Default Galileo (NOT Einstein) is inventor of Second postulate of Relativity



Galileo (NOT Einstein) is inventor of Second postulate of
Relativity

Einstein’s June 1905, paper is known as Special Theory of
Relativity?
The reference to this paper

[Only registered users see links. ]

In this paper Einstein stated two postulates and here we will discuss
the second postulate.
Part I
Second postulate of Special Relativity as re-stated by
Einstein
(i) “The laws by which the states of physical systems undergo change
are not affected, whether these changes of state be referred to the one
or the other of two systems of co-ordinates in uniform translatory
motion”.

It refer to that law of physics are the same, if two systems or
observers are UNIFROM MOTION (zero acceleration).
I t is well known that in this paper Einstein did not give any REFRENCE
to the existing literature, which implies that all this postulate is
his work .
Part II
Galileo is inventor of Second postulate of special Relativity.
Galileo has given second postulate of Special Theory in his book
Galileo’ Dialogue Concerning the Two Chief World Systems),
Ref.
Galileo, G. 1632, Dialogues concerning the two chief world systems,
trans. S.Drake, 2nd edition 1967, University of California Press.
For this book was published by Galileo in 1632 and was persecuted for
this book.
Galileo quoted an example in the Dialogue [14] , that if a ship is
moving with uniform velocity then from motion of fish in bottle one can
not judge that whether ship is moving with uniform velocity or at rest.
Thus Galileo stated

“ the mechanical laws of physics are the same for every observer
moving uniformly with constant speed in a straight line".

It refer to that law of physics are the same, if two systems or
observers are UNIFROM MOTION (zero acceleration).
The Einstein has simply re-stated in 1905, the existing in the
literature since 273 years. It is against ethics of research. Einstein
should have given due credit to Galileo. Even at this time it I not too
late to honour Galileo for basics of Special Theory of Relativity.

Even Pope John has pardoned Galileo in 1992 for the book, he was
persecuted.

Which mathematical equation from Einstein’s Sep. 1905 derivation
predicts that when Light Energy is emitted, MASS OF BODY INCREASES?
----------------------------------------------------------------------------------------------------

Which mathematical equation from Einstein’s Sep. 1905
derivation predicts that when Light Energy is emitted, MASS OF BODY
INCREASES?

BRIEF

Einstein has speculated E= Δm c2 from L= Δm c2 in his Sep 1905
paper. This derivation ( under SPECIAL CONDITIONS) predicts that when
Light Energy is emitted mass of body decreases. It is true. But the
same derivation under general conditions ALSO predicts that when body
emits light energy its mass must increase. It is inconsistent
prediction from Einstein’s derivation and contradiction of Law of
Conservation of Matter or Energy. Einstein did not discuss this aspect
in his work. This aspect is highlighted here.

USA)

1. What is Einstein’s Sep 1905 paper in few words?.

AJAY SHARMA : In this paper Einstein derived a relationship between
Light energy emitted (L) and corresponding decrease in mass (Δm =
Mb-Ma ) as
L = ( Mb-Ma)c2 or Mb–Ma = L/c2
From here Einstein speculated E=mc2
Practically, Einstein considered a body at rest emitting light energy.
Einstein measured the magnitude of light energy in a moving system. And
then he derived a relation between ENERGY EMITTED (L) and DECREASE IN
MASS (Δm) of body.

2. Under which conditions Einstein derived this equation L = Δmc2 ?

AJAY SHARMA: In Einstein’s derivation , there are four variables i.e.

(a) Number of light waves emitted by body
(b) Magnitude of energy of light waves
(c) Angles at which waves are emitted by body
(d) Velocity of measuring system w.r.t. body emitting light energy.

Einstein took SPECIAL CONDITIONS to derive L =mc2 and speculated from
it E=mc2

(a) Einstein took , Just two light waves
(b) Energy of light wave is equal
(c) Waves are emitted in opposite directions
(d) Velocity measuring system w.r.t body is in classical region.

Thus under these conditions Einstein’s derivation is OK. The result
is
When body emits light energy, its mass decreases i.e. L = ( Mb-Ma)c2

It is correct.

