Visualizing Frames of Reference and Relative Motions
The Principle of Relativity "The laws of physics are the same in all inertial reference frames." EVERYTHING strange and wonderful about special relativity follows as a "logical consequence" of this statement.

Visualizing Definitions * Event Observer Spacetime Coordinate (t,x,y,z) Reference Frame Synchronized clock Lattice
Comprehensive Statement An event is an occurrence happening at a definite place in space and instant in time described by a spacetime coordinates (t,x,y,z) as measured by an observer in a reference frame defined as a rigid cubical lattice of synchronized clocks.
Newtonian Viewpoint and Convention Synchronize clocks by carrying master clock from point to point on the lattice. Home Frame (x, y, z) Other Frame (x', y', z') t=0 when frames at same point
Galilean Transformations t' = t x' = x - t y' = y z' = z v x ' = v x - v y ' = v y v z ' = v z x tt x' a x ' = a x a y ' = a y a z ' = a z
