Be sure that not only me, but the whole physics community would accept the result of that experiment, after checking the conditions and statistical analysis of the results.
For sure, you are aware of how real experiments are performed and how to perform the experiment, are you not?

    Einstein was greatly influenced by the philosopher-physicist Ernst Mach who was an advocate of logical positivism. According to logical positivism, physics should only make statements about phenomena which could be directly observed and measured. Using logical positivism as his guide, Einstein simply stated: "Time is what we measure with a clock".  According to Einstein, there was no place in physics for philosophical musings about the nature of time — all that was important was what could be measured.
    This statement of Einstein is particularly important because the theory of special relativity states that a clock which is moving will appear to run at a slower rate than a clock which is stationary. And, as Einstein stated that "Time is what we measure with a clock", this would appear to indicate that time itself runs slower for an observer who is moving relative to a secondary observer.

In the more general sense, the more recent development of the so-called Copernican principle states that no particular point in the universe (not just the Earth) can hold a privileged position in the universe. This heralds a move away from an absolute system of science and cosmology to a science which realises that no observer holds a privileged position, and that the universe is built on relative measures. The repercussions of the Copernican principle are rippling through science to this day, perhaps having its greatest impact in the theory of relativity: if no observer holds a privileged position, then all motion must be described relatively. If you have read my previous two books you will know I have a firm conviction that the universe is built on fundamental principles — principles which are "obviously correct" and would have to be true in any conceivable universe. The Copernican principle is surely another of these fundamental principles: surely no point — and therefore no observer — holds a privileged position in any conceivable universe.

Galileo's greatest contribution to the world of science was his scientific method. Before the scientific method was introduced, the proclamations of ancient philosophers such as Aristotle were accepted without question as representing the absolute truth about Nature. Galileo was one of the first scientists to challenge the wisdom of the ancients. Galileo's introduction of the scientific method allowed Nature to speak for itself. Aristotle was no experimenter, and he relied too much on his preconceptions. Famously, Aristotle once proclaimed that women have fewer teeth than men. Because no one thought to check this proclamation of Aristotle, for a thousand years everyone believed that women have fewer teeth (women and men, of course, actually have the same number of teeth).

The only conclusion which is left to us is that reality itself is different for both Alice and Bob! In Alice's version of reality, the lightning bolts hit the ground simultaneously. In Bob's version of reality, the lightning bolts did not hit the ground simultaneously. Reality is a relative concept for the two observers. This extraordinary outcome of the experiment is called relativity of simultaneity.

If I am moving relative to you, then my reality is different to your reality.

If you remember, Galilean relativity states that the laws of motion are the same for all observers who are moving at a constant velocity. There is no experiment you could perform to determine if you were stationary or moving at constant velocity.

In the discussion of the block universe in the previous chapter, it was described how all times are equally real and there is, therefore, no special "now" pointer which moves through time at a certain speed and determines the current moment. Even though we derived this result in a logical manner, there still lingers a considerable amount of resistance to this model. For example, Lee Smolin recently devoted an entire book, entitled Time Reborn, in an attempt to refute the block universe. The main reason I feel that many people have such a problem accepting the block universe model is not through any rational scientific basis, but because they instinctively feel a special "now" moment. This feeling is so utterly entrenched into our lives and psyche that it is an incredibly hard habit to break.

For most of history, passports were neither so ubiquitous nor so routinely used. They were, essentially, a threat: a letter from a powerful person requesting anyone a traveler met to let the traveler pass unmolested—or else. The concept of passport as protection goes back to biblical times. And protection was a privilege, not a right: English gentlemen such as Gadsby who wanted a passport before venturing across the sea to France would need to unearth some personal social link to the relevant government minister.

You could visit 1890s America without a passport, though it helped if you were white.  In some South American countries, passport-free travel was a constitutional right.  In China and Japan, foreigners needed passports only to venture inland.

