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."

Edmund Davy

Died 5 Nov 1857 (born 1785). English chemist who discovered acetylene gas. He gained experience while assisting his cousin, Humphry Davy in his chemical researches at the Royal Institution. From 1813, he pursued a career as a professor of chemistry in Ireland. Edmund Davy was the first to discover a finely divided, spongy platinum with remarkable gas-absorptive and catalytic properties. In 1836, by heating potassium carbonate with carbon at very high temperatures, he produced a residue of what is now known as potassium carbide, (K2C2), which reacted with water to release a new gas he recognised as a “new carburet of hydrogen.” In 1860, during a thorough investigation of hydrocarbons, Marcellin Berthelot rediscovered the gas and coined its name “acetylene”«
