It's Time

An old lady tottered into a lawyer's office and asked for help in arranging a divorce. "A divorce?" asked the unbelieving lawyer. "Tell me, how old are you?"

"I'm eighty-four," answered the old lady.

"Eighty-four! And how old is your husband?"

"My husband is eighty-seven."

"My, my," said the lawyer, "and how long have you been married?"

"Next September will be sixty-two years."

"Married sixty-two years?! Why would you want a divorce now?"

"Because," the woman answered calmly, "enough is enough."

Alfred Werner

Died 15 Nov 1919 at age 52 (born 12 Dec 1866).Swiss chemist whose founding research into the structure of coordination compounds brought him the 1913 Nobel Prize for Chemistry. He demonstrated that stereochemistry was not just the property of carbon compounds, but was general to the whole of chemistry. His theory of chemical coordination (1893) recognized that many metals appeared to show variable valence and form complex compounds. Certain metals, such as cobalt and platinum, were capable through their secondary valences of joining to themselves a certain number of atoms or molecules. These were termed by Werner “coordination compounds.”and the maximum number of atoms (or “ligands”as he called them) that can be joined to the central metal is its coordination number.
