Galilean Transformations: Spacetime and Measurements

This lecture covers the concept of Galilean transformations in the context of spacetime and measurements, focusing on the structure of spacetime, temporal coordinates, measurement of time, and norm calculations. The instructor explains the transformation of coordinates and distances, defining events, durations, and distances between events. The lecture also introduces the concept of Galilean transformations as bijective applications preserving distances and durations, with a focus on affine transformations. The content emphasizes the measurement of time, norm calculations, and the transformation of temporal coordinates.
