Talk:Joseph Davidovits

Jana quote

That was copied, bad grammar and punctuation and all, straight from the pdf of his paper.--Dougweller (talk) 21:52, 23 February 2008 (UTC)

Wow! If I turned in such a paper, I'd be crucified. TuckerResearch (talk) 21:58, 23 February 2008 (UTC)

Well, he's a scientist.. it's a very detailed paper though, looks impressive!--Dougweller (talk) 22:03, 23 February 2008 (UTC)

Davidovits is a scientist too. I'm working on my Ph.D. in history. But, remember: intellectual brilliance is no guarantee against being dead wrong.TuckerResearch (talk) 22:45, 23 February 2008 (UTC)

Agreed. But my comment about him being a scientist was a sort of 'don't expect perfect English from a scientist' throw away comment.--Dougweller (talk) 14:48, 24 February 2008 (UTC)

I am not competent for the task, but it is a serious omission to cite Jana without including what seem to be convincing rebuttals (e.g., two articles this year, by J. Davitovits and by Guy Demortier) of Jana's article: the "Lauer sample" that was analyzed in impressive detail and shown to be natural is clearly, from photos, different from the real Lauer sample, and probably not even from the pyramid! --177.179.207.95 (talk) 03:03, 4 November 2020 (UTC)

Where is Guy Demortier's article? I can't find it. Doug Weller talk 17:36, 4 November 2020 (UTC)

One article is:

Demortier, G., 2020. Distribution of sodium and chlorine in samples of Egyptian pyramids. Geopolym. Archaeol, 1,

pp.1-9.

First, Geopolymer and Archaeology is published by the Geopolymer Institute and seemingly lacks review by independent third parties.

Finally, in my opinion, it is somewhat hypocritical to complain about the problems with the provenance of the Lauer sample when in the above article, it is stated on pages 8 and 9 of the artcile:

So I have no samples taken by myself. I received thirty pieces between 1995 and 2015, all unofficially taken by a wide variety of scientists: (10 people including 7 Belgian) physicists, chemists, engineer, geologist, geographer, biologist, egyptologist. vast majority, and especially the egyptologist, asked for anonymity and I promised everyone not to reveal their identity.

Adding details on my scientific career:

As you know, I did not write the previous article. I feel it is now time to provide some details on my scientific career for a better understanding on why and how I came to this controversial theory on pyramid construction. If you search on the Internet you'll find legends. For example in the USA, and consequently in the English scientific journals, my invention of geopolymer chemistry in the years 1970-80 is narrated like a fairy tale. According to it, it was during my study of the pyramids of Egypt that, Eureka, I got this intuition. In America, the fundamental and applied researches on geopolymers are funded, since 2002, by the US Air Force who finances several laboratories in the USA as well as in Australia. Indeed, in the June 2006 issue of Defense Technical Briefs, scientists of the Air Force Research Laboratory wrote (Go to http://www.defensetechbriefs.com/component/content/article/4660): In the 1970s, French Professor Joseph Davidovits investigated the construction of the Great Pyramids of Egypt. He concluded that they could not have been built from quarried rock, surmising that the large aluminosilicate based blocks that form the pyramids must have instead been synthesized in place. Prof Davidovits’ endeavor to explore the possible mechanisms for producing such blocks led, by 1979, to the practical invention of geopolymers .

Those who read my books (especially the recent book Why the Pharaohs built the Pyramids with Fake Stones know that this statement is totally wrong. The opposite happened, indeed. It is only after having invented the geopolymer chemistry that, armed with this new knowledge, I actually investigated the construction of the pyramids and claimed that they were built with agglomerated stone, instead of carved stone. To learn about geopolymer science and technologies go to the article Geopolymer in Wikipedia.

Myths have a hard life and I do not know if I ever will restore the truth. Prof. Joseph Davidovits (talk) 10:06, 1 February 2013 (UTC)Prof. Joseph Davidovits (talk) 10:16, 2 February 2013 (UTC)

Semi-protected edit request on 23 April 2020

Prof. Joseph Davidovits presented in July 2019, at the 11th annual Geopolymer Camp meeting at Saint-Quentin, France, his keynote on the "State of the geopolymer R. & D. 2019”. It is a review on what happened in 2018 and the first semester of 2019 on geopolymer science and applications. In his keynote, he developed following topics: - Celebrating the 40th anniversary of the Geopolymer Institute, 1979 - 2019 - Celebrating the 10th anniversary of the Geopolymer Camp, 2009 - 2019 - List of 35 real world geopolymer commercial applications - Ancient Geopolymers in South-American Monuments, Pumapunku/Tiwanaku, Lake Titicaca, Bolivia. - 3 Research topics: - - Creating standards for Geopolymers (example of testing the reactivity of metakaolin) - - Geopolymer Material for Radioactive waste, Particules and gaz pollution - - Forget about Fly Ash, go with Ferro-sialate geopolymer concrete.

His paper on geopolymers: inorganic polymeric new materials has been cited more than 3139 times since 1991, according to Google Scholar. Source: https://akademiai.com/doi/abs/10.1007/BF01912193

Characterisation, no sources

"Davidovits's method is not accepted by the academic mainstream."

What mainstream - Egyptologists or Geopolymer scientists? Also, it sounds like characterisation, even discrediting.

"His method does not explain the granite stones, weighing well over 10 tons, above the King's Chamber, which he agrees were carved."

Nor does he need to. The fact that either most or all of the granite blocks of the pyramids, and the statues, are poured rather than carved is a momentous discovery. 83.87.102.173 (talk) 17:03, 25 March 2024 (UTC)

Sources discussion

It seems Davidovits' assertions about how the pyramids were built might be discussed by other sources in the article. I think the question is, does this mention or discussion in the sources amount to significant coverage? In the first reference I think it does. I have managed to access it [1], and he is discussed in relation to his view on the materials that make up the pyramid blocks by a seemingly independent third party, i.e., the authors of this academic journal article With this next source, it is unclear to me how this relates to Davidovits [2]. ---Steve Quinn (talk) 02:50, 26 March 2024 (UTC)

What else is Joseph Davidovits noted for besides his ideas about how the pyramids were constructed?

Looking at the article about Joseph Davidovits as it is now written, it portrays him as being notable only for his ideas about how the pyramids were constructed. There must be other aspects of his life and research that are notable enough to be discussed in this article. Paul H. (talk) 02:42, 6 April 2024 (UTC)

Within the field of geopolymers Davidovits is very well established with >24000 citations, an h-index of 51, and is associated with the development of the field since the 1970s. Someone with a background in materials science and geopolymers could put together a fairly robust biography about their contributions to the field. -71.74.161.114 (talk) 12:21, 1 May 2024 (UTC)
