Query: Supernova Remnant Evolution: from explosion to dissipation   Here is considered the full evolution of a spherical supernova remnant. We
start by calculating the early time ejecta dominated stage and continue through
the different phases of interaction with the circumstellar medium, and end with
the dissipation and merger phase. The physical connection between the phases
reveals new results. One is that the blast wave radius during the adiabatic
phase is significantly smaller than it would be, if one does notaccount for the
blast wave interaction with the ejecta.
