    Well, this is one interesting topic which I frequently think about. Can someone enlighten me about how far we know why the electron behaves this way when its being observed? I've seen "What the Bleep do we know", pretty good from a more general standpoint. I just want to know the answers so urgently

    NOT a good start.
    it’s not about physics... it’s a propaganda film
    What the Bleep Do We Know draws heavily on the role of the observer in quantum physics. Unfortunately, it also completely misunderstands it.
    David Albert is the physicist from Columbia University. Here's what he has to say about the movie: "I was edited in such a way as to completely suppress my actual views about the matters the movie discusses.
    Etc.
    It's a schlock "new age" piece of rubbish using physics terms to "support" its nonsense.

    Then leave it alone and it'll go to sleep!

    A reasonable start is here.

    Well, I was thinking so as I was like "WT#" through half the film when they said spirituality... looks like I'm safe.

    And what bothered me was Schrodigner's cat + What the Bleep do we know.

    I'll forgive you then. Provisionally.

    The Wiki article linked above IS a reasonable start, and we do have quite a few people here who can answer (probably) just about any question you'd like to ask.
    There are a couple of threads already existing.
    Here, here, and here for example.

    One of the best and simplest and most thorough books I’ve ever seen on the collapse of the wave function is Nick Herbert’s “Quantum Reality.” It's been available for ages.

    He’s a real physicist who disciplines himself to very main stream physics in this book. In some other books of his he treats some way out subjects, but in “Quantum Reality” it’s very main stream.

    Dear Naturelles:

    It is easier if you think of the electron as a wavepacket (Bohmian probability wave) travelling without dispersion. This way you avoid anything 'collapsing'.
