Synopsis:
 "Chaos" theory: a slight change in the initial conditions results in largescale differences
 Eternal return: every isolated system returns after a finite time to its initial state
 The speed of light is the maximum speed
 Mass depends on speed
 No experiment can discriminate between a state of uniform motion and a state of rest
 Lorentz transformations
 NonEuclidean geometries have the same logical and mathematical legitimacy as Euclidean geometry
