You're probably aware of the fact that I have been informed that the
illusion of a cube that is moving past an observer and which appears
to be rotated due to the effects of perspective is reality; that the
cube is rotated and that face ABEF is physically contracted at right
angles to the cube's direction of travel in lieu of simply appearing
to be rotated as a result of a perspective created visual illusion.

I have been informed that a mathematical equation creates reality -
that the square face of side ABCD which the observer sees is not a
square but is a rectangle because that's what the math 'shows' it to
be.

Einstein wrote:-

"As far as the propositions of mathematics refer to reality, they are
not certain,; and as far as they are certain, they do not refer to
reality." (233, 'Ideas and Opinions', Bonanza, 1954)

He also wrote:-

"The idea of the measuring rod and the idea of the clock coordinated
with it in the theory of relativity do not find their exact
correspondence in the real world." (236, 'Ideas and Opinions',
Bonanza, 1954)

The concept of length contraction in STR is a mathematical proposition
which, according to Einstein, does not refer to reality.

Having initially set out to establish the irrefutable validity of
mathematics Bertrand Russel was reluctantly forced to conclude:-

"Mathematics may well be a subject in which we never know what we are
talking about nor that what we are saying is true."

In his article 'The Twin Paradoxes of Special Relativity - Their
Resolution and Implications' (541, 'Foundations of Physics' Vol 19, No
5, May, 1989) Professor Simon J Prokhovnik, at the time of submission
- Head of the School of Mathematics at the University of New South
Wales (Aust.) having furnished an equation in support of his argument
wrote:-

"Note, that I am not saying here that the theory is thereby
necessarily also physically valid...There are plenty of self-
consistent mathematical systems which have scant relevance to physical
phenomena or observations."

In his book 'Relativity - the Special and General Theory' Einstein
wrote that the results of special theory (including, I presume, its
concept of length contraction) are invalidated by gravitational fields
and whilst it is claimed that such effects are 'allowed for' I am of
the opinion that no-one as yet has explained what gravity actually is
nor how it causes matter to accelerate.

It seems that there are many people who seem to live in a fantasy
world where mathematical illusion is 'reality' i.e. that an object
will incur length contraction in its direction of travel because a
mathematical proposition 'shows' that it will!

There is no empirical evidence to support this mathematical
proposition.

*****************

No .. if anything by your stupidity.

I was informed by the author of that comment that I should not malign
people in these groups.

It is my opinion that people who resort to personal insults or
supercilious, condescending, comments are those who have never had an
original idea of their own thus are forced to denigrate those of us
who are capable of indicating ingenuity.