3. What about Law of Conservation of momentum?

AJAY SHARMA : After emission of light energy body
(i) May remain at rest.
(ii) May tend to move
(iii) May move apparently or visibly
the law of conservation of momentum is always obeyed. The velocity of
recoil can be calculated by applying equation,
Initial Momentum = Final Momentum
The velocity of recoil of gun is determined by this method.
Einstein has considered first case ONLY.

4. Which is the mathematical equation obtained by Einstein in Sep 1905
paper which predict that
When light energy is emitted, mass decreases?

AJAY SHARMA: The final equation in this regard is
Δm = L /c2
or Ma ( mass of body after emission) = Mb ( mass of body before
emission) – L/c2
Thus mass of body decreases when light energy is emitted.
Einstein has derived this equation under SPECIAL CONDITIONS by
considering two light waves of equal energy( 0.5L each ) , emitted in
opposite directions etc.

5. Which is mathematical equation which follows from Einstein’s
derivation and implies that
when Light Energy is Emitted mass of body Increases?

AJAY SHARMA There are numerous equations to this fact
which follows from Einstein’s Sep 1905 derivation and predict that
when
Light Energy is emitted, Mass of Body Increases.
It is contradiction of LAW OF CONSERVATION OF MATTER OR ENERGY.

One case is e.g. when body emits TWO LIGHT WAVES of energies 0.501L
and 0.499L , emitted in OPPOSITE DIRECTIONS. Thus all conditions are
same as that in Einstein’s derivation except magnitude of Light
energy (Einstein has taken energy equal to 0.5L each).

Exactly repeating the calculation as done by Einstein in Sep 1905 paper
we get

Δ m = Mass of body before emission (Mb)–Mass of body after emission
(Ma)
= – 0.004L/cv + L/c2
(16)
or Ma = 0.004L/cv – L/c2 + Mb
Thus
Mass of body after emission of light energy (Ma)
= Positive Quantity + Mass of body before
emission.
Hence mass Increases, when light energy is emitted.

It is not CORRECT prediction FROM Einstein’s derivation.


Third Post
Why Einstein’s Sep 1905 derivation CONTRADICTS Law of
Conservation of Matter?
-----------------------------------------------------------------------------------------------------------------------
Why Einstein’s Sep 1905 derivation CONTRADICTS Law of Conservation
of Matter ?
Part I
Reason for this incorrect deductions.
The central equation in Einstein derivation is very complex .
(i) The basic equation Einstein used is

ℓ* = ℓ{1 – v cos φ/c } /√[1 – v2 /c2] (1)
ℓ* is light energy measured in moving in frame and ℓ is energy
measured in rest frame. Einstein has given eq.(1) in his June 1905
paper, known as Special Theory of Relativity and called eq.(1) as
Doppler principle for any velocities whatever. Link for paper of
Special Theory of Relativity
[Only registered users see links. ]
(ii) Thus there are many variables in derivation.

(a) Number of light waves
(b) Magnitude of energy of light waves
(c) Angles at which waves are emitted
(d) Velocity of measuring system w.r.t. body emitting light energy.

Einstein took special conditions to derive L =mc2 or E=mc2

(a) Einstein took , Just two light waves
(b) Energy of light wave is equal
(c) Waves are emitted in opposite directions
(d) Velocity measuring system w.r.t body is in classical region.

Thus under these SPECIAL conditions Einstein’s derivation is OK. The
result is
When body emits light energy , its mass decreases.

Part III

Experimentally law of inter conversion of mass energy holds good in all
cases. Theoretically large number of cases is possible (Einstein ‘s
derivation is valid under these conditions also).
(p) Body may emit large number of waves
(q) The waves may be emitted at different angles.
(r) The waves may have different energies.
(t) Velocity may be in relativistic region.

THUS UNDER GEENRAL CONDITIONS EINTEIN’S SEP. 27 1905 DERIVATION DOES
NOT WORK WELL.
You have commented about sign CHANGE it follows from Einstein’s
derivation, hence it has limitation.
If you think , I have INCORRECTLY induced it , let me know. Write down
the correct equations for the readers.

So Einstein’s Sep 1905 derivation is true under special conditions
only. This is the THEME of the paper.
