1. I'm thinking of Lorenz contractions and Einsteinian relativity.

2. In the Einsteinian universe, time is not absolute.

3. But whether we are dealing with Newtonian or Einsteinian physics and whether space is infinite or finite, space is represented by a 3-manifold.

4. No one is tearing up the Einsteinian rule book just yet. As physicists well know, astonishing results like this often turn out to be wrong, especially when they haven't been double-checked.

5. They are active ingredients of an animate geometry that embraces the linear and non-linear. Both Cartesian and post Einsteinian geometry are encompassed by it.

6. The registers and players all use some kind of photocell, but what is more interesting from an Einsteinian perspective is the red beam of coherent light they shoot.

7. By the time the higher elevations are reached, such strange notions as Einsteinian curved space-time and the quantum uncertainty principle, heavy meals indeed, seem not so difficult to digest.

8. The Parkes radio telescope in Australia has been monitoring 20 pulsars once every two weeks since 2004 and has yet to see any gravitational waves, Einsteinian or otherwise.

9. Could spacetime literally be a kind of fluid, like the ether of pre- Einsteinian physics?
