----------

L'excellent Jean-Pierre Messager veut en découdre avec moi.

J'apprécie.

J'aime les challenges.

Il dit que mon équation n'est pas bonne.

a'= a*(2*sqrt(1+(a*To/c)^2)-1)^(-3/2)

Il propose, à la place, si j'ai bien compris:

a' = a * [ 1 + (a*t/c)^2 ] ^ (-3/2)

C'est à dire, disons le clairement, employons les termes forts, et
baissons nos pantalons devant les dames :
a' = a * [ 1 + (a*Tr/c)^2 ] ^ (-3/2)

C'est ça, ou j'ai rêvé?

C'est ça que tu dis, mon Jean-Pierre chéri quand il est gentil?

Mais c'est pas souvent, il aime pas être gentil.

C'est ça que tu dis, mon amour chéri, ou c'est moi qui me trompe?

--------

The excellent Jean-Pierre Messager wants to do battle with me.

I appreciate.

I like challenges.

He says my equation is wrong.

a'= a*(2*sqrt(1+(a*To/c)^2)-1)^(-3/2)

It proposes, instead, if I understood correctly:

a' = a * [ 1 + (a*t/c)^2 ] ^ (-3/2)

That is to say, let's say it clearly, let's use the strong words, and
let's drop our pants in front of the ladies:
a' = a * [ 1 + (a*Tr/c)^2 ] ^ (-3/2)

Is that it, or was I dreaming?

Is that what you say, my darling Jean-Pierre when he's nice?

But it's not often, he doesn't like to be nice.

Is that what you say, my darling love, or am I wrong?

Avec les définition usuelles, cf. papier de Paul Andersen.

cf. https://paulba.no/pdf/TwinsByMetric.pdf

déjà sûrement pas a' ("prime" indique habituellement une dérivée
même si en physique on préfère le point au dessus ou bien d.../dt),
hors il ne s'agit certainement pas de la dérivée de l'accélération
dont il est question.

La formule a * [ 1 + (a*t/c)^2 ] ^ (-3/2) décrit l'évolution de
l'accélération d'un corps uniformément accéléré, à vitesse nulle
à t=0, partant de x=y=z=0 en fonction du temps mesuré (pour une
position (x,y,z)) à l'instant t du référentiel de départ.

Il faut 5 ou 6 lignes à partir des équations du papier d'Andersen
pour les déduire.

Il s'agit d'une conséquence directe des transformations de Lorentz.

L'équation que tu donnes, si elle correspond à ce que tu as écrit est
correcte, mais elle est de peu d'intérêt.

Elle donne l'accélération variable a' notée dans le référentiel
terrestre en fonction de a (accélération constante dans le référentiel
propre) et en fonction du temps PROPRE de l'objet.

L'intérêt est donc limité.

Il est bien plus logique de s'intéresser à l'accélération observable
(dans le référentiel terrestre) en fonction du temps terrestre To.

Et ça, c'est donné directement par l'équation

<http://news2.nemoweb.net/jntp?6Pt9Jr0_6SAXbEpNjCgi09TyEH0@jntp/Data.Media:1>

Une autre équation que j'ai donnée est celle-ci :

a'= a.(1-Vo²/c²)^(3/2)

Elle donne la correspondance en fonction de la vitesse observable du
mobile dans le référentiel terrestre.

A noter que si je prend l'équation que tu as validé (et si tu l'écris
comme moi), tu as

a' = a * [ 1 + (a*Tr/c)^2 ] ^ (-3/2)

Or, on sait qu'il est licite de poser Vr=a.Tr (en langage Hachel).
et qu'il est également licite de poser Vr=Vo/sqrt(1-Vo²/c²)

D'où a' = a * [ 1 + (Vr/c)^2 ] ^ (-3/2)
et si (1+Vr²/c²)=(1-Vo²/c²)^-1
alors a'= a.(1-Vo²/c²)^(3/2)

Si tu aimes les problèmes, il y a le problème du voyageur de Tau Ceti.
a=10m/s². x= 12 ly.

