0068-0346 of knowledge was decidedly unitary, but, in the period between1790 and 1840, the special emphasis it placed on observation andresearch led to an unprecedented accumulation of data, accompanied bya rapid growth in scientific specialization. An example of thetensions created by this development is to

H. A. M. SneldersExamples include geodesics, harmonic functions, complex analytic mappings between suitable (e.g. Miller) manifolds, the Gauss maps of constant mean curvature surfaces, and harmonic morphisms, these last being maps which preserve Laplace’s equation.
