String theory: an introduction

La théorie des cordes : une introduction

IN BRIEF String theory: fundamental theoretical framework in physics. The fundamental objects are vibrating strings. Elementary particles correspond to the different vibrations of the strings. Famous for its ambition to be the “theory of everything”, unifying the forces of nature. Involves 11 dimensions in some formulations. A popularization necessary to make science accessible. Exploration of … Read more

Holographic principle in physics: is everything surface?

Le principe holographique en physique : tout est surface ?

IN BRIEF Holographic principle: central concept in theoretical physics. Suggests that the information of a system can be represented on its surface rather than within its volume. Related to the study of black holes and their event horizon. Indicates a relationship between gravity and quantum. Suggests that our universe could be similar to a hologram. … Read more
