Nicolas Fatio de Duillier Nicolas Fatio de Duillier {'1': ", '2': ", '3': ", '4': "} (also spelled Faccio or Facio; 16 February 1664 – 12 May 1753) was a Swiss-born mathematician, natural philosopher, and inventor. He spent much of his adult life in England and Holland. Fatio is known for his work on the zodiacal light problem in astronomy, for originating the "push" or "shadow" theory of gravitation, for his close association with both Christiaan Huygens and Isaac Newton, and for his role in the Newton v. Leibniz calculus controversy. He also invented and developed the first method for fabricating jewel bearings for mechanical watches and clocks.
Jean-Baptiste Pérès Jean-Baptiste Pérès (1752–1840) was a French physicist best known for his 1827 pamphlet "Grand Erratum", a polemical satire, translated into many European languages, that attempted "in the interest of conservative theology, to reduce to an absurdity the purely negative tendencies of the rationalistic criticism of the Scriptures then in vogue" (as Frederick W. Loetscher described what he called "the celebrated pamphlet" in "The Princeton Theological Review" 1906) through humorously suggesting ways in which the history of Napoleon Bonaparte could be shown to be an expression of an ancient sun myth.
