A man was wheeling himself frantically down the hall of the hospital in his wheelchair, just before his operation. A nurse stopped him and asked, "What's the matter?"
He said, "I heard the nurse say, 'It's a very simple operation, don't worry, I'm sure it will be all right.'"
"She was just trying to comfort you, what's so frightening about that?"
"She wasn't talking to me. She was talking to the doctor!"

Henry-Louis Le Chatelier

Born 8 Oct 1850; died 17 Sep 1936 at age 85.French chemist who is best known for the principle of Le Chatelier, which makes it possible to predict the effect a change of conditions (temperature, pressure, and concentration of reaction components) will have on a chemical reaction. This principle proved invaluable in the chemical industry for developing the most efficient chemical processes. Fritz Haber successfully utilized it in his process for the production of ammonia. Le Chatelier's interests began in metallurgy, cements, ceramics, and glass, and his studies of flames led him to study heat and its measurement. Of several contributions to thermometry, his most important was the first successful design of a platinum and rhodium thermocouple for measuring high temperatures (1887).