It’s hard to remember just how bad search technology was before Google. In 1998, for instance, if you typed “cars” into Lycos—then a leading search engine—you’d get a results page filled with porn websites.  Why? Owners of porn websites inserted many mentions of popular search terms like “cars,” perhaps in tiny text or in white on a white background. The Lycos algorithm saw many mentions of “cars” and concluded that the page would be interesting to someone searching for cars. It’s a system that now seems almost laughably simplistic and easy to game. But at the time, nothing better was available.

The data are clear that the washing machine didn’t save a lot of time, because before the washing machine we didn’t wash clothes very often. When it took all day to wash and dry a few shirts, people would use replaceable collars and cuffs or dark outer layers to hide the grime on their clothes.

On 10/3/19 4:03 PM, Ed Lake wrote:

"Take a situation where I am on a moving train and I shine a flashlight at the forward wall of the train.  The mathematicians on this forum BELIEVE that the light will hit the forward wall at c, not at c-v, where v is the speed of the train."

When you say "the light will hit the wall at c-v", what you really mean is: as the light approaches the wall, the light is moving with speed c-v relative to the inertial frame in which the wall is at rest.

Your claim is, of course, directly in conflict with Einstein's second
postulate:

        2. Any ray of light moves in the “stationary” system of co-
        ordinates with the determined velocity c, whether the ray
        be emitted by a stationary or by a moving body.

        (Earlier the "stationary system of coordinates" was
         defined to be an ARBITRARY inertial frame, so this
         applies to EVERY inertial frame, including the one
         in which the wall is at rest.)

Your claim is also directly in conflict with his SUMMARY of that
postulate in his introduction:

        light is always propagated in empty space with a definite
        velocity c

When you say "the light will hit the wall at c-v", what you really mean is: as the light approaches the wall, the light is moving with speed c-v relative to the inertial frame in which the wall is at rest.

You wrote the following today, referring to my comment that SR does considers that both the pòint of view of the train observer and the point of view of the embankment observer are equally valid :

"If two observations conflict, how can they be "equally valid"?  That is illogical.  But, of course, mathematicians do not believe in logic.  Scientists believe in logic, and when they encounter conflicting observations, they make it their job to find out what the problem is.  In this case, the problem is the dogmatic beliefs of mathematicians".

The problem here is not one of logic but one of observing very real events (the lightning strokes). The observations clearly depend on where the different observers are located when the events occur. In the train embankment gedanken, one observer is stationary at point M on the embankment, while the train observer is stationary at point M' and moving with the train at speed v with respect to the embankment.

The reality of the events can not be disputed. What Einstein is discussing is how those events are observed and the analysis of Einstein leads to the conclusion that: Events which are simultaneous with reference to the embankment are not simultaneous with respect to the train, and vice versa (relativity of simultaneity).

Therefore, one observer may declare he saw lightning A before B, another may declare he saw lightning B before A and another may well declare both lightnings were simultaneous. 

Are all these observers nuts? For sure they are not since each of them is reporting what he actually saw. Notice that the actual events A and B may well not have been simultaneous, to begin with, but the observations of the events will be different for different observers.

Then you wrote the following:

"Science says that the boy on the plane is seeing an illusion when he sees the ball go straight up and down.  The ball cannot possibly be going straight up and down if it is on a plane traveling at 500 mph. Science also says that the man on the train is seeing an illusion when he sees the lightning bolts hit at different times.  The man on the embankment is seeing reality when he sees the lightning bolts hitting simultaneously".

First, Science says nothing of the sort. In physics there are no "illusions" but observations. The boy on the plane is actually seing what he sees (the ball going up and down).

Secondly, You are giving the ground observer (the guy seeing the plane passing by his location) the unwarranted privilege of be the only one allowed to see reality. What God gave the ground observer such privilege?

Again, Einstein explanation is clear and not subjected to any interpretation. Then Einstein concludes writing:

"We thus arrive at the important result:Events which are simultaneous with reference to the embankment are not simultaneous with respect to the train, and vice versa (relativity of simultaneity). Every reference-body (co-ordinate system) has its own particular time; unless we are told the reference-body to which the statement of time refers, there is no meaning in a statement of the time of an event".

This should stop any discussion about c+v or c-v or which point of view is real or not.

