Take a box full of photons.
Gravity - Photons pick up energy as they head down and so the ones at the bottom exert more pressure at the bottom
than the top - same as weight/mass
Inertia - Accelerate the box and we blueshift the photons at the back and redshift the front ones - more pressure
at back than front - inertia.
Photons have no mass but........................
Mr Forbes
it seesm that you stole some idea
but you sto;e it not good enough
see my 'Circlon idea'
it is not exactly photons
photons are different than the 'Circlon'
yet might be 'cousins ' .....

see my ''Circlon''' and some applications of it

San i you are rigth
but youdont know why you are right !!
(:-)

you are right because
th e mass of the real single photon is
exp-90 KILOGRAMS OF THE ONLY MASS THAT EXIST !!

and please dont forget who told you that
as the first one

and since you are good in quoting
then go on with it and dont forget to quote the anonymous

Sami
at this case you are right
yet there is no chance that you will understand why you are right
so here it is

the real single photon mass (yes mass
th eonly mass )
exp - 90 KILOGRAMS !!
again
exp-90 KILOGRAMS OT THE ONLY MASS THAT EXIST !!

so since you are JUST a very good quoter
please dont forget who told you that for the first time in

Momentum is conserved for your closed system box.
----------------
and the momentum of thephootn is

Ph momentum = hf/c
so
nothing in it is relativsic**
it was found 5 years before SR
and nothing that Planck s
meanderings tools -
used was not moving
for that experiment
IT HAS NOTHING TO DO WITH SR!!
so 1
to Forbes
you are wroong and anoying me
while you say that th ephotonhasno mass
2
for the Genus honest teacher PD:

all the above Planck experiment was done
AND MEASURED - just in one frame!
and not to mention that The Gamma factor does not apply to photons

and in addition to the above
nothing in the formula of photons energy
is to multiply photon energy
dimension s
by7zero !!

so nothing to do with SR
and the mass of the photon is the only mass that exist
not relativistic and not schmelativistic !!
just mass !
so again
don t forget who told you that for the fist tome in history

The "inertia" case is straightforward, and goes back to the physics of
the 1870s.
The "gravity" case is newer, and for many (perhaps most), was
unexpected. But experimentally, 'tis what we see.
That the "weight" of the photons in both cases is the same is just
what is predicted by general relativity (follows directly from the
equivalence principle). Surprising to see you post such blatant pro-GR
propaganda!

Perhaps photons contain rest mass and zero inertial mass

I think the evidence for gravitational red/blue shift (the Pound-Rebka
experiment) ignores the influence of gravitational potential energy on
Fe itself. Quantized molecular energy levels are a function of total
energy, which includes KE and gravitational potential energy. In
other words, gravitational potential energy MUST influence the
wavelength of Fe emission. If gravity indeed directly decreased
photon energy in the Pound-Rebka experiment, what gains the released
energy?

Einstein used the "principle of equivalence" to conclude, "Rate of
clocks at different heights was altered according to the gravitational
field". The principle of equivalence is the equivalence of rest mass
and inertial mass. Without inertial mass or rest mass, gravity cannot
cause redshift in photons, or a difference in a photon's clock rate.
Rest mass (not inertial mass) changes potential energy with height.
Inertial mass opposes the result of force (acceleration), without
regard for the type of applied force. Because photons have neither
rest mass nor inertial mass, photons have zero gravitational redshift.
Photons can convert to other energies without the burden of also
converting kinetic or potential energy due to mass, to the other
energy.

Many isotopes (H3, S35) have decay products that have more mass than
the original isotope. For example:

C14 --> N14 + e
14.003241 14.003074 .00055

Therefore, mass is not a requirement of all types of energy (possibly
including photons).

Each type of force is a property of a certain type of energy
(coulombic, magnetic.) Therefore, mass is a property of a particular
form of energy. If electrons contained only mass, they would not
differ from positrons. Mass is a form of energy that might not exist
w/o other types of energy. C14 indicates that atoms contain massless
energy and the massless energy could be greater than the energy due to
(rest) mass.

For example, the amount of magnetic energy within a molecule is not a
function of mass.

Relativistic speeds add more energy than KE. The form of this energy
is not likely pure mass. An electron with 3x original energy can
start forming electron-positron pairs.

Oops, I'm on a tangent.

Gravity is not a property of photons. There is a possibility that
photons contain mass (accounting for gravity.) The relativistic speed
of photons does not indicate that photons have mass. Relativistic
speed only increases the energy of things that already have mass.

interesting information
but wrong INTERPRETATIONS !!!

your example if right means for me
decay of particles is not always exothermic !!!
you got there is a di d the calculation
you go there ''excessive 0.000383 Amu
right ??
it means the process is exothermic
and i am not shocked about it
because i dont remamber that decay
must be endothermic or exothermic
it can be each of them

please have a look at my abstract
and tell me if i know something of your staff

it is from 1993 !!!!....
and it i s only a little abstract of my **whole* book !!
so i knoe something about binding enries of a great deal of cases
actually i solved the geometric srtucture of all the periodic table
of elements
and i cannot be done without vast knowledge
of that issue
there are many cases in which a particle has some
em waves around it that give it more mass
forinstance
a magnet has a field around it
but its mass is so small that cannot dedetected

one of my historic findings is that
the real single photon mass is
about Exp - 90 Kilogram !!
do you get how tiny it is ???
and how elusive it is
------------------
now
my prove that E=hf HAS NOTHING RELATIVISTIC !
ie no relativistic mass in it
and i hope you understand that mass is hiding in that h ...
so my above prove is much general and stronger than your example !!!
i showed as well that the paradigm that
no mass can reach c
while v= c Gamma is undefined !!!
so o one has the permission just his own guess !!
and my second prove that
E=hf is another confirmation for the other interpretation that
there is** no** relativistic mass
and even more reasonable than say
jsut motion can create mass from nothing but motion
and while motion stops Hukus fokus --that relativistic mass
DISAPPEAR ...!!!
and i had other proves for it yet
not necessary now ...all i brought untill now is enough ..

"The result confirmed that the predictions of general relativity were borne out at the 10% level.[3] This was later
improved to better than the 1% level by Pound and Snider.[4]

Another test involving a space-borne hydrogen maser increased the accuracy of the measurement to about 10-4 (0.01%).["

The notion of a photon gaining energy in a grav' field is certainly consistent with BaTH.

I am wondering if experiments have been done from great heights with sound waves - I wonder if a phonon picks up
speed or frequency if it travels down?

"No rest mass" isn't clear enough?

First, this isn't known for certain. The standard classical and
quantum theories either predict or assume this (the classical theory
predicts it; for the quantum theory, it can be done either way). But
experiment is the decider, not theory. So one needs to look at
experimental evidence. Given the limitations of experiment, it isn't
possible (or hasn't been yet) to exclude the possibility of a very
tiny rest mass. A few years old, but a good review is Liang Cheng Tu,
Jun Luo, and George T. Gillies, "The mass of the photon", Reports on
Progress in Physics 68, 77-130 (2005). By now you should be quite
familiar with this, since this paper has been mentioned in many
threads in which you have participated over the last 1/2 decade, and,
IIRC, has been mentioned specifically to you. If, for some reason, you
haven't read it yet, do so!

Second, I know you don't like the idea of "rest mass", "relativistic
mass", etc., what with your "one kind of mass" line. A whole bunch of
physicists also agree that "one kind of mass" is the way to go, and
therefore have decided that "mass" should always mean "rest mass". If
you want a good word for what was once called "relativistic mass", try
"energy". It's cohesive and complete: "mass" (i.e., rest mass) is the
magnitude of the energy-momentum 4-vector, "energy" is the time-
coordinate-axis component of the energy-momentum 4-vector, and
"momentum" is the 3 spatial components.

Earlier, "mass" was used rather ambiguously (and still is in some
writing). But don't be confused by that! The modern statement that
"photons have no mass" refers unambiguously to rest mass!

Third, in light of the above, you had better clarify just what kind of
"mass" _you_ mean with your "one kind of mass", if you want other
people to understand you. How about (a) and operational definition of
_your_ mass, and (b) include an operational definition of your mass
for moving objects.

Fourth, the experimental upper limit on the rest mass of the photon is
_much_ higher than your proposed mass of a "photon". However, keep in
mind that this upper limit is for a conventional photon, of energy
E=hf (and thus of easily detectable "relativistic mass"), rather than
your "single photon" (i.e., some kind of "sub-photon").

way do you talk so much ??!!
lets take the 'clasic' example of phottn energy
and later we wil see about
phootn momentum that is
hf/c
so that is why
E=hf is so important to examine

WHAT IS RELATIVISTIC IN
E=hf
Planck **didnt use*** any moving tool
or measuring equipment !!
it was all in just one single ;""frame ''
(that was defined ,measured ,formulated
5 years before any SR was published
and noting in formulation of it used any

btw
please dont tell us that c is relativistic

That wasn't what you asked! You asked "just tel us loud and clear do
photons have mass or not ??" Which is why I answered a question about
photon mass. I wrote a lot since I've answered the same question from
you before, and since you ask again, I must assume that you didn't
understand the answer the last time around.

