Early one morning, a mother went in to wake up her son.
"Wake up, son. It's time to go to school!"
"But why, Mom? I don't want to go."
"Give me two reasons why you don't want to go."
"Well, the kids hate me for one, and the teachers hate me also!"
"Oh, that's no reason not to go to school. Come on now and get ready."
"Give me two reasons why I should go to school."
"Well, for one, you're 52 years old. And for another, you're the PRINCIPAL!"
Jean-Gaston DarbouxBorn 14 Aug 1842; died 23 Feb 1917 at age 74.French mathematician whose work on partial differential equations introduced a new method of integration (the Darboux integral) and contributed to infinitesimal geometry. He wrote a paper in 1870 on differential equations of the second order in which he presented the Darboux integral. In 1873, Darboux wrote a paper on cyclides and between 1887-96 he produced four volumes on infinitesimal geometry, including a discussion of one surface rolling on another surface. In particular he studied the geometrical configuration generated by points and lines which are fixed on the rolling surface. He also studied the problem of finding the shortest path between two points on a surface.« |
