βΊThe special form of (1.18.28) is especially useful for applications in physics, as the connection to non-relativistic quantum mechanics is immediate: being proportional to the kinetic energy operator for a single particle in one dimension, being proportional to the potential energy, often written as , of that same particle, and which is simply a multiplicative operator.
