Apparent motion/Copernicus: there is a difference between the true motion of the earth and the true motions of the planets.
"true"/Copernicus: = relative to the sun.
Relative motion/Newton: (all observable B) always identifiable as the difference between true motion.
Phenomena/Fraassen: we call these relative (relational) structures phenomena.
Motions/Fraassen: are the structures that show the perceived motions (phenomena).
Phenomenon: a phenomenon is always identifiable with movements in a model -> "empirical structures": > Quantities/Physics/Fraassen. >Phenomena.
Absolute acceleration/Newton: absolute acceleration produces strain and compression in the phenomena. >Absoluteness.
Newton: would the center be in another constant absolute movement (not acceleration) the phenomena would not change because power is connected to acceleration not to speed.
Empirical adequacy: there is a model, so that all phenomena are identifiable with motions in the model (also historical, not perceived ones). >Models, >Empirical adequacy.
Two theories are empirically equivalent if they have both models that can perform this.
