The new baby

A young mother finds out she is pregnant again, and she tells the good news to anyone who will listen. One day when the woman and the boy are out shopping, a friend of the mother asks the little boy if he was excited about the new baby.

"Oh, yes!" the little tyke says. And having overheard some of his parents' private conversations, he adds, "And I know what we are going to name it, too. If it's a girl we're going to call it Mary, and if it's another boy we're going to call it Quits."

Augustus De Morgan

Born 27 Jun 1806; died 18 Mar 1871 at age 64. English mathematician and logician who did important work in abstract symbolic logic, the theory of relations, and formulated De Morgan's laws: one is “NOT (A AND B) = (NOT A) or (NOT B)” and the other is “NOT (A OR B) = (NOT A) AND (NOT B)”. These laws continue to be applied in modern proof theory and for software programming. When he defined and introduced the term “mathematical induction” (1838), he gave the process a rigorous basis and clarity that it had previously lacked. He originated the use of the slash to represent fractions, as in 1/5 or 3/7. In Trigonometry and Double Algebra (1849) he gave a geometric interpretation of complex numbers.«[Born in India, De Morgan (according to Macfarlane) De Morgan considered himself to be British, without being specifically English, Scottish, Welsh or Irish.]
