50-50 partners

A very successful businessman had a meeting with his new son-in-law. "I love my daughter, and now I welcome you into the family," said the man. "To show you how much we care for you, I'm making you a 50-50 partner in my business. All you have to do is go to the factory every day and learn the operations."

The son-in-law interrupted. "I hate factories. I can't stand the noise."

"I see," replied the father-in-law. "Well then you'll work in the office and take charge of some of the operations."

"I hate office work," said the son-on-law. "I can't stand being stuck behind a desk all day."

"Wait a minute," said the father-in-law. "I just make you half- owner of a moneymaking organization, but you don't like factories and won't work in a office. What am I going to do with you?"

"Easy," said the young man. "Buy me out."

Jean-Gaston Darboux

Born 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.«
