La Relativité Restreinte: Révolution Spatio-Temporelle

25 min

28 déc. 2025

Exploration technique des postulats d'Einstein qui ont transformé notre compréhension de l'univers, de la constance de la vitesse de la lumière aux transformations de Lorentz et à l'équivalence masse-énergie.

Meilleure citation de La Relativité Restreinte: Révolution Spatio-Temporelle

Au lieu de considérer la vitesse de la lumière comme relative dans un espace et un temps absolus, Einstein a proposé de considérer la vitesse de la lumière comme absolue dans un espace et un temps relatifs.
