Back before everyone began to worship Einstein's sphincter science and
invention, especially IMPORTANT inventions and science that greatly
changed the way every one lives and looks at the world, used to hold up
the practical persistence of Edison and the brilliant inspiration of
Tesla as examples.

But then came Einstein and everything changed. Suddenly the measure of
science was not how practical you could make it in everyone's life but
rather how incomprehensible you could make it. The bigger the snow job,
the "higher" and "more advanced" the science was thought to be. The
measure of a scientist was no longer their discoveries of how Nature
worked as in the 19th century days of "Natural Philosophers" but rather
how obscure your mathematical derivations were. Science turned on it's
head.

And oddly Einstein himself took the opposite viewpoint asserting that
advanced physics could be explained to a barmaid if you understood it.

Professor Armstrong of Columbia University wrote about this in an article:

"The student picking up a textbook... does not get this picture. He
finds, instead a series of mathematical expressions almost totally
divorced from any basis of physical reasoning. He gets the impression
that he must learn to think in terms of trigonometrical functions, reams
of calculations and tables of all sorts. Nothing could be more
fantastic... the impression has been created that in some magical way
invention is connected a bewildering maze of symbols and curves."


Thank you Einstein! And you see it here in a host of paul drapers and
others worshiping Albert's sphincter and assuring everyone that science
is really all about a semantic debate over words and that mathematics is
more real than reality.

What does Einstein have to do with the mathematisation of classical mechanics? Blame Galileo and Newton for that.

"The laws" = math.

I don't know what the quote has to do with classical mechanics. Unless
you are saying that Galileo and Newton started the worship of
mathematics as reality that was finished by the worshipers of Einstein.

Of course Newton did help with that by inventing his own mathematics to
go with his philosophy. Galileo, not so much. I find it interesting that
time and again one hears that "Newton explained gravity" especially
among popular science press, though not exclusively limited to them. And
of course nothing could be further from the truth. Newton modeled
gravity forces in mathematics but explained nothing (except for his
"corpuscle" theory). Indeed Einstein did likewise where curvature of
space-time models gravity but nothing is "explained".

But hey, let's give old Galileo credit! Way back in the dark ages he
actually came up with the principle of relativity (in relation to
mechanics) which later Einstein and others asked the salient question:
Does Galileo's principle ALSO apply to electromagnetics (many suspected
it did) and the rest is history! And Galileo didn't have to "curve
space-time".

Note that I'm not saying that mathematics is useless or not an
interesting and important endeavor, only that it is fantasy and not
reality so far as we know. Though many here have asserted that
mathematics is the ONLY reality!

They (and many of their predecessors and contemporaries) started the primacy of mathematical models in physics. Galileo also pushed the idealised thought experiment quite strongly.

I haven't read the original source of the quote (the 1944 article), so I don't know what students Armstrong refers to. If he's writing about beginning students, he's talking mechanics, not EM theory. He is just talking about classical theory.

The relevance of your quote to that? Armstrong is complaining about over-dependence on "thinking in mathematics". That is, using mathematics as the tool to get results rather than physical reasoning.

over-dependence on "thinking in mathematics". That is, using
mathematics as the tool to get results rather than physical
reasoning.
The students Armstrong is talking about were likely Electrical
Engineering students of the 1930s and 1940s. (Math and engineering were
rather different then...note his reference to plots and charts)

However his beef, is relevant, which was the worship of mathematics as
more real than reality. Professor Armstrong had invented what is
essentially modern FM radio as a solution to all the problems of the
then standard AM broadcasts. The hassle he found (and what set him off)
was that people had already used mathematics to "prove" that FM was an
unworkable system and virtually everyone to a man in the field was
convinced that Armstrong's invention was nothing more than
pseudo-science and quackery.

Demonstration after demonstration made few inroads on the belief because
the trust in mathematics being more real than reality was so strong (and
of course there were political aspects of corporations with
self-interests in keeping the status quo)

And you can see that nothing has changed just by going down a list of
science "forbidden topics" and charges of quackery and "pseudo-science"
immediately ensue because why? Because of data? Nope that's simply
dismissed out of hand as if it never happened. It is claimed to be
"fraud" or "incompetence" and so on. Nay, what is accepted as the
ultimate proof positive of quackery is the mathematical calculations!

In other words fantasy is the accepted proof of whether or not something
is real!

No. Nothing about "real" in the quote. Just about how to go about getting results. He's complaining about over-dependence on mathematics in coming up with ideas and results. Nothing to do with your philosophy of the (un)reality of mathematics.

Not exactly guessing but I have not read the original. Story is I
encountered the article reference in working on another (unrelated)
piece by a different author. He suggested that Armstrong committed
suicide because of the extreme resistance to his views on science and
mathematics (a conclusion I think is rather over reached). But didn't
give the reference to the article. I found that the Armstrong biography
had his bibliography in it so I bought it for the reference. The Bio
included the quote from the article and a brief description of the
events surounding it. That's what I know. The quote speaks for itself.

Note you are trying to pretend that this needs to be some kind of
irrefutable prove of my premise and that since it's not, I lose.

Sorry, this was only one nail in the coffin of math more real than
reality, not a proof of itself. You need to move on to my next post
with the quote from Einstein in which he characterizes geometry as fantasy.

The difference here between you and Armstrong is that you feel that
somehow math reflects the underlying wheelwork of nature. Therefore if
one does enough math and comes up with a prediction based upon that math
all that is then needed is to go measure the prediction, verify that the
math indeed was correct in the prediction et voila! It's another huge
success for math as the underlying basis for all reality.

Armstrong takes the opposite view, namely that while not denying the
above can work it is ALSO true that math can predict things that prove
totally false when measured. Hence the mathematics is NOT a
representation of the underlying wheelwork of nature but just a tool to
quantify results ONCE the person has a philosophy that seems to reflect
how nature works down in the wheelwork. In other words nature is real,
but mathematics is not.

As Einstein notes the reason math cannot represent reality is because it
is not based on reality at all. The idea is stupid. Math is based only
on self-consistency. The "truth" of the beginning postulates is not even
a question that makes sense.

Yes, the book by Lawrence Lessing.

