Oxford University Press

This chapter looks at the equations of motion of a particle and describes the conditions that they present. It is not always a minimum, more commonly a saddle point. This chapter follows the ancient method of Euler and Lagrange to derive this fact. The quantum mechanical origin of this principle is also outlined: the average over all paths is dominated by the extremum in the limit of small Planck's constant.

Keywords:   Planck's constant, Lagrange, saddle point
