Good!! After we agree on what the 2ndlaw says, I will deposit

There are several completely equivalent statements of the 2nd law.
How about this one:
It is impossible to convert heat completely into work in a cyclic
process.

Well?
Taking that definition as too vague, I looked up the 2nd law on
yahoo and found this:
From Wikipedia:
The formulation of the second law that refers to entropy directly is
as follows:
Note that from the mathematical definition of entropy [see next
sentence], a process in which heat flows from cold to hot has
decreasing entropy. In a system, a process that occurs will tend to
increase the total entropy of the universe.
Taken together, this means that overall, heat will flow from a hot
to a colder body.
Science holds that heat represents the bottom of the ladder of forms
of energy. Taking heat as the lowest form of energy and stipulating
that the 2nd law of thermodynamics says that energy generally flows
from a higher to a lower form, Physics concluded that this will
eventually end in “the heat death” of the universe, in which all forms
of energy would have converted into heat and from then on the universe
will endlessly expand and the heat level will steadily decrease.
Question for PD: Do you agree with Physics about this, and do you
therefore agree that the 2nd law can be expressed thus:
As time passes in the universe, energy will flow from a higher to a
lower form, in which gravity is the highest form of energy and heat
the lowest?

PD is wriht in thas there are many 2xt-law formulations, but he has
yet to prove they are all equivalent. I'd already posted links at
Maxwells_Demon@eGroups where the law was dispelled. He has yet to
answer the rebuttals by Loschmidt, the Gravity Wheel, and my
ambivectoral temperature and path-function argument.

"Taken together, this means that overall, heat will flow from a hot

"the 2nd law of thermodynamics says that energy generally flows from
a higher to a lower form" "But it doesn't say that."
That IS what it used to say! When and why and how did who change it?

Ok, PD; in order to avoid ambiguity as to what we are betting about,
lets refine the terms. Independently of the 2nd law of td I bet you at
least $10,000 at 20;1 that the following conclusion of Physics is
false:
"Physics concluded that this will
eventually end in 'the heat death' of the
universe, in which all forms of energy
would have converted into heat and from
then on the universe will endlessly
expand and the heat level will steadily
decrease."
In the prior sentence, the word "this" refers to and means "that
overall, heat will flow from a hot to a colder body".
glird
Lower temperature is not a "lower form" of energy. It is the *same*
form of energy (thermal) at a lower temperature.
Is this difficult?

Where? When?
You are betting $10k that the universe will not end in a heat death?
When will the bet be decided?

Wait, are you saying that the 2nd law says that heat will not flow
from a cold body to a hot body? It doesn't say that. That's what a
kitchen refrigerator does. Perhaps you don't understand the 2nd law.

Evidently it is, to you. Let's try again.
I wrote, "Taking heat as the lowest form of energy .. the 2nd law of
thermodynamics says that energy generally flows from a higher to a
lower form". You objected, "A lower temperature is not a "lower form"
of energy."
Though true, it missed the point, which - though you denied it - was
that heat (thermal energy) is taken as the lowest form of energy and
gravity the highest; and the 2nd law says that _*ENERGY*_ "generally
flows from a higher to a lower form."
<>>> But it doesn't say that. >
><< That IS what it used to say! >
>
>< Where? When? >
On page 6 of "Heat-power Engineering" by Barnard, Ellenwood and
Hirshfeld, 1926, the following definition of the 2nd law is given:
"No machine, actual or ideal, can both completely and continuously
transfer heat into mechanical energy."
On page 320 of "The Elements of Physics" by A. W Smith, 1938, this is
written: "It [the 2nd law of td] merely states that heat of itself can
only flow from higher to lower temperatures and no exceptions to this
rule are known."
On page 263 of "Physics Principles and Insights" by I. M. Freeman,
1973, it says, "An independent proposition, supplementing the first
law, has been formulated to show what processes can be expected to
take place. It is called the *second law of thermodynamics*. This law
is subtle, and there are several equivalent ways of stating it."
After providing several such ways of stating the 2nd law, Freeman
says on page 269, "the second law of thermodynamics asserts that
natural processes always operate in the direction of greater disorder
as time passes -- that is, of two states of an isolated system, the
more disorderly state is the later one. The conversion of other energy
forms into heat always results in an increase in disorder -- an
increase in entropy -- and the fate of all kinds of energy is their
ultimate conversion into heat."

Since PD hasn't answered this question, I will rephrase it after
giving the rest of Freeman's above-quoted passage.
"There is no reason to doubt that the universe as a whole is tending
toward a final state in which all matter will be at the same
temperature and all forms of energy ... will have been converted into
heat. The German chemist Walther Nernst called this state of maximum
entropy, marked by an end to all natural processes, the 'thermal
death' of the universe."
Ignoring for the moment the definitions in which heat per se flows
from a higher to a lower temperature; and concentrating on the
portions saying that the fate "of all kinds of energy" is their
ultimate conversion into heat; why do you deny that the reason WHY
Physics thinks that ALL forms of energy will convert into heat is
because heat is considered to be the lowest form of energy on the
ladder?