Lessing didn't say that. He committed suicide because of legal issues
surrounding payment for his work on FM radio. In his suicide note, he
expressed deep regret for his physical attack on his wife and her
leaving him as a result, and that physical attack had been prompted by
her begging him to give up the lawsuits and move into retirement, both
of which he could not do.

The context of the quote was given in the book, but which you

Einstein did not say geometry was a fantasy. Please pay attention to
what you read. Einstein said, "But my dear boy, mathematics proves
nothing." That is not saying that geometry is a fantasy.

There are also physical concepts attached to the math. That is what
makes it a physical theory. And yes, if you use the concepts and the
math to come up with a prediction, and then you go MEASURE the
prediction, verify that the prediction was correct, then absolutely yes,
it's a huge success for the physical concepts and the attached math as
the underlying basis for reality. That is how science works, exactly.

Yes, and if that's the case, then THAT THEORY is shown not to be a
correct representation of reality.

It does not show, however, that all mathematics is
therefore invalidated as an accurate model of reality. You have this
really goofy idea that if a mathematically supported idea is shown by
measurement to be not representative of reality, then ALL of mathematics
is therefore discountable as fantasy.

The difference here between you and Armstrong is that you feel that
somehow math reflects the underlying wheelwork of nature.
Yesterday, I was talking about existence/uniqueness proofs concerning solutions to a particular problem with another physicist, following his conference presentation in which he mentioned it. I said that I'm satisfied with (a) an existence argument based on physical reasoning, and (b) a uniqueness argument based on computational reasoning. He said that neither is "proof". Sure, neither is proof, but they are enough for me to proceed. He would like proof (but he also proceeds).

While he was certainly more mathematically inclined than me, did he think mathematics is more real than reality? To quote from a book of his: "However, as we have mentioned in section [...], [foo] is not a real physical phenomenon, albeit it can be a useful mathematical abstraction."

Meanwhile, you will look at a mathematical description of the electromagnetic field, see three different terms in the maths, and proclaim that therefore there are three physically real EM fields.

Don't project your sins of falling for the "reality of mathematics" onto others!

utter nonsense. It needs saved for some political debate.

Point is: Sometimes mathematics seems to model the actions of nature
quite nicely and when it does it's rather useful in making predictions
to be tested and expanding understanding of the phenomena.

But there is NO requirement that math reflect nature. Indeed since math
is fantasy, I can at any time imagine a new mathematical system the
polar opposite of the one reflecting nature that is GUARANTEED to be
wrong! Such a system has no value for science or prediction. But that
does not make it mathematically invalid and not of interest to
mathematicians. In fact, many mathematicians revel in such systems proud
of the fact they have no utility!

Have you read the original article, or are you guessing?
Not exactly guessing but I have not read the original.
"Not exactly"? How do you know, if not by guessing?

The difference here between you and Armstrong is that you feel
that somehow math reflects the underlying wheelwork of nature.
Yesterday, I was talking about existence/uniqueness proofs concerning
solutions to a particular problem with another physicist, following
his conference presentation in which he mentioned it. I said that I'm
satisfied with (a) an existence argument based on physical reasoning,
and (b) a uniqueness argument based on computational reasoning. He
said that neither is "proof". Sure, neither is proof, but they are
enough for me to proceed. He would like proof (but he also
proceeds).
While he was certainly more mathematically inclined than me, did he
think mathematics is more real than reality? To quote from a book of
his: "However, as we have mentioned in section [...], [foo] is not a
real physical phenomenon, albeit it can be a useful mathematical
abstraction."
He said neither is proof! Nobody, me included, is arguing here that
mathematical abstraction is not useful and should be rejected as tool.
The problems come when the opposite occurs. You see people (at times
even me) blandly dropping assertions including "infinity" and "points"
and a whole host of other non-real, imaginary, fantasy. Yes, we are
supposed to "fill in the blanks" and know what they mean...but when you
do it enough you start to forget that and assume that "dimensionless
objects" (points) or "infinity" actually are real things.

Meanwhile, you will look at a mathematical description of the
electromagnetic field, see three different terms in the maths, and
proclaim that therefore there are three physically real EM fields.
There really are NOT EM fields. Fields are mathematics and NOT real!
There are real electromagnetic FORCES and we use the mathematics of
"fields" to attempt to describe them. The fact that so many now think
that EM fields are somehow "real things" shows the danger of assuming
math is more real than reality.

Don't project your sins of falling for the "reality of mathematics" onto others!
How is it that when I've been the one pointing out the dangers of
thinking math is "more real than reality" your argument is that *I* am
the guilty one and am merely "projecting" my sins onto others. This is
utter nonsense. It needs saved for some political debate.
Point is: Sometimes mathematics seems to model the actions of nature
quite nicely and when it does it's rather useful in making predictions
to be tested and expanding understanding of the phenomena.
But there is NO requirement that math reflect nature. Indeed since math
is fantasy, I can at any time imagine a new mathematical system the
polar opposite of the one reflecting nature that is GUARANTEED to be
wrong! Such a system has no value for science or prediction. But that
does not make it mathematically invalid and not of interest to
mathematicians. In fact, many mathematicians revel in such systems proud
of the fact they have no utility!
Ben I agree with your point of view, your perspective, and all that.
Math is just another Language, I get it. Those that don't... well youKnow.

That we have a mathematical description of <foo> does not mean that <foo> is real. But having a mathematical description of <foo> doesn't mean that <foo> is mathematics and not real. I have a map of Marseille, but it seems that Marseille still exists. And is usefully described by the map!

math is more real than reality.
The two main possibilities:
(a) EM fields are a mathematical convenience for describing EM forces (as is possible from the operational definition of E and B from the Lorentz force law).
(b) EM forces are produced by fields (i.e., EM fields have real existence).

So, are EM fields real? We don't know for sure. What we do know for sure is that if EM fields don't exist, then energy isn't conserved (nor momentum, nor angular momentum).

Still, despite such issues with conservation laws, an agnostic approach is logically justifiable. No such wishy-washy attitude for you, though. Just a convinced proclamation that "EM fields are not real". That's a statement of fact that you're making - where is the evidence that EM fields are not real?

There is a requirement that our mathematical descriptions of nature reflect nature. Otherwise they're not very good descriptions. Whether first-principles theory or phenomenological models, mathematical models/descriptions of nature reflect nature.