#4.  The speed of light is always measured to be the same by the emitter and by all outside observers, regardless of their own velocity.

First, SR does considers that both the pòint of view of the train observer and the point of view of the embankment observer are equally valid, period.

both the pòint of view of the train observer and the point of view of the embankment observer are equally valid, period.

The same analysis is true with respect to me seating in my living room watching a TV show. It is of no interest to me or to anybody on Earth, that Earth is really going at 30 km/sec around the Sun or rotating at 1000 km/hr around the poles. My physics related to eating a sandwich is exactly the same physics of eating a sandwich inside an airplane. 

This clearly shows that Lake can't understand what he reads!!!
Notice his writing:

"When the man on the train turns on the overhead light, he doesn't notice that the rear wall lights up first because, while the light reached that wall faster than the front wall, the man is moving away from that wall..."

That is, Lake insists that, somehow, the standing observer inside the train MOVES with respect to the couch walls!!!

Therefore, it is no surprise he concludes with the following book worth sentences:

"The key point is: What the man on the train sees is an illusion resulting from the fact that he is on a train and is moving with the train.  It is similar to a boy on an airplane tossing a ball up and down.  The boy sees the ball going straight up and down, while an observer on the ground would (theoretically) see the ball traveling in an arc covering thousands of feet as the plane moves through the air.  The man on the ground sees what is actually happening, the boy on the plane sees an illusion."

You see, according to Lake, the food we ingest inside an airplane is an ILLUSION

This is too much fun.

But it won't cost you anything!  You say the company has assured you that the device will read 60 mph when pointed at the inside of an opaque truck driving down the road at 60 mph.  All you have to do is tell them you will purchase the gun based on their assurance that it works that way.  Tell them, straight out, that if you receive the device and it doesn't work as advertised (i.e., the way you say they say it works), you will be returning it for a full refund.

You can't lose.  If the gun works as you expect, you will be making millions of dollars (including the million dollar Nobel prize) as the man who over-threw all of science.  So the $1600 investment will be repaid a thousand-fold.  On the other hand, if the gun doesn't work as you expect, you get a full refund.

Either way, you can't lose.  So what's stopping you?

Our new assumptions are:
(1) The velocity of light in vacuo is the same in all C.S. moving uniformly, relative to each other.
(2) All laws of nature are the same in all C.S. moving uniformly, relative to each other.

The relativity theory begins with these two assumptions.  From now on we shall not use the classical transformation because we know that it contradicts our assumptions.

It is essential here, as always in science, to rid ourselves of deep-rooted, often uncritically repeated, prejudices.  Since we have seen that changes in (1) and (2) lead to contradiction with experiment, we must have the courage to state their validity clearly and to attack the one possibly weak point, the way in which positions and velocities are transformed from one C.S. to another.  It is our intention to draw conclusions from (1) and (2), see where and how these assumptions contradict the classical transformation, and find the physical meaning of the results obtained.

Once more, the example of the moving room with outside and inside observers will be used. Again a light signal is emitted from the centre of the room and again we ask the two men what they expect to observe, assuming only our two principles and forgetting what was previously said concerning the medium through which the light travels. We quote their answers:

The inside observer: The light signal travelling from the centre of the room will reach the walls simultaneously, since all the walls are equally distant from the light source and the velocity of light is the same in all directions.

The outside observer: In my system, the velocity of light is exactly the same as in that of the observer moving with the room. It does not matter to me whether or not the light source moves in my C.S. since its motion does not influence the velocity of light. What I see is a light signal travelling with a standard speed, the same in all directions. One of the walls is trying to escape from and the opposite wall to approach the light signal. Therefore, the escaping wall will be met by the signal a little later than the approaching one. Although the difference will be very slight if the velocity of the room is small compared with that of light, the light signal will nevertheless not meet these two opposite walls, which are perpendicular to the direction of the motion, quite simultaneously.

