npub1jy9a8k5prc8wn4jven7agerdchhyaweggg03xj0tz29xyzr9020snxz7ch (npub1jy9…z7ch) There is another argument favoring the Cartesian description of geometry in physics. A physical experiment is a measurement, which is a set of numbers. The only way to describe a line in physics it to give its equation in some coordinate system. I'm not saying that this is right. In fact physical theories break down at very short distances, so the idea of a dimensionless point is highly suspect.
