Lecture
This lecture explores the consequences of Lorentz transformations in 1+1 dimensions for two observers O and O', parametrizing spacetime with variables (t, x) and (t', y). It discusses the relationship between the variables, the speed of O' measured by O, events observed at the same location but with time intervals, and the difference in time measurements between O and O'. Additionally, it analyzes the universe line of an object located 1 meter from O', immobile relative to O', and the implications of Lorentz transformations on its parametrization and distance from the origin.
