    I found that Pay it forward works on so many levels. Something as simple as the shopping cart quarter.

    From the link: A statement that is equivalent to the parallel postulate is that there exists a triangle whose angles add up to 180. Since spherical geometry violates the parallel postulate, there exists no such triangle on the surface of a sphere. The sum of the angles of a triangle on a sphere is 180(1 + 4f), where f is the fraction of the sphere's surface that is enclosed by the triangle. For any positive value of f, this exceeds 180.
    I was wondering when a Mathematician would come along to dispute that.

    Wnen my Son was in High School he picked up a package of cigarette papers. This was at the height of the Pot Program. Both the Clerk and I gave him the evil eye. I mentioned it the other day. He explained then it was for machine tolerence. Said he has bought dozens over the years, but found that old pack in his tool box.

    I wonder how many guys here have done the same.
    Thanks from BigLeRoy

    I am sorry but spherical geometry is irrelevant to what I said.

    Any three points on the surface of the earth will still define a triangle and the triangle postulate still holds. It becomes a matter of spherical geometry IF the three sides of the triangle are arcs and not lines.

    And my point still holds -- whether you are talking of triangles in cartesian space or curved spaces. The domain of mathematics reside as IDEAS ONLY. What you get by measuring triangles in reality (which is what evidence is, by definition) are mere APPROXIMATIONS of mathematical laws.

    Is that clear?