But since you didn't like the answer to that question and now ask a
_completely_ different one: nothing. That is, there isn't anything
relativistic in E=hf. Is there supposed to be? Relativity is not a

It doesn't have any mass in it. E=hf is about _energy_, not _mass_.
These are different things. There are accepted technical usages of
these terms, with narrow, well-defined meanings. E=hf doesn't have
what physicists mean by "mass" in it. I don't know what _you_ mean by
mass, because you haven't said. Will you say? Below, I ask.

I know you keep saying that E=hf "has mass in it". That's why earlier,
I wrote the paragraphs below. Basically, you are using a _different_
definition of mass from that used in modern physics (and it's also
different from Newton's definition).

To repeat what I already wrote earlier in this thread, "photons are
massless" means that photons have zero rest mass. Rest mass is the
magnitude of the energy-momentum 4-vector.

The E-M 4-vector is P=(E/c^2,p_x,p_y,p_z). (That's the contravariant
vector - the covariant vector is neater, = (-E,p_x,p_y,p_z).) In
general, rest mass is m = |P|, in appropriate units (and sign,
depending on our choice of sign in the metric). So, we have:

m = sqrt(E^2/c^4 - |p|^2/c^2).

For your 1kg box, stationary, P_box = (1kg,0,0,0). If we add 9e16J of
EM radiation, stationary (i.e., in a bunch of standing wave modes in
the stationary box, on average), this has P_rad = (1kg,0,0,0).

The total E-M 4-vector is then P_total = (2kg,0,0,0). From which the
rest mass of the system (box + contained radiation) is 2kg.

(E=hf is entirely irrelevant in the above, unless you want to count
photons. All of the momentum/mass/energy stuff follows purely from
classical (i.e., non-quantum) considerations.)

But wait! It gets better!

Consider a collimated pulse of light, of energy 9e16J. This has
momentum p=E/c (collimated, so we can assume the energy-momentum
relation for a plane wave is good). Let us assume it is travelling in
the x-direction.

The 4-vector is P_collimated = (1kg,3e8N.s,0,0). The magnitude is
zero; rest mass of the collimated pulse is zero.

Now consider a spherically symmetric expanding pulse, of energy 9e16J.
Every point on the surface of the expanding pulse has some momentum,
directed outwards. Due to the spherical symmetry, the total momentum
is zero.

So, P_spherical = (1kg,0,0,0), and the rest mass of the spherical
pulse is 1kg.

Ponder the above results for what is effectively a plane EM wave, and
a spherical wave. We see the statement that "photons are massless",
i.e., have zero rest mass. We also see (single) photons being defined
in terms of plane wave modes. So:

(i) Massless photons are plane wave photons.

(ii) The rest mass of a system is not the rest mass of its components
(follows directly from m = sqrt(E^2/c^4 - |p|^2/c^2, since E is
scalar, and p is a vector quantity).

(iii) For non-plane wave radiation, we can add a bunch of plane wave
modes. To obtain a standing wave in a box, with a total of a single
photon, that's a half-photon going one way, and a half-photon going
the other way - the usual recipe for non-zero rest mass.

Stop right here! Nobody is saying that a "box of photons" is massless.
(Well, some people would say it, but that's overgeneralising the
"photons are massless", and isn't what the theory actually says.)

What (conventional) theory says is that m = sqrt(E^2/c^4 - |p|^2/c^2),
and a box of photons of total energy 9e16J and zero momentum quite
clearly has a rest mass of 1kg. Which is not zero.

What conventional theory says is that a single photon in a plane-wave
mode, or N photons all in the same plane wave mode (or plane wave
modes with parallel (_not_ including anti-parallel) k) have zero rest
mass. If you want to disagree with that go ahead, but it doesn't seem
at all useful to spend time disagreeing with a mis-interpreted cartoon
of what conventional theory says.

It's an old definition of mass. And out of the confusion of "mass" as
possibly "relativistic mass", "rest mass", "longitudinal mass",
"transverse mass", "volume * density", and perhaps more, _modern_
terminology is:

(a) the invariant quantity is simply called "mass", and

(b) the total quantity, which changes with (kinetic) energy, is
"energy". This is what you want to call "mass", except for the
different units.

So, you want to call (effectively) total energy "mass". That would
work, but is it useful? It conflicts with existing terminology, and
conflicts with some everyday ideas about "mass". (Which is why there
has been a revision of terminology.)

Yes, one can call "total energy" mass. What do you propose calling the
invariant mass? Back to always "rest mass"? (Or "invariant mass" would
do, too.) Certainly one shouldn't just throw away invariant mass,
since

Anyway, that's just quibbling about terminology. I don't see any
confusion. You, OTOH, clearly do see some advantages. Fair enough.

But keep in mind that while your revised terminology would have
photons having "mass", that's identical to conventional terminology
saying that photons have "energy", or older terminology saying that
photons have "relativistic mass". Which really has nothing to do with
the conventional statement that a (plane wave mode) photon has zero
rest mass.

media it is claimed it simply 'can't 'by definition, be' for light.
No, this is wrong. Specifically, it has been shown that energy in
other wave phenomena has inertia independently of the mass of the
medium, with energy-momentum relationship p=E/v, where v is the speed
of transport of the energy (and not just waves, it also applies to,
e.g., transport of thermal energy by conduction). Light is simply
treated identically, and not as a special case.

If you want to say that light has "mass" due to its inertia, you must
also say that other waves have "mass" due to their inertia as well, in
addition to the mass of the medium.

Sorry, I don't know a good English language reference. Umov's 1874
paper is (in Russian) in his "Selected Works", and also appeared in
German, Umov (Umoff), N.A., 1874. Beweg-Gleich. d. Energie in contin.
Korpern, Zeitschriff d. Math. and Phys. V. XIX. This hasn't gotten
much attention in the Western literature, since the relativistic
energy-momentum relationship covers it simply and compactly.

The basic problem with Aetherist's (and other people's) attempt at non-standard
usage, is that "mass" carries the historical baggage that it represents "how
much stuff is present" [*]. Since "how much stuff is present" cannot change if
one looks at an object with different coordinates or from a different frame,
"mass" MUST be invariant under changes of coordinates. Hence the modern usage is
BY FAR the best approach. IMHO this is a major part of why that is the modern
usage of the word "mass".

[*] That is certainly how "mass" was discussed in my high school
physics class. While the major point was to differentiate weight
from mass, the principle still holds in ALL theories of modern
physics.

BTW this was not a "revision" of terminology, this was a SELECTION from among a
set of alternatives introduced by relativity, selecting the usage that most
closely represents the previous usage:
* Mass, meaning the norm of an object's 4-momentum, goes smoothly into
the m of Newtonian mechanics, as in F=ma and p=mv.
* Energy, meaning the time component of an object's 4-momentum in an
inertial frame, goes smoothly into a new "rest energy" plus kinetic
energy.
* The momentum equation of Newton, p=mv, is a relationship between
3-vectors, and is directly generalized using 4-vectors: P=mV;
"m" is obviously the norm of the 4-momentum P.
* None of the alternatives do the above.
* None of the alternatives for mass represent "how much stuff is present".

So that is why we say "photons have no mass" -- the norm of their 4-momentum is
identically zero in free space. Though if one goes deeper, in QED one finds that
the propagator for a photon has no mass term (which applies even in situations
other than free space). "Porat" and "car" are just completely clueless, and
"Aetherist" is wrong.

When one seals a bunch of photons into a box, the INDIVIDUAL photons
remain massless (in the sense of their propagator in QED), but the
BINDING ENERGY involved in keeping them inside the box introduces a
net mass that is measurable for the box plus contents. In the real
world, the photons are quickly absorbed by the mirrors, heating them.
Heating such an object is KNOWN to increase its mass -- so the modern
usage is the only one that directly satisfies energy and momentum
conservation (4-momentum conservation).

of why that is the modern usage of the word "mass".
While I know you don't pay any attention to what I say I've consistently
argued that the term 'rest mass' is an emergent quantity, and only
momentum is primal (as in a fundamental of physics). In turn that the
actual momentum of any 'massive' object is relative to the universal
background, the CMBR and 'relative' momentum between FOR's is, as always,
mdv... Thus energy, momentum, ... etc. does not just 'appear/dissappear'
when changing relative FORs... everything has a common base and the
conservation arrise from this fact.

