Movement/Feynman: the laws of mechanics for each particle can be summarized in one sentence of three equations:

m(d²x/dt) = Fx, m(d²y/dt²) = Fy, m(d²z/dt²) = Fz. (11.1)

(s) I.e. the forces in the three directions of the dimensions.
This means that there is a possibility of measuring x, y, z along three mutually perpendicular axes and the forces along these directions, so that these laws apply.
Question: where do we put the starting point, from which the measurements must all be conducted?
Perhaps the center of the universe: Feynman: the symmetries show us that we will not find this point. It is not excellent!
