I Am Not Forgetful

Three ladies were discussing the travails of getting older. One said, "Sometimes I catch myself with a jar of mayonnaise in my hand, while standing in front of the refrigerator, and I can't remember whether I need to put it away, or start making a sandwich."

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”«
