the length of the periphery is measured to be 1000. Then, with the rods
still fixed on its periphery, the disk starts rotating. While it is
rotating, Einstein says:

"If the observer applies his standard measuring-rod.... tangentially to
the edge of the disc, then, as judged from the Galileian system, the
length of the rod will be less than 1..."

This implies that, as judged from the Galileian system, the length of
both the 1000 rods and the periphery they cover will be measured to be
less than 1000, e.g. 999. At this very moment however Einstein forces
the zombi to immediately forget the implication and accept, with
enthusiasm and love, the opposite assertion. From now on the zombi
should repeat with Einstein that, as judged from the Galileian system,
the length of the periphery is GREATER than 1000. The manifestation of
love is essential. Loving zombis will become professors. The
indifferent may not become professors.

Einstein paid some attention to this problem since he (unlike his
zombis) knew quite well what was at stake. So he made the rotating disk
bend and curve in such a way as to confuse the picture and make
impossible any verification of the idiotic claim that, judging from the
non-rotating system, the circumference of the rotating disk was longer
than that of a non-rotating disk. What was at stake? Of course,
Einstein discovery in his 1905 paper that confused additionally the
contradictory theory of Lorentz-Poincare: THE ASYMMETRICAL TIME
CONTRACTION. A clock at rest should run FASTER by a factor of 1/gamma
relative to a clock moving with a constant speed in a closed curve.
Einstein feared that some zombi might decide to divide the length of
the circumference by the period and if the rotating circomference were
not longer, the result would be tragic and the zombi's faith might be
undermined. The zombi may also decide to replace the rotating disk with
a rotating ring which would not bend and curve - another awful idea.

On the other hand, the idiotic time contraction introduced by Einstein
in his 1905 paper is the real basis of the theory of relativity - see:
