"Nel cantiere della Grande Piramide - Gli architetti egizi svelati"

Ai primi di febbraio 2012, uscirà in libreria per Ananke Editore, un’attesa novità nel panorama egittologico, dal titolo :

"Nel cantiere della Grande Piramide - Gli architetti egizi svelati" (una metodologia pratica per la costruzione della Grande Piramide, e non un’ennesima “teoria”).

L’autore, Marco Virginio Fiorini (*) architetto, forte di una lunga esperienza professionale e dopo anni di ricerca specifica sulla piramide di Cheope, accompagna il lettore a “fare un giro” all’interno del cantiere della piramide di Cheope per scoprire insieme i segreti degli architetti egizi.

Le fasi per innalzare l’edificio più studiato e famoso della storia, sono presentate in modo progressivo e facilmente comprensibile da tutti, in questo testo unico nel suo genere.

Un viaggio entusiasmante a ritroso nei millenni, un tuffo nella sorprendente tecnologia di un antico popolo geniale, un’avventura non facile da dimenticare.

------------------------
L’autore presenterà per la prima volta in pubblico questa tecnica, nella conferenza che si terrà il 23 febbraio 2012 alle ore 18, presso palazzo della Regione Piemonte in corso Stati Uniti 23 a To- rino, organizzata dall’Associazione Egittologica Seshat, presieduta dall’egittologa Dott.sa Maria Stella Mazzanti, coadiuvata dal Vice-Presidente Dott. Armando Buzzi. 
 
(*) Un chapitre de l'ouvrage de cet auteur a été publié, en mars 2011, sur Pyramidales.

Cap 200.000 pour "Pyramidales"

 
Auto-satisfaction ou pas : un moment de faiblesse est vite passé...

Je constate simplement qu’une pierre après l’autre, le blog Pyramidales s’est fait une petite place au soleil de l’égyptologie pour s’y installer comme une e-bibliothèque à la disposition de tous les passionnés de pyramides égyptiennes. J’en veux pour preuve la fréquentation constante et quotidienne qu’il enregistre, même depuis plusieurs mois qu’il tourne en roue libre, sans nouvel apport notable à son contenu.
Y sont présentées, avec plus ou moins de détails, de très nombreuses théories, hypothèses ou conjectures sur l’art et la manière mis en oeuvre par les bâtisseurs égyptiens pour la construction de leurs célèbres monuments du haut desquels - sauf l’honneur que je (ne) vous dois (pas) Monsieur Bonaparte - nos modernes technologies apprennent la modestie.

Pyramidales va donc d’ici peu franchir le cap des 200.000 visites. À qui l’honneur ?
Pour un blog-inventaire au contenu quelque peu ardu, quelque chose me dit que l’enjeu n’était, au départ, pas évident.
Ce blog ne serait rien sans la fantastique richesse de pensée et d’obstination à la recherche de la vérité qu’il relate, le plus impartialement possible.
Il n’aurait pas pu naître et grandir sans la confiance qui m’a été maintes fois manifestée.
Et là, tout à coup, l’auto-satisfaction s’évanouit, devenue franchement ridicule. Il n’y a plus de place qu’au merci cordial et amical.

Pyramidales ne m’appartient pas. Ne m’appartient plus. Il vous revient de lui faire poursuivre sa route... vers le cap des 300.000 !

"Imaging the Cheops Pyramid", by Huy Duong Bui

Éditions Springer, décembre 2011, XVII, 83 p. 51 illus., 39 in color.
"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)

Exploration des conduits d'aération dans la Grande Pyramide : une étude récapitulative

Keith Payne, un blogueur américain passionné d'égyptologie, a entrepris une étude récapitulative et synthétique des différents "chantiers" d'inspection des conduits dits "d'aération" dans la Grande Pyramide de Guizeh, depuis les recherches de Waynman Dixon jusqu'à l'exploration de Djedi.
C'est clair et bien ficelé, comme toujours avec Keith.
C'est à lire...


"Last May the Project Djedi Team caught the world’s attention, and imagination, when they announced that the robot crawler designed to explore the southern shaft leading out of the Queen’s Chamber of the Great Pyramid had transmitted back images of markings left behind by the pyramid’s builders.  Hidden behind a “door” that had either thwarted or limited previous attempts to investigate the shaft, the markings prompted much speculation about their nature and purpose.
The Djedi Project was back in the headlines at the end of December when New Scientist magazine named the discovery one of the Top 10 Science Stories of 2011.  For the next few articles, Em Hotep will bring you up to date on the history of the exploration of the mysterious shafts in the Great Pyramid.  This current article will cover the ground from Waynman Dixon up to the Pyramid Rover Project, with the next article focusing exclusively on Project Djedi.  This will be followed by a couple of very special interviews you will not want to miss."