BTW this was not a "revision" of terminology, this was a SELECTION from among a
set of alternatives introduced by relativity, selecting the usage that most
* Mass, meaning the norm of an object's 4-momentum, goes smoothly into
the m of Newtonian mechanics, as in F=ma and p=mv.
* Energy, meaning the time component of an object's 4-momentum in an
inertial frame, goes smoothly into a new "rest energy" plus kinetic
energy.
* The momentum equation of Newton, p=mv, is a relationship between
3-vectors, and is directly generalized using 4-vectors: P=mV;
"m" is obviously the norm of the 4-momentum P.
* None of the alternatives do the above.
* None of the alternatives for mass represent "how much stuff is present".
So that is why we say "photons have no mass" -- the norm of their 4-momentum is
identically zero in free space. Though if one goes deeper, in QED one finds that
the propagator for a photon has no mass term (which applies even in situations
other than free space). "Porat" and "car" are just completely clueless, and
"Aetherist" is wrong.
Photons do have 'mass' in the sense that:

E = pc

And

p = mv

and with v = c

E = (mc)c = mc^2

Photons do NOT! have any 'rest mass' but all energy has 'mass' in the form
of momentum and all energy thus gravitates. This brings a thought to my mind
that given the CMBR and its power density of sT^4 (s -> Stefhan-Boltzmann's
constant) it certainly will have 'massive' gravitational effects throughout
space.

When one seals a bunch of photons into a box, the INDIVIDUAL photons
remain massless (in the sense of their propagator in QED), but the
BINDING ENERGY involved in keeping them inside the box introduces a
net mass that is measurable for the box plus contents. In the real
world, the photons are quickly absorbed by the mirrors, heating them.
Heating such an object is KNOWN to increase its mass -- so the modern
usage is the only one that directly satisfies energy and momentum
conservation (4-momentum conservation).
I deliberately stated that 'I Know! mirrors aren't perfect'. I also
know that you physically cannot put 9E+16 J of photons in a box.
Further, I stated that you, by any physical measurement, cannot tell
whether the box contained a 1 kg foam or photons WITHOUT looking
inside. The 1 kg of foam will behave EXACTLY! like the photons.
Mass IS! mass, all theoretical mumbo jumbo aside.

Since, the equation say mass, it weighs like a mass, has inertia
like mass, behaves like mass, it is illogical and stupid to claim
it not mass. Mass is not synonomous with 'rest mass'...

The basic problem with Aetherist's (and other people's) attempt at non-standard
usage, is that "mass" carries the historical baggage that it represents "how
much stuff is present" [*]. Since "how much stuff is present" cannot change if
one looks at an object with different coordinates or from a different frame,
Agreed...
Post by Tom Roberts
"mass" MUST be invariant under changes of coordinates.
While I agree, this is not ordained by God. Thus there is no MUST...
The MUST is ordained by man: Arbitrary human choices, such as selection of
coordinates, cannot possibly affect any natural phenomenon, such as "how much
stuff is present". This is inherent in the observed ability for people to do
physics -- there is a common world "out there" which we can all observe and
model....

Ultimately this comes down to the distinction between world and
model; coordinates are part of the MODEL, but "stuff" is part of
the world. The model cannot affect the world.

Hence the modern usage is BY FAR the best approach. IMHO this is a major part
of why that is the modern usage of the word "mass".
While I know you don't pay any attention to what I say I've consistently
argued that the term 'rest mass' is an emergent quantity, and only
momentum is primal (as in a fundamental of physics).
"Rest mass" is irrelevant. The mass of an object is the norm of its 4-momentum.
One can easily show that when its 4-momentum is projected onto its (inertial)
rest frame, its total energy is equal to its mass.

IMHO "Rest mass" is an oxymoron, because "rest" has nothing to
do with it (mass is invariant). At a minimum, the first word is
redundant; n the case of photons, "rest mass" is inapplicable.
Post by Aetherist
In turn that the
actual momentum of any 'massive' object is relative to the universal
background, the CMBR and 'relative' momentum between FOR's is, as always,
mdv... Thus energy, momentum, ... etc. does not just 'appear/dissappear'
when changing relative FORs... everything has a common base and the
conservation arrise from this fact.
Your fantasies and dreams are not a constraint on nature, or on physical
theories and models of nature.

When you don't understand basic physics, you can write down nonsense like this.
Writing nonsense in the form of equations does not change the fact that it is
nonsense. But since you did not bother to describe what the symbols in your
equations mean, you have deluded yourself into thinking they are not nonsense.

Specifically: state what your "m" means, and note that it does
not apply when v=c. Be sure to read Einstein's paper on "E=mc^2"
VERY CAREFULLY (ditto for any other paper on the subject).

Moreover, above you said that you agreed with my statement "mass must be
invariant under changes of coordinates". Look at your equations above and note
that your "m" is NOT invariant.

How does moving away from or toward a light source change "how
much stuff is present" in the light beam?

Are you unable to see the inconsistencies of your approach?
Post by Aetherist
Photons do NOT! have any 'rest mass' but all energy has 'mass' in the form

Not so. It's just that the "source" of gravity is not merely mass, it is the
entire energy-momentum tensor. All energy "gravitates" because it contributes to
the energy-momentum tensor (not because all energy "has mass"). This completely
resolves your confusion. But you clearly do not know enough modern physics to
understand it.

BTW momentum is not some "form" of mass. They are incommensurate.

A wave on the surface of the ocean clearly has energy. What is
its "mass"? Where does that "mass" reside? How much "stuff" is
contained in the wave, and what is it made of? How does moving
relative to the surface affect "how much stuff is present" in
the wave? How is this related to the old question "Where does
the kinetic energy of a bullet reside?"

Are you unable to see the inconsistencies of your approach?

Since, the equation say mass, it weighs like a mass, has inertia

The mass of box+contents is the norm of the 4-momentum of box+contents. One
obtains the 4-momentum of a bound, compound system like this by adding up the
4-momenta of its constituents. In particular, one CANNOT simply add the masses
of the constituents [#]. There is nothing "illogical and stupid" about applying
the definition of "mass" properly.

And, of course, YOUR equation above is nonsense, so "it" does not "say mass".

[#] Example: consider the decay pi0 => two photons. Initially
the pi0 mass is 135 MeV/c^2, but the masses of the final photons
are both zero. Mass is not conserved for the individual
particles. But 4-momentum is conserved in this decay, and the
SYSTEM consisting of the two final photons has a mass of 135
MeV/c^2 (though in practice the mass of such an unbound system
is essentially useless).

In modern usage it is, whenever "rest mass" has meaning.

modes with parallel (_not_ including anti-parallel) k) have zero rest
mass. If you want to disagree with that go ahead,
I don't disagree, no plane wave of any sort has any rest mass.
It is the directionalized momentum carried by the medium (which

Based on the current definitions, yes. I just would add that
p = mc is always valid as well. One just needs to realized
that m DOES NOT! need to be 'rest mass'.

'Tis a dangerous philosophy to simply declare that you know the One

This is not a great approach. Momentum is not defined by a formula. It
is defined by being a vector quantity that is conserved in a closed
system, regardless of interactions internal to the system. There are
different contributions to that total momentum, depending on what kinds
of entities are present in the system, and each of them may have a
different formula for calculating that contribution. It is remarkable
that, even with different formulas for calculating momenta for different
kinds of entities, it is still true that the sum remains constant.

So, to be clear, the box weighed 1 kg, the photons weigh 1 kg so
the total is 2 kg.  Without opening the box one cannot know
whether the are photons or marbles in the box, just that whatever
it is 'masses' as 1 kg.
Hmmm, it act like a mass, weighs like a
mass has inetia like a mass, but they're 'massless'.
Stop right here! Nobody is saying that a "box of photons" is massless.
(Well, some people would say it, but that's overgeneralising the
"photons are massless", and isn't what the theory actually says.)
Tell that to Paul Draper :)  He insisted that photons 'are massless'
and that one must not infer from their momentum that they have any
mass.
Argue with what he actually says, not a cartoon of it. He has said
quite clearly, many times, that the rest mass of a system is not equal
to the sum of the rest mass of its components. He has no problem with
the rest mass of a box of photons being non-zero, even if the rest
mass of the photons is zero.

So the argument leaves physics and becomes one of terminology, at
best.

It isn't even usefully an argument about terminology unless you can
cough up a good enough definition of what you mean by "mass". How

If your definition is tied to momentum as closely as the above
suggests, then the modern term used in physics would be "inertia".
Which would make your argument purely one of whether 'tis better to
use the word "mass" or the word "inertia", which is rather devoid of
physics.

And such choice of meaning of "mass" means that "mass" depends on our
(purely human) choice of coordinate system. Not a fundamental property
of anything then! (No more than position or velocity are fundamental
properties of an object - they depend on our choice of coordinate
system.)

NO! I think that invariant mass is just another form of the medium
that allows for it to be at 'relative' rest in a FOR. Vortex rings
for example. Vortices exhibit inertia and thus can be construed to
have a 'rest' mass. Perhaps I have a much more unified approach to
physics that you. To me, there is NO! difference other that the
structural form of the momentum. Circulation certainly can be
self contained and at relative rest to a system of measure. The
aethe entities are the same, have the same momenta but because of
what they are manifesting can be construed to be invariant mass
or a photon, but Underneath, its the very same stuff. It all has
momenta & inertia, thus, but the strong equivalence principle, mass.

