The Van der Corput lemma and equations in Physics

I will prove the Van der Corput lemma and then describe how it applies to partial differential equations arising in Physics. It will provide intuition for a number of qualitative properties of non-relativistic/relativistic massive particles and massless particles. For example, a single picture will show that relativistic massive particles have rest mass and cannot reach the speed of light.
