    Graduate Does the environment cause wave function collapse

    This may be of interest: P264 of the book “Decoherence and the Quantum to Classical Transition” by Maximilian Schlosshauer describes the effect of differing densities of background gas on “double slit experiments” using C70 molecules. The C70 molecule is not a microscopic particle (but...

    Graduate Fourier Transform, and the uncertainty principle

    I thought the video was very good as well, I very much enjoyed it. Your link wouldn't work for me though, so just for completeness this link does work: http://www.youtube.com/watch?v=TcmGYe39XG0&list=PL5A6DBFFBEFF3A92E

    Graduate Ballentine's Ensemble Interpretation Of QM

    But the formal definition of scientific realism (you referred to the desirability of adopting a form of scientific realism in your post #293) states that there is a reality totally independent of phenomena along with the hypothesis that we do have access to the said reality in that we can say...

    Graduate Ballentine's Ensemble Interpretation Of QM

    Well I’m not sure about this. I know you have read some of d’Espagnat’s works, you may find this extract to be of interest - this is what he says about this particular criticism of operationalism that you seem to make. I would suggest the scientific realism you refer to is intended by...

    Graduate Ballentine's Ensemble Interpretation Of QM

    I understand that what you say above is entirely in the context of CI being miss represented, and it is within the outline of that interpretation you make the remarks concerning “observer created tripe” and “trees making sounds when there is no observer” and I don't want to detract from that at...

    Graduate Ballentine's Ensemble Interpretation Of QM

    Thanks, that clarifies my confusion over the terms "theory" and "interpretation" with regards to QM ensembles.

    Graduate Ballentine's Ensemble Interpretation Of QM

    Planck I think represents an outmoded paradigm within physics, though many seem still adhere to it. This is what Walter Moore said about Planck in his book on “Schrödinger, Life and Thought”: I hesitate to label you with any particular flavour of realism, though I would surmise it is close...

    Graduate Ballentine's Ensemble Interpretation Of QM

    Bernard d’Espagnat (in his book "on Physics and Philosophy") seems to forcefully describe the ensemble theory as requiring the existence of hidden variables – he refers to a “theory” rather than an “interpretation” which is the term used in this thread and on Wiki, but since d’Espagnat doesn’t...

    News Margaret Thatcher dies after stroke

    I have mixed feelings about her time in power – there is no question that something had to change in this country, the unions were rampant and strikes were common place, led in some instances by some very political union leaders. But in changing the country we lost a generation, mining...

    Graduate Why are Bell's inequalities violated?

    I agree with that extract you gave entirely, but of much more standing it is the considered viewpoint of Bernard d’Espagnat (see his book “Veiled Reality” amongst others). The emphasis with d’Espagnat however concerns independent reality (reality outside of the phenomena of empirical reality)...

    Graduate What do violations of Bell's inequalities tell us about nature?

    Yes I think I would agree very much with what you say in that you seem to be placing phenomena as the only entity in which we have access to and it is within that framework that we use the scientific method with spectacular success - why should we ask any more of such a successful method in...

    Graduate What do violations of Bell's inequalities tell us about nature?

    I only made the post in terms of a very small part of ttn’s overall important contribution to this thread, namely when he said: As I said in my post, I see nothing at all wrong in simply accepting that science (as an experimental discipline) belongs quite properly within phenomena. ttn seems to...

    Graduate What do violations of Bell's inequalities tell us about nature?

    I don’t follow this I’m afraid (or perhaps I should tentatively say I don’t agree with it!). Surely, all we have to work with is phenomena, the scientific method involving testability works within this framework and it is that framework that I refer to as empirical reality. This (our) reality of...

    Graduate How much can we rely on theories?

    I think your question concerns how much we can rely on physics outside of phenomena, though you may not quite see it framed in that all encompassing way, you were perhaps more thinking of how much we can rely on physics to tell us about that which lay "between" the phenomena (observation) of our...
