references: Norman [880 : "Gauss's interest in geodesy led him to write his 'General investigations of curved sufaces', which gave the definitive treatment of the differential geomtry of surfaces lying in three-dimensional space. It also advanced the radical concept that a surface is a space in itself-a concept implicating the existence of a non-Euclidean geometry"], DSB : [V, p. 304 : "The crowning contribution of the period, and his last breakthrough in a major new direction of mathematical research was Disquisitiones generales circa superficies curvas (1828), which grew out of his geodesic meditations of three decades and was the seed of more than a century of work on differential geometry"].