Comparing the predictions of our two observers, we find a most astonishing result which flatly contradicts the apparently well-founded concepts of classical physics. Two events, i.e., the two light beams reaching the two walls, are simultaneous for the observer on the inside, but not for the observer on the outside. In classical physics, we had one clock, one time flow, for all observers in all C.S. Time, and therefore such words as “ simultaneously”, “ sooner”, “ later”, had an absolute meaning independent of any C.S. Two events happening at the same time in one C.S. happened necessarily simultaneously in all other C.S.

Assumptions (1) and (2), i.e. the relativity theory, force us to give up this view. We have described two events happening at the same time in one C.S., but at different times in another C.S. Our task is to understand this consequence, to understand the meaning of the sentence: “Two events which are simultaneous in one C.S., may not be simultaneous in another C.S."

On March 16, 2018, just twenty-six hours before his scheduled retirement from the organization he had served with distinction for more than two decades, Andrew G. McCabe was fired from his position as deputy director of the FBI. President Donald Trump celebrated on Twitter: "Andrew McCabe FIRED, a great day for the hard working men and women of the FBI - A great day for Democracy."

Donald Trump would not know the men and women of the FBI if he ran over them with the presidential limo, and he has shown the citizens of this country that he does not know what democracy means. He demonstrates no understanding or appreciation of our form of government. He takes no action to protect it. Has any president done more to undermine democracy than this one? His “I hereby demand” tweet in May 2018, ordering Department of Justice investigations of the investigators who are investigating him—I can barely believe that I just wrote that phrase—is a clear example. His demand for documents identifying confidential informants does harm to the men and women of the FBI on a fundamental level. It undermines their ability to build the trust that allows law-enforcement investigations to take place, in ways that, I want to believe, he does not comprehend.

I am not aware of another president who has weighed in against ongoing criminal prosecutions in the overt, hostile, and unrelenting way that President Trump has. This is a breach of propriety and of historical norms. Presidents don’t weigh in on those things. They don’t try to tip the scales of justice for or against a particular defendant. In our system, intervention from the outside is not only considered inappropriate—it is inappropriate. It undermines the operation of a fair system of justice. It sows seeds of mistrust.

In section III the author discusses the problems he has because he doesn't understand special relativity. First he compares different statements used as the second postulate. Of course it makes little difference which postulates one uses as long as they result in the same theory, and there are presentations of the theory that don't use Einstein's second postulate at all. (In Einstein's original article the word "postulate" is not used but postulates were called "principles" instead.)

The reader should not let the author's archaic use of the word "mathematician" to confuse oneself. Although the meaning is more restricted in the modern language, there is a tradition to use it more generally to mean 'a person who can think rationally', and this old meaning is used in the article.

Physicists and mathematicians utilize mathematical principles to validate theories. Both fields apply their work to solve practical problems. A physicist specializes in examining how different types of components, such as energy and matter, interact. In contrast, a mathematician conducts research or experiments to further understanding of subjects like geometry or algebra.

 

• The Classic Model is a stationary mode radar and is not intended to be used in a moving vehicle.
• The Classic Model radar tracks the strongest signal. It displays the speed of the vehicle with the strongest radar return, which is typically the closest vehicle.
• The Classic Model measures vehicles that are approaching and receding from the stationary radar position. It does not discriminate the direction of the moving vehicle. 

In 2017, another experiment was done using strontium clocks, whose accuracy is three times that of cesium clocks, and the theory of
relativity was once again upheld (Ananthaswamy, 2017).

Special relativity established that the laws of physics are the same for any two observers moving at a constant speed relative to each other, a symmetry called Lorentz invariance. One consequence is that they would observe each other’s clocks running at different rates. Each observer would regard themselves as stationary and see the other observer’s clock as ticking slowly – an effect called time dilation.

Now, Pacôme Delva of the Paris Observatory and his colleagues have used strontium clocks to test time dilation. Two optical fibre links, one between London and Paris and another between Paris and Braunschweig, Germany, were used to compare devices in these locations.

These clocks are moving at different velocities because of their position on the Earth’s surface, and relativity makes precise predictions about the extent of time dilation they experience. For example, a clock closer to the equator should tick more slowly than one closer to the North Pole. After one day, clocks in Paris and London should show a difference of 5 nanoseconds.

