Mathematics in itself tells us nothing about the world. As Hilbert said, if you can't substitute "beer mugs" et al for "points, lines, et al" then you haven't got to the heart of the mathematical proposition (or something to that effect).So you say that Mathematics can not be scientific truth? At least it is consistent with what humans believed for the majority of their existence I guess.
Mathematical physics tells us about the world because it is anchored in measurement.
The Ancient Greeks had excellent geometry, but they were able to use it to determine the circumference of the earth because they took measurements. Conversely, their astronomical theories suffered from the limitations of their observations, which were not sufficient to displace the geocentric theory.
[MENTION=16814]Ovinomancer[/MENTION] - the observation of moons around Jupiter is sufficient to disrupt the basic geocentric framework. Once other planets have moons in orbit about them, the posit of the earth as the centre of all orbits breaks down. (There is also the technical challenge of incorporating the moons of Jupiter into the then highly epicyclic state of geocentric theorising - I don't know enough of the history of that period to know if this was seriously attempted.)
