+**Path Integral**
+The Path Integral is a profound formulation in [Quantum Mechanics](/wiki/quantum_mechanics) that conceives the amplitude for a particle to travel between two points as the sum over all possible paths it could take. Each trajectory contributes a phase, and their interference reveals the quantum evolution, providing a cornerstone for [Quantum Field Theory](/wiki/quantum_field_theory).