Massless means you can express in an equation that under no
circumstances has mass in it. This is not the case in our
universe. The momentum equation is:

p = mv

and m has inertia! Invoke the strong equivalence principle
since you seem to like thing explained to you in that fashion!

If p in the case of photons had no mass a.k.a inertia then
they could/would not contribute to the mass/weigh/inertia

You: "Yet you are the one who says that fields, let alone
quantized fields, cannot be considered part of a
fundamental explanation. And yet here you are invoking
one. Hmmmm.... "
A current clarification for you on this point.
A 'Field' is the manifestation of a underlying physical process
like pressure, density, ... etc. Claiming a "Field' is
fundamental is simply a copout, not wanting to know the root
cause of same... But As I said in that thread I am consistently
consistent...

The terminology I am using for mass is invariant mass, just as Timo has
pointed out to you. What I have said in the past is that a system of
photons can have nonzero invariant mass, while each of the photons has
zero invariant mass. THAT is the statement made.
Well if you had said, that and agreed that momentum is 'massive'
as clearly demonstrated by the box full of photons illustration
there would BE! no confusion.
If I had said that, though, I would be misspeaking, because the momentum
does not have mass even if you put quotation marks around it. The
problem, I gather, is that you believe that if a system has invariant
mass, then you must find where in the constituents this invariant mass
resides, and this in turn stems from an assumption that invariant mass
is additive: that is, the total of a system must be numerically equal to
the algebraic sum of an equivalent property exhibited by the system
NO! I think that invariant mass is just another form of the medium
that allows for it to be at 'relative' rest in a FOR. Vortex rings
for example. Vortices exhibit inertia and thus can be construed to
have a 'rest' mass. Perhaps I have a much more unified approach to
physics that you. To me, there is NO! difference other that the
structural form of the momentum. Circulation certainly can be
self contained and at relative rest to a system of measure. The
aethe entities are the same, have the same momenta but because of
what they are manifesting can be construed to be invariant mass
or a photon, but Underneath, its the very same stuff. It all has
momenta& inertia, thus, but the strong equivalence principle, mass.
Sorry, but to be honest, very little of this made any sense to me. Is
there a connection to the invariant mass as I use the term? That is, is
it possible to have a system composed of objects such that each of the
objects has zero invariant mass and the system has nonzero invariant mass?

All forms of energy has mass,
period, end of story!
And what is the basis for this statement? I take it that when you append
"end of story!" this is a marker for some axiom that you take to be true
without necessity of evidence or proof.
See above...
So is the statement a *consequence* of your model? Or is it an assumption?

Not all energy has a measurable rest or
'invariant' mass. But, just because you cannot stop something
to 'weigh' it does NOT! mean it is massless. In our known
universe nothing is 'massless'.
See the previous two comments. I have no idea what you hope to gain by
putting "massless" in quotation marks. What I mean by "massless" is that
it has zero invariant mass, and that is a determination from
experimental measurement not by axiom.
Massless means you can express in an equation that under no
circumstances has mass in it. This is not the case in our
p = mv
and m has inertia! Invoke the strong equivalence principle
since you seem to like thing explained to you in that fashion!
You say, "the momentum equation is p=mv". This is precisely where I have
a dispute. This is an equation that relates momentum and other
properties of a body FOR A CERTAIN CLASS of bodies. It is not a
definition of momentum. Momentum is defined as the vector quantity of
dynamical systems that exhibits conservation in closed systems -- and it
is the property that is associated with the invariance of the laws of
physics with translation. HOW YOU CALCULATE the momentum depends on what
the object is -- for some kinds of objects, the momentum is related to
this and that property of the object (rest mass and velocity, for
example), and for other kinds of objects, the momentum is related to
OTHER properties of the object (the wavelength, for example). It is
remarkable that we have all these DIFFERENT relations for different
kinds of objects that can inhabit a system, but that the sum of all
those different kinds of contributions ends up being constant in a
closed system.

(Conservation of energy is just as remarkable, given that you're adding
together terms for ordered translational kinetic, disordered
translational kinetic, rotational kinetic, potential energy of various
kinds, rest energy, etc., that all have different methods for
calculating each contribution, and yet the scalar sum ends up being
constant for a closed system.)

If p in the case of photons had no mass a.k.a inertia then
they could/would not contribute to the mass/weigh/inertia
of the box, period. You seem to like logical contradictions!
And this is the assumption I pointed out before: You are ASSUMING that
mass is an additive property, and that the mass of a system MUST be
accounted for by the sum of the masses of the constituents, and that if
a constituent has no mass then it cannot contribute to the mass of the
system. The point I made in response is that mass IS NOT ADDITIVE in
this sense, nor does it NEED to be.

Yes... As Feynman would ask, What is matter, really? Maxwell-Kelvin
suggested vortex structures. Vortices are local circulations of a
medium. Vorices and their circulation opposites annilate just like
particle/anti-paricles. Vortices exhibit inertia, contain circulating
medium particles that have momenta, thus have an intrinsic mass
associated with them. Ring vortices have both spin (poloidal circulation)
and angular momentum (toroidal twist) and each has two states up/down
left/right, thus four distinct states up-right, up-left, down-right,
down left. Up-left & down-right or up-right & down-left are the state
anti-state for these and will cancel the circulation of both rings
when colliding. Other states like up-right, down-right or up-right,
up-left have other distinctive interactions. Really, go look at Maxwell's
paper "On Physical Lines of Force" and see how EM was actually modeled.
Vortex rings can & do have oscillating waves within their structure.
Both on the poloidal axis and toroidal axis. These, as you might
imagine can only be in whole number ratios of the diameter of either.
These are soliton states. Vortex ring systems are, by their very nature,
quantum, thus the superfluid results. If after this rather brief but
lengthy discription you still cannot get an inkling of how aether models
can map to the world we inhabit then look at Volvik's "The Universe in
a Heluim Droplet". But, the key is that which makes up the vortices
must seemingly must adher to kinetic theory of an inviscid medium and
is dicretely granular containing momentum & energy.

So, to be clear, the box weighed 1 kg, the photons weigh 1 kg so
the total is 2 kg.  Without opening the box one cannot know
whether the are photons or marbles in the box, just that whatever
it is 'masses' as 1 kg.
Hmmm, it act like a mass, weighs like a
mass has inetia like a mass, but they're 'massless'.
Stop right here! Nobody is saying that a "box of photons" is massless.
(Well, some people would say it, but that's overgeneralising the
"photons are massless", and isn't what the theory actually says.)
Tell that to Paul Draper :)  He insisted that photons 'are massless'
and that one must not infer from their momentum that they have any
mass.
Argue with what he actually says, not a cartoon of it. He has said
quite clearly, many times, that the rest mass of a system is not equal
to the sum of the rest mass of its components. He has no problem with
the rest mass of a box of photons being non-zero, even if the rest
mass of the photons is zero.
That's absolutely right. Timo speaks correctly.
Then you recant you earlier statements in threads like this;
http://tinyurl.com/3csrr6o
Me:  "It's mv, even for a so called photon.  In that case
m = h(nu)/c^2 and since v = c, p = h(nu)/c  The real
question there should be if the 'stuff' constituting
a photon isn't 'massive' how does it have momentum at
all?  I already know what you'll say, don't bother... "
You:  No, it is not.
Me:  "quantum entities having momentum/energy interacting
with each other in accordance with basic kinetic
theory of elastic bodies.  If, as you have claimed,
momentum can and does exist independent of mass
these entities do not need to be massive, a.k.a.
'material'.  There has never being a direct observance
of a reversal of time. "
Me:  "If, as YOU! have claimed, momentum can and does exist
independent of mass these entities do not need to be
massive, a.k.a. 'material'"
Here is where I was being clear that we are NOT! talking about
'rest mass' or 'matter'  BUT! just mass!
The terminology I am using for mass is invariant mass, just as Timo has
pointed out to you.  What I have said in the past is that a system of

It is to me, as I've just reiterated to you. I have no interest in what
goofy concept to "massless" you attach to that word other than what I
intend by it when I say it.
Goofy in what way???

I'm
pretty damned sure you knew what I was getting at in that
thread.  That the aether medium entities have momentum and
energy, thus, by definition, are also 'massive' but without
'invariant mass'!...

Me:  "Going by what your definition and argument was, remember
the lowly photon...  I'm not the one who invented the
massless momentum concept... "
You: "Yet you are the one who says that fields, let alone
quantized fields, cannot be considered part of a
fundamental explanation. And yet here you are invoking
one. Hmmmm.... "
A current clarification for you on this point.
A 'Field' is the manifestation of a underlying physical process
like pressure, density, ... etc.  Claiming a "Field' is
fundamental is simply a copout, not wanting to know the root
cause of same...  But As I said in that thread I am consistently

All forms of energy are mass?
No. Only concentrated energy for mass. Einstein called that C squared.
The rest is spread out energy for light and matter bond field.

