- Bell’s theorem is a term encompassing a number of closely related results in physics, all of which determine that quantum mechanics is incompatible with local hidden-variable theories, given some basic assumptions about the nature of measurement. “Local” here refers to the principle of locality, the idea that a particle can only be influenced by its immediate surroundings, and that interactions mediated by physical fields cannot propagate faster than the speed of light. “Hidden variables” are supposed properties of quantum particles that are not included in quantum theory but nevertheless affect the outcome of experiments. In the words of physicist John Stewart Bell, for whom this family of results is named, “If [a hidden-variable theory] is local it will not agree with quantum mechanics, and if it agrees with quantum mechanics it will not be local.”
- Seattle Neighborhoods: Denny-Blaine — Thumbnail History (historylink.org)
The Denny-Blaine neighborhood of Seattle is located on Lake Washington between Madison Park and Madrona. It was developed just after the turn of the century by Elbert F. Blaine, an attorney and former Seattle Parks Commissioner, and by Charles L. Denny, son of Seattle founders Arthur Denny and Mary (Boren) Denny. They designed the neighborhood to follow the contours of the land, and included a series of hillside parks. The lots intermingle with streets, lanes, parks, fountains, and cul-de-sacs, virtually all of which have views of Lake Washington.
