mécanique quantique

Mécanique quantique is the branch of physics that describes the behavior of tiny particles, like atoms and electrons, at very small scales. Unlike everyday objects, these particles can exist in multiple states simultaneously and change unpredictably when observed. It introduces concepts like wave-particle duality, where particles can behave both as particles and waves, and quantization, meaning properties like energy come in discrete amounts. This theory explains phenomena that classical physics cannot, such as atomic stability and superconductivity, forming the foundation for modern technologies like semiconductors and quantum computers.
