Poincaré symmetry

Poincaré symmetry is a concept from physics that describes how certain properties of space and time remain consistent under various transformations, like moving or rotating an object. Named after the mathematician Henri Poincaré, it combines two key ideas: translations (shifting an object) and Lorentz transformations (altering an object's speed and direction, especially near light). This symmetry is fundamental in both special relativity and quantum mechanics, helping to unify our understanding of the universe. Essentially, it tells us that the laws of physics are the same everywhere and at all times, regardless of how we move or change our perspective.