“A violation of Lorentz invariance could point to a way to combine relativity and quantum mechanics”

Phase compensated optical fiber links enable high accuracy atomic clocks separated by thousands of kilometers to be compared with unprecedented statistical resolution. By searching for a daily variation of the frequency difference between four strontium optical lattice clocks in different locations throughout Europe connected by such links, we improve upon previous tests of time dilation predicted by special relativity.

The clocks were located in Teddington, England (near London), Paris, France, and Braunschweig (a.k.a. Brunswick), Germany.



Unfortunately, the article doesn't seem to have anything meaningful that I can quote.  It's an article that is filled with mathematics, and its prime purpose seems to be to prove a violation of the Lorentz invariance.  According to Wikipedia:

In relativistic physics, Lorentz symmetry, named after Hendrik Lorentz, is an equivalence of observation or observational symmetry due to special relativity implying that the laws of physics stay the same for all observers that are moving with respect to one another within an inertial frame. It has also been described as "the feature of nature that says experimental results are independent of the orientation or the boost velocity of the laboratory through space"

Einstein was both general relativity’s progenitor and quantum theory’s greatest critic. History may show whether neither, one or both of his sets of ideas were right. In the meantime, the nature of space and time seems as good a place to start as any to begin sorting out what’s what. Physics works by the minimisation of mysteries, and their current multiplication suggests that whatever we’ve got wrong, it is something pretty fundamental.

What are the many factors that many people might share that go against the acceptance of scientifically valid new ideas? One obvious factor that has always been with us is the unwillingness to learn new things. Too many people think that what they learned in college or in the few years thereafter is all that there is to be learned in the subject, and after that they are practitioners not having to learn anymore. Of course especially in a period of fairly rapid evolution that is very much the wrong attitude; but unfortunately it is shared by many.

a motivation that hones out new ideas, is what I brutally call the "herd" instinct. It is an instinct which humans have. It presumably dates back to tribal society. I am sure it has great value in sociological behavior in one way or another, but I think on the whole the "herd instinct" has been a disaster in science.

It is not just the herd instinct in the individuals that you have to worry about, but you have to worry about how it is augmented by the way in which science is handled. If support from peers, if moral and financial consequences are at stake, then on the whole staying with the herd is the successful policy for the individual who is depending on these, but it is not the successful policy for the pursuit of science.

Staying with the herd to many people also has an advantage that they would not run the risk of exposing their ignorance. If one departs from the herd, then one will be asked, one will be charged to explain why one has departed from the herd. One has to be able to offer the detailed justifications, and one's understanding of the subject will be criticized. If one stays with the herd, then mostly there is no such charge. "Yes, I believe that because doesn't everybody else believe that?" That is enough justification. 

It is now virtually impossible to do any research outside the widely accepted position. If a young man with no scientific standing were to attempt this, however brilliant he might be, he wouldn't have a hope. 

Once a herd has been established in a subject, it can only be broken by the most crass confrontation with opposing evidence. There is no gentle way that I have ever seen in the history of science where a herd once established has been broken up.

In many subjects such clear evidence is very hard to come by. In the complex subjects, especially I always think of the earth sciences in this respect, there are always different ways of interpreting any one fact; so many complicated things have taken place that any one fact can have three or four interpretations and the crass confrontation is very rare.

What does the refereeing procedure really look like? How does it really go on? If, for example, an application was made in the early 60's or late 50's suggesting that the person wanted to investigate the possibility that continents are moving around a little, it would have been ruled out absolutely instantly without questions. That was crack- pot stuff, and had long been thought dead. Wegener, of course, was an absolute crack-pot, and everybody knew that and you wouldn't have any chance.

Six years later you could not get a paper published that doubted continental drift. The herd had swung around - but it was still a firm and arrogant herd.

Shortly after the discovery of pulsars I wished to present an interpretation of what pulsars were, at this first pulsar conference - namely that they were rotating neutron stars. The chief organizer of this conference said to me, "Tommy, if I allow for that crazy an interpretation, there is no limit to what I would have to allow." I was not allowed 5 minutes of floor time, although I in fact spoke from the floor. A few months later, this same organizer started a paper with the sentence, "It is now generally considered that pulsars are rotating neutron stars."

