I have discussed now lots of errors (in my view) and the result was 
always the same:

the errors are simply denied, the critique was uttered by a crank (me) 
and the case is closed.

But I can provide something new for you to defend:

it is actually a very simple error and belongs to a class called 'non 
sequitur'. (This means 'it does not follow'.)

It is on page 8 in § 3 about 'Theory of the Transformation of 
Co-ordinates ...'

There are two equations in the upper part of page 8, which both describe 
a certain point (x,y,z) in K coordinates, which was '...just attained by 
this wave,...'.

Now the first equation describes the length of the path of a wave from 
the origin to that point by kind of '3d-pythagoras':

x² +y² +z² = c²*t²

That is certainly true and not particularily interesting.

The second equation is this
ξ² +η² +ζ² = c²* τ²

This is the same point in coordinates from k.

This is also not very spectacular, even if the coordinate system k is 
moving and the equation does not make any attempt to compensate that 
movement. (Actually only Latin variable names are exchanged for small 
Greek letters.)

But for a single point it is not real necessary, if the coordinate 
systems K and k coincide for that instant in time.

But from this 'calculation' Einstein had drawn this conclusion:

"The wave under consideration is therefore no less a spherical  wave 
with velocity of propagation c when viewed in the moving system.  "

And this does not follow and is also wrong, because a spherical wave in 
motion gets red- or blueshifted, hence would not qualify as 'spherical' 
any more.

But more imprtant is, that the conclusion is not justified by the 
'result' of his 'calculation', because the same point (x,y,z) was meant 
and no wave whatsoever.
