IN BRIEF Electromagnetism: study of interactions between charged particles. Electromagnetic field: combination of electric and magnetic fields. An electric field is associated with a voltage. A magnetic field arises from moving electric charges. Both fields are inseparable and interact with each other. An electric current generates both an electric field and a magnetic field. The … Read more
IN BRIEF Symmetry: Fundamental concept in physics, reflecting the invariance of a system under transformations. Transformations: Symmetries can be associated with changes such as rotations or inversions. Symmetry groups: Mathematical structure that formalizes the relationships between symmetries and physical laws. Conservation: Each symmetry leads to the conservation of a physical quantity, according to Noether’s theorem. … Read more
IN BRIEF Big Bang: cosmic event marking the origin of the Universe according to the current cosmological model. Origins of the Universe: study of the conditions preceding and following the Big Bang. Formation Eras: the Universe evolved through the radiation era, followed by the matter era. String Theory: suggests that the Big Bang could be … Read more
IN BRIEF Gravitational waves: oscillations of the curvature of space-time. Produced by cosmic events such as supernovae and black holes. Validation of general relativity by Albert Einstein in 1916. Detection possible thanks to installations like LIGO. Important consequences for modern astrophysics and the study of universes. Access to invisible phenomena that enrich our understanding of … Read more

IN BRIEF Four fundamental forces: gravitational force, electromagnetic force, strong nuclear force, weak nuclear force. Gravity: attraction of all masses, the weakest force. Electromagnetism: framework force of matter and responsible for interactions between electric charges. Strong nuclear force: holds protons and neutrons bound in the atomic nucleus. Weak nuclear force: involved in certain forms of … Read more
IN BRIEF First law: Principle of inertia, an object at rest remains at rest, and an object in motion retains its velocity. Second law: Relationship between force, mass, and acceleration (F = ma). Third law: For every action, there is an equal and opposite reaction. Newton’s laws are the foundations of classical mechanics. Applications: used … Read more
