In fact this change of direction by Betti towards mathematical physics led to him substituting chairs at Pisa in 1870 as we remarked above. Dini, who Betti had taught earlier, was appointed to fill his chair of analysis and higher geometry.
Sa katunayan ang pagbabagong ito ng direksyon sa pamamagitan ng Betti sa matematika physics na humantong sa kanya substituting upuan sa Pisa sa 1870 bilang namin remarked sa itaas. Dini, na Betti had tinuturuan mas maaga, ay hihirangin upang mapunuan ang kanyang upuan ng pagtatasa at mas mataas na geometry.
