Physics Fundamentals: Laws and Observations

This lecture introduces the fundamental concepts of physics, focusing on the purpose of physics, the enunciation of laws, and the prediction and correction of physical phenomena. It covers topics such as the choice of observables, the reality of physical laws, and the verification of predictions through measurements. The instructor explains the importance of predicting and correcting physical laws, using examples like the addition of velocities. The lecture also discusses the role of observers in physics, both from a relativistic and non-relativistic perspective, emphasizing the verification of predictions in different scenarios.
