= Curie's principle
{wiki=Curie's_principle}
Curie's principle, formulated by the French physicist Pierre Curie, states that "when a physical phenomenon exhibits symmetry, the causes of that phenomenon must also exhibit the same symmetry." In other words, if a system has a certain symmetry, any effects or changes resulting from that system should also respect that symmetry. This principle is particularly relevant in fields such as crystallography, material science, and physics in general, helping to predict how materials will behave under various conditions.