I am not trying to equivocate in order to avoid betting, PD. Are

In order to avoid ambiguity as to what we are betting about, I will
restate it thus:
Given the following premise: "Gravity is the highest form of energy
and heat the lowest" (1), I bet you at least $10,000 (2) at 20:1 that
the following conclusion is false:
"Given that gravity is the highest form of energy and heat the
lowest, this will eventually end in 'the heat death' of the universe,
in which all forms of energy will have converted into heat and from
then on the universe will endlessly expand and the heat level will
steadily decrease."
I bet that I can prove TO YOU that the conclusion is false. The
winner of the bet will be decided by you within a few months, at
most.
There is a new aspect Id like to add: The loser of the bet has the
option of activating the next bet in the following list and the next
loser has the same option wrt bet #3, etc, until we get to the final
bet on the list. The WINNER of the penultimate bet has the option of
choosing whether or not to activate the final bet. Each new bet will
double the amount of my prior bet and triple the odds. (3)
I will construct the list if you agree to the terms. You may reject
any item on the list, before accepting the rest.
(1) A premise isn't automatically or necessarily true; it is a
statement that is to be accepted as valid without proof.
(2) You may raise the $10 k of the first bet if you wish.
(3) The first bet is NOT conditional on your accepting this new
aspect.

That's right, I'm denying that. Physics does not hold gravity to be
the "highest" form of energy and heat the "lowest". Period.
That's a classification all your own.

Because that's not what heat is. Thermal energy is just the energy
associated with random, stochastic motion. It is not a lower form of
energy. There are no "higher" and "lower" forms of energy.

Please state the exact statement you believe is wrong, and then make

Then we'll worry about how to find out which statement is right.

The statement you are claiming is wrong is that it will. In order for
that to be PROVEN wrong, you have to show that it cannot happen.
If in fact you admit that it could POSSIBLY happen, but simply will
not, then you're going to have to explain to me how you can know in
advance that something that could possibly happen will not happen.
I could do tht, PD, but you, as a physicist, will always find a way

I set YOU as sole judge of the winner of our bet. However, since it

So you have suddenly developed a morbid fear of actually following
through?
Your reply is an excellent example of why I was going to cancel the
bet: "it is becoming evident that you will either ignore or reword
logical arguments that prove I am right"
On second thought, though, rather than canceling the bet how about
changing the amount. If I send you $100 up front, will you bet you 2G
that i am wrong? You can state the bet however you want and you can
sill be sole judge of the winner.
(All I really wanted was for you to READ and UNDERSTAND my
arguments, even though i expect you to avoid admitting that they are
right. That's well worth 100 bucks to me; but not 10G.)

Because there are no forms! Those are pretty little shortcuts in
understanding. All chemical, mechanical, heat, etc. IS MOTION at a
subatomic, molecular, or material scale.
If you take heat and you add an unstable molecule, the molecule will not
convert into heat. UNLESS IT IS TRIGGERED.

There are no forms. Those are just labels. There are only higher or lower
AMOUNTS of energy. Energy conversion from one context (chemical) to
another (heat) always requires a trigger (coming in contact with its
neutralizing ions). There is no natural FORM CONVERSION without a
kickstart.

Gravity is a process not an energy. If you would like to say that
potential energy tends to kinetic energy then yeah. Except potential
energy is not a type of energy it is merely a calculation. In fact all
potential energy means is potential KINETIC energy that could be
achieved.
Say I have a planet in a very lonely area of space. Say then I have a
brick somewhere near that planet. If I drop the brick it will gain
kinetic energy. In the process it loses potential energy (relative to if
you dropped it from the new instantaneous position). Potential energy is
not actually converted. It's just forecast as there being less to achieve.
The proof of this is that potential energy does not exist in the brick.
All I have to do is move the planet and its potential energy increases.

Anti is right. There is no hierarchy of forms of energy!

Where did it say that? Even if/when the universe suffers "heat death"
there will still be matter, and therefore Gravitational energy,
nuclear energy, electrical energy. Just not enough to change the
thermodynamic state of the system.

Yes, heat energy is the energy of motion. And you are right there is
no Ladder/tree/hierarchy of energy.

WRONG. Entropy increases. That says nothing directly about energy
forms.

Be careful how you phrase that. Kickstart sounds like a catalyst or
similar is required.

This is a little nit picky, Anti. Though you do make clear elsewhere
these are labels. This part is almost an epistemological discussion.

Whether the "form" of energy changed, the same amount of energy
existed before and after the brick started moving. It is convenient to
say potential energy was converted to kinetic energy.

You definitely have THAT part right!
