    The only way to define a point with zero size is using coordinates. So a point could be defined as (0,0,0) + (x,y,z) = (x,y,z) where x,y,z are the distances from the origin (0,0,0) along the...

    What I am trying to understand is "what is position" being the title of the thread. I am no closer to that. One cannot explain a physical thing like position with mathematical symbols and equations....

    position x is the distance from an origin. To have a distance you need to have two physical objects. Without those there is no distance and x is meaningless. It's indisputable. An observable...

    So the more precisely you make a real object approach a zero size point the more energy required until it passes some limit and starts to form a black hole or something. A true point is never...

    As I understand it the uncertainty principle is derived from the wave equation and one form is Dx * Dp >= h/2 where Dx is the standard deviation of position in the x direction and Dp is standard...
