Kind of Mist in Tacquet?

  • According to the Dutch observer of the moon A.J.M.Wanders, there should have been certain reports of a kind of mist in Tacquet. See pages 300 and 355 in the book Op Ontdekking in het Maanland (A.J.M.Wanders, 1949).- DannyCaes Jul 27, 2014


  • André Tacquet (June 23, 1612–December 22, 1660) was a Belgian mathematician. His work prepared ground for the eventual discovery of the calculus.
  • According to Whitaker (p. 218), this name was introduced by Schröter, although the names Tacquetti (p. 197) and Tacquettus, S.J. had been used previously by Van Langren and Hell, but for different formations. Schröter's spelling of "Taquet" was adopted into the original IAU nomenclature of Blagg and Müller, but "corrected" in Table III of Kuiper's Photographic Lunar Atlas, which was approved by the IAU in 1961. - Jim Mosher
