Logo of KEXP-FM

KEXP-FM (90.3 FM) is a non-commercial radio station in Seattle, Washington, United States, specializing in indie music programmed by its disc jockeys. KEXP's studios are located at the Seattle Center, and the transmitter is in the city's Capitol Hill neighborhood. The station is operated by the non-profit entity Friends of KEXP, an affiliate of the University of Washington. Since March 2024, KEXP-FM's programming has been rebroadcast over Alameda, California–licensed KEXC, which serves the San Francisco Bay Area. As well as daily variety mix shows featuring mostly alternative rock music, KEXP hosts weekly programs dedicated to other musical genres. Founded in 1972 as KCMU, the student-run station of the University of Washington, KEXP gained recognition for its influence on the regional music scene. It was the first station to air grunge bands like Nirvana and Soundgarden in the late 1980s. In 2014, the university transferred the FCC license of KEXP-FM to Friends of KEXP. (Full article...)

Many-worlds interpretation

The many-worlds interpretation (MWI) is a philosophical position about how the mathematics used in quantum mechanics relates to physical reality. It asserts that the universal wavefunction is objectively real, and that there is no wave function collapse. This implies that all possible outcomes of quantum measurements are physically realized in some "world" or universe. In contrast to some other interpretations of quantum mechanics, the evolution of reality as a whole in MWI is rigidly deterministic and local. Many-worlds is also called the relative state formulation or the Everett interpretation, after physicist Hugh Everett, who first proposed it in 1957. Bryce DeWitt popularized the formulation and named it "many-worlds" in the 1970s. This graphic illustrates the many-worlds interpretation of Schrödinger's cat, a popular thought experiment concerning quantum superposition, depicting the experiment's different outcomes as two branching strips of film stock. Every quantum event is a branch point; the cat is both alive and dead, even before the box is opened, but the "alive" and "dead" cats are in different branches of the multiverse, both of which are equally real, but which do not interact with each other.
