Once there was a golfer whose drive landed on an anthill. Rather than move the ball, he decided to hit it where it lay. He gave a mighty swing. Clouds of dirt and sand and ants exploded from the spot. Everything but the golfball. It sat in the same spot.
So he lined up and tried another shot. Clouds of dirt and sand and ants went flying again. The golf ball didn't even wiggle.
Two ants survived. One dazed ant said to the other, "Whoa! What are we going to do?"
Said the other ant, "I don't know about you, but I'm going to get on the ball."

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.]