There is only "REAL Time Dilation."  I've got a list of time dilation
experiments here: http://www.ed-lake.com/Time-Dilation-Experiments.html

Velocity Time Dilation experiments all begin by comparing clocks A & B to make sure they are synchronous and tick at the same rate. Then clock B is moved while Clock A remains in place.  When Clock B returns to be placed next to Clock A once again, Clock B shows that it experienced less time having passed while it was moving - just as Einstein said.

That confirms REAL time dilation.  But mathematicians DO NOT BELIEVE WHAT THE EXPERIMENT SHOWS.  Instead, they fantasize something that can never be demonstrated: They claim Clock B didn't actually run slower, it just took a longer path through "space-time."

Either way, the clocks showed that time dilation is REAL.  The experiments show that time dilation is NOT reciprocal.  It is NOT an illusion.  There are just people who do not believe what experiments show and confirm, instead they believe what they want to believe.  They require the IMPOSSIBLE to happen (like instantaneously comparing clock tick rates when the clocks are thousands of miles apart) before they will accept the facts.

is NOT a "velocity time dilation experiment" -- it is a total elapsed proper time experiment.

No, it does NOT. That confirms two different paths between a given pair of points can have different path lengths. That is _NOT_ "time dilation", it is a different geometrical phenomenon.

Two cars travel from Chicago to New York. One goes directly and the other goes via New Orleans. The fact that their odometers indicate different distances does NOT mean their odometers had different calibrations (i.e. ticked at different rates), it merely reflects the FACT that they traveled different paths and those paths had different path lengths.
        Ditto for the type of experiment you mention above.

Hint: if an experiment does not measure tick rates, one cannot conclude ANYTHING about the tick rates. That type of experiment measures and compares total elapsed proper times, not tick rates.

Introduction. Although evidence has been presented that the special theory of relativity for light has been confirmed and established [1- 4], other evidence suggests the contrary [5,6]. For example, Otis [6] found that the velocity of light in the propagation direction indeed is c, but when observers are in motion toward (or away) from the light, the increased (or decreased) light frequency f detected proves that the velocity with which light and observer approach each other differs from c because of motion of the observer. This motion cannot itself alter the wavelength w of the light produced by the source from which it speeds, where v (≠ c) = wf. This suggests to us that the postulates of the special theory of relativity need to be clarified. Indeed, light velocity can have component magnitudes other than c, which are usually referred to as aberration of light.

I read with pleasure your paper 'An Analysis of Einstein's Second Postulate".   It is great to find a bit of sanity out there.

I am an inventor who has been thinking about inertia, gravity and time for at least 60 years.  I never got very far beyond basic arithmetic in my education and am thoroughly put off by many papers that promise well but descend into heavy math even before they get the main idea across.  It is heartening that Einstein was also put off by his theories being hijacked by the mathematicians.  I didn't know that until I read your paper.

Krysha is the Russian word for roof. The word can be used literally or figuratively.  Krysha refers to the exterior top surface of something, such as a building or a car. Or krysha can refer to a person who provides the same kind of protection as a roof. “I’ll be your krysha”—I’ll be your roof—means that I will stop things from falling on you. Since the early 1990s, most businesses in Russia have had to operate with the protection of a krysha. Even if provided by the police or other government officials, the krysha is ultimately tied to organized crime. There is no effective distinction, in Russia, between organized crime and government, so kryshas have proliferated to where they block out the sky. Everyone lives under protection. The transformation has been systemic. It cannot be attributed exclusively to the actions of any one individual. But under the presidency of Vladimir Putin, the cohabitation of crime and government became the norm. Crime is the central and most stable force in Russian society.

Einstein was both general relativity’s progenitor and quantum theory’s greatest critic. History may show whether neither, one or both of his sets of ideas were right. In the meantime, the nature of space and time seems as good a place to start as any to begin sorting out what’s what. Physics works by the minimisation of mysteries, and their current multiplication suggests that whatever we’ve got wrong, it is something pretty fundamental.

