| contents | Causality is one of the most fundamental -- and yet elusive -- concepts in physics. From its intuitive role in everyday experience to its formal and often implicit role in scientific theories, causality has challenged philosophers and physicists alike. In what follows, we take a brief historical and conceptual journey through classical and modern physics, tracing how causality has been treated, questioned, or protected in successive physical frameworks -- from Galilean mechanics to Newtonian dynamics, from Lagrangian and Hamiltonian formulations to special and general relativity, and finally to quantum mechanics and statistical physics. Our aim is to show how the notion of causality has repeatedly receded into the background of our most successful theories, even when it appears to be central to our everyday understanding of the world. |