Yes, one can have maths that doesn't reflect nature, but that's irrelevant when we're talking about using math to describe nature. There are animals that aren't dogs, but that doesn't stop dogs from being animals.

Well, yes, but both a map of Marseille and the City of Marseille are

Memorize the city map. In this case is your mental image of the city
real? It certainly is useful to find your way around. But if I begin to
think that my mental map is more real than reality, then I could assume
that if I CHANGE the map in my mind (which would still be a perfectly

In science we short circuit such nonsense by demanding that the mental
map be regularly checked with the actual city (experiment) and those
maps that don't match be thrown out.

they "produce". So indeed EM fields are all Force Fields. So where do
these forces come from? Who knows? But to turn it around and say that
there is this imaginary thing we call a "field" which CAUSES the forces
sort of has the cart before the horse, n'est-ce pas?

When you say EM fields "don't exist" you seem to be implying that they
are therefore zero or null. Which is not the case here. We can say that
Tinker Bell does not exist (in material reality) yet she most certainly
has properties and qualities that are widely known. Its a fine point.

Where are the measurements of EM fields that DO NOT involve measurement
of forces?

Suppose I stand in a field where a wind is blowing. I have a certain
cross-section we will call "q" and that interacts with the wind to
produce a force on me that I feel. I can walk all over that field
measuring the force I feel and produce a map of the forces. I can say
there is some kind of "field" out there that produces the force and we
can term that "field" some letter say "E". Hence the force on my butt is
easily described anywhere on that plot of land by the equation F = qE!

Now. I am a "real" object. The Wind is a real object. The force I feel
is certainly a real "action". but what about that "field"? Where is it's
"reality"? It's just one more Tinker Bell! To think that there is this
mysterious object, the "field", hovering all over that land that is
creating forces on people is just pure fantasy. It explains nothing.

Don't agree. Three FORCES are real! The fact that they have different
characteristics means they are different and not the same. We certainly
DESCRIBE the actions of these forces by maths so we can talk about what
they do. But are the maths real objects? Maths are NEVER real objects
because they have no connection to objective reality. Einstein himself
said so! Are you claiming you are smarter than Einstein? :-)

There are animals that aren't dogs, but that doesn't stop dogs from

But once you admit that maths are NOT more real than reality, and accept
that some animals are not dogs, then no matter how many dogs you observe
that are animals, you are NOT permitted to say that all animals are
dogs. Arguing that you've observed many animals and all were dogs means
nothing. it only takes ONE hippopotamus to crash your whole dog-animal
theory.

And even worse, the fact that your maths may or may not reflect reality
casts serious doubt on all those cases you collected where it SEEMED
that the maths reflected reality. But what if you weren't careful enough
and made a mistake. Perhaps one of the erroneous maths crept in when you
weren't looking? So admitting that not all maths reflect reality now
throws the WHOLE mathematic structure into doubt which was built up on
the assumption that maths did reflect reality!

If you say well, the mathematical models that reflect nature, certainly
all reflect nature, that may be a true statement, but it's not very
enlightening!

The maths can be written in a book. The book would be real. Would that make the maths real? Does having the map - the information - printed on a paper map make it real? What about an electronic map? Don't get hung up on the reality of the piece of paper on which the information is stored.

(The map vs city is not the case we have in science; the city can (and does) change in ways that require the map to be changed, but at any time, we can know we have a correct map. When we change the math map in science, it's because we learn more. The original map was defective, and we fix it, rather than the universe deviating from our original map.)

Meanwhile, you will look at a mathematical description of the
electromagnetic field, see three different terms in the maths,
and proclaim that therefore there are three physically real EM
fields.
There really are NOT EM fields. Fields are mathematics and NOT
real!
That we have a mathematical description of <foo> does not mean that
<foo> is real. But having a mathematical description of <foo> doesn't
mean that <foo> is mathematics and not real. I have a map of
Marseille, but it seems that Marseille still exists. And is usefully
described by the map!
Well, yes, but both a map of Marseille and the City of Marseille are
real objective objects.
The maths can be written in a book. The book would be real. Would that make the maths real? Does having the map - the information - printed on a paper map make it real? What about an electronic map? Don't get hung up on the reality of the piece of paper on which the information is stored.
Post by benj
But if we alter that slightly and have you
Memorize the city map. In this case is your mental image of the city
real? It certainly is useful to find your way around. But if I begin to
think that my mental map is more real than reality, then I could assume
that if I CHANGE the map in my mind (which would still be a perfectly
valid mental map, mind you) that therefore the CITY should change with a
new layout to match my new map.
Then you would be an idiot. And if you think that's what is done with mathematical models in science, you are an idiot. If you say that's what done with maths in science you are an idiot or dishonest. So, is there any relevance in your point?
Post by benj
In science we short circuit such nonsense by demanding that the mental
map be regularly checked with the actual city (experiment) and those
maps that don't match be thrown out.
Yes. So your complaints about maths being assumed to be more real than reality are baseless. (The map vs city is not the case we have in science; the city can (and does) change in ways that require the map to be changed, but at any time, we can know we have a correct map. When we change the math map in science, it's because we learn more. The original map was defective, and we fix it, rather than the universe deviating from our original map.)

