Universality in the Gravitational Stretching of Clocks, Waves and Quantum States
There are discernible and fundamental differences between clocks, waves and
physical states in classical physics. These fundamental concepts find a common
expression in the context of quantum physics in gravitational fields; matter
and light waves, quantum states and oscillator clocks become quantum synonymous
through the Planck-Einstein-de Broglie relations and the equivalence principle.
With this insight, gravitational effects on quantum systems can be simply and
accurately analyzed. Apart from providing a transparent framework for
conceptual and quantitative thinking on matter waves and quantum states in a
gravitational field, we address and resolve with clarity the recent
controversial discussions on the important issue of the relation and the
crucial difference between gravimetery using atom interferometers and the
measurement of gravitational time dilation.Comment: Gravity Research Foundation honorable mention, 201
Trajectories of the Effects of Sad Mood Induction Procedures (MIPs)
Mood Induction Procedures (MIPs) are used widely in cognitive vulnerability to depression research. Although research supports certain MIPs as effective, little research has validated the assumption that MIP-induced sad moods are sufficiently persistent. This study addressed three questions: How long does an MIP-induced mood last? What are the shapes of the trajectories of the mood effects? Do these trajectories differ by type of MIP? Four-hundred-and-one undergraduate students were randomly assigned to undergo one of three commonly used sad MIPs or a neutral MIP. Mood was repeatedly measured immediately prior to and following the MIP.Results did not support the widely held belief that commonly used MIPs induce a sufficient and persistent sad mood. Current theories of cognitive vulnerability may therefore be biased by empirical findings predicated on such assumptions. This study has profound implications for the validity of current conceptualizations of depression and recommendations for the treatment of this disorder
