Definition: In particle physics, a boson is a type of particle that obeys the rules of Bose-Einstein statistics.omposite Bosons. 1  Mesons-Mesons are formed when two quarks bond together. 2  Since quarks are fermions and have half-integer spins, if two of them are bonded together, then the spin of the resulting particle (which is the sum of the individual spins) would be an integer, making it a boson.
Elk Grove, California. Elk Grove is a city in Sacramento County, California, located just south of the state capital of Sacramento. It is part of the SacramentoâArden-ArcadeâRoseville Metropolitan Statistical Area. As of 2015, the population of the city was estimated at 167,965.
The official plat of the 210-acre town was approved by the U.S. Department of the Interior on November 22, 1902. Lots were sold in 1904â05. With 1907 statehood Grove, the only incorporated town in Delaware County, became the county seat. Located midway between the county's eastern and western borders, Grove was about five miles from the county's northern border with Ottawa County. This placement became a problem for residents who wanted a seat of government closer to the county's center.