There are real electromagnetic FORCES and we use the mathematics
of "fields" to attempt to describe them. The fact that so many now
think that EM fields are somehow "real things" shows the danger of
assuming math is more real than reality.
The two main possibilities: (a) EM fields are a mathematical
convenience for describing EM forces (as is possible from the
operational definition of E and B from the Lorentz force law). (b) EM
forces are produced by fields (i.e., EM fields have real existence).
So, are EM fields real? We don't know for sure. What we do know for
sure is that if EM fields don't exist, then energy isn't conserved
(nor momentum, nor angular momentum).
"Don't know for sure", is doubtless the correct answer. But if we ask,
"how do we measure fields?" the answer is that we measure the forces
they "produce".
No. We measure other things. Like the position of a needle we assume is moved by the magnetic field we assume is produced by a current we assume is produced by the electric field we claim to measure. But we call it a "voltmeter", not a "needle position meter".
Post by benj
So indeed EM fields are all Force Fields. So where do
these forces come from? Who knows? But to turn it around and say that
there is this imaginary thing we call a "field" which CAUSES the forces
sort of has the cart before the horse, n'est-ce pas?
We don't say that it's "imaginary". We have an operational definition in terms of the Lorentz force, and existence of the fields is a matter of philosophy. YOU are the one who states fields ARE imaginary. IMO, the arguments on conservation of energy are strong, but a decision based on them is still provisional.
Post by benj
When you say EM fields "don't exist" you seem to be implying that they
are therefore zero or null.
Above, no. My "not exist" above (which I don't believe is the case) is that the fields are merely a mathematical convenience.
Post by benj
Which is not the case here. We can say that
Tinker Bell does not exist (in material reality) yet she most certainly
has properties and qualities that are widely known. Its a fine point.
Post by Timo
Still, despite such issues with conservation laws, an agnostic
approach is logically justifiable. No such wishy-washy attitude for
you, though. Just a convinced proclamation that "EM fields are not
real". That's a statement of fact that you're making - where is the
evidence that EM fields are not real?
Where are the measurements of EM fields that DO NOT involve measurement
of forces?
Irrelevant. If we assume that energy is conserved, then either EM fields exist, or energy is carried from place to place by magic pixies or somesuch (which seems to be a much more bizarre assumption than EM fields).
(a) energy is not conserved
(b) energy is carried from point to point by magic
(c) energy is carried from point to point by <fill in the blank>
I choose "magic" given that HOW energy is carried is not known and
fields don't exist as real objects. Note that energy (according to
Maxwell and refuted by no one since) can ONLY be carried by A. Waves in
a medium. or B. Particles with kinetic energy. In an EM case NEITHER can
be true since A. Aether does not exist. B. Fields have nothing to do
with particles. This only leave C. Magic.

To think that there is this
mysterious object, the "field", hovering all over that land that is
creating forces on people is just pure fantasy. It explains nothing.
(but can describe it quite nicely!)
Yes, "fields as a mathematical convenience". Rather than lengthy analogies to illustrate this already known and mentioned concept, why not say something about the actual issue? Is there any EVIDENCE that EM fields don't exist? If not, why the certainty that they don't in the face of things such as conservation laws? Things can be said about retardation, too.
Once can construct a working theory without conservation of energy etc in our usual sense, with no fields. It's been done, and does have some advantages. Notably, you can ignore the infinite self-energy due to the field of a point charge, since there are no fields. One breaks our usual conservation of energy, but in a way not needing magic (but needing assumptions about the future that might break our usual causality).

Post by Timo
Despite your protestations of innocence, you present a mathematical
description of the EM field where the field is written as the sum of
three terms. You proclaim that there isn't a single EM field, but 3
distinct EM fields. That appears very much like accepting the maths
as real.
Don't agree. Three FORCES are real!
You can't measure them independently. You can only measure the total force (to the extent that you can measure force).
Post by benj
The fact that they have different
characteristics means they are different and not the same.
They have different mathematical descriptions. So what? If I write the field due to a charge distribution as a sum of multipoles, every multipole order has different characteristics. Does that mean that monopole fields, dipole fields, and quadrupole fields are different fields in a meangingful physical sense?
Post by benj
Post by Timo
Are you now recanting? Have you switched to "EM fields don't exist"
as your new certainty?
Being imaginary is not the same as being zero.
Yes. Why avoid the question?

Point is: Sometimes mathematics seems to model the actions of
nature quite nicely and when it does it's rather useful in making
predictions to be tested and expanding understanding of the
phenomena.
But there is NO requirement that math reflect nature.
There is a requirement that our mathematical descriptions of nature
reflect nature. Otherwise they're not very good descriptions. Whether
first-principles theory or phenomenological models, mathematical
models/descriptions of nature reflect nature.
This is the crux of your error RIGHT HERE! This is your
misunderstanding of what maths are and where they come from. And that
makes YOU an example of exactly the problem I've been talking about!
It isn't about where maths comes from; it's about where our mathematical models of nature come from. Our mathematical models of nature reflect nature because we have constructed them to reflect nature. Why is that so hard for you to understand?
Probably because the statement isn't true. I'm still looking for those
dimensionless or infinite objects.

So admitting that not all maths reflect reality now
throws the WHOLE mathematic structure into doubt which was built up on
the assumption that maths did reflect reality!
It wasn't built on the assumption that maths reflects reality. (Well, maybe originally, but certainly not with the axiomatisation of mathematics.) So what would be thrown into doubt?
Post by benj
If you say well, the mathematical models that reflect nature, certainly
all reflect nature, that may be a true statement, but it's not very
enlightening!
I see it as obvious rather than enlightening. I only mentioned it since you were arguing against it.
I'm convinced! Mathematics is obviously the true structure of all
reality, and therefore IF we have the brainpower to calculate the maths,
THEN we can immediately discover the true nature of how all of nature
works. How could I have ever argued against that?

I'm off to calculate "point charges" using infinite fields!

Discussion over.

Second, we use many mathematical models that are approximate. That are known to be approximate. We use them because they're simple, but still useful. If we model the Earth as an infinite conducting plane, the model can still reflect nature within its domain of applicability, even if the Earth is not an infinite conducting plane.

Transfer of energy and transfer of information are basically the same.

energy isn't transferred by waves or by kinetic energy in some form
(doesn't have to be "particles" as such, does it? But obviously need
"mass" and hence is "real") then by what? If you accept that photons are
not waves (I don't) and not particles (clearly exhibit some particle
behavior in the transfer times of energy), then one is by elimination
left with "c". For which you have no mechanism so I called it "magic"!
You basically are saying "well, maths says the energy is transferred,
therefore that "explains" it!" But maths is fantasy, It "transfers"
nothing. It only models the transfers. Figuring out WHAT is doing the
energy transfers is not the job of maths but of Philosophy!

“The question of the “truth” of the individual geometrical propositions
is thus reduced to one of the “truth” of the axioms. Now it has long
been known that the last question is not only unanswerable by the
methods of geometry, but that it is in itself entirely without meaning..."

knows because the "field" is just mathematical fantasy. The fantasy is
constructed so as to reflect the forces observed which are obviously
real even though we have no idea where they come from, but again I used
my example of the wind and the field describing the forces produced by
the wind. The field is not real. It is a mathematical description. The
axioms behind that description can't be proved real. The question is
stupid. The wind is real and the forces are real but the "field" is
clearly NOT the wind! And to pretend that it is would simply be making
mathematics more real than reality.