Free particles are heavier.

So, to be clear, the box weighed 1 kg, the photons weigh 1 kg so
the total is 2 kg.  Without opening the box one cannot know
whether the are photons or marbles in the box, just that whatever
it is 'masses' as 1 kg.
Hmmm, it act like a mass, weighs like a
mass has inetia like a mass, but they're 'massless'.
Stop right here! Nobody is saying that a "box of photons" is massless.
(Well, some people would say it, but that's overgeneralising the
"photons are massless", and isn't what the theory actually says.)
Tell that to Paul Draper :)  He insisted that photons 'are massless'
and that one must not infer from their momentum that they have any
mass.
Argue with what he actually says, not a cartoon of it. He has said
quite clearly, many times, that the rest mass of a system is not equal
to the sum of the rest mass of its components. He has no problem with
the rest mass of a box of photons being non-zero, even if the rest
mass of the photons is zero.
That's absolutely right. Timo speaks correctly.
Then you recant you earlier statements in threads like this;
http://tinyurl.com/3csrr6o
Me:  "It's mv, even for a so called photon.  In that case
m = h(nu)/c^2 and since v = c, p = h(nu)/c  The real
question there should be if the 'stuff' constituting
a photon isn't 'massive' how does it have momentum at
all?  I already know what you'll say, don't bother... "
You:  No, it is not.
Me:  "quantum entities having momentum/energy interacting
with each other in accordance with basic kinetic
theory of elastic bodies.  If, as you have claimed,
momentum can and does exist independent of mass
these entities do not need to be massive, a.k.a.
'material'.  There has never being a direct observance
of a reversal of time. "
Me:  "If, as YOU! have claimed, momentum can and does exist
independent of mass these entities do not need to be
massive, a.k.a. 'material'"
Here is where I was being clear that we are NOT! talking about
'rest mass' or 'matter'  BUT! just mass!
The terminology I am using for mass is invariant mass, just as Timo has
pointed out to you.  What I have said in the past is that a system of
photons can have nonzero invariant mass, while each of the photons has
zero invariant mass. THAT is the statement made.
Well if you had said, that and agreed that momentum is 'massive'
as clearly demonstrated by the box full of photons illustration
there would BE! no confusion.
If I had said that, though, I would be misspeaking, because the momentum
does not have mass even if you put quotation marks around it. The
problem, I gather, is that you believe that if a system has invariant
mass, then you must find where in the constituents this invariant mass
resides, and this in turn stems from an assumption that invariant mass
is additive: that is, the total of a system must be numerically equal to
the algebraic sum of an equivalent property exhibited by the system
Post by Aetherist
All forms of energy has mass,
period, end of story!
And what is the basis for this statement? I take it that when you append
"end of story!" this is a marker for some axiom that you take to be true
without necessity of evidence or proof.
Post by Aetherist
Not all energy has a measurable rest or
'invariant' mass.  But, just because you cannot stop something
to 'weigh' it does NOT! mean it is massless.  In our known
universe nothing is 'massless'.
See the previous two comments. I have no idea what you hope to gain by
putting "massless" in quotation marks. What I mean by "massless" is that
it has zero invariant mass, and that is a determination from
experimental measurement not by axiom.
Post by Aetherist
This was my focus and key point
of that earlier thread.  Yuo argued M-A-S-S-L-E-S-S, period!
claiming the can be momentum without mass.  I said no way!
There can be momentum without the ability to measure an
invariant mass BUT! there is still mass present in the system
even in those cases as this clearly illustrates...
Post by PD
I have no interest in your claims of what I have said, provided that you
substitute *YOUR* understanding of mass for the meaning that *I* used in
my statements.
I provided the link so that anyone interested can go look for
themselves.  It clear, you said that photons were massless...

You're the one who is insisting that _something_ (everything? energy?
photons? what? Be clear!) has something you call "mass". _You_ are the
one who claims to have a point, but you refuse to be at all clear as
to what it is. What you mean by "mass" is not what is meant in physics
by "mass". So your claim is unclear.

(a) What do you mean by "mass"? Be clear! An operational definition
would be good!

(b) Exactly what are you claiming has this "mass"?

Apart from that, you seem to think that whether or not E=hf is
relativistic is somehow relevant (it isn't), and that Planck having
suggested E=hf 5 years before Einstein's paper on special relativity
is somehow important (it isn't).

Post by Y.Porat

OK, so by "mass", you mean what modern physics means by "inertia".

So, you could harmonise your terminology with that of modern physics,
and use "inertia" instead of "mass", and be understood.

Do you know why modern physics distinguishes between "mass" and
"inertia"?

Consider the inertia of a photon. Take a photon of wavelength lambda
500nm. You can find the frequency, and the energy, and the momentum.
The momentum is p=h/lambda.

To adopt your definition of mass, we would say that the photon has
mass h/(c*lambda).

Now choose a coordinate system moving at 3x10^7 m/s in the same
direction as the photon. In this coordinate system, the wavelength of
the photon is approximately 550nm.

Calculate the "mass" (according to your definition of mass), and
compare. It's now about 10% less.

Does the mass of an object depend on our arbitrary choice of
coordinate system? According to your definition of mass, it does. If
you don't like that, you need a different definition of "mass". Modern
physics doesn't like that, and uses a different definition of mass,
that agrees more closely with the old Newtonian definition of mass.

(Your definition of mass has been used in physics, alonside a number
of other definitions of mass.)

GOT IT ??!
We can detect the colour "red". Does colour have mass? We can measure
the resting metabolic rate of a human. Does resting metabolic rate
have mass? We can detect tides. Do tides have mass? We can detect the
flight of bats? Does flight have mass?
No, that's not a clear definition at all.

in our case i dont mind waht it i s in other cases

for me if i see the Kilogram dimension in that
formula it is mass
now the dispute is only
whether it is relativistic or not

we cant go back to Adam and eve forever
so lest s stick to the question is the kilograms
(prvided that we are knowlagable enough to
know how a physics formula is built and used!!

Consider the inertia of a photon. Take a photon of wavelength lambda
500nm. You can find the frequency, and the energy, and the momentum.
The momentum is p=h/lambda.
-------------
right
Post by Timo Nieminen
To adopt your definition of mass, we would say that the photon has
mass h/(c*lambda).
hc/lambda is Momentum not mass
how did you got it ??
THE MASS IS HIDING IN THAT h
got it ?
----------------
Post by Timo Nieminen
Now choose a coordinate system moving at 3x10^7 m/s in the same
direction as the photon. In this coordinate system, the wavelength of
the photon is approximately 550nm.
-------------
why do you whant to obfuscate the issue

the
E=hf as found measured and defined
in just one fram that was standing still
got it
we discuss only that formula as it was foun
and defined

in that case
nothing (NOTHING !!) IN IT IS RELATIVISTIC
EVEN THOUGH THE PHOTONS THERE WERE MOVING AT c !!
**but the energy they emitted was
hf and nothing more than that !!!***

Calculate the "mass" (according to your definition of mass), and

one
some of them are not quick enough
(because they are limited by their c )

to neter the second fram that is running away from the first frame
so
THE ENERGY THAT ENTERED THE SECOND FRAME
IS NOT ANY MORE THE ORRIGINAL
ENERGY !!

yet all the addditional explaantion i gave it

nothing in the orriginal frame energy

Photon's in a Box.

If you released a one Kg pulse of light from the center of a mirrored
box it would not increase the gravitational mass of the closed system
at all, assuming a spherically symmetric light pulse.

It would temporarily increase the inertial mass of the box as the
external acceleration put upon the box would deform the spherical
symmetry of the pulse trapped within.

In time the pulse would be absorbed by the box and its quasi kinetic
energy would be converted into heat. Causing the gravitational and
inertial energies to resume their normal condition of equality.

When Max Planck originally derived E=hf he gave it as E=hf. He was
equating the total energy of emitted light and thermo-dynamic energy
of the matter in the light source so this is the correct scalar form.

If you assume the perspective of a frame of reference moving with an
individual photon then f falls to zero and E=h ergs, but no ergs per
second. If you assume the frame of a stationary observer then E=-hf.

Before it was created the photon had a certain thermal and dynamic
energy in the atom. Once emitted it carries this energy along with.
The apparent kinetic energy is highly dependent upon the frame of
reference of the observer. If it is absorbed - ie observed, then the
thermal energy recovered is influenced by any observer motion relative
to the source.

Critics will argue that the solar wind proves that light has a
positive momentum. The near solar wind is composed mostly of particles
with a measurable rest mass and thus a push. The photons do not, in
fact they pull!

