In this lesson we apply some fundamental philosophical principles to generate a Lagrangian function for the free particle. We examine the relativistic and non-relativistic case. The goal is to understand that when we are examining fundamental physical principles we will inevitably apply guesswork and experimentation to find plausible answers.
Next lesson: the Lagrangian of the electromagnetic field.