Of course not. How is this progress? I never said otherwise.

"Fields" are not "maths". We describe them mathematically; we have
mathematical models of their behaviour. Those models don't make
fields cease to exist.
But it doesn't make them exist either! Point (again) is that
mathematical description known as "fields" is fantasy and does not exist
in reality. Whether or not there is an analog to that description in
reality that approximates the characteristics of the the fields is
unknown and unproven. So to talk about mathematical fields as if they
were real objects is simply wrong. To talk about the thing in reality
that may be an analog to mathematical fields is correct, but there is
very little actual knowledge to prove such a proposal. The main

therefore reality must be just like maths. See how we are edging toward

there are "invisible fields" out there producing the forces. Well, the

Where is the "clear statement"? That page says "The fact that non-locality does not imply the possibility of superluminal signalling might appear particularly surprising; this fact will seem less surprising, however, if one keeps in mind that the concept of superluminal signalling involves anthropocentric notions such as controllability and observability that play no role in the concept of locality." which is a clear statement of the opposite.

No. Why would it? There's a reason why experimental evidence is important in science.

What kinds of experimental evidence do we have that EM fields exist?

(a) Energy appears to be conserved, for things not involving EM fields (and some other kinds of fields). If EM fields don't exist, we have difficulties with conservation of energy. We could (i) assume that EM fields exist, and they transport energy, (ii) assume that something else transports the energy, and has transports the energy in the same way, quantitatively, as predicted by our models assuming the EM fields transport energy, but is NOT an EM field, or (iii) give up conventional conservation of energy. When a lizard sunbathes to warm itself, is it being warmed up by the light, or by some other "thing" transporting energy from the sun to the lizard? If I concentrate the light, I concentrate the energy. I'd say that burning glasses, lasers, solar cells, vision, radio, x-rays, and more - physical phenomena involving energy going from point A to point B are good evidence of the physical existence of EM fields. Indirect evidence, since we measure energy transfer and forces, but still evidence.

(b) From QED, we have the suggestion that photons have as much reality as electrons. Why should the existence of EM fields be in any more doubt than the existence of matter?

We call our "Delta x" in a mathematical formula the "displacement of <...>", when it isn't. So what? Don't be confused by our usual shorthand!

And yet, 2 oranges and another 2 oranges gives a total of 4 oranges. The mathematical 2+2=4 corresponds to reality.

These days, with the axiomatisation of much of mathematics, one can say exactly what "2" means. But it's largely irrelevant. What matters is that 2+2=4 works to describe stuff in the real world. It doesn't work for everything in the real world; the solution to that difficulty is to use it where it works, and to not use it where it doesn't work.

Anyway, as I said earlier, the mathematisation of physics predates modern physics. The success of Galileian/Newtonian science, and Newtonianism in general, says something about the success of such mathematisation. There were objections, even at that time. Simplicio on maths and reality from "Two New Sciences": "The arguments and demonstrations which you have advanced are mathematical, abstract, and far removed from concrete matter; and I do not believe that when applied to the physical and natural world these laws will hold."

you only have two choices. 1. FTL transmission. 2. Hidden variables.
That's not at all what Bell's theorem says, according to what I've read.
You are correct, that is not what the theorem states. Nothing like it. It
says hidden variabls are not able to model everything quantum physics
predicts.

However, see this (second paragraph)

https://en.wikipedia.org/wiki/Bell%27s_theorem#Metaphysical_objections

If the hidden variables can communicate with each other faster than light,
Bell's inequality can easily be violated. Once one particle is measured, it
can communicate the necessary correlations to the other particle. Since in
relativity the notion of simultaneity is not absolute, this is
unattractive. One idea is to replace instantaneous communication with a
process that travels backwards in time along the past light cone. This is
the idea behind a transactional interpretation of quantum mechanics, which
interprets the statistical emergence of a quantum history as a gradual
coming to agreement between histories that go both forward and backward in
time.[23]

This may be what benj is thinking about.

But that's how everyone interprets it, at first
blush. It takes effort to understand that
entanglement doesn't imply FTL signaling.

Even some bright bulbs have been fooled.
Check Nick Herbert's FLASH device, which putatively
accomplished superluminal communication. It took a
lot of head scratching, before the flaw was discovered.

http://www.scientificamerican.com/article/mistakes-faster-than-light-telegraph-that-wasnt/

In Herbert's defense, he performed a service -
by stimulating research, progress ensued.
We learn from errors, right?

It supports it though. From:
<http://arxiv-web3.library.cornell.edu/pdf/1206.6578v1.pdf>

If it can be done per event, there is no good reason that an ensemble of
photons can not be used to transmit information. The only reason folks
argue with this is that it doesn't 'feel' right in relativistic terms.
There is nothing in SR that says information must be part of the SR
domain. It is only a human desire.

I haven't read the original source of the quote (the 1944
article), so I don't know what students Armstrong refers to. If
he's writing about beginning students, he's talking mechanics,
not EM theory. He is just talking about classical theory.
The students Armstrong is talking about were likely Electrical
Engineering students of the 1930s and 1940s. (Math and engineering
were rather different then...note his reference to plots and
charts)
... and trigonometric functions.
Have you read the original article, or are you guessing?
Not exactly guessing but I have not read the original. Story is I
encountered the article reference in working on another (unrelated)
piece by a different author. He suggested that Armstrong committed
suicide because of the extreme resistance to his views on science and
mathematics (a conclusion I think is rather over reached). But didn't
give the reference to the article. I found that the Armstrong biography
had his bibliography in it so I bought it for the reference. The Bio
included the quote from the article and a brief description of the
events surounding it. That's what I know. The quote speaks for itself.

