Thank you again, zahavasdad, for confirming my previous advice. You evidently do not understand that the shortest distance between two points on the surface of a sphere (without leaving the surface)is a “great circle,” i.e., a line that precisely bisects the sphere into two halves of equal volume and identical shape. The equator on a globe is an example of a meridian, and so is the pole-to-pole meridian, but a great circle can between any two points on the surface of a sphere.
Maybe you should study ontology, so you can have a parnassah taking care of cancer patients.
