Hi:

Doesn't the complete and utter lack on interest in and response to your
posts tell you ANYTHING? Please confine this to sci.astro or some other
group where it will be welcome.

Your "theories" are NOT welcome on sci.astro.amateur.


Not only is your drivel not welcome on sci.astro.amateur, we understand
your vain attempts to garner hits on your name and drivel so that you
can claim you had an intelligent discussion of physics and Einstein's
theories on your blog. I work with a lot of Indian scientists and am
normally impressed with their understanding of maths and physics and
the education system in India. You are living proof that not every one
can be educated

----------- Dr Robert Pasken , Kindly refer to you
post--------------------

Kindly justify YOUR SELF .

rpasken@xxxxxxxxxxx , You have made comments that Momentum is not
Conserved in my PAPER. It is not CORRECT. It is explained in 100 Years
of E=mc2

See how Momentum is conserved in my paper. All references are given in
the end.
Part I
General meaning , explained in 11th class Physics.
The law of momentum conservation,
* In an isolated system, the momentum of system must be conserved.*

Mathematically implies that
Initial Momentum = Final Momentum
mu=mv (1)
As mass remains same in classical mechanics.
So u=v
which is Newton’s First law of motion.

Application of momentum conservation.
When body emits energy ( in this cases light energy)
then it recoils .Thus it is used to calculate the velocity of recoil.
It can be applied to following two cases.

------ Light bullet fired from TOY Gun, system remains at rest.
( body does not recoil with noticeable velocity, it tends to recoil)
The velocity cam be calculated but may be of the order of
1/100000000000000000000000000000000000 m/s or 10-^40m/s
This case resembles with Einstein’s two waves of equal energy emitted
in opposite directions.

-----Shot fired from gun, gun moves backward.
the velocity can be calculated from conservation of momentum i.e.
initial momentum =final momentum
Vrecoil = mv/M ~ 5m/s (say)
Thus after emission of energy BODY MAY REMAIN AT REST OR MOVE, the
Momentum is Conserved. It is basic physics of 11th standard.
If some one does not want to understand this then it his problem.
Einstein did all calculation under Classical conditions of velocity (v
<<c, her v is relative velocity between two systems i.e. system in
which body emits light and second system in which energy is measured.

Part II
The law of conservation of momentum is obeyed in my paper.

When two waves are emitted. The body recoils with velocity v , with
magnitude of the order of 10^-32 m/s i.e.
V (recoil)=1/10000000000000000000000000000000000000000000000000
It can be easily calculated.

When two waves of different energies are emitted. If body emits two
light waves of slightly different energies i.e. 0.5001L and 0.4999L
(Einstein has used light waves of energy 0.5L and 0.5L) in opposite
directions. Now using the law of conservation of momentum, it can be
easily justified that in this case body remains at rest.
Let the body of mass 10kg emits light energy in two waves in visible
region equal to 7.9512×10^-19 J, this energy corresponds to TWO light
waves in visible region having wavelength 5000ºA or energy, 2hc/λ or
7.9512×10^-19 J.
Let towards the observer the body emits light energy 0.5001L i.e.
3.97639512×10^-19 J i.e. will have momentum ( p1 = E/c)
1.32546504×10^-27 m/s.
Secondly, the body emits light wave of energy 0.4999L i.e.
3.97480488×10^-19 J, away from the observer (φ= 180º) i.e. will have
momentum ( p2 = E/c) 1.32493496×10^-27 m/s. Let us assume that when
the body emits light waves of energy and moves (if it actually does)
with velocity Vb , then according to law of conservation of momentum we
get
0 = p1 +p2 +MbVb or Vb = -(p1 +p2) /Mb = –5.3×10^-32 m/s (2)
0 = p1 +p2 +MbVb or Vb = -(p1 +p2) /Mb = –5.3×10^-32 m/s (3)
Thus conservation of momentum requires that body should move with
velocity –5.3×10^-32 m/s opposite to observer. Thus body will tend
to move with velocity 5.3×10^-32 m/s ( away from the observer) which
is immeasurably small by all means, hence the body remains at rest. Due
to this uniform relative velocity v of the system (ξ, η, ζ ) will
not change, if body moves then v will vary accordingly.
=========Einstein’s Sep 1905 paper===========
The first and basic equation in Einstein’s paper is
l* = l{1 – v/c cos φ } /√[1 – v2 /c2] (1)
In eq.(1) v is the relative velocity between light emitting body and
the measuring system i.e. system (ξ, η, ζ ). If body moves after
emission with velocity v’ away from the observer, then relative
velocity will be v+v’ (say V). Thus in this case eq.(1) becomes
ℓ* = ℓ{1 – (v+v’) cos φ/c } /√[1 – (v+v’)2 /c2] (1a)
The rest of the calculations remain the same. Thus Einstein’s
derivation is also valid if the body moves, Einstein has considered the
simplest case when velocity v’ is zero (V= v+v’ =v), which is
special case. Also experimentally the law of inter conversion of mass
energy holds good in all possible cases.

Hence you cannot say that LAW OF CONSERVATION OF MOEMTUM IS NOT TAKEN
IN ACCOUNT IN MY PAPER.
It is your MISPERCEPTION.
