The last decade has seen a resurgence in the world of classical dynamic systems, and many of the things that have been overly mathematical at the time this book appears are the everyday tools of working physicists. This new version aims to take this development into consideration.

I've also tried to make the book more readable and bug-free. Since the first edition already contained many materials for one semester, only new material was added when some original elements could be dropped or simplified.

However, it was necessary to expand this chapter with the proof of K-A-M theory to allow for the current current in physics. This is not only to use the most accurate mathematics tools, but also to reassess the word "basic". What has been considered earlier has been considered a wasteful account, as a result of a deep principle.

Even Kepler's laws, which determine the radius of the orbits of the planets, which were transmitted in silence like mysterious nonsense, seem to indicate an unattainable truth through the surface observation: Platonic plume diameter ratios to radius. Of platonic plastered solids are illogical, but satisfy the lower order algebraic equations..
