Course contents
Introduction
Historical introduction and main landmarks in the development of the Special Theory of Relativity, the Galileian principle of relativity, inertial and non-inertial frames, the equivalence of inertial frames and the Galileain transformation.
The aberration of light, attempt to measure the dragging of aether, the experiments of Fizeau and Michelson-Morley. The Lorentz-FitzGerald contraction hypothesis, the increase of the mass of the electron with speed, the experiment of Kaufmann, Bucherer, Guye. Einstein proposal: the postulates of the theory of special relativity.
Relativistic Kinematics
The Lorentz transformation, the contraction of lenght and the time dilation. The transformation of velocity and acceleration, proper acceleration, Doppler effect and relativistic beaming.
Relativistic Dynamics
The definition of relativistic momentum and relativistic energy, the energy-mass equivalence, conservation of momentum and energy, transformation of momentum and energy, the zero-momentum frame of reference, Compton effect, transformation of force, the motion of a charged particle in a constant electric and magnetic fields.
Minkowski's space-time and four-vectors
Space-time and four-vectors, Lorentz transformations as rotations in space-time, Minkowski Diagram and geometric interpretation of relativistic effects, Mandelstam's variables.
Relativistic electrodymanics
The transformation of the electric and the magnetic field, covariant formulation of Lorentz's froce and Maxwell's equations, fields of a moving electric charge.
