The falsification of Kepler's speculation that the spacing of the
could be explained by reference to Plato's five regular solids does not mark one of the significant landmarks in the progress of physics.
For example, the movement of the earth in
round the sun
Auringon ympäriproduces gravitational waves.
The analysis of
developed in Chapter 8 can also be applied when the parent body is a Schwarzschild black hole.
Since
can contain any finite number of symbols which repeat, it is clear that we can find a periodic orbit which passes arbitrarily close to any other trajectory in the strange invariant set.
Similarly, the gravity of the sun keeps

The mass of Jupiter was first calculated by Isaac Newton in the seventeenth century from the

Perturbations to
