[escepticos] Inercia como interacción, y no como propiedad intrínseca de la materia

["Javier Susaeta" <avusrb@...>]

Hola...

Aunque este texto ya lo mandé hace unos días en una respuesta a Eloy, quiero 
mandarlo otra vez bajo el nuevo 'subject' para agrupar los 'argumentos de 
autoridad' bajo un mismo 'Asunto'.

Escribe Einstein en 'The Principle of Relativity'
Princeton
Science Library Edition, 1988, pág 100:

(...)the theory of relativity makes it appear probable that Mach was
in the
right road in his thought that inertia depends upon a mutual action
of
matter. For we shall show in the following that, according to our
equations,
inert masses do act upon each other in the sense of the relativity
of
inertia, even if only very feebly. What is to be expected upon the
line of
Mach's thought?

1. The inertia of a body must increase when ponderable masses are
piled up
in its neighbourhood.

2. A body must experience an accelerating force when neighbouring
masses are
accelerated, and in fact, the force must be in the same direction as
that
acceleration.

3. A rotating hollow body must generate inside of itself a "Coriolis
field"
which deflects moving bodies in the sense of the rotation, and a
radial
centrifugal field as well.

We shall now show that these three effects, which are to be expected
in
accordance with Mach's ideas, are actually present according to our
theory,
although their magnitude is so samll that confirmation of them by
laboratory
experiments is not to be thought of. (...)
