# 2: Kinematics and Dynamics

• 2.1: Spacetime Diagrams
Our focus now turns to generalizing the analysis of the many relativistic effects that we uncovered with thought experiments. We begin this quest with a nice graphical technique.
• 2.2: Lorentz Transformation
So far we have achieved results one at a time, through thought experiments. Here we will develop a more general mathematical framework to link inertial frames in relative motion which will work for the results we have already obtained, as well as any other new ideas that might come along.
