Some Mechanical Problems in a Geometric Setting,ll textbooks, even the best, this Principle is presented in such a way that it is impossible to understand”. I do not choose to break with tradition” (Arnold, Mathematical Methods of Classical Mechanics, 2nd edn. Springer, New York, 1989).

Transformations, Symmetries and Noether Theorem,our space-time: homogeneity, isotropy, …. In this case, the Noether theorem states that conservation laws are consequences of these properties. For example, symmetry under spatial translations implies the conservation of the total momentum of a system.

For convenience, we have made the subject matter of the next chapter independent from this one, so the reader can omit this and continue from the next chapter. It is worth noting that time-independent canonical transformations are an important tool to analyze the structure of a general singular theory.
