"The author is an expert in theories and applications in Solid
Mechanics and Inverse Problems, a former professor at Ecole
Polytechnique and now works with Electricité de France on maintenance
operations on nuclear power plants. In the Autumn of 1986, after the end
of the operation on the King’s chamber conducted under the
Technological and Scientific Sponsorship of EDF, to locate a cavity, he
was called to solve a mathematical inverse problem, to find the unknown
tomb of the King and the density structure of the whole pyramid based on
measurements of microgravity made inside and outside of the pyramid.
This
book recounts the various search operations on the pyramid of Cheops
made at the request of the Egyptian and French authorities in 1986-1987.
After the premature end of the Cheops operation in the Autumn of 1986,
following the fiasco of unsuccessful drillings in the area suspected by
both architects G. Dormion and J.P. Goidin and microgravity
auscultation, EDF and CPGF (a geophysical company) teams continued their
researches with measurements already made, trying this time an
inversion of the Newton gravity equation for the entire pyramid and
using another theoretical team led by the author. The inverse problem
solution confirmed the results of auscultations, but found no cavity.
However, the image of the average density at the surface of the entire
pyramid forms a sort of square “spiral” probably related to the
construction method. In 2000, Jean-Pierre Houdin considered the author’s
results of 1988 as a confirmation of his theory of the internal ramp
tunnel. Since then the author has done additional research and found
that classical theories of the construction based on degrees and the
particular mode of stones filling can also report the same densitogram.
The book is richly illustrated with color figures. It is dotted with
information concerning Physics, Mechanics and the History of Egyptian
Antiquities. The book ends with the greatest mystery of the pyramid
about the unknown tomb of the King and a dream to see the tomb at an
unexpected place." (présentation de l'éditeur)
