That book uses Poincaré's relativity remark ("the sun turns around the earth") for a geocentric argument. Poincaré disowned that reading at Lille (fr-wikisource notes). Recorded as a later use of the text by a fringe author; the book's own characterization of it is not adopted here.

Bearing

  • Date and provenance (all claims): the lecture was given at Göttingen on 28 April 1909, its French text was printed in 1910, and the English translation appeared in The Monist 23(3), July 1913, after Poincaré's death. facts.json's "[memory] medium ... about 1910" needs correcting.
  • Claim 5: secondary sources agree that Poincaré-type relativistic gravity gives about 7" per century for Mercury. That fits the "6"" in the Lille text.
