    > This "apparent randomness" of measurement results is equally true of chaotic classical systems; it's not something that only appears in QM. Is that a fair comparison? Yes, in eit…

    > But this isn't true. The MWI is completely deterministic, because wave function collapse never occurs, and wave function collapse is the source of all the indeterminism in the Co…

    >The correct statement is this: you can make an observation of a system which is not in an eigenstate of the measurement operator you are using. I should have distinguished better,…

    Is that really the case though? An observation collapses a wave function. The Copenhagen interpretation suggests that the collapsed state arises from a probability distribution, bu…

    You can make an observation of a system whose state is undetermined. By interrogating the system for its state, a state becomes determined. Suppose, for example, that you have a fl…

    >Does measurement have to include an agent? Could measurement mean interaction with other atoms? Indeed it can. Roughly put, if information about the state left the undetermined sy…

    If it dragged dominant EEG frequencies, that would suggest that the effect either alters thalamic pacemaking or otherwise takes over. This audio beat frequency may exist as an anal…

    This study in PLOS seems to agree with the results: http://journals.plos.org/plosone/article?id=10.1371/journal.... This study suggests some measurable effects, though not as simpl…

    How about cryptogenic stroke? http://www.ncbi.nlm.nih.gov/pubmed/23366107 I think it's relatively clear that the tech works in a controlled setting. It even works surprisingly well…

    Photoplethsymographic heart rate requires a lot of algorithmic compensation for noise and motion artifact. There are some pretty sophisticated strategies available for beat interpo…