   

Matter appeared within the first second after the big bang. Matter is the stuff that energy pushes around.

All forms of life require mechanisms to interpret local information (such as the presence of different chemicals or local temperatures and acidity levels) so they can respond appropriately (Should I hug it or eat it or run?). The philosopher Daniel Dennett writes: “Animals are not just herbivores or carnivores. They are… informavores.”  In fact, all living organisms are informavores. They all consume information, and the mechanisms they use for reading and responding to local information—whether they are eyes and tentacles or muscles and brains—account for much of the complexity of living organisms.

Despite the profound differences between Tyrannosaurus rex and an E. coli bacterium, in important respects, life is remarkably unified. All organisms alive today are related genetically. And they share many genetic gadgets, particularly those that, like subroutines in computer software, handle basic housekeeping tasks. In cells, these tasks include jobs such as breaking down food molecules for their energy or their chemical components or moving energy and atoms around. This is why, if you zoom down to the level of cells, it’s hard to distinguish between a human being and an amoeba. 

In March 1968, just before he was assassinated, Robert Kennedy described the limitations of an economy devoted to never-ending growth in gross national product: The Gross National Product counts air pollution and cigarette advertising, and ambulances to clear our highways of carnage.… It counts the destruction of the redwood and the loss of our natural wonder in chaotic sprawl.… Yet the GNP does not allow for the health of our children, the quality of their education, or the joy of their play. It does not include the beauty of our poetry or… the intelligence of our public debate or the integrity of our public officials.… It measures everything, in short, except that which makes
life worthwhile.

First you have to notice that, in their experiment, the clock comparison was made AFTER the flight!!! Again each flown clock run at their building tick rate during the flight, ie 1 second per second. The difference in the readings after the flight was due to the flown clocks following a different path through spacetime (compared with the path through spacetime of the stationary clock, which also run at its building tick rate, ie 1 second per second.

You have been told before that atomic clocks perform a similar function to the function an odometer perform in our cars.

Clocks measure elapsed time along a spacetime path <==> Odometers measure elapsed distance along a space path.

So if you have two identical cars with identical odometers and make the two cars go from Chicago to New York, but following different highways, comparing the odometers readings will show different distances even if the two odometers measure 1 km/km.

The trajectories of the flown atomic clocks in the Hafele-Keating experiment were clearly different from the trajectory of the clock at US Naval Observatory.

According to the present invention a beam of
microwaves or radio waves of ultra high frequen-
cy is directed along the path of movement of the
vehicle in the roadway toward the vehicle from
a test station adjacent to the roadway, and a
small part of such microwaves reflected from
the vehicle are received back at the test station,
The reflected waves are mixed with the trans-
mitted waves by the apparatus in accordance with
the invention to provide a beat frequency which
is directly proportional to the speed of the vehicle
along its path. As a speed meter this beat fre-
quency is applied to a frequency meter calibrated
to provide a direct reading of Speed.

The frequency of the beat frequency
components depends upon the Doppler shifts caused by the
relative speeds between the patrol car and the various
objects painted by the radar which cause radar returns.

The illustration above suggests that you can simply measure distances between waves, you don't need to "beat" the waves together.  And when you argue with the mathematicians, they cannot comprehend any way light can hit an object at c+v, where v is the velocity of the target, because they believe light must travel at c for all observers.  With the waves depicted above, each wave hits at c, but the target gets closer and closer.  But, radar guns do not work that way.  According to NASA, a radar gun can theoretically measure the speed of a target with a single photon.  The emitted photon hits the target at c+v which causes the target to emit a new photon back to the gun that oscillates faster than the original photon.  A comparison is then made inside the gun between emitted photons and the returned photon.  The difference in oscillating frequencies (i.e., the "beat frequency") is equivalent to the speed of the target.

I'm going to have to study these patents further to see what they might contain that would be of value in arguments with mathematician-physicists.

