`  E4, you wrote on  that  so some comment about why you changed your mind about it might be in order (my political views should have nothing to do with it, if you are an honest researcher). Also, the article now claims that ``Hilbert gave credit to Einstein for introducing the field equations`` in the 1916 version of his article. He never did such a thing. Also, I am not even sure that Sauer makes such a claim. Your Sauer quote in footnote 2 is on p. 51 of the pdf version of Sauer's preprint published on arxiv.org. A page before Sauer writes ``But, in the published version, he explicitly gave Einstein credit for the introduction of the metric tensor ...`` whereas you wrote ``In the final form of that article, published on March 31, 1916, Hilbert gave credit to Einstein for introducing the field equations`` which I could not find in Sauer's article. Could you give the page number for the arXiv pdf file? - `