Post by benj
However his beef, is relevant, which was the worship of mathematics
as more real than reality.
No. Nothing about "real" in the quote. Just about how to go about
getting results. He's complaining about over-dependence on
mathematics in coming up with ideas and results. Nothing to do with
your philosophy of the (un)reality of mathematics.
Note you are trying to pretend that this needs to be some kind of
irrefutable prove of my premise and that since it's not, I lose.
Sorry, this was only one nail in the coffin of math more real than
reality, not a proof of itself. You need to move on to my next post
with the quote from Einstein in which he characterizes geometry as fantasy.
The difference here between you and Armstrong is that you feel that
somehow math reflects the underlying wheelwork of nature. Therefore if
one does enough math and comes up with a prediction based upon that math
all that is then needed is to go measure the prediction, verify that the
math indeed was correct in the prediction et voila! It's another huge
success for math as the underlying basis for all reality.
Armstrong takes the opposite view, namely that while not denying the
above can work it is ALSO true that math can predict things that prove
totally false when measured. Hence the mathematics is NOT a
representation of the underlying wheelwork of nature but just a tool to
quantify results ONCE the person has a philosophy that seems to reflect
how nature works down in the wheelwork. In other words nature is real,
but mathematics is not.
As Einstein notes the reason math cannot represent reality is because it
is not based on reality at all. The idea is stupid. Math is based only
on self-consistency. The "truth" of the beginning postulates is not even
a question that makes sense.

---a lot !!
a lot that too many people still dont know or understand
--
it is the mass smallest units of mass and energy !!!

please note
each wave length has the same mass
no matter if a big wave length
or a small one !!
and now you can start to understand my historic forlulation
of the smallest photon energy unit

ie
E photon minimum - hf times n
while
n is the scalar part of Planck time !!
and if you divide it by c%2
you get the smallest photon mass unit
to be
about exp-90 kilograms
if you like a visual metaphor
to help you remember it
think about
a machine gun
shooting bullets that all of them are of the same mass
yet
there is such machine gun that shoots quick
and another one --that shoots slower etc etc
(yet all the bullets '' are the same mass and energy )

BTW
that is an old copyright metaphor of mine
from a few years ago !!!

yet it is a bit more than just a metaphor !
it is a metaphor close to reality

it is a metaphor close to reality
and explains a lot about that 100yeas long 'enigmas !
It explains that you are wrong. Let me show you .. if you're not a
coward you will answer

Lets says you have a torch which, in one second, emits 1,000,000,000
photons.

Can you then see that the torch emits 2,000,000,000 in two seconds?

Can you then see that the torch emits the same number of photons each
second?

Can you then see that the torch emits twice as much total energy
in two seconds than in one second?

Can you then see that the total
energy is proportional to the number of photons?

Can you then see that
each photon has the SAME energy, that is why when you double the number
of photons, you double the photon energy?

Can you then see that the
energy of each photon is the same?

Can you then see that the energy of
each photon is NOT time dependent?

If you don't see any of those facts,
why not?

Go on .. be a man and not a coward.

I don't know what the quote has to do with classical mechanics. Unless
you are saying that Galileo and Newton started the worship of
mathematics as reality that was finished by the worshipers of Einstein.
They (and many of their predecessors and contemporaries) started the primacy
of mathematical models in physics. Galileo also pushed the idealised thought
experiment quite strongly.

I haven't read the original source of the quote (the 1944 article), so I

talking about classical theory.

As expected, since the origins coincide (as they must,

Back before everyone began to worship Einstein's sphincter science and
invention, especially IMPORTANT inventions and science that greatly
changed the way every one lives and looks at the world, used to hold up
the practical persistence of Edison and the brilliant inspiration of
Tesla as examples.
From what I've read, pre-Einstein science did not have to do as much
with practical invention as you think. Classical mechanics was advanced
by the works of Lagrange and Hamilton. Electric and magnetic fields were
studied extensively by Heaviside, Faraday, and Maxwell, without much
thought for invention. And the big lion in the room was thermodynamics,
with blazing contributions by Boltzmann, Gibbs, Carnot, Lord Kelvin, and
a host of others.

Now you say below that the work of Tesla and Edison were understandable,
which may be, because that's technology, not science. But I'd be
interested to see whether the work of the above physicists (all
pre-Einstein) were of the same "comprehensible" sort that you think
Einstein and others trashed. So perhaps you can tell me something about
the significance of the Hamiltonian and perhaps solve a simple problem
with it. You can also talk to me about the definition of Gibbs free
energy and how exact differentials in thermodynamics are important for
it. I think you'll find that this complaint that you have about
post-Einsteinian physics in fact applies to pre-Einsteinian physics too:
You don't really understand ANY of it. So in that case, you're misfiring
at Einstein.

We've already established that you have trouble with the first four
chapters of an introductory physics text, which is all BASIC physics
from the pre-Einstein era. And so you call introductory physics material
"more advanced" because it is beyond you, and therefore it must be a
snow job.

Has it not occurred to you, Ben, that the problem is that you just don't
have a good understanding of any of it?
Post by benj
But then came Einstein and everything changed. Suddenly the measure of
science was not how practical you could make it in everyone's life but
rather how incomprehensible you could make it. The bigger the snow job,
the "higher" and "more advanced" the science was thought to be. The
measure of a scientist was no longer their discoveries of how Nature
worked as in the 19th century days of "Natural Philosophers" but rather
how obscure your mathematical derivations were. Science turned on it's
head.
And oddly Einstein himself took the opposite viewpoint asserting that
advanced physics could be explained to a barmaid if you understood it.
Well, that was a pithy comment by Einstein, yes. He was known for his
pithy comments. But as you see, we got bogged down on chapter 1 of his
book written for barmaids. So what does that tell you about pithy
comments, or about the comprehension level of you and barmaids?

Thank you Einstein! And you see it here in a host of paul drapers and
others worshiping Albert's sphincter and assuring everyone that science
is really all about a semantic debate over words and that mathematics is
more real than reality.

It's worth mentioning that the Professor Armstrong cited here is Edwin
Howard Armstrong, who was written about in a book called "Man of High
Fidelity" by Lawrence Lessing, and in which the above quote is
mentioned. E.H. Armstrong was an electrical engineer and inventor,
principally in the area of radio. He was also (and again this fits in
with Ben's adoration of contentious geniuses like Tesla) heavily engaged
in frequent and prolonged legal battles, and this eventually took a toll
on his mental health. He battered his wife with a fireplace poker, and
when she left him, he threw himself out of a window to his death.

The quote above was actually not so much about physics and CERTAINLY not
about relativity, as it was about the engineering technology behind FM
transmission, principally the battle between narrow-band and wide-band
FM. His target in the article was in fact applied mathematicians, as
Lessing's book makes abundantly clear.

