When can we see the baby?

With all the new technology regarding fertility, an 88-year-old woman was able to give birth to a baby recently.

When she was discharged from the hospital and went home, various relatives came to visit. “May we see the new baby?” one of them asked.

“Not yet,” said the mother. “I'll make coffee and we can visit for a while first.”

Another half hour passed before another relative asked, “May we see the new baby now?”

“No, not yet,” said the mother.

A while later and again the guests asked, “May we see the baby now?”

“No, not yet,” replied the mother.

Growing impatient, they asked, “Well, when can we see the baby?”

“When it cries!” she told them.

"When it cries?” they gasped. “Why do we have to wait until it cries?”

“Because, I forgot where I put it.”

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.]
