references: Norman [1458, ed. 1738 :"Maupertuis and Clairaut made up part of the Academie's small but youthful and pugnacious band of Newtonians, who believed the shape of the earth to be that of an oblate ellipsoid. The expedition's results, which supported the Newtonian theory of gravitation, were met with hostility at first"].
