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

Einstein=E2=80=99s June 1905, paper is known as Special Theory of Relativity? The reference to this paper

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=E2=80=99 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

=E2=80=9C 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=E2=80=99s Sep. 1905 derivation predicts that when Light Energy is emitted, MASS OF BODY INCREASES?

BRIEF

Einstein has speculated E=3D =CE=94m c2 from L=3D =CE=94m 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=E2=80=99s 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.For details

AJAY SHARMA : In this paper Einstein derived a relationship between Light energy emitted (L) and corresponding decrease in mass (=CE=94m =3D Mb-Ma ) as L =3D ( Mb-Ma)c2 or Mb=E2=80=93Ma =3D L/c2 From here Einstein speculated E=3Dmc2 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 (=CE=94m) of body.

2=2E Under which conditions Einstein derived this equation L =3D =CE=94mc2 ?AJAY SHARMA: In Einstein=E2=80=99s derivation , there are four variables i.= e=2E

(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 =3Dmc2 and speculated from it E=3Dmc2

(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=E2=80=99s derivation is OK. The result is When body emits light energy, its mass decreases i.e. L =3D ( Mb-Ma)c2

It is correct.

3=2E 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 =3D Final Momentum The velocity of recoil of gun is determined by this method. Einstein has considered first case ONLY.

4=2E 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 =CE=94m =3D L /c2 or Ma ( mass of body after emission) =3D Mb ( mass of body before emission) =E2=80=93 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=2E Which is mathematical equation which follows from Einstein=E2=80=99s 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=E2=80=99s 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=E2=80=99s 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

=CE=94 m =3D Mass of body before emission (Mb)=E2=80=93Mass of body after e= mission (Ma) =3D =E2=80=93 0.004L/cv + L/c2 (16) or Ma =3D 0.004L/cv =E2=80=93 L/c2 + Mb Thus Mass of body after emission of light energy (Ma) =3D Positive Quantity + Mass of body before emission. Hence mass Increases, when light energy is emitted.

It is not CORRECT prediction FROM Einstein=E2=80=99s derivation.

Third Post Why Einstein=E2=80=99s Sep 1905 derivation CONTRADICTS Law of Conservation of Matter?

---------------------------------------------------------------------------=

-------------------------------------------- Why Einstein=E2=80=99s 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

=E2=84=93* =3D =E2=84=93{1 =E2=80=93 v cos =CF=86/c } /=E2=88=9A[1 =E2=80= =93 v2 /c2] (1) =E2=84=93* is light energy measured in moving in frame and =E2=84=93 is ene= rgy 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

(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 =3Dmc2 or E=3Dmc2

(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=E2=80=99s 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 =E2=80=98s 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=E2=80=99S SEP. 27 1905 DERIVATION DOES NOT WORK WELL. You have commented about sign CHANGE it follows from Einstein=E2=80=99s 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=E2=80=99s Sep 1905 derivation is true under special conditions only. This is the THEME of the paper. References
