Herman is correct, in almost all respects. I offer one exception, as listed below:

mathematics has not created any 'new' or 'old' physics.

Newton did not first come up with the mathematics associated with his physics. The physics came first, the math model second, as you cited several times, yet for some reason exempted Newton from this well know process.
I hope that you agree with this order of thinking, or provide a clear explanation.
