50/50

A young man watched as an elderly couple sat down to lunch at McDonald's. He noticed that they had ordered just one meal, and an extra drink cup. As he watched, the old gentleman carefully divided the hamburger in half, then counted out the fries, one for him, one for her, etc, until each had exactly half.

Then the old man poured half of the soft drink into the extra cup and set that in front of his wife. The old man then began to eat, but his wife just sat watching him.

The young man felt sorry for them and asked "I'm sorry to intrude, but would you allow me to purchase another meal for your wife so that you don't have to split your food?"

The old gentleman said, "Oh, no, thank you. But you see, we've been married a long time, and everything has always been shared, 50/50."

The young man said, "Wow! That's commendable." He then turned to the wife and asked, "Aren't you going to eat your share?"

The wife replied "Not yet. It's his turn to use the teeth."

Safety lamp

In 1816, Sir Humphry Davy's safety lamp was first used in a coal mine. Deadly explosions had been a continual hazard caused by the flammable gas, methane, leaking out of the coal seams ignited by the flame of a miner's lamp. There had been previous attempts by others to make a safety lantern. Davy applied a scientific approach to determine the suitable fineness of wire gauze placed around the flame which would avoid ignition of flammable gas outside. He determined that the holes in the gauze should be less than 1/22 inch in diameter, and that the wire itself should be between 1/40 to 1/60 inch thick. Since the flame changed colour in the presence of methane, it also served as a warning to the miner to take protective action.«[Image: Davy safety lamp, circa 1816.]
