Confusion about a point and a line

  1. May 25, 2014 #1
    A point has no dimension and a line, which has dimension, is made from points together. How does something without dimension create something with dimension? I can't really make any sense of it. Could you share your opinions?

    Did you try searching for an answer online?

    ... note: this is strictly a point of philosophy concerning the nature of infinity.
    You can get around it by redefining a point as an infinitesimal.

    As far as this forum is concerned (we don't do philosophy here) the study of mathematics has been arranged so these rules make sense and are useful. Just treat it as a definition.

    Yes, I searched a lot but still feel confused. I am doing some integrals and really curious.
    That makes sense.
    Is there an direct explanation to this even philosophy?

    See the link. Also research Xenos paradoxes.
    The questions are that old.
