    1. as i understand, one particle can be in two places at the same time. for instance tha particle that is building the table can be in the table
    and in the same time sumewere els. my question is are we talking about two particles or about one. if we are talking about one particle,
    what makes the table exist at the time the particle is sumewere els?

    2. what makes the string vibrate according to the string theory?

    (i'm apologizing for my poor english)

    It's one particle and it can be at many places at once. For a solid object, a particle's location will be constrained by the other particles of the object by the forces that hold the object together, the object itself being a sort of average of the locations of all the particles of that object. It should also be noted that the distance scale of the particle's uncertainty is microscopically small and wouldn't be noticed by ordinary viewing. Also, because the location of the object as a whole is an average of the locations of the individual particles, it's location is much more certain.

    A tensor equation that is valid in any coordinate system is valid in every coordinate system.
