriate regional codes, transport the
gas to the stations, stock the gas, and dispense the gasoline I need
for my car, all without me having to wait in line or search for a gas
station that is not out of gas. That makes me happy.

Exactly what I wrote.  As a corollary, I am suggesting that the spike in oil
prices was primarily due to non-market forces.

That hardly explains a sudden, huge increase in the price.  From what I
recall from college economics, decreased demand generally depresses prices,
all other things being equal.

You obviously weren't in North Carolina, where stations were out of gas and
prices were the highest in the nation recently (and where my mother was very
happy to own a Prius).  But what does that have to do with price regulation,
by market forces or otherwise?

Models make predictions. And over time models have made predictions with
greater accuracy and that cover more situations that previous models failed.
Mercury anyone?

Models also allow us to re-create phenomena for our own purposes.

Which definition of "tabling" are you using here?

<G> I think the implication of what I wrote before is that for most of us

I would think it quite different when having a formal discussion.

So, meaningless. Or so broad as to have no useful meaning.

Oil been coming down for several months now.

I've never been to North Carolina. But I'll bet there were either
"price gouging" laws or credible threats  to gas stations who charged
prices that were said by some to be too high.

> by market forces or otherwise?

The prices coordinate the entire process I described.
