Pyramids — Deep Misleading analysis on the “Lauer Sample”.

By

On 21 May 2020

In Archaeology, News

Hundreds of thousands of people have read articles and seen videos on the internet dealing with the pyramids of Egypt having been constructed from geopolymer concrete. The arguments of the opponents are always based on the same papers written by American geologists, published 15 to 30 years ago. The most cited study shown in the videos at YouTube is the analysis carried on the “Lauer Sample” by the American petrologist D. Jana, published in 2007. It is time to put an end to this pseudo-science.

What is the Lauer sample?

The controversy concerns the analysis performed on a sample of …

TWO OFFICIAL GEOPOLYMER CONFERENCES SCHEDULED EVERY YEAR
At the January 2009 Daytona Beach conference, Professor Joseph Davidovits (Geopolymer Institute, France) and Professor Waltraud Kriven (University of Illinois, USA) agreed to organize two official complementary and different conferences, every year:
– one located in the USA , in January, at Daytona Beach, Florida, Geopolymer Symposium within the Frame of the ICACC International Conference on Advanced Ceramics and Composites. This is a regular conference for scientists.
– the second in Europe, in July, in Saint-Quentin, France, the GeopolymerCamp: it is a gathering, a workshop, not a traditional conference.

Pyramide: le paléomagnétisme démontre la nature artificielle des pierres.

By

On 1 Feb 2013

In Archéologie

Une récente étude scientifique publiée dans la revue scientifique renommée « Europhysics News », Le Magazine de la Société Européenne de Physique, (2012), vol. 43, n ° 6, décrit comment l’étude du paléomagnétisme sur plusieurs pierres des pyramides démontre la validité de la théorie de Davidovits sur le caractère artificiel des pierres des pyramides égyptiennes.

Deux scientifiques, le Dr Igor Túnyi du Geophysical Institute SAS – Bratislava (République slovaque) et Ibrahim A. El-hemaly du National Research Institute of Astronomy and Geophysics, Le Caire, Egypte, ont fait l’hypothèse suivante (traduction de leur article scientifique en Anglais):

Paleomagnetism study supports Pyramid man-made stone

By

On 1 Feb 2013

In Archaeology

A recent scientific study published in the renown “Europhysics News“, The Magazine of the European Physical Society, (2012), Vol. 43, number 6, described how paleomagnetism study on several pyramid stones demonstrates the validity of Davidovits’ theory on the artificial nature of Egyptian pyramid stones.
Two scientists, Dr. Igor Túnyi from Geophysical Institute SAS – Bratislava (Slovak Republic) and Ibrahim A. El-hemaly from National Research Institute of Astronomy and Geophysics – Cairo, Egypt, made the following assumption (quote from their scientific paper):

Our paleomagnetic investigation of the two great Egyptian pyramids, Kufu and Khafre, is based on the assumption …

Révolution Géopolymère en marche

By

On 9 Nov 2011

In Information

Je suis heureux de constater comment la science des géopolymères, que j’ai fondée il y a 33 ans, donne lieu à des développements et innovations touchant le grand public. Ainsi, BASF, la World Chemical Company, assure une promotion importante de la technologie géopolymère. Dans un article précédent posté à l’Institut Géopolymère et daté du 24 Mars, 2011, nous avions présenté le nouveau produit géopolymère de BASF, le joint PCI-GEOFUG (allez à BASF). Entre temps, la société introduit cette nouveauté dans les principales foires et expostions internationales, partant de l’Allemagne, le Royaume Uni, puis maintenant la France, Paris, à BATIMAT …

I am happy to see how Geopolymer science, which I founded 33 years ago, is generating applications and innovations dedicated to the general public. BASF, the world Chemical Company is strongly promoting geopolymer technology. In an older post posted in the Geopolymer Institute on 24 March, 2011, we introduced the geopolymer grout PCI-GEOFUG (go to BASF). Meanwhile, the company presents it at various international fairs and expositions, starting from Germany over UK, and presently in Paris, at BATIMAT (8 Nov., 2011). It is interesting to follow the arguments outlined in the company technical brochures dedicated to this geopolymer grout …

Revenge for ridiculed scientists: 2011 Nobel Prize in Chemistry

By

On 24 Oct 2011

In News, Science

The revenge of the ridiculed scientists.
In September 2006, my article Publish or Perish: the disease of scientific research highlighted how the 2005 Nobel Prize winners in Medicine had been forbidden for years to publish the results of their research, simply because they contradicted what was taught in the faculties world-wide, and accepted by the majority of the scientific community at that time. The recent 2011 Nobel Prize in Chemistry, Daniel Schechtman, experienced a situation even more vexing. When in 1982, thirty years ago, he made his discovery of quasicrystals, the research institution that hosted him fired him because he …

La revanche des scientifiques ridiculisés.
En Septembre 2006, mon article Publish or Perish : la maladie de la recherche scientifique soulignait comment les lauréats du Prix Nobel de Médecine 2005 avaient été interdits de publier les résultats de leur recherche, tout simplement parce qu’elle contredisait ce qui était enseigné dans les facultés, et admis par la majorité de la communauté scientifique de l’époque. Le récent Prix Nobel de Chimie 2011, Daniel Schechtman, a fait l’expérience d’une situation plus vexante encore.
