Default TODAYS EINSTEINS AND THE PARADOX

Today's Einsteins in the Perimeter Institute suddenly declared a
crisis, a paradox, a revolution, and started an extremely hard work:

http://maisonneuve.org/index.php?&pa...rticle_id=2934
"CRISES + PARADOX = REVOLUTION. WELCOME TO THE PERIMETER INSTITUTE
WHERE TODAY'S EINSTEINS ARE HARD AT WORK."

I am not a subscriber to the magazine so I have not read the whole
paper but I am almost sure the paradox Today's Einsteins are tackling
is one involved in length contraction - an effect the field concept of
light (light as continuous structures) and its implication, Einstein's
second (light) postulate, predict:

http://www.math.ucr.edu/home/baez/ph...barn_pole.html
"These are the props. You own a barn, 40m long, with automatic doors
at either end, that can be opened and closed simultaneously by a
switch. You also have a pole, 80m long, which of course won't fit in
the barn....So, as the pole passes through the barn, there is an
instant when it is completely within the barn. At that instant, you
close both doors simultaneously, with your switch. Of course, you open
them again pretty quickly, but at least momentarily you had the
contracted pole shut up in your barn."

Today's Einsteins have discovered that, if the doors are not reopened
at all, a paradox emerges. The trapped pole must be both 40m long and
80m long. So Today's Einsteins will try to solve the paradox by
abandoning the field concept of light (light as continuous structures)
and its implication, Einstein's light postulate c'=c, and adopting
Newton's corpuscular theory of light and its implication c'=c+v, where
c' is the observed speed of photons, c is the initial speed of photons
relative to the light source and v is the relative speed of the light
source and the observer. The transition from c'=c to c'=c+v will be
extremely difficult and will take a lot of time and money but Today's
Einsteins are optimists by nature.
