Patient 1: “Why did you run away from the operation table?”
Patient 2: “The nurse was repeatedly saying ‘don’t get nervous’, ‘don’t be afraid’, ‘be strong’, ‘this is a small operation only’, things like that.”

Crystal DetectorIn 1906, a U.S. patent was issued for the crystal detector, which was one of the first devices widely used for receiving radio broadcasts (until superseded by the triode vacuum tube). It was invented by Greenleaf Whittier Pickard, a U.S. electrical engineer. His patent described it as "a means for receiving intelligence communicated by electric waves." |
