A student comes to a young pro...
A student comes to a young professor's office hours. She glances down the hall, closes his door, and kneels pleadingly. "I would do anything to pass this exam," she says. She leans closer to him, flips back her hair, and gazes meaningfully into his eyes. "I mean," she whispers, "I would do anything..." He returns her gaze, "Anything?" "Anything." His voice softens, "Anything?" "Anything," she repeats again. His voice turns to a whisper. "Would you ... study?"

John E. W. KeelyDied 18 Nov 1898 at age 71 (born 3 Sep 1827).John Ernst Worrell Keely was a fraudulent American inventor. In 1873 he announced that he had discovered a new physical force that, if harnessed, would produce unheard-of power. He claimed, for example, to be able to produce from a quart of water enough fuel to move a 30-car train from Philadelphia to New York City. He began construction of an engine to perform this feat and by 1874 was able to give preliminary demonstrations of his machine. He made a great show of guarding the secret of the motor he was developing to obtain power "from intermolecular vibrations of ether," and scientists and engineers scoffed at his unverified claims. |
