A pretty young college student...

A pretty young college student visited her professor's office after class. She glanced down the hall, closed his door and knelt down before him.
"I would do anything to pass this exam," she said. Leaning closer, she whispered seductively, "I mean, I would do anything."
He looked down at her and said, "You'll do anything?"
"Anything," she replied again.
His voice softened. "Anything," he repeated.
She smiled and again said, "Anything."
His voice turned to a whisper. "Would you...study?"

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.]
