    The Logic of Experimental Tests, Particularly of Everettian Quantum Theory

    Get PDF
    Claims that the standard methodology of scientific testing is inapplicable to Everettian quantum theory, and hence that the theory is untestable, are due to misconceptions about probability and about the logic of experimental testing. Refuting those claims by correcting those misconceptions leads to various simplifications, notably the elimination of everything probabilistic from fundamental physics (stochastic processes) and from the methodology of testing ('Bayesian' credences)

    Programmable networks for quantum algorithms

    Full text link
    The implementation of a quantum computer requires the realization of a large number of N-qubit unitary operations which represent the possible oracles or which are part of the quantum algorithm. Until now there are no standard ways to uniformly generate whole classes of N-qubit gates. We have developed a method to generate arbitrary controlled phase shift operations with a single network of one-qubit and two-qubit operations. This kind of network can be adapted to various physical implementations of quantum computing and is suitable to realize the Deutsch-Jozsa algorithm as well as Grover's search algorithm.Comment: 4 pages.

    A Concise History of Western Music for Film-makers

    Get PDF
    The use of music in films has become almost ubiquitous in both drama and documentary. Music is used regularly in cinema, broadcasting and more recently, in interactive media. Yet audiences often criticise makers for its overuse, especially in actuality television. The problem is not merely concerned with the volume and placement of music, but of the internal nature and structure of the musical material itself. This article contextualises the history of western music in a way which may be able to help inform film makers and broadcasters about how music might be used more advantageously to accompany moving pictures

    Harnessing the Power of Music & Sound Design in Interactive Media

    The history of the development of sound on film offers us lessons for the development of sound and music for interactive artforms. Now that technological developments have enabled almost unrestricted importation of audio into interactive platforms, the time has come for us to ask: is the content of the audio good enough

    Psycho and The Orchestration of Anxiety

    Get PDF
    Since its release in 1960, Alfred Hitchcock’s Psycho has entered the consciousness of our culture as have few other films. Its striking imagery, combined with its universally recognised score, has prompted a wealth of scholarly output. New understanding in the areas of emotion and cognition now affords us the opportunity to re-examine this film from a less familiar vantage point. This article places Psycho within the context of American TV drama of the 1950s and explores the effect of Bernard Herrmann’s music on the emotional responses of the viewer, as well as the possible consequences of this effect upon the literal reading of the film

    Correlated Fast Ion Stopping in Magnetized Classical Plasma

    Get PDF
    The results of a theoretical investigation on the stopping power of ion pair in a magnetized electron plasma are presented, with particular emphasis on the two-ion correlation effects. The analysis is based on the assumptions that the magnetic field is classically strong (λB≪ac≪λD\lambda_B\ll a_c\ll \lambda_D, where λB\lambda_B, aca_c and λD\lambda_D are respectively the electron de Broglie wavelength, Larmor radius and Debye length) and that the velocity of the two ions is identical and fixed. The stopping power and % vicinage function in a plasma are computed by retaining two-ion correlation effects and is compared with the results of the individual-projectile approximation.Comment: LaTeX, 7 pages, 4 figure
