Prerequisites
It is recommended that students master the basics of classical mechanics as developed in the course LPHYS1111. Having passed LPHYS1221 is an asset.
Main themes
This teaching unit is a basic introduction to Einstein's special relativity.
The main themes tackled are geometry in space-time, kinematics and relativistic dynamics.

Learning outcomes
At the end of this learning unit, the student is able to : | |
| 1 | a. Contribution of the teaching unit to the learning outcomes of the programme AA1 : 1.1, 1.3, 1.4 AA2 : 2.1, 2.4 AA3 : 3.2, 3.5 b. Specific learning outcomes of the teaching unit At the end of this teaching unit, the student will be able : 1. to handle the concepts of metrics and invariants (from Euclid to Minkowski); 2. to go beyond classical prejudices as simultaneity is currently entirely relative and the addition of non-linear velocities (from Galileo to Einstein); 3. to move from an algebraic approach (Lorentz transformation as applied to a four-vector) to a geometric interpretation (in Minkowski's space-time) to describe phenomena such as time dilation and length contraction; 4. to apply relativistic formalism to particle disintegrations (at rest or in motion) and to elastic collision processes (Compton scattering, etc.) and inelastic collision processes (Mossbauer effect, etc.); 5. to apply relativistic formalism to gravitation (starting from a uniform acceleration motion) and to electromagnetism (starting from the Lorentz force); 6. to fully appreciate the impact (in the very long term) of fundamental research that feeds today's applied research. |
Content
The main themes addressed are :
1. Geometry in space-time: from rotation in a homogenous space to pseudo-rotation in causal space-time;
2. Relativistic kinematics: from Newton's first law (inertia) to conservation of the four-vector energy-momentum;
3. Relativistic dynamics: from Newton's second law (force) to the existence of electromagnetic (four-vector) and gravitational (tensor) fields.

Teaching methods
Apply physics and mathematics theories to resolve a problem.
We start from the principle that physics is a coherent representation of reality whose truth value rests upon FACTS to illustrate systematically, through phenomena observed in nature, all concepts inherent to the theory of special relativity.
Consequently, we choose :
- lecture presentations of theory with, in parallel, many applications in physics;
- exercise sessions covering other physics applications.
Justify the choice of methods and analysis tools used to solve known problems in physics.
Incoherence between Newton's mechanics and Maxwell's theory will lead to the development of a covariant theory with respect to the Lorentz transformations. Various exercises on the new mathematical objects that are the tensors will be proposed and solved.
Construct a physics argument and formalize it.
Development of concepts in physics and an introduction to new formalisms:
- from space-time geometry to Lorentz transformations;
- from relativistic kinematics to tensors;
- from relativistic dynamics to interaction fields.
