Home Is Where The Wind Blows

An immortal fumble by Aleksandar Vukelja (15-Mar-2005)

I must give them a short lesson.
I faced a really strange attempt by several posters yesterday to 
disprove my ideas, published at http://www.masstheory.org 

As these gentlemen do not know SRT, but claim otherwise, I must give 
them a short lesson. 

The SRT lesson to relativity supporters 
------------------------------­---------- 

Any number of points in a still inertial system x1, x2, x3,... xn share 
the same time t. Any number of points in an inertial system moving 
uniformly x1', x2', x3',... xn' share the same time t'. 

I insist that this is the Special Relativity standpoint - it allows for 
different inertial systems to have different measures of space and 
time, but entire inertial system shares "single" time. 

This allows us to write Lorentz equations in the form 

    Dx' = Dx sqrt(1-v^2/c^2) 
    Dt' = Dt / sqrt(1-v^2/c^2) 

I found now on the web virtually the same explanation for this that I 
gave to Dirk yesterday. Please visit the 
http://hyperphysics.phy-astr.g­su.edu/hbase/relativ/tdil.html and tell 
me how is length contraction and time dilation formula explanation 
different from the explanation I gave in the yesterday's thread 
(subject: origin of inertia). I gave equations, which are standard 
physics textbook simplified Lorentz transformations. 

What's the problem then? 
------------------------ 

Dirk Van de Moortel has introduced a view that each point in THE SAME 
inertial system has its own time (x1, t1), (x2, t2), ... etc. And 
insists that this is the SRT point if view. 

His interpretation, supported by several other posters, is that in 
original Lorentz equations one can place a "delta" in front of every 
coordinate (which assumes that each point x1, x2,... has its own time 
t1, t2, etc. both for primed and non-primed coordinates), like this: 

    Dx' = g ( Dx - v Dt ) 
    Dt' = g ( Dt - v Dx / c^2 ) 
    with g = 1/sqrt(1-v^2/c^2) 

Which results in claim that the example 

    Dx' = 1/2 Dx 
    Dt' = 2 Dt 

can only be valid for 

    Dx' = Dt' = Dx = Dt = 0. 

Solution 
-------- 
Come on people, there must be knowledgeable people reading this. 
Regardless of my view that entire SRT is a historic joke of human kind, 
or perhaps YOURS that relativity is valid theory, NO supporter of 
relativity should defend favorite theory by misrepresentation. Share 
your opinion!
