#577061 — Time définition (Tr,Tapp, Tp, To)

SubjectTime définition (Tr,Tapp, Tp, To)
Message-ID<bosKOoBUhkjQxVqhvYQ4-5bF77U@jntp>
A question that can be asked is that of the difference between the real 
time Tr and the proper time Tp.

Is it the same thing?

If we study the reference frames in uniform relativistic motions, it 
immediately appears that it is the same thing.

The real time taken by a twin to reach a solar system at 0.8c located at 
12 ly, is 9 years.

Tr=9 years.

But it is also its own time.

Tp=9 years.

The observable time is To=15 years.

And the apparent time is Tapp=27 years.

All this is very simple and is no longer to be discussed.

But what about in accelerated repositories?

Can we say, in this frames, that Tp=Tr?

Why do you persist in using incorrect translations, improper
terms like "repository", when you've been advised they are
wrong and the correct one has been provided to you?

“Real time” is another concept and term that you invented out of ignorance, 
so only you can know.

Please try to understand my question before answering.
If you don't understand my question, don't answer it.
The question I am asking here is not simple, and is not, I admit, easily 
understandable for an average mind, or even a consistent IQ.
It is impossible to answer what I have just said without at least giving 
it some thought.

No sir. If you spout nonsense, you’re going to get called on it.

You have not earned the right to speak whatever you wish and to have people
pay attention to it, other than to note that you are spouting nonsense.

I can understand that you are suffering from the delusion that what you
are saying would make sense and could be understood, but that is not so.

If we consider that an instantaneous speed corresponds to an infinitesimal 
strip of space traversed by the rocket at a given instant, it comes that 
we can consider that, on this strip, the acceleration being negligible, we 
can admit that the 'we are in the case of a relation 
To=Tr.sqrt(1+Vr²/c²)
And therefore dTo=dTr.sqrt(1+Vr²/c²) inside this band.
In short, this means that I have the right to consider that Tr=Tp during 
this brief instant.
And that we can consider that the long evolution of the rocket in an 
accelerated medium is only a coherent sequence of small quantities of 
uniform speeds where, always, Tp=Tr.

I therefore do not dissociate Tr from Tp in accelerated repositories.

Contrary to what relativist scientists seem to do.

On the other hand, they seem to confuse something else, that is to say Vr 
and Vr+dVr
and simplify Vr+dVr by Vr in the equations.

But are we right to do this?

Is it the same thing?

Aren't we confusing what you can do with a turnip with what you can do 
with a carrot?

I explain:
Yes, I can consider that Tr=Tp, that is to say replace the real time by 
the proper time in the equations, since we can consider that the rocket 
evolves not in an accelerated way friends according to an infinity of 
constant speeds always infinitesimally greater than the previous speed. 
BUT I say nothing more about these speeds between them. And I affirm that 
these are not the same speeds.
I will therefore not go further than setting Tp=Tr=To/sqrt(1+Vr²/c²).

I absolutely do not set Vr+dVr=Vr and I do not simplify 
To=Tr.sqrt(1+(Vr+dVr)²/c)² to
To=Tr.sqrt(1+Vr²/c²)

Do you understand the difference?

Please have two or three cups of coffee before replying to this post.

In short, I do (as usual), just the opposite of what they do.

Am I wrong?

Am I a bad terrorist?

A thug, a bandit?

Simply because I want to clearly understand what I'm doing when I make a 
relativistic description.

A good start would be to take time to follow a course on Relativity.

This course is quite a good one:

But we are not.  And this can be easily shown.
 
If two events e₁ = (t₁, x₁, y₁, z₁) and e₂ = (t₂, x₂, y₂, z₂) are connected 
by a light signal, then there are two ways by which the spatial distance 
between them can be calculated.

One is the Euclidean distance given by the square root of the sum of the 
squared differences between their spatial Cartesian coordinates (actually 
just the multiple application of the Pythagorean theorem):

  Δs = √((x₂ − x₁)² + (y₂ − y₁)² + (z₂ − z₁)²) =: √((Δx)² + (Δy)² + (Δz)²).

The other is by the time that light requires to travel the distance:

   c = Δs/(t₂ − t₁) =: Δs/Δt.

⇔ Δs = c Δt.

As these distances are equal, we have

  c Δt     = √((Δx)² + (Δy)² + (Δz)²)

or (to get rid of the square root)

  c² (Δt)² = (Δx)² + (Δy)² + (Δz)².

  [From here on I will omit the parentheses around the squared quantity,
   as is customary.]

⇔        0 =  Δx² + Δy² + Δz² − c² Δt²
⇔        0 = −Δx² − Δy² − Δz² + c² Δt²
⇔        0 = c² Δt² − Δx² − Δy² − Δz².