Quelle sera la vitesse observable de la fusée dans le référentiel
terrestre quand la fusée attendra Tau Ceti?

Quelle sera son accélération mesurable à cet instant dans le
référentiel terrestre?

Je te donne les réponses et si tu ne retrouves pas les mêmes, c'est
qu'il y a une coquille dans tes concepts.

Vo=0.98076c

a'=0.0744m/s² (on passe de 10m/s² au départ à seulement 75 mm/s²
environ en entrant dans le système de Tau Ceti pour le référentiel
terre-Tau Ceti).

C'est bon?

Tu suis?

-------------------

>> a' = a * [ 1 + (a*Tr/c)^2 ] ^ (-3/2)

>> Is that it, or was I dreaming?

> Tr I don't know what it is, so yeah maybe or not. meh.

The equation you give, if it corresponds to what you wrote, is correct,
but it is of little interest.

It gives the variable acceleration a' noted in the terrestrial frame of
reference as a function of a (constant acceleration in the proper frame of
reference) and as a function of the PROPER time of the object.

Interest is therefore limited.

It is much more logical to be interested in the observable acceleration
(in the terrestrial frame of reference) as a function of terrestrial time
To.

And that is given directly by the equation

<http://news2.nemoweb.net/jntp?6Pt9Jr0_6SAXbEpNjCgi09TyEH0@jntp/Data.Media:1>

Another equation I gave is this:

a'= a.(1-Vo²/c²)^(3/2)

It gives the correspondence according to the observable speed of the
mobile in the terrestrial reference frame.

Note that if I take the equation that you validated (and if you write it
like me), you have

a' = a * [ 1 + (a*Tr/c)^2 ] ^ (-3/2)

Or, we know that it is licit to set Vr=a.Tr (in Hachel language).
and that it is also licit to set Vr=Vo/sqrt(1-Vo²/c²)

Hence a' = a * [ 1 + (Vr/c)^2 ] ^ (-3/2)
and if (1+Vr²/c²)=(1-Vo²/c²)^-1
then a'= a.(1-Vo²/c²)^(3/2)

If you like problems, there is the problem of the traveler of Tau Ceti.
a=10m/s². x= 12 ly.

What will be the rocket's observable velocity in the Earth frame when the
rocket is waiting for Tau Ceti?

What will be its measurable acceleration at this instant in the Earth
frame?

I'll give you the answers and if you can't find the same ones, there's a
typo in your concepts.

Vo=0.98076c

a'=0.0744m/s² (we go from 10m/s² at the start to only around 75 mm/s²
when entering the Tau Ceti system for the earth-Tau Ceti reference frame).

Its good?

You follow?

It is exactly what the formula I've provided expresses.

And you can fuck off the rest of your diversion and pull it deep in
you puffy ass. Your formula was wrong. PERIOD.

Va chier Lengrand, tu l'as mauvaise, ais un minimum d'honnêteté et
admet ton erreur.

And, please stop crossposting in groups with different languages, you're
an asshole with NO RESPECT to people.

t in the equation I've provided is likely to be "your To", who knows?
But certainly not "your Tr".

You're making a fool of yourself, Lengrand.

Your equation is ridiculously wrong, you have no derivation anyway.
Time to give up dude.

Oh, stinker Python is opening its muzzle again,
and trying to pretend he knows something.
Tell me, poor stinker, what is your definition of
a "theory" in the terms of Peano arithmetic?
See: if a theorem is going to be a part of a theory,
it has to be formulable in the language of the
theory. Do you get it? Or are you too stupid even for
that, poor stinker?

I think the variable he used was t, not any of your made-up variables.

Now, you can pretend that you do not see those variables. You can decide to
deflect from the fact that the algebraic expression you wrote is incorrect
and has entirely the wrong functional behavior.

What are you going to do when you have made an error? Deny the error and
then continue to make the same error for the next 40 years? Does that sound
like the path of sanity to you?
