Abstract
In this chapter, we study the properties of strong supersonic explosions leading to a blast wave propagation. The so-called Sedov–Taylor–von Neumann (S–T–vN) approach is followed, which consists in finding a formal or numerical approximation in a self-similar schematization of the problem. Once the spherical propagation front time dependence has been found via a dimensional reasoning, the values of the internal quantities are determined by the solution of a system of ODEs. Application to the determination of the unknown amount of energy released by a bomb or a Supernova (SN) follows.

Note that the binding energy usually referred to in the literature as the amount of energy to give to a specific nucleus to disperse all its elements (nucleons) is the absolute value of the nucleus energy at rest.