If the two events are not identical, then Δt ≠ 0 and we may divide by Δt², 
so we can extract it without an accident:

         0 = Δt² [c² − Δx²/Δt² − Δy²/Δt² − Δt²/Δz²]
⇔        0 = Δt² [c² − (Δx²/Δt² + Δy²/Δt² + Δz²/Δt²)].

The sum there is nothing else but the square of the velocity, which (as 
velocity is a vector) is equal to the square of the norm (or magnitude) of 
velocity v⃗ = (v_x, v_y, v_z), the speed v:

⇔        0 = Δt² [c² − ([Δx/Δt]² + [Δy/Δt]² + [Δz/Δt]²)]
           = Δt² [c² − (v_x² + v_y² + v_z²)]
           = Δt² (c² − v²).

We may further extract c² (≠ 0), divide by it, and take the square root:

         0 = Δt² c² (1 − v²/c²)
⇔        0 = Δt  (1 − v²/c²)
⇔        0 = Δt √(1 − v²/c²).

Now if Δx, Δy and Δz are not all equal to 0 (length units), then Δt is the 
time that elapsed in a reference frame in which we said that whatever 
connected the events was in motion.  If we say that it was not in motion, 
i.e. Δx = Δy = Δz = 0 (length units), i.e. in the rest frame of the "moving" 
object, the elapsed time *then* is not necessarily the same (in fact, we 
will find that is not ever the same).

We call it the *elapsed _proper_ time* because it is measured by a clock at 
rest in that frame, and introduce for it the symbol Δτ:

         0 = c² Δτ².

If we divide by c² and take the square root again, then we have two 
quantities which are both equal to 0; so they are equal to each other, and 
we can write

        Δτ = Δt √(1 − v²/c²).    (1)

    [And NOT “To=Tr.sqrt(1+Vr²/c²)”.  The sign in your formula is WRONG.]

    [In passing, we note that if a clock traveling with a light signal would
     measure that no time at all would have elapsed.  Sometimes this is
     worded in popular-scientific sources as “photons/light do(es) not
     experience time”.]

It is useful to define the *Lorentz factor* (named so because it appears in 
the *Lorentz transformation* which is named after Hendrik Antoon Lorentz who 
first proposed it)

         γ ≔ 1/√(1 − v²/c²),    (2)

and we can write eq. (1) as

        Δτ = Δt/γ.

From eq. (2) we can see that if v ≠ 0, then γ > 1.

From this we can then see that the elapsed proper time Δτ and the elapsed 
*coordinate time* Δt are usually not equal: If v ≠ 0, then the elapsed 
proper time – the time measured to have elapsed by a clock in relative 
motion – is shorter than the elapsed coordinate time – the time an observer 
who considers that clock to be in motion measures according to clocks at 
rest relative to them:

        Δτ < Δt.

But the (Galilean) principle of relativity says that every observer can 
consider themselves to be at rest, and clocks that are not moving relative 
to them to be at rest.  So this *time dilation* effect has to be and 
actually is symmetric: An observer that is considered to be moving by the 
first observer will say the same about the clocks (and the time) of the 
first observer when they compare it with their own clock (and own time).

The German term for “proper time”, which I think was coined first, is 
actually „Eigenzeit“ which literally translates to “own time” (cf. terms 
like “eigenvector”, “eigenvalue”, and “eigenfunction” which made it from 
German mathematics to English-speaking mathematics literally instead).

In a (Minkowski/spacetime) diagram the connection of two events by a light 
signal can be illustrated as follows:

     c t
     ^
     :       Δx = c Δt
  t₂ +     .----------. e₂
     :     :        .'
     :     :      .'
     :  Δt :    .' Δτ = Δs = 0 (here)
     :     :  .'
     :     :.'
  t₁ +  e₁ '
     :  
     '-----+----------+-------> x
           x₁         x₂
   
Note that there *seems* to be a contradiction here: Δτ seems to be longer, 
not shorter, than Δt, and that it should be given by √(Δx² + Δt²), and it 
certainly does not look like 0 for light.  But we have seen that this is NOT 
so.

The reason is that spatial dimensions and temporal dimensions must be 
treated *differently*: it is a *pseudo*-Euclidean metric that must be used 
to determine Δτ, namely Δs² = c² Δτ² = c² Δt² − Δx² (assuming that Δy = Δz
= 0).

If the two events are not connected by a light signal, but e.g. by a 
material object (v < c), then the (timelike) *worldline* that does is 
steeper (as less distance is traveled in the same coordinate time):

     c t
     ^         c Δt
     :     ,-----'----.   v = c
     :        Δx        .'
  t₂ +     .-----. e₂ .'
     :     :    :   .'
     :     : Δτ:  .'
     :  Δt :  : .' 
     :     : :.'
     :     ::
  t₁ +  e₁ '
     :  
     '-----+-----+-----------> x
           x₁    x₂

We can see that with this sign convention for this *timelike* worldline we 
have Δs² > 0.  Whereas for events that are not causally connected (if the 
speed of light in vacuum is the maximum speed), the *spacetime interval* is 
*spacelike*, Δs² < 0.