Meanwhile, the arguments on the sci.physics.relativity forum continue to rage.  Yesterday, "Paparios" argued that the length of a second does not change when you are traveling very fast.  He wanted evidence of my claim that it does.  So, I provided a link to my web page of Time Dilation Experments.  This morning, amid a heap of other arguments from other people, Paparios wrote to me:

You do not have the slightest idea of what time dilation is. For your
information, Time dilation is a difference in the elapsed time measured by two clocks, either due to them having a velocity relative to each other, or by there being a gravitational potential difference between their locations.

You see the duration of a second DOES NOT change depending upon your speed!!!  What changes is the elapsed measure of the moving clock (see the twin paradox at https://www.cpp.edu/~ajm/materials/twinparadox.html). Both the stationary clock and the moving clock are identical clocks and they both tick at 1 second
per second, period!

Early in the study of special relativity students learn about the phenomenon of time dilation, i.e., that "moving clocks run slow." Those who have properly appreciated the fact that all motion is relative and who have properly appreciated that clocks measure the passage of physical (including biological) time, ought necessarily to experience some mental discomfort at this result. After all when two observers pass each other, the prediction is that both will find the other's clocks to run slower than their own. This might well seem to be impossible on its face and, therefore, to invalidate the entire theory.

The Doppler effect is a function of the relative speed, not the closing speed. The relative speed between the source and the receiver being ZERO, there is NO Doppler effect. You are dumber than a sack of rocks.

Does the operation manual says that if the gun is in a moving truck and if you point the gun at the rear panel you will not get frequency shift?

It says if you point it at ANYTHING that is not moving relative to the gun, then you will get a zero reading.

Does it say that the gun inside the trailer of a moving truck and is point at the back panel of a moving truck you will not get frequency shift?

Maybe it would help to explain that while the distance between the radar gun and the wall of the moving truck does not change, BOTH the gun and the wall of the truck MOVE while the photons are traveling from the gun to the wall.  While the photons are moving toward the front wall, the front wall is moving away from where the photons were emitted, so the photons have to travel further to reach the wall than they would if the gun and wall were stationary.

The photons also hit the wall with less force, since the wall is moving away. As a result, when the atoms in the wall emit return photons, those photons have less energy than the photons emitted by the gun.

When the return photons reach the gun, the gun RECEIVES the photons as energy. The gun compares the energy of the photons it emitted to the energy of the return photons and gets the speed of the wall.

The Doppler Shift is a function of the CLOSING speed, not the relative speed.  The relative speed between the gun and the wall may be zero when both are moving at the same speed in the same direction, but the Doppler Shift results from the photon hitting a MOVING wall.

Ed, let's assume that you can throw a ball @60 mph. Let's also assume that you are in the back of a large box truck, which is traveling down a long straight and level road @ 60 mph. Do you really think that if you threw the ball towards the front wall of that truck that the ball would never get there? Heck, if your thinking was correct the ball would never even leave your hand! What would happen if the truck was going 80 mph, would the ball just smack you in the face? THINK, man, think!

I assure you, Ed, that we could play catch in the back of that truck and have no clue about the truck's speed, or even if it was moving or not, ignoring vibrations..

Correct.  That is because rubber balls work different from photons.
Rubber balls have MASS, photons do not.  Different laws of electrodynamics work with an object that has MASS than with a photon that has NO mass.

Are you claiming that the wall of the truck will NOT move while the
photon moves?

While the radar gun and the wall are not moving, relative to each other, in that frame of reference (the one attached to the truck), the photons ARE MOVING at speed c (according to the second postulate).

You are confusing this with the view an observer on the ground would have of those photons!! 

"you cannot use logic to prove much of anything in science."

Move? Relative to what? Relative to the ground! I keep asking you what makes the reference frame of the ground special, you deny doing so yet you keep doing so! This is in violation of the First Postulate, there are no preferred reference frames, and this includes the earth's surface.

In reality, the truck body is inertial, so all physics in the moving truck work exactly the same as in the parked truck.  In the reference frame of the inertially moving truck, the gun is stationary, the front wall is stationary and the back wall is stationary.  The radar gun will measure a speed of 0 (or no reading).