This can be demonstrated by a correct understanding of photon
absorption. Photon's which are absorbed by electrons excite the
electrons. The effective orbital radius is incrementally increased
which reduces the electrons speed but increases its total energy.
(Orbital mechanics are complex and tend to work backwards of what we
tend to consider "normal". (Consider the spinning figure skater, arms
in = faster, arms out = slower, rotational energy arms in or out is
equal.)

In photon absorption the photon has "lifted" the electron to a higher
orbital, increasing its energy, but reducing its speed.

In photon emission the electron "falls" to a lower orbital. In doing
so it rips a hole in the fields of space-time (momentum) and electro-
magnetic (spectral lines and such) in order to maintain a net
thermodynamic equilibrium. These holes self propagate at a fixed rate
of c regardless of frame of reference.

The light from stars we have left behind will never catch up. Their
matter and energy are now dead to us.

We can reasonably infer that these stars once existed because the
ghost of their material presence is still observable to us as if a
"dark matter" that we calculate must have once existed is now gone and
their apparent demise further demonstrated by a "dark energy" that we
observe is causing our still observable universe to appear as if it is
expanding at an ever increasing rate.

We currently observe that these bygone stars nearer or speedier
cousins are in the process of red-shifting their way toward
observational oblivion and we can reasonably infer that this has been
going on for some time now.

What we observe clearly indicates that vast distance and or fast
relative motion cause apparently "real" changes in "real" mass, in
exactly the same relative way that these factors effect apparent
photon mass and energies.

To adopt your definition of mass, we would say that the photon has
mass h/(c*lambda).
hc/lambda is Momentum not mass
hc/lambda is not h/(c*lambda). In any case, h/lambda is the momentum
of a photon. If you disagree that, with your definition of "mass", h/
(c*lambda) would be the "mass" of a photon, what do you say it would
be?

Isn't it just a matter of your "mass" = E/c^2 = hf/c^2 = h*(f/c) * 1/c

No. E=hf works in all inertial frames.

Really, E=hf is irrelevant to this. Try the pre-quantum version then:

Take a pulse of light, collimated, of total energy 1J, with a spectrum
with central wavelength 500nm.

Energy is 1J, momentum is 1/3e8 kg.m/s, inertia in units of mass is 1/
(3e8)^2 kg.

Now choose a coordinate system moving at 3x10^7 m/s in the same
direction as the pulse. In this coordinate system, the central
wavelength of
the spectrum of the pulse is approximately 550nm, the energy is
approximately 0.9J, momentum is 0.9/3e8 kg.m/s, inertia in units of
mass is 0.9/(3e8)^2 kg.

In this coordinate system, the inertia is different. That's what _you_
want to call "mass". You think it's OK for the "mass" to depend on our
arbitrary choice of coordinate system? Modern physics has decided
"no", and what modern physics calls "mass" doesn't depend on our
choice of coordinate system.

When I say it isn't "relativistic", I mean that it isn't a "special
(or general) relativity thing". What do _you_ mean by "relativistic"?

The expression for kinetic energy from classical mechanics, KE =
(1/2)m*v^2 is generally agreed to not be "relativistic", again in the
sense that it isn't a special (or general) relativity thing. However,
it is very much dependent on our choice of coordinate system.

You say that what you mean by "mass" is "inertia", including for
photons. Experimentally, we find that this is dependent on our choice
of coordinate system. For light, specifically, this dates back to 1876
(Bartoli). For inertia of energy in general, it dates back to 1874
(Umov). It was implicit in Maxwell's results for radiation pressure
(1873 at the latest). Are you trying to claim that these results,
which predate special and general relativity by decades, are somehow
"relativistic"?

If so, you really need to explain what _you_ mean by "relativistic".

You've refused over and over to even try to define what you mean by
"mass", and then when you finally admit that you mean "inertia", you
refuse to discuss that, and instead focus on the entirely irrelevant
matter of whether E=hf is "relativistic".

Here is the non-relativistic, non-quantum version:

Take a pulse of light, collimated, of total energy 1J, with a spectrum
with central wavelength 500nm.

Energy is 1J, momentum is 1/3e8 kg.m/s, inertia in units of mass is 1/
(3e8)^2 kg.

Now choose a coordinate system moving at 3x10^7 m/s in the same
direction as the pulse. In this coordinate system, the central
wavelength of the spectrum of the pulse is approximately 550nm, the
energy is approximately 0.9J, momentum is 0.9/3e8 kg.m/s, inertia in
units of mass is 0.9/(3e8)^2 kg.

In this coordinate system, the inertia is different. That's what YOU
want to call "mass". You think it's OK for the "mass" to depend on our
arbitrary choice of coordinate system? Modern physics has decided
"no", and what modern physics calls "mass" doesn't depend on our
choice of coordinate system.

But YOU want to call it mass. Why not call it "inertia", and be
understood more easily? But whether or not you call it "mass" or
"inertia", that's a matter of nomenclature, not physics. Not a new
contribution to physics - physics has been there and done that,
discovered the problems with calling "inertia" "mass", and moved on to
more sound terminology).
i explained to you dumbo
what i smass for me and you keep on asking me what is mass

in one frame
No, that isn't what you said at all. You refused, over and over, to
explain what you meant, and when you did explain it, that wasn't your
explanation. I kept on asking you to explain because you kept on
refusing to explain.

That's something else entirely. You asked:

(a) Whether E=hf is relativistic - it predates relativity by years,
and it isn't relativistic; it's a quantum thing. Relativity is not the
same thing as quantum theory. This isn't anything new or surprising.

(b) You asked whether there is "mass in energy" (while refusing, over
and over, to explain clearly what you mean by "mass".

Whether or not (c) "E=hf is the formula of a single photon" is
about an entirely different (a) and (b)? Further, if you don't agree
with Planck's E=hf (as the quantisation of EM energy) - that is, you
don't believe that E=hf, then how can it be relevant whether E=hf is
relativistic?

Why change the subject to something irrelevant to the previous? If you
weren't interested in discussing the previous topic, why did you keep

Where we were at (apart from you refusing to state your position
clearly) was the non-relativistic, non-quantum version of the problem
(that it is non-relativistic shows that the question of whether E=hf
is "relativistic" is irrelevant, that it is non-quantum shows that
E=hf is irrelevant):

Take a pulse of light, collimated, of total energy 1J, with a spectrum
with central wavelength 500nm.

Energy is 1J, momentum is 1/3e8 kg.m/s, inertia in units of mass is 1/
(3e8)^2 kg.

Now choose a coordinate system moving at 3x10^7 m/s in the same
direction as the pulse. In this coordinate system, the central
wavelength of the spectrum of the pulse is approximately 550nm, the
energy is approximately 0.9J, momentum is 0.9/3e8 kg.m/s, inertia in
units of mass is 0.9/(3e8)^2 kg.

In this coordinate system, the inertia is different. That's what YOU
want to call "mass". You think it's OK for the "mass" to depend on our
arbitrary choice of coordinate system? Modern physics has decided
"no", and what modern physics calls "mass" doesn't depend on our
choice of coordinate system.

But YOU want to call it mass. Why not call it "inertia", and be
understood more easily? But whether or not you call it "mass" or
"inertia", that's a matter of nomenclature, not physics. Not a new
contribution to physics - physics has been there and done that,
discovered the problems with calling "inertia" "mass", and moved on to
more sound terminology).

If so, you really need to explain what _you_ mean by "relativistic".
You've refused over and over to even try to define what you mean by
"mass", and then when you finally admit that you mean "inertia", you
refuse to discuss that, and instead focus on the entirely irrelevant

--------------------------
why don t you   answer that Pigy
(i must say piggy because that  is exactly your behavior !!

the formula for   the real single photon or not ??
No, you didn't ask that. The above "so jsut give me some credit to
believe that (E=hf not the formula of a single photon!!)" is not a
question, at least as understood as a question in English. (If you did
ask that in your preceding posts, do quote exactly where, and I will
apologise that I missed it - I certainly saw no such question, but I
might have missed it in the less comprehensible parts of your posts.)

You didn't ask it; you just declared that it is so, with no evidence
or other any other support. You _claimed_ that you had shown it and
proved it, but you hadn't. No proof, no showing, no evidence. Not even
dealing with the ample contrary evidence.

You claimed, quite explicitly, that I was wrong when I stated "Whether
E=hf is relativistic - it predates relativity by years, and it isn't
relativistic; it's a quantum thing. Relativity is not the same thing
as quantum theory. This isn't anything new or surprising."

What's wrong? I said

(i) E=hf predates relativity by years. Is that wrong?

(ii) E=hf isn't relativistic. Is that wrong?

(iii) E=hf is a quantum thing. Is that wrong?

(iv) Relativity is not the same thing as quantum theory. Is that
wrong?

(v) That points (i)-(iv) above are not new or surprising. Is that
wrong?

You claim "wrong". Be precise - which of the above is wrong?