Back before everyone began to worship Einstein's sphincter science and
I used to worship mathematics, and then I worshiped physics and engineering, and now I don't worship any of them. As I see it, there are:

1. Physics intuition (very good!).
2. Mathematics intuition (very good!).
3. Reality-orientation (very good!).
4. Abstract-orientation (very good!).
5. Experimental-orientation (very good!).
6. Proof (logical-mathematical)-orientation (very good!).
7. Invention-Discovery-orientation (very very very good!).
8. Ethics, Honesty, Consistency (very very very good!).
9. Orientation toward the Scientific Method (very very very good!).

I don't think that one can get very far without ALL of the above, at least not in the long run or beyond one or two discoveries. I should also add, including regarding my comment on not getting very far:

10. STOP ATTACKING OTHER WRITERS ON SCI.PHYSICS (this is directed not to Benj but to all TROLLS, even those who abandon Trollness in some threads) without have balanced critiques (mention some good things and don't leave out any of the above in your critique - more or less). Even totally mixed-up writers deserve better than to be attacked endlessly by negativistic trolls (usually with short one-line or two-line criticisms).

I'd also recommend that all readers/writers on sci.physics learn PSYCHOLOGY and POLITICS. Admittedly, much if not 99%+ of politics is for the birds so to speak, but there's a tiny bit that is very relevant to the real world including JOBS for scientists and ETHICS for scientists.

As for psychology, some of it is for the birds (especially exclusive focus on the "Oedipus complex" and one's mother), but it's really need for TROLLS, for people who want to counter TROLLS, for people with gripes about over-emphases in physics or by physicists, etc. It also would greatly help COURTESY on sci.physics. The super-discourteous TROLLS on sci.physics (and now we allegedly have part-time TROLLS who seem to recover their brains in some threads) are tending to worship EMOTIONALITY instead of focusing on science, regardless of what they claim to say. Some of them may also be politically motivated - the psychology of politics is quite interesting and relates to DOGMATISM, Achievement Motivation, Self-Regulation, etc.

Actually the trolls here to disrupt Sci.physics know EXACTLY what they
are doing. They are extreme and discourteous for a reason. They
understand the psychology of what they are trying to do (and so do I)
and play it to the max.

Politics is about power and fooling the gullible for your own gain.
Psychology is what you use to fool the gullible. And that means fantasy
and lies. You make up plausible lies. You create an emotional
atmosphere. You attempt to trigger all those childhood behaviors that
have reflexive responses (name-calling, and all other recess behaviors)
and you do it to create your purpose. Typically the purpose is either to
promote some falsehoods in the name of science (which the public
generally still respects) like say "global warming" or the purpose is to
discourage a discussion from drifting into topics where information may
come to light that should remain hidden for political reasons (most of
the "forbidden" topics in science).

This is what "strategic writers" are for. They run terminals with as
many 20 or so "personalities", all fake and all designed to troll the
relevant internet groups for disruption and manipulation. They use their
emotional tricks to make sure that reasonable, polite, intelligent
discussions of important topics NEVER can take place.

Of course it would be best if such discussions never had a place to
occur in the first place, so disruption would not be necessary, thus,
the effort to eliminate USENET from the INTERNET. Google was by far the
simplest and easiest to use for most people, so trashed their system
making it useless. ISPs pulled USENET servers off their service.
Internet Backbone service was changed to make USENET servers pay large
fees to continue to operate. In short, those in power DO NOT want you
discussing what they are up to or figuring out what part of the
"official" news is lies.

So when Obama says "global warming is real and careening out of control"
there will be nobody allowed to say he's lying.

And that's how it is.

HEY! Home come you left me out! Who here believes in #8? Nobody!

Ethics, Honesty, consistency, morality are all for the atheist scientist
nothing but religious fairy tales!

Everyone knows that humanity developed from animals through evolootion.

Animals have no ethics or morality. They only have survival instinct. So
it is with man. Might makes right! If animals want something they take
it. IF someone gets in their way they kill them. There is no hand (paw)
wringing over "sin"! Animals survive by "spoofing" each other. They
survive by evolving the coloration of other predators or they survive by
coloration or behavior that imitates other animals or objects of no
interest to potential predators. Lies and disinformation assure survival
of the species. Can man do any better?

Most scientist have atheism as their religion and know evolootion to be
the true nature of man. And that more than enough justifies all the
political lies, the back-stabbing, the use of power to further your own
reputation over that of others no matter how smart they are or what
they've achieved. It's all about who "wins"!

Climate science, Secret weapons, political science lies, stalling of the
advancement of civilization to further your own ends are ALL justified
beyond any question by science and evolootion. It's just how life on
Earth is. Science says so.

You turn my argument on it's head! Of course math is a tool. The problem
I'm discussing is that people have decided that math represents reality
and that IF you can just develop enough math, you can therefore learn
how reality works. This idea is totally false because math (fantasy) can
NEVER "prove" reality.

======

“The question of the “truth” of the individual geometrical propositions
is thus reduced to one of the “truth” of the axioms. Now it has long
been known that the last question is not only unanswerable by the
methods of geometry, but that it is in itself entirely without meaning..."

"The concept of “true” does not tally with the assertions of pure
geometry, because by the word “true” we are eventually in the habit of
designating always the correspondence with a “real” object; geometry,
however, is not concerned with the relation of the ideas involved in it
to objects of experience, but only with the logical connection of these
ideas among themselves”

Albert Einstein “Relativity” 1919


Got that? "entirely without meaning"! Seems clear enough.

Back before everyone began to worship Einstein's sphincter science and
There are two especially dangerous "instruments" of "anti-science" of the Einstein-Heisenberg type:

1. Bad Teaching (almost universally prevalent).
2. Worship of scientists.

I am also tempted to add, which I will:

3. Living in an anti-science nation dedicated to EMOTIONALITY.

Einstein was a DUNCE in teaching, he contributed heavily to worship of scientists (even his house cleaner, with whom he lived, worshipped him), and he was utterly uninterested in changing the Emotionality of whatever nation he lived in, from Switzerland and Germany to the USA except insofar as Germany hated Jews.

