A woman goes to the Doctor, wo...

A woman goes to the Doctor, worried about her husband's temper.
The doctor asks, "So what seems to be the problem?"
The woman says, "Doctor, I don't know what to do. Every day my husband seems to lose his temper for no reason at all. It's starting to scare me."
The Doctor tells her, "I think I have just the cure for that. When it seems your husband is getting angry, just take a glass of water and start swishing it in your mouth. Just swish, and swish, but don't swallow it until he leaves the room or decides to go to bed."
Two weeks later, the woman returns, looking fresh and reborn. The woman says, "Doctor, that was a brilliant idea! Every time my husband started to lose it, I swished with water. I swished and swished, and he calmed right down! How does a glass of water do that?!"
The Doctor informs her, "The water itself does nothing. It's having to keep your mouth shut that does the trick."

Paul Sabatier

Born 5 Nov 1854; died 14 Aug 1941 at age 86. Organic chemist who shared the Nobel Prize for Chemistry in 1912 with Victor Grignard. Sabatier researched in catalytic organic synthesis, and discovered the use of finely divided nickel as a catalyst in hydrogenation (the addition of hydrogen to molecules of carbon compounds). The margarine, oil hydrogenation, and synthetic methanol industries grew out of this work. He found that increasing the surface area of catalysts such as copper and nickel by finely dividing them greatly increases their effectiveness. Sabatier did wide-ranging research of the use of catalysts in organic chemistry syntheses, revealing metals other than nickel, though less effective, can also behave as catalysts.