Also, we were discussing the non-relativistic, non-quantum version,
and you disagreed with my (approximate) calculations. Rather than just
insulting me, why not provide what you think are the correct
calculations? If I'm wrong, the correct calculation will produce a

Since you're refusing to answer any questions, refusing to even try to
clarify any of your points that remain unclear, and generally
descending into a psychopathic round of insults and lies, there
doesn't seem much point in continuing this.

However, I will give you another chance. Where we were at (apart from
you refusing to state your position clearly) was the non-relativistic,
non-quantum version of the problem (that it is non-relativistic shows
that the question of whether E=hf is "relativistic" is irrelevant,
that it is non-quantum shows that E=hf is irrelevant):

Take a pulse of light, collimated, of total energy 1J, with a spectrum
with central wavelength 500nm.

Energy is 1J, momentum is 1/3e8 kg.m/s, inertia in units of mass is 1/
(3e8)^2 kg.

Now choose a coordinate system moving at 3x10^7 m/s in the same
direction as the pulse. In this coordinate system, the central
wavelength of the spectrum of the pulse is approximately 550nm, the
energy is approximately 0.9J, momentum is 0.9/3e8 kg.m/s, inertia in
units of mass is 0.9/(3e8)^2 kg.

In this coordinate system, the inertia is different. That's what YOU
want to call "mass". You think it's OK for the "mass" to depend on our
arbitrary choice of coordinate system? Modern physics has decided
"no", and what modern physics calls "mass" doesn't depend on our
choice of coordinate system.

But YOU want to call it mass. Why not call it "inertia", and be
understood more easily? But whether or not you call it "mass" or
"inertia", that's a matter of nomenclature, not physics. Not a new
contribution to physics - physics has been there and done that,
discovered the problems with calling "inertia" "mass", and moved on to
more sound terminology).

If you can't explain your position and argument clearly and
coherently, how will anybody know you actually have one? How will
_you_ know you have one?

other readers saw and understood it
so my question is just that

did you ever saw that before

Insults, no evidence, and this is irrelevant to the previous
discussion about mass (the topic of the thread, and also what we were
discussing). That you have a fantasy about what science calls
"photons" being composed of billions and billions of what you call
"photons" is old stuff. And you just repeat that claim with no
coherent evidence. And irrelevant as to what the "mass" (as you wish
to call it) or inertia of that E=hf energy is.

''photons changing their energy while entering a secondary frame''. Do
you need me to explain to you what a coordinate system is? Do you need
me to explain to you how the photon exists in both coordinate systems
being considered, at the same time, and doesn't leave one and enter
the other. I can also explain that the photon doesn't change energy -
as measured in either coordinate system, the energy of the photon
stays the same (and is given by E=hf).

Where we were at (apart from
you refusing to state your position clearly) was the non-relativistic,
non-quantum version of the problem (that it is non-relativistic shows
that the question of whether E=hf is "relativistic" is irrelevant,

you begine t o cheat AND OBFUSCATE Mr Nimo
if E=hf was found to be right
as not relativistic
in just one frame
then is it relativistic ??
E=hf
is not relativistic
do you want now to deny that you agreed about it ??
When I say it isn't "relativistic", I mean that it isn't a "special
(or general) relativity thing". What do _you_ mean by "relativistic"?
The expression for kinetic energy from classical mechanics, KE =
(1/2)m*v^2 is generally agreed to not be "relativistic", again in the
sense that it isn't a special (or general) relativity thing. However,
it is very much dependent on our choice of coordinate system.
You say that what you mean by "mass" is "inertia", including for
photons. Experimentally, we find that this is dependent on our choice
of coordinate system. For light, specifically, this dates back to 1876
(Bartoli). For inertia of energy in general, it dates back to 1874
(Umov). It was implicit in Maxwell's results for radiation pressure
(1873 at the latest). Are you trying to claim that these results,
which predate special and general relativity by decades, are somehow
"relativistic"?
If so, you really need to explain what _you_ mean by "relativistic".
You've refused over and over to even try to define what you mean by
"mass", and then when you finally admit that you mean "inertia", you
refuse to discuss that, and instead focus on the entirely irrelevant
matter of whether E=hf is "relativistic".
To Porat, something is relativistic if someone can point to a variable
and say "This is relativistic mass" or if there is a gamma factor in it.

He believes that a theory should be recognizable by certain variables
that appear in all its equations.

For example, he possibly also believes that an equation is recognized as
belonging to quantum mechanics if it has an h in it.

Let f = 1E+16 thus 'a photon' has hf energy or 6.63E-18 J.  We have
'a box' that weighs precisely 1 kg empty.  We add 1.36E+34 photons
to that box, what does it now weigh?  If photons are, if fact,
massless, should it not be still precisely 1 kg? :)
To repeat what I already wrote earlier in this thread, "photons are
massless" means that photons have zero rest mass. Rest mass is the
magnitude of the energy-momentum 4-vector.
The E-M 4-vector is P=(E/c^2,p_x,p_y,p_z). (That's the contravariant
vector - the covariant vector is neater, = (-E,p_x,p_y,p_z).) In
general, rest mass is m = |P|, in appropriate units (and sign,
m = sqrt(E^2/c^4 - |p|^2/c^2).
For your 1kg box, stationary, P_box = (1kg,0,0,0). If we add 9e16J of
EM radiation, stationary (i.e., in a bunch of standing wave modes in
the stationary box, on average), this has P_rad = (1kg,0,0,0).
The total E-M 4-vector is then P_total = (2kg,0,0,0). From which the
rest mass of the system (box + contained radiation) is 2kg.
(E=hf is entirely irrelevant in the above, unless you want to count
photons. All of the momentum/mass/energy stuff follows purely from
classical (i.e., non-quantum) considerations.)
But wait! It gets better!
Consider a collimated pulse of light, of energy 9e16J. This has
momentum p=E/c (collimated, so we can assume the energy-momentum
relation for a plane wave is good). Let us assume it is travelling in
the x-direction.
The 4-vector is P_collimated = (1kg,3e8N.s,0,0). The magnitude is
zero; rest mass of the collimated pulse is zero.
Now consider a spherically symmetric expanding pulse, of energy 9e16J.
Every point on the surface of the expanding pulse has some momentum,
directed outwards. Due to the spherical symmetry, the total momentum
is zero.
So, P_spherical = (1kg,0,0,0), and the rest mass of the spherical
pulse is 1kg.
Gravity is in play - momentum is not constant.

Ponder the above results for what is effectively a plane EM wave, and
a spherical wave. We see the statement that "photons are massless",
i.e., have zero rest mass. We also see (single) photons being defined
(i) Massless photons are plane wave photons.
(ii) The rest mass of a system is not the rest mass of its components
(follows directly from m = sqrt(E^2/c^4 - |p|^2/c^2, since E is
scalar, and p is a vector quantity).
Is there a rule that says a scalar + vector = scalar? Are you making that up?
Post by Timo Nieminen
(iii) For non-plane wave radiation, we can add a bunch of plane wave
modes. To obtain a standing wave in a box, with a total of a single
photon, that's a half-photon going one way, and a half-photon going
the other way - the usual recipe for non-zero rest mass.

Do you think that one of the above terms is not a scalar? If so,
review your vector properties. If v is a vector, |v| is a scalar.

WHAT IS RELATIVISTIC IN

That wasn't what you asked! You asked "just tel  us loud and clear do
photons have mass or not ??" Which is why I answered a question about
photon mass. I wrote a lot since I've answered the same question from
you before, and since you ask again, I must assume that you didn't
understand the answer the last time around.
But since you didn't like the answer to that question and now ask a
_completely_ different one: nothing. That is, there isn't anything
relativistic in E=hf. Is there supposed to be? Relativity is not a
quantum theory; quantum theories are not necessarily relativistic.
--------------------
please tell us loud and clear and SHORT !!!
what is the mass in E=hf  ( mind you it is energy !!! ---energy!! and
it means a lot !!! )
It doesn't have any mass in it. E=hf is about _energy_, not _mass_.
These are different things. There are accepted technical usages of
these terms, with narrow, well-defined meanings. E=hf doesn't have
what physicists mean by "mass" in it. I don't know what _you_ mean by
mass, because you haven't said. Will you say? Below, I ask.
Post by Y.Porat
so
is it
relativistic  mass or not  relativistic mass
ie just mass  the only mass !!??
BTW

E=hf has mass in it ??!!
I know you keep saying that E=hf "has mass in it". That's why earlier,
I wrote the paragraphs below. Basically, you are using a _different_
definition of mass from that used in modern physics (and it's also
different from Newton's definition).
What is your definition of mass? Be clear! You can be loud and short
if you wish, but _clear_ is essential!
"Second, I know you don't like the idea of "rest mass", "relativistic
mass", etc., what with your "one kind of mass" line. A whole bunch of
physicists also agree that "one kind of mass" is the way to go, and
therefore have decided that "mass" should always mean "rest mass". If
you want a good word for what was once called "relativistic mass", try
"energy". It's cohesive and complete: "mass" (i.e., rest mass) is the
magnitude of the energy-momentum 4-vector, "energy" is the time-
coordinate-axis component of the energy-momentum 4-vector, and
"momentum" is the 3 spatial components.
Earlier, "mass" was used rather ambiguously (and still is in some
writing). But don't be confused by that! The modern statement that
"photons have no mass" refers unambiguously to rest mass!
Third, in light of the above, you had better clarify just what kind of
"mass" _you_ mean with your "one kind of mass", if you want other
people to understand you. How about (a) and operational definition of
_your_ mass, and (b) include an operational definition of your mass
for moving objects."
----------------
again you talk a lot and do not answer simply:

i dont mind and we dont need the philosophy about mass
because we can make it much simpler

so i will stick at this stage to the formality of it
so i will ask you :

if yes
what is there to multiply it(the mass unit) or any of the other

Define "the** mass unit** entity"!

