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.”

Jacobus Henricus Van't Hoff

Born 30 Aug 1852; died 1 Mar 1911 at age 58. Dutch physical chemist who was the first winner of the Nobel Prize for Chemistry (1901) “in recognition of the extraordinary services he has rendered by the discovery of the laws of chemical dynamics and osmotic pressure in solutions.” In stereochemistry, in 1874, he identified the four chemical bonds of carbon as having a tetrahedral arrangement, which explained how certain moleculars can be arranged differently with the same atoms to give left- and right-handed isomers. (Achille Bel arrived independently at the same conclusion at about the same time.) With regard to the osmotic pressure of liquids, he derived laws (1886) for dilute solutions similar to the gas laws for gases by Robert Boyle and Joseph Gay-Lussac. These relationships enabled the experimental determination of the molecular weight of a substance in solution.«
