Chapter 42: where does it come from? |
In the 1977 printing of the Feynman Lectures, in vol. 2 I find a Chapter
42 not present in the first printing, dealing with General Relativity.
Sand's foreword however has remained the same, and no mention is made of
that chapter.
Does someone know the history of Chapter 42?
Thanks

Which part of "c+v" in Einstein's paper did you not understand?
For quotations, reference
"On the Electrodynamics of Moving Bodies" - by Albert Einstein.
online version
http://www.fourmilab.ch/etexts/einstein/specrel/www/
Declare v > 0.
Einstein defines
'the ``time'' required by light to travel from A to B equals the
``time'' it requires to travel from B to A.'
and formally states
"the ray moves relatively to the initial point of k [ aka A ], when
measured in the stationary system, with the velocity c-v, so that
x'/(c-v) = t"
which leads directly to
the ray moves relatively from the point of reflection [aka B] , when
measured in the stationary system, with the velocity c+v, so that
x'/(c+v) = t
and is evidenced in the equation
½[tau(0,0,0,t)+tau(0,0,0,t+x'/(c-v)+x'/(c+v))] = tau(x',0,0,t+x'/(c-v))
Hence:
x'/(c-v) = x'/(c+v)
from which we have a (formal mathematical) proof by contradiction that
v > 0, which is against the definition.
QED.