I can try to guess what you mean (and if this is wrong, you need to go
back and _clearly_ define what you mean by "mass unit entity", which
might require you to define mass, which for some reason, you keep
refusing to do).

Via the work-energy theorem, we can see that the units of energy are
(units of force)*(units of length).

From Newton's 2nd law, (unit of force) = (unit of mass)*(unit of
acceleration) = (unit of mass) * (unit of length) / (unit of time)^2.

So, we have (unit of energy) = (unit of mass) * (unit of length)^2 /
(unit of time)^2.

This has nothing to do with E=hf; this is just ordinary classical
mechanics. Does energy "contain" mass because the units of energy can
be written in terms of units of mass (and other quantities)? You might
as well ask "Does energy contain area?", since there's (unit of
length)^2 there, too.

In SI, I can also write [J] = [C]*[V]. Does energy contain electric
charge?

Or, to write it more breifly since the above slides off your mind like
water off a duck's back:

(A) THE UNITS OF ENERGY CAN BE WRITTEN IN TERMS OF UNITS OF MASS,
LENGTH, AND TIME. THIS DOESN'T MEAN THAT ENERGY "CONTAINS" MASS, OR
LENGTH, OR AREA, OR TIME.

(B) THIS HAS NOTHING TO DO WITH E=hf, WITH RELATIVISTIC STUFF, OR WITH
QUANTUM STUFF - THIS IS JUST ELEMENTARY CLASSICAL MECHANICS. IT ALSO
HAS NOTHING TO DO WITH THE MASS OF PHOTONS.

Such a strange question! Does energy (the units of which I can write
in terms of units of charge) contain relativistic charge or
socialistic charge? Does energy contain relativistic area or
socialistic area?

Simply put, energy doesn't contain mass, so asking whether _any_
energy, whether the E in E=hf, or some other energy, contains
relativistic mass or the "one true mass" (which you keep refusing to
define) is simply nonsense! Does your television contain green people
or purple people?

This has _nothing_ to do with E=hf.

Ah, well. Maybe if we think in terms of elementary QIT. Energy is
an information carrier and at the quantum level, anyway, information content of
a volume is bounded by the area of the region, not its volume.
Dimensional analysis can be dodgy at the best of times I will admit,
but just maybe there is some kind of "Just So" explanation for that

A suggestion in keeping with much of the rest of the argument in this
thread: use "mass" to mean the invariant mass, a.k.a. the rest mass.
Use inertia to mean inertia, use energy to mean energy. Follow modern
usage and throw away terms like "relativistic mass".

Then you needn't be offended by "90% of the proton mass is due to
relativistic mass of gluons" etc., and you can have instead "90% of
the proton mass is due to the energy of gluons". Better, yes?

now Timo
dont you see that we did just above
History of physics ??!!
hf ie Enrgy
DOES NOT HAVE RELATIVISTIC MASS!!
overgeneralise below!
-----------------------------------
the trouble is that you dont understand what you yourself was
talking and agreed !!!!
if you agreed that
E=hf has nothing relativistic
you said all of it !!!
because
E is eenrgy of photons !!
AND PHOTONS ARE EM WAVES!!
AND EM WAVES ARE ENERGY !!!!
GOT IT
EM WAVES ARE ENERGY !!
SO IF EENRGY HAS NOTHING RELATIVISTIC IN IT
THEN IT HAS MASS IN IT
NOW
PARROTS SAID AL ALONG THE 20TH CENTURY THAT
EENRGY HAS MASS!! BUT ITISNOT REST MASS
BUT' RELATIVISTIC MASS'
again the common claime was
'energy has mass
'but it is 'relativistic mass'
yet jsut above we proved that
the Planck experiment that discovered the
energy of photons as
E=hf
***has nothing relativistic in it **
you cant say anymore that
EM waves** has** 'relativistic mass
THERE IS SOME KIND OF MASS
IN EM WAVES !!

while we proved and showed just above that
THERE IS NOTHING AGAIN NOTHING!!
IN THE ENERGY OF PHOPTON THAT IS RELATIVISTIC
SO IF NOTHING IN IT IS RELATIVISTIC!!
THEN EVEN THE MASSIN IT
IS NOT RELATIVISTIC !!
do you uderstand the meaning of
''noting in it '??!!!
nothing in it includes the thing that is called mass
insimpler words
themass in E=hf is not relativistic
and if not relativistic it is rest mass

the MKS system has just one KILOGRAM in it
thereis no
K1 k2 k3 kilogram
unless
listen carefully

UNLESS-
there i is in a formula SOMETHING
A SCALR THAT IS
MULTIPLYING IT BY SOMETHING RELATIVISTIC

BECAUSE
E=hf HAS NOTHING IN IT THAT
MULTIPLY IT AS A RELATIVISTIC SCALAR
and jsutly so !!
because in the Planckexperiment there was nothing relativistic
IT WAS FOUND AND DEFINED 5 YEARS
BEFORE sr WAS BORN!!
MOREOVER:
ALL THE TOLS USING TO FIND IT
AND MEASURING TOOLS FOR IT
WERE IN A **STAND STILL** SITUATION!!
it is not a mathematical issue
it is a physical issue !!!
physical facts involved with it and how it was derived
so again
YOU CANT GET CAMEL MILK FROM A COW!!
iow you cant get something that is only in your imamgination or
private wrong interpretations
while it does not exist physically and even formally !!
now let me explain something that didnt have to
say and explain to veryfy my above histiric finding !!iow
i proved it even without what i am going to say
following
what is confusing people here is

''NO MASS CAM REACH c''
the idiotc mathematical 'prove' for it was
that while you take the gamma factor

Gamma = 1 /squarute (1-v^2/c^2)
then while v=c
becomes infinite !!!

but the idiots didnt noticed that infinite
IS AN UNDEFINED SITUATION
EVEN MATHEMATICALLY !!
so you cant reffere from it your private
beliefs !!
and fish in the dirthy water as you like it !!
because there are other alternatives
in that vague that are differnt from yours
like
THE PHOTKN IS AN EXCEPTION TO THE RULE THAT NO MASS** CAN ** REACH
c !!
(yes we can said Obama lately (?:-)

because it is a limit case that is not defined mathematically
AND YOU CANT GET CAMEL MILK FROM A COW !!!
while jsut above we proved that
there is nothing relativistic in
E=hf
that you Nimo
justly agreed just above !!!
(you had no choice as an
intelligent honest mas
--but to agree with it ) !!

so believe it or not:

we did some history of physics just above !!!

because its meaning and goes **far beyond**
much further than you can imagine just at this moment !!

thatis not what   20 The century 'mpdern physics'
was pumping unjustly all laong
with billions of \$ wasted on it
as virtual aprticles without mass but relativistic mass
90 percent of Proton  mass done
by 'relativistic mass of Gluens    etc etc
A suggestion in keeping with much of the rest of the argument in this
thread: use "mass" to mean the invariant mass, a.k.a. the rest mass.
Use inertia to mean inertia, use energy to mean energy. Follow modern
usage and throw away terms like "relativistic mass".
Then you needn't be offended by "90% of the proton mass is due to
relativistic mass of gluons" etc., and you can have instead "90% of
the proton mass is due to the energy of gluons". Better, yes?

Take a box full of photons.
Gravity - Photons pick up energy as they head down and so the ones at the bottom exert more pressure at the bottom
than the top - same as weight/mass
Inertia - Accelerate the box and we blueshift the photons at the back and redshift the front ones - more pressure
at back than front - inertia.
Photons have no mass but........................
Mr Forbes
it seesm that you stole some idea
but you sto;e it not good enough
see my 'Circlon idea'
it is not exactly photons
photons are different than the 'Circlon'
yet might be  'cousins ' .....

I stole northing - this is just something that occurred to me and I thought I'd post it and see the response. I do
not claim that it's original or anything else - it's pretty straight forward really based on what's already known.
