Aula 1.1 - Função de Onda e Equação de Schrödinger | INTRODUÇÃO À MECÂNICA QUÂNTICA | Griffiths

In this first lecture of the Introduction to Quantum Mechanics series, based on the book by David J. Griffiths, we explore two fundamental concepts of quantum theory: the wave function and the Schrödinger equation. We begin by discussing the basic difference between Classical Mechanics and Quantum Mechanics. We then discuss the two-slit experiment, comparing the behavior of light and electrons, and discussing the interference pattern that reveals the dual nature of particles. Next, we introduce the wave function Ψ as a way of describing the quantum state of a particle, whose probabilistic interpretation is given by |Ψ|². We also present the Schrödinger equation, briefly showing its central role in the evolution of the wave function in a physical system. The lecture ends with a reflection on different interpretations of quantum mechanics (realistic, orthodox and agnostic), highlighting the philosophical implications of measurement and uncertainty.
