Syllabus of tutorials:

Solving problems to illustrate the theory from the lecture

Study Objective:

Knowledge:

Learn the basics of tensor calculus. Learn about the space on which Newtonian mechanics (Euclidean affine space) and special relativity (Minkowski spacetime) take place. Learn about groups of transformations and their role in physics: Galilei group (Galilei's principle of relativity), Lorentz group (Einstein's principle of relativity).

Apply knowledge of the tensor calculus to describe rigid body motion (moment of inertia tensor), the continuum (stress tensor and strain tensor), the electromagnetic field (electromagnetic field tensor, energy and momentum tensor).

Learn the basics of the Lagrangian formalism in classical field theory and apply them to the description of the electromagnetic field in Minkowski spacetime. This is the second part of the classical theoretical physics course at FNSPE.

Skills:

Application of methods of theoretical physics to solve concrete examples.
