Betty, the town gossip and self-appointed supervisor of the town's morals, kept sticking her nose into other people's business.
Most local residents were unappreciative of her activities, but feared her enough to maintain their silence. However, she made a mistake when she recently accused Ted, a local man, of being an alcoholic after she saw his pickup truck parked outside the town's only bar one afternoon.
Ted, a man of few words, stared at her for a moment and walked away. Later that evening, he parked his pickup truck in front of her house and left it there all night.

Heinrich Rohrer

Born 6 Jun 1933.Swiss physicist who, with Gerd Binnig, received half of the 1986 Nobel Prize for Physics for their joint invention of the scanning tunneling microscope. (Ernst Ruska received the other half of the prize.) Ruska's electron microscope of the 1930s was unable to show surface structure at the atomic level. Rohrer and Binnig began work in 1978 on a scanning tunneling microscope in which a fine probe passes within a few angstroms of the surface of the sample. A positive voltage on the probe enables electrons to move from the sample to the probe by the tunnel effect, and the detected current can used to keep the probe at a constant distance from the surface. As the probe moves in parallel lines, a 3D image of the surface can be constructed.