For those for whom this is not obvious (IIRC, it wasn’t to me just a few 
years ago, before I studied Physics/Mathematics): Consider that the distance 
between two points in 3D space Euclidean space, Δs, is given by the 
Pythagorean theorem (or: the Theorem of Pythagoras)

  (Δs)² = (Δs')² + (Δz)²,

where Δs' is the length of the orthogonal projection of Δs (or rather the 
vector of which Δs is the norm/length) onto the (parallel to the) x–y plane, 
itself given by the Pythagorean theorem:

  (Δs')² = (Δx)² + (Δy)²,

so

  (Δs)² = (Δs')² + (Δz)² = (Δx)² + (Δy)² + (Δz)². ∎

This means that the Pythagorean theorem can be generalized to higher 
dimensions, i.e. n-dimensional Euclidean spaces (where coordinates are 
measured parallel to straight coordinate axes that are all perpendicular to 
each other), and one can define the *Euclidean norm* (or 2-norm) of a vector
v⃗ = (v₁, v₂, …, vₙ):

  ‖v⃗‖₂ ≔ √[∑_i (v_i)²].

Your problem is simple.
You are ignorant of calculus.

See 2.3. in the following article.
It shows how you can handle accelerated motion.

But you will never learn, of course.

 No, no, I don't think that's the problem.

The problem is simply that I've always liked figuring things out for 
myself, and not just repeating them.

I was born like this. With what Descartes called "methodical doubt".

Take the case of the newspaper. Have you ever read a newspaper? It is 
April 15, 1912 in the morning, and you read in the newspaper: "The liner 
Titanic sank last night after hitting an iceberg".
What are you doing, Paul?
You swallow it.
I have this superiority over the average man that I don't swallow it.
That's all.

And I'm the one who's right, not seven thousand other humans who 
mindlessly swallow all the bullshit they're told.

The theory of relativity, yes.

Of course I admit it and defend it.

But not just any and not said anyhow.

Your way of figuring calculus out for yourself
isn't very successful.

Not to learn calculus.

I see. Mathematicians and physicists are idiots
since they 'swallow' calculus.

BTW, the number of humans who master calculus is very
much higher than seven thousand.

I understand that you will never be among them,
because you know you are right when calling it bullshit.

Stop fucking, stinker. When your idiot guru told you
that 2000 years old math is false - you simply swallowed
it. Your invoking the basic math authority is only funny
now.

No, I'm not saying that.
I think human intelligence is relatively decent in general.
I don't think the problem of mathematicians or physicists is really a 
problem of intelligence.
I think it's more of a man's problem.
When Poincaré states the theory of relativity, we manage to give the 
Nobel to Einstein (the guy who copied the patents in Bern). When Diesel 
goes to England to discuss his engine patent, we find his body floating in 
the English Channel. Etc...
I don't think it's an intelligence issue at all.
Physicists and mathematicians are men. That's mostly their problem.

Yet you stated that those who "swallow" the "bullshit" of calculus are 
idiots.  Please clarify.

Einstein never received any Nobel for relativity.

C'est ce que je dis.

Quand on a voulu donner le prix Nobel pour la théorie de la relativité 
restreinte à Einstein, et pas à Poincaré, le véritable père de toute 
la théorie, théorie qu'Einstein de son bureau des brevets de Berne avait 
recopié point par point, les français, écoeurés se sont levés et ont 
quitté la salle.

Ils sont alors revenus sur leur décision, mais ont tout de même donné 
le prix Nobel à Einstein pour un papier ridicule traitant de l'effet 
photo-électrique.

Déjà à cette époque, les prix Nobel ça puait la rage.

Obama et Arafat n'avait pas encore celui de la paix, mais...

C'est un métier, la politique.

For those not fluent in French, what Hachel/Lengrand is claiming here
is that while the Nobel Committee was about to attribute to Albert
Einstein a prize in physics for Special Relativity the whole team
of French representation (whatever it means) left the room in anger
because Einstein did plagiarize Poincaré's work.

This is outrageously FALSE. There is absolutely nothing Hachel/Lengrand
can present as an evidence for this.

The main reason everyone ignores Lengrand's posts on fr.sci.physique
these days is because he has the habit to make up idiotic stuff of
this kind. After 20+ years of this despicable behaviour, people gave
up on considering this disgusting person, except as laughing stock.

Then this kook claims that Einstein papers on photo-electric effect
is "ridiculous". Quite a pathetic claim from a charlatan who fails
not only on understanding SR (or any kind of physics btw), but also
complex numbers or calculus.
