Gravitational Waves,essive amount of completely new data in the next 10–20 years. The aim of this chapter is to provide an introductory overview on the topic. Contrary to the other chapters of the book, the discussion is not at a purely theoretical level, and some sections are devoted to observations and experimental f

Textbook 2018lism and the principle of least action. This method allows the complete theory to be constructed starting from a small number of assumptions, and is the most natural approach in modern theoretical physics. The book begins by reviewing Newtonian mechanics and Newtonian gravity with the Lagrangian for

Special Relativity, not propagate instantaneously with infinite velocity (an implicit assumption in the theory of Galilean relativity). In special relativity we have spacetime as the natural stage for the description of physical phenomena.

Riemannian Geometry,ome mathematical tools necessary to achieve this goal. We follow quite a heuristic approach. The term Riemannian geometry is used when we deal with a differentiable manifold equipped with a metric tensor.

,Einstein’s Gravity, metric of the spacetime. The Principle of General Covariance is not enough to determine the metric. We need the field equations of a specific gravity theory. With Einstein’s gravity, we refer to the gravity theory described by the Einstein–Hilbert action or, equivalently, by the Einstein equations.

Electromagnetism,sors change when we move from a Cartesian inertial reference frame to another Cartesian inertial reference frame, it is straightforward to realize that the equations are invariant under Lorentz transformations.
