If mathematical physicists are also taken into account then Butzer and Fehér believe that Christoffel would have to be compared with Green, Hamilton, Sylvester, Helmholtz, Cayley, Kirchhoff, Maxwell, Beltrami, Lie, Boltzmann, Poincaré and Fredholm . I [EFR] must say that I find it surprising that some of these mathematicians are considered by Butzer and Fehér to be mathematical physicists.
Kung matematiko physicists din sa mga kinuha sa account at pagkatapos ay Butzer at Fehér naniniwala na Christoffel ng nais na kumpara sa Green, Hamilton, Sylvester, Helmholtz, Cayley, Kirchhoff, Maxwell, Beltrami, humiga / magsinungaling, Boltzmann, Poincaré at Fredholm. I [EFR] ay dapat na sinasabi ko mahanap ito kagulat-gulat na ang ilan sa mga mathematicians ay itinuturing ng Butzer at Fehér na matematiko physicists.