It was no coincidence that Einstein believed in worship of scientists. He and Heisenberg were Germans, and Germany was almost synonymous over millennia with worship of leaders. Even Luther, who rebelled against the Catholic Church, came to be worshipped. That's how Hitler came to power - not because he had mysterious hypnotic ability on his own, but because both he and his audiences were hypnotized by Leader-Worship.

Optimal would be some thermally isolated reservoir
along the path from the collector to warm water tap.

Note that there is huge difference
between properties of surfaces
for visible light and thermal IR radiation.

E.g. for the latter, snow is near "IR black"
in sense it absorbs near all thermal IR radiation,
and is for this also near ideal black body radiation source.
That is reason,
why during winter season areas with a snow cover
have usually lower morning temperature.
( at comparable weather conditions )

Generally, most of materials are very good thermal IR absorbers.
Exceptions are e.g. metallic thermal foils that reflect most of it.

So it should have black colour,
as majority of energy of Sun radiation
is in the visible range.

For radiation of the heat during the night,
it almost does not matter, as black and white colours
are comparably "black" for thermal radiation.

It cannot be the foil, as it would reflect the light.

General truth is,
the better some surface absorbs some EM radiation,
the better it thermally emits it.

But the point is,
while the collector radiates thermal IR during the night,
it does not absorb significant thermal IR during the day,
but in majority the visible light.

The difference in absorption/emission properties
for IR radiation is much smaller that for visible light,
For thermal IR, most of surfaces
are like "IR black" ( e.g. snow ) or at least "IR dark".

So I would go for black.

But Optimal would be
a thermally isolated reservoir along the water path.

needs to be insulated by an optical filter, that lets in white light,
and reflects IR. (plain glass sheet, (greenish with iron is better),
two sheets is better. Solar water heating.

the white light goes through it, hits the black absorber paint which
converts white light to IR, and the IR is trapped inside the box so you
can remove it using water or air.


https://en.wikipedia.org/wiki/Emissivity
https://www.engineeringtoolbox.com/emissivity-coefficients-d_447.html

you can also cool at night, without the glass, radiate from a pool of
water to cold space, but that effect is smaller, and you have to keep
the sun off it, and it should only see the sky above not much
environment. the sky is very cold, measure it with an IR temp sensor.
Some guy did that to his house, had a 6" pool of water above his house,
wind protected, etc.

Don't use the tank itself to heat the water. Use flat, black water
circulation-type rooftop collectors, passive circulation, and a
well-insulated tank painted any color you find pleasing.

When the sun stops heating the collectors, circulation slows waaay down,
and the hot water in the tank won't radiate heat back out of the
collectors.

All mature technology. You can find plans on-line for assembling it.
You can buy the parts right off the shelf.

I have a book around here that has all of the design equations for these

surface materiials to use for absorbing heat.
Interesting design area.

You can build these yourself, I think Copper Black was very good

White on the outside, white on the inside, would be ideal, for the reason
that you mentioned.

There is a problem with that: There is no suitable white-colored metal (at
least I do not know of any, nor do I know a suitable alloy that would have a
white color). Suitable metals, like aluminium, and their alloys, tend to be
silvery, so colored varnish would be required to for a white color. But
varnish is not very heat-resistant; it is also highly flammable, affected by
contact with water, and can be toxic as it can give off formaldehyde
(methanal), which is toxic and carcinogenic.

Sunset time is irrelevant, of course, as sunset will not be at the same time
during the year, ignoring other factors.

To answer your non-question:

1. You are falsely assuming that a water tank would have to be of one color
on the inside and outside;

2. You are falsely assuming that water would have only one phase, liquid;

3. You are making uneducated guesses about the temperature of water at
certain times of the day, without knowing or considering the physical
properties of the water tank’s material, such as its thickness, its
heat capacity and conductivity, and that of water. Nor are you
considering environmental factors, such as the intensity of the incoming
radiation, the albedo of the surface, wind, and precipitation.
This approach is hopeless.
Post by micky

Those are not questions. Learn what a question mark is.

To answer your non-question: White, very heat-resistant varnish on the
outside, no varnish on the inside. Otherwise (no varnish or dark varnish
outside in an attempt to get hot water more easily) the tank will heat up
faster when exposed to sunlight, and the water in it will evaporate more
easily, leaving less *liquid* water for use. A tank that is painted dark on
the outside might also burst more easily due to temperature-induced stresses
(hot during the day, cold at night).

Incidentally, you will find that public water tanks, for example in the
United States of America and in Australia, tend to have white varnish on the
outside if they are out of metal. The all-white old water tower at Warner
Bros. Studios in Burbank, California, readily comes to mind there.

And the plastic containers for all kinds of liquids are usually out of white
plastic. I do not think that is a coincidence either.

maybe before sundown and very likely the water will be almost cold by 7.


Which of my statements, clauses, adjectives, are incorrect?

What color should the tank be for best hot water? The most hot water?


Ignore the possibility of sometimes using a supplemental electric
heater, except that the solar heater is to be designed to make that as
little necessary as possible..

Assume a large metal tank of water is placed on top of a house to
provide hot water for the kithen sink and the bathroom sink and tub.
Assume sundown is at 6. What color should the tank be?
AIUI, white will not absord the heat as well, but it will keep the heat
it does absorb longer, so there will be hot water until 7,8,9 PM
But black will absorb the heat faster, will be able to absorb more heat
on grey days, and will have hot water ready by noon instead of 2PM.

Why do you post the same question again,
when you have already got a lot of answers ?

The majority of absorbed energy is visible light, not heat,
as majority of incident power is in visible range.
The heat is created when the light is absorbed.

In thermal IR region, both black and white colours
are generally comparably "IR black or at least dark",
in sense of absorption and emission of thermal IR.

Therefore, heat loses difference is negligible.
( Blacking of electronic cooler radiators is
because they are metallic, not light,
and difference is not drastic )

So, the solution is black. FIG 1

Optional, but with high advantage,
is to create a passive water circuit, FIG2
with the collector separated from a reservoir,
powered by water density difference.

The collector is best to have a low volume,
from set of black tubes,
surrounded by focusing reflecting surface,
like alufoil in half circle shape.
This would increase the water temperature

Separation of the collector and reservoir
has another reason for higher efficiency:

Until the reservoir is full,
the collector is still filled by cool water,
so water heating rate is not disturbed.
